Can Engineering Firms Claim the R&D Credit on Client-Funded Projects?

TL;DR

• Client-funded engineering work is not automatically excluded from the federal R&D credit. The funded research rules turn on two contract questions: who bears the financial risk if the work fails, and who retains substantial rights in the results.
• Fixed-fee design contracts where the firm must deliver working results at its own risk can often support a claim; cost-plus or time-and-materials arrangements frequently cannot.
• A contract-by-contract review is the practical first step, and Strata offers a $0 initial assessment to do exactly that.

The question engineering firm owners ask us most

"Our clients pay for every project we do. Doesn't that mean the R&D credit is off the table for us?"

It is a fair question, and it is the single most common reason engineering firms never look at the federal research credit. The logic feels sound: if someone else funds the work, it must be their research, not yours. But the tax rules do not work on gut feel. They work on contract terms, and for many engineering firms, those terms tell a more favorable story than the owners expect.

What the federal R&D credit covers

The federal research credit under IRC Section 41 rewards companies for attempting to develop or improve products and processes through a process of experimentation. Treasury Regulation 1.41-4 (full text at eCFR) lays out the four-part test an activity generally must satisfy:

1. Technological in nature. The work relies on principles of engineering, physical science, biological science, or computer science. Structural, civil, mechanical, and electrical engineering work typically clears this bar comfortably.
2. Permitted purpose. The activity aims to create or improve a product or process in terms of function, performance, reliability, or quality.
3. Technical uncertainty. At the outset, the firm faces uncertainty about capability, method, or appropriate design.
4. Process of experimentation. The team evaluates alternatives through modeling, simulation, systematic trial and error, or other testing.

The IRS provides a general overview of the credit on its research credit page at IRS.gov.

The funded research rules, in plain English

Section 41(d)(4)(H) excludes research "funded" by another party. But funding, in this context, is a legal test, not a bookkeeping one. Under the regulations and the case law interpreting them, two questions generally matter:

Who bears the risk? If your firm is paid only when the work succeeds, or must correct failed designs at its own expense under a fixed-fee arrangement, you may bear the financial risk of the research even though a client is writing checks. If you are reimbursed for costs regardless of outcome, as in many cost-plus or time-and-materials contracts, the client likely bears the risk, and the work is more likely to be treated as funded.

Who keeps substantial rights? If your firm retains the right to use the know-how, calculations, design approaches, or methodologies it develops on future projects, that can support a claim of substantial rights, even when the client owns the final deliverable. If the contract assigns all rights in the work exclusively to the client, that weighs the other way.

Neither question can be answered from an income statement. They live in your master service agreements, purchase orders, and terms and conditions, which is why two firms with identical revenue can have very different credit positions.

What qualifying activity can look like at an engineering firm

Depending on the specific activities, documentation, and facts, qualifying work at engineering firms often includes:

• Developing novel structural solutions where standard details or published tables do not resolve the design problem, requiring iterative analysis or modeling
• Evaluating alternative foundation, framing, or materials approaches for unusual site conditions or performance requirements
• Designing and iterating on mechanical, electrical, or plumbing systems to meet aggressive energy, acoustic, or load targets
• Building or refining computational models, simulations, and internal design tools
• First-of-a-kind constructability work where the method of achieving the design intent is genuinely uncertain

Just as important is what typically does NOT qualify:

• Routine design work applying established standards and codes with no meaningful technical uncertainty
• Drafting, permitting, and construction administration
• Site surveys, inspections, and condition assessments performed to established procedures
• Aesthetic or purely stylistic design choices
• Work performed after technical uncertainty has been resolved, such as producing final construction documents from a settled design

An honest engagement separates the two. Claiming everything is how firms end up defending positions they should never have taken; claiming nothing is how they quietly subsidize their competitors.

What to do next

If you own or run finance for an engineering firm doing $3M to $15M in revenue, the practical path is a contract review paired with a project-level look at your technical work. Pull your three or four largest recent contracts and ask: were we paid to succeed, or paid to try? Did we keep any rights in what we learned? The answers usually point clearly in one direction.

Strata offers a $0 initial assessment that covers exactly this analysis, and most studies run four to eight weeks from kickoff, depending on records and responsiveness. If the contracts do not support a claim, you will know that too, which is worth something on its own. You can reach us here.

FAQ

Our contracts say the client owns all deliverables. Are we done before we start?
Not necessarily. Ownership of the deliverable and rights in the underlying research are separate questions. Firms may retain rights to reuse methods, calculations, and know-how even when the client owns the drawings. The contract language controls, so it is worth an actual read rather than an assumption.

We are an S corporation and the partners take most of the income. Does the credit still help?
Often, yes. For pass-through entities the credit generally flows to the owners' individual returns, subject to their own tax situations. A qualified advisor can model the impact before you commit to a study.

Can we look back at prior years?
Generally, open tax years, typically the last three, can be amended to claim credits for qualifying work performed in those years, depending on your filing history and circumstances.

Will claiming the credit trigger an audit?
No preparer can promise any particular IRS outcome, and you should be skeptical of anyone who does. What a firm can control is the quality of the claim: qualifying activities identified honestly, contracts analyzed properly, and documentation tied to the four-part test. That is the standard we build every study around.
