Tangible Property Used in Manufacturing: Analysis of Massachusetts Chapter 63 and the Research and Development Tax Credit

Tangible property used in manufacturing is the physical capital, including machinery and floor space, substantially transforming materials into new products for sale. Within the Massachusetts R&D framework, this classification determines eligibility for the Investment Tax Credit and shapes the corporate excise apportionment.

The intersection of physical manufacturing assets and intangible intellectual property development creates a complex tax environment in the Commonwealth of Massachusetts. Under Massachusetts General Laws (M.G.L.) Chapter 63, the classification of a business as a “manufacturing corporation” or a “research and development (R&D) corporation” is a critical determination that unlocks specific tax expenditures, including the 3% Investment Tax Credit (ITC) and exemptions from local property taxes. The definition of “tangible property used in manufacturing” serves as the primary quantitative metric for these classifications, requiring a meticulous accounting of how every square foot of real estate and every piece of equipment is utilized within the state. As the Department of Revenue (DOR) continues to refine its guidance through Technical Information Releases (TIRs), Letter Rulings, and Administrative Procedures, the distinction between a transformative manufacturing process and a purely investigative research activity has become increasingly nuanced, particularly for high-technology sectors like software development and biotechnology.

The Statutory Definition of Manufacturing Activity

The threshold for what constitutes “manufacturing” in Massachusetts is built upon the “new name, nature, and use” test. According to 830 CMR 58.2.1 and 830 CMR 63.38.1, manufacturing is the process of substantially transforming raw or finished physical materials by hand or machinery, and through human skill and knowledge, into a new product possessing a new name, nature, and adapted to a new use.1 This transformation must be substantial; minor assembly or packaging typically does not meet the standard. The Commissioner of Revenue examines the facts and circumstances of each case, looking for indicators of transformation such as chemical change, which is more likely to be classified as manufacturing than mere physical change.2

For the purposes of the R&D credit and other corporate excise benefits, the term “tangible property” encompasses both real estate and personal property. Real property includes buildings and structural components, while personal property includes machinery, equipment, tools, and supplies.2 The classification of this property is determined by its actual use in the Commonwealth during the taxable year.

The Quantitative Substantiality Tests

A corporation is not automatically granted manufacturing status simply by engaging in some manufacturing activity. Instead, it must be engaged in manufacturing in a “substantial” part. M.G.L. c. 63, § 42B and § 38 provide five distinct tests to determine substantiality. A corporation is considered a “Section 38 manufacturer” if it meets any one of these criteria during the taxable year.1

The reliance on tangible property in Tests 3 and 4 highlights why the valuation and classification of physical assets are paramount for tax planning. For businesses with low payroll costs or fluctuating revenue, the 35% tangible property threshold (Test 4) often becomes the most reliable path to securing manufacturing status.2

The Tangible Property Fraction and Valuation Rules

The mechanism for determining the amount of tangible property used in manufacturing is the “tangible property fraction,” as detailed in 830 CMR 58.2.1(6)(e). This fraction is used to calculate the percentage of a corporation’s Massachusetts assets dedicated to the manufacturing process.2

Calculating the Numerator

The numerator of the tangible property fraction is the value of property used or purchased for use in manufacturing in Massachusetts by the corporation during the previous tax year.2 This includes:

• Real Property: Only the specific floor space devoted to actual manufacturing. This excludes floor space for executive or administrative offices, cafeterias, warehouses for finished goods, or parking lots.2
• Personal Property: Machinery and equipment used directly in the transformative process.

Calculating the Denominator

The denominator is the value of all property used or purchased for use in Massachusetts during the previous tax year.2 In cases where a company has operations both within and outside the state, the denominator does not include the value of an in-state facility used as a corporate headquarters.2

Valuation Methodology

For the purposes of this fraction, Massachusetts requires specific valuation rules that differ from standard book value or fair market value in some instances.

The 8x rental multiplier is a standard feature of Massachusetts apportionment rules designed to equalize the “value” of leased assets with owned assets in the eyes of the tax authority.2

Interaction with the Massachusetts R&D Tax Credit (§ 38M)

The Massachusetts Research Credit, governed by M.G.L. c. 63, § 38M, is a powerful incentive for companies conducting qualified research within the state. While the credit is primarily calculated based on incremental spending on wages, supplies, and contract research, its application is deeply intertwined with the tangible property rules.11

Qualified Research Expenses (QREs)

Under 830 CMR 63.38M.1, the state mirrors the federal definition of QREs found in Section 41(b) of the Internal Revenue Code (IRC). However, these expenses must be incurred for research activity conducted in Massachusetts.11 Tangible items that qualify as QREs include:

• Supplies: Materials, prototypes, and other items consumed in the research process in Massachusetts.11
• Computer Rentals: Costs for the right to use computers for research purposes, provided the hardware is physically located in Massachusetts.11

Crucially, the § 38M R&D credit does not apply to depreciable tangible property like buildings or heavy machinery. Instead, the law creates a bifurcated system: the R&D credit covers the “burn” of research (wages and consumables), while the Investment Tax Credit covers the “infrastructure” (the property).16

Classification as an R&D Corporation

Just as manufacturing status is determined by tangible property, so too is the status of an “R&D corporation.” Under M.G.L. c. 63, § 42B, a corporation is considered an R&D corporation if its “principal activity” in the Commonwealth is research and development.5 This is determined by a “receipts test” or an “expenditures test.”

