Conn. Gen. Stat. § 12-700a Alternative minimum tax.

12-700a. Alternative minimum tax. (a) Every resident individual, as defined in section 12-701, subject to and required to pay the federal alternative minimum tax under Section 55 of the Internal Revenue Code shall pay, in addition to the tax imposed under section 12-700, the net Connecticut minimum tax. The tax shall be the difference computed by subtracting the tax imposed under subsection (a) of section 12-700 from the Connecticut minimum tax, as provided in subdivision (26) of subsection (a) of section 12-701. The provisions of this subsection shall apply to resident trusts and estates, as defined in said section 12-701, and, wherever reference is made in this section to resident individuals, such reference shall be construed to include resident trusts and estates, provided any reference to a resident individual's Connecticut adjusted gross income shall be construed, in the case of a resident trust or estate, to mean the resident trust or estate's Connecticut taxable income. (b) Every nonresident individual, as defined in section 12-701, subject to and required to pay the federal alternative minimum tax under Section 55 of the Internal Revenue Code shall pay, in addition to the tax imposed under section 12-700, the net Connecticut minimum tax, as calculated herein. The tax shall be the difference computed by subtracting the tax imposed under subsection (b) of section 12-700 from the product of the nonresident individual's Connecticut minimum tax, as provided in subdivision (26) of subsection (a) of section 12-701, multiplied by a fraction, the numerator of which is the amount of income associated with the nonresident individual's adjusted federal tentative minimum tax that is derived from or connected with sources within this state, as such phrase is defined in sections 12-711 and 12-713, and the denominator of which is the amount of income associated with the nonresident individual's adjusted federal tentative minimum tax that is derived from or connected with sources within and without this state. The provisions of this subsection shall apply to nonresident trusts and estates, as defined in said section 12-701, and, wherever reference is made in this section to nonresident individuals, such reference shall be construed to include nonresident trusts and estates, provided any reference to a nonresident individual's Connecticut adjusted gross income shall be construed, in the case of a nonresident trust or estate, to mean the nonresident trust or estate's Connecticut taxable income. (c) Every part-year resident individual, as defined in said section 12-701, subject to and required to pay the federal alternative minimum tax under Section 55 of the Internal Revenue Code shall pay, in addition to the tax imposed under section 12-700, the net Connecticut minimum tax, as calculated herein. The tax shall be the difference computed by subtracting the tax imposed under subsection (c) of section 12-700 from the product of the part-year resident individual's Connecticut minimum tax, as provided in subdivision (26) of subsection (a) of section 12-701, multiplied by a fraction, the numerator of which is the amount of income associated with the part-year resident individual's adjusted federal tentative minimum tax derived from or connected with sources within this state, as such phrase is defined in section 12-717, and the denominator of which is the amount of income associated with the part-year resident individual's adjusted federal tentative minimum tax that is derived from or connected with sources within and without this state. For the purposes of such calculation, the provisions of subsection (c) of said section 12-717 providing for the accrual of items of income, gain, loss or deduction shall apply to the calculation of the part-year resident individual's adjusted federal tentative minimum tax. The provisions of this subsection shall apply to part-year resident trusts, as defined in said section 12-701, and, wherever reference is made in this section to part-year resident individuals, such reference shall be construed to include part-year resident trusts, provided any reference to a part-year resident individual's Connecticut adjusted gross income shall be construed, in the case of a part-year resident trust, to mean the part-year resident trust's Connecticut taxable income. (d) (1) For taxable years beginning on or after January 1, 1994, a credit shall be allowed as provided herein in an amount equal to the excess, if any, of the adjusted net Connecticut minimum tax imposed for all prior taxable years beginning on or after January 1, 1993, over the amount allowable as a credit under this subsection for such prior taxable years. (2) The credit allowable for a taxable year under this subsection is limited to the amount, if any, by which (A)(i) the tax imposed under section 12-700, (ii) less the credit, if any, allowed under section 12-704 exceeds (B)(i) the Connecticut minimum tax, determined without regard to whether the individual or the trust or estate is subject to and required to pay for that taxable year the federal alternative minimum tax under Section 55 of the Internal Revenue Code, (ii) less the credit, if any, allowed under subsection (e) of this section. (e) A resident or part-year resident shall be allowed a credit against the tax otherwise due under this section in the amount of any similar tax imposed on such resident or part-year resident for the taxable year by another state of the United States or a political subdivision thereof or the District of Columbia on income which is derived from sources therein and which is also subject to tax under this section. In the case of a resident, the credit provided under this subsection shall not exceed the proportion of the tax otherwise due under this section that the amount of the taxpayer's adjusted federal tentative minimum tax derived from or connected with sources in the other taxing jurisdiction, as the phrase is used in section 12-704, bears to the taxpayer's adjusted federal tentative minimum tax. In the case of a part-year resident, the credit provided under this subsection shall not exceed the proportion of the tax otherwise due during the period of residency that the amount of the taxpayer's adjusted federal tentative minimum tax derived from or connected with sources in the other taxing jurisdiction, as the phrase is used in said section 12-704, during the period of residency bears to such taxpayer's adjusted federal tentative minimum tax during the period of residency, nor shall the allowance of the credit provided under this subsection reduce the tax otherwise due under this section to an amount less than what would have been due if the amount subject to similar taxation by such other jurisdiction were excluded in the calculation of the adjusted federal tentative minimum tax.

Conn. Gen. Stat. § 12-702a Relief from joint tax liability.

