Analysis of Excise Attributable to That Company within the Massachusetts Research and Development Tax Credit Framework

Excise Attributable to That Company refers to the specific portion of a combined group’s total corporate excise liability that is assigned to an individual member corporation based on its own apportioned income and activities. In the context of the Massachusetts Research and Development (R&D) Tax Credit, this figure serves as the essential benchmark for applying statutory credit limitations and determines the priority for applying credits before surplus amounts can be shared with other group members. 1

The determination of this figure is critical for taxpayers filing under the combined reporting regime, as it dictates the extent to which a corporation can utilize its generated research credits against its own tax burden and the threshold at which it may begin to offset the liabilities of its affiliates. 1 The interaction between the “separately determined excise” and the various caps—such as the $25,000 bracket and the 75 percent limitation—requires a nuanced understanding of both Massachusetts General Laws (M.G.L.) Chapter 63 and the supporting regulations promulgated by the Department of Revenue (DOR). 3

Statutory Framework of the Massachusetts Research Credit

The Massachusetts Research Credit, established under M.G.L. c. 63, § 38M, is a cornerstone of the Commonwealth’s innovation-led economic strategy. It provides a significant tax incentive for corporations that engage in qualified research and development activities within the state. 3 The statute is designed to encourage high-wage job creation and capital investment in sectors such as life sciences, technology, and advanced manufacturing. 1

Under § 38M, a domestic or foreign corporation is allowed a credit against its excise equal to the sum of 10 percent of the excess qualified research expenses (QREs) over a base amount, plus 15 percent of basic research payments. 3 The definitions of QREs and basic research payments are largely anchored to the federal definitions found in Internal Revenue Code (IRC) Section 41, as it was in effect on August 12, 1991. 3

Federal Conformity and the 1991 Frozen Date

A unique aspect of the Massachusetts research credit is its “frozen” conformity to the federal code. While many state tax provisions update automatically with federal changes, § 38M specifically references the IRC as of August 12, 1991. 3 This means that later federal amendments to Section 41, such as the permanent extension of the credit or changes to the definition of qualified research, do not necessarily apply in Massachusetts unless the state legislature takes affirmative action to adopt them. 4

For instance, the “Alternative Simplified Credit” (ASC) method was a later federal development that Massachusetts eventually adopted through specific legislative corrections, which were subsequently detailed in Department of Revenue guidance such as TIR 14-16. 1 This history highlights the importance of distinguishing between federal and state calculations when determining the amount of credit available to a corporation. 4

Qualified Research Activities and Massachusetts Nexus

To qualify for the credit, research activities must be conducted within the geographic boundaries of Massachusetts. 1 This nexus requirement is a fundamental departure from the federal credit, which applies to research conducted across the United States. 4 Qualified expenses generally fall into three categories:

Expense Category Massachusetts Requirement Percentage Inclusion
Internal Wages Paid to employees performing research in MA. 100%
Supplies Used in the conduct of research within MA. 100%
Contract Research Performed by third parties within MA. 65%
Computer Rental For computer time used in research in MA. 100%

Combined Reporting and the Unitary Business Concept

The concept of “Excise Attributable to That Company” emerged as a central technical issue with the adoption of mandatory combined reporting for tax years beginning on or after January 1, 2009. 9 Under M.G.L. c. 63, § 32B, corporations engaged in a unitary business must file a combined report (Form 355U) and calculate their income as a single group. 2

A “unitary business” is generally defined as one or more corporations that exhibit functional integration, centralization of management, and economies of scale. 9 When such a group exists, the income of all members—regardless of whether they have a physical presence in Massachusetts—is combined, and the group’s total income is then apportioned to the Commonwealth based on the collective Massachusetts activity of the taxable members. 9

The Separately Determined Excise

Even though the group’s income is combined, the final tax liability must be attributed back to the individual member corporations that are actually subject to the Massachusetts corporate excise. 1 This attributed amount is known as the “separately determined excise.” 1

The calculation of the excise attributable to a specific company involves several steps:

  1. Determine the member’s share of the combined group’s apportioned income. 1
  2. Apply the appropriate tax rate to that income share. 9
  3. Add any excise from non-unitary income or separate business activities. 9
  4. Add the non-income measure of the excise, which is based on the member’s own tangible property or net worth. 9
  5. Ensure the total meets the statutory minimum excise of $456. 1

