When it comes to growing your business, every dollar matters. That’s where R&D Tax Credits come in. These incentives offer an excellent opportunity for companies to recover some of their research and development expenses.
In this guide, we’ll break down the R&D tax credit qualifications, explain how the R&D tax credit works, and show how your business — especially startups and growing companies — can claim and maximize these benefits with Haven.
Understanding R&D Tax Credits and Their Importance
R&D Tax Credits are a federal incentive designed to encourage businesses to innovate and invest in research and development activities. The payroll version of these credits specifically allows qualified small businesses to offset their employer-paid Medicare payroll tax liability. This program is critical for fostering economic growth and technological advancement by:
Promoting Innovation: Incentivizing investment in new product development and process improvements.
Recovering Expenses: Helping businesses, especially startups and early-stage companies, recoup a significant portion of their R&D costs.
Improving Cash Flow: Directly reducing payroll tax obligations, freeing up capital for reinvestment.
Supporting Growth: Providing a financial lifeline for companies not yet profitable, allowing them to reinvest in further innovation.
This robust program encourages businesses of all sizes and structures to invest in research and innovation, promoting economic growth and technological advancement across the board.
What are the qualifying activities for R&D tax credits?
At Haven, we specialize in identifying R&D tax credit-qualified activities that are often overlooked. These may include both technical and non-technical work.
If your company develops new products, improves existing ones, or enhances processes through technology or experimentation, you’re likely eligible. Common qualifying activities include:
Software development (internal or external)
Engineering design and analysis
Scientific experimentation and research
Prototyping and testing new concepts
Developing new manufacturing techniques
Improving product quality or performance
Implementing automation or efficiency solutions
The IRS Four-Part Test: A Simple Explanation
For any activity to qualify for R&D Tax Credits, it must satisfy the Internal Revenue Code Section 41 four-part test, as outlined by the IRS. This test ensures that the activities involve genuine innovation and technical challenge:
Permitted Purpose: The goal is to create or improve a product, process, or software.
Elimination of Uncertainty: There’s technical uncertainty around achieving the desired outcome.
Process of Experimentation: A systematic approach—testing, modeling, or trial and error—is used to resolve that uncertainty.
Technological in Nature: The work is based on scientific or engineering principles.
Example:
A startup developing an energy-efficient motor faces uncertainty about the best design to reach a new performance standard (Elimination of Uncertainty). Through simulations and prototypes (Process of Experimentation) grounded in mechanical engineering (Technological in Nature), the company’s project meets the R&D tax credit qualifications.
Eligibility Criteria and Business Types That Can Claim
R&D Tax Credit Eligibility: Which Businesses Can Qualify?
Your business may be eligible to apply the R&D tax credit against payroll taxes if:
You’ve had gross receipts for five years or fewer.
You have under $5 million in gross receipts this year.
You conduct activities that meet the IRS Four-Part Test.
Entity type rarely limits R&D tax credit eligibility. Most for-profit structures qualify, including S Corps, C Corps, LLCs, and partnerships. The only exception: non-profits, which have no tax liability to offset.
Eligibility Breakdown by Business Entity Type
Business Type | Eligibility for Payroll R&D Tax Credits | Special Conditions / Notes |
LLC, S Corp, C Corp | Eligible if meets gross receipt rules and R&D activity requirements. | Most common, can use against income tax or payroll tax (if qualified small business). |
Nonprofits (501c3s) | Not eligible. | Excluded from the R&D Tax Credit program. |
Early-stage Startups (Pre-revenue or \<5 years gross receipts) | Highly eligible with special consideration. | Specifically designed to use credits against payroll taxes. |
Small Businesses (Gross receipts \< $5M) | Highly eligible. | Can use credits against payroll taxes (and potentially income tax). |
Even pre-revenue startups can carry these credits forward as assets until they’re ready to offset payroll taxes — turning R&D work into long-term financial advantage.
How the R&D Tax Credit Works?
Businesses that innovate through product development or process improvement can generate substantial savings with Payroll R&D Tax Credits.
Key figures to know:
Up to $500,000 per year after the Inflation Reduction Act.
Approximately 10% credit on qualifying R&D expenses.
Five-year limit for payroll tax offsets (up to $2.5M total).
Unused credits can roll forward to future periods.
These limits show how R&D tax credit qualifications can lead to significant cash flow improvements and reinvestment opportunities.
