Arizona Form 323 – Credit for Contributions to Public Schools
Last reviewed: 2025-11-16
Use the Arizona Tax Form Calculator Form 323: Arizona Credit for Contributions to Public Schools as a stand alone tax form calculator to quickly calculate specific amounts for your 2026 Arizona state tax return. Alternatively, you can use one of our Combined Federal and State Tax Estimators to quickly calculate your salary, tax, and take-home pay.
Arizona Form 323 is used by individuals who make voluntary contributions to Arizona public schools to support extracurricular activities, character education, and certain career and technical programs. Arizona offers one of the most widely used credits in the state tax system, allowing taxpayers to claim a dollar-for-dollar reduction in tax for qualifying public school contributions. Taxpayers who make eligible donations can take the credit regardless of whether they itemize deductions.
This form captures both the current-year contribution and any unused carryforward amounts from the previous five years. The credit is limited by filing status and cannot exceed statutory annual caps, but unused amounts can be carried forward for up to five tax years. The credit may be claimed even if the taxpayer has already taken other education-related credits under Arizona law.
How the Arizona Public School Tax Credit Works
Form 323 is structured to calculate the allowable credit and any remaining carryforward in a straightforward three-step flow. To complete the process, taxpayers must:
- Enter current year contributions made directly to an Arizona public school for eligible purposes. Cash and nonrefundable payments qualify.
- Add any carryforward from the prior year. Arizona allows unused credit amounts to roll forward for up to five tax years.
- Apply the statutory maximum based on filing status. The limit is different for single filers and married couples filing jointly.
The calculator automatically tests your combined contributions against the filing status limit and computes the allowable amount, the credit permitted this year, and the remaining contribution balance that may be carried forward. Only contributions made directly to qualifying public schools count—payments to PTOs, third-party organizations or booster clubs generally do not qualify.
| Filing Status | ||
| 1 | Current year contributions to Arizona public schools | |
| 2 | Excess contributions carried forward from prior years | |
| 3 | Total available contributions: Add lines 1 and 2 | |
| 4 | Maximum credit allowed for filing status | |
| 5 | Credit allowed this year: Lesser of line 3 or line 4 | |
| 6 | Carryforward to next year: Line 3 minus line 5 (if > 0) | |
Eligibility and Qualifying Contributions
Contributions may support a variety of programs offered through Arizona public schools. Qualifying uses typically include:
- Extracurricular activities or student enrichment programs
- Character education programs
- Career and technical education fees
- Clubs, arts, music, and athletics
- Field trips tied to curriculum requirements
The contribution must be voluntary, nonrefundable and paid directly to the school. Taxpayers must retain a receipt from the school documenting the contribution amount and program designation. The credit is available whether or not you itemize deductions and is separate from the credits for private school tuition organizations (Forms 322 and 323).

Frequently Asked Questions
What is Arizona Form 140EZ and who is eligible to file it?
Arizona Form 140EZ is the simplest of all Arizona resident income tax returns. It is specifically designed for full-year residents with very basic tax situations—typically wage earners or retirees whose income and deductions require no adjustments or additional schedules. Form 140EZ supports only a limited range of income types and does not allow itemized deductions, business income, capital gains adjustments, Arizona additions, or complex credits. Taxpayers eligible for Form 140EZ must meet strict criteria, including filing as Single or Married Filing Jointly, having only basic income sources, and claiming the standard deduction. It is ideal for those who want a quick and streamlined method to file their Arizona taxes without navigating the complexity of longer forms.
How do credits interact with amended returns filed using Form 140X?
Credits must be recalculated as if the return were being filed for the first time. If the amendment increases income or changes filing status, previously claimed credits may decrease. If the amendment adds a missed credit—such as those calculated on Forms 321, 322, 323 or 348—taxpayers should attach the full credit form to the amended return. Unused credits with carryforward provisions may need adjustment across multiple years.
Can Form 131 be used when amending a deceased taxpayer’s prior-year return?
Yes. If a deceased taxpayer is owed money from an amended return—such as correcting income, claiming a missed credit or adjusting withholding—the claimant must resubmit Form 131 with the amended return. The Arizona Department of Revenue requires the form each time a refund is issued, even if one was previously accepted for another year. Guidance on pairing Form 131 with amended returns can be reviewed alongside the amended return calculator at Arizona Form 140X.
Does Form 140EZ allow itemized deductions or only the standard deduction?
Form 140EZ only permits the standard deduction. Itemized deductions—including mortgage interest, medical expenses, property taxes, charitable contributions, and other Schedule A items—cannot be claimed on this form. The Form 140EZ standard deduction is predefined based on filing status and does not allow for additional increases such as charitable deduction boosts available on other forms. Taxpayers who wish to itemize must instead file Form 140.
What are the annual credit limits for QFCO contributions?
Arizona sets distinct limits for Single/HOH/MFS filers and for Married Filing Jointly. Taxpayers may claim only up to the allowable limit. Any contributions above that limit cannot be refunded but may be carried forward for up to five years. These limits are separate from those used for QCO contributions (Form 321), meaning taxpayers can claim both credits in the same tax year.
