R&D Tax Credit vs R&D Tax Deduction
R&D Tax Credit vs R&D Tax Deduction
Summary
The R&D tax credit and R&D tax deduction are two separate tax benefits governed by different sections of the tax code. The credit is governed by IRC §41, while for tax years beginning after December 31, 2024, the domestic R&D deduction is generally governed by IRC §174A.
In many cases a business can claim both the credit and the deduction on the same research spending, but the tax code requires a coordination adjustment under §280C to ensure the taxpayer does not benefit twice from the same expense.
The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, is where today's rules come from. It created IRC §174A, which restored immediate expensing for domestic research costs after several years of mandatory amortization under the Tax Cuts and Jobs Act.
The R&D Tax Credit: IRC §41
The research and development tax credit, sometimes called the research credit, is governed by IRC §41 and reduces your federal tax liability directly, dollar for dollar, rather than reducing the income you are taxed on.
Not every research expense automatically qualifies for the credit; to claim it, the underlying activity must satisfy all four parts of the four-part test as defined in Treasure Regulation Section 1.41-4:
• Permitted Purpose: The activity must be intended to develop or improve the functionality, performance, reliability, or quality of a business component.
• Technological in Nature: The work must rely on engineering, physical or biological science, or computer science principles.
• Technical Uncertainty: The activity must be undertaken to discover information intended to eliminate uncertainty about the capability, method, or appropriate design of the business component.
• Process of Experimentation: Your team must have a process that evaluates alternatives through modeling, simulation, systematic trial and error, or other methods to eliminate uncertainty.
Expenses that support qualifying activity are Qualified Research Expenses (QREs) and fall into four categories:
- Qualified wages paid to employees who directly perform, directly supervise, or directly support the research.
- Qualified supplies consumed in the research (not capital equipment or land).
- Qualified contract research payments to outside parties who perform research on the company's behalf.
- Qualified rental or lease costs of computers used in the research.
Businesses calculate and claim the credit on IRS Form 6765, using either the regular credit method or the Alternative Simplified Credit method.
The R&D Deduction: IRC §174A (Domestic) and §174 (Foreign)
The R&D deduction lives in a different part of the code than the credit. The current law splits it into two sections dependent on where the research is performed. For tax years beginning after December 31, 2024, domestic research and experimental expenditures are governed by the newly enacted IRC §174A, and the deduction simply reduces the amount of income that gets taxed in the first place, the same way another ordinary business expense does.
§174A also defines its covered expenses more broadly than §41 and does not require the four-part test, instead carrying forward the longstanding standard from Treas. Reg. §1.174-2: costs qualify if they are incurred in connection with the taxpayer's trade or business and represent research and development costs in the experimental or laboratory sense, meaning the activity is intended to discover information that would eliminate uncertainty about the development or improvement of a product, including its capability, its method of development, or its appropriate design.
The mechanics of this specific deduction changed in recent years; under the Tax Cuts and Jobs Act, businesses lost the option of deducting domestic research expenditures immediately starting with tax years after December 31, 2021. Instead, they were required to capitalize those costs and amortize them over five years for domestic research, or fifteen years for research performed outside the U.S., which was detrimental to research-heavy companies utilizing the deduction.
Under current law, IRC Section 174A allows businesses to deduct qualifying domestic research and experimental expenditures in the year paid or incurred, subject to the rules and elections the statute provides, including an available election under Section 174A(c) to instead capitalize and amortize domestic expenditures over a period of at least 60 months. Research performed outside the United States is still required to be capitalized and amortized over fifteen years under Section 174.
The Core Differences, Side by Side
By the numbers: $100,000 in Credits vs. Deductions
Here’s what $100,000 in credits looks like versus a $100,000 deduction:
Note: the table compares a $100,000 credit to a $100,000 deduction. The R&D credit itself is calculated as a percentage of qualified research expenses, so your credit won't equal your R&D spend.
Can a Business Claim Both?
In some cases, yes, as the same domestic research spending can generate a deduction and a credit; a wage or supply cost that qualifies as a QRE under §41 will often also qualify as a QRE under §174A. The tax code does not, however, allow a business to get the full, uncoordinated benefit of both on the same dollar of spending.
Under IRC §280C, a business that does not make the reduced credit election is generally required to reduce its domestic research and experimental expenditures under §174A by the amount of the research credit claimed, so that the same expense is not fully deducted and fully credited at the same time. Many businesses instead make the reduced credit election under Section 280C(c)(3), which lowers the credit amount using the maximum corporate tax rate but allows the business to keep the full deduction. This election generally must be made on a timely filed return, including extensions, and generally cannot be added later on an amended return, which is one reason the choice is worth discussing with a tax professional before the original filing deadline rather than after. Certain eligible small businesses and prior tax years may be subject to separate transition rules, so this is an area where current-year facts matter.
Why the Distinction Matters
A business that treats the credit and deduction as the same risks either under-claiming a benefit it may be entitled to, or filing a return that does not reflect the proper adjustments. This is something a qualified consultant is trained to do, and why it’s imperative to work with someone who has a deep understanding of the credit and the deduction.
Frequently Asked Questions
Is the R&D tax benefit a credit or deduction?
It can be both. The R&D tax credit under IRC Section 41 and the domestic research deduction under IRC Section 174A are separate tax benefits, and qualifying research spending can potentially generate both, subject to the coordination rules under Section 280C.
Can I claim the R&D tax credit and deduct the same research expenses?
No, at least not in full. Under §280C, a business claiming the full R&D credit must reduce its research deduction by the credit amount, unless it makes the reduced credit election under §280C(c)(3), which lowers the credit but preserves the full deduction.
Do all research expenses qualify for both the credit and the deduction?
Not necessarily. §41 and §174A use different qualification rules. §41 requires research to satisfy the statutory four-part test, while §174A governs domestic research and experimental expenditures more broadly, under its own rules. Some costs may qualify for the deduction without qualifying for the credit.
Does it matter where the research is performed?
Yes. Domestic research and experimental expenditures are deductible immediately under §174A, the current law's default treatment. Research performed outside the United States must be capitalized and amortized over fifteen years under §174. The research credit also contains a domestic-research requirement, so location can affect credit eligibility too.
What RK Partners Can Do for Your Business

R&D Tax Credits for Timberland and Forest Management Companies
Timberland owners and forest management companies often don’t recognize that they may qualify for R&D tax credits, but many of them are already performing research and development activities when improving operations.
R&D Tax Credits for Postharvest Processors
Many agricultural operations don’t think that they’d qualify for R&D tax credits, and that’s not just reserved for farmers. It applies to other essential agriculture operations, such as grain elevator managers and postharvest processors.
