Arizona Qualified Charitable Organizations are nonprofits certified by the Arizona Department of Revenue (ADOR) whose donors can claim a dollar-for-dollar state income tax credit for their contributions. For the 2026 tax year, that credit is capped at $506 for single filers and $1,009 for married couples filing jointly. Unlike a deduction, a credit reduces the tax you owe by the full donation amount. Arizona also runs a separate, stackable credit for Qualifying Foster Care Charitable Organizations, so a single household can claim both in the same year.
Finding the Official List and QCO Code
ADOR publishes the certified list on its tax credits page. The 2026 file is a PDF titled “List of Qualifying Charitable Organizations for 2026.”1Arizona Department of Revenue. List of Qualifying Charitable Organizations for 2026 Every entry shows the organization’s name, address, and a unique five-digit QCO code. You need that code to claim the credit.
Check the list for the tax year you plan to claim before you give. An organization certified last year may not be certified this year, and a donation to a delisted charity earns no credit. Search the PDF by name. If a charity can’t produce its QCO code, verify directly with ADOR before contributing.2Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs
What an Organization Must Do to Qualify
A QCO has to be either a federally tax-exempt 501(c)(3) nonprofit or a designated community action agency receiving Community Services Block Grant funds. On top of that, the organization must direct at least 50% of its budget to services for Arizona residents who fall into one of three groups: people receiving Temporary Assistance for Needy Families (TANF), low-income residents below 150% of the federal poverty level, or individuals with a chronic illness or physical disability.3Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088 The qualifying services are direct aid: food, temporary shelter, clothing, medical care.
The statute excludes any organization that provides, pays for, or covers abortions, or that financially supports another entity that does. Certified organizations must recertify annually with ADOR.3Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088
2026 Credit Amounts and Rules
The QCO credit is adjusted for inflation each year. For 2026:4State of Arizona State Employees Charitable Campaign. Tax Credit
- Single, head of household, or married filing separately: $506
- Married filing jointly: $1,009
You can donate more than the cap, but only the amount up to the cap generates a credit. Only cash contributions count. Donating clothing, food, or other property to a QCO does not qualify, no matter how valuable the goods are.3Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088
If your credit is larger than the Arizona income tax you owe, the unused portion carries forward for up to five consecutive tax years. The credit also replaces any state charitable deduction for the same donation; you cannot claim both on your Arizona return.3Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088
The Prior-Year Donation Window
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 year’s return. A contribution in February 2026 can count on your 2025 return if you haven’t filed yet.2Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs If you use a January-through-April donation on the prior year, adjust your current-year return so the same contribution isn’t counted twice.
The Foster Care Credit You Can Stack On Top
Arizona runs a separate credit for Qualifying Foster Care Charitable Organizations (QFCOs). You can claim both credits in the same year.3Arizona Legislature. Arizona Revised Statutes Title 43 – Section 43-1088 For 2026 the QFCO limits are higher:2Arizona 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 joint filer donating to both a QCO and a QFCO could claim up to $2,271 in combined credits. ADOR publishes a separate QFCO list with its own five-digit codes.5Arizona Department of Revenue. List of Qualifying Foster Care Charitable Organizations for 2026
Claiming the Credit on Your Return
Both credits are claimed on Arizona Form 321, “Credit for Contributions to Qualifying Charitable Organizations,” filed with your Arizona income tax return (typically Form 140). The form asks for the date of each donation, the name of the organization, and its five-digit QCO or QFCO code, then calculates the total against the cap for your filing status.2Arizona Department of Revenue. Credits for Contributions to QCOs and QFCOs
Form 321 also handles carry-forwards. If you had unused credit from an earlier year, enter that amount here to apply it against your current liability. Keep prior-year Form 321 copies so you can track exactly how much unused credit remains.
How the Federal Return Interacts
The Arizona QCO credit returns 100% of your donation, well above the IRS’s 15% safe harbor threshold. 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 Arizona credit, and you cannot also deduct that $506 on federal Schedule A. The IRS has issued a safe harbor letting you treat the disallowed charitable deduction as a state and local tax payment, which may help if you’re below the $10,000 SALT cap. If you take the federal standard deduction, none of this affects you. You get the full Arizona credit with no federal complication.
Records to Keep
Get a written receipt from every QCO you donate to. It should include the organization’s name, the donation amount, the date, and a statement about whether you received any goods or services in return.7Internal Revenue Service. Charitable Contributions – Written Acknowledgments Most QCOs send one automatically. If yours doesn’t, ask before year-end.
Hold onto the receipts, your completed Form 321, and the QCO list PDF you used to verify the organization. The IRS generally requires three years of record retention from the date you filed, but with a five-year carry-forward you could theoretically need records seven or eight years back. Keep them until three years after you file the return that finally uses up the credit.8Internal Revenue Service.
