in effect

Conn. Gen. Stat. § 12-35 Duties of state collection agencies. Statute of limitations on collection by Commissioner.

12-35. Duties of state collection agencies. Statute of limitations on collection by Commissioner. (a)(1) Wherever used in this chapter, unless otherwise provided, “state collection agency” includes the Treasurer, the Commissioner of Revenue Services and any other state official, board or commission authorized by law to collect taxes payable to the state and any duly appointed deputy of any such official, board or commission; “tax” includes not only the principal of any tax but also all interest, penalties, fees and other charges added thereto by law; and “serving officer” includes any state marshal, constable or employee of such state collection agency designated for such purpose by a state collection agency and any person so designated by the Labor Commissioner. (2) Upon the failure of any person to pay any tax, except any tax under chapter 216, due the state within thirty days from its due date, the state collection agency charged by law with its collection shall add thereto such penalty or interest or both as are prescribed by law, provided, (A) if any statutory penalty is not specified, there may be added a penalty in the amount of ten per cent of the whole or such part of the principal of the tax as is unpaid or fifty dollars, whichever amount is greater, and (B) if any statutory interest is not specified, there shall be added interest at the rate of one per cent of the whole or such part of the principal of the tax as is unpaid for each month or fraction thereof, from the due date of such tax to the date of payment. (3) Upon the failure of any person to pay any tax, except any tax under chapter 216, due within thirty days of its due date, the state collection agency charged by law with the collection of such tax may make out and sign a warrant directed to any serving officer for distraint upon any property of such person found within the state, whether real or personal. An itemized bill shall be attached thereto, certified by the state collection agency issuing such warrant as a true statement of the amount due from such person. (A) Such warrant shall have the same force and effect as an execution issued pursuant to chapter 906. Such warrant may be levied on any real property or tangible or intangible personal property of such person, and sale made pursuant to such warrant in the same manner and with the same force and effect as a levy of sale pursuant to an execution. In addition thereto, if such warrant has been issued by the Commissioner of Revenue Services, the commissioner's deputy, the Labor Commissioner, the executive director of the Employment Security Division or any person in the Employment Security Division in a position equivalent to or higher than the position presently held by a revenue examiner four, such serving officer shall be authorized to place a keeper in any place of business and it shall be such keeper's duty to secure the income of such business for the state and, when it is in the best interest of the state, to force cessation of such business operation. In addition, the Attorney General may collect any such tax by civil action. Each serving officer so receiving a warrant shall make a return with respect to such warrant to the appropriate collection agency within a period of ten days following receipt of such warrant. (B) Each serving officer shall collect from such person, in addition to the amount shown on such warrant, such officer's fees and charges, which shall be twice those authorized by statute for serving officers, provided the minimum charge shall be five dollars and money collected pursuant to such warrant shall be first applied to the amount of any fees and charges of the serving officer. In the case of an employee of the state acting as a serving officer the fees and charges collected by such employee shall inure to the benefit of the state. (4) For the purposes of this subsection, “keeper” means a person who has been given authority by an officer authorized to serve a tax warrant to act in the state's interest to secure the income of a business for the state and, when it is in the best interest of the state, to force the cessation of such business's operation, upon the failure of such business to pay taxes owed to the state. (b) (1) Any such warrant on any intangible personal property of any person may be served by mailing a certified copy of such warrant by certified mail, return receipt requested, to any third person in possession of, or obligated with respect to, receivables, bank accounts, evidences of debt, securities, salaries, wages, commissions, compensation or other intangible personal property subject to such warrant, ordering such third person to forthwith deliver such property or pay the amount due or payable to the state collection agency that has made out such warrant, provided such warrant may be issued only after the state collection agency making out such warrant has notified the person owning such property, in writing, of its intention to issue such warrant. The notice of intent shall be: (A) Given in person; (B) left at the dwelling or usual place of business of such person; or (C) sent by certified mail, return receipt requested, to such person's last known address, not less than thirty days before the day the warrant is to be issued. (2) Any such warrant on any intangible personal property of any person may be served by electronic mail, facsimile machine or other electronic means on any third person in possession of, or obligated with respect to, receivables, bank accounts, evidences of debt, securities, salaries, wages, commissions, compensation or other intangible personal property subject to such warrant, ordering such third person to forthwith deliver such property or pay the amount due or payable to the state collection agency that has made out such warrant, provided such warrant may be issued only after the state collection agency making out such warrant has notified the person owning such property, in writing, of its intention to issue such warrant. The notice of intent shall be: (A) Given in person; (B) left at the dwelling or usual place of business of such person; or (C) sent by certified mail, return receipt requested, to such person's last-known address, not less than thirty days before the day the warrant is to be issued. Any such warrant for tax due may further include an order to such third person to continually deliver, during the one hundred eighty days immediately following the date of issuance of the warrant or until the tax is fully paid, whichever occurs earlier, all intangible personal property that is due and that becomes due to the person owing the tax. Except as otherwise provided in this subdivision, such warrant shall have the same force and effect as an execution issued pursuant to chapter 906. (c) (1) Except as provided in subdivision (3) of this subsection: (A) The Commissioner of Revenue Services may not collect a tax after ten years from the date the tax was reported on a return that was filed with the commissioner; and (B) If the commissioner makes an assessment of any tax within the statute of limitations applicable to the period for which such assessment was made, the commissioner may not collect such tax after ten years from the date such assessment became final. (2) Any taxes that remain unpaid after the applicable ten-year period shall be deemed abated as of the first day of the eleventh year succeeding the date the return was filed or the assessment became final, as applicable. (3) This subsection shall not apply to any taxes for which the commissioner has entered into an agreement under the provisions of section 12-2d or 12-2e or to any taxes that have been secured by the recording of a lien on the real property or personal property of a taxpayer.

