What is RD Tax Credit?

Understanding the RD Tax Credit can seem like decoding a complex puzzle. But don’t worry, it’s simpler than it sounds. Let’s break it down.


At its core, the RD (Research and Development) Tax Credit is a government incentive designed to reward businesses for investing in innovation. This could be new products, processes, or software development. Essentially, it’s the government’s way of saying, “Keep innovating, we’ve got your back.”

Section 41

The magic happens under Section 41 of the Internal Revenue Code (IRC). This section is the rulebook for the RD Tax Credit. It outlines what counts as qualifying research activities (QRAs) and expenses (QREs), and how businesses can calculate their credits. Think of it as the blueprint for claiming your innovation rewards.


In 2015, the Protecting Americans from Tax Hikes (PATH) Act was a game-changer for the RD Tax Credit. Why? Because it made the credit permanent. That’s right, businesses can now count on this benefit year after year. Plus, the PATH Act opened the doors for more businesses, especially startups and small businesses, to claim the credit against payroll taxes. This was a big win for innovation.

So, how does RD tax credit work in practice? Imagine your business spends $100,000 on qualifying research activities. Under the RD Tax Credit, you could receive a dollar-for-dollar tax liability reduction, plus an additional percentage back. This can significantly lower your tax bill or even increase your refund, freeing up more cash for further innovation.

In summary, the RD Tax Credit is a powerful tool for businesses of all sizes to support their innovation efforts. It’s not just for the big players in tech or pharmaceuticals; small businesses and startups are also eligible. With the help of Section 41 and the PATH Act, the RD Tax Credit is easier to claim and more beneficial than ever.

As we move into the next section, keep in mind that maximizing your RD Tax Credit benefits requires understanding the qualifying criteria and how to document your innovative activities properly. Let’s dive deeper into who qualifies for this lucrative credit and how your business can claim it.

Who Qualifies for RD Tax Credits?

When it comes to the Research and Development (RD) Tax Credit, many business owners mistakenly believe it’s out of their reach. However, a wide range of businesses, from fledgling startups to established small-to-midsize businesses across various industries, can qualify. Let’s break it down:

Small-to-Midsize Businesses

If you’re running a small or midsize business and investing in new products, processes, or software, the RD Tax Credit could be within your grasp. Dave Tilstone, Executive Director of Business Development at bavius technologie, emphasizes, “The truth is that qualifying for the credit is not complex. Your company simply needs to be working to improve a product or process here in the U.S.” This means if your business is actively engaging in activities to enhance its offerings or operations, it could potentially benefit from this credit.


Startups, often at the forefront of innovation, have a unique advantage when it comes to the RD Tax Credit. Even if your startup isn’t profitable yet, you can still claim the credit against payroll taxes, up to $250,000 annually for up to five years. This provision is designed to support startups in their critical growth phase, making the RD Tax Credit a valuable tool for new businesses focused on research and development.


The scope of industries that qualify for the RD Tax Credit is broad and varied. It’s not just tech giants or pharmaceutical companies that can claim this credit. Businesses across manufacturing, software, agriculture, and architecture, among others, can qualify. The key is engaging in activities aimed at improving products, processes, or software. Whether you’re developing a new agricultural technique, designing innovative architectural solutions, or enhancing manufacturing processes, your business could be eligible.

Examples of Qualifying Activities:

  • Developing new or improved products: This includes any work aimed at enhancing the quality, functionality, or reliability of a product.
  • Software development: Designing new software solutions or improving existing ones can qualify.
  • Process improvement: Activities aimed at making manufacturing or other business processes more efficient, cost-effective, or sustainable.
  • Technical problem-solving: Engaging in research to overcome technical challenges or uncertainties in your field.

Key Takeaway:

Don’t count your business out when it comes to the RD Tax Credit. With a broad definition of qualifying research activities and a wide range of eligible industries, many businesses stand to benefit. Whether you’re a small local manufacturer or a tech startup, if you’re investing in innovation, it’s worth exploring whether the RD Tax Credit can help support your growth and enhance your bottom line.

In the next section, we’ll guide you through the process of claiming the RD Tax Credits, including the necessary documentation and how to navigate IRS Form 6765. Stay tuned to unlock the potential savings and benefits for your business.

How to Claim RD Tax Credits

Claiming the Research and Development (RD) Tax Credit doesn’t have to be a daunting task. Let’s break it down into simple steps, focusing on IRS Form 6765, the documentation you’ll need, and understanding what qualifies as an expense.