This “separately determined excise” is the “excise attributable to that company” mentioned in the credit statutes. 1 It serves as the limit for how much credit the member can use before it must look to share its excess with other group members. 1

Mechanics of Aggregation for the Research Credit

While combined reporting is a method for filing a tax return, “aggregation” is a specific statutory requirement for calculating the research credit itself. 3 M.G.L. c. 63, § 38M(a) requires the commissioner of revenue to aggregate the activities of all corporations that are members of a controlled group. 3

This creates a two-tiered process: first, the credit is calculated for the entire group as if it were a single taxpayer, and then it is allocated to the individual members. 4

Aggregated Group Calculation

The group first calculates a total credit by aggregating all QREs and basic research payments made by all members, eliminating any intercompany payments to avoid duplication. 4 The aggregate excess expenses over the aggregate base amount determine the total credit available to the group. 4

The base amount calculation for an aggregated group involves determining a collective fixed-base percentage and collective average annual gross receipts. 4 If the group elects to use Massachusetts gross receipts, this must be applied consistently across the entire group. 4

Allocation of the Credit to Members

Once the total group credit is determined, it is allocated to each member corporation based on that member’s share of the group’s total QREs. 4 The formula for this attribution, found in Schedule RC, is:

$$Member\_Credit = Group\_Credit \times \frac{Member\_QREs}{Group\_QREs}$$

8

This ensures that the credit “belongs” to the entity that actually incurred the research expenses, which is a vital step before the credit can be applied against the “excise attributable to that company.” 1

Limitations on Applying the Credit Against Excise

The Massachusetts research credit is not an unlimited offset. The legislature has imposed several significant caps to ensure that corporations continue to pay a minimum level of tax and that the fiscal impact on the state budget is predictable. 1 These limitations apply directly to the excise attributable to each company. 1

The $25,000 Threshold and Group Sharing

Under § 38M(d), the research credit is limited to 100 percent of a corporation’s first $25,000 of excise, plus 75 percent of the excise that exceeds $25,000. 1 In the context of a combined return, this $25,000 threshold is not granted to every member corporation; instead, the group as a whole must share a single $25,000 bracket. 3

The portion of the $25,000 threshold allocated to an individual member is determined by the ratio of that member’s excise to the total excise of all group members. 3

Member Excise Component Formula for Allocation Resulting Benefit
First $25,000 (Group Total) Member Excise / Group Excise * $25,000 100% Credit Offset
Excess Excise Excise Attributable – Member’s Share of $25,000 75% Credit Offset

3

This allocation mechanism prevents a large corporate group from artificially increasing its credit capacity by splitting its operations into numerous small subsidiaries, each attempting to claim a separate $25,000 full-offset bracket. 4

The 75 Percent Limitation and Indefinite Carryover

The most restrictive limitation is the 75 percent rule. 1 Any excise liability exceeding the allocated portion of the $25,000 threshold can only be offset by the credit up to 75 percent. 3 The remaining 25 percent of the tax must be paid in cash (or offset by other non-limited credits). 4

Crucially, the law provides a safety valve for this limitation. 1 Any portion of the research credit that is disallowed specifically because of this 75 percent rule can be carried forward indefinitely. 1 This is a more favorable treatment than the standard 15-year carryover for credits that simply exceed the total tax liability. 1

The $456 Minimum Tax Floor

Finally, the research credit (and most other credits) cannot reduce a corporation’s total excise below the statutory minimum tax of $456. 1 This is an absolute floor for each member of a combined group that has nexus in Massachusetts. 10

Revenue Office Guidance: Applying the Law to Combined Returns

The Massachusetts Department of Revenue has provided extensive guidance through regulations and Technical Information Releases (TIRs) to clarify how these statutory rules apply to the modern combined filing environment. 1

Regulation 830 CMR 63.38M.1: The Primary Rule

This regulation provides the most detailed instructions for the research credit. 1 Paragraph (8) specifically addresses the priority of offset for combined groups. 1 It mandates that a member must first use its own research credit to offset its own “separately determined excise liability” for the taxable year. 1

Only after a member has applied its own credits—subject to its share of the $25,000 threshold and the 75 percent rule—can any “excess” credit be shared with other members of the unitary group. 1

