How it works

How the Arizona Paycheck Calculator Formula Works

Start from gross annual salary and subtract four things in sequence: federal income tax on the 2026 brackets after the federal standard deduction, Arizona state income tax at a single flat 2.5% rate after Arizona's own standard deduction, and the two FICA taxes — 6.2% Social Security up to the year's wage base and 1.45% Medicare with no cap.

Arizona has taxed every resident at the same flat rate since 2023, so unlike a bracketed state, there is no marginal-rate calculation for the state line — it's the flat rate applied once to taxable income after the deduction. Arizona's standard deduction is set by state statute to grow every year using the same inflation-adjustment method the federal standard deduction uses, and has matched the federal dollar amount exactly since Arizona adopted this conformity in 2019.

What this figure does not include: a 2025 bill that would have cut Arizona's rate further, to 2.42% for 2026, did not pass, so the rate below reflects the actual enacted 2.5% rate rather than a proposal that never became law.

netPay = gross − federalTax(2026 brackets) − azStateTax(2.5% flat) − socialSecurity(6.2% to $184,500) − medicare(1.45% + 0.9% above threshold)

Worked example

A Real Worked Example

A single filer earning $75,000 a year in Arizona, paid biweekly, owes $7,670 in federal tax after the $16,100 federal standard deduction, $1,472.50 in Arizona state tax after Arizona's own $16,100 standard deduction taxed at the flat 2.5% rate, $4,650 in Social Security, and $1,087.50 in Medicare — $14,880 total, leaving $60,120 a year or $2,312.31 per biweekly paycheck.

Switch the same $75,000 salary to married filing jointly and federal tax drops to $4,640 and Arizona tax drops to $1,070, because both standard deductions roughly double while the 2.5% rate itself stays exactly the same for every filing status. FICA is unaffected by filing status, so the married filer's total tax bill falls to $11,447.50 and take-home pay rises to $63,552.50 a year, or $2,444.33 per biweekly paycheck — about $3,432 more per year than the single filer at the identical salary.

What Else to Know

Arizona's flat 2.5% rate — the lowest of any state that taxes wages

Arizona replaced its former graduated bracket system with a single flat individual income tax rate of 2.5%, effective for tax year 2023 and continuing through 2026. Every dollar of Arizona taxable income, for every filer regardless of total earnings, is taxed at this one rate — there is no marginal-bracket calculation the way there is in a state like Virginia or New York.

That 2.5% figure makes Arizona the lowest flat individual income tax rate among all states that impose one at all, a genuinely notable distinction rather than a marketing talking point: most flat-tax states sit meaningfully higher, and most graduated-bracket states have top rates several times this level.

A 2025 legislative proposal (SB1318) would have cut the rate further, to roughly 2.42% for 2026, through a formula tied to the state's budget surplus each year. That bill did not pass, and Arizona's own 2026 estimated-tax forms confirm 2.5% remains the rate in effect — this calculator uses that confirmed, enacted figure rather than the proposal that never became law.

Why Arizona's standard deduction moves in lockstep with the federal figure

Arizona's standard deduction is not set independently the way New York's or Virginia's is. State statute requires the Arizona Department of Revenue to adjust the dollar amount every year using the exact same inflation-adjustment method the federal standard deduction uses under the Internal Revenue Code — a conformity rule adopted in 2019 when Arizona overhauled its individual income tax.

The practical effect: Arizona's standard deduction has tracked the federal amount dollar-for-dollar in recent years, and for 2026 that puts it at $16,100 for single filers and $32,200 for married filing jointly — identical to the federal figures this calculator's federal-tax line already uses. That is a coincidence of matching methodology, not a rule that Arizona simply copies whatever number the IRS publishes each year, though in practice the result has been the same number.

Because the standard deduction is the only variable that changes by filing status here, a married couple's Arizona tax liability at the same combined income as two single filers depends entirely on that larger deduction, not on any difference in the flat rate itself.

What this calculator does not include

This calculator applies Arizona's confirmed 2026 flat rate and standard deduction to a regular annual salary — it does not model Arizona's optional charitable-contribution addition to the standard deduction (available to filers who take the standard deduction rather than itemizing, capped at $1,000 for single filers), city-level transaction privilege tax on purchases, or any credits a specific filer might claim on their actual return.

