What is R&D Tax Credit?

The research and development (R&D) tax credit results in a dollar-for-dollar reduction in a company’s tax liability for certain domestic expenses. Qualifying expenditures generally include:

  • Design

  • Development

  • Improvement of products

  • Processes

  • Techniques

  • Formulas

  • Software

Further details on the R&D tax credit are outlined under Section 41 of the Internal Revenue Code.

Universal Access to R&D Tax Credits

R&D tax credits are available to all organizations that engage in certain activities to develop:

  • New or improved products

  • Processes

  • Software

  • Techniques

  • Formulas

  • Inventions

This accessibility is partly due to the Protecting Americans from Tax Hikes (PATH) Act of 2015, which expanded the ability of many small to mid-sized businesses to utilize the R&D credit.

Documenting Qualifying Expenses for IRC Section 41 Compliance

Businesses can claim the R&D Credit by filing IRS Form 6765, Credit for Increasing Research Activities. As part of the process, they must identify qualifying expenses and provide adequate documentation that demonstrates how these costs meet the requirements under Internal Revenue Code Section 41. Financial records, business records, oral testimony, and technical documents may be used for this purpose.

Does Your Startup Qualify for R&D Tax Credit?

The R&D Tax Credit is not limited to large corporations or high-tech firms—it’s available to any U.S.-based business that incurs expenses while trying to develop or improve a product, process, or technology. If your company is solving technical problems or experimenting with new approaches, you might qualify.

To determine eligibility, the IRS uses a four-part test:

1. Elimination of Uncertainty

Your research must aim to eliminate uncertainty about the development or improvement of a product or process. This means you were unsure how to achieve the desired result and needed to resolve technical questions, not just change a design or appearance.

2. Process of Experimentation

Your work must involve a process of testing, modeling, or trial and error to find a solution. If your team uses prototypes, simulations, or systematic evaluation to explore different options, your project may qualify.

3. Technological

The activities must rely on the hard sciences, such as engineering, computer science, chemistry, or physics, not marketing or aesthetics.

4. Qualified Purpose

The objective must be to create or improve functionality, reliability, performance, or quality, rather than simply customizing something for a client or duplicating existing work. Nevertheless, certain activities are excluded from qualifying. These include:

  • Research conducted after a product goes into commercial production

  • Adapting existing products for specific customer needs

  • Duplicating existing products or processes

  • Surveys, market studies, or consumer testing

  • Research in the arts, humanities, or social sciences

  • Work conducted outside the U.S.

  • Government-funded research

  • Certain internal-use software

Special Rules for Startups and New Businesses

The traditional R&D tax credit reduces your income tax bill. Still, for early-stage companies with little or no taxable income, there’s a powerful alternative: the payroll tax offset, introduced by the PATH Act of 2015.

Eligibility and Benefits

Startups can apply up to $250,000 of the R&D credit each year to offset their employer payroll tax (FICA) for up to five years, giving them much-needed liquidity to reinvest in growth, even if they’re not profitable yet. To qualify for this option, a business must:

  • Have gross receipts for five years or fewer

  • Earn less than $5 million in gross receipts in the credit year

  • You must make this election on your originally filed tax return—you cannot retroactively apply the credit to payroll taxes with an amended return.

Eligible small businesses (with average gross receipts under $50 million over the prior three years and not publicly traded) can also use the R&D credit to offset the Alternative Minimum Tax (AMT).

Broad Applicability of the R&D Credit Across U.S. Industries

Suppose you’re investing in innovation and development in the U.S.. In that case, chances are you qualify for this credit, whether you’re a manufacturing firm testing new materials, a SaaS startup building out product features, or an agtech company developing sensor technology. The key is proper documentation, thoughtful tax planning, and accurate credit filing.

R&D Tax Credit Calculation Options

Taxpayers can choose from two calculation methods to calculate the R&D tax credit:

  • Regular research calculation method (RRC)

  • Alternative simplified credit method (ASC)

The calculation you select determines how much credit you will receive, making it crucial to choose correctly to maximize the credit. 

Regular Research Calculation Method

The regular research calculation method is 20% of all qualifying expenditures for the current year exceeding a specific base amount. Businesses can calculate the base amount by multiplying the fixed-base percentage by the average gross receipts from the previous four years. 

