Reporting federal adjustments - definitions

(f) Federal adjustment means a change to an item or amount determined under the internal revenue code that is used by a taxpayer to compute the tax due under this article 22 whether that change results from action by the internal revenue service, including a partnership level audit, or the filing of an amended federal return, federal refund claim, or administrative adjustment request by the taxpayer. A federal adjustment is positive to the extent that it increases federal taxable income as determined under this article 22 and is negative to the extent that it decreases federal taxable income as determined under this article 22.

(i) Final determination date means:

(I) Except as otherwise provided in this subsection (1)(i), if the federal adjustment arises from an internal revenue service audit or other action by the internal revenue service, the first day on which no federal adjustments arising from the audit or other action remain to be finally determined, whether by internal revenue service decision with respect to which all rights of appeal have been waived or exhausted, by agreement, or, if appealed or contested, by a final decision with respect to which all rights of appeal have been waived or exhausted. For agreements required to be signed by the internal revenue service and the taxpayer, the final determination date is the date on which the last party signed the agreement.

(II) For federal adjustments arising from an internal revenue service audit or other action by the internal revenue service, if the taxpayer filed a combined report, a consolidated return, or a combined and consolidated return, the first day on which no related federal adjustments arising from that audit remain to be finally determined, as described in subsection (1)(i)(I) of this section, for the entire group;

(III) If the federal adjustment results from filing an amended federal return, a federal refund claim, or an administrative adjustment request, or if it is a federal adjustment reported on an amended federal return or other similar report filed pursuant to section 6225 (c) of the internal revenue code, the day on which the amended return, refund claim, administrative adjustment request, or other similar report was filed.

(s) Tiered partner means any partner that is a partnership or pass-through entity.

(2) Except in the case of final federal adjustments that are required to be reported by a partnership and its partners using the procedures in subsection (3) of this section, and final federal adjustments required to be reported for federal purposes by taking those adjustments into account in the partnership return for the year of adjustment, a taxpayer shall report and pay any tax due under this article 22 with respect to final federal adjustments arising from an audit or other action by the internal revenue service or reported by the taxpayer on a timely filed amended federal income tax return, including a return or other similar report filed pursuant to section 6225 (c)(2) of the internal revenue code, or federal claim for refund by filing a federal adjustments report with the executive director for the reviewed year and, if applicable, paying the additional tax owed under this article 22 by the taxpayer no later than one hundred eighty days after the final determination date.

(3) (a) Except for adjustments required to be reported for federal purposes by taking those adjustments into account in the partnership return for the year of adjustment and the distributive share of adjustments that have been reported as required under subsection (2) of this section, partnerships and partners shall report final federal adjustments arising from a partnership level audit or an administrative adjustment request and make payments as required under this subsection (3).

(b) (I) With respect to an action required or permitted to be taken by a partnership under this subsection (3) and a proceeding under section 39-21-103 or 39-21-105 with respect to that action, the state partnership representative for the reviewed year has the sole authority to act on behalf of the partnership, and the partnership's direct partners and indirect partners are bound by those actions.

(II) The state partnership representative for the reviewed year is the partnership's federal partnership representative unless the partnership designates in writing another person as its state partnership representative.

(III) The executive director may establish reasonable qualifications and procedures for designating a person other than the federal partnership representative to be the state partnership representative.

(c) (I) Final federal adjustments subject to the requirements of this subsection (3), except for those subject to a properly made election under subsection (3)(d) of this section, must be reported as provided in this subsection

(3)(c).

(II) No later than ninety days after the final determination date, the partnership shall:

(A) File a completed federal adjustments report with the executive director including any information the executive director may prescribe;

(B) Notify each of its direct partners of their distributive share of the final federal adjustments including any information the executive director may prescribe;

(C) File an amended composite return for direct partners as required under section 39-22-601 (5)(d) or (5.5)(d), as applicable, or an amended return under subpart 3 of part 3 of this article 22, and pay the additional amount that would have been due had the final federal adjustments been reported properly as required; and

(D) For any direct partner for which payment was made under section 39-22-601 (5)(h), pay the additional amount that would have been due had the final federal adjustments been reported properly as required.

(III) Except as provided under subsection (4) of this section, no later than one hundred eighty days after the final determination date, each direct partner that is not included in an amended composite return under subsection (3)(c)(II)(C) of this section and that is subject to tax under section 39-22-104 shall:

(A) File a federal adjustments report reporting their distributive share of the adjustments reported to them under subsection (3)(c)(II)(B) of this section; and

(d) (I) No later than ninety days after the final determination date, an audited partnership making an election under this subsection (3)(d) shall file a completed federal adjustments report, including such information as the executive director may prescribe, and notify the executive director that it is making the election under this subsection (3)(d).