(a) For purposes of this section: (1) “Taxpayer” means any person identified by a claimant state to the Commissioner of Revenue Services under this section as owing taxes to such claimant state, including, in the case of a refund of any tax imposed upon the income of individuals, the spouse of the taxpayer, where such taxpayer filed a joint return with such spouse; (2) “Claimant state” means any other state or the District of Columbia that extends a like comity for the collection of taxes owed to this state; (3) “Taxes” means any amount of tax imposed under the laws of the claimant state, including additions to tax for penalties and interest, which is finally due and payable to the claimant state, and with respect to which any administrative or judicial remedies, or both, have been exhausted or have lapsed, and which is legally enforceable under the laws of the claimant state, whether or not there is an outstanding judgment for such sum; (4) “Refund” means any taxpayer's claim to repayment of an overpayment of a tax determined by this state to be owed to the taxpayer by this state; and (5) “Tax officer” means a unit or official of a claimant state, or the duly authorized agent of such unit or official, charged with the imposition, assessment or collection of taxes of that state. (b) (1) Upon the request and certification of the tax officer of a claimant state to the Commissioner of Revenue Services that a taxpayer owes taxes to such claimant state, the commissioner may withhold all or a portion of any refund to which such taxpayer would otherwise be entitled and pay over such withheld amount to the claimant state in accordance with the provisions of this section. The commissioner shall not withhold a refund unless the laws of the claimant state allow the Commissioner of Revenue Services to certify that a taxpayer owes taxes to this state and to request the tax officer of the claimant state to withhold all or a portion of any refund to which such taxpayer would otherwise be entitled, and provide for the payment over of such withheld amount to this state. (2) Such certification shall include the full name and address of the taxpayer; the taxpayer's Social Security number or federal employer identification number; the amount of taxes owed to such state; and a statement that any administrative or judicial remedies, or both, have been exhausted or have lapsed and that the amount of taxes is legally enforceable under the laws of such state. (3) Upon receipt by the commissioner of the required certification, the commissioner shall notify the taxpayer, if the taxpayer is otherwise entitled to a tax refund from this state, that the commissioner has received a request from the claimant state to withhold all or a portion of any refund, that the taxpayer has the right to protest the withholding of the refund, that failure to file a protest in accordance with subdivision (4) of this subsection shall constitute a waiver of any demand against this state on account of such withheld amount and that the withheld amount will be paid over to the claimant state. Thirty days after the date on which a notice under this subdivision is mailed, such notice shall be final except only for such amounts as to which the taxpayer has filed, as provided in subdivision (4) of this subsection, a written protest with the Commissioner of Revenue Services. (4) Any taxpayer notified in accordance with subdivision (3) of this subsection may, on or before the thirtieth day after the mailing of such notice by the Commissioner of Revenue Services, protest the withholding of all or a portion of a refund by filing with the commissioner a written protest in which the taxpayer shall set forth the grounds on which the protest is based. If a timely protest is filed, the commissioner shall impound the claimed amount of the refund, pay to the taxpayer the unclaimed amount, if any, of the refund, send a copy of the protest to the claimant state for determination of the protest on its merits in accordance with the laws of that state, and pay over to the taxpayer the impounded amount if the claimant state shall fail on or before the forty-fifth day after the sending of the copy of the protest by the commissioner to such claimant state to recertify to the commissioner that the claimant state has reviewed the stated grounds on which the protest is based, and to recertify the amount of taxes which is finally due and payable to the claimant state, which is legally enforceable under the laws of the claimant state against the taxpayer, and with respect to which any administrative or judicial remedies, or both, have been exhausted or have lapsed. (5) Where the amount withheld in accordance with this subsection is a refund of any tax imposed upon the income of individuals and in connection with which the taxpayer filed a joint return with his or her spouse, and the spouse is not a taxpayer, the spouse shall have the right to be paid his or her portion of the refund by establishing his or her share of such refund. The amount of such spouse's share of such refund shall be established by recomputing the spouse's share of the joint liability and subtracting that amount from the taxpayer's contribution toward the joint liability, provided the amount of the overpayment refunded to the spouse shall not exceed the amount of the joint overpayment. (6) Subject to the provisions of subdivisions (3), (4) and (5) of this subsection, the commissioner shall pay over to the claimant state the entire amount withheld or the amount certified, whichever is less; pay any refund in excess of the certified amount to the taxpayer; and, if the amount certified exceeds the amount withheld, withhold amounts from subsequent refunds due to the taxpayer, provided the claimant state agrees to withhold subsequent refunds due to taxpayers certified to the claimant state by the commissioner. (c) The commissioner may enter into agreements with the tax officers of claimant states relating to procedures and methods to be employed by a claimant state with respect to the operation of this section; safeguards against the disclosure or inappropriate use of any information that identifies, directly or indirectly, a particular taxpayer obtained or maintained pursuant to this subsection; and a minimum amount of taxes owed by a taxpayer to a claimant state, so that, if a taxpayer owes less than such amount to such claimant state, the claimant state will not avail itself of the provisions of this section with respect to that taxpayer. (d) The collection procedures prescribed by this section shall not be construed as a substitute for any other remedy available by law to the Commissioner of Revenue Services. (P.A. 98-244, S. 2, 35; P.A. 11-61, S. 54; P.A. 17-105, S. 6.) History: P.A. 98-244 effective June 8, 1998; P.A. 11-61 amended Subsec.

