Arizona's 2026 state standard deduction is an estimated $13,850 for single filers, $27,700 for married couples filing jointly, and $20,800 for heads of household. The standard deduction lowers the income Arizona taxes, so you only pay state tax on income above these amounts unless itemizing produces a larger deduction.
| Filing status | Standard deduction |
|---|---|
| Single | $13,850 |
| Married filing jointly | $27,700 |
| Head of household | $20,800 |
Your Arizona standard deduction is subtracted from your state taxable income before the tax rate is applied. You take either the standard deduction or your total itemized deductions — whichever is larger. Most households take the standard deduction because it exceeds their itemizable expenses.
