The Mechanics of Credit Generation and Sharing: An Analysis of the Massachusetts Research and Development Tax Credit
The “Credit Generated by an Individual Member Corporation” refers to the specific portion of the Massachusetts Research Credit produced by a single legal entity within a combined group based on its discrete qualified research expenses. Under the Commonwealth’s regulatory framework, this designation identifies the primary owner of the credit for the purposes of initial tax application, group sharing priority, and the retention of carryforward balances.
The Massachusetts Research and Development (R&D) Tax Credit, codified under Massachusetts General Laws (M.G.L.) Chapter 63, Section 38M, represents one of the most sophisticated and economically significant incentives within the state’s corporate excise structure.1 At its core, the credit is designed to reward businesses that invest in high-level scientific and technological inquiry within the geographical boundaries of the Commonwealth. While the credit calculation for large enterprises often involves an “aggregated” approach—treating a controlled group of corporations as a single taxpayer to determine the total incentive—the law maintains a rigorous distinction regarding which specific member “generated” the credit.3 This distinction is not merely a matter of bookkeeping; it is a fundamental legal principle that dictates how credits are used to offset excise liability, how they are shared among affiliates in a combined report under M.G.L. c. 63, § 32B, and how they are preserved if a corporation undergoes a structural change or exits a group.2
Statutory Framework and the Adoption of Federal Standards
The Massachusetts Research Credit was established to stimulate innovation by providing a direct offset against the corporate excise for qualified expenses.6 The statute, M.G.L. c. 63, § 38M, largely mirrors the federal research credit available under Internal Revenue Code (IRC) § 41 as it existed on August 12, 1991.3 By tethering the state credit to federal definitions, the Massachusetts Department of Revenue (DOR) provides a level of predictability for taxpayers, allowing them to utilize existing federal compliance data as a baseline for state-level claims.3
However, the Massachusetts credit diverges from the federal model in its strict geographical requirements. To contribute to the generation of a credit by an individual member corporation, the underlying expenses must be “Massachusetts qualified research expenses” (QREs).4 This means the research activity must be conducted physically within Massachusetts. For a multi-state corporation, the process of identifying which entity generated the credit requires a granular analysis of where research personnel are located, where supplies are consumed, and where the research facilities are situated.4
The Four-Part Test in the Massachusetts Context
For an individual member corporation to generate the credit, its activities must satisfy the “four-part test” derived from IRC § 41. The DOR and the courts look for evidence that the research is technological in nature, involves a process of experimentation, is intended to eliminate technical uncertainty, and serves a permitted purpose such as creating a new or improved product or process.7
| Criteria | Narrative Requirement | Massachusetts Specificity |
| Technological in Nature | The research must rely on principles of physical, biological, or computer science. | The expertise must be deployed within Massachusetts facilities.7 |
| Process of Experimentation | Substantially all activities must constitute a process of evaluating alternatives. | Documented experimentation must occur at Massachusetts sites.7 |
| Elimination of Uncertainty | The activity must be intended to discover information to eliminate uncertainty. | Uncertainty must be addressed by Massachusetts-based personnel.7 |
| Permitted Purpose | The goal must be to improve functionality, performance, reliability, or quality. | The resulting intellectual property or product improvement must stem from MA R&D.7 |
The interaction between these federal standards and the Massachusetts nexus requirement forms the basis for “generating” the credit. When an individual corporation incurs a wage expense for a scientist working in a Cambridge lab, that corporation is the legal “generator” of the credit associated with those wages.3
Defining Qualified Research Expenses (QREs)
The generation of the credit is predicated on four primary categories of expenditure. Each category has specific rules for proration when activities cross state lines, which further refines the identity of the generator.4
Wages for Qualified Services