12-36. Jeopardy collection of taxes due state. If, before the due date of any state tax, except a tax imposed under chapter 219 or 229, any state collection agency believes that the collection of such tax will be jeopardized by delay, he shall, subject to the provisions of this section, collect such tax forthwith. He may enforce collection thereof by using the method provided in section 12-35 or by using any other method provided for in the general statutes relating to the enforced collection of taxes. If the amount of such tax has been definitely fixed, the amount so fixed shall be collected. If the amount of such tax has not been definitely fixed, the state collection agency shall collect such amount as, in his opinion, from the facts available to him, is sufficient. If, after the payment of any tax in conformity with the provisions of this section, it is found that the amount so paid is in excess of the amount which would have been paid on the tax due date or after appeal to the courts, the excess so paid shall be returned to the taxpayer upon written application by him to the Comptroller. Such written application shall contain a recital of the facts, shall show the amount of rebate to which the applicant believes he is entitled, shall be approved by the state collection agency and shall be made within the period of one year from the date of the definite determination of such tax. The person against whom jeopardy collection proceedings have been begun may obtain a stay of collection of the whole or any part of the amount of the tax so represented by such proceedings by filing with the state collection agency a bond in such an amount, not exceeding double the amount as to which the stay is desired, and with such surety as the state collection agency deems necessary, conditioned upon the payment of as much of the amount, the collection of which is stayed by the bond, as is found to be due from such person. The amount of the tax which is stayed by the bond shall be paid on notice and demand of the state collection agency at any time after the tax due date. The person subject to jeopardy collection proceedings, under the provisions of this section, who has obtained a stay of collection in whole or in part, may waive such stay at any time in respect to the whole or any part of the amount covered by the bond, 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 the taxpayer, be proportionately reduced. (1949 Rev., S. 1714; P.A. 96-221, S. 20, 25.) History: P.A. 96-221 added exception re chapters 219 and 229, effective June 4, 1996.