• Receipts Test: More than two-thirds of Massachusetts receipts must be derived from R&D.19
• Expenditures Test: More than two-thirds of Massachusetts expenditures must be allocable to R&D activities.19

If a corporation is primarily an R&D corporation but also conducts manufacturing, it must exclude manufacturing expenditures from the R&D side of the ledger for the purpose of the two-thirds assessment.5 This prevents a company from “double-counting” its activities to meet both definitions simultaneously for the same dollar spent.

The Investment Tax Credit (ITC) for Manufacturing and R&D

One of the primary benefits of being classified as a manufacturing or R&D corporation is the 3% Investment Tax Credit under M.G.L. c. 63, § 31A.3 This credit is directly applied against the corporate excise.

Qualifying Tangible Property for the ITC

To earn the 3% ITC, the property must be:

1. Depreciable: Tangible personal property or other tangible property, including buildings and structural components.3
2. Long-Lived: A useful life of four years or more.3
3. In-State: Used and located in Massachusetts on the last day of the taxable year.22
4. Ownership/Lease: Owned or leased by the corporation (specific rules apply for leasehold improvements).22

Coordination of R&D and ITC Benefits

A sophisticated business in Massachusetts can often “layer” these credits. For example, a manufacturer building a new factory with an integrated R&D lab can claim the 3% ITC on the cost of the entire facility and the machinery within it, while simultaneously claiming the 10% R&D credit on the salaries of the engineers working in that lab and the materials used to build prototypes.16

This coordination ensures that both the “bricks and mortar” and the “human capital” of innovation are subsidized by the Commonwealth.3

Local Revenue Office Guidance and Administrative Rulings

The Massachusetts Department of Revenue has issued extensive guidance through Letter Rulings and Directives to clarify how these definitions apply in a modern economy.

Directive 00-4: Entity Classification

A major point of clarification involves the legal form of the business. According to Directive 00-4, an LLC that elects to be taxed as a corporation can receive manufacturing corporation classification if it meets the requirements of 830 CMR 58.2.1.23 However, an LLC taxed as a partnership or a disregarded entity cannot be a manufacturing corporation itself.23 Instead, its manufacturing activities flow through to its corporate owners, who can then use those activities to meet their own substantiality tests.24

TIR 08-2: The “Essential and Integral” Doctrine

Technical Information Release (TIR) 08-2 addressed several Appellate Tax Board decisions, including The First Years, Inc. and Onex Communications Corp..25 These cases explored whether a company that outsources its actual manufacturing can still be a “manufacturing corporation.” The Board ruled, and the Commissioner agreed, that if a taxpayer’s design and creation of products is “essential and integral” to producing and bringing them to market, those activities constitute manufacturing.25 This is critical for R&D-heavy firms that create complex prototypes and blueprints but use contract manufacturers for mass production.

Letter Ruling 02-12: Principal Activity

In Letter Ruling 02-12, the DOR examined whether a company’s “principal activity” in Massachusetts was R&D.18 The ruling established that if the ultimate goal of the activity is the development of products “capable of being manufactured in this Commonwealth,” then the activity qualifies as R&D even if the manufacturing happens later or elsewhere.18 This forward-looking definition protects companies in the early “experimental or laboratory” stages of development.

Industry-Specific Impact: Life Sciences and Software

Massachusetts has tailored its tax code to support its most dominant innovation clusters: life sciences and standardized software.

The Life Sciences Incentive Program

Certified life sciences companies have access to enhanced benefits, including a 10% Investment Tax Credit (compared to the standard 3%) for property like labs and equipment.16 Furthermore, while the standard R&D credit is non-refundable, certified life sciences companies may apply for a 90% refund of unused R&D credits.11 This unique provision turns a tax credit into a direct capital grant for startups with significant tangible R&D property but no current tax liability.

Software as Tangible Property (The Akamai Decision)

In Akamai Technologies, Inc. v. Commissioner of Revenue, the Appellate Tax Board expanded the definition of manufacturing to include remotely accessed software (SaaS). The state had argued that because customers did not download the software, it was a “service” rather than “tangible personal property”.9 The Board disagreed, confirming that the development of standardized software is manufacturing regardless of the delivery method. This ruling allows thousands of Massachusetts SaaS companies to qualify for the property tax exemptions and ITCs previously reserved for physical hardware manufacturers.9

Procedural Requirements and Recordkeeping

To claim these benefits, a corporation must follow strict procedural steps mandated by the DOR.