IRS Form 6765

Your journey to claiming RD tax credits starts with IRS Form 6765, also known as the Credit for Increasing Research Activities. This form is essential for any business looking to claim the RD tax credit. Here’s a quick overview:

  • Section A is for those claiming the regular credit.
  • Section B details the alternative simplified credit.
  • Section D is specifically for qualified small businesses aiming to offset payroll taxes.

The IRS recommends calculating your credit using both the regular and simplified methods to see which one offers the best benefit for your business.

Documentation: Your Proof

The IRS operates on a principle of “trust, but verify.” This means you’ll need to provide solid evidence of your RD activities. Here’s what to keep on hand:

  • Payroll records for employees directly involved in RD.
  • Receipts and invoices for supplies and equipment used in RD activities.
  • Contracts with third parties who conducted RD on your behalf.
  • Technical documents, such as blueprints, patents, and progress reports, that detail your research.

The more detailed your documentation, the smoother the process will be. The burden of proof is on you, so it’s better to be over-prepared.

Qualifying Expenses: What Counts?

Not all expenses related to RD will qualify for the tax credit. Here’s a rundown of what does:

  • Wages for employees directly involved in or supervising RD activities.
  • Supplies used directly in research (this does not include capital items or land).
  • Contractor expenses for third-party RD services, which are limited to 65% of the total payment.
  • Cloud computing costs for software used exclusively in RD.

Expenses must be tied to projects that meet the four-part test outlined by the IRS, focusing on new or improved functionality, performance, reliability, or quality.

Navigating the Process

  1. Gather Your Documentation: Start by collecting all relevant financial records, contracts, and technical documents.
  2. Fill Out Form 6765: Carefully complete each section, ensuring you calculate both the regular and simplified credits to determine which is more beneficial.
  3. Identify Qualifying Expenses: Review your expenses to ensure they meet the IRS criteria for RD activities.
  4. Submit With Your Tax Return: Attach Form 6765 to your business’s federal income tax return and submit it by the tax filing deadline.

By following these steps and ensuring you have all the necessary information, claiming the RD tax credit becomes a manageable task. This not only helps in claiming a valuable tax credit but also supports your business’s innovation efforts.

In the next section, we’ll explore how to calculate your RD tax credit, focusing on the traditional method, the Alternative Simplified Credit (ASC), and understanding Qualified Research Expenses (QREs). Stay tuned for insights that could significantly impact your business’s financial health.

Calculating Your RD Tax Credit

Calculating your RD tax credit might seem like a daunting task at first. However, breaking it down into simpler components can make it more manageable. Let’s dive into the traditional method, the Alternative Simplified Credit (ASC), the fixed-base percentage, and how to identify Qualified Research Expenses (QREs).

Traditional Method

The traditional method requires you to look at your past. Specifically, it involves comparing your current year’s research expenses to those from a base period in the past. Here’s a simple breakdown:

  1. Identify your base years, usually a set period in the 1980s or 1990s, depending on when your company started its R&D activities.
  2. Calculate the average of your R&D expenses during these base years.
  3. Determine the fixed-base percentage by dividing your historical R&D expenses by your total sales during the base period.
  4. Apply this percentage to your current year’s total sales to find your base amount.
  5. Any current R&D expenses over this base amount could qualify for the credit.

This method can be more beneficial for companies with a long history of R&D but requires digging into old records.

Alternative Simplified Credit (ASC)

The ASC method is a more straightforward approach, especially for newer companies or those without detailed historical records. Here’s how it works:

  1. Calculate your total R&D expenses for the last three years.
  2. Find the average of these expenses.
  3. Multiply this average by 50% to get your base amount.
  4. Subtract this base from your current year’s R&D expenses to find the amount eligible for the credit.
  5. Apply a 14% credit rate to this amount to calculate your credit.

ASC Calculation Process - how does rd tax credit work

This method is generally easier and can be more favorable for companies with increasing R&D expenditures.

Fixed-Base Percentage

The fixed-base percentage is crucial for both the traditional and ASC methods. It’s essentially a ratio that compares your past R&D expenses to your total sales, showing how much of your sales were reinvested into R&D. This percentage helps to establish a benchmark for what constitutes an increase in R&D spending.

Qualified Research Expenses (QREs)

Identifying what expenses qualify is fundamental to calculating your credit accurately. QREs typically include:

  • Wages for employees directly involved in R&D activities.
  • Supplies used in the R&D process.
  • Contract research expenses, which are payments to third parties for conducting R&D on your behalf (limited to 65% of the total payment).
  • Cloud computing costs for software used directly in R&D activities.

