Structural Analysis of the Nonrefundable Research and Development Tax Credit in Massachusetts

A nonrefundable tax credit in Massachusetts is a fiscal incentive that directly reduces a corporation’s excise liability but does not permit a cash refund if the credit exceeds the tax owed. Any unused portion of the credit must be carried forward to offset future liabilities, subject to specific statutory durations and percentage-based utilization caps.

The Massachusetts Research and Development (R&D) Tax Credit, established under Massachusetts General Laws (M.G.L.) c. 63, § 38M, serves as a primary mechanism for the Commonwealth to incentivize domestic innovation and high-tech employment.1 Unlike a tax deduction, which reduces the income upon which tax is calculated, a credit provides a dollar-for-dollar reduction of the final tax bill.3 However, the “nonrefundable” designation carries significant weight in the corporate excise framework, as it dictates that the Commonwealth will not act as a source of immediate liquidity for a pre-revenue or loss-making entity unless that entity qualifies for highly specific exceptions, such as those found in the life sciences or climatetech sectors.1 For the vast majority of general business corporations, the nonrefundable status implies that the credit is a deferred asset, the value of which is contingent upon the corporation’s ability to generate future taxable excise in excess of the statutory minimum and specific utilization thresholds.2

Statutory Foundation and the Legal Meaning of Nonrefundability

The core of the Massachusetts R&D credit is codified in M.G.L. c. 63, § 38M, which allows a business corporation a credit against its excise due equal to a percentage of its qualified research expenses (QREs).8 The term “nonrefundable” is functionally defined through the interaction of subsection (c), (d), and (g) of the statute, which collectively limit the credit’s immediate use to the reduction of tax liability while forbidding the issuance of a refund for any excess.8

In the context of the corporate excise, which includes both an income measure and a non-income (property or net worth) measure, a nonrefundable credit applies to the total excise liability.10 However, even if a corporation has a substantial credit balance, the law prevents the credit from reducing the tax below a certain floor. This floor is the greater of the minimum excise, currently $456, or the limitations imposed by the 75% rule on excise exceeding $25,000.2 This structure ensures that every corporation maintaining a nexus in Massachusetts contributes a baseline amount to the state’s revenue, regardless of the intensity of its R&D investment.11

Primary Limitations on Nonrefundable Credit Utilization

The nonrefundable nature of the credit is not a simple “all-or-nothing” rule. It is a nuanced, bracketed system where the utility of the credit changes as the tax liability increases. The Department of Revenue (DOR) provides exhaustive guidance on these limitations through its regulations at 830 CMR 63.38M.1(8).10

The 75% limitation creates a situation where a corporation with a high tax liability can never use its nonrefundable R&D credits to eliminate its tax bill entirely. For example, if a corporation has a $125,000 excise liability, it can use credits to cover the first $25,000 (100%) and then 75% of the remaining $100,000 ($75,000).6 This results in a maximum credit use of $100,000, leaving a $25,000 cash tax payment required. This “forced” cash payment is a hallmark of the nonrefundable regime, designed to provide a steady stream of revenue to the Commonwealth even from its most successful innovators.12

Massachusetts Qualified Research Expenses: The Geographical Nexus

A credit can only be claimed for expenses that have a direct geographical nexus to the Commonwealth. The nonrefundable credit is restricted to “Massachusetts qualified research expenses,” defined as expenses that meet the requirements of IRC § 41(b) and were incurred for research activity conducted in Massachusetts.10

Categories of Eligible Expenditures

The state revenue office guidance clarifies that only specific costs qualify, and they must be strictly partitioned from federal R&D totals if a company operates in multiple states.15

• Wages for Qualified Services: This includes the portion of salaries paid to employees for direct performance, supervision, or support of research within the state.6
• Supplies Used in Research: Tangible property (excluding land and improvements) used or consumed during the R&D process in a Massachusetts facility.6
• Computer Rental and Maintenance: Costs associated with the right to use computers for research purposes, provided the hardware is located in Massachusetts.10
• Contract Research (65% Rule): Sixty-five percent of the fees paid to outside contractors are eligible, but only if the actual research activity occurred at a facility in Massachusetts.10

