Massachusetts rd tax credit for startups offers a 10% credit on incremental qualified research expenses (QREs) plus 15% for basic research payments. What are the requirements for Massachusetts R&D tax credits? Activities must satisfy a four-part test (permitted purpose, technological in nature, elimination of uncertainty, process of experimentation) mirroring federal IRC §41.
How can startups claim Massachusetts R&D credits? Document employee wages, supplies, and 65% of contract research costs tied to in‑state research. Firms like Accountalent provide AI‑enabled R&D studies with audit‑ready documentation.
Massachusetts R&D tax credits are non‑refundable (except for certified life sciences companies) and can offset corporate excise tax. Startups developing software, biotech, hardware, or new processes can claim credits on qualified research conducted physically in Massachusetts. Proper documentation is essential to survive audit.
Understanding Massachusetts Research Credit: A Complete Overview
Massachusetts rd tax credit for startups is one of the most valuable state‑level innovation incentives in the nation. Operated under M.G.L. c. 63, § 38M and detailed in 830 CMR 63.38M.1, the credit rewards businesses for increasing their research spending within the Commonwealth.
Unlike a deduction, this is a dollar‑for‑dollar reduction in your corporate excise tax liability. For life sciences companies certified by the Massachusetts Life Sciences Center (MLSC), a portion of the credit may even be refundable, putting cash directly back into your business.
Why This Credit Matters for Massachusetts Startups
Massachusetts is a global leader in technology, biotech, and clean energy innovation. Yet this high‑opportunity environment comes with high operating costs.
The state’s research credit is designed to lower the after‑tax cost of R&D, encouraging companies to keep their research operations and jobs in Massachusetts. Many early‑stage startups are unaware of the following key benefits:
- 10% credit on incremental Massachusetts Qualified Research Expenses (QREs) over a base amount
- 15% credit for basic research payments made to universities and scientific nonprofits
- Sales tax exemption on R&D equipment and supplies via Form ST‑12
- 15‑year carryforward for unused credits (indefinite for credits limited by the 75% excise cap)
- Up to $500,000 in refundable credits for life sciences companies through the MLSC Tax Incentive Program
A qualified Massachusetts startup accountant can help you identify eligible research, document expenses correctly, and claim both the current‑year credit and refund opportunities.

Who Qualifies for the Massachusetts R&D Credit?
Eligibility for the Massachusetts research credit rests on two pillars: entity type and the nature of the research.
Eligible Entities
| Entity Type | Can Claim the Credit? | Notes |
|---|---|---|
| C‑Corporation | Yes | Can claim both the regular and basic research credit |
| S‑Corporation | Yes | Limited to entity‑level use; cannot pass through to shareholders |
| LLCs / Partnerships | No | Cannot claim directly; partners/members may claim via their own excise |
| Flow‑through entities (certain cases) | Yes | Owners may take credit on their personal excise return under M.G.L. c. 62 |
The credit is non‑refundable for most businesses, meaning it can only reduce tax liability. However, certified life sciences companies may elect to receive a refund for a portion of the credit through the MLSC Tax Incentive Program.
The Four‑Part Test
Massachusetts follows the federal definition of “qualified research” under IRC § 41. To be eligible, your activities must satisfy all four parts of this test:
- Permitted Purpose – Research must be undertaken to develop or improve a product, process, computer software, or invention (including new functionality for existing products).
- Technological in Nature – The research must rely on principles of physical or biological sciences, engineering, or computer science. Market research, social sciences, and arts are excluded.
- Elimination of Uncertainty – Your team must have faced technical uncertainty at the outset about the capability, method, or design of the research.
- Process of Experimentation – You must have engaged in a systematic process—such as modeling, simulation, prototyping, or trial and error—to resolve that uncertainty.
Design work, testing, and debugging can count, but only while technical uncertainty exists. Routine maintenance and post‑commercialization activities generally do not qualify.
For a detailed list of common R&D documentation mistakes that can jeopardize your audit, see Beyond QuickBooks: Modern Bookkeeping for Massachusetts Startups.
