R&D Tax Credits
What Is the R&D Tax Credit?
The Research & Development (R&D) Tax Credit (IRC Section 41) is a federal incentive designed to encourage innovation and domestic research activities in the United States.
Despite its name, the R&D Tax Credit does not require lab coats, revolutionary scientific breakthroughs, or patent development. Many companies qualify through everyday engineering, software development, product improvement, and process optimization activities—but fail to claim the credit because eligibility rules are misunderstood or poorly documented.
When claimed properly, the R&D Tax Credit provides a dollar‑for‑dollar reduction in tax liability and, in some cases, payroll tax offsets.
Who Qualifies for the R&D Tax Credit?
The common assumption is that activities must be performed in a research lab to qualify for the R&D Tax Credit. However, the reality is that the threshold is much lower. Your research activities must simply pass the IRS Four-Part Test.
If your company meets the following criteria, it is highly likely that you engage in qualified activities that generate a credit.
Technological
in Nature
The activity must rely on principles of hard sciences, such as physics, engineering, computer science, chemistry, or biology.
Technological Uncertainty
At the outset of the project, there must be uncertainty regarding capability, methodology, or design.
Process of Experimentation
Solution alternatives must be theoretically or physically evaluated through modeling, prototyping, testing, or iterative development.
Permitted
Purpose
The objective must be to improve the fit, form, function, performance, reliability, or quality of a product, process, or software.
Indicators of Qualified Research
- Degreed engineers or scientists on staff
- Manufacturing industry operations
- Patentable products or production methods
- New or continuous improvements to products and/or processes
- Industries where prototyping is common
- Government R&D projects, from programs such as: SBIR, STTR
- Continuous quality improvement efforts
- Simple products manufactured in highly automated systems
- High warranty costs due to improper product/process design
- Software development using new algorithms, techniques or architectures
- Outsourced research and/or testing
Eligible Expenses
Wages
Wages Paid to Employees in Direct Conduct, Direct Supervision, or Direct Support of Qualified Research Activities
Supplies
Materials used in the conduct of qualified research including prototypes, consumables, and tooling
Contract Research
Expenses paid to outside contractors for conducting research activities on behalf the company
Audit Defense
Hull & Knarr has decades of experience defending R&D Tax Credit claims in front of the IRS and state taxing authorities. Because of our due diligence and expertise with the tax code, regulations, and case law, we use a reliable and strategic approach to defending credits under audit.
Documentation the IRS Expects
The IRS does not require perfection, but it does require credibility and consistency. Strong documentation includes:
- Technical narratives tied to projects
- Employee role and activity mapping
- Contemporaneous project records
- Interview summaries
- Logical wage allocation methodology
Claims relying entirely on generalized estimates or accounting‑only calculations are far more likely to face disallowance.
Audit Risk and Defensibility
The IRS uses its own degreed engineers to review and select R&D Tax Credit claims due to:
- Large credits relative to revenue
- Repeated retroactive claims
- Generic narratives
- Inconsistent methodologies year over year
An engineering‑based study, supported by detailed documentation and defendable logic, significantly reduces audit exposure and improves sustainability.
Hull & Knarr Experience
Hull & Knarr uses engineering‑based methodologies supported by CPA review, designed to maximize defensibility, not just credit size. We document your claim as if it will be reviewed. And if you are audited, we will be there to defend you.

R&D Tax Credits Frequently Asked Questions
The R&D tax credit (IRC Section 41) is a permanent federal incentive that provides a dollar-for-dollar reduction in income tax for businesses that create or improve products, processes, formulas, techniques, or software. It equals 6% to 12% of qualifying research expenses, including employee wages, supplies, and contract research costs.
Any business that develops or improves products, processes, formulas, techniques, or software may qualify. This includes companies in software, manufacturing, engineering, food and beverage, aerospace, agriculture, and many other industries. You do not need a laboratory or scientists. The activity must simply pass the IRS Four-Part Test, and the qualifying activities must take place in the US or its territories.
The credit ranges from 6% to 12% of qualified research expenses. The exact amount depends on your wages, supplies, and contract research costs, and whether the qualified activities happened in a State where a State R&D Tax Credit is also available. You can get a quick estimate of your R&D Tax Credits by using our online R&D Tax Credit calculator.
Yes. Because the R&D Tax Credit is filled with the business’ tax returns, you can generally claim the R&D Tax Credit up to three years from the date the original return was filed.
Yes. In general, companies that meet the following qualifications may use the credit to offset payroll taxes instead of income tax:
- Gross Receipts: Have less than $5 million in annual gross receipts for the current tax year.
- Age: Have no more than 5 years of gross receipts (meaning you cannot have had revenue more than 5 years ago).
Not necessarily. Even in years when the business generates a tax loss, the company can still continue to claim the R&D Tax Credit. It may still benefit immediately through payroll tax offsets. Or the Federal Tax Credits can be carried forward for up to 20 years. Carryforward for States R&D Tax Credits vary by state.
No. Claiming R&D credits does not automatically trigger an audit. The IRS has a dedicated review process for R&D Tax Credit claims that is separate from general audits. Well-documented claims with the Four-Part Test properly substantiated face minimal scrutiny. Hull & Knarr provides free audit defense on every engagement.
The OBBBA retroactively repealed the requirement in Section 174 to amortize all domestic R&D expenses for tax years 2022 through 2024. Businesses that stopped claiming credits during those years can now amend their returns and receive refunds. Final filing deadlines are quickly approaching. Get in touch with us to see if your business is eligible.
Yes. Hull & Knarr works with your CPA and does not replace them. We work collaboratively with accounting firms to ensure proper documentation, compliance, filing, and the maximum benefit is achieved for their clients.