Wages constitute the largest portion of most R&D credit claims. For an individual member corporation to generate a credit through wages, the employee must be engaged in qualified research, direct supervision of research, or direct support of research.4 If an employee spends only a portion of their time on research, or a portion of their time in Massachusetts, the generator must prorate the wages.4
| Employee Activity Location | Treatment for Credit Generation |
| 100% Massachusetts R&D | 100% of wages qualify for generation by the employer.4 |
| Mixed MA and Out-of-State R&D | Prorate based on the ratio of days worked in MA to total days.4 |
| 80% or more on R&D | 100% of wages are treated as QREs (federal “substantially all” rule).4 |
Supplies Used in Research
The cost of supplies used or consumed in the conduct of qualified research in Massachusetts contributes to the credit generation.4 This includes prototypes and testing materials but excludes depreciable property, land, or improvements to real property.4 The individual member corporation that purchases and uses the supplies is the entity that generates the credit.3
Computer Fees and Rental Costs
Amounts paid for the right to use computers for research purposes are eligible, provided the computers are located in Massachusetts.4 This often applies to cloud computing or time-sharing arrangements where the processing power is dedicated to Massachusetts-based research projects.4
Contract Research Expenses
When a corporation pays a third party to perform research on its behalf, 65% of the expense is generally treated as a QRE.4 To generate a Massachusetts credit, the contracted research must be performed at a facility located within the Commonwealth.3
Calculation Methodologies: Traditional vs. Alternative Simplified Method
Massachusetts offers two methods for calculating the credit, each of which results in a “generated” amount for the individual corporation. The choice of method is an election made by the taxpayer and can significantly influence the credit’s value.3
The Traditional Method (M.G.L. c. 63, § 38M(a))
The Traditional Method is an incremental calculation that measures current spending against a historical baseline. The credit generated under this method is the sum of 10% of the excess QREs over a “base amount” and 15% of “basic research payments”.2
The “base amount” is defined as the product of the corporation’s average annual gross receipts for the four taxable years preceding the credit year and a “fixed-base ratio”.2 For Massachusetts purposes, the fixed-base ratio is capped at 16%, and the base amount cannot be less than 50% of the current year’s QREs.2
The Alternative Simplified Method (ASM/ASC)
Recognizing that many modern corporations lack the historical data required for the Traditional Method, Massachusetts adopted the ASM (frequently referred to as the ASC) in 2015.3 The ASM credit is calculated as a percentage of the amount by which current-year Massachusetts QREs exceed 50% of the average Massachusetts QREs for the three preceding years.2
The ASM rate has transitioned as follows:
| Tax Year Period | ASM Credit Rate | Statutory Authority |
| 2015 – 2017 | 5.0% | M.G.L. c. 63, § 38M(b).2 |
| 2018 – 2020 | 7.5% | M.G.L. c. 63, § 38M(b).2 |
| 2021 and forward | 10.0% | M.G.L. c. 63, § 38M(b).2 |
If an individual member corporation did not have QREs in any of the three preceding years, the credit is equal to 5% of the current year’s Massachusetts QREs.2 One critical distinction is that the 15% basic research payment add-on is not available to taxpayers electing the ASM.9
The Concept of the Aggregated Group and the “Single Taxpayer” Rule
In the context of related corporations, the DOR requires that the research credit be calculated on an aggregated basis.3 This rule applies to all corporations that are members of a “controlled group” as defined by IRC § 41(f)(1)(A) or are under common control.4
The purpose of aggregation is to prevent the “shifting” of research expenses between related entities to artificially increase the credit.4 Under the aggregated approach, the entire group is treated as a single taxpayer. The group calculates its total QREs, its total historical base, and its total group credit.3
The Attribution of the “Generated” Credit
Once the aggregated group credit is calculated, it must be attributed back to the individual member corporations. This step is essential because the credit “generated” by each member determines their ability to use and share the incentive.3
The allocation of the group credit is generally performed based on the ratio of the individual member’s QREs to the group’s total QREs.3 For example, if Member A incurred 60% of the group’s QREs, it is credited with generating 60% of the total group research credit.3