Qualified Research Expenses (QREs): What Expenses Count
Once you confirm that your research activities meet the four‑part test, you must identify the specific expenses that can be included in the credit calculation. These are known as Qualified Research Expenses (QREs) and are divided into two categories:
| QRE Category | Included Costs | Special Rules |
|---|---|---|
| In‑House Research | Wages of employees performing, directly supervising, or directly supporting qualified research | Must be Massachusetts‑sourced; includes bonuses and some payroll taxes |
| Supplies | Tangible property (except land or depreciable assets) used and consumed in research | Examples: raw materials for prototypes, chemicals, software testing licenses |
| Contract Research (65% rule) | Payments to third parties for research performed on your behalf | You must retain substantial rights to the results; the third party must perform the research within Massachusetts |
Uncertainty about which supplies count? Unused materials that are resold or stored for future projects may be excluded. For software startups, cloud computing costs (e.g., AWS, Azure) used exclusively for testing and experimentation may qualify, but only if they are consumed in the research process and not used for ongoing operations.
Prudent Practice: Document in Real Time
The Massachusetts Department of Revenue (DOR) imposes contemporaneous documentation requirements. That means you should keep time logs, design documents, test results, and supply invoices as the research happens. Retroactive reconstruction is far less defensible in an audit.
For a deeper dive into calculating and allocating QREs, especially for multi‑state projects, read Extend Your Runway: Tax Planning Strategies for Boston Tech Startups.
Calculating the Massachusetts R&D Tax Credit
Massachusetts offers two calculation methods:
- Regular Method – Credit = 10% × (current‑year QREs – base amount) + 15% × basic research payments
- The “base amount” is generally computed using a fixed‑base percentage of average gross receipts over four prior years.
- Basic research payments are cash payments to qualified educational institutions for fundamental research.
- Alternative Simplified Credit (ASC) – For tax years beginning on or after January 1, 2021, the credit equals 10% of the excess of current‑year QREs over 50% of the average QREs for the three preceding taxable years. If the corporation had no QREs in any of those three years, the credit is simply 5% of current‑year QREs.
| Method | Credit Rate | Base Calculation | Best For |
|---|---|---|---|
| Regular | 10% + 15% | Historical gross receipts and fixed‑base percentage | Companies with stable growth and a long history |
| ASC | 10% (or 5% for start‑ups) | 50% of prior 3‑year average QREs | Startups or companies with fluctuating QREs |
Utilization Cap
The credit is non‑refundable (except for life sciences), and it cannot offset more than:
- 100% of the first $25,000 of corporate excise due
- 75% of any remaining excise after the first $25,000
- The credit cannot reduce your tax below the statutory minimum excise, which is currently $456.
Unused credits can be carried forward for 15 years, and credits disallowed solely because of the 75% cap may be carried forward indefinitely.
Example: If your corporate excise due is $100,000, the maximum credit you can claim in that year is $25,000 + 75% × $75,000 = $25,000 + $56,250 = $81,250. The remaining $18,750 would carry forward.
Federal Coordination
Massachusetts is decoupled from some federal methods. You must compute your Massachusetts QREs and base amount using Massachusetts‑only gross receipts and expenses unless you make a binding election to use your federal apportionment. The state generally follows the federal definitions of QREs and the four‑part test from IRC § 41, but the base calculations can differ.
For a full comparison of how the Massachusetts and federal credits work together, consult your Massachusetts startup accountant.
Massachusetts Life Sciences Tax Incentive Program
Recognizing the importance of biotechnology, Massachusetts provides additional, refundable incentives through the Massachusetts Life Sciences Center (MLSC).
10% Life Sciences Credit (M.G.L. c. 63, § 38W)
Certified life sciences companies can claim a 10% credit on qualified research expenses. Unlike the standard § 38M credit, §38W:
- Allows legally mandated clinical trial expenses incurred both inside and outside Massachusetts
- Provides a 15‑year carryforward for unused amounts
- Enables a refundable claim under the MLSC Tax Incentive Program (see below)
MLSC Tax Incentive Program
The MLSC awards up to $40 million annually in tax incentives to life sciences companies that commit to creating net new jobs in Massachusetts. For 2026, the application period runs from January 12, 2026 to March 31, 2026, at 2 p.m. EST.
