Arizona Paycheck Calculator

Four tax lines come out of an Arizona paycheck: federal income tax, Social Security (6.2% up to $184,500), Medicare (1.45%), and Arizona withholding at the rate on your A-4. Arizona cities and counties do not tax wages, and the state has no disability, paid-leave, or long-term care premium for employees. Anything else on your stub is your own election: 401(k), health premiums, HSA, and similar benefits.

Arizona withholding has no brackets, allowances, or exemptions. You pick one of seven percentages on Form A-4 (0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, or 3.5%), your employer multiplies your gross taxable wages by it, and you can add a fixed extra dollar amount per paycheck. With no A-4 on file the employer uses 2.0%. Set your election in the Arizona withholding rate selector on this page; it starts at the 2.0% default and every line recomputes when you change it.

The election is a prepayment against a flat 2.5% tax on Arizona taxable income. HB 4168, signed in June 2026, raised the standard deduction to $15,750 single, $23,625 head of household, and $31,500 married filing jointly, indexed to the federal amount and applied retroactively to 2026. Because the deduction removes part of your wages from tax, 2.5% of gross over-withholds for most single earners and 2.0% lands close: on a $60,000 salary the 2.0% election withholds $1,200 for the year against roughly $1,100 of tax.

Employees who expect to owe no Arizona tax can elect 0% on the A-4, renewed by February 15 each year. Residents of California, Indiana, Oregon, or Virginia who work in Arizona can file Form WEC to stop Arizona withholding and take a credit at home, and nonresidents in Arizona under 60 days a year are outside mandatory withholding. This site's bonus calculator applies Arizona's 2.0% default rate; if your A-4 election differs, use the selector on this page for a closer figure.
