Arizona Paycheck Calculator 2026

Arizona Payroll Tax Overview

Arizona uses a flat state income tax rate of 2.5% on all taxable wages. Unlike graduated-bracket states, every dollar you earn in Arizona above the standard deduction is taxed at the same 2.5% rate. This makes Arizona paycheck calculations straightforward and predictable.

On top of state income tax, workers in Arizona also pay federal income tax (10%–37% graduated brackets), Social Security (6.2% up to the $176,100 wage base), and Medicare (1.45%, or 2.35% above $200,000 for high earners). Pre-tax deductions like 401(k) and health insurance reduce both federal and state taxable income.

The 2026 federal income tax brackets for single filers: 10% on the first $11,925; 12% to $48,475; 22% to $103,350; 24% to $197,300; 32% to $250,525; 35% to $626,350; 37% above. Your effective federal rate will be well below the marginal rate at most income levels.

Federal vs Arizona Tax Burden

For a Arizona single filer earning $60,000 annually, estimated federal income tax is roughly $6,748 (11.2% effective), plus Arizona state tax of $1,050 (flat 2.5%), Social Security $3,720, and Medicare $870. Estimated annual take-home: approximately $47,600.

The flat tax structure means Arizona does not penalize additional income with a higher marginal state rate — every extra dollar earned is taxed at exactly 2.5% for state purposes. This can make Arizona attractive for higher earners who benefit from the predictability of a flat system.

Pre-tax 401(k) contributions, HSA contributions, and health insurance premiums reduce both federal and Arizona taxable income before tax is applied. Maximizing pre-tax deductions is one of the most effective ways to reduce your Arizona paycheck tax burden.

How to Use This Arizona Paycheck Calculator

Enter your pay period (weekly, biweekly, semimonthly, monthly, or annual), then input either your annual gross salary or your hourly rate and average hours per week. Select your federal filing status — single, married filing jointly, married filing separately, or head of household — as this determines your federal tax brackets and standard deduction.

If you have pre-tax deductions such as a 401(k) contribution, health insurance premium, or HSA contribution, enter the total per-period dollar amount. These reduce your taxable income before federal and state taxes are calculated. The calculator will show federal income tax, Social Security (6.2%), Medicare (1.45%), Arizona state income tax (2.5%), your total deductions, and your net take-home pay — both per period and annualized.

Results are estimates based on standard assumptions and 2026 tax rates. Actual withholding may differ based on your W-4 elections, additional withholding, local taxes (in some cities), or retirement plan contribution limits. For precise payroll calculations, consult your payroll provider or a tax professional.

Paycheck Calculator Arizona: 2026 Form A-4 Withholding and TPT Reminder

Arizona employees must file Form A-4 with every employer to set state withholding as a percentage of federal taxable wages. Per the Arizona Department of Revenue withholding forms page, the 2026 default rate is 2.0% if no A-4 is on file, but employees can elect 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, or 3.5% to closer-match the flat 2.5% state liability. A common paycheck calculator arizona mistake: employees select 0.5% then owe hundreds at April 15 because the withholding under-covered the flat rate. Run this calculator with your gross annual, then adjust your A-4 rate so annual withholding ≥ annual state tax. Self-employed AZ residents pay estimated tax via Form 140ES quarterly (April 15, June 15, September 15, January 15). Last updated: 2026-07-15.
