How Arizona taxes your paycheck
Arizona has a unique approach: instead of the employer calculating your withholding, you choose your own withholding percentage on Form A-4. There are 12 options ranging from 0.5% to 5.1%.
How it works:
- You select a withholding percentage on Form A-4
- Your employer withholds that percentage from each paycheck
- When you file your AZ return, the actual tax is a flat 2.5%
- You either get a refund (if you over-withheld) or owe (if you under-withheld)
In addition to the elected AZ withholding, your paycheck includes:
- Federal income tax (10%–37%)
- Social Security (6.2% up to $176,100)
- Medicare (1.45% + 0.9% over $200k)
Arizona has no local income taxes and no mandatory state payroll programs like NJ or WA.

Frequently asked questions
How does Arizona state tax withholding work?
Arizona is unique — you choose your own withholding percentage on Form A-4. Options range from 0.5% to 5.1% of gross taxable wages. The standard rate is 2.0%. When you file your annual return, the actual tax is a flat 2.5%, and you either get a refund or owe the difference.
What withholding rate should I choose?
The flat income tax rate is 2.5%. If you choose 2.0% withholding, you'll likely owe a small amount when you file. If you choose 2.7% or 3.0%, you'll likely get a refund. The standard 2.0% is the most common choice. You can change your rate at any time by filing a new Form A-4.
What is Arizona's actual income tax rate?
Arizona has a flat 2.5% income tax rate (as of 2023). This is the rate applied when you file your annual return. The withholding rate you select for your paycheck is just an estimated prepayment. Arizona previously had progressive brackets but moved to a flat rate.
Does filing status affect Arizona state tax?
No. Since Arizona uses a flat rate and employee-elected withholding, your filing status does not change your paycheck withholding rate. Filing status does affect your federal withholding.
Is 401(k) pre-tax for Arizona state income tax?
Yes. 401(k) contributions reduce your gross taxable wages for both federal and Arizona state withholding purposes.
Does Arizona have local income taxes?
No. Arizona does not have county or municipal income taxes. However, some Arizona cities levy a Transaction Privilege Tax (similar to sales tax) on businesses, which is not deducted from your paycheck.
How accurate is this calculator?
This calculator applies your elected withholding percentage to gross wages. Since AZ withholding is a simple percentage, the estimate is very accurate. Federal tax uses 2025 rates. Your actual annual tax liability is a flat 2.5% when you file.
How does Arizona compare to other states?
Arizona's flat 2.5% is one of the lowest income tax rates in the country. Only a few states with income taxes have lower rates (North Dakota at 1.95%). States like California (13.3% top rate) and Oregon (9.9% top rate) take significantly more from your paycheck.
