Arizona Paycheck Calculator

Paycheck taxes 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 ($15,750 single / $31,500 married filing jointly), and instead of personal exemptions the state offers dependent tax credits.

Bonuses and supplemental wages in Arizona

Bonuses and other supplemental wages are frequently withheld differently from regular pay, and states set their own rules. This calculator applies Arizona's regular withholding to every dollar and does not model a separate supplemental rate, so a bonus paycheck can come out higher or lower than the figure above. Federal supplemental withholding is a flat 22% up to $1 million; for Arizona's own treatment, check the state authority linked below.

For the federal half, which this site does model, compare what withholding takes from a bonus against what you actually owe — the 22% flat rate is withholding, not a tax bill, and the difference comes back at filing.

Arizona vs. its neighbors

On a $100,000 salary you keep $77,074 in Arizona — $3,102 more than in neighboring California, $2,344 more than in Utah, and $1,586 more than in Colorado.

Federal income tax and FICA are identical in every state, so the whole gap above is state income tax. Single filer, $100,000 of wages, no 401(k) or other pre-tax deductions, 2025 state tables. Local income taxes (city and county) are not included. Run your own salary through the calculator above, or on any state's page.

Neighbours are only part of the picture. The study behind these figures ranks what a $100,000 salary takes home in all 50 states, with Arizona's row in place — the entire spread between best and worst is state income tax, since federal tax and FICA are identical everywhere.

A worked example at Arizona's median income

Arizona's median household income is $84,700 (2024, U.S. Census Bureau via FRED (real median household income)). Run through the same engine as the calculator above (single filer, taxes only):

That is an effective all-in tax rate of 21.3% at the median — your own number depends on filing status, 401(k), and benefits. Enter your salary above for the exact figure.
