Arizona offers one of the most valuable state tax benefits available to individuals: the Charitable Tax Credit (claimed on Form 321). This credit lets you reduce your Arizona income tax dollar-for-dollar by donating to Qualifying Charitable Organizations (QCOs).
2026 Credit Limits
- Single, Married Filing Separately, or Head of Household: Up to $506
- Married Filing Jointly: Up to $1,009
These limits are higher than in previous years and are adjusted annually.
How the Credit Works
Unlike a regular charitable deduction (which only reduces your taxable income), this is a true tax credit. Every dollar you donate to a QCO reduces your Arizona tax liability by the same amount, up to the annual limit.
If your credit is larger than the tax you owe, you can carry the unused portion forward for up to five years.
Important Timing Rules
- Donations made in 2026 can be claimed on your 2026 Arizona return.
- Donations made between January 1 and April 15 of the following year can often be applied to the prior tax year (check current rules when you file).
- You must donate to an organization on the official Arizona Department of Revenue QCO list and keep the receipt that includes the organization’s 5-digit code.
Who Should Consider This Credit?
- Anyone who pays Arizona state income tax
- Taxpayers looking to support local charities while reducing their tax bill
- People who want a simple, high-impact way to lower their Arizona tax liability
