Arizona Paycheck Calculator
Your Arizona Paycheck Breakdown
Arizona has one of the lowest state income tax rates in the country, and that alone can make a paycheck confusing to predict. You know your rate is low, but between federal tax, Social Security, and Medicare, the final number on your pay stub still comes as a surprise to a lot of people.
This calculator clears that up. Type in your gross pay, pick your pay schedule, and get the exact split between what goes to taxes and what actually lands in your account.
Breaking Down Every Deduction on Your Check
Enter your gross pay for one pay period, choose weekly, biweekly, semi-monthly, or monthly, then pick single or married filing status. Add any pre-tax deductions like a 401k contribution or health premium, and the calculator handles the rest.
It runs your annualized income through the current federal brackets, applies Arizona's flat state rate, and subtracts Social Security and Medicare. What's left is your real net pay, the number that actually hits your bank account.
Why Arizona's Flat Rate Is Deceptively Simple
A 2.5 percent state tax sounds tiny, and compared to states like California it is. But federal tax is still the biggest bite out of most paychecks by far, so a low state rate doesn't mean a huge paycheck. It just means Arizona takes a smaller slice than most other income-tax states.
The Math, Step by Step
Arizona's income tax formula couldn't be simpler: taxable wages multiplied by 2.5 percent. Federal tax works differently, using brackets that tax different chunks of your annual income at different rates. FICA stays flat at 6.2 percent for Social Security up to the annual cap, and 1.45 percent for Medicare with no cap.
Take a biweekly paycheck of $1,800, single filer, no pre-tax deductions. Annualized, that's $46,800. After the $15,750 standard deduction, taxable income is $31,050, sitting in the 10 and 12 percent brackets, giving roughly $2,880 in annual federal tax, or $110.77 per paycheck. Arizona tax on $1,800 is $45. Social Security is $111.60 and Medicare is $26.10. Net pay lands around $1,506.53 for that check.
A Real Paycheck Scenario
Say you just took a new job in Phoenix paying $22 an hour, 40 hours a week. Before your first paycheck arrives, you want to know if that hourly rate actually covers your rent and car payment. Multiply $22 by 80 hours for a biweekly gross of $1,760, run it through this calculator, and you'll know your real net pay before your first pay stub even lands, which makes budgeting for that first month a lot less stressful.
Common Paycheck Mistakes
- Assuming Arizona's low tax rate means a big paycheck. Federal tax is almost always the larger deduction by a wide margin.
- Forgetting that Social Security stops being withheld once you hit the annual wage cap, usually late in the year for higher earners.
- Mixing up gross pay with taxable pay when pre-tax deductions are involved. Only taxable pay gets hit with income tax.
- Not adjusting withholding after a raise, which can lead to a surprise tax bill the following spring.

FAQs
What is Arizona's state income tax rate?
Arizona applies a flat 2.5 percent tax to taxable income. It's one of the lowest state income tax rates among states that charge income tax at all.
Does Arizona have local city income tax?
No. Arizona cities cannot levy a local income tax, so the 2.5 percent state rate is the only income tax withheld from your paycheck.
Why does my paycheck change even though my salary stayed the same?
Pay periods with extra days, changes in benefits enrollment, or hitting the Social Security wage cap can all shift your net pay slightly even without a raise.
Is overtime taxed at a higher rate in Arizona?
No. Overtime pay is taxed the same way as regular wages. It just adds to your total taxable income for that pay period.
Does this calculator include local Arizona sales tax?
No. Sales tax isn't part of a paycheck calculation. This tool only covers income tax withholding and FICA deductions from wages.
Can self-employed workers use this calculator?
Not directly. Self-employed income is subject to self-employment tax instead of standard FICA withholding, so the math is different from a W-2 paycheck.
What counts toward pre-tax deductions?
Traditional 401k contributions, traditional health insurance premiums, and HSA contributions typically qualify and reduce your taxable wages.
How often should I check my paycheck withholding?
Anytime you get a raise, change filing status, or add a dependent. Checking once a year at minimum helps avoid surprises at tax time.