It also does not attempt to project what happens if a future legislative session revives a rate-cut proposal like the one that failed in 2025, or a future surplus year triggers a different formula — this calculator reflects the rate actually in effect for tax year 2026, and will need updating if that changes.

As with every state page in this series, treat the result as an estimate of statutory withholding on a flat salary, not a substitute for an actual tax return that accounts for a specific filer's full financial picture, additional income sources, or itemized deductions instead of the standard one.

It also doesn't model the actual mechanics of Arizona payroll withholding, which works differently from the 2.5% liability figure above: employees choose a withholding percentage of gross wages on Arizona Form A-4, so the amount actually withheld from a given paycheck can be higher or lower than the annual liability this calculator estimates until it's reconciled on the annual return.

Questions

Frequently Asked Questions About the Arizona Paycheck Calculator

What is Arizona's state income tax rate for 2026?

A single flat rate of 2.5% on Arizona taxable income, for every filer regardless of income level or filing status. Arizona moved to this flat-rate system starting in tax year 2023, replacing its previous graduated brackets, and 2.5% is the lowest flat individual income tax rate of any state that taxes wage income at all.

How much is Arizona's standard deduction in 2026?

$16,100 for single filers and those married filing separately, $32,200 for married filing jointly — identical to the federal standard deduction for 2026. Arizona statute requires its own deduction to grow each year using the same inflation-adjustment method as the federal figure, and the two amounts have matched dollar-for-dollar since Arizona adopted this conformity rule in 2019.

Was Arizona's tax rate cut below 2.5% for 2026?

No. A 2025 bill (SB1318) would have required a further cut, to about 2.42%, triggered by a state budget surplus formula — but it did not pass the legislature. Arizona's Department of Revenue confirms 2.5% as the rate to use for 2026 estimated tax payments, so this calculator uses the actual enacted rate rather than a proposal that never became law.

Do Arizona's tax rates differ for single and married filers?

No — the 2.5% rate itself is identical for every filing status. Only the standard deduction changes: $16,100 for single filers versus $32,200 for married filing jointly, mirroring the same ratio as the federal standard deduction Arizona's amount is tied to. A married couple simply shields more income from the flat rate, not a different rate.

Is Social Security tax capped in Arizona?

Yes, but the cap is federal, not an Arizona rule. Social Security tax is 6.2% of wages up to $184,500 for 2026, after which no more Social Security tax is withheld for the rest of the year regardless of state. Medicare's 1.45% has no cap at all, and earners above $200,000 (single) or $250,000 (married filing jointly) pay an extra 0.9% Additional Medicare Tax on the excess.

Why does Arizona have such a low income tax rate?

Arizona phased in a series of rate cuts culminating in a single flat 2.5% rate for tax year 2023 and after, part of a broader legislative push to simplify the state's tax code and lower its rate relative to neighboring states. It remains the lowest flat individual income tax rate among all states that tax wage income, though several no-income-tax states still tax wages less overall.

How does this differ from my actual Arizona tax bill?

This calculator estimates statutory withholding on regular wages using Arizona's 2026 flat rate and standard deduction — it does not account for Arizona-specific credits (such as the charitable-contribution addition to the standard deduction), pre-tax deductions like a 401(k) or health premiums, or additional income that would change total taxable income. Your actual return may differ from this estimate for any of those reasons.

What pay frequencies does this calculator support?

Weekly (52 paychecks a year), biweekly (26), semimonthly (24), monthly (12), or a single annual payment. Choosing a pay frequency doesn't change the total annual tax owed — federal tax, Arizona's flat 2.5% state tax, and FICA are all calculated on the full annual salary first — it only changes how that same annual total is divided into a per-paycheck take-home figure.

Why doesn't my paycheck match the flat 2.5% rate?

Arizona employers don't withhold at the 2.5% liability rate directly each pay period. Instead, state law has each employee choose a withholding percentage of gross taxable wages on Form A-4, Arizona's own version of the federal W-4, with the exact percentage options and the default for anyone who never files the form set administratively by the Department of Revenue. That means two coworkers earning the same salary can see different amounts withheld if they chose different Form A-4 percentages, and any gap between actual withholding and this calculator's 2.5% liability estimate typically evens out as a refund or balance due when the annual return is filed.
