Corporate Tax Credit

In 2006 and then in 2008, the Arizona State Legislature passed into law the Corporate Income Tax Credit and then the Disabled/Displaced Corporate Income Tax Credit (A.R.S. §20-224.06 and § 43-1183), which allows a corporation to contribute to a qualified STO (School Tuition Organization) and receive a dollar-for-dollar Tax Credit up to the total amount of their tax liabilities and may qualify to also claim that amount on their federal taxes as a donation. STO4KIDZ in turn awards a minimum of ninety percent of contribution in form of scholarship to eligible students with verified financial needs in the same tax year.

The 2022 FY Statewide Corporate Tax Credits are available in 2 categories:

  • Low-Income Cap: $142,113,727    
  • Disabled/Displaced Cap: $6,000,000


To proceed, please refer to the “Corporate Tax Allocation Process and Timeline” button listed below.

  • Can allocate up to 100% of your corporate state income tax liabilities towards eduction
  • Receive a dollar-for-dollar tax credit
  • Provide scholarships for eligible K-12 Arizona private school students
  • STO4KIDZ, in turn, awards a minimum of 90% of every dollar in scholarships to eligible AZ private school students within the same school calendar year

  • C-Corporations
  • S-Corporations & LLCs that file as an S-Corp
  • Insurance Companies that pay premium taxes in Arizona

C-Corporations can allocate up to 100% of their state income tax liabilities for the given tax year as long as it does not exceed the statewide cap for the year. Credit can be carried forward for up to 5 years.

S-Corporations, (as defined in section 1361 of the Internal Revenue Code) can either claim the credit against income taxes at the corporate level (income tax reported on an Arizona 120S corporate income tax return) or it may make an irrevocable election to pass the credit through to its individual shareholders.  The S-Corp must make a minimum aggregate contribution of $5,000 within their taxable year in order to pass the credit through to its shareholders and may allocate up to 100% of their state income tax liability for the given tax year, receive a dollar-for-dollar tax credit; then pass the credit on to its shareholders proportionately. If a corporation allocates more than their tax liability, it can be carried forward for up to 5 years. The contribution must be made by the S-corp, not a shareholder, in order to be eligible for the corporate tax credit. Each individual shareholder may claim only a pro-rata share of the credit based on the individual’s ownership interest in the S-corp. (A.R.S. § 43-1089.04).

LLCs that are taxed as S-corporations for federal and state purposes are eligible to contribute for tax credit.

Insurance companies that pay Arizona state tax liability on their premium income can allocate up to 100% of their premium tax liabilities.

(Use tax form 335 to claim your credit)

No. Corporations can only claim their contribution in the tax year in which the contribution is made (plus, five years for carry forward purposes). The law allows your corporation to allocate your tax liability to a School Tuition Organization (STO) such as STO4KIDZ, designating a private school, not a specific student. However, if there are not enough eligible students at your designated school, the money will be awarded among eligible students attending other qualifying private schools in Arizona.
