Arizona taxpayers can give up to $506 (single or head of household) or $1,009 (married filing jointly) to a Qualifying Charitable Organization in 2026 and get every dollar back as a credit on their state income tax. It is one of the easiest ways to support a Tucson cause at no extra cost to you. TMM Family Services qualifies, and our QCO code is 20469.
If you have heard friends talk about “the Arizona tax credit” and never quite understood it, this guide walks through how it works, how much you can give and how to claim it.
At a glance:
- 2026 limit: $506 single / head of household, $1,009 married filing jointly
- Type: dollar-for-dollar credit, not a deduction
- Deadline: give by April 15, 2027 and still claim it for 2026
- Form: Arizona Form 321
- TMM’s QCO code: 20469
What is the Arizona Charitable Tax Credit?
Arizona allows you to direct part of the state income tax you already owe to a qualifying local charity. Instead of that money going only to the state, it goes to an organization that helps people in your community, and the state reduces your tax bill by the same amount.
Because it is a credit, it is different from a regular charitable deduction. A deduction lowers your taxable income. A credit lowers the tax itself, dollar for dollar.
How much can I give in 2026?
According to the Arizona Department of Revenue, the maximum Qualifying Charitable Organization (QCO) credit for 2026 is:
- $506 for single filers, heads of household and married filing separately
- $1,009 for married couples filing jointly
There is no minimum. A $25 gift qualifies just as much as a $500 gift.
What does that look like in real life?
Say you file jointly and owe $1,500 in Arizona income tax. If you give $1,009 to TMM Family Services and claim the credit, your Arizona tax due drops to $491. You spent the same $1,500 either way, but $1,009 of it stayed in Tucson to help a family find a stable home.
When is the deadline?
You can give any time during the calendar year. Arizona also allows gifts made from January 1 through April 15, 2027 to count toward your 2026 return. That gives you until Tax Day to make your decision, which is helpful if you want to see your tax picture first.
Can I also claim other Arizona tax credits?
Yes. The QCO credit is separate from the Qualifying Foster Care Charitable Organization (QFCO) credit and from the public and private school tax credits. Each has its own limit, so many Arizonans give to several causes in the same year.