1. Form 355Q Application: Corporations seeking manufacturing status must file this application by January 31 of the calendar year.24 The DOR then publishes an “Annual List of Corporations” which local assessors use to grant property tax exemptions.23
2. Usage Proration: For property used both for R&D and for other purposes, or used both inside and outside the state, expenses must be prorated. This is often done based on the ratio of “days used for research in Massachusetts” to total “days used for research everywhere”.12
3. Deduction Reduction: If a corporation claims the R&D credit, it must reduce its overall deduction for research expenses on its corporate excise return by the amount of the credit determined for the year.13

Future Outlook and the 2025 Apportionment Shift

A significant change to the Massachusetts tax landscape is set for 2025. Effective January 1, 2025, all corporations doing business in Massachusetts and at least one other state must use “Single Sales Factor” apportionment.10

Prior to this change, “manufacturing corporation” status was a primary gatekeeper to using single sales factor apportionment (rather than the three-factor property/payroll/sales formula). By 2025, while the single sales factor becomes universal, the manufacturing classification will remain essential for:

• Local Property Tax Exemption: Exempting machinery from taxation.19
• The 3% ITC: Only manufacturers, R&D corporations, and those in fishing/agriculture can claim the credit for tangible property.3
• Sales/Use Tax Exemptions: Under G.L. c. 64H, § 6(r) and (s), for machinery and materials used in R&D.19

Detailed Example: Application of Rules to “Innovation Corp”

To synthesize these rules, consider a hypothetical example based on the “Fraction Corporation” model provided in DOR regulation 830 CMR 58.2.1(6)(e).2

Innovation Corp owns a 20,000 sq. ft. facility in Boston valued at $2,000,000 (original cost).

• Floor Space Usage:

• Manufacturing floor (assembling medical devices): 8,000 sq. ft.
• R&D Lab (developing a new prototype): 6,000 sq. ft.
• Administrative Offices: 4,000 sq. ft.
• Employee Breakroom: 2,000 sq. ft.

• Personal Property:

• Manufacturing Machinery: $1,500,000.
• Lab Equipment (Depreciable): $1,000,000.
• Office Furniture: $500,000.

Step 1: Calculate Real Property for the Manufacturing Numerator

The manufacturing area is 8,000 sq. ft. Out of 20,000 sq. ft., this is 40%.

Calculation: $0.40 \times \$2,000,000 = \$800,000$.

Step 2: Calculate Personal Property for the Manufacturing Numerator

Only the manufacturing machinery is included.

Calculation: $1,500,000.

Step 3: Calculate the Tangible Property Fraction

• Numerator: $800,000 (Real) + $1,500,000 (Personal) = $2,300,000.
• Denominator: $2,000,000 (Total Real) + $3,000,000 (Total Personal) = $5,000,000.
• Fraction: $\frac{\$2,300,000}{\$5,000,000} = 46\%$.

Conclusion for Innovation Corp:

Because 46% exceeds the 35% threshold for Test 4, Innovation Corp is classified as a manufacturing corporation.2 It can now claim:

1. ITC: 3% of the cost of the manufacturing machinery and the lab equipment (since R&D corporations also qualify for ITC).3
2. R&D Credit: 10% on the incremental cost of the salaries of the researchers in the lab and any consumable supplies used in the R&D process.11
3. Property Tax: Exemption on the $1,500,000 of machinery from local property taxes.19

Statistical Context and Fiscal Impact

The effectiveness of these incentives is reflected in the scale of tax revenue foregone by the Commonwealth. In FY 2024, the “Credits Against Tax” for corporations (which includes the R&D credit and ITC) represented approximately $894.7 million in tax expenditures.4

The steady growth in these figures suggests a corresponding increase in the level of “tangible property used in manufacturing” and R&D activity within the state.4

Strategic Conclusion

For a professional navigating the Massachusetts corporate excise, the definition of “tangible property used in manufacturing” is far more than a semantic hurdle; it is a fundamental driver of tax efficiency. The state’s tax regime is uniquely structured to reward firms that maintain physical production footprints in conjunction with high-level research activities. By understanding the 8x rental multiplier, the floor space proration rules, and the “essential and integral” doctrine for outsourced production, tax planners can ensure that a corporation is correctly classified to maximize its eligibility for the R&D credit and the 3% ITC. As the 2025 shift to universal single sales factor apportionment approaches, the strategic focus will narrow onto these property-based incentives and local tax exemptions, making accurate asset classification more vital than ever for the long-term success of innovative firms in the Commonwealth.

The interaction of these laws creates a robust support system for the innovation economy. By subsidizing the tangible costs of doing business through the ITC and property tax exemptions, and subsidizing the human and material costs of discovery through the R&D credit, Massachusetts remains a premier destination for sectors where the laboratory and the factory floor are inextricably linked. Success in this environment requires constant vigilance regarding DOR guidance and a meticulous approach to documenting the physical manifestation of corporate innovation.
