Are R&D Tax Credits Available in Delaware?

The state of Delaware provides the Research and Development (R&D) Tax Credit very similar to the federal version including the definition of qualifying research. Below are some of the differences between the federal and Pennsylvania research credits:

  • There are two ways to calculate credit. First, use 10% of the excess of the taxpayer's total Delaware qualified R&D expenses for the taxable year over the taxpayer's Delaware base amount. Second, 50% of Delaware’s apportioned share of the credit if using the federal Alternative Simplified method.
  • For taxpayers with average gross receipts under $20 million, the credit rate is adjusted to 10%, and using the Alternative Simplified method allows 100% of Delaware’s apportioned share of the federal credit.
  • Qualified research must take place in Delaware.
  • Excess Delaware research credits can be carried forward for fifteen years and are refundable.
  • Qualified taxpayers must submit an application to the Division of Revenue by September 15 for research expenses incurred in the taxable year that ended in the prior calendar year.
