Your Essential Guide to Qualified Research Expenses: IRS Rules Made Simple
Business owners often picture scientists in white lab coats working in high-tech labs when they think about qualified research expenses. This misconception stops many businesses from claiming R&D tax credits they deserve.
The IRS defines qualified research expenses (QREs) as “the sum of in-house research expenses and contract research expenses”. These expenses are the foundations of the research and development tax credit – one of the most important domestic tax credits in current tax law. Many businesses find it hard to identify which activities and costs qualify for this valuable credit.
The story begins in 1981 when Congress created this nonrefundable tax credit. They wanted companies to do more research and help them handle the high costs of research programs. The rules about what expenses qualify for the R&D tax credit can be tricky to grasp. QREs cover more costs than you might think – from employee wages for qualified services to supplies used in research work.
This piece breaks down the IRS rules about qualified research expenses credit. You’ll learn everything needed to check if your business activities fit the requirements. On top of that, it shows you how to document these expenses to maximize your tax benefits.
What are Qualified Research Expenses (QREs)?

Qualified research expenses (QREs) are specific costs that businesses can include to calculate their research and development tax credit. You need to know what counts as a QRE to maximize tax benefits and stay compliant with IRS regulations.
Definition under IRS Section 41
IRS Section 41 defines qualified research expenses as “the sum of in-house research expenses and contract research expenses”. These definitions are the foundations for determining eligible costs.
In-house research expenses have three main components:
- Wages paid to employees performing qualified services
- Supplies used directly in research activities
- Computer rental costs related to qualified research
In stark comparison to this, contract research expenses typically include 65% of amounts paid to outside vendors or contractors who perform qualified research for you. This percentage goes up to 75% for payments to qualified research consortiums. Small businesses, universities, or federal laboratories can claim up to 100% for energy research.
Why QREs matter for R&D tax credit
QREs are the foundations for R&D tax credit calculations. Businesses can offset their tax liability based on qualifying research activities. This 40-year old credit serves as a key financial incentive that encourages state-of-the-art solutions.
The credit’s value comes from its wide reach in any industry. Many people think qualifying research happens only in laboratories. However, activities from new product development to manufacturing process improvements can qualify if they meet specific criteria.
Overview of the 4-part test for qualified research
Research activities must pass these four IRS tests to qualify as a QRE:
- Section 174 Test – Expenses must be treated as research and experimental expenditures
- Discovering Technological Information Test – Research must be technological in nature, based on principles of physical/biological sciences, engineering, or computer science
- Business Component Test – Research must relate to a new or improved business component (product, process, software, technique, formula, or invention)
- Process of Experimentation Test – 80% or more activities must involve a process of experimentation for a qualified purpose
This test ensures that qualifying research tackles real technological uncertainty through systematic experimentation.
Types of Qualified Research Expenses

Understanding QRE categories helps businesses calculate their potential R&D tax credit accurately. The IRS recognizes four main categories of QREs, and each one comes with its own qualification requirements.
Wages for qualified services
Employee compensation for qualified services makes up the largest portion for most businesses. These services come in three forms: direct research work, research supervision, and direct support of qualified research.
Employees who dedicate most of their time to research get a vital benefit: their wages can be claimed 100% if “substantially all” (at least 80%) of their work involves qualified research. The qualified portion of wages applies only to direct research activities for other cases.
Supplies used in research
Research supplies that qualify must be tangible materials used directly in the research process. The IRS says supplies are non-depreciable tangible property used in qualified research. Raw materials for prototypes, testing chemicals, and electronic components for trial models are good examples.
Land, land improvements, and depreciable property don’t count as supplies. Supply costs usually make up a small part of total QREs. The IRS might take a closer look if supply costs are unusually high compared to other expenses.
Contract research expenses
Businesses can claim 65% of payments as QREs when they hire outside researchers. This number goes up to 75% for qualified research consortiums. Small businesses, universities, or federal laboratories doing energy research might qualify for up to 100%.
Three key requirements need to be met: you must have an agreement before starting the research, keep the rights to research results, and bear the financial risk whatever the outcome.
Computer rental for research purposes
The last category has costs for computer usage in qualified research. This covers cloud computing and server rental expenses tied to R&D activities. These expenses qualify only if someone else owns the computer, it’s located off-site, and you’re not its main user.
IRS Rules and Compliance Requirements
Businesses need to pay close attention to IRS rules about qualified research expenses. Many organizations miss important details that can affect their R&D credit claims.
The ‘80% Rule’ for Wages
The IRS has a vital “substantially all” test – employees must spend 80% or more of their time on qualified research activities. Meeting this threshold means 100% of the employee’s wages become eligible as research expenses. The IRS allows only the direct research portion of wages for employees who fall below this threshold.
How the IRS Views Supervision and Support
The IRS considers immediate first-line management of qualified research as direct supervision. Most senior managers don’t qualify unless they actively participate in research. Direct support includes services that help researchers or their immediate supervisors.
Eligible Expenses for R&D Tax Credit
The IRS only accepts expenses from research done in the United States. These include:
- Wages paid for qualified research work
- Research supplies (non-depreciable tangible items)
- 65% of contract research payments made to outside parties
- Research-related computer rental costs
Expenses That Don’t Qualify
The IRS excludes these expenses:
- Travel, meals, entertainment
- Researchers’ phone expenses
- General administrative work
- Professional memberships or licensing fees
- Equipment rental and depreciation costs
Documentation and Substantiation Best Practices

