Arizona House floor debated and voted to pass a tax-conformity measure (House Bill 2153 as substituted by Senate Bill 1106) that would align state law with recent federal tax changes, make the changes retroactive to Jan. 1, 2025, and enact a package of child- and senior-focused tax relief. The bill passed on a 31-27 vote after about 30 minutes of floor debate and multiple explanations of vote.