For employees who split their time between Massachusetts and other locations, the DOR requires a strict proration based on the ratio of days worked in-state to the total number of days the service was performed.15 This requirement places a high administrative burden on corporations to track personnel movement and project locations, as any misallocation could lead to a denial of the credit during a state audit.2

Methodologies for Credit Calculation

Massachusetts offers two primary methods for calculating the credit, both of which result in a nonrefundable asset. The choice of method affects the amount of the credit and, consequently, the amount that may be subject to carryforward limitations.2

The Regular (Traditional) Method

The traditional method focuses on incremental research spending. The credit is equal to 10% of the current year’s QREs that exceed a calculated “base amount,” plus 15% of basic research payments.8 The calculation of the base amount is a complex multi-year process:

1. Average Annual Gross Receipts: The average gross receipts for the four taxable years preceding the credit year.8
2. Fixed-Base Ratio: Determined by dividing the QREs for the third and fourth years preceding the credit year by the gross receipts for those same years, capped at 16%.14
3. The Formula: The Base Amount is the product of these two figures, but it cannot be less than 50% of the current year’s QREs.10

The Alternative Simplified Credit (ASC) Method

Recognizing that the traditional method’s reliance on gross receipts was often burdensome or disadvantageous for startups, Massachusetts introduced the ASC in 2015.2 Under this method, the credit is 10% (for years beginning on or after January 1, 2021) of the current year’s QREs that exceed 50% of the average QREs from the three preceding taxable years.2

Administrative Guidance: The Role of TIRs and Directives

The Massachusetts Department of Revenue communicates its interpretation of the R&D credit law through Technical Information Releases (TIRs) and Directives. These documents are essential for understanding how the nonrefundable status is applied to specific corporate structures and scenarios.

TIR 91-8 and TIR 14-16: The Framework for Compliance

TIR 91-8 was the seminal document explaining how the newly enacted credit would be claimed and recomputed based on federal accounting standards.23 Subsequent guidance in TIR 14-16 provided the bridge for corporations moving toward the ASC method, detailing the election process and the binding nature of such choices.6 A critical takeaway from these releases is that while Massachusetts follows many federal definitions under IRC § 41, it periodically “decouples” from federal changes to maintain state-level fiscal control.12

Directive 88-23: The Priority of Credit Application

Because a nonrefundable credit can only be used to the extent of tax liability, a corporation with multiple credits must decide which to use first. Directive 88-23 establishes a “priority of use” to prevent credits with shorter expiration dates from lapsing.24

1. Expiring Credits: Credits that will lapse in the current year (e.g., Vanpool credits or 3-year ITC carryovers).24
2. R&D Credits (15-Year Carryover): These are generally applied after credits with shorter windows.24
3. Unlimited Carryovers: Credits disallowed by the 75% limitation rule are the last to be applied, as they never expire and thus represent the most “durable” tax asset.2

TIR 25-3: Financial Institutions and the R&D Credit

A significant recent development in Massachusetts guidance is TIR 25-3, which addresses the eligibility of financial institutions to claim the R&D credit.2 Historically, the credit was viewed as a tool for manufacturing and biotech, but the DOR now clarifies that the software and system innovations within the financial sector qualify, provided the activities meet the statutory four-part test for R&D.2

Carryforward Mechanics: 15-Year vs. Indefinite

The most complex feature of the Massachusetts nonrefundable credit is the dual-track carryforward system. The reason why a credit cannot be used in a current year determines how long it remains available for future use.6

The 15-Year General Carryover

If a corporation’s credit exceeds its total tax liability (for example, a company with $0 liability and a $50,000 credit), the unused portion is carried forward for 15 years.7 If it is not used within that 15-year window, the credit expires and is lost forever. This applies to the portion of the credit that exceeds the “excise for the taxable year”.8

The Indefinite Carryover for Disallowed Portions

There is a unique provision in M.G.L. c. 63, § 38M(g) and 830 CMR 63.38M.1(10) for credits that are disallowed specifically because of the 75% limitation on excise over $25,000.8 Any credit amount that would have been used but was blocked by that 75% cap can be carried forward indefinitely.2

