Arizona State-Specific Tax Details (2026)
Pass-Through Entity (PTE) Tax Election
Arizona offers an elective Pass-Through Entity (PTE) tax under A.R.S. 43-1014 for partnerships and S corporations, effective tax years from and after Dec 31, 2021. The entity pays at the highest individual rate, which equals Arizona's flat 2.5% for 2026. Owners receive a refundable Arizona credit for their share, letting the SALT cost be deducted federally at the entity level. The election is made annually on or before the (extended) due date of the AZ return; before electing, the entity must notify all partners/shareholders and give them 60 days to opt out.
Local & City Income Taxes
None. Arizona has no local, city, or county income tax. Cities and counties instead levy a Transaction Privilege Tax (TPT) — a gross-receipts-style tax imposed on the seller for the privilege of doing business — under the Model City Tax Code, which is a sales/business-activity tax, not an income tax.
Entity-Level & Franchise Taxes
Arizona has no franchise tax, no gross-receipts income tax, and no margin/B&O tax. It conforms to the federal S-corp election (S corps are pass-through and file Form 120S). The only entity-level option is the elective 2.5% PTE tax (A.R.S. 43-1014). C corporations pay a flat 4.9% corporate income tax for 2026, subject to a $50 minimum tax.
Arizona Tax Credits & Incentives
Income tax credit equal to 24% of the first $2.5M of qualifying Arizona research expenses plus 15% of qualifying expenses above $2.5M. The nonrefundable portion is administered by AZDOR (Form 308); businesses with fewer than 150 full-time employees may, with an Arizona Commerce Authority Certificate of Qualification, elect to have 75% of the excess (otherwise nonrefundable) credit refunded in cash. The refundable portion is subject to an annual statewide aggregate cap administered by the ACA — confirm the current cap amount with the ACA before relying on a specific dollar figure.
Up to $9,000 of income/premium tax credit per net-new qualifying job ($3,000 per year over three years) for businesses meeting capital-investment and county-median-wage thresholds. Administered by the Arizona Commerce Authority under A.R.S. 41-1525; the program is capped at funding 10,000 new jobs statewide per calendar year, with unused credit carried forward up to five years.
Income tax credit (A.R.S. 43-1074.02) for qualified investors who make certified equity investments in Arizona small businesses. Administered via certification through the Arizona Commerce Authority and claimed on AZDOR Form 338; available to individuals and pass-through owners (C corporations are ineligible).
Consider Arizona's separate Small Business Income (SBI) election (Form 140-SBI): an individual owner can carve qualifying business income off the regular Form 140 and report it on a separate return taxed at the SBI rate, which is 2.5% for 2025 and beyond under A.R.S. 43-1711. Because Arizona's regular individual rate is also a flat 2.5%, the SBI election rarely lowers the headline rate today, but it can simplify certain credit/deduction interactions — model it both ways with an Arizona tax professional before defaulting to the standard return.
Top Tax Strategies for Arizona Business Owners
Arizona offers a moderate tax environment. While state taxes are manageable, combining federal and state strategies can still save you thousands each year.
Flat 2.5% rate simplifies planning
S-Corp salary optimization

S-Corp Election in Arizona
For Arizona business owners with net income above $50,000, electing S-Corp status can save $5,000 to $20,000+ annually in self-employment taxes. As an S-Corp, you pay yourself a "reasonable salary" and take the remaining profits as distributions, which are not subject to the 15.3% self-employment tax. Keep in mind that Arizona's 2.5% flat income tax still applies to both your salary and your distributions, so the S-Corp election saves you federal self-employment tax while your state planning shifts to deductions, retirement contributions.
Example: A Phoenix S-Corp
A Phoenix business owner earning $150,000 in net business income pays themselves a reasonable salary of $60,000. The remaining $90,000 in distributions avoids the 15.3% SE tax, saving $13,770 in self-employment taxes alone — on top of whatever your Arizona state planning adds.
Retirement Plan Strategies for Arizona
Retirement plan contributions are the single most powerful tax deduction available to Arizona business owners. A Solo 401(k) allows contributions up to $69,000 in 2026 ($76,500 if you're 50+), generating tax savings of $17,000 to $24,000 at a 25-32% effective tax rate. For Arizona owners, those contributions cut both your federal bill and your 2.5% flat state income tax, stacking the savings.
SALT Deduction Impact in Arizona
Low SALT impact due to the flat 2.5% rate. The federal SALT (State and Local Tax) deduction cap increases from $10,000 to $40,000 in 2026, providing meaningful relief for business owners in states with income taxes.