Limitations on the Application of Generated Credits
The credit generated by an individual member corporation is not an unlimited offset against the Massachusetts corporate excise. The law imposes significant constraints to ensure a minimum tax contribution from all corporations.12
The $25,000 Threshold and the 75% Rule
The most prominent limitation is the “75% rule” set forth in M.G.L. c. 63, § 38M(d). A corporation may use its research credits to offset 100% of its first $25,000 in corporate excise liability.2 For any excise liability in excess of $25,000, the credit can only be used to offset 75% of that additional amount.9
In an aggregated group, the $25,000 threshold is not provided to each member individually. Instead, the members must share a single $25,000 amount.3 The DOR instructs that the $25,000 threshold be apportioned among the group members based on the ratio of each member’s separately determined excise to the total group excise.3
The Minimum Excise Floor
A secondary limitation is the minimum excise. The research credit cannot be used to reduce a corporation’s tax liability below $456.7 This floor applies to each corporation independently, even within a combined reporting group.12
Sharing Excess Credits in a Combined Report
When corporations are engaged in a unitary business and file a combined report under M.G.L. c. 63, § 32B, the credits generated by one member may be shared with others.3 This sharing mechanism is one of the most powerful features of the Massachusetts tax code, allowing a research-heavy subsidiary to provide tax benefits to a profitable, non-research subsidiary.3
Priority of Application
The law establishes a clear “pecking order” for the use of credits in a combined group. A credit generated by an individual member corporation must first be applied against the excise attributable to that specific company.2 Only after the generator has utilized its generated credits to the maximum extent permitted (considering the 75% rule and the $456 floor) can the “excess” credits be shared with other group members.3
Sharing Eligibility and Limitations
The ability to receive a shared credit is limited by the recipient’s own tax profile. A member may only use a shared research credit if it would have been eligible to generate and use the credit itself under the provisions of M.G.L. c. 63.20 Historically, this prevented financial institutions from using shared research credits, as they were taxed under a different section of the law. However, recent legal developments have significantly altered this landscape.20
| Sharing Element | Rule/Requirement | Administrative Source |
| First Use | Credits must offset the generator’s own tax first. | M.G.L. c. 63, § 38M(e).2 |
| Excess Sharing | Only credits remaining after the generator’s use are shareable. | 830 CMR 63.32B.2(9).3 |
| Recipient Limits | Shared credits are subject to the recipient’s 75% limit and $456 floor. | 830 CMR 63.32B.2(9).3 |
| Non-Income Measure | Credits cannot offset the non-income (tangible property) measure of the excise. | 830 CMR 63.32B.2.25 |
Carryover Mechanisms: 15-Year vs. Indefinite Status
One of the most valuable aspects of the Massachusetts Research Credit is its carryover flexibility. When a credit generated by an individual member corporation cannot be used in the current year, it is preserved for future use.2 The law creates two distinct types of carryovers based on the reason for the credit’s disallowance.2
Standard 15-Year Carryover
Generally, any portion of the research credit that exceeds a corporation’s excise for the taxable year may be carried over for 15 succeeding taxable years.2 This carryover remains with the individual corporation that generated the credit.2
Indefinite (Non-Expiring) Carryover
A unique provision exists for credits disallowed specifically because of the 75% limitation rule.2 Any portion of a credit that could have been used but for the requirement that 25% of the excise over $25,000 remain payable can be carried forward indefinitely.2 These credits, formerly known as “unlimited” carryovers, are now reported on the Credit Manager Schedule as “non-expiring”.19 This is a critical distinction in tax planning, as it ensures that credits capped by the 75% rule never permanently “expire”.9
Administrative Compliance: Schedule RC and the Credit Manager Schedule (CMS)
To document the generation and sharing of the credit, the DOR requires the completion of several key tax schedules. Proper filing is essential, as the DOR may disallow credits for corporations that fail to enclose these schedules.28