12-702a. Relief from joint tax liability. (a) Any individual who has made a joint return under this chapter may elect to seek relief under the provisions of subsection (b) of this section and if such individual is eligible to elect the application of subsection (c) of this section, such individual may, in addition to any election under subsection (b) of this section, elect to limit such individual's liability for any deficiency with respect to such joint return in the manner prescribed under subsection (c) of this section. Any individual who has made a joint return under this chapter may elect to seek relief under the provisions of subsection (f) of this section, even if such individual is not eligible to seek relief under subsection (b) or (c) of this section. (b) (1) Under procedures prescribed by the commissioner, if (A) a joint return has been made for a taxable year and on such return there is an understatement of tax attributable to erroneous items of one individual filing the joint return; (B) the other individual filing the joint return establishes that in signing the return such other individual did not know, and had no reason to know, that there was such an understatement; (C) taking into account all the facts and circumstances, it is inequitable to hold such other individual liable for the deficiency in tax for such taxable year attributable to such understatement or portion of such understatement, as the case may be; and (D) such other individual elects the application of this subsection, in such form as the Commissioner of Revenue Services may prescribe, not later than the date which is two years after the date the commissioner has begun collection activities with respect to the individual making the election, such other individual shall be relieved of liability for tax, including interest, penalties and other amounts due for such taxable year to the extent such liability is attributable to such understatement. (2) If the electing individual satisfies the conditions of subdivision (1) of this subsection except subparagraph (B) of said subdivision (1), and establishes that in signing the return such individual did not know, and had no reason to know, the extent of such understatement, such individual shall be relieved of liability for tax, including interest, penalties and other amounts due for such taxable year to the extent such liability is attributable to the portion of such understatement of which such individual did not know and had no reason to know. (c) (1) If an individual who has made a joint return for any taxable year elects the application of this subsection, the individual's liability for any deficiency which is assessed with respect to the return shall not exceed the portion of such deficiency properly allocable to such individual under subsection (d) of this section. (2) The electing individual shall have the burden of proof with respect to establishing the portion of any deficiency allocable to such individual. (3) An individual shall be eligible to elect the application of this subsection if (A) at the time such election is filed, such individual is no longer married to, or is legally separated from, the individual with whom such individual filed the joint return to which the election relates, or (B) such individual was not a member of the same household as the individual with whom such joint return was filed at any time during the twelve-month period ending on the date such election is filed. (4) If the commissioner demonstrates that assets were transferred between individuals filing a joint return as part of a fraudulent scheme by such individuals, an election under this subsection by either individual shall be invalid. (5) If the commissioner demonstrates that the individual electing under this subsection had actual knowledge, at the time such individual signed the return, of any item giving rise to a deficiency or portion thereof which is not allocable to such individual under subsection (d) of this section, the election shall not apply to such deficiency or portion thereof, unless the individual with actual knowledge establishes that the electing individual signed the return under duress. (6) The portion of the deficiency for which the individual electing under this subsection is liable shall be increased by the value of any disqualified asset transferred to the individual. For purposes of this section, “disqualified asset” means any property or right to property transferred to an electing individual with respect to a joint return by the other individual filing such joint return if the principal purpose of the transfer was the avoidance of tax or payment of tax. Any transfer which is made after the date which is one year before the date on which a notice of proposed deficiency assessment is sent, other than any transfer pursuant to a decree of divorce or separate maintenance or a written instrument incident to such a decree or to any transfer which an individual establishes did not have as its principal purpose the avoidance of tax or payment of tax, shall be presumed to have as its principal purpose the avoidance of tax or payment of tax. (7) An election under this subsection for any taxable year shall be made not later than two years after the date on which the commissioner has begun collection activities with respect to the individual making the election. (d) (1) The portion of any deficiency on a joint return allocated to an individual electing under subsection (c) of this section shall be the amount which bears the same ratio to such deficiency as the net amount of items taken into account in computing the deficiency and allocable to the individual under this subdivision bears to the net amount of all items taken into account in computing the deficiency. (2) If a deficiency or portion thereof is attributable to the disallowance of a credit, and such item is allocated to one individual under subdivision (3) of this subsection, such deficiency or portion thereof shall be allocated to such individual. Any such item shall not be taken into account under subdivision (1) of this subsection. (3) Except as provided in subdivisions (4) and (5) of this subsection, any item giving rise to a deficiency on a joint return shall be allocated to individuals filing the return in the same manner as it would have been allocated if the individuals had filed separate returns for the taxable year. If the commissioner establishes that the allocation of any item is appropriate due to fraud of one or both individuals, the commissioner may provide for such allocation in a manner as prescribed in regulations adopted in accordance with chapter 54. (4) If an exemption under section 12-702 or a credit under section 12-703 would be disallowed in its entirety solely because a separate return is filed, such disallowance shall be disregarded and the item shall be computed as if a joint return had been filed and then allocated between the joint filers appropriately. (5) If the liability of a child of a taxpayer is included on a joint return, such liability shall be disregarded in computing the separate liability of either joint filer and such liability shall be allocated appropriately between the joint filers. (e) (1) The commissioner shall determine what relief, if any, is available to an electing individual under this section and shall mail notice of the proposed determination to such individual. Such notice shall set forth briefly the commissioner's findings of fact and the basis of the determination in each case decided in whole or in part adversely to such individual. Sixty days after the date on which it is mailed, a notice of proposed determination shall constitute a final determination except only for such amounts as to which such individual has filed a written protest with the commissioner in accordance with subdivision (2) of this subsection. (2) On or before the sixtieth day after the mailing of the proposed determination, such individual may file with the commissioner a written protest against the proposed determination in which such individual sets forth the grounds on which the protest is based. If a protest is filed, the commissioner shall reconsider the proposed determination and, if such individual has so requested, may grant or deny such individual or such individual's authorized representative an oral hearing. (3) The commissioner shall mail notice of the commissioner's determination to such individual, which notice shall set forth briefly the commissioner's findings of fact and the basis of decision in each case decided in whole or in part adversely to such individual. (4) The action of the commissioner on such individual's protest shall be final upon the expiration of one month from the date on which the commissioner mails notice of the commissioner's action to such individual unless within such period such individual seeks judicial review of the commissioner's determination pursuant to section 12-730. (f) Under procedures prescribed by the commissioner, if taking into account all the facts and circumstances, it is inequitable to hold such individual liable for any unpaid tax or any deficiency, or any portion of such unpaid tax or deficiency, and relief is not otherwise available to such individual under this section, the commissioner may relieve such individual of such liability. (g) The commissioner may adopt regulations, in accordance with chapter 54, as are necessary to carry out the provisions of this section, including regulations providing the opportunity for an individual to have notice of, and an opportunity to participate in, any administrative proceeding with respect to an election made under this section by the other individual filing the joint return. (h) The provisions of this section shall be applicable with respect to any liability arising after May 27, 1999, and any liability arising on or before May 27, 1999, if such liability remains unpaid as of said date, provided the two-year period to make an election under subsection (b) or (c) of this section shall not expire before the date that is two years after the date of the first collection activity after May 27, 1999. (P.A. 99-48, S. 4, 10; P.A. 00-230, S. 12; June Sp. Sess. P.A. 15-5, S. 124, 125.) History: P.A. 99-48 effective May 27, 1999; P.A. 00-230 made technical changes in Subsec. (a); June Sp. Sess. P.A. 15-5 amended Subsec. (a) to allow individual who made joint return to elect relief under Subsec. (f) even if not eligible for relief under Subsec. (b) or (c), amended Subsec. (f) to make a technical change, amended Subsec. (g) to make regulations permissive, rather than mandatory, and amended Subsec. (h) to add reference to Subsec. (b) or (c) re two-year period to make an election, effective June 30, 2015.

