Will a Credit Study Eat Your Billable Hours? What Engineering Firms Can Expect
Engineering firms run on utilization, so the first question about an R&D credit study is usually about time, not eligibility. This post explains, at a high level, what a study asks of your people and what lands on your desk at the end.

TL;DR
- Engineering firms often hesitate on the R&D credit because of utilization, not eligibility. A study that pulls principals and project engineers off billable work can feel like a cost before it feels like a benefit.
- A guided study is designed so that most of the work sits with the provider, and the time asked of your people is modest. Typical turnaround is four to eight weeks, depending on the specific activities, documentation, and facts.
- Your existing timesheets and project files do much of the heavy lifting. You end up with a documentation package built to support the claim, which you hand to your CPA.
The objection is usually about time
When we talk with engineering firm owners, the first question is rarely “do we qualify?” It is “how many hours will this take from my people?”
That is a fair question. Your revenue is tied to utilization, and every hour a project engineer spends on something non-billable shows up in the month’s numbers. A principal who is also your best technical reviewer is exactly the person you least want in a long series of meetings. If the credit study looks like a second job, it is easy to put it off another year.
The good news is that this concern is about the design of the engagement, and it is one a well-run process is built to address.
First, a quick grounding on what the credit is
The federal research credit under IRC Section 41 generally rewards businesses that spend on qualified research, including wages for employees who perform, directly supervise, or directly support that work. Under Treasury Regulation 1.41-4, the activity generally has to be aimed at eliminating technical uncertainty through a process of experimentation, and it does not have to succeed to count. For an engineering firm, that can include design work where the method or capability was genuinely uncertain at the outset, depending on the specific activities, documentation, and facts.
That is all the eligibility we need for this post. The question here is what the work looks like from your side of the desk.
What a study asks of you
At a general level, a study asks three things of an engineering firm.
Background on how your work runs. Your provider needs to understand your firm: the kinds of projects you take on, how you are paid, and how your people record their time. Much of this already exists in your accounting and project systems, so the ask is generally to share what you have rather than to create something new.
A small amount of input from a few people. Someone has to tell the story of the technical work, and that has to come from the people who did it. A study generally asks for focused input from the engineers and principals closest to the work, not from the whole firm for weeks at a time. The aim is to keep each person’s commitment short and to schedule it around your project deadlines.
A decision-maker who can say yes to the findings. Someone with authority, usually an owner or CFO, reviews the results and confirms they reflect how the firm actually operates.
We are deliberately not laying out the mechanics of our process here, and the specifics are tailored to each firm. What matters for your planning is the shape: a small, bounded ask on your side, with most of the work sitting with the provider.
What your existing records already do for you
Engineering firms are often better positioned than they realize. If you track time by project, you already hold much of what links wages to specific work. If you keep design reviews, calculation packages, revision histories, and RFI logs, you already hold much of the evidence of how technical problems were worked through. A study mostly organizes and interprets what exists. It rarely asks you to start a new tracking regime, although many firms find that a few small habits make future years easier.
What the first look costs you
A $0 initial assessment is a reasonable way to test the water. It is designed to give you a read on whether a credit looks likely to be meaningful for your firm before you commit to anything. A 15-minute conversation is typically enough to size it up at a high level.
What lands on your desk at the end
When the work is complete, you receive a documentation package built to support the claim. You pass it to your CPA, who files it with your return. Strata does not file your return and does not speak with the IRS on your behalf, so your existing tax relationship stays as it is. Individual results vary, and timing depends on how quickly your records and input come together.
How to decide when to start
Many firms assume there is a right season for this and wait for a slow stretch that never comes. Because the ask on your side is modest, there is usually no need to wait for a lull. A better trigger is a simple one: pick a time when the person who knows your project history best can spare a few short windows, and when your CPA will have the package in time for the filing you have in mind.
If you are weighing it
If you run an engineering firm in the multi-million range and you have been putting this off because of what it might do to utilization, a short conversation can help you see the real size of the ask before you decide. Book your 15-minute review at stratataxgroup.com/contact.