A Step-by-Step Guide

For example, if a company has qualifying research expenses (QREs) for the past four years:

  • Divide the aggregate QREs by the aggregate gross receipts over the same period to determine the fixed-base percentage.

  • Take the lesser of the fixed-base percentage calculated or 16%.

  • Multiply the fixed-base percentage by the average annual gross receipts from the previous four years to determine the base amount.

  • Take the greater of the base amount calculated or 50% of the current year’s QREs.

  • Subtract the minimum base amount from the current year’s QREs. 

  • Multiply the result by 20%.

Organizations that have not claimed the credit in the past or do not have at least four years of expenditure data will find it challenging to use this method. Recently established companies will find the ASC tax credit calculation method easier. 

Alternative Simplified Credit Method

The alternative simplified credit method is a more straightforward calculation method that makes the R&D tax credit more accessible to a broader range of businesses. Nevertheless, the ASC calculation typically yields a lower tax credit percentage. The ASC is calculated by: 

  • Determine the average of the company’s QREs for the past three years. 

  • Multiply the average by 50%. 

  • Subtract that number from the current year’s expenses. 

  • Multiply that number by 14%.

If an organization does not have QREs for any of the past three years, the tax savings equal 6% of QREs for the current year.

R&D Credit for Payroll Expenses

Companies can use either calculation method to offset up to $250,000 in employer social security payroll expenses. Nonetheless, only certain businesses can qualify. A qualifying small business must have less than $5 million and five years or less in gross receipts for the year it claims R&D credit. 

Electing Reduced Credit 

For both methods, there is also an option to take a reduced tax credit by electing a 280(c) form. Electing to accept a reduced credit amount can be helpful if taking the full amount raises your taxable income to a higher tax bracket. Taking the entire credit amount can subject companies to an increased tax rate as they are receiving additional income. 

Optimizing Credit for Corporate Structures

For example, S corporations on the verge of entering a higher tax bracket may want to receive a reduced credit to avoid being taxed at a higher rate. On the other hand, C-corporations have a consistent tax rate and should not opt for a reduced credit. 

Leveraging State-Level R&D Credits

In addition to the federal R&D tax credit, many states offer state-level credits that businesses can receive. To maximize tax savings, it is crucial to become familiar with your state-level R&D tax credit regulations.

How to Calculate the R&D Tax Credit Using the Traditional Method

1. Start With Your Qualified Research Expenses for the Year

To calculate your R&D tax credit using the traditional method, begin by totalling your Qualified Research Expenses for the tax year you’re calculating the credit. These expenses typically include:

  • Wages

  • Supplies

  • Contract research

  • Other costs associated with developing or improving:

  • Products

  • Processes

  • Software 

2. Calculate the Fixed-Base Percentage

Next, take your total QREs from the base period—typically the 1984–1988 tax years or the first five years of qualified research if you’re a newer company—and divide them by your total gross receipts for the same period. This gives you the fixed-base percentage. The fixed-base percentage cannot exceed 16 percent. 

3. Determine Your Base Amount

Multiply your fixed-base percentage by the average annual gross receipts from the four tax years preceding the current tax year. The result is your base amount. Nevertheless, there’s a lower limit: your base amount must be at least 50 percent of your current year’s QREs. If the calculated base amount is less than this, increase it to meet the 50 percent floor. 

4. Calculate Your Credit

Subtract the base amount from your current year QREs. Then multiply the difference by 20 percent. This gives you the gross R&D tax credit under the traditional method.

Example

Let’s say:

  • Current Year QREs: $1,000,000

  • QREs during Base Period: $400,000

  • Gross Receipts during Base Period: $5,000,000

  • Average Gross Receipts for Prior 4 Years: $3,000,000

Applying the Fixed-Base Percentage Method

  • Fixed-base percentage = $400,000 / $5,000,000 = 8%

  • Base amount = 8% × $3,000,000 = $240,000

Minimum base amount = 50% × $1,000,000 = $500,000

Use the greater of the two: $500,000

  • $1,000,000 – $500,000 = $500,000

  • 20% × $500,000 = $100,000 tax credit

Traditional R&D Credit vs. ASC

While the traditional method can yield a generous credit, it involves more complex historical data and base period analysis compared to the Alternative Simplified Credit (ASC) method, which many companies prefer due to its simplicity. Still, for businesses with good historical records and consistently low base period QREs relative to current spending, the traditional method can result in a larger credit.