12-704. Credits for income taxes paid to other states. (a)(1) Any resident or part-year resident of this state shall be allowed a credit against the tax otherwise due under this chapter in the amount of any income tax imposed on such resident or part-year resident for the taxable year by another state of the United States or a political subdivision thereof or the District of Columbia on income derived from sources therein and which is also subject to tax under this chapter. (2) In the case of a resident, the credit provided under this section shall not exceed the proportion of the tax otherwise due under this chapter that the amount of the taxpayer's Connecticut adjusted gross income derived from or connected with sources in the other taxing jurisdiction bears to such taxpayer's Connecticut adjusted gross income under this chapter. The provisions of this section shall also apply to resident trusts and estates and, wherever reference is made in this section to residents of this state, such reference shall be construed to include resident trusts and estates. (3) In the case of a part-year resident, the credit provided under this section shall not exceed the proportion of the tax otherwise due during the period of residency under this chapter that the amount of the taxpayer's Connecticut adjusted gross income derived from or connected with sources in the other jurisdiction during the period of residency bears to such taxpayer's Connecticut adjusted gross income during the period of residency under this chapter. The provisions of this section shall also apply to part-year resident trusts and, wherever reference is made in this section to part-year residents of this state, such reference shall be construed to include part-year resident trusts. (4) The allowance of the credit provided under this section shall not reduce the tax otherwise due under this chapter to an amount less than what would have been due if the income subject to taxation by such other jurisdiction were excluded from Connecticut adjusted gross income. (5) For purposes of this subsection, a tax on wages that is paid to another state of the United States or a political subdivision thereof or the District of Columbia by an employer on behalf of an employee and for which a credit is allowed by such other jurisdiction shall be considered an income tax and a comparable credit may be claimed by the resident or part-year resident, subject to the limitations set forth in this subsection, in the form and manner prescribed by the commissioner. (b) (1) (A) If, as a direct result of (i) the change to or correction of a taxpayer's income tax return filed with another state of the United States or a political subdivision thereof or the District of Columbia by the tax officers or other competent authority of such jurisdiction, or (ii) a taxpayer paying an assessment issued against the taxpayer by the tax officers or other competent authority of such jurisdiction for any taxable year for which the taxpayer has not filed an income tax return with such jurisdiction, the amount of tax of such other jurisdiction that the taxpayer is finally required to pay is different from the amount used to determine the credit allowed to any taxpayer under this section for any taxable year, the taxpayer shall provide notice of such difference to the commissioner by filing, on or before the date that is ninety days after the final determination of such amount, an amended return under this chapter, and shall concede the accuracy of such determination or state wherein it is erroneous. The commissioner may redetermine, and the taxpayer shall be required to pay, the tax for any taxable year affected, regardless of any otherwise applicable statute of limitations. (B) If a taxpayer files an amended return under this subdivision as a direct result of the taxpayer paying an assessment as set forth in subparagraph (A)(ii) of this subdivision, the taxpayer shall not be eligible for a refund if the amended return is filed more than five years after the original due date of the taxpayer's Connecticut income tax return, even if such amended return is filed within the time prescribed under subdivision (2) of subsection (b) of section 12-732. (2) If, as a direct result of a taxpayer filing an amended income tax return with another state of the United States or a political subdivision thereof or the District of Columbia, the amount of tax of such other jurisdiction that the taxpayer is required to pay is different from the amount used to determine the credit allowed to any taxpayer under this section for any taxable year, the taxpayer shall provide notice of such difference to the commissioner by filing, on or before the date that is ninety days after the final determination is made on such amended return by the tax officers or other competent authority of such other jurisdiction, an amended return under this chapter and shall give such information as the commissioner may require. The commissioner shall treat any such amended return under this chapter reporting a tax overpayment as containing sufficient required information after proof of such final determination on such amended income tax return of such other jurisdiction by the tax officers or other competent authority of such other jurisdiction is submitted to the commissioner. The commissioner may redetermine, and the taxpayer shall be required to pay, the tax for any taxable year affected, regardless of any otherwise applicable statute of limitations. (3) The commissioner may by regulation prescribe such exceptions to the requirements of this subsection as he deems appropriate. (c) A taxpayer shall not be allowed credit under this section if such taxpayer has claimed or will claim a credit against the income tax imposed by such other jurisdiction for the tax paid or payable under this chapter. (d) Notwithstanding the provisions of subsection (c) of this section, if an individual is not domiciled in this state but maintains a permanent place of abode in this state and is in this state for an aggregate of more than one hundred eighty-three days of a taxable year and such individual is domiciled in another state of the United States, a political subdivision of such state, or the District of Columbia for the taxable year, such individual shall be allowed a credit under this section against the tax otherwise due under this chapter for income tax imposed by and paid to the qualifying jurisdiction in which such individual is domiciled on such individual's income from intangible personal property, to the extent such income is from property not employed in a business, trade, profession or occupation carried on in this state, and on such individual's income derived from or connected with sources within another state of the United States or the District of Columbia that does not impose an income tax on such income. This subsection shall apply only where the jurisdiction in which such individual is domiciled allows an income tax credit for the tax imposed by this state to an individual who is domiciled in this state for a taxable year but maintains a permanent place of abode in such jurisdiction and is in such jurisdiction for an aggregate of more than one hundred eighty-three days of the taxable year that is analogous to that provided in this subsection.

(a)(1) Each employer, as defined in section 12-707, maintaining an office or transacting business within this state and making payment of any wages taxable under this chapter to a resident or nonresident individual shall deduct and withhold from such wages for each payroll period a tax computed in such manner as to result, so far as practicable, in withholding from the employee's wages during each calendar year an amount substantially equivalent to the tax reasonably estimated to be due from the employee under this chapter with respect to the amount of such wages during the calendar year. The method of determining the amount to be withheld shall be prescribed by regulations of the Commissioner of Revenue Services adopted in accordance with chapter 54. (2) (A) Except as provided in subparagraph (B) of this subdivision, each payer, as defined in section 12-707, of distributions from a profit-sharing plan, a stock bonus, a deferred compensation plan, an individual retirement arrangement, an endowment or a life insurance contract, or of pension payments or annuity distributions, that maintains an office or transacts business within this state and makes payment of any amounts taxable under this chapter to a resident individual, shall, upon request by such individual, deduct and withhold an amount from the taxable portion of any such distribution. Such request and the determination of the amount to be withheld shall be made in accordance with regulations promulgated by the commissioner for pension payments and annuity distributions. (B) (i) For the period commencing July 1, 2025, and ending December 31, 2026, the withholding requirement for a lump sum payment under clause (ii) of this subparagraph shall not apply, except that if a payee has requested an amount to be withheld from such distribution, the payer shall withhold such amount. (ii) With respect to a lump sum distribution, if a payee does not make a request to have an amount withheld from such distribution, the payer shall withhold from the taxable portion of the distribution at the highest marginal rate, except that no withholding shall be required if (I) any portion of the lump sum distribution was previously subject to tax, or (II) the lump sum distribution is a rollover that is effected as a direct trustee-to-trustee transfer or as a direct rollover in the form of a check made payable to another qualified account. (iii) For purposes of this subparagraph, “lump sum distribution” means a payment from a payer to a resident payee of an amount exceeding fifty per cent of such resident payee's entire account balance or more than five thousand dollars, whichever is less, exclusive of any other tax withholding and any administrative charges and fees. (3) In no event shall the requirements of this subsection result in nonpayment of any distribution to a resident individual. For the calendar year ending December 31, 2018, no taxpayer shall be assessed interest by the commissioner pursuant to section 12-722 solely on the basis of a payer's failure to comply with the provisions of this subsection. (b) The commissioner may, if such action is deemed necessary for the protection of the revenue and under such regulations as the commissioner may adopt in accordance with the provisions of chapter 54, require persons other than employers and payers (1) to deduct and withhold taxes from payments made by such persons to residents of this state, nonresidents and part-year residents, (2) to file a withholding return as prescribed by the commissioner, and (3) to pay over to the commissioner, or to a depositary designated by the commissioner, the taxes so required to be deducted and withheld, in accordance with a schedule established in such regulations. (c) The commissioner may adopt regulations providing for withholding from (1) remuneration for services performed by an employee for his or her employer that does not constitute wages, (2) wages paid to an employee by an employer not maintaining an office or transacting business within this state, or (3) any other type of payment with respect to which the commissioner finds that withholding would be appropriate under the provisions of this chapter if the employer and the employee, or, in the case of any other type of payment, the person making and the person receiving such payment, agree to such withholding. Such agreement shall be made in such form and manner as the commissioner may prescribe by regulations adopted in accordance with the provisions of chapter 54. For purposes of this chapter, remuneration, wages or other payments with respect to which such an agreement is made shall be regarded as if they were wages paid to an employee by an employer maintaining an office or transacting business within this state to the extent that such remuneration or wages are paid or other payments are made during the period for which the agreement is in effect.