This distinction creates two “buckets” of credits on a corporation’s balance sheet:

• Bucket A (Expiring): Standard excess credits (15-year life).2
• Bucket B (Non-Expiring): “75% rule” disallowed credits (Indefinite life).2

For tax planning, this means that even if a company has significant tax bills, it will likely build up a permanent “non-expiring” credit balance that can be utilized in future years where its R&D spending might decline but its tax liability remains.2

Exceptions: When the Credit Becomes Refundable

While the R&D credit is nonrefundable by default, Massachusetts has created specialized programs where the credit can be converted into cash. These programs are highly regulated and require separate certification.1

Life Sciences Tax Incentive Program

Under the Massachusetts Life Sciences Center (MLSC), certified life sciences companies can elect to receive a refund of their unused Section 38M research credits.1

• Refund Rate: 90% of the balance of the remaining credits.5
• Conditions: The company must be certified by the MLSC, meet job creation targets, and have its refund specifically authorized by the Center in consultation with the DOR.5
• Trade-off: If a company elects a refund, it waives the right to carry those credits forward to future years.29

Climatetech Capital Investment Credit

Recent legislation (TIR 25-5) introduced a similar refundable component for climatetech companies.4 If a certified climatetech company’s credit exceeds its liability, 90% of the excess can be refunded, provided the company creates at least five net new full-time employees in the state.4

Combined Reporting and Aggregate Groups

For corporations that are part of a larger corporate structure and file a combined report (Form 355U), the nonrefundable credit enters an even more complex regulatory environment.4

Sharing of Nonrefundable Credits

Under 830 CMR 63.32B.2, a credit generated by an individual member of a combined group must first be applied against that member’s own excise liability.4 If the member has an excess credit, it may share that credit with other members of the group.2 However, the sharing is subject to the same nonrefundable limitations:

1. The $25,000 threshold (the amount offset at 100%) is shared among the entire aggregated group.2
2. The credit can only be shared with a member to the extent that member has liability that can be offset under the 75% rule.2
3. Any unused credit remains an asset of the member that originally generated it for carryforward purposes.4

This sharing mechanism is a vital tool for large corporate groups, allowing them to shift credits from research-heavy subsidiaries (which may have little income) to sales-heavy subsidiaries (which have high excise liability).12

Quantitative Example: Applying the Nonrefundable Credit

To understand the practical application of these rules, consider “TechDynamics Inc.,” a Massachusetts-based software firm filing for the 2024 tax year.

Scenario Parameters

• Excise Liability (Before Credits): $250,000
• Massachusetts QREs (Current Year): $2,000,000
• Historical Base Amount (under Traditional Method): $1,200,000
• Prior Year R&D Credit Carryforward: $50,000

Step 1: Calculate the New Credit Amount

Using the Traditional Method:

$\text{Credit} = 10\% \times (\text{QREs} – \text{Base Amount})$

$\text{Credit} = 10\% \times (\$2,000,000 – \$1,200,000) = \$80,000$.8

Step 2: Determine Total Credits Available

$\text{Total Credits} = \text{Current Year } (\$80,000) + \text{Carryforward } (\$50,000) = \$130,000$.25

Step 3: Apply the Utilization Limitations

The first $25,000 of excise is offset at 100%.

Remaining excise: $\$250,000 – \$25,000 = \$225,000$.

The excise over $25,000 can be offset by 75%.

$\text{Allowed Offset} = 75\% \times \$225,000 = \$168,750$.

$\text{Total Maximum Credit Use} = \$25,000 + \$168,750 = \$193,750$.2

Step 4: Final Settlement

Since the total available credits ($130,000) are less than the maximum allowed use ($193,750), TechDynamics can use all $130,000 in the current year.

$\text{Final Excise Due} = \$250,000 – \$130,000 = \$120,000$.

