ARIZONA INCOME TAX IN 2026 — THE NATION'S LOWEST FLAT RATE
Among the 41 US states that levy a broad-based income tax on wages, Arizona holds an unusual distinction: it charges the lowest flat income tax rate of any of them — just 2.5% on Arizona taxable income. That single number replaced a five-bracket graduated system as recently as 2023, making Arizona's income tax transformation one of the most dramatic in modern state tax history. A worker in Phoenix, Tucson, or Flagstaff who was paying up to 4.5% on their top dollar of income in 2022 now pays 2.5% on every dollar above the standard deduction — a cut of 2 full percentage points at the top of the prior schedule.
Arizona also keeps its paycheck deduction structure lean: four lines total, with no state disability insurance, no paid family leave surcharge, and no local income tax anywhere in the state. The same formula applies uniformly from metro Phoenix to the rural White Mountains — no county or city surcharges complicate the calculation.

EVERY DEDUCTION ON AN ARIZONA PAYCHECK IN 2026
Arizona paychecks carry four deduction lines — the same minimal set regardless of whether you work in downtown Phoenix, rural Yuma, or the Navajo Nation border counties:
- Federal Income Tax — The 2026 progressive federal schedule from 10% to 37%, applied after the $15,000 federal standard deduction (Single) reduces taxable income. Federal tax is the largest withholding on a typical Arizona paycheck — the flat 2.5% state tax is deliberately kept smaller than nearly every bracket of federal tax.
- Social Security — 6.2% on wages up to the $176,100 annual ceiling (2026). Wages above this point are exempt from Social Security withholding for the rest of the calendar year.
- Medicare — 1.45% on all wages with no cap. An additional 0.9% applies on individual wages above $200,000 (not employer-matched).
- Arizona State Income Tax — A flat 2.5% on all Arizona taxable income. Arizona taxable income equals gross wages minus the Arizona standard deduction — the same amounts as the federal standard deduction. No personal exemption applies for standard filers; the standard deduction is the sole pre-tax reduction before the 2.5% rate applies.
ARIZONA'S FLAT TAX — THE SIMPLEST CALCULATION IN THIS SERIES
Arizona's state income tax calculation is the most straightforward of any income-tax state in this entire series. There are no bracket thresholds to traverse, no phased credits, no complex deduction formulas, and no local surtaxes — just a single multiplication:
AZ Taxable = $70,000 − $15,000 (standard deduction) = $55,000
$55,000 × 2.5% = $1,375.00
For MFJ filers, the $30,000 standard deduction doubles the shelter and cuts the taxable base commensurately. For HOH filers, the $22,500 deduction provides intermediate shelter. In every case, the math is a single step after the deduction is applied.
Because Arizona taxable income uses the same standard deduction amounts as federal taxable income — and has no separate personal exemption — Arizona and federal taxable income are identical for the overwhelming majority of standard-deduction filers. The only difference is the rate applied: federal progressive brackets versus Arizona's flat 2.5%.
ARIZONA INCOME TAX BY SALARY LEVEL — 2026
| Gross Salary (Single) | AZ Taxable Income | AZ State Tax (2.5%) | Effective Rate on Gross | Est. Annual Net |
|---|---|---|---|---|
| $40,000 | $25,000 | $625 | 1.56% | ~$33,554 |
| $55,000 | $40,000 | $1,000 | 1.82% | ~$45,231 |
| $70,000 | $55,000 | $1,375 | 1.96% | ~$56,256 |
| $100,000 | $85,000 | $2,125 | 2.13% | ~$76,611 |
| $150,000 | $135,000 | $3,375 | 2.25% | ~$109,903 |
| $200,000 | $185,000 | $4,625 | 2.31% | ~$144,310 |
| $250,000 | $235,000 | $5,875 | 2.35% | ~$176,869 |
The effective rate on gross income rises smoothly toward 2.5% as salary increases — it never quite reaches 2.5% because the standard deduction permanently shelters $15,000 of gross income. At $250,000, the effective rate reaches 2.35%. At $1,000,000, it would reach 2.46%. The flat structure means every dollar of additional income above the standard deduction is taxed at exactly the same 2.5% — Arizona has no bracket penalty for earning more.
ARIZONA VS NEIGHBORS — FULL TAKE-HOME COMPARISON AT $70,000
Arizona's 2.5% flat rate produces the highest take-home pay of any income-tax state at the $70,000 Single benchmark. The only states with better take-home outcomes are those with no income tax at all:
| State | Income Tax Structure | State Tax on $70k (Single) | Est. Annual Net | vs Arizona |
|---|---|---|---|---|
| Nevada | No state income tax | $0 | ~$57,631 | +$1,375 |
| Wyoming | No state income tax | $0 | ~$57,631 | +$1,375 |
| Texas | No state income tax | $0 | ~$57,631 | +$1,375 |
| Arizona | Flat 2.5% | $1,375 | ~$56,256 | — |
| Colorado | Flat 4.4% | ~$2,420 | ~$55,211 | −$1,045 |
| Idaho | 1.125%/5.695% | $2,826 | ~$54,805 | −$1,451 |
| Utah | Flat 4.55% | ~$3,025 | ~$54,606 | −$1,650 |
| New Mexico | Progressive to 5.9% | ~$2,220 | ~$55,411 | −$845 |
| California | Progressive to 13.3% | ~$3,859 | ~$53,772 | −$2,484 |
| Oregon | Progressive to 9.9% | ~$4,963 | ~$52,598 | −$3,658 |
Arizona's $1,375 state tax bill is exactly $3,658 less per year than Oregon's at the same salary — a gap that compounds dramatically over a working career. Over 30 years at $70,000, the cumulative difference between Arizona and Oregon in state income tax alone exceeds $109,000. Compared to California, the gap at $70,000 is $2,484 per year — over 30 years, more than $74,000 in total additional California state income taxes paid on the same earnings.
