How Arizona State Income Tax Works

Arizona has one of the most straightforward and lowest state income taxes in the US — a flat 2.5% rateon all taxable income. The rate took effect January 1, 2023, replacing Arizona's prior graduated structure that had a top rate of 4.5%. Arizona calculates state tax as follows:

1. Start with federal adjusted gross income (AGI) — Arizona uses federal AGI as its starting point, with minor state-specific adjustments.
2. Apply the standard deduction — Arizona conforms to the federal standard deduction: $14,600 for single filers, $29,200 for married filing jointly in 2026.
3. Multiply by 2.5% — the flat rate applies to Arizona taxable income after the deduction.

Arizona's Tax Rate History

Arizona dramatically cut its income tax in 2023, moving from a graduated structure (top rate 4.5%) to a single flat rate of 2.5%. The change was driven by HB 1828 and SB 1827 passed by the Arizona Legislature. For a single filer earning $100,000, this change saved approximately $2,000 per year compared to the prior structure. Proposition 132, also passed in 2022, now requires a 60% voter supermajority to raise income tax rates.

Federal Income Tax — Progressive Brackets

On top of the flat Arizona state tax, every Arizona worker owes federal income tax based on the 2026 progressive brackets ranging from 10% to 37%.

Step-by-Step Example — $70,000 Single Filer in Arizona

1. Gross annual pay: $70,000
2. Federal taxable income: $70,000 − $16,100 standard deduction = $53,900. Federal income tax (10%/12%/22% brackets): ≈ $5,765.
3. Arizona taxable income: $70,000 − $14,600 standard deduction = $55,400. AZ tax at 2.5%: ≈ $1,385.
4. FICA: 7.65% × $70,000 = $5,355.
5. Estimated net take-home: ≈ $57,495/year (≈ $2,211 biweekly).

FICA Taxes — Social Security and Medicare

• Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you cross the wage base for the year.
• Medicare: 1.45% on all wages with no cap. Additional 0.9% Medicare surtax on wages above $200,000 single / $250,000 MFJ.
• Employer match: your employer matches Social Security and base Medicare; the Additional Medicare surtax is employee-only.

No Local Income Tax in Arizona

Arizona has no local or city payroll income tax statewide. Phoenix, Tucson, Scottsdale, Chandler, Gilbert, and all other Arizona municipalities do not levy a local income tax on residents or employees. Arizona cities collect revenue primarily through sales taxes and property taxes. The Arizona Transaction Privilege Tax (TPT) is a business sales tax, not an individual income or payroll tax, and is not reflected in employee paychecks.

Arizona vs. Neighboring States

• vs. Colorado:Colorado's 4.4% flat rate costs significantly more than Arizona's 2.5%. A $100,000 earner saves about $1,900 per year in state income tax in Arizona vs. Colorado.
• vs. Nevada: Nevada has no state income tax. Arizona's 2.5% rate costs roughly $2,085 per year for a $100,000 earner compared to $0 in Nevada, but Arizona offers better public services and infrastructure.
• vs. California:California's progressive rates range from 1% to 13.3%. A California single filer earning $100,000 owes about $6,600–$7,000 in state tax — three times more than in Arizona.
• vs. New Mexico: NM has progressive brackets up to 5.9%, making Arizona substantially cheaper for most income levels.

How to Maximize Your Arizona Take-Home Pay

• Max your 401(k) — pre-tax 401(k) contributions reduce both federal and Arizona taxable income. At 2.5% AZ + 22% federal = 24.5% combined marginal rate, a $20,000 contribution saves about $4,900 per year.
• Contribute to an HSA — $4,300 (self-only) or $8,550 (family) for 2026. Arizona recognizes HSA contributions as pre-tax.
• Use a Dependent Care FSA — up to $5,000 per family reduces both federal and Arizona taxable income for qualifying childcare or elder care.
• Adjust Arizona Form A-4— Arizona's state withholding form (A-4) allows you to specify a flat-dollar withholding percentage. Employees can choose a withholding percentage (0.5%–3.2% of gross wages) to match their expected liability. Update whenever your situation changes.
• Arizona 529 plan — Arizona residents can deduct 529 college savings contributions from Arizona taxable income (up to $4,000 per beneficiary per year for single filers, $8,000 for married filers), generating small additional state tax savings.