Such agreements may provide for recognition of anticipated tax credits in determining the amounts to be withheld and, under regulations prescribed in accordance with the provisions of chapter 54 by said commissioner, may relieve employers in this state from withholding income tax on wages and salaries paid to nonresident employees.

Conn. Gen. Stat. § 12-707 Payment to commissioner of taxes withheld by employers, payers or purchasers of a business. Security.

12-707. Payment to commissioner of taxes withheld by employers, payers or purchasers of a business. Security. (a)(1) Each employer required to deduct and withhold tax under this chapter from the wages of employees shall be liable for such tax and shall file a withholding return as prescribed by the Commissioner of Revenue Services and pay over to the commissioner, or to a depositary designated by the commissioner, the taxes so required to be deducted and withheld at the times specified in subsection (b) of this section. (2) Each payer shall deduct and withhold tax under this chapter from the nonpayroll amounts of payees, shall be liable for such tax and shall file a withholding return as prescribed by the commissioner and pay over to the commissioner, or to a depository designated by the commissioner, the taxes so required to be deducted and withheld at the times specified in subsection (b) of this section. (b) (1) (A) With respect to the tax required to be deducted and withheld under this chapter from wages paid during any calendar year beginning on or after January 1, 2005, and in accordance with an annual determination described in subdivision (2) of this subsection, each employer shall be either a weekly remitter, monthly remitter or quarterly remitter for the calendar year.

(2) (A) The annual determination for an employer required to deduct and withhold tax under this chapter shall be based on the employer's reported liability for the tax required to be deducted and withheld under this chapter during the twelve-month look-back period, provided, if any employer fails timely to file one or more required withholding tax returns for the four quarterly periods within the twelve-month look-back period, the commissioner may base the annual determination for the employer on any information available to the commissioner. If an employer's reported liability for the tax required to be deducted and withheld under this chapter during the twelve-month look-back period was more than ten thousand dollars, the employer is a weekly remitter for the calendar year next succeeding such twelve-month period. If an employer's reported liability for the tax required to be deducted and withheld under this chapter during the twelve-month look-back period was more than two thousand dollars but not more than ten thousand dollars, the employer is a monthly remitter for the calendar year next succeeding such twelve-month period. If an employer's reported liability for the tax required to be deducted and withheld under this chapter during the twelve-month look-back period was two thousand dollars or less, the employer is a quarterly remitter for the calendar year next succeeding such twelve-month period. Notwithstanding any provision of this section, if an employer is a seasonal employer, the annual determination shall be based on the seasonal employer's reported liability for the tax required to be deducted and withheld under this chapter during the twelve-month look-back period multiplied by a fraction, the numerator of which is four, and the denominator of which is the number of quarterly periods during such twelve-month period that the employer paid wages to employees.

If a payer's reported liability for the tax required to be deducted and withheld under this chapter during the look-back calendar year was more than ten thousand dollars, the payer is a weekly remitter for the calendar year for which the annual determination is being made. If a payer's reported liability for the tax required to be deducted and withheld under this chapter during the look-back calendar year was more than two thousand dollars but not more than ten thousand dollars, the payer is a monthly remitter for the calendar year for which the annual determination is being made. If a payer's reported liability for the tax required to be deducted and withheld under this chapter during the look-back calendar year was two thousand dollars or less, the payer is a quarterly remitter for the calendar year for which the annual determination is being made.

(d) The amount of tax required to be deducted and withheld and paid over to the commissioner under this chapter, when so deducted and withheld, shall be held to be a special fund in trust for the state. No employee or other person shall have any right of action against the employer with respect to any moneys deducted and withheld from wages and paid over to the commissioner in compliance or in intended compliance with this chapter. (e) (1) If an employer required to deduct and withhold tax under this chapter from the wages of employees and to pay over to the commissioner the taxes so required to be deducted and withheld sells out the employer's business or stock of goods or quits the employer's business, such employer's successors or assigns shall withhold a sufficient portion of the purchase price to cover the amount of such taxes, and any interest and penalties thereon, due and unpaid, as of the time of such sale or quitting of the business, until the employer produces a receipt from the commissioner showing that the taxes, interest and penalties have been paid or a certificate indicating that no such taxes are due. (2) If the purchaser of a business or stock of goods fails to withhold a portion of the purchase price as required, the purchaser shall be personally liable for the payment of the amount required to be withheld by the purchaser, to the extent of the purchase price, valued in money. Not later than sixty days after the latest of the dates specified in subdivision (3) of this subsection, the commissioner shall either issue a certificate indicating that no taxes are due or mail notice to the purchaser in the manner provided in section 12-728 of the amount that must be paid as a condition of issuing the certificate. Failure of the commissioner to mail the notice shall release the purchaser from any further obligation to withhold a portion of the purchase price as provided in this subsection. The period within which the obligation of the successor may be enforced shall begin when the employer sells out the employer's business or stock of goods or quits the employer's business or when the assessment against the employer becomes final, whichever event occurs later. (3) For purposes of subdivision (2) of this subsection, the latest of the following dates shall apply: (A) The date that the commissioner receives a written request from the purchaser for a certificate; (B) The date of the sale or quitting of the business; or (C) The date that the employer's records are made available to the commissioner for audit. (f) (1) Whenever any employer or payer required to deduct and withhold tax under this chapter (A) owes such taxes, which taxes have been finally due and payable for a period of ninety days or longer and for which any administrative or judicial remedies, or both, have been exhausted or have lapsed, or (B) has failed to file one or more withholding tax returns required under this chapter, the commissioner may require any employer or payer to deposit with the commissioner such security as the commissioner determines necessary, provided the amount of such security shall not be greater than six times the employer's or payer's estimated liability for the prior twelve-month period or the employer's or payer's liability for the next twelve-month period, determined in such manner as the commissioner deems proper. The commissioner may increase or decrease the amount of the security, subject to the limitations in this subsection. (2) The commissioner may sell the security at public auction if it becomes necessary to do so to recover any tax or amount required to be collected or any interest or penalty due. Notice of such sale may be served personally or by mail upon the person that deposited the security.