TIR 09-18: Electronic Filing and Unitary Compliance

TIR 09-18 is the seminal guidance on the transition to combined reporting. 9 It establishes that all members of a combined group are jointly and severally liable for the group’s tax, but that credits remain an attribute of the individual member that earned them. 9 The TIR also mandates electronic filing via Form 355U, which uses sophisticated 2D barcodes and data flow logic to ensure that credits are correctly attributed and limited across all group members. 9

TIR 14-16: The Alternative Simplified Method

TIR 14-16 introduced the “Alternative Simplified Method” (ASC) for calculating the research credit. 1 This was a major shift for the revenue office, as it moved the state closer to the federal credit calculation introduced in the mid-2000s. 6 The ASC allows companies to calculate their credit based on 50 percent of their prior three-year average QREs, rather than the more cumbersome “fixed-base” method. 1

The transition to the ASC was phased in with increasing rates:

Applicable Years ASC Rate
2015 – 2017 5.0%
2018 – 2020 7.5%
2021 and Later 10.0%

1

The TIR clarifies that the ASC election is made at the group level for aggregated groups, further emphasizing the “unitary” nature of the credit calculation even as the “attribution” remains individual. 1

The Mechanism for Sharing Credits Between Members

One of the most powerful features of the Massachusetts research credit in a combined return is the ability to share credits between members of the same unitary group. 1 This is particularly beneficial for large organizations where one subsidiary may be the primary research engine (generating high credits but low income) while another is the primary sales engine (generating high income but low research). 1

Eligibility for Sharing

To share a credit, the following conditions must be met:

  1. Both the credit-generating member and the credit-using member must be part of the same unitary business. 1
  2. Both must be included in the same Massachusetts combined report (Form 355U). 1
  3. The generating member must have first used its own credits to the maximum extent allowed against its own “excise attributable to that company.” 1

Limits on the Using Member

The member receiving the shared credit is subject to the same limitations as if it had earned the credit itself. 1 This means the shared credit cannot reduce the receiving member’s excise below $456, and it remains subject to that member’s allocated share of the $25,000 threshold and the 75 percent limitation. 1

If a shared credit cannot be fully utilized by any member of the combined group in the current year, the unused portion does not become a “group asset.” 1 Instead, it reverts to the original generating member as a carryover for future years. 1

Detailed Example: Credit Attribution and Sharing

To understand how “Excise Attributable to That Company” functions in practice, consider a combined group with two taxable members: Innovate Corp and Sales Corp.

1. Excise Calculation (Separately Determined Excise)

The combined group has a total apportioned income that results in the following excise liabilities before any credits are applied:

  • Innovate Corp: $10,000 (Income measure) + $5,000 (Non-income measure) = $15,000
  • Sales Corp: $80,000 (Income measure) + $5,000 (Non-income measure) = $85,000
  • Total Group Excise: $100,000

In this scenario, the “Excise Attributable” to Innovate Corp is $15,000, and for Sales Corp, it is $85,000. 1

2. Credit Generation (Aggregated Basis)

Innovate Corp is the research arm and has incurred $1,000,000 in QREs. Sales Corp has zero QREs. The group credit is calculated as $100,000 (10% of $1,000,000 excess). 3

Since Innovate Corp generated 100% of the QREs, the entire $100,000 group credit is allocated to Innovate Corp. 4

3. Sharing the $25,000 Threshold

The group must share one $25,000 bracket based on their relative excise:

  • Innovate Corp Share: ($15,000 / $100,000) * $25,000 = $3,750
  • Sales Corp Share: ($85,000 / $100,000) * $25,000 = $21,250

4. Application of Credits to Innovate Corp

Innovate Corp must first apply its $100,000 credit against its own $15,000 excise:

  • 100% offset of its first $3,750 = $3,750
  • 75% offset of its remaining $11,250 ($15,000 – $3,750) = $8,437.50
  • Total Used by Innovate: $12,187.50
  • Final Excise for Innovate: $2,812.50 (which is above the $456 minimum)
  • Excess Credit Available to Share: $100,000 – $12,187.50 = $87,812.50

5. Sharing with Sales Corp

Innovate Corp now shares its excess credit with Sales Corp to offset Sales Corp’s $85,000 excise:

