Iowa Research and Development Tax Credit Summary

The Iowa R&D Tax Credit is similar to the federal R&D Tax Credit version in that it allows the credit to be calculated using either the Regular or Alternative Simplified Credit Method. Additionally, the definition of qualifying research is the same as defined in IRC Sec. 41. Below are some of the differences between the federal R&D Tax Credit and Iowa R&D Tax Credit.

  • The Iowa R&D Tax Credit is fully refundable after a company's tax liabilities are met.
  • Only expenses incurred in Iowa can be captured towards the Iowa research activities credit.
  • The Iowa regular credit is 6.5% of the lower of qualifying research expenditures that exceed a base amount or 50% of qualifying research expenditures.
  • Iowa's Alternative Simplified Credit is 4.55% of expenditures occurred in Iowa for the past three years.
  • Companies that receive awards from the Iowa Economic Development Authority under the Enterprise Zone Program or the High Quality Jobs Program can calculate a Supplemental Research Activities Credit. The Supplemental Credit is an additional 10% of a company's qualifying incremental research expense for gross revenues less than $20 million and 3% for a company with gross revenues over $20 million.
  • The Supplemental Research Activities Credit must be calculated using the same method that the Research Activities Tax credit was calculated.