Schedule RC (Research Credit)
Schedule RC is the primary form used to calculate the credit. It requires the taxpayer to identify whether they are using the Traditional Method or the Alternative Simplified Method.3 For corporations in an aggregated group, the Schedule RC reflects the group-level calculation, while identifying the individual member’s share of the resulting credit.3
Schedule CMS (Credit Manager Schedule)
Schedule CMS is the mandatory reporting tool for all Massachusetts tax credits. It tracks the life cycle of the credit from generation to application or sharing.28 The schedule is organized into sections that distinguish between credits generated by the taxpayer and credits received from other sources.28
- Section 1: Used to report non-refundable credits generated by the taxpayer that are being used to offset its own excise.28
- Section 3: Used to report credits received from pass-through entities or shared from other members of a combined group.28
- Credit Shared Column: A critical field on the CMS where the generator reports the amount of its excess credit that is being distributed to other members of the group.28
Schedule U-CS (Credit Sharing)
For corporations filing a combined report (Form 355U), Schedule U-CS must be filed by the member using the shared credit.20 This schedule validates the sharing transaction by identifying both the contributing member (the generator) and the recipient member.20
The Impact of Corporate Restructuring and Divestiture
A vital implication of the “generator” concept is seen when a corporation leaves a combined group. Because unused and unexpired credits are “generated by an individual member corporation,” they follow that specific corporation if it is sold or spun off.2
M.G.L. c. 63, § 38M(e) explicitly states that unused and unexpired credits shall be carried over by the individual corporation that generated them.2 This rule protects the value of the tax incentive for the entity that actually performed the R&D. If a group were to sell a subsidiary that had generated millions in R&D credits, those credits would typically leave the group and move with the subsidiary to its new owner.3
Sector-Specific Guidance: Life Sciences, Climatetech, and Financial Institutions
While the general rules of § 38M apply to all business corporations, the Commonwealth has introduced specialized programs and responded to judicial rulings that affect the R&D credit landscape.11
Life Sciences Tax Incentive Program
Through the Massachusetts Life Sciences Center (MLSC), certified life sciences companies may be eligible for a refund of their research credits.11 If a company has generated a credit but lacks the tax liability to use it, it can request a refund of up to 90% of the credit’s value.11 This turns a non-refundable credit into a vital source of non-dilutive capital for pre-revenue biotech firms.7
Financial Institutions and the State Street Decision
For decades, the DOR maintained that financial institutions (taxed under M.G.L. c. 63, § 2) were ineligible for the § 38M research credit, as the statute referred to “business corporations” (taxed under § 39).23 However, in 2024, the Appellate Tax Board issued a landmark ruling in State Street Corporation v. Commissioner of Revenue.23 The Board held that financial institutions are indeed “business corporations” for the purposes of § 38M and are entitled to generate and use research credits.23 The DOR has since issued guidance (TIR 25-3) acknowledging this shift, opening the door for banks and other financial services firms to claim substantial retroactive credits.23
The Climatetech Tax Incentive Program
In late 2024, the Economic Development Act established a new Climatetech Tax Incentive Program, modeled closely on the Life Sciences program.16 This includes a Climatetech Qualified Research Expenses Credit.16 While awarded at the discretion of the Massachusetts Clean Energy Technology Center (CEC), this credit follows the same generator-priority and sharing rules as the standard § 38M credit.16
Detailed Example: Credit Dynamics in a Multi-Entity Group
To illustrate the interplay of generation, allocation, sharing, and limitations, consider the following scenario involving a combined reporting group with three members: ResearchCo, SalesCo, and HoldingCo.
Scenario Data (Tax Year 2024)
| Member | Qualified Research Expenses | Separately Determined Excise | Credit Method |
| ResearchCo | $5,000,000 | $100,000 | ASM (10%) |
| SalesCo | $0 | $1,000,000 | N/A |
| HoldingCo | $0 | $10,000 | N/A |
| Group Total | $5,000,000 | $1,110,000 | N/A |
Step 1: Group Credit Calculation
Assuming ResearchCo’s 3-year average QREs were $3,000,000:
- Base: 50% of $3M = $1,500,000.