ARIZONA'S FLAT TAX VERSUS ITS OWN HISTORY
The pace of Arizona's income tax reduction is unusual even among reform-oriented states. The state went from a five-bracket system to a single flat rate in just two years — and that flat rate at 2.5% undercuts virtually every other reform state:
| Tax Year | Top Rate / Structure | AZ State Tax on $70k Single | Annual Saving vs 2022 |
|---|---|---|---|
| 2020 | 5-bracket, top 4.54% | ~$1,461 | — |
| 2021 | 5-bracket, top 4.54% | ~$1,457 | — |
| 2022 | 3-bracket, top 4.5% (SB 1828 phase-in) | ~$1,622 | (baseline) |
| 2023 – 2026 | Flat 2.5% (SB 1828 full effect) | $1,375 | +$247/yr |
The 2022 intermediate year actually produced a higher tax bill than 2021 for some income levels, because the transitional bracket consolidation eliminated some lower rates before the full flat 2.5% kicked in. The full benefit of SB 1828 was realized in 2023 when the flat rate replaced the transitional schedule, and that $247 annual saving at $70,000 Single has been sustained through 2026 with no intervening changes.
NO LOCAL INCOME TAX — STATEWIDE UNIFORMITY
Arizona is one of the few Sun Belt states to explicitly prohibit cities and counties from levying their own income taxes on wages. Phoenix, Tucson, Mesa, Chandler, Scottsdale, Gilbert, Glendale, Tempe, and every other Arizona municipality operate with the same state-only income tax framework — no city income tax surcharge, no county payroll levy. This is a contrast to states like Ohio (where Columbus, Cleveland, and Akron all levy local income taxes of 2%–2.75%), Maryland (where every county levies a local rate of 2.25%–3.2%), and Kentucky (where Louisville, Lexington, and Covington each impose occupational taxes on wages).
The no-local-tax rule means an Arizona worker's take-home pay is identical whether they live in Phoenix or in a small rural community — the same four deductions, the same flat 2.5%, the same result.

ARIZONA PAYCHECK CALCULATOR FAQs
What is Arizona's income tax rate in 2026?
Arizona has a flat income tax rate of 2.5% on all Arizona taxable income — the lowest flat rate of any US state with an income tax. This rate has been in effect since January 1, 2023, following SB 1828 (2021), which replaced Arizona's prior five-bracket system. No surcharges, no local income taxes, and no filing-status-dependent bracket variation — every Arizona filer pays 2.5% on their taxable income.
What comes out of an Arizona paycheck in 2026?
Four deductions: federal income tax (10%–37%), Social Security at 6.2% up to $176,100, Medicare at 1.45%, and Arizona state income tax at a flat 2.5%. No Arizona SDI, TDI, PFML, transit tax, or local income tax of any kind.
What is Arizona's standard deduction in 2026?
Arizona mirrors the federal standard deduction: $15,000 for Single filers, $30,000 for MFJ, $22,500 for HOH. There is no additional personal exemption for standard filers. Arizona and federal taxable income are therefore identical for standard-deduction filers — only the rate differs (2.5% state versus progressive federal brackets).
How much will I take home on a $70,000 salary in Arizona?
Filing Single on $70,000 in Arizona: AZ taxable income is $55,000 after the $15,000 standard deduction. State tax = $55,000 × 2.5% = $1,375. Combined with $7,014 federal income tax and $5,355 FICA, annual take-home is approximately $56,256 — or about $4,688 per month. This is the highest take-home of any income-tax state in this series at $70,000 Single.
What is Proposition 208 and does it affect my paycheck in 2026?
Proposition 208 was a 2020 Arizona ballot measure that passed narrowly and would have added a 3.5% education surcharge on income above $250,000 (Single) and $500,000 (MFJ). It was struck down by the Arizona Supreme Court in August 2022 as inconsistent with the income tax cap established by SB 1828. Prop 208 has no effect on any Arizona paycheck in 2026 — the uniform 2.5% flat rate applies to all filers at all income levels.
Does Arizona have a local income tax?
No. Arizona cities and counties are prohibited from levying income taxes on wages. Phoenix, Tucson, Scottsdale, Mesa, Chandler, Tempe, Gilbert, and every other Arizona municipality collect no wage income taxes. Workers across the state pay only the uniform statewide 2.5% rate.
