How it Works for Businesses

  • C-Corporations, S-Corporations, and Insurance Companies that pay Premium Taxes may participate in the Corporate Tuition Tax Credit Program.  LLC entities that are taxed as S-Corporations are also eligible.
  • Participating businesses receive a dollar-for-dollar tax credit against their Arizona Corporate Tax Liability.
  • Business contacts AZTO to donate and completes the AZTO Corporate Brochure.
  • For fiscal year 2024-2025, the Corporate Credit Aggregate Cap is $166M. The Arizona Department of Revenue (ADOR) must pre-approve each corporate donation request to monitor the annual aggregate cap.
  • ADOR opens the approval process for fiscal year 2024-2025 donations on July 1st, 2024.  Interested businesses should contact AZTO prior to June 30th for this opening approval cycle.
  • Corporate donations must be at least $5,000. There is no limit to the donation maximum other than it must be approved by the ADOR and under the annual fiscal year aggregate cap.
  • Corporate donor may recommend a specific participating school but not individual students.  Eligible students must meet a state defined low income threshold.
  • AZTO submits donation applications to the ADOR for approval as directed by the state.
  • ADOR has 20 days to approve or deny the corporate donation request based on the annual cap limit.  If the aggregate cap is met, a Waitlist based on the order of submitted applications is created by the ADOR.
  • ADOR discloses the approval status of the donation application request to AZTO.
  • AZTO notifies the business of their approval status. If approved, the business then has 20 days to make the credit donation to AZTO.  If the donation is not made within the 20-day period, the ADOR approval is voided.
  • If the ADOR annual aggregate cap is not met in July, additional approval cycles will open based on the credit available under the cap.  AZTO will continue to accept Corporate Donation Form Requests until the annual cap is met. For the last few years, the aggregate cap has not been met in July.
  • AZTO issues a receipt to the corporate donor. The receipt is then used by the business to claim the corporate credit.
  • Unlike the individual credit, with the corporate credit, the giving deadline is December 31st for the credit to claimed in that tax year.
  • Any unused corporate donation credit may be carried over up to five additional years.
  • ADOR Form 335 is used in claiming the credit.
  • In 2006, Arizona implemented the Low-Income Corporate Tax Credit. (ARS 43-1183 & 43-1089.04)  For more information, see ADOR website.
