Seven Questions Engineering Firm Principals Ask About the R&D Tax Credit

TL;DR

• Client-facing design work can qualify for the R&D credit when it involves technical uncertainty and a process of evaluating alternatives, even though it never feels like "research."
• Client-funded projects are not automatically excluded. What matters is who bears the financial risk and who retains rights in the work, which comes down to contract terms.
• You do not have to guess whether it is worth pursuing. A no-cost initial assessment can size the opportunity before you commit to anything.

Engineering firms are one of the industries most likely to be doing qualifying work and least likely to be claiming the federal research credit under IRC Section 41. Part of the reason is vocabulary. Nothing about designing a foundation system or resolving a mechanical layout feels like "research and development," so principals assume the credit belongs to laboratories and software companies. When we talk with engineering firm owners and CFOs, the same questions come up again and again. Here are seven of them, with plain answers.

1. We do client projects, not research. Can design work really qualify?

Often, yes. The credit is not limited to white-coat research. Under Treasury Regulation 1.41-4, qualified research generally means work that is technological in nature, intended to develop a new or improved business component, undertaken to resolve technical uncertainty, and carried out through a process of experimentation. In an engineering firm, that can look like evaluating alternative structural systems for an unusual span, modeling and iterating a stormwater design for a constrained site, or working through competing HVAC configurations to hit a performance spec. Routine work has none of that. But when your team is testing alternatives because the answer was not knowable at the outset, the activity may qualify, depending on the specific facts and documentation.

2. Does the work have to succeed, or be new to our industry?

No on both counts. The regulation looks at whether the information you were seeking was uncertain to you at the start, not whether you were first in the field to solve it. Work that is new to your firm can qualify even if another firm somewhere has solved a similar problem. And failed approaches are often the clearest evidence that genuine experimentation occurred. A design direction you abandoned after analysis or testing may support a claim rather than weaken it.

3. Most of our work is client-funded. Doesn't that disqualify us?

This is the question engineering firms should take most seriously, and the answer is more favorable than many principals assume. The statute excludes "funded research," but funding is a contract-terms analysis, not a blanket rule. Broadly, research may still qualify where payment is contingent on the success of the work, meaning the firm bears financial risk, and where the firm retains substantial rights in the results, such as the ability to reuse methods and know-how on future projects. Fixed-fee arrangements where the firm eats rework often look different from fully reimbursed cost-plus work. Because this turns on the actual agreements, it deserves a careful read of your contracts rather than an assumption in either direction.

4. Whose time counts?

Potentially more people than you might expect. Qualifying wages can include employees directly performing the technical work, those directly supervising it, and those directly supporting it. In a typical firm that can reach beyond licensed engineers to designers, CAD and BIM staff working under an engineer's direction, and technical leads reviewing calculations. Certain supply costs and a portion of qualifying contract research expenses may also count. The credit is computed and claimed on IRS Form 6765, and the strength of the numbers depends on connecting each expense to the qualifying activity it supported.

5. Is claiming the credit going to invite an audit?

No claim can be made audit-proof, and you should be skeptical of anyone who promises otherwise. What a firm can control is defensibility. The IRS's own audit guidance for the research credit focuses heavily on substantiation: whether the taxpayer can tie claimed expenses to specific qualifying activities. A claim built on contemporaneous project records, reasonable qualification judgments, and clear documentation stands on very different footing from an aggressive estimate. That is the difference between maximizing a credit and inflating one.

6. We've been doing this kind of work for years. Can we go back?

Generally, yes, within limits. Businesses can often claim the credit for prior open tax years by filing amended returns, typically within the statute of limitations, which is generally three years from the date the original return was filed. Whether a lookback makes sense depends on the size of the potential credits, the state of your records for those years, and filing considerations your tax adviser can weigh in on.

7. What does it take to find out if this is worth pursuing?

Less than most principals expect. Strata provides an initial assessment at no cost, which sizes the potential credit before you commit to anything. A full study, when warranted, typically runs four to eight weeks depending on the engagement, and it is structured so that most of the work sits with our team rather than yours. We also work directly with your CPA, so the credit lands cleanly in your return rather than creating friction with the advisers you already trust.

The bottom line

If your firm regularly works through problems where the solution was not obvious at the start, the R&D credit is worth a real look. The questions above have general answers, but the ones that matter for your firm depend on your projects, your contracts, and your records. Reach out for a no-cost assessment and get a specific answer instead of a general one.
