SB 1633 amends Arizona's tax code to update the deduction for adoption-related expenses under Section 43-1022. It sets new annual limits: $3,000 for single filers or married couples filing separately before 2026, increasing to $5,000 for single filers/head of household and $10,000 for married couples filing jointly starting in 2026. This deduction directly affects Arizona taxpayers who incurred adoption costs (including medical, legal, and agency fees) in prior years, allowing them to subtract these expenses when filing taxes. The bill does not address primary residence deductions, as the title suggests; instead, it modifies existing adoption expense rules with updated dollar limits. The bill is currently in early legislative stages (Senate First and Second Readings in 2026).