Key eligibility requirements include:
- Minimum of 10 permanent Massachusetts full‑time equivalent (FTE) employees as of December 31, 2025 (or 5 FTEs for companies located in Gateway Municipalities or specific counties)
- Commit to hiring 5–10 net new full‑time positions in 2026 and retain them through 2028
- Registered to do business in Massachusetts and current with all state tax and employment filings
Successful applicants receive a refundable tax credit that can provide cash in hand, not just a reduction in liability.
The MLSC program has decertification provisions. If a company fails to meet its hiring commitments, it must return the tax incentives to the Massachusetts Department of Revenue.
Excelsior Program R&D Credit
For general startup companies (not necessarily life sciences), participation in the Massachusetts Excelsior Jobs Program can yield a credit equal to 50% of the federal R&D tax credit for expenditures in Massachusetts. Excelsior credits are refundable. This program is administered through the Massachusetts Office of Business Development.
For step‑by‑step guidance on applying to both the MLSC and Excelsior programs, see Fractional CFO for Startups: Financial Leadership in Massachusetts.
Sales and Use Tax Exemption for R&D
One of the most powerful side benefits of being an R&D corporation in Massachusetts is the sales and use tax exemption on tangible personal property used directly and exclusively in research and development. The exemption is codified in M.G.L. c. 64H, §§ 6(r) and (s) and explained in 830 CMR 64H.6.4.
What Purchases Qualify?
- Materials consumed in R&D
- Fuel used exclusively for research
- Tools and machinery used directly in R&D
- Replacement parts for research equipment
- Prewritten computer software when used in research (under certain conditions)
To take advantage of the exemption, you must:
- Complete Massachusetts DOR Form ST‑12 (Exempt Use Certificate).
- Present the certificate to your vendor at the time of purchase.
- Ensure that your principal activity in Massachusetts is R&D and that you meet either the receipts test (more than two‑thirds of gross revenue from R&D) or the expenditures test (more than two‑thirds of Massachusetts expenditures allocated to R&D).
Even brand‑new startups can qualify for the exemption if they can make a reasonable forecast of their first‑year activities. If you paid sales tax on qualifying purchases in prior years, you may be able to file for a refund.
For a detailed requalification guide and to download Form ST‑12, visit the Massachusetts Department of Revenue’s sales tax page.
Form 6765 and Massachusetts Reporting
For your Massachusetts corporate excise return, you will need to file Schedule RC – Research Credit. The credit calculation is based on the QREs and base amounts you report on your federal Form 6765, but with Massachusetts‑only adjustments.
Important: Massachusetts does not automatically conform to all changes in federal Form 6765. You must maintain separate workpapers for Massachusetts QREs and gross receipts unless you make a binding election to use your federal apportionment. The election must be made on an original, timely filed return and is generally binding for three years.
If you are claiming a refundable credit through the MLSC program, additional schedules and MLSC certification letters are required.
How R&D Credits Intersect with BOI Filing and Compliance
The information you collect to claim R&D credits—especially beneficial ownership details—can also help you satisfy BOI filing obligations under the Corporate Transparency Act. The Massachusetts R&D credit rules require a clear beneficial ownership chain for pass‑through entities, which can be repurposed for your FinCEN BOI report.
If your startup is newly formed in 2026, you must file your BOI report within 30 days of receiving confirmation from the Massachusetts Secretary of the Commonwealth that your company was lawfully formed. Penalties for noncompliance can reach $591 per day. For a detailed walkthrough, see BOI Filing in MA: 2026 Compliance for New Businesses.
Working with an accountant who understands both R&D credit documentation and BOI filing ensures that the same set of ownership and activity records serves multiple compliance purposes.

Frequently Asked Questions (FAQs)
1. What is the Massachusetts R&D tax credit rate for startups?
The standard credit is 10% of incremental qualified research expenses over a base amount, plus 15% of basic research payments. The Alternative Simplified Credit (ASC) uses 10% of current‑year QREs above 50% of the prior three‑year average.
2. Can a pre‑revenue startup claim the Massachusetts R&D credit?
Yes, provided the startup has a corporate excise tax liability. Many early‑stage startups do not owe excise tax, in which case they cannot claim the non‑refundable credit. However, they may qualify for the MLSC refundable credits (life sciences) or the payroll tax offset under the federal R&D credit.
