  • SB1638 — Senate Bill 1638 is discussed as a tax conformity bill that updates Arizona statutes to match the Internal Revenue Code as of January 1, 2026, while also incorporating H.R. 1-related changes such as income tax subtractions for tips, overtime, seniors, and auto loan interest. The discussion then turns to two amendments, including a 16-page amendment that clarifies retroactive application of the updated Internal Revenue Code definition and the treatment of foreign dividend income for tax subtraction purposes. Later remarks note that the bill makes the conformity language law while removing certain corporate-related provisions, and questions are raised about how the business-side provisions affect large corporations versus small businesses.

The discussion also references that the bill previously did not include SALT conformity, tying the amendment debate to the bill’s tax conformity provisions.
  • SB1368 — First clear mention of the bill; Palomino opposes it and argues it does not fit Arizona's budget realities.
