Maryland: 10 percent, $250,000 cap, and a refund for small SaaS.

Rate	10% over the Maryland base
Refundable	Yes (small business)
Note	$250,000 per-applicant cap; sunsets Jan 31, 2031

The credit is 10 percent of eligible R&D expenses incurred in Maryland in excess of the Maryland Base Amount. The base amount calculation parallels the federal §41 base computation but is restricted to Maryland-attributable expenses. The Maryland Department of Commerce follows the federal IRC §41(b) definition of qualified research and qualified research expenses.

Three caps shape the actual award:

• Total program cap: $12 million per year. Across all applicants.
• Small business set-aside: $3.5 million. Reserved within the $12 million for businesses with net book value of assets totaling less than $5 million.
• Per-applicant cap: $250,000 per year. No single business can receive a credit exceeding this amount in a given year, regardless of computed credit size.

If the total credits applied for exceed the statutory caps, each business's credit is pro-rated. This makes the gross computed credit a ceiling, not a guarantee.

The credit applies to taxable years through January 31, 2031, subject to extension by the Maryland General Assembly. The credit was renewed in prior years, so a further extension is plausible, but the workpaper should plan to the current sunset and not assume extension.

Maryland's distinctive feature for early-stage SaaS is the small business refund. R&D tax credits certified after December 15, 2012 are refundable for small business to the extent that the tax credits exceed the income tax liability.

Small business is defined in the Maryland R&D credit context as a for-profit corporation, LLC, partnership, or sole proprietorship with net book value of assets totaling less than $5 million. This is the same threshold used in Pennsylvania's R&D credit, which simplifies eligibility for a multi-state SaaS company that already evaluates the threshold for PA purposes.

The refund is the amount by which the certified credit exceeds the Maryland income tax liability for the year. The full certified amount is available (subject to the $250,000 per-applicant cap), not a percentage of it, which is more favorable than Pennsylvania's 65 percent refund exchange or Connecticut's 65 percent small business exchange.

For non-small businesses, the credit is not refundable. Excess credit carries forward for 7 tax years.

The Maryland R&D credit is an application-based program, not a self-claimed credit. The sequence is:

• By November 15. The business submits an application to the Maryland Department of Commerce. The application includes computation of eligible R&D expenses, base amount, and computed credit, plus supporting documentation.
• By February 15. The Department of Commerce issues the certification. If applications exceed the caps, certified amounts are pro-rated within the small business and standard pools.
• On the tax return. The certified credit is claimed on the Maryland income tax return for the tax year to which the credit relates. Small business refundable certifications produce a refund where the credit exceeds liability.

Statutory and administrative materials: Maryland Department of Commerce Research and Development Tax Credit Program (program overview and application instructions). Form 500CRW is the waiver request used when a business cannot file electronically and needs to file the credit claim on paper.

R&D Binder produces federal Section 41 documentation from your GitHub commit history. The binder supports your federal Form 6765 and, starting tax year 2026, the mandatory Form 6765 Section G appendix. The same documentation foundation supports Maryland because the Maryland Department of Commerce uses the federal §41(b) definition of qualified research and qualified research expenses.

The Maryland state credit workpaper is a $995 add-on to the standard binder engagement. It produces:

• A Maryland-attributable QRE breakdown (employee, contractor, and supplies expenses tied to research conducted in Maryland, using the same business-component partition as the federal binder).
• Maryland Base Amount computation.
• Computed credit at 10 percent of QRE above the base, with the $250,000 per-applicant cap applied.
• Small business eligibility documentation (net book value of assets under $5 million) so your CPA can confidently apply for the refundable small business pool.
• The full application packet your CPA forwards to the Maryland Department of Commerce by November 15.
• Pro-rata sensitivity table: the certified credit alongside historical pro-rata outcomes so your CPA can advise on realistic realization.
• Filing notes for your CPA: certification timing, refund mechanics, 7-year carryforward window for non-refundable excess.

We do not submit the Department of Commerce application, file the Maryland return, or sign anything for the taxpayer. That stays with your CPA. R&D Binder produces the workpaper; your CPA applies and files.

A worked example. A Bethesda SaaS company with 14 engineers, $3.2M in qualifying wages (federal QRE pool), 8 engineers physically located in Maryland, and $4.2 million in net book value of assets (qualifies as small business for the refundable pool).

• Federal Section 41 credit. Computed on the full $3.2M federal QRE pool through Form 6765, claimed by the CPA. R&D Binder produces the binder, QRE workpaper, and Form 6765 Section G appendix.
• Maryland credit (gross). Computed on the Maryland-attributable portion of QREs. Roughly $1.83M ($3.2M times 8/14 engineer location ratio). With a Maryland Base Amount of approximately $1.0M, the credit base is $830,000. At 10 percent, the gross computed credit is $83,000.
• Per-applicant cap. The $83,000 computed credit is below the $250,000 per-applicant cap, so the cap does not bite. The pro-rata risk applies to the small business pool overall; the workpaper presents a range under different pool subscription scenarios.
• Refund election. With minimal Maryland income tax liability, the small business refundable provision applies. The certified credit (after any pro-rata reduction) is paid as cash to the extent it exceeds liability.
• Total engagement cost. SaaS Standard tier ($4,995, 6 to 25 FTE) plus Maryland state workpaper add-on ($995). Total $5,990.

A larger Maryland SaaS with $4 million of QRE above the base would compute a $400,000 credit but receive $250,000 (the per-applicant cap). The $150,000 above the cap is lost; it does not carry forward. This is a meaningful planning point for high-QRE Maryland companies.

The Maryland Comptroller of Maryland and the Department of Commerce share examination responsibility for the R&D credit. The Department of Commerce reviews substantiation at the certification stage; the Comptroller may examine the claim again as part of a return audit. Both apply substantially the same substantiation expectations as the IRS under federal Section 41: business-component identification, four-part-test rationale, contemporaneous evidence, QRE allocation by employee, contractor, and supplies. Both scrutinize the Maryland in-state performance documentation and the net book value documentation for small business eligibility.

The binder R&D Binder produces is built to that standard from the federal side, and the Maryland workpaper carries employee location attribution and small business net-book-value reconciliation into the same business-component structure.

Our standard scope ends at delivering the binder and the state workpaper. Audit-defense engagement for a Maryland Department of Commerce or Comptroller examination is a separate scope at $250 per hour, scoped per-incident. We do not represent before either agency; that stays with your CPA or your Maryland tax controversy attorney.
