The Arizona qualified charitable organizations tax credit lets you reduce your state income tax, dollar for dollar, by donating cash to a nonprofit on the Arizona Department of Revenue’s certified QCO list. For the 2026 tax year, the maximum credit is $506 for single, head of household, or married filing separately, and $1,009 for married filing jointly.1State of Arizona State Employees Charitable Campaign. Tax Credit A credit is more valuable than a deduction because it comes straight off the tax you owe rather than off the income you’re taxed on.
Find the Organization on the Official List
The Arizona Department of Revenue (ADOR) publishes the certified list each year as a PDF titled “List of Qualifying Charitable Organizations for 2026.”2Arizona Department of Revenue. List of Qualifying Charitable Organizations for 2026 Every entry includes the organization’s name, address, and a unique five-digit QCO code. You need that code to claim the credit on your return, and matching the organization against the current year’s list is the only reliable way to confirm it still qualifies.
Check the list before you donate. An organization certified last year may not be certified this year, and a donation to a delisted charity won’t earn the credit. If a charity can’t give you its QCO code, verify with ADOR before contributing.3Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs
2026 Credit Amounts and Rules
For 2026, the maximum QCO credit is:1State of Arizona State Employees Charitable Campaign. Tax Credit
- Single, head of household, or married filing separately: $506
- Married filing jointly: $1,009
You can give more, but only the first $506 or $1,009 generates the credit. Only cash counts. Donating clothing, food, or other property to a QCO does not qualify, regardless of the goods’ value.4Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088
If your credit is larger than the Arizona tax you owe, the unused portion carries forward for up to five consecutive tax years. If you donate through an umbrella organization that collects money for member charities, you must designate a specific member that would independently qualify as a QCO.4Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088
You Can Still Donate for Last Year
A donation made between January 1 and the tax filing deadline (typically April 15) can be applied to either the current tax year or the preceding one. A February 2026 contribution can count on your 2025 return if you haven’t filed yet.3Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs If you apply a January-through-April gift to the prior year, don’t also claim it on your current-year return.
Stack the Foster Care Credit
Arizona runs a separate credit for Qualifying Foster Care Charitable Organizations (QFCOs), and you can claim both in the same year.4Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088 For 2026, QFCO limits are higher:3Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs
- Single, head of household, or married filing separately: $632
- Married filing jointly: $1,262
A married couple filing jointly who maxes out both credits could claim $2,271 against their Arizona tax. QFCOs have their own ADOR list and their own five-digit codes.5Arizona Department of Revenue. List of Qualifying Foster Care Charitable Organizations for 2026 A QCO code is not a QFCO code; the two credits are tracked separately.
How to Claim the Credit
Both credits are claimed on Arizona Form 321, “Credit for Contributions to Qualifying Charitable Organizations,” filed with your Arizona income tax return (usually Form 140). The form asks for each donation’s date, the organization’s name, and its five-digit code, then checks your total against the maximum for your filing status.3Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs
Form 321 also has sections for carry-forward amounts from earlier years. Keep prior-year copies on hand so you know exactly how much unused credit remains. You cannot take both the Arizona credit and an Arizona charitable deduction for the same contribution.4Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088 The credit is almost always the better outcome.
What the Credit Does to Your Federal Return
Because the QCO credit returns 100% of your donation, it exceeds the IRS’s 15% safe harbor. If you itemize on your federal return, you must reduce your federal charitable contribution deduction by the amount of the Arizona credit you received.6Internal Revenue Service. Publication 526, Charitable Contributions Donate $506, claim the full $506 state credit, and you can’t also deduct that $506 on federal Schedule A.
An IRS safe harbor lets you treat the lost charitable deduction as a state and local tax payment instead, which may help if you’re under the $10,000 SALT cap. If you take the federal standard deduction, none of this applies, and you keep the full Arizona credit with no federal offset.
Records to Keep
Get a written receipt from each QCO. It should show the organization’s name, the donation amount, the date, and whether you received any goods or services in return.7Internal Revenue Service. Charitable Contributions – Written Acknowledgments Most QCOs issue receipts automatically; if yours doesn’t, ask before year-end.
Save receipts, your completed Form 321, and the QCO list you used to verify the organization. The IRS generally wants records retained for three years from the return’s filing date, but a five-year carry-forward means you could need documentation seven or eight years back.8Internal Revenue Service. How Long Should I Keep Records Digital copies work, as long as they’re legible and backed up.