Conn. Gen. Stat. § 12-708 Determination of taxable year and method of accounting changes.

12-708. Determination of taxable year and method of accounting changes. (a) For purposes of the tax imposed under this chapter, a taxpayer's taxable year shall be the same as such taxpayer's taxable year for federal income tax purposes and a taxpayer's method of accounting shall be the same as such taxpayer's method of accounting for federal income tax purposes. (b) If a taxpayer's taxable year is changed for federal income tax purposes, the taxable year for purposes of the tax under this chapter shall be similarly changed. If a change in taxable year results in a taxable period of less than twelve months, the exemption allowed under section 12-702 shall be prorated under regulations adopted by the Commissioner of Revenue Services in accordance with chapter 54. (c) If no method of accounting has been regularly used by the taxpayer, Connecticut taxable income shall be computed under such method that in the opinion of the commissioner, fairly reflects income. If a taxpayer's method of accounting is changed for federal income tax purposes, the method of accounting for purposes of this chapter shall similarly be changed. (d) In computing a taxpayer's Connecticut taxable income for any taxable year under a method of accounting different from the method under which the taxpayer's Connecticut taxable income for the previous year was computed, there shall be taken into account those adjustments which are determined, under regulations adopted by the commissioner, to be necessary solely by reason of the change in order to prevent amounts from being duplicated or omitted. (e) If a taxpayer's method of accounting is changed, other than from an accrual to an installment method, any additional tax which results from adjustments determined to be necessary solely by reason of the change shall not be greater than if such adjustments were ratably allocated and included for the taxable year of the change and the preceding taxable years, not in excess of two years, during which the taxpayer used the method of accounting from which the change is made. If a taxpayer's method of accounting is changed from an accrual to an installment method, any additional tax for the year of such change of method and for any subsequent year which is attributable to the receipt of installment payments properly accrued in a prior year, shall be reduced by the portion of tax for any prior taxable year attributable to the accrual of such installment payments. (June Sp. Sess. P.A. 91-3, S. 59, 168.) History: June Sp. Sess. P.A. 91-3, S. 59, effective August 22, 1991, and applicable to taxable years of taxpayers commencing on or after January 1, 1991.

Conn. Gen. Stat. § 12-711 Determination of income, gain, loss and deduction derived from or connected with sources within this state.

12-711. Determination of income, gain, loss and deduction derived from or connected with sources within this state. (a) The income of a nonresident natural person derived from or connected with sources within this state shall be the sum of the net amount of items of income, gain, loss and deduction entering into his or her Connecticut adjusted gross income for the taxable year, derived from or connected with sources within this state, including: (1) His or her distributive share of partnership income, gain, loss and deduction, determined under section 12-712; (2) his or her pro rata share of S corporation income, gain, loss and deduction, determined under section 12-712; (3) his or her share of estate or trust income, gain, loss and deduction, determined under section 12-714; and (4) his or her compensation from nonqualified deferred compensation plans attributable to services performed within this state, including, but not limited to, compensation required to be included in federal gross income under Section 457A of the Internal Revenue Code. (b) (1) Items of income, gain, loss and deduction derived from or connected with sources within this state shall be those items attributable to: (A) The ownership or disposition of any interest in real property in this state or tangible personal property in this state, as determined pursuant to subdivision (6) of this subsection; (B) a business, trade, profession or occupation carried on in this state; (C) in the case of a shareholder of an S corporation, the ownership of shares issued by such corporation, to the extent determined under section 12-712; or (D) winnings from a wager placed in a lottery conducted by the Connecticut Lottery Corporation, if the proceeds from such wager are required, under the Internal Revenue Code or regulations adopted thereunder, to be reported by the Connecticut Lottery Corporation to the Internal Revenue Service. (2) (A) Before, on and after December 29, 2015, income from a business, trade, profession or occupation carried on in this state includes, but is not limited to, compensation paid to a nonresident natural person for rendering personal services as an employee in this state. For taxable years commencing on or after January 1, 2016, compensation for personal services rendered in this state by such nonresident employee who is present in this state for not more than fifteen days during a taxable year shall not constitute income derived from sources within this state. If a nonresident employee is present in this state for more than fifteen days during a taxable year, all compensation the employee receives for the rendering of all personal services in this state during the taxable year shall constitute income derived from sources within this state during the taxable year. (B) For purposes of determining whether a nonresident employee is “present in this state” under subparagraph (A) of this subdivision, presence in this state for any part of a day constitutes being present in this state for that entire day unless such presence is solely for the purpose of transit through this state. The provisions of this subparagraph shall not apply to subsection (c) of this section or to any other provision of law unless expressly provided. (C) For purposes of determining the compensation derived from or connected with sources within this state, a nonresident natural person shall include income from days worked outside this state for such person's convenience if such person's state of domicile uses a similar test. (D) The provisions of this subdivision shall not apply to sources of income from a business, trade, profession, or occupation carried on in this state other than compensation for personal services rendered by a nonresident employee, and shall not apply to sources of income derived by an athlete, entertainer or performing artist, including, but not limited to, a member of an athletic team. (3) Income from intangible personal property, including annuities, dividends, interest and gains from the disposition of intangible personal property, shall constitute income derived from sources within this state only to the extent that such income is from (A) property employed in a business, trade, profession or occupation carried on in this state, or (B) winnings from a wager placed in a lottery conducted by the Connecticut Lottery Corporation, if the proceeds from such wager are required, under the Internal Revenue Code or regulations adopted thereunder, to be reported by the Connecticut Lottery Corporation to the Internal Revenue Service. (4) Deductions with respect to capital losses and net operating losses shall be based solely on income, gain, loss and deduction derived from or connected with sources within this state, under regulations adopted by the commissioner, but otherwise shall be determined in the same manner as the corresponding federal deductions. (5) Income directly or indirectly derived by an athlete, entertainer or performing artist, including, but not limited to, a member of an athletic team, from closed-circuit and cable television transmissions of an event, other than events occurring on a regularly scheduled basis, taking place within this state as a result of the rendition of services by such athlete, entertainer or performing artist shall constitute income derived from or connected with sources within this state only to the extent that such transmissions were received or exhibited within this state. (6) For purposes of subparagraph (A) of subdivision (1) of this subsection, “real property in this state” includes an interest in an entity, and “entity” means a partnership, limited liability company or S corporation that owns, directly or indirectly, real property that is located within this state and has a fair market value that equals or exceeds fifty per cent of all the assets of the entity on the date of sale or disposition by a nonresident natural person of such person's interest in the entity. Only those assets that the entity owned, directly or indirectly, for at least two years prior to the date of the sale or disposition of the person's interest in the entity shall be used in determining the fair market value of all the assets of the entity on the date of such sale or disposition. The gain or loss derived from Connecticut sources from such person's sale or disposition of an interest in such entity is the total gain or loss for federal income tax purposes from such sale or disposition multiplied by a fraction, the numerator of which is the fair market value of all real property located in this state owned, directly or indirectly, by the entity on the date of such sale or disposition, and the denominator of which is the fair market value of all the assets of the entity on the date of such sale or disposition. (c) (1) If a business, trade, profession or occupation is carried on partly within and partly without this state, as determined under rules or regulations of the commissioner, the items of income, gain, loss and deduction derived from or connected with sources within this state shall be determined by apportionment under such rules or regulations and the provisions of this subsection. (2) The proportion of the net amount of the items of income, gain, loss and deduction attributable to the activities of the business, trade, profession or occupation carried on in this state shall be determined by multiplying the net amount of the items of income, gain, loss and deduction of the business, trade, profession or occupation by the gross income percentage. The gross income percentage shall be computed by dividing the gross receipts from sales earned within this state by the total gross receipts from sales, whether earned within or without this state. For the purposes of this subdivision: (A) Gross receipts from sales of tangible personal property are considered to be earned within this state when the property is delivered or shipped to a purchaser within this state, regardless of the F.O.B. point or other conditions of the sale. (B) Gross receipts from sales of services are considered to be earned within this state if the market for the services is in this state. The taxpayer's market for services is in this state if and to the extent the service is used at a location in this state. (C) Gross receipts from the rental, lease or license of tangible personal property are considered to be earned within this state if and to the extent such property is situated in this state. (D) Gross receipts from the rental, lease or license of intangible property are considered to be earned within this state if and to the extent such property is used in this state. Intangible property utilized in marketing a good or service to a consumer is used in this state if that good or service is purchased by a consumer in this state. (E) Gross receipts from the sale or other disposition of tangible personal property or intangible property are excluded from the gross income percentage if such property is not held by the taxpayer primarily for sale to customers in the ordinary course of the taxpayer's trade or business. (F) Gross receipts from the sale, rental, lease or license of real property are excluded from the gross income percentage. (G) Gross receipts, other than those receipts described in subparagraphs (A) to (F), inclusive, of this subdivision, are considered to be earned within this state to the extent the taxpayer's market for the sales is in this state. (H) If a taxpayer concludes that it cannot reasonably determine where its gross receipts are earned in accordance with subparagraphs (A) to (G), inclusive, of this subdivision, such taxpayer may petition the commissioner for approval to use a methodology that reasonably approximates the method for determining where such receipts are earned provided for in this subdivision. Any such petition shall be submitted not later than sixty days prior to the due date of the return for the first taxable year to which the petition applies, determined with regard to any extension of time for filing such return. The commissioner shall grant or deny such petition before such due date. (d) Compensation paid by the United States for active service in the armed forces of the United States, performed by an individual not domiciled in this state, shall not constitute income derived from sources within this state. (e) If a husband and wife determine their federal income tax on a joint return but are required to determine their Connecticut income taxes separately, they shall determine their incomes derived from or connected with sources within this state separately as if their federal adjusted gross incomes had been determined separately. (f) Any nonresident, other than a dealer holding property primarily for sale to customers in the ordinary course of his trade or business, shall not be deemed to carry on a trade, business, profession or occupation in this state solely by reason of the purchase or sale of intangible property or the purchase, sale or writing of stock option contracts, or both, for his own account.