The company has successfully used its credits, but because they were nonrefundable and limited by the 75% rule, it still owes a cash balance of $120,000.2

Variation: High Credit Scenario

If TechDynamics had $300,000 in credits:

1. It would use the maximum allowed of $193,750.
2. The remaining $\$300,000 – \$193,750 = \$106,250$ would be carried forward.
3. The portion disallowed by the 75% rule ($\$225,000 – \$168,750 = \$56,250$) would be carried forward indefinitely.
4. The remaining portion ($\$106,250 – \$56,250 = \$50,000$) would have a 15-year expiration.2

Fiscal and Economic Context: State Expenditure Data

The nonrefundable R&D credit is one of the Commonwealth’s largest “tax expenditures,” representing revenue foregone to achieve policy goals. According to the Massachusetts Tax Expenditure Budget, the cost of this credit has grown significantly alongside the state’s tech boom.34

34

This increasing trend underscores the effectiveness of the credit in attracting and retaining research-focused companies, but it also explains why the state maintains the 75% limitation. If the credit were fully refundable and uncapped, the fiscal impact during economic downturns (when many companies move into loss positions) could be destabilizing for the state budget.36

Procedural Requirements: Claiming the Credit

To successfully claim the nonrefundable credit, a corporation must follow a strict procedural path via MassTaxConnect and the submission of Schedule RC.18

1. Identify Qualified Activities: Perform a “Four-Part Test” on projects to ensure they meet federal and state definitions of research.19
2. Calculate Credit on Schedule RC: Detail wages, supplies, and contract costs specifically for Massachusetts locations.14
3. Complete Schedule CMS: The Credit Manager Schedule (CMS) is where the corporation tracks the available, used, shared, and carried forward amounts.25
4. Reporting Carryovers: Credits disallowed by the 75% rule should be identified as “non-expiring” or “unlimited” on the CMS to ensure they are tracked correctly in future years.2

Failure to provide a completed Schedule RC with the return is a common cause for credit denial.2 Furthermore, corporations must be prepared for the “Recapture” provisions: if a project’s certification is revoked (common in life sciences or EDIP projects), the credits previously claimed may be added back as additional tax in the year of revocation.29

Strategic Insights for Tax Planning

The nonrefundable nature of the credit necessitates several strategic considerations for business owners and tax professionals in the Commonwealth.

The Decoupling of Section 174

A major point of divergence between federal and state law involves the capitalization of R&D expenses. While the federal government (under the TCJA) now requires corporations to capitalize and amortize R&D costs over 5 years, Massachusetts has periodically addressed this through its conformity rules.28 TIR 25-5 provides updated guidance on how the state will treat these costs, and businesses must ensure that their Massachusetts calculation reflects state-specific expensing rules rather than a simple mirror of the federal Form 6765.4

Managing the “Minimum Tax” Trap

Because the credit cannot reduce the tax below $456, small startups with minimal property and no income may find that their credits are largely useless in the short term.2 In these cases, it is vital to track the credits diligently for 15 years, as they represent a significant offset once the company reaches profitability or scales its tangible assets.2

The Value of the ASC Election

The election to use the ASC method is intended to be a long-term choice.2 Corporations should model both methods across a 5-year projection to determine which provides the best long-term shield. While the traditional method may look better in a year with high university spending, the ASC method’s lack of a gross-receipts-based floor often makes it more resilient in the face of rapid revenue growth.2

Conclusion: The Structural Impact of Nonrefundability

The Massachusetts nonrefundable R&D tax credit is a powerful, yet strictly governed, tool for economic growth. Its meaning is found in the balance between reward and restriction: it rewards high-intensity innovation with significant tax offsets but restricts that offset through the $25,000 threshold and the 75% limitation rule to protect the state’s revenue baseline. By providing a 15-year carryforward for standard excess and an indefinite carryforward for credits capped by the 75% rule, the Commonwealth has created a regime that incentivizes companies to stay and grow in Massachusetts for the long term.

Understanding the administrative guidance—from the early clarifications of TIR 91-8 to the modern sector-specific rules of the MLSC—is essential for any corporation seeking to monetize its research efforts. While the nonrefundable status may seem like a barrier for pre-revenue companies, it ultimately functions as a “deferred dividend” for those that successfully commercialize their research within the borders of the Commonwealth. Success in navigating this environment requires a meticulous approach to geographical expense tracking, an informed choice of calculation methodology, and a disciplined management of the Credit Manager Schedule over the lifecycle of the business.