  • 100% offset of Sales Corp’s first $21,250 = $21,250
  • 75% offset of Sales Corp’s remaining $63,750 ($85,000 – $21,250) = $47,812.50
  • Total Shared Credit Used: $69,062.50
  • Final Excise for Sales Corp: $15,937.50

6. Carryover Tracking

  • Total Credit Generated: $100,000
  • Total Credit Used: $12,187.50 + $69,062.50 = $81,250
  • Remaining Carryover: $18,750

Of this $18,750 carryover, the portion that was disallowed due to the 75 percent rule can be carried forward indefinitely by Innovate Corp. 1

Filing and Compliance: Schedule RC and Schedule U-IC

Accurately reporting the research credit in a combined return requires the use of specialized schedules that track the attribution of excise and credits. 8

Schedule RC: Research Credit

Schedule RC is the primary form for calculating the credit. 4 Part 1 of the schedule tracks individual and group QREs, while Part 2 (ASC) or Part 3 (Standard Method) determines the total group credit and the portion attributable to the specific corporation filing the schedule. 8

Schedule U-IC: Combined Group Member Credits

For companies filing Form 355U, Schedule U-IC is where the “attribution” of the credit to the excise is finalized. 9 This schedule shows the credits being used against both the income and non-income measures of the excise. 9 It ensures that the sum of all credits used by a member does not violate the 32C limitation (50% of excise) or the specific 38M limitation (75% of excise). 3

Electronic Integration and 2D Barcoding

Because of the complexity of these calculations, Massachusetts requires software-generated returns to include 2D barcodes. 11 These barcodes encode the data from all schedules, ensuring that a change in “Excise Attributable to That Company” on one page (such as a change in property valuation) automatically ripples through to the credit limitation calculations on Schedule RC and Schedule U-IC. 11

Economic Impact and Sectoral Insights

The Massachusetts Department of Revenue’s transparency reports provide a high-level view of how the research credit is utilized across the state’s economy. 12 The data indicates that the credit is highly concentrated in sectors that require long lead times for product development and significant capital outlays. 5

Life Sciences and Biotechnology

The life sciences sector is the primary beneficiary of the research credit. 5 Many of these firms operate as part of larger global unitary groups. The ability to attribute excise and share credits is vital for these companies, as they often have specific legal entities dedicated solely to high-risk research. 1 The indefinite carryover provision is particularly tailored to this sector, where a company may spend a decade in the research phase before generating any taxable income. 5

Climatetech and Clean Energy

Recent legislative initiatives have sought to expand the success of the R&D credit into the climatetech sector. 13 This includes new refundable credits for climatetech facilities and jobs. 13 While these are distinct from the § 38M research credit, they are designed to work alongside it, often utilizing the same combined reporting framework to ensure that “excise attributable” to these green energy firms can be effectively managed within a corporate group. 13

Defense-Related Activities

M.G.L. c. 63, § 38M(i) allows taxpayers to elect to calculate their credit separately for defense-related activities. 3 This provision is a legacy of the state’s strong defense contracting sector. It allows companies to “bucket” their research, ensuring that a downturn in civilian R&D does not dilute the credits earned through defense innovation. 3

Conclusion: Strategic Implications of Credit Attribution

The meaning of “Excise Attributable to That Company” is a technical necessity that enables the complex engine of the Massachusetts research credit to function within a combined reporting system. It provides the legal “hook” that allows the state to track credit usage at the individual member level while still providing the group-wide benefits of a unitary business model. 1

For the modern enterprise, navigating this framework requires more than just identifying research expenses; it requires a strategic understanding of how those expenses are allocated across a corporate group and how the resulting credits interact with the tax liabilities of every member. 4 The interaction of the shared $25,000 threshold, the 75 percent limitation, and the indefinite carryover rules makes the Massachusetts research credit one of the most sophisticated—and rewarding—tax incentives in the United States. 1

As the Commonwealth continues to evolve its tax code to support emerging technologies like fusion energy and agricultural technology, the established principles of credit attribution and combined reporting will remain the foundation upon which these new incentives are built. 13 Taxpayers who master the “separately determined excise” calculation will be best positioned to maximize their return on research investment and contribute to the ongoing growth of the Massachusetts innovation economy. 5

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.