Conn. Gen. Stat. § 12-711a Repayment of income by taxpayer.

12-711a. Repayment of income by taxpayer. (a)(1) If an item of income was included in the Connecticut adjusted gross income of an individual for a preceding taxable year or years because it appeared that the individual had an unrestricted right to such item, and, based on the repayment of such item by such individual during the taxable year, such individual properly determines his or her federal income tax liability for the taxable year under Section 1341(a)(4) or (5) of the Internal Revenue Code, then the tax imposed by this chapter for the taxable year on such individual shall be an amount equal to (A) the tax for the taxable year computed without regard to this section, minus (B) the decrease in tax under this chapter for the preceding taxable year or years which would result solely from the exclusion of such item or portion thereof from the Connecticut adjusted gross income of such individual for such preceding taxable year or years. This section shall not apply if such repayment is properly deductible in determining the individual's federal adjusted gross income for the taxable year, and such individual properly determines his or her federal income tax liability for the taxable year under Section 1341(a)(4) of the Internal Revenue Code by deducting such repayment. (2) In determining the decrease in tax under this chapter for the preceding taxable year or years which would result solely from the exclusion of such item or portion thereof from the Connecticut adjusted gross income of such individual for such preceding taxable year or years, any item excluded from the Connecticut adjusted gross income of an individual for a preceding year or years in which such individual was a nonresident individual or part-year resident individual, shall, to the extent that such item is derived from or connected with sources within this state, be excluded from Connecticut adjusted gross income derived from or connected with sources within this state for such preceding year or years. (3) If the decrease in tax under this chapter for the preceding taxable year or years which would result solely from the exclusion of such item or portion thereof from the Connecticut adjusted gross income of such individual for such preceding taxable year or years exceeds the tax for the taxable year computed without regard to this section, such excess shall be considered to be a payment of tax on the last day prescribed under this chapter for the payment of tax for the taxable year, and, subject to the provisions of sections 12-35f, 12-739 and 12-742, shall be refunded or credited in the same manner as if it were an overpayment for such taxable year. (b) If an individual properly determines his or her liability for the tax imposed by this chapter for the taxable year under subsection (a) of this section, and properly determines his or her federal income tax liability for the taxable year under Section 1341(a)(4) of the Internal Revenue Code, then, in any case where the deduction under Section 1341(a)(4) of the Internal Revenue Code results in a net operating loss for federal income tax purposes, no claim for refund shall be allowable by the commissioner for an overpayment of the tax imposed by this chapter for a preceding taxable year or years to the extent attributable to such loss being carried back to such year or years. (P.A. 00-174, S. 46, 83.)

(c) (1) The character of partnership or corporation items for a nonresident partner or S corporation shareholder shall be determined in accordance with section 12-715. (2) The effect of a special provision in a partnership agreement, other than a provision referred to in subsection (b) of this section, having the principal purpose of avoidance or evasion of tax under this chapter shall be determined under subsection (c) of section 12-715.

12-713. Determination of income within this state of nonresident trusts and estates. (a) The income derived from or connected with sources within this state of a nonresident estate or trust shall be determined as follows: (1) There shall be determined its share of income, gain, loss and deduction from Connecticut sources under section 12-714. (2) There shall be added or subtracted, as the case may be, the amount derived from or connected with Connecticut sources of any income, gain, loss and deduction which would be included in the determination of federal adjusted gross income if the estate or trust were an individual and which is recognized for federal income tax purposes but excluded from the definition of federal distributable net income of the estate or trust. In the case of a trust, there shall be added the amount of any includable gain, reduced by any deductions properly allocable thereto, upon which tax is imposed for the taxable year pursuant to Section 644 of the Internal Revenue Code. The source of such income, gain, loss and deduction shall be determined in accordance with the applicable rules of section 12-711 as in the case of a nonresident individual. (b) Deductions with respect to capital losses and net operating losses shall be based solely on income, gains, losses and deductions derived from or connected with sources within this state, under rules or regulations of the commissioner, but otherwise determined in the same manner as the corresponding federal deductions.

