Posted by When you pay Arizona income tax, you normally have no say in where it goes. Arizona offers another option. Several state tax credits let you give to qualifying charities and schools, then lower your Arizona tax by the amount you gave, up to set limits.
A credit is not a deduction. A deduction lowers the income your tax is based on. A credit lowers the tax itself.
The Credits Most Families Use
Here are three common ones, with the 2026 limits from the Arizona Department of Revenue.
- Qualifying Charitable Organizations (QCO): up to $506 for single filers and $1,009 for married couples filing jointly. These charities serve low income Arizonans and people with a chronic illness or physical disability.
- Qualifying Foster Care Charitable Organizations (QFCO): up to $632 single and $1,262 married filing jointly.
- Public School Tax Credit: up to $200 single and $400 married filing jointly, for fees or gifts to a public school for eligible activities.
These are separate credits. You can claim more than one in the same year if you give to each type of organization. You can claim them whether you itemize or take the standard deduction.
Arizona also offers credits for gifts to certified School Tuition Organizations, which fund private school scholarships. Those have their own limits and forms.
Here is a simple example. Say you file single and give $506 to a qualifying food bank. If you owe at least that much in Arizona tax, your state tax drops by $506.
How the Timing Works
Arizona gives QCO and QFCO donors some extra time. A gift made by April 15 can count toward either that year or the year before.
There is a limit to that flexibility. If you apply an early year gift to the prior year, the prior year’s maximum applies. Giving by December 31 keeps things simple, because the gift and the credit line up in the same year. If you give in early 2027 and want the higher 2027 limit, you would claim it on your 2027 return instead. For more on fitting these credits into a year-end plan, see CapitalChoiceAZ.com.
The Paperwork That Makes It Count
A credit only works if you claim it correctly. Each certified QCO and QFCO has a five digit code that you enter on Form 321 or Form 352.
The QCO and QFCO credits are for cash gifts, not donated goods. Keep a receipt for each gift. If you itemize on your Arizona return, you can’t also deduct a gift you claim as a QCO or QFCO credit.
For public school gifts, you report the school’s nine digit CTDS number on Form 322. The money can support things like sports and clubs, character education, test fees, and CPR training. Keep the receipt from every gift with your tax records.
Check Your Tax Bill First
These credits are nonrefundable. They can lower your Arizona tax, but they won’t pay you back more than you owe. Before you give the maximum, look at last year’s Arizona return to see what you actually owed. If you owe less than the limit, any unused QCO or QFCO credit can carry forward for up to five years. Married couples filing jointly use the higher limits on one joint return.
Also confirm that the charity is on the current list. Only certified organizations qualify, and the list changes from year to year. You can check the codes and the current limits on the Arizona Department of Revenue’s QCO and QFCO page.
A Small Step With a Local Impact
For most people, that money was headed to the state anyway. What these credits change is where it goes. A few minutes before year-end can send part of your state tax to a food bank, a foster family program, or your neighborhood school.
Pick one group this year. Give before December 31, and save the receipt in your tax file. Next spring, the credit will be ready when you file.
