Arizona has become one of the more tax-competitive states in the Sun Belt after collapsing its income tax into a flat 2.50% rate in 2023. Combined with moderate property taxes, no tax on Social Security, and a growing economy anchored by Phoenix and the semiconductor industry, Arizona draws retirees, remote workers, and relocating businesses. The state’s transaction privilege tax (its version of sales tax) does add complexity for business owners.
Arizona Income Tax Rates (2026)
Arizona uses a flat income tax rate:
| Tax Rate | Taxable Income Range |
|---|---|
| 2.50% | All taxable income |
Arizona previously had a multi-bracket progressive system with rates up to 4.50%. Proposition 208 added a 3.50% surcharge on high earners, but court rulings and legislative action resulted in the current flat rate of 2.50%, which took effect in 2023.
Arizona conforms to the federal standard deduction amounts: ~$15,000 for single filers and ~$30,000 for married filing jointly for 2026.
Sales Tax
Arizona uses a Transaction Privilege Tax (TPT) rather than a traditional sales tax. The tax is technically on the seller’s privilege of doing business, not on the buyer, though it is passed through to consumers.
| Component | Rate |
|---|---|
| State base rate | 5.60% |
| Average combined (state + county + city) | ~8.40% |
| Highest combined rate | ~11.20% (in some jurisdictions) |
TPT rates vary significantly by city and county. Phoenix charges ~8.60% combined, while Scottsdale is ~7.95% and Tucson is ~8.70%.
Exempt from TPT: Most groceries (food for home consumption), prescription medications, and medical devices.
Property Tax
| Metric | Amount |
|---|---|
| Average effective rate | ~0.55% |
| National average | 0.99% |
Arizona property taxes are well below the national average. Properties are classified by use: residential owner-occupied properties have a lower assessment ratio (~10% of full cash value) than commercial properties (~18%).
Example: A home with a full cash value of $400,000 has an assessed value of ~$40,000. At a typical tax rate of ~$12 per $100 of assessed value, annual property tax is approximately ~$4,800 — or about 1.20% of assessed value but only ~0.55% of full market value.
Homeowner rebate: A state property tax credit is available for low-income homeowners and renters aged 65+ or on disability.
