Alaska R&D Tax Credit Summary

Although Alaska does not provide a Alaska state-specific R&D Tax credit based on qualified research expenses that mirror the Federal Research Tax credit, Alaska provides a state tax credit equal to eighteen percent (18%) of a company's federal-based credits, which includes the research and development tax credit. See 15 AAC 20.145. Credits adopted by reference.


Alaska also offer several other credits (see link).  See also IRC § 38 for a complete list of federal-based credits eligible for the state credit.

Under IRC § 41, where a credit allowed under the Internal Revenue Code is also allowed in computing Alaska income tax, it is limited to 18% for corporations of the amount of credit determined for federal income tax purposes which is attributable to Alaska. This limitation does not apply to a special industrial incentive tax credit under AS 43.20.042

  • For purposes of calculating the federal tax payable on personal holding companies, the rate is 12.6%

  • For purposes of calculating the accumulated earnings tax, the rate is 4.95% of the first $100,000 of accumulated taxable income and 6.93% of accumulated taxable income in excess of $100,000

  • Qualified activities need not be conducted in Alaska to qualify, but must be conducted within the United States

  • The definition of qualified research expenses is the same as under IRC § 41.

  • Federal-based credits may offset Alaska alternative minimum tax (AMT) only after Alaska incentive credits are applied.