3. Does software development qualify for the Massachusetts R&D credit?
Yes. Software development that involves technical uncertainty, experimentation, and the creation of new or improved functionality counts as qualified research, provided the activities occur in Massachusetts.
4. What is the 15‑year carryforward rule?
Any unused Massachusetts research credit can be carried forward for 15 taxable years following the year the credit was generated. Credits that exceed the 75% utilization cap may be carried forward indefinitely.
5. How do I calculate my Massachusetts “base amount”?
The base amount is generally computed as a fixed‑base percentage (determined over a specified period) multiplied by the company’s average gross receipts for the four preceding tax years, with certain adjustments. The ASC method uses a simpler 50% of the prior three‑year average QREs.
6. What expenses cannot be included in QREs?
Routine data collection, market research, quality control testing, software development after technical uncertainty is resolved, foreign research activities, and general administrative overhead do not qualify.
7. How do I know if my principal activity is R&D for sales tax purposes?
You must have a clear majority of Massachusetts‑based employees engaged in R&D activities in Massachusetts. That majority is measured relative to other Massachusetts activities, not to out‑of‑state activities.
8. What is the deadline for applying for the MLSC Tax Incentive Program in 2026?
The application period runs from January 12, 2026 to March 31, 2026, at 2 p.m. EST. Applications are submitted online through the MLSC portal.
9. Is the Massachusetts R&D credit refundable?
For most companies, no. The credit is non‑refundable, meaning it can only reduce your corporate excise tax liability to $456. However, certified life sciences companies may receive refundable credits through the MLSC Tax Incentive Program, and Excelsior Jobs Program participants may also receive refundable credits.
10. How does the 75% excise limitation work?
You cannot use the research credit to offset more than:
- 100% of the first $25,000 of corporate excise due
- 75% of any excise due in excess of $25,000
The credit cannot reduce your tax below the $456 minimum.
11. How do I claim the Massachusetts R&D credit on my tax return?
You must file Schedule RC with your Massachusetts Form 355 or Form 63‑20P. The credit calculation is based on your federal Form 6765 adjusted for Massachusetts‑only QREs.
12. Are contract research expenses eligible if performed outside Massachusetts?
No. The contract research must be performed within Massachusetts to qualify for the Massachusetts credit. The 65% rule for contract research still applies.
13. What is the Massachusetts alternative simplified credit (ASC) phase‑in?
For tax years beginning on or after January 1, 2021, the ASC is a full 10% credit. During the phase‑in period (2015–2020), the rate increased gradually from 5% to 7.5% to 10%. So the current rate is stable at 10%.
14. Can I amend prior‑year returns to claim missed Massachusetts R&D credits?
Yes. You can file an amended Massachusetts corporate excise return to claim credits for up to three prior tax years. However, you must have contemporaneous documentation for those years.
15. Does Massachusetts require me to reduce my R&D expense deduction by the amount of the credit claimed?
Yes. The Massachusetts deduction allowed for any research expenses generating the credit must be reduced by the amount of the credit.
16. What is the difference between the Massachusetts Research Credit and the MLSC Life Sciences Credit?
The standard research credit (M.G.L. c. 63, § 38M) applies to all qualified research. The life sciences credit (M.G.L. c. 63, § 38W) is specifically for MLSC‑certified life sciences companies and allows clinical trial expenses incurred outside Massachusetts. §38W also has a more favorable 15‑year carryforward.
17. How do I verify my accountant’s qualifications for R&D credit work?
Check the Massachusetts Board of Public Accountancy license verification. Additional resources include the Massachusetts Society of CPAs (MassCPAs).
18. What is the Massachusetts sales tax exemption form number for R&D purchases?
You must use Form ST‑12 (Exempt Use Certificate). The form must be presented to your vendor at the time of purchase. You can download it from the Massachusetts DOR website.
19. Can I claim both the federal and Massachusetts R&D credits for the same expense?
Yes, but you must adjust your federal deduction. The Massachusetts credit is computed independently using Massachusetts‑only QREs. There is no double‑counting, but you should coordinate with your tax advisor to optimize both credits.
20. Does Accountalent offer a free consultation for Massachusetts R&D credits?
Yes. Accountalent provides a free initial consultation to evaluate your eligible research activities and estimate your potential credits. Visit accountalent.com to schedule.
