If your business develops new products, improves existing ones, creates software, or develops better ways to manufacture or deliver something, you may be eligible for the federal R&D tax credit.
You don't need a laboratory or a team of scientists to qualify. Businesses in industries ranging from manufacturing and software to agriculture and engineering may perform work that qualifies for the credit.
To qualify, an activity must meet the IRS requirements for qualified research, including all four parts of the R&D tax credit four-part test.
What Is the R&D Tax Credit Four-Part Test?
The four-part test is the framework the IRS uses to determine whether research activities are eligible for the federal R&D tax credit under Internal Revenue Code Section 41.
The test consists of four requirements:
- Permitted Purpose: The research must relate to creating or improving a business component, such as a product, process, software, technique, or formula.
- Technological in Nature: The research must rely on principles of the physical or biological sciences, engineering, or computer science.
- Elimination of Technical Uncertainty: The company must face uncertainty about the capability, method, or appropriate design of the business component.
- Process of Experimentation: The company must evaluate alternatives through a systematic process of testing, analysis, and refinement.
All four requirements must be met for an activity to qualify for the federal R&D tax credit.
1. Permitted Purpose
Qualified research must be undertaken to create a new or improved business component. Improvements may relate to the component's functionality, performance, reliability, or quality.
A business component can include a product, process, software, technique, formula, or invention that the company develops for sale, lease, license, or use in its business.
For example, a manufacturer developing a more durable component may test different materials and designs to determine which combination achieves the required performance. A software company may qualify while developing new functionality that requires solving technical problems.
2. Technological in Nature
Qualified research must rely on principles of the physical or biological sciences, engineering, or computer science.
An engineering team might apply physics and engineering principles to develop a new component. A manufacturer may use engineering principles to test different production methods. A software company may rely on computer science to develop and test new functionality.
The industry itself doesn't determine eligibility. What matters is whether the work relies on an appropriate field of science or engineering.
3. Elimination of Technical Uncertainty
Qualified research must involve technical uncertainty at the beginning of the development process. The company may be uncertain about the capability, method, or design needed to achieve the desired result.
For example, suppose a manufacturer wants to develop a component that can withstand higher temperatures but doesn't know which material or design will work. That uncertainty about how to achieve the desired performance may qualify if the company conducts research to resolve it.
The fact that a project ultimately succeeds doesn't eliminate the uncertainty that existed during development. The question is whether the company faced genuine technical uncertainty and conducted research to resolve it.
4. Process of Experimentation
The company must also use a process of experimentation to evaluate alternatives and resolve technical uncertainty.
Experimentation doesn't necessarily mean formal laboratory testing. Depending on the project, it can include:
- Developing and testing prototypes
- Evaluating different designs
- Testing alternative materials
- Running simulations or models
- Testing different software approaches
- Analyzing test results and refining a design
The process should involve testing different approaches, analyzing the results, and using what the company learns to guide further development.
For example, an engineering team might compare several designs against the project's performance requirements. A software team might test different technical approaches to determine which one provides the required performance.
The goal is to use testing and analysis to find a solution to a technical problem.
Does an Activity Have to Pass All Four Parts?
Yes. All four requirements must be met for an activity to qualify for the federal R&D tax credit.
A project can have a legitimate business purpose and involve technical work without meeting the test. If the company wasn't facing technical uncertainty or didn't use a process of experimentation to resolve it, the activity may not qualify.
Simply calling something "R&D" isn't enough. Eligibility depends on what the company actually did during the development process.
Examples of Activities That May Qualify
The four-part test can apply to a wide range of technical activities. Examples include:
|
Activity |
Example of qualifying work |
|
Developing new software |
Testing different technical approaches to achieve a desired functionality or performance. |
|
Improving a manufacturing process |
Testing different production methods to improve efficiency, quality, or performance. |
|
Developing a new product or component |
Testing different designs or materials to meet specific technical requirements. |
These examples aren't automatically eligible for the credit. The specific work performed must be evaluated against all four parts of the test.
How Acena Can Help
Passing the four-part test is only one part of claiming the R&D tax credit. Businesses also need to identify qualified research expenses, establish which costs are eligible, and maintain documentation to support the claim.
Acena Consulting works with businesses to identify potentially qualifying activities and evaluate the technical work behind them. Our team of tax professionals and engineers can help connect those activities with the documentation needed to support a credit claim.
If you're unsure whether your company's activities qualify, schedule a consultation with Acena Consulting to discuss your situation.
