Short answer. Maryland's research credit is 10 percent of eligible research spending above a Maryland base, capped at $250,000 per applicant per year. It is refundable for a small business with under $5 million in assets, the program is application-based with a November 15 deadline, and it sunsets January 31, 2031.

10 percent, then the caps
The rate is simple; the caps decide the real number.
The credit is 10 percent of eligible research and development expenses incurred in Maryland above the Maryland Base Amount, which parallels the federal Section 41 base but is limited to Maryland expenses. Above that 10 percent, three caps apply. The program pays out at most $12 million a year across all applicants, with $3.5 million reserved for small businesses, and no single applicant can receive more than $250,000 in a year.
If applications exceed the pool, every award is pro-rated. That makes your computed credit a ceiling, not a guarantee.
The small-business refund
Maryland's best feature for an early-stage company is the cash refund.
A small business, meaning a for-profit entity with net book value of assets under $5 million, can have the credit refunded to the extent it exceeds Maryland income tax. The full certified amount is refundable, subject to the $250,000 per-applicant cap, rather than a percentage of it, which is more favorable than most state refund programs. For a non-small business the credit is not refundable, and excess carries forward seven years.
An application, not a self-claim
Maryland's credit is earned by applying, on a fixed calendar.
This is an application-based program. By November 15, the business files an application with the Maryland Department of Commerce that includes the eligible expense computation, the base amount, and supporting documentation. The certified credit is then claimed on the Maryland return for the year it relates to.
The credit applies to tax years through January 31, 2031, subject to extension by the General Assembly. Maryland has renewed it before, so the workpaper plans to the current sunset while a further extension stays possible.
