R&D Tax Credits Engineers Can Rely On
Thoughtful R&D Credit Support for Engineering Firms and Their Tax Advisors
1. What is the R&D Tax Credit?
The federal Research & Development (R&D) Tax Credit is a general business tax credit available to companies that incur qualifying research expenses in the U.S. In addition to the federal credit, approximately 40 states offer their own R&D incentives.
The Credit is designed to encourage the development and improvement of products, processes, and technologies. For architecture firms, that work most often takes the form of design.
2. How Much Can Engineers Save with the R&D Tax Credit?
The R&D Tax Credit grows with you – the more you spend on research, the larger your Credit can become.
You can recoup up to 10 cents of every dollar spent on a qualified activity. This includes money spent on:
- Wages
- Payments to third-party contractors (including modeling-related fees)
- Supplies and materials
- Cloud hosting fees
If you spend $500,000 on qualified activities, you can claim a Credit of up to $50,000. Actual savings depend on the quality of documentation and methodology used to support the claim.
3. How Do Engineers Qualify for the R&D Tax Credit?
R&D Tax Credit eligibility is determined by activity. If a research activity passes all parts of the IRS’ Four-Part Test, it is eligible for the Credit.
The entire architectural design process can be considered a process of experimentation, and qualifying day-to-day activities include:
- Design and optimization of infrastructure, electrical, mechanical, and structural systems
- Material testing, modeling, and performance analysis
- Development of prototypes, blueprints, schematics, and first articles
- Evaluation of site constraints, loads, tolerances, and system interactions
4. What are the Benefits of the R&D Tax Credit for Engineers?
The R&D Tax Credit provides a dollar-for-dollar reduction in federal and state tax liability, directly improving cash flow. In many cases, architecture firms can recapture up to 10 cents for every qualifying dollar spent on design and development activities. The Credit can be captured retroactively for up to 3 previous tax years.
Many engineering firms are considered Qualified Small Businesses and may claim a modified version called the Payroll R&D Tax Credit, permitting them to offset payroll tax.
Could You Qualify?
Engineering firms across disciplines often qualify for the R&D Tax Credit if they:
- Create or improve custom designs, systems, or processes
- Perform CAD, BIM, RISA, or Revit modeling
- Solve technical problems and evaluate alternatives
If these activities are part of your normal operations, you may be eligible for the R&D Tax Credit.

The Capstan Way
R&D Tax Credits can be very powerful -- but they are also heavily scrutinized.
Many claims fail not because the research wasn’t legitimate, but because the Credit methodology or documentation couldn’t withstand review.
That’s where the right approach – and the right partner -- matters.
Not every activity qualifies, and not every dollar should be claimed. We tie qualified activities to qualified expenses, supporting results with detailed interviews, contemporaneous documentation, and technical analysis.
R&D Tax Credit FAQs: Engineering
Do engineering firms really qualify for the R&D Tax Credit?
Yes. Engineering firms frequently qualify when their work involves technical uncertainty and iterative problem-solving. Projects that require evaluating multiple design approaches, testing system performance, or resolving structural, mechanical, or electrical challenges likely meet the IRS definition of Qualified Research Activities.
Engineering firms can typically look back up to three open tax years to claim missed R&D credits.
What types of engineering work typically qualify for the R&D Tax Credit?
Qualifying activities often include system design and optimization, load and stress analysis, materials testing, modeling and simulation, prototype development, and performance testing. Work involving new applications, unique site conditions, or custom specifications is especially likely to qualify.
Does routine engineering or code compliance work qualify?
Routine work generally does not qualify on its own. However, when code or performance requirements introduce technical uncertainty that requires experimentation or evaluation of alternatives, related engineering activities may qualify.
Can unsuccessful designs or abandoned engineering approaches still count towards the R&D Tax Credit?
Yes. Engineering efforts that are revised, rejected, or never implemented may still qualify, provided the work involved technical uncertainty and a systematic process of evaluation and testing.
Can small or mid-sized engineering firms claim the R&D Credit?
Yes. The R&D Credit is not limited to large firms. Many small and mid-sized engineering firms qualify. The Credit can often be applied against income tax, and in some cases payroll tax, depending on circumstances.
Is claiming the R&D Credit risky for engineering firms?
Claiming the R&D Tax Credit is not inherently risky. Engineering firms with well-defined project narratives, thorough documentation, and IRS-aligned methodology are well positioned to defend their claims.
