Arizona state income tax rate 2027.
Arizona’s flat rate from the official source, with the 2026 figures and a labelled projected 2027 column.
Short answer: Arizona taxes wages at a flat 2.5% for 2026 (a single bracket for single and joint filers). No different 2027 schedule is enacted yet, so the 2027 column carries the 2026 schedule forward and is labelled projected.

The Arizona schedule
ADOR Withholding Tax - Individual page: 'for tax year 2023 and beyond, the tax rate for Arizona taxable income is 2.5%.' ADOR 2026 Form 140ES: 'For tax year 2026 estimated tax payments, the tax rate for estimating your tax liability is 2.5%.' Flat, same for all filing statuses.
Single filers
| Taxable income | Rate, 2026 | Rate, 2027 (projected) |
|---|---|---|
| All taxable income | 2.5% | 2.5% |
Joint filers
| Taxable income | Rate, 2026 | Rate, 2027 (projected) |
|---|---|---|
| All taxable income | 2.5% | 2.5% |
Deductions, exemptions and local tax
Arizona’s standard deduction, exemption and credit amounts are not stated here because they were not read from the Arizona tax agency’s own pages on November 9, 2026. Use the state’s current return instructions. None of them is modelled.

What changes in 2027 (projected)
The Arizona Department of Revenue states that 2.5% applies for tax year 2023 and beyond, so the 2027 column carries it forward. No different 2027 rate was found.
The 2027 column above carries the 2026 schedule forward. That is a projection, not an enacted 2027 schedule, and it is labelled that way wherever it appears.
Worked example (2026 schedule)
A single filer with $80,000 of Arizona taxable income owes $2,000 under the 2026 schedule, an effective rate of 2.50% and a marginal rate of 2.5%. A joint filer with $150,000 of Arizona taxable income owes $3,750 under the 2026 schedule, an effective rate of 2.50% and a marginal rate of 2.5%. The 2027 projection for the same incomes is the same dollar amount ($2,000 and $3,750) because the 2026 schedule is carried forward.
Common mix-ups
- Arizona still has graduated brackets from 2.59% to 4.50%. Those are older schedules still displayed on the azleg.gov 43-1011 page; ADOR states the rate is a flat 2.5% for tax year 2023 and beyond.
- Arizona withholding choices (0.5% to 3.5%) are the tax rate. They are employee withholding elections; the tax rate is 2.5%, and the default withholding when no Form A-4 is filed is 2.0% per ADOR.
- Joint filers use different brackets. With one flat 2.5% rate, filing status does not change the rate.
Method
The tool applies each bracket rate only to the slice of income inside that bracket, adds the slices and divides by income for the effective rate; the marginal rate is the rate of the bracket that contains your income. The 2027 line uses the 2026 schedule and is shown as projected. Nothing you type is sent to our servers; the maths runs in your browser. For a full paycheck including federal and payroll taxes, use the paycheck calculator, and for comparing states see the state income tax calculator.

Frequently asked questions
What is the Arizona state income tax rate for 2027?
Arizona has not enacted a different 2027 schedule that this page could read, so the 2027 figures are projected by carrying forward the 2026 rate (2.5%).
What is the top Arizona income tax rate?
2.5% under the 2026 schedule. It applies to all taxable income; there is only one bracket.
How much Arizona income tax would I pay on $80,000?

Does this page include deductions or credits?
No. It applies the rate schedule to the taxable income you enter, so subtract your deductions and exemptions first. It does not model credits, local taxes or surtaxes.
Is the 2027 result a forecast?
It is a projection. It carries the 2026 schedule forward and is labelled projected wherever it appears. Arizona can change its rates or indexed brackets before the 2027 forms are issued.
Where does the information on this page come from?
Arizona sources read on November 9, 2026: ADOR Withholding Tax - Individual; ADOR 2026 Form 140ES; ARS 43-1011. The links in the Sources section go to the originals.
Why is my Arizona paycheck withholding not 2.5%?
Withholding is chosen on Form A-4 from 0.5% to 3.5% in half-point steps (default 2.0%); the final tax is settled at 2.5% on the return.
Not legal or tax advice
Rates change and this is an unofficial guide, not run by any state tax agency; any 2027 figure that is not enacted is a projection. Nothing you type is transmitted anywhere. Confirm with the Arizona tax agency or a tax professional before you file.
