(b) (1) (A) The provisions of this subsection shall not apply to taxable years commencing on or after January 1, 2018, and prior to January 1, 2024.
(B) With respect to each of its nonresident partners, each partnership doing business in this state or having income derived from or connected with sources within this state shall, for each taxable year, make payment to the commissioner as provided in subdivision (2) of this subsection.
(C) For taxable years commencing on or after January 1, 2024, the payment due with respect to each nonresident partner under this subsection shall be reduced by such partner's direct and indirect credit properly reported by the partnership under subdivision (1) of subsection (f) of section 12-699. In no event shall the payment with respect to any nonresident partner 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 partner's distributive share of (i) such partnership's separately and nonseparately computed items, as described in Section 702(a) 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 partnership's income, gain, loss or deduction, to the extent derived from or connected with sources within this state, as determined under this chapter. Any amount paid by a partnership to this state with respect to any taxable year pursuant to this subdivision shall be considered to be a payment by the partner on account of the income tax imposed on the partner for such taxable year pursuant to this chapter. A partnership shall not be liable to, and shall be entitled to recover a payment made pursuant to this subdivision from, the partner on whose behalf the payment was made. Any payment for a taxable year shall be made on or before the date the annual return for such taxable year is required to be filed pursuant to section 12-726.

(B) (i) If income from one or more pass-through entities, as defined in subparagraph (D) of this subdivision, is the only source of income derived from or connected with Connecticut sources of a partner, or the partner and his or her spouse if a joint federal income tax return is or shall be made, the filing by the partnership of an annual return pursuant to section 12-726 and the payment by the partnership on behalf of the partner of the tax prescribed under subparagraph (A) of this subdivision shall satisfy the filing and payment requirements otherwise separately imposed on the partner by this chapter. 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 refund or credit any overpayment to either the partnership or the partner, in the commissioner's sole discretion. Except as otherwise provided in section 12-732, any such overpayment shall be refunded or credited not later than three years from the due date of the partnership's annual return pursuant to section 12-726 or, if the time for filing such return was extended, not later than three years from the date on which such return is filed or the extended due date of such return, whichever is earlier.

In such event, the partner shall receive credit for the income tax paid under this subdivision by the partnership on his or her behalf. 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. If the commissioner chooses to make any deficiency assessment against the partnership, then, 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 refund or credit any overpayment that is related to the partner's share of partnership items to 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.