(III) Final federal adjustments subject to the election provided in this subsection (3)(d) exclude:

(A) The distributive share of final audit adjustments that under part 3 of this article 22 must be included in the unitary business income of any direct or indirect corporate partner if the audited partnership can reasonably determine this; and

(B) Any final federal adjustments resulting from an administrative adjustment request.

(IV) An audited partnership not otherwise subject to any reporting or payment obligation to the state that makes an election under this subsection (3)(d) consents to be subject to Colorado laws related to reporting, assessment, payment, and collection of Colorado tax calculated under the election.

(e) Subject to the limitations in subsection (3)(d)(III) of this section, the amount due under subsection (3)(d)(II) of this section is calculated as follows:

(I) Exclude from final federal adjustments the distributive share of these adjustments reported to a direct exempt partner not subject to tax under section 39-22-112 (1);

(II) For the total distributive shares of the remaining final federal adjustments reported to direct corporate partners subject to tax under section 39-22-301, and to direct exempt partners subject to tax under section 39-22-112 (2), apportion and allocate such adjustments as provided under section 39-22-303.6 and multiply the resulting amount by the highest tax rate in effect under section 39-22-301;

(III) For the total distributive shares of the remaining final federal adjustments reported to nonresident partners that are direct partners subject to tax under section 39-22-104, determine the amount of such adjustments derived from sources within Colorado under section 39-22-203 and multiply the resulting amount by the highest tax rate in effect under section 39-22-104;

(IV) For the total distributive shares of the remaining final federal adjustments reported to tiered partners:

(A) Determine the amount of such adjustments which is of a type that it would be subject to sourcing by a nonresident partner under section 39-22-109 and then determine the portion of this amount that would be sourced to the state applying the rules of that section;

(B) Determine the amount of such adjustments which is of a type that it would not be subject to sourcing by a nonresident partner under section 39-22-109;

(C) Determine the portion of the amount determined in subsection

(3)(e)(IV)(B) of this section that can be established, under rules promulgated by the executive director, to be properly allocable to nonresident partners that are indirect partners or other partners not subject to tax on the adjustments or that can be excluded under procedures for a modified reporting and payment method allowed under subsection (3)(g) of this section;

(V) Multiply the total of the amounts determined in subsection (3)(e)(IV)(A) and (3)(e)(IV)(B) of this section and then reduced by the amount determined in subsection (3)(e)(IV)(C) of this section by the highest tax rate in effect under section 39-22-104;

(VI) For the total distributive shares of the remaining final federal adjustments reported to resident partners that are direct partners subject to tax under section 39-22-104, multiply that amount by the highest tax rate in effect under section 39-22-104; and

(VII) Add the amounts determined in subsections (3)(e)(II), (3)(e)(III), (3)(e)(V), and (3)(e)(VI) of this section along with penalty and interest as provided in section 39-22-621.

(f) The direct and indirect partners of an audited partnership that are tiered partners and all of the partners of those tiered partners that are subject to tax under this article 22 are subject to the reporting and payment requirements of subsection (3)(b) of this section, and the tiered partners are entitled to make the elections provided in subsection (3)(d) and (3)(g) of this section. The tiered partners or their partners shall make required reports and payments no later than ninety days after the time for filing and furnishing statements to tiered partners and their partners as established under section 6226 of the internal revenue code and the regulations thereunder. The executive director may promulgate rules to establish procedures and interim time periods for the reports and payments required by tiered partners and their partners and for making the elections under this subsection (3).

(g) Under procedures adopted by and subject to the approval of the executive director, an audited partnership or tiered partner may enter into an agreement with the executive director to utilize an alternative reporting and payment method, including applicable time requirements or any other provision of this subsection (3), if the audited partnership or tiered partner demonstrates that the requested method will reasonably provide for the reporting and payment of taxes, penalties, and interest due under the provisions of this subsection (3) or if the audited partnership or tiered partner can show that their direct partners have agreed to allow a refund of the state tax to the entity. Application for approval of an alternative reporting and payment method must be made by the audited partnership or tiered partner within the time for election as provided in subsection

(3)(d) or (3)(f) of this section, as appropriate.

(h) (I) The election made pursuant to subsection (3)(d) or (3)(g) of this section is irrevocable, unless the executive director, in the executive director's discretion, determines otherwise.