Documentation is the life-blood of defending your qualified research expenses during an IRS examination. You must validate your R&D credit claims because the burden of proof falls on you as the taxpayer.
Time tracking and payroll records
Timekeeping systems are the foundations of R&D credit claims. These records show a clear connection between employees and their qualified research activities. Contemporaneous documentation must exist for wages to qualify instead of estimates made later. The IRS accepts payroll records, employee job descriptions, performance evaluations, and calendars as primary evidence. Time tracking apps are a great way to get detailed reports that support your claim.
Contracts and statements of work
Treasury Regulation section 1.41-2(e) defines a three-part test for contract research expenses. The agreement must exist before research starts. It needs to specify research done on your behalf and require payment whatever the outcome. Keeping copies of all research contracts is significant. The IRS recommends you provide a list of all contracts with claimed expenses for each during audits.
Using estimates and the Cohan rule
Precise tracking works best, but the Cohan rule (Cohan v. Commissioner) lets taxpayers use reasonable estimates when actual records don’t exist but have a factual basis. The rule has limits though. It applies only to determine the amount of allowable deduction, not to prove the existence of the expense. Courts don’t have to apply this rule without enough evidence.
Lessons from recent tax court cases
Recent court decisions reveal documentation mistakes clearly. The court in Moore rejected portions of claimed wages because records failed to separate qualified research time from general product development work, despite testimony from company leaders. The Little Sandy Coal case showed that oral testimony alone doesn’t work without supporting documentation. These cases prove that while estimates can help, real-time records backed by credible supporting evidence remain vital for successful claims.
Conclusion
R&D tax credits start with understanding qualified research expenses. Many companies think these credits only apply to laboratory settings or scientific work. But as we’ve shown in this piece, qualified research expenses cover many activities in industries of all types.
The IRS four-part test gives you a clear framework to determine which activities qualify. Your business should review its operations against these criteria: Section 174 requirements, technological information discovery, business component relevance, and process of experimentation. Meeting all four parts helps you tap into valuable tax benefits that can reduce your tax burden substantially.
Wages make up the largest portion of qualifying expenses. Supplies, contract research, and computer rental costs also matter. The “substantially all” rule needs careful attention – if 80% of an employee’s work involves qualified research, their entire wages could qualify.
Documentation is the life-blood of successful R&D credit claims. Contemporaneous records provide the best defense during IRS examinations. Time tracking, detailed contracts, and proven expenditures build a solid foundation for your claim. While estimates might be enough under the Cohan rule, recent tax court cases show that proper documentation proves your success.
The R&D tax credit remains one of the most valuable tax benefits accessible to innovative businesses today. Congress designed it to encourage research and development that stimulates economic growth. You can claim what you rightfully deserve while staying compliant with IRS regulations by understanding qualifying expenses and maintaining proper documentation.
Don’t assume your business doesn’t qualify. Take time to get into your activities against these criteria. Note that qualified research expenses go nowhere near just traditional laboratory work—your business might qualify without even knowing it.
