AZ HB2383

Updates Arizona's Internal Revenue Code conformity date from January 1, 2022 to January 1, 2023 for taxable years beginning after December 31, 2022.

Amends Section 42-1001 to define "internal revenue code" as the U.S. Internal Revenue Code of 1986 as amended and in effect on January 1, 2023, including retroactive provisions effective during 2022.

Amends Section 43-105 to add a new provision (subsection A) establishing IRC conformity for taxable years 2023 and beyond using the January 1, 2023 effective date.

For taxable years 2021-2022, specifically includes retroactive provisions of the CHIPS and Science Act (P.L. 117-167), Inflation Reduction Act (P.L. 117-169), and Consolidated Appropriations Act, 2023 (P.L. 117-328).

Renumbers subsequent subsections in Section 43-105 to accommodate the new provision while maintaining existing language for prior tax years.