Wherever used in this section, “tax” includes not only the principal of any tax but also includes the principal of any license, permit and fee and also all interest, fees, penalties, forfeitures and other charges which may be added by law to the principal of any such tax, license, permit and fee. Each state collection agency may have a suspense tax book. Any state collection agency may, at any time, deliver to the Treasurer and Comptroller a statement showing: (1) The amount of such uncollectible tax shown on the records of the agency; (2) the date when each such tax became due and payable; (3) the name and address of the person against whom each such tax was levied, and (4) the reason why the agency believes each such tax to be uncollectible. At the end of such statement, the agency head shall certify that to the best of his knowledge and belief each tax shown in such statement has not been paid and is uncollectible. Each tax so designated as uncollectible shall thereupon be transferred by such state collection agency to its suspense tax book, and its records shall be written up accordingly. Each tax so transferred shall not thereafter be included as an asset of the state. The amount of each tax so transferred during the last fiscal year and the name and address of the person against whom each such tax was levied shall be available to the public for inspection by any person. Not less than seven years after delivering such a statement to the Treasurer and the Comptroller, the head of the collection agency may request the Abatement Review Committee, as established by section 12-3b, to approve the abatement of any tax designated on such statement as uncollectible. Nothing herein contained shall be construed as an abatement of any tax so transferred, but any such tax, as it has been increased by interest, penalties, fees, fines, forfeitures and other charges, may be collected by the state collection agency then or subsequently in office. (1949 Rev., S. 1715; P.A. 77-614, S. 19, 610; P.A. 86-215, S. 1, 2; P.A. 96-221, S. 14, 25.)

Upon such approval, said commissioner shall certify such abatement to the Treasurer and Comptroller. (b) The commissioner shall prepare and maintain a list related to each type of tax levied by the state containing the name and address of any person whose tax, and any penalty or interest payable in connection therewith, has been abated, in whole or in part, and the amount thereof.

Such remittance shall not be deemed to be a concession by the taxpayer of the liability therefor and shall not diminish or abrogate the taxpayer's right to contest the applicability of the tax, interest or penalty, prior to the time otherwise available for contesting the tax or penalty. (b) Notwithstanding the provisions of section 12-39h, at the time of the application of the cash bond upon the final resolution of the controversy, there shall be applied first to the payment of the tax finally determined to be due so much of the cash bond as is represented by the ratio, determined as of the date of receipt of the cash bond, of the tax assessed over the total of the tax assessed and the interest accrued as of such date, and the balance shall be treated as interest paid on the tax assessed as of such date. Interest on the outstanding balance of the tax due and not deemed satisfied by the cash bond shall be determined as if the cash bond so applied to the payment of tax had been a tax payment as of the date of receipt of the cash bond, such that the deposit stops the further accrual or compounding of interest with respect to the portion of the assessment deemed paid as of such date. The balance of the cash bond, if any, shall be applied to the payment of interest as of the date of receipt of the cash bond, with any excess applied in accordance with said section 12-39h. (c) A taxpayer having remitted a cash bond in accordance with this section shall not be entitled to the payment of interest with respect to that portion of the tax assessment that is subsequently abated by action of the Commissioner of Revenue Services or a court of competent jurisdiction to the extent the amount of such assessment was represented by such cash bond.

(d) The taxpayer may request a return of all or part of the cash bond at any time before the expiration of the later of the time period for contesting such tax or the entry of an order by the Superior Court upholding such assessment, unless the Commissioner of Revenue Services determines that collection of the tax would be in jeopardy, in which case the cash bond will not be returned, but will be applied against such assessment. Upon the return of such amounts, the taxpayer shall be treated for all purposes hereunder as if such cash bond had never been paid. (e) The Commissioner of Revenue Services may adopt regulations, in accordance with the provisions of chapter 54, to implement the provisions of subsections (a) to (d), inclusive, of this section. (May Sp. Sess. P.A. 94-4, S. 42, 43, 85; P.A. 95-160, S. 64, 69; P.A. 98-244, S. 3, 35; P.A. 99-121, S. 2, 28.) History: May Sp. Sess.