(II) If properly reported and paid by the audited partnership or tiered partner, the amount determined in subsection (3)(e) of this section, or similarly under an optional election under subsection (3)(g) of this section, will be treated as paid in lieu of taxes owed by its direct and indirect partners, to the extent applicable, on the same final federal adjustments. The direct partners or indirect partners may not take any deduction or credit for this amount or claim a refund of the amount in the state. Nothing in this subsection (3)(h)(II) precludes a resident partner that is a direct partner from claiming a credit against taxes paid to the state pursuant to section 39-22-108 for any amounts paid by the audited partnership or tiered partner on the resident partner's behalf to another state or local tax jurisdiction.

(i) Nothing in this subsection (3) prevents the executive director from assessing direct partners or indirect partners for taxes they owe, using the best information available, if a partnership or tiered partner fails to timely make any report or payment required by this subsection (3) for any reason.

(4) The executive director may promulgate rules to establish a de minimis amount upon which a taxpayer shall not be required to comply with subsections (2) and (3) of this section.

(5) The executive director shall assess additional tax, interest, and penalties arising from final federal adjustments arising from an audit by the internal revenue service, including a partnership level audit, or reported by the taxpayer on an amended federal income tax return or as part of an administrative adjustment request on or before the following dates:

(a) If a taxpayer files with the executive director a federal adjustments report or an amended return as required within the period specified in subsection

(2) or (3) of this section, the executive director may assess any amounts, including in-lieu-of amounts, taxes, interest, and penalties arising from those federal adjustments, if the executive director issues a notice of deficiency to the taxpayer on or before the later of:

(I) The expiration of the limitations period specified in section 39-21-107 (2); or

(II) The expiration of the one-year period following the date of filing with the executive director of the federal adjustments report.

(b) If the taxpayer fails to file the federal adjustments report within the period specified in subsection (2) or (3) of this section, as appropriate, or the federal adjustments report filed by the taxpayer omits final federal adjustments or understates the correct amount of tax owed, the executive director may assess any taxes, interest, and penalties arising from the final federal adjustments if the executive director issues a notice of deficiency to the taxpayer on or before the later of:

(I) The expiration of the limitations period specified in section 39-21-107 (2);

(II) The expiration of the one-year period following the date the federal adjustments report was filed with the executive director; or

(III) In the absence of fraud, the expiration of the six-year period following the final determination date.

(6) A taxpayer may make estimated payments to the executive director, following the process prescribed by the executive director, of the Colorado tax expected to result from a pending internal revenue service audit prior to the due date of the federal adjustments report without having to file the report with the executive director. The estimated tax payments shall be credited against any tax liability ultimately found to be due to Colorado and will limit the accrual of further statutory interest on that amount. If the estimated tax payments exceed the final tax liability and statutory interest ultimately determined to be due, the taxpayer is entitled to a refund or credit for the excess if the taxpayer files a federal adjustments report or claim for refund or credit of tax no later than one year following the final determination date.

(7) (a) Except for final federal adjustments required to be reported for federal purposes by taking those adjustments into account in the partnership return for the year of adjustment, a taxpayer may file a claim for refund or credit of tax arising from federal adjustments made by the internal revenue service on or before the later of:

(I) The expiration of the last day for filing a claim for refund or credit of tax pursuant to section 39-21-108 (1), including any extensions; or

(II) One year from the date a federal adjustments report prescribed in subsection (2) or (3) of this section, as applicable, was due to the executive director, including any extensions pursuant to subsection (8) of this section.

(b) The federal adjustments report is the means for the taxpayer to report additional tax due, report a claim for refund or credit of tax, and make other adjustments including to its net operating losses resulting from adjustments to the taxpayer's federal taxable income. Any refund granted to the entity under subsection (3) of this section is in lieu of state tax that may be owed to the partners.

(8) (a) Unless otherwise agreed to in writing by the taxpayer and the executive director, any adjustments by the executive director or by the taxpayer made after the expiration of the period described in section 39-21-107 (2) or 39-21-108 (1), as applicable, is limited to changes to the taxpayer's tax liability arising from federal adjustments.

(b) The periods provided for in this section may be extended:

(I) Automatically, upon written notice to the executive director, by sixty days for an audited partnership or tiered partner which has ten thousand or more direct partners; or

(II) By written agreement between the taxpayer and the executive director.

(c) Any extension granted under this subsection (8) for filing the federal adjustments report extends the last day prescribed by law for assessing any additional tax arising from the adjustments to federal taxable income and the period for filing a claim for refund or credit of taxes.

(9) This section applies to any adjustments to a taxpayer's federal taxable income with a final determination date occurring on and after January 1, 2024.