Conn. Gen. Stat. § 12-714 Determination of share of nonresident estate or trust and nonresident beneficiary in income within this state.

12-714. Determination of share of nonresident estate or trust and nonresident beneficiary in income within this state. (a) The share of a nonresident estate or trust under subdivision (1) of subsection (a) of section 12-713, and the share of a nonresident beneficiary of any estate or trust under subsection (a) of section 12-711, in estate or trust income, gain, loss and deduction derived from or connected with sources within this state shall be determined as follows: (1) There shall be determined the items of income, gain, loss and deduction which are derived from or connected with sources within this state, which would be included in the determination of federal adjusted gross income if the estate or trust were an individual and which enter into the definition of federal distributable net income of the estate or trust for the taxable year, including any such items from another estate or trust of which the subject estate or trust is a beneficiary. Such determination of source shall be made in accordance with the provisions of section 12-711 in the same manner as for a nonresident individual. (2) The amounts determined under subdivision (1) of this subsection shall be allocated among the estate or trust and its beneficiaries, including, solely for the purpose of this allocation, resident beneficiaries, in proportion to their respective shares of federal distributable net income. (3) The amount allocated under subdivision (2) of this section shall have the same character under this chapter as for federal income tax purposes. Where an item entering into the computation of such amounts is not characterized for federal income tax purposes, it shall have the same character as if it were realized directly from the source from which it was realized by the estate or trust, or as if it were incurred in the same manner as it was incurred by the estate or trust. (b) (1) If the estate or trust has no federal distributable net income for the taxable year, the share of each beneficiary, including, solely for the purpose of this allocation, resident beneficiaries, in the net amount determined under subdivision (1) of subsection (a) of this section shall be in proportion to his share of the estate or trust income for such year, under local law or the governing instrument, which is required to be distributed currently and any other amounts of such income distributed in such year. Any balance of such net amount shall be allocated to the estate or trust. (2) The commissioner may by regulation establish such other method or methods of determining the respective shares of the beneficiaries and of the estate or trust in its income derived from sources within this state as may be appropriate and equitable. Such method may be used by the fiduciary in his discretion whenever the allocation of such respective shares under subsection (a) of this section or subdivision (1) of this subsection would result in an inequity which is substantial in amount.

(a) In determining the Connecticut adjusted gross income of a resident partner of a partnership or a resident shareholder of an S corporation, any modification described in section 12-701 which relates to an item of partnership or S corporation income, gain, loss or deduction shall be made in accordance with the partner's distributive share or a shareholder's pro rata share, for federal income tax purposes, of the item to which the modification relates. Where a partner's distributive share or a shareholder's pro rata share of any such item is not required to be taken into account separately for federal income tax purposes, the partner's or shareholder's share of such item shall be determined in accordance with his share, for federal income tax purposes, of partnership or S corporation taxable income or loss generally. (b) Each item of partnership and S corporation income, gain, loss or deduction shall have the same character for a partner or shareholder under this chapter as for federal income tax purposes. Where an item is not characterized for federal income tax purposes, it shall have the same character for a partner or shareholder as if it were realized directly from the source from which it was realized by the partnership or S corporation or as if it was incurred in the same manner as it was incurred by the partnership or S corporation. (c) Where a partner's distributive share of an item of partnership income, gain, loss or deduction is determined for federal income tax purposes by special provision in the partnership agreement with respect to such item, and where the principal purpose of such provision is the avoidance or evasion of tax under this chapter, the partner's distributive share of such item, and any modification required with respect thereto, shall be determined as if the partnership agreement made no special provision with respect to such item.

Any balance of the Connecticut fiduciary adjustment shall be allocated to the estate or trust. (b) The commissioner may, by regulation establish such other method or methods of determining to whom the items comprising the fiduciary adjustment shall be attributed as may be appropriate and equitable.

(3) No item of income, gain, loss or deduction which is accrued under this subsection shall be taken into account in determining Connecticut adjusted gross income or income derived from or connected with sources within this state for any subsequent taxable period. (4) The accruals otherwise required under this subsection shall not be required if the individual files with the commissioner a bond or other security acceptable to the commissioner, conditioned upon the inclusion of amounts accruable under this subsection in Connecticut adjusted gross income or income derived from or connected with sources within this state for one or more subsequent taxable years as if the individual had not changed his resident status. (5) If a trust changes its status from resident to nonresident or from nonresident to resident, the provisions of subdivisions (1) to (4), inclusive, of this subsection shall apply, except that the term “individual” shall be read as “trust”, reference to “items of income, gain, loss or deduction” shall mean the trust's share of such items determined in accordance with the methods of allocation set forth in section 12-714, reference to “gain” shall include any modification for includable gain under subdivision (9) of subsection (a) of section 12-701 and federal adjusted gross income shall be determined as if the trust were an individual.

The commissioner may make any deficiency assessment against, at the commissioner's sole discretion, either the partnership or the partner, provided any such assessment against the partner shall be limited to the partner's share thereof. Except as otherwise provided in section 12-733, any such assessment shall be made not later than three years after the partnership's annual return pursuant to section 12-726 is filed.

The commissioner may make any deficiency assessment that is related to the partner's share of partnership items against either, in the commissioner's sole discretion, the partnership or the partner.

(D) If a member of a pass-through entity, referred to in this subparagraph as an “upper-tier pass-through entity”, is itself a pass-through entity, the member, referred to in this subparagraph as a “lower-tier pass-through entity”, shall be subject to the same requirements to make payment, on behalf of its members, of the income tax imposed on those members pursuant to this chapter that apply to the upper-tier pass-through entity under this subdivision. The department shall apply the income tax paid by the upper-tier pass-through entity, on behalf of the lower-tier pass-through entity, to the income tax required to paid by the lower-tier pass-through entity, on behalf of its members.

In no event shall the payment with respect to any nonresident shareholder be less than zero. (2) (A) Any payment under this subdivision shall be in an amount equal to the highest marginal tax rate in effect under section 12-700 for the taxable year multiplied by the subject shareholder's pro rata share of (i) such S corporation's separately and nonseparately computed items, as described in Section 1366 of the Internal Revenue Code, to the extent derived from or connected with sources within this state, as determined under this chapter, and (ii) any modification described in section 12-701 which relates to an item of such S corporation's income, gain, loss or deduction, to the extent derived from or connected with sources within this state, as determined under this chapter.

(2) If a professional athletic team is required to file a composite return pursuant to this subsection, the commissioner may, if he determines that the enforcement of this chapter would not be adversely affected, require such team, in lieu of deducting and withholding Connecticut income tax as may otherwise be required under section 12-705, to make payment to the commissioner of tax, estimated tax, additions to tax, interest and penalties otherwise required to be paid to the commissioner by such qualifying nonresident members.

Such amount shall bear interest at the rate of one per cent per month or fraction thereof from the date when the original tax became due and payable.