Not all R&D expenses qualify. For example, costs related to market research, quality control, and research done outside the United States do not qualify.

In Summary:

Calculating your RD tax credit doesn’t have to be complicated. Whether you use the traditional method or the ASC, the key is understanding your company’s R&D expenses and how they align with IRS guidelines. Keep detailed records of your R&D activities and consult with a tax professional if you’re unsure about qualifying expenses. This careful approach not only ensures you claim a valuable tax credit but also supports your business’s innovation efforts.

In the next section, we’ll look at how you can maximize your RD tax credit benefits, including strategies for offsetting payroll taxes, carrying forward unused credits, and making retroactive claims. Stay tuned for insights that could significantly impact your business’s financial health.

Maximizing Your RD Tax Credit Benefits

Maximizing the benefits of your RD tax credit is like finding hidden treasure in your own backyard. It’s there, waiting to be discovered, and can bring substantial financial rewards to your business. Let’s dig into how you can unearth these benefits.

Payroll Offset: A Golden Opportunity for Startups

If you’re a startup, the payroll offset is your best friend. Here’s why:

  • Eligibility: Startups with less than $5 million in gross receipts and less than five years of revenue can benefit.
  • Savings: You can offset up to $250,000 of your payroll taxes annually for up to five years. That’s a potential of $1.25 million in savings!

This means, even if you’re not yet profitable, you can still benefit from your RD efforts. It’s an immediate cash injection that can support further innovation or ease the financial pressures of growing your business.

Carry Forward: Don’t Leave Money on the Table

What if you can’t use all of your RD tax credit in the current year? No problem. You can carry forward unused credits for up to 20 years. This is particularly useful for businesses that are:

  • In their early stages and not yet profitable
  • Experiencing a down year

By carrying forward your credits, you ensure that your RD investments continue to pay dividends well into the future.

Retroactive Claims: Looking Back to Move Forward

Did you know you can amend past tax returns to claim RD tax credits you might have missed? Here’s how it works:

  • Look Back: You can generally amend tax returns for the last three open tax years.
  • Potential Refund: If you find unclaimed credits, filing an amended return can result in a substantial tax refund.

This is an often-overlooked strategy that can provide a significant cash infusion. It’s like finding money you didn’t know you had!

Frequently Asked Questions about RD Tax Credit

When diving into RD tax credits, several common questions often arise. These questions are crucial for businesses looking to maximize their benefits from RD tax credits. Let’s break down these questions to give you a clearer understanding of how does rd tax credit work.

How much can you save with RD tax credit?

The amount you can save with an RD tax credit can be significant, but it varies depending on several factors such as the amount spent on qualifying research and development activities, the size of your business, and your tax liability. On average, businesses can expect to see a credit rate of 6% to 8% of their eligible expenses. For startups, there’s a special provision allowing them to claim up to $250,000 against payroll taxes annually for up to five years. This means, if you’re eligible, the RD tax credit can substantially reduce your tax liability or even improve your cash flow by reducing the amount you owe in payroll taxes.

What are the four criteria for RD tax credit?

To qualify for the RD tax credit, your research activities must meet four specific criteria set by the IRS:

  1. Permitted Purpose: The activity must aim to create a new or improved product or process that results in increased performance, reliability, or quality.
  2. Technological in Nature: The research must rely on the principles of physical or biological sciences, engineering, or computer science.
  3. Elimination of Uncertainty: You must demonstrate that the activity seeks to eliminate uncertainty about the development or improvement of a product or process.
  4. Process of Experimentation: The activity must involve evaluating one or more alternatives to achieve a result. This can include modeling, simulation, systematic trial and error, or other methods.

Meeting these four criteria is essential for your expenses to qualify for the RD tax credit.

How is RD credit paid?

The RD tax credit directly reduces your tax liability on a dollar-for-dollar basis. If you owe $50,000 in taxes and qualify for a $20,000 RD tax credit, your tax liability would be reduced to $30,000. For startups with little to no income tax liability, the credit can be applied against payroll taxes, effectively putting money back into the business. Unused credits can be carried forward for up to 20 years, ensuring that even if you can’t use the credit this year, it won’t go to waste.

Understanding these frequently asked questions can demystify the RD tax credit process and highlight the potential savings for your business. Whether you’re innovating in technology, improving processes, or experimenting with new product developments, the RD tax credit offers a valuable opportunity to reduce tax liabilities and support your growth.
