Income tax in Arizona

Arizona taxes all income at a flat 2.5% for tax year 2025 — the lowest flat income tax rate in the country, in place since 2023. Its standard deduction mirrors the federal amounts, and instead of personal exemptions the state offers dependent tax credits. Long-term capital gains get a break: Arizona allows a 25% subtraction of net long-term gains on assets acquired after 2011, so the effective rate on those gains is about 1.9%.
