These updates reflect recent guidance from the Arizona Department of Revenue (ADOR), statutory adjustments, and updates to income tax credits, deductions and required schedules.
- Arizona Flat Income Tax Rate Remains at 2.5% – ADOR confirmed that Arizona continues its statewide flat individual income tax rate of 2.5% for 2026/27. No changes were made to the rate, and the structure for resident, part-year and nonresident filers remains unchanged.
- Updated Standard Deduction Amounts – Arizona increased its standard deduction for 2026/27 to align with inflation adjustments. These amounts flow through Forms 140, 140A, 140EZ, 140NR and 140PY. The charitable-contribution-based SD increase (0.33 multiplier) continues unchanged.
- Clarified Long-Term Capital Gain Subtraction Rules – ADOR reiterated that the 25% Arizona subtraction applies only to net long-term capital gains derived from Arizona sources. Updated worksheets and guidance appear in Schedule A for Forms 140 Schedule A, 140NR Schedule A(NR) and 140PY Schedule A(PY).

- Revised Instructions for Nonresident & Part-Year Allocation – ADOR issued new guidance clarifying allocation of income for nonresidents and part-year residents.

Frequently Asked Questions
How does the Arizona tax rate apply on Form 140EZ?
Form 140EZ uses the same statewide flat tax rate that applies to all Arizona resident income tax returns. The rate is applied to taxable income after subtracting the standard deduction. Because the EZ form does not allow deductions, adjustments, or specialized exemptions, the calculation is straightforward and consistent across all taxpayers who qualify. While simplified, taxpayers may still benefit from comparing outcomes with Form 140A or Form 140 if their income or credit situations are more nuanced.
How are medical deductions handled for part-year residents on Schedule A(PY)?
Medical deductions follow the federal rule requiring expenses to exceed 7.5% of federal AGI before any amount becomes deductible. Because AGI is based on the full tax year—even for part-year residents—this threshold affects how much of the medical deduction flows into Arizona’s calculation. Once the federal deduction amount is entered on the schedule, Arizona applies its own rules, makes any required adjustments, and only then prorates the remaining allowable deduction by the part-year ratio.
Can I claim Form 323 alongside other Arizona tax credits?
Yes. Arizona allows taxpayers to claim multiple credits in the same year—including QCO credits (Form 321), QFCO credits (Form 348), private school tuition credits (Form 322), and switcher credits. Each credit has independent limits. Many taxpayers stack these credits to maximize their tax benefit while supporting different educational and charitable institutions across the state.
Are employer unemployment or state payroll taxes shown?
No—those are employer liabilities; your take-home shows only employee withholdings.
How does Arizona define “household income” for purposes of Form 140ET?
Household income includes all income received by every household member—wages, pensions, Social Security benefits, interest, dividends and any other taxable or nontaxable amounts required under Arizona rules. Unlike the federal return, Arizona applies excise-credit eligibility based on combined income rather than just the filer’s income. This prevents taxpayers from receiving relief credits when household earnings exceed eligibility limits. Taxpayers must be careful to include all income amounts accurately, as Arizona may cross-check against reported federal data or other state-maintained records.
