Arizona R&D Tax Credit Summary


Arizona State R&D Tax Credit

A credit provides an additional Arizona nonrefundable income tax credit for qualifying basic research payments made during a taxable year to one or more of the three universities under the jurisdiction of the Arizona Board of Regents: Arizona State University, Northern Arizona University and the University of Arizona. The credit is equal to 10% of the excess, if any, of the “basic research payments” made by a taxpayer in a taxable year over the taxpayer’s “qualified organization base period amount” for the taxable year. The amount of the credit is determined under IRC § 41, except that:

  • qualified research includes only research conducted in Arizona
  • if two or more taxpayers share in the eligible expenses (including partners in a partnership effective December 31, 2000), each taxpayer is eligible to receive a proportionate share of the credit
  • the termination provisions of IRC § 41 do not apply

    Computation of credit for 2011–2022: For tax years 2011 through 2022, the credit is based on the excess, if any, of the qualified research expenses for the taxable year over the base amount as defined in IRC § 41(c), and is computed as follows:

    • if the total is $2.5 million or less, the credit will be 24% of that amount
    • if the total is over $2.5 million, the credit will be $600,000 plus 15% of any amount exceeding $2.5 million
    • Any amount of additional credit that exceeds taxes due is not refundable, but may be carried forward for five consecutive tax years*

    For 2023 and thereafter, the R&D tax credit percentages will be 20% of the first $2.5 million in qualifying expenses plus 11% of the qualifying expenses in excess of $2.5 million.

    Unused credit may be carried forward for 15 years. Taxpayers with qualified research expenses to carry forward from tax years starting before January 1, 2001, may only carry forward 20% of the carry forward expenses.

    Flow-Through Entity

    If two or more taxpayers, including partners in a partnership and shareholders of an S corporation, as defined in section 1361 of the internal revenue code, share in the eligible expenses, each taxpayer is eligible to receive a proportionate share of the credit.


    The ACA has been given the authority to approve refunds under this program up to $5 million in any calendar year. Therefore, refunds are approved by the ACA on a first-come, first-served basis, according to the date and time an application is filed with the ACA. Applications must be based on actual numbers, not estimates. A calendar year taxpayer may file an Application on or after the first business day following the close of the previous calendar year. A fiscal year taxpayer may file an Application on or after the first business day after the end of the fiscal year.

    A company may be eligible for a partial refund of its R&D tax credit if it:

    • Meets the eligibility requirements of A.R.S. §§ 41-1507 and 43-1074.01 or 43-1168 and the company’s current year’s Arizona R&D tax credit exceeds its current year’s tax liability.
    • Submits an application to the ACA and receives a Certification of Qualification prior to filing a tax return with Revenue.
    • Employs less than 150 full-time employees worldwide as of the last day of the taxpayer’s taxable year.
    • Remits a non-refundable processing fee equal to 1% of the company’s tax credit being refunded.
    • Does not exceed the tax year refund limitations under A.R.S. § 41-1507 (E)
    • Complies with employer and business sanctions set forth in A.R.S. § 23-214 (B) and A.R.S. § 35-393.