- Excess: $5,000,000 – $1,500,000 = $3,500,000.
- Group Credit: 10% of $3.5M = $350,000.
Step 2: Allocation to the Generator
Since ResearchCo provided 100% of the QREs, it is the “Individual Member Corporation” that generated the entire $350,000 credit.3
Step 3: Application to ResearchCo’s Excise
ResearchCo must use the credit against its own $100,000 excise first.3
- Threshold Allocation: ResearchCo’s share of the group’s $25,000 threshold is $(\$100,000 / \$1,110,000) \times \$25,000 = \$2,252$.3
- Offset Level 1: 100% of $2,252 = $2,252.
- Offset Level 2: 75% of remaining excise $(\$100,000 – \$2,252) = \$97,748 \times 0.75 = \$73,311$.
- Total Credit Used by ResearchCo: $2,252 + 73,311 = $75,563.
- Net Excise for ResearchCo: $100,000 – $75,563 = $24,437.
Step 4: Sharing the Excess with SalesCo
The excess credit generated by ResearchCo is $\$350,000 – \$75,563 = \$274,437$. This can be shared with SalesCo.3
- SalesCo Threshold: SalesCo’s share of the $25,000 threshold is $(\$1,000,000 / \$1,110,000) \times \$25,000 = \$22,522$.3
- Offset Level 1: 100% of $22,522 = $22,522.
- Offset Level 2: 75% of remaining excise $(\$1,000,000 – \$22,522) = \$977,478 \times 0.75 = \$733,108$.
- Max Sharing Capacity: $22,522 + 733,108 = $755,630.
- Credit Shared: ResearchCo shares its remaining $274,437 with SalesCo.
- Net Excise for SalesCo: $\$1,000,000 – \$274,437 = \$725,563$.
In this scenario, all generated credits were used in the current year. SalesCo would file Schedule U-CS to report the $274,437 received from ResearchCo, and ResearchCo would report the same amount as “Credit Shared” on its Schedule CMS.20
Economic Statistics and Future Outlook
The Massachusetts Research Credit represents a substantial tax expenditure for the Commonwealth. According to the Fiscal Year 2025 Tax Expenditure Budget, corporate excise credits (of which the R&D credit is a major component) are an essential tool for maintaining the state’s competitive edge in innovation.15
| Fiscal Year | Total Corporate Excise Expenditure (Millions) | Economic Focus |
| 2021 | $2,919.0 | Recovery and Innovation.34 |
| 2022 | $3,210.0 | Biotech Expansion.34 |
| 2023 | $3,466.8 | Digital Health/Clean Energy.34 |
| 2024 | $3,523.0 | Modern Defense/Climatetech.34 |
| 2025 (Projected) | $3,596.8 | Sustainability and AI.34 |
The continued expansion of the credit into climatetech and the resolution of the financial institution eligibility debate suggest a future where the research credit is more widely utilized across a broader array of industries.16 However, the foundational rules regarding the “generator” of the credit are likely to remain constant, as they provide a necessary link between the tax benefit and the physical conduct of research in the state.
Conclusion
The “Credit Generated by an Individual Member Corporation” serves as the vital legal and administrative link between the physical act of research and the financial benefit of the Massachusetts R&D tax credit. By prioritizing the generator’s use of the credit and preserving its ownership of carryforwards, the Commonwealth ensures that the incentive remains anchored to the entities that drive innovation. For businesses operating in Massachusetts, navigating the complexities of aggregation, allocation, and the 75% rule is essential for effective tax planning. As the state’s economy evolves and the definition of “qualified research” expands to meet new global challenges, the rigorous application of these generator-based rules will continue to provide the framework for one of the nation’s most robust innovation incentives. Through precise compliance with DOR guidance and strategic use of combined reporting, corporations can secure the long-term value of their R&D investments, ensuring that the fruits of Massachusetts-based research are reflected in a strengthened financial position.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
