Maryland R&D Tax Credits

Find out if you qualify for R&D tax credits in Maryland and recharge your business.

​​​​​​​​Businesses that have qualified R&D expenditures in Maryland may qualify for two separate income tax credits, the Basic R&D Tax Credit and the Growth R&D Tax Credit. To qualify for the Basic and/or Growth R&D tax credit, a business must submit an application NO LATER THAN November 15th of the calendar year following the tax year in which the expenses were incurred.

In addition, the credits are refundable for eligible small businesses that submit documentation showing they had net book value assets at the beginning or end of the tax year of less than $5 million (as reported on the balance sheet).

Applicants must apply using an online system. Maryland has a yearly cap on the amount of R&D credits available to applicants. Maryland's Commerce Department will prorate the R&D credits pro rata in the following circumstances:

  • the total amount of Basic Credits applied for exceeds $5.5 million; or
  • the total amount of Growth Credits applied for exceeds $6.5 million.

Each taxpayer (applicant) will receive an R&D credit Certification Letter with the approved credit amount by February 15th of the following year.

Because application dates follow the filing date for taxes, after receiving the Certification Letter, the taxpayer can file an amended tax return for the certified year, or it may claim the credit on any income tax return filed in any of the subsequent 7 tax years. The business must attach a copy of the Certification Letter to its Maryland income tax return.

The tax credit remains in effect until June 30, 2022, subject to extension by the Maryland General Assembly.
