Arizona Charitable Tax Credits: Redirect Your State Tax Dollars (QCO, QFCO, Public School, STO)

If you live in Arizona and give to charity (or support a local public school), you may be able to redirect your state tax dollars—not just deduct them.
Arizona offers nonrefundable income tax credits for Qualified Charitable Organizations (QCO), Qualified Foster Care Charitable Organizations (QFCO), the Public School Tax Credit, and Private School Tuition Organizations (STO). For many households, this is one of the most overlooked tax planning strategies available.

Practical Breakdown for Arizona Taxpayers

Qualified Charitable Organization (QCO) Tax Credit

Statute: A.R.S. § 43-1088
Forms: Arizona Form 321 (and Form 301 summary)

The QCO credit allows a dollar-for-dollar reduction of Arizona income tax for cash donations made to an ADOR-certified QCO.

2025 limits (for 2025 returns)

  • $495 (Single/HOH/MFS)
  • $987 (Married Filing Jointly)

2026 limits

  • $506 (Single/HOH/MFS)
  • $1,009 (Married Filing Jointly)

Not all charities qualify. An organization must be state-certified as a QCO—not just a 501(c)(3). For 2025 you can find the list of charitable organizations by clicking here. Certification requirements include:

  • Providing basic needs services
  • Serving qualifying low-income or at-risk populations
  • Meeting specific budget allocation requirements

(See A.R.S. § 43-1088 and ADOR QCO certification guidance.)

Qualified Foster Care Organization (QFCO) Credit

Statute: A.R.S. § 43-1088
Forms: Arizona Form 352 (plus Form 301)

This is a separate credit within the same statute for foster-care-focused organizations.

QFCOs must meet additional statutory requirements, including serving at least 200 foster-related individuals annually.

  • For cash contributions only
  • To ADOR-certified organizations (2025 Organizations)
  • Subject to statutory limits

Arizona Public School Tax Credit (Form 322)

Statute: A.R.S. § 43-1089.01
Forms: Arizona Form 322
(instructions: Form 322 Instructions)

Arizona allows a nonrefundable, dollar-for-dollar tax credit for eligible cash contributions or fees paid directly to an Arizona public school for qualifying extracurricular activities, programs, or purposes.

2025 limits

  • $200 (Single/HOH/MFS)
  • $400 (Married Filing Jointly)

2026 limits

Key rules to know:

  • Must be paid directly to a public school for qualifying activities/programs
  • Credit-eligible contributions made by April 15 may be applied to either the current or prior tax year (see Form 322 instructions)

Arizona Private School Tuition Tax Credits (STO Credits)

Why Work With an Arizona Tax Advisor or an Arizona Financial Planner?

These credits can help donate with intention—but they must be coordinated with:

  • Federal deduction limitations
  • IRA distribution strategy
  • State tax liability projections
  • Carryforward planning
  • Filing deadlines and documentation

If structured properly, Arizona charitable tax credits can significantly reduce state income tax while supporting causes you care about.

If structured improperly, you could lose eligibility or trigger unintended federal tax consequences.
