## Assumptions

- An estimate for a full-year resident, 2025 rates, not tax advice.
- Starts from federal AGI; Arizona additions and subtractions are not modelled.
- Not modelled for Arizona: 2026 standard deduction pending state legislation; uses the 2025 amounts. Dependent credit ($100 per child under 17) not modelled.
- Not modelled: part-year and nonresident returns, other state credits, and state AMT.

## Worked examples

1. status = single, income = $50,000.00, deps = 0 gives taxableIncome = $34,250.00, stateTax = $856.25, total = $856.25. Source: Arizona Department of Revenue, Individual Income Update February 2026 (2025 standard deduction), https://azdor.gov/sites/default/files/document/IND_Updates-2602.pdf (worked from it at AGI $50,000, single).
2. status = mfj, income = $100,000.00, deps = 2 gives taxableIncome = $68,500.00, stateTax = $1,712.50, total = $1,712.50.
3. status = hoh, income = $200,000.00, deps = 1 gives taxableIncome = $176,375.00, stateTax = $4,409.38, total = $4,409.38.

## FAQ

### What is the Arizona income tax rate?

Arizona taxes income at a flat 2.5%. For a single filer the schedule is 2.5% above $0 of taxable income. These are the 2025 (the latest Arizona has published) rates.

### How is Arizona income tax calculated?

Start from federal adjusted gross income. Subtract the larger of the Arizona standard deduction and your itemized deductions, then the exemptions. Apply the rates to what is left and subtract any credits. The standard deduction is $15,750 single, $31,500 married filing jointly, $15,750 separately, and $23,625 head of household. The model has no exemptions or credits for this state.

### Does Arizona have a local income tax?

This page has no local income tax for Arizona; if your city or county has one, add it yourself.

### What does this Arizona calculator leave out?

2026 standard deduction pending state legislation; uses the 2025 amounts. Dependent credit ($100 per child under 17) not modelled. It also leaves out state additions and subtractions to federal AGI (such as retirement or Social Security exclusions), part-year and nonresident returns, and credits such as child care, earned income, and tax paid to another state.

### Which tax year do the Arizona rates cover?

The page uses 2025 amounts, because Arizona had not published 2026 amounts when this page was built. They come from Arizona Department of Revenue.

### Which states have no income tax on wages?

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. They have no page of their own, because there is no wage income tax to work out; the state income tax calculator answers 0 for them. Federal income tax and Social Security and Medicare still apply.

### Is this the same as my paycheck withholding?

No. This is the tax for the whole year on your return. Your employer withholds by the state's own withholding formula, so your refund or balance due is the difference between the two.