In the case of a joint return, the notice of deficiency may be a single joint notice except that if the commissioner is notified by either spouse that separate residences have been established he shall mail joint notices to each spouse.

If the amount specified in the notice of jeopardy assessment is not paid on or before the tenth day after service of notice upon the person against whom such jeopardy assessment is made, the penalty and the interest provided in section 12-735 shall attach to the amount of the tax. (c) The person against whom the jeopardy assessment is made may file a written protest with the commissioner on or before the tenth day after the service upon such person of notice of the jeopardy assessment.

At any time thereafter in respect to the whole or any part of the amount covered by such bond, the person against whom a jeopardy assessment has been made may waive such stay, and if, as the result of such waiver, any part of the amount covered by the bond is paid, the bond shall, at the request of such person, be proportionately reduced. (d) Notice of the commissioner's determination, following reconsideration of the jeopardy assessment, shall be served, personally or by mail, on the person against whom the jeopardy assessment was made, and such notice shall set forth the commissioner's findings of fact and the basis of decision in each case decided in whole or in part adversely to such person. (e) The determination of the commissioner following reconsideration of the jeopardy assessment, shall be final upon the expiration of one month from the date on which notice thereof is served, personally or by mail, on the person against whom the jeopardy assessment was made unless within such period the taxpayer seeks judicial review of the commissioner's determination under section 12-730.

Notwithstanding the provisions of chapter 54 to the contrary, any taxpayer aggrieved because of any determination or disallowance by the commissioner under section 12-729, 12-729a or 12-732 may, not later than thirty days after notice of the commissioner's determination or disallowance is mailed to the taxpayer, take an appeal therefrom to the superior court for the judicial district of New Britain, which shall be accompanied by a citation to the commissioner to appear before said court. Such citation shall be signed by the same authority, and such appeal shall be returnable at the same time and served and returned in the same manner, as is required in case of a summons in a civil action. The authority issuing the citation shall take from the appellant a bond or recognizance to the state of Connecticut, with surety to prosecute the appeal to effect and to comply with the orders and decrees of the court in the premises. Such appeals shall be preferred cases, to be heard unless cause appears to the contrary, at the first session by the court or by a committee appointed by it. Said court may grant such relief as may be equitable and, if such tax has been paid prior to the granting of such relief, may order the Treasurer to pay the amount of such relief, with interest at the rate of two-thirds of one per cent per month or fraction thereof, to the aggrieved taxpayer. If the appeal has been taken without probable cause, the court may charge double or triple costs, as the case demands, and upon all such appeals which may be denied, costs may be taxed against the appellant at the discretion of the court but no costs shall be taxed against the state.

Conn. Gen. Stat. § 12-732 Refunds.

12-732. Refunds. (a)(1) If any tax has been overpaid, the taxpayer may file a claim for refund in writing with the commissioner within three years from the due date for which such overpayment was made, stating the specific grounds upon which the claim is founded, provided if the commissioner has extended the time for the filing of an income tax return by the taxpayer, the taxpayer may file a claim for refund within three years after the date on which the income tax return is filed by the taxpayer or within three years after the extended due date of the income tax return, whichever is earlier. Not later than ninety days following receipt of such claim for refund the commissioner shall determine whether such claim is valid and, if so, said commissioner shall notify the State Comptroller of the amount of such refund and the State Comptroller shall draw an order on the State Treasurer in the amount thereof for payment to the taxpayer. For purposes of this section, a claim for refund that is filed before the last day prescribed by law or by a regulation adopted pursuant to law for the filing of an income tax return, determined without regard to any extension of time for filing, shall be deemed to be filed on such last day. To the amount of such refund, there shall be added interest at the rate of two-thirds of one per cent for each month or fraction thereof which elapses between (A) the ninetieth day following receipt by the commissioner of such claim for refund on a permitted form, containing the taxpayer's name, address and Social Security number or federal employer identification number, the required signature, and sufficient required information, whether on the return or on required attachments, to permit the mathematical verification of tax liability shown on the return, and (B) the date of notice by the commissioner that such refund is due. Failure to file a claim within the time prescribed in this section constitutes a waiver of any demand against the state on account of overpayment. If the commissioner determines that such claim is not valid, either in whole or in part, said commissioner shall mail notice of the disallowance in whole or in part of the claim to the claimant and such notice shall set forth briefly the commissioner's findings of fact and the basis of disallowance in each case decided in whole or in part adversely to the claimant. Sixty days after the date on which it is mailed, a notice of proposed disallowance shall constitute a final disallowance except only for such amounts as to which the claimant has filed, as provided in subdivision (2) of this subsection, a written protest with the commissioner. (2) On or before the sixtieth day after the mailing of the proposed disallowance, the claimant may file with the commissioner a written protest against the proposed disallowance in which the claimant sets forth the grounds on which the protest is based. If a protest is filed, the commissioner shall reconsider the proposed disallowance and, if the claimant has so requested, may grant or deny the claimant or the claimant's authorized representatives an oral hearing. (3) The commissioner shall mail notice of his determination to the claimant, which notice shall set forth briefly the commissioner's findings of fact and the basis of decision in each case decided in whole or in part adversely to the claimant. (4) The action of the commissioner on the claimant's protest shall be final upon the expiration of one month from the date on which he mails notice of his action to the claimant unless within such period the claimant seeks judicial review of the commissioner's determination pursuant to section 12-730. (b) (1) Notwithstanding the three-year limitation provided by subsection (a) of this section, if a taxpayer has timely complied with the requirements of subsection (b) of section 12-727, and, as a direct result of the change to or correction of the taxpayer's federal income tax return by the United States Internal Revenue Service or other competent authority, or as a direct result of a renegotiation of a contract or subcontract with the United States, the tax that has previously been reported to be due on a tax return under this chapter has been overpaid, or as a direct result of an amendment by the taxpayer of the taxpayer's federal income tax return, the tax that has previously been reported to be due on a tax return under this chapter has been overpaid, any claim for refund subsequently filed by such taxpayer will be deemed to be timely filed. (2) Notwithstanding the three-year limitation provided by subsection (a) of this section, if a taxpayer has timely complied with the requirements of subsection (b) of section 12-704 and as a direct result of (A) the change to or correction of taxpayer's income tax return by the tax officers or other competent authority of another state of the United States or a political subdivision thereof or the District of Columbia, the tax that has previously been reported to be due on a tax return under this chapter has been overpaid, (B) an amendment by the taxpayer of the taxpayer's income tax return to another state of the United States or a political subdivision thereof or the District of Columbia, the tax that has previously been reported to be due on a tax return under this chapter has been overpaid, or (C) a taxpayer paying an assessment issued against the taxpayer by the tax officers or other competent authority of another state of the United States or a political subdivision thereof or the District of Columbia for any taxable year for which the taxpayer has not filed an income tax return with such jurisdiction, the tax that has previously been reported to be due on a tax return under this chapter has been overpaid, any claim for refund subsequently filed by such taxpayer will be deemed to be timely filed.
