AZ HB4029

Requires the Governor's Office of Strategic Planning and Budgeting and the Joint Legislative Budget Committee to annually evaluate whether conforming Arizona tax law to federal Internal Revenue Code changes would result in income tax revenue increases or decreases of $100,000,000 or more.

Mandates the Governor to determine by September 30 each year whether a special legislative session is necessary to address significant IRS code changes and notify legislative leadership in writing of that determination.

Moves the Department of Revenue's deadline for submitting an initial report on IRS code revisions to September 30 (from January 10), with a final report still due by January 10.

Prohibits the Department of Revenue from prescribing tax return forms that are inconsistent with statutes in effect on the date the forms are issued.

Updates language throughout the tax code to use gender-neutral terms (replacing "he" with "the director") and modernizes statutory phrasing.
