individual income tax; rate; increase

HB 2636 proposes to increase Arizona's individual income tax rates for taxable years beginning after December 31, 2021. The bill would amend tax brackets to raise rates across all income levels for both residents and nonresidents earning income within Arizona. Key provisions include adjusting the percentage rates applied to different income ranges, such as increasing the top marginal rate for single filers and married couples filing jointly. This legislation directly affects all Arizona taxpayers subject to individual income tax, with changes applying to future tax years. The bill is currently in early legislative stages (House First/Second Reading in 2026).
