ANNOTATION

Subsection (5.3) unambiguously incorporates the federal Internal Revenue Code of 1986, "as amended, . . . for the taxable year", without limitation as to when an amendment is enacted or goes into effect. Absent an amendment by the general assembly to the state income tax code to not conform with changes to the federal Internal Revenue Code, state law automatically incorporates amendments to the federal Internal Revenue Code, including amendments that relate to previous tax years. Therefore, a taxpayer can take advantage of any amendment that is in effect for, not just in, a taxable year. Anschutz v. Dept. of Rev., 2022 COA 132, 524 P.3d 1203.

Department's emergency rule interpreting "internal revenue code" for purposes of subsection (5.3) was contrary to statute's plain language and not entitled to deference. Emergency rule erroneously defined "internal revenue code" to exclude any federal statutory changes enacted after the last day of the taxable year, contrary to statute, which automatically incorporates amendments to the federal Internal Revenue Code, without limitation to laws that are prospective in their operation. Anschutz v. Dept. of Rev., 2022 COA 132, 524 P.3d 1203.

Trial court erred in granting department's motion to dismiss taxpayers' refund claim made in amended return based on retroactive amendment to federal tax statutes. Taxpayers were entitled to file an amended state income tax return for the 2018 tax year claiming entirety of their "excess business loss" as deduction based on the federal Coronavirus Aid, Relief, and Economic Security Act of 2020, which suspended the "excess business loss" deduction limits for the 2018 through 2020 tax years. Anschutz v. Dept. of Rev., 2022 COA 132, 524 P.3d 1203.
