Here's the answer most agency owners never get. If your agency does client work, the R&D tax credit probably isn't yours, and the reason has nothing to do with how well you documented it. Four exclusions written into the law land directly on how agencies operate, and no amount of paperwork moves them.
There is a real version of this credit for agencies. It applies to proprietary technology you funded yourself, at your own risk, and own. That's a narrow door, but it's a genuine one, and some owners have walked past it for years. We recently had a client receive a real credit of more than $125,000 for a single year.
I've been a CPA for more than 23 years, and my firm works with more than 70 marketing and advertising agency owners every month. I'm writing this because the calls have gotten aggressive, and because I don't get paid a percentage of your credit. That's the whole reason I can tell you no.
One scope note before we start: this is the United States federal credit under IRC Section 41. The UK, Australian, and Canadian programs are different regimes, and none of this applies to them.
Because the credit is generous and an industry grew up around finding it.
Many of those firms work on contingency, taking a percentage of whatever credit they identify. I'm not going to tell you every one of them is acting badly. Plenty do careful work.
But you should see the incentive clearly. The person paid a percentage of your credit is structurally the wrong person to ask whether you qualify for it. And when the IRS disallows a claim, the vendor isn't the one who signed the return. You are.
The credit's definition of qualified research is narrower than the marketing suggests, and the Instructions for Form 6765 list the exclusions plainly. Four of them are fatal for typical agency engagements.
1. Research funded by another person. If someone else pays for the work and bears the financial risk, it isn't your research. Your client engaged you, your client paid you, and if the project underdelivered you still invoiced. That's funded research, and it's out.
2. Research adapting an existing product or process to a particular customer's need. That's the statutory language, close to verbatim. Now describe a normal agency project: you take an approach you know works and you fit it to this client's market, budget, and goals. That's adaptation to a particular customer's need, and it's out.
3. Surveys and studies. Excluded by name. Market research, audience segmentation work, brand studies, competitive analysis.
4. Research in the social sciences, arts, or humanities. Excluded. Creative development, copywriting, design, messaging strategy, content. The work your agency is actually known for.
Read those four together and you've described the majority of what an agency sells. That's why this is a structural problem rather than a recordkeeping problem, and it's why a better study can't fix it. A study documents activity. It can't change the category the activity falls into.
The credit is looking for something specific: technical work you funded, whose outcome was genuinely uncertain, on something you own.
For an agency, that usually means proprietary technology rather than client deliverables:
The test to run in your head is three questions. Did you pay for it? Was the outcome uncertain when you started? Do you own the result? Three yeses and you're worth a conversation. A single no and you're probably outside.
One more hurdle if the software is only for internal use. Internal-use software has to clear what's called the high threshold of innovation: it must be genuinely innovative, involve significant economic risk, and not be something you could have bought commercially without substantial modification. That's a real test with real teeth, not a formality, and it's where a lot of "we built our own dashboard" claims fall apart.
Vendors blur these constantly. Keep them separate, because one of them involves a deadline that has already passed.
The deduction is Section 174. For several years, businesses had to capitalize research costs and amortize them rather than deducting them currently, which hurt cash flow for anyone doing development work. New Section 174A reversed that going forward: domestic research expenditures are currently deductible again for tax years beginning after 2024.
There was also a transition provision letting certain smaller businesses go back and recover unamortized amounts from tax years beginning after 2021 and before 2025. That election's deadline was July 6, 2026. It has passed. The procedures live in Rev. Proc. 2025-28. If a vendor is currently pitching you that catch-up election, they're selling a door that closed roughly a month ago, and that tells you something about how current their information is.
The credit is Section 41. Separate provision, still fully available, and still claimable on amended returns for open tax years. When people say "R&D tax credit," this is what they mean.
You can qualify for the deduction and not the credit. Many agencies with any development spend are in exactly that position.
You'll hear about this one, and for almost every established agency it's a dead end. I'm including it so you can rule it out quickly rather than get excited and then disappointed.
A qualified small business can elect to apply up to $500,000 of the credit against the employer portion of Social Security tax rather than income tax, which matters if you're not yet profitable. But the eligibility test has two parts, and the second one disqualifies nearly everybody reading this: you need gross receipts under $5 million for the year, and no gross receipts at all for any tax year before the five-tax-year period ending with the current year.
That second condition makes this a genuine startup provision. If your agency has been billing for more than five years, you're out, regardless of your size. There's also a five-year lifetime cap on making the election.
One compliance change worth knowing, because it affects how much work a claim takes.
Form 6765 has a Section G requiring the credit to be broken out by business component, reporting at least 80% of total qualified research expenses and no more than 50 components. It was optional for tax years before 2026. It's required for tax years beginning after 2025.
Most agencies fall inside the exemption, so don't panic: you're excused if you're a qualified small business electing the payroll tax credit, or if your qualified research expenses are $1.5 million or less and your average gross receipts are $50 million or less, on an original return.
The direction of travel is still worth reading. The IRS is asking claimants to show the work at the project level. Claims built on a spreadsheet of payroll allocations and a narrative are getting harder to defend, which is exactly the kind of claim a volume vendor produces.
One more preparer-level item, mentioned so you recognize it on your return: the Section 280C reduced credit election takes the credit at 15.8% instead of 20% but avoids reducing your deduction. It has to be made on an original, timely filed return, it can't be made or changed on an amended return, and it's irrevocable for that year. That's a decision to make deliberately with your CPA rather than discover afterward.
Agencies that do client services and nothing else. If everything you produce is paid for by a client and shaped to that client's needs, this credit isn't where your money is. That's not a failure and it's not a reason to stretch. Your real opportunities are in entity structure, retirement plan design, reimbursement policy, and owner compensation, and every one of them is more reliable than a contested credit.
Anyone whose vendor says their creative team's time qualifies. Creative work sits inside the arts and humanities exclusion. Get a second opinion before you file.
Anyone hoping to claim the expired 174 catch-up election. That window closed July 6, 2026.
Agencies looking for a cash-flow fix right now. Even a legitimate credit takes documentation, a return, and time. It isn't a liquidity tool.
Run the three questions on any project you think might qualify: did you pay for it, was the outcome uncertain, and do you own it. Write down the honest answers.
If you get three yeses on something real, it's worth a proper look, and a proper look means a technical analysis tied to specific projects rather than a percentage-of-payroll estimate.
If you don't, decline the study and put the energy somewhere with a better return. Filing a return isn't a tax strategy, and neither is chasing a credit that the statute already excluded.
Book a Free Tax Analysis and we'll tell you which side of that line you're on. Sometimes the most valuable thing we do is talk somebody out of a claim they'd have lost.
Let's talk.
Usually not for client work. Four Section 41 exclusions apply directly: research funded by another person, research adapting an existing product or process to a particular customer's need, surveys and studies, and research in the social sciences, arts, or humanities. Client projects are typically funded by the client, adapted to that client, and substantially creative, which puts them outside the credit. An agency can qualify for proprietary technology it funded at its own risk and owns.
No. Research in the social sciences, arts, or humanities is specifically excluded from qualified research under Section 41. Copywriting, design, messaging strategy, and creative development don't qualify regardless of how innovative or technically demanding the work was. If a vendor tells you your creative team's hours qualify, get a second opinion before filing.
Section 174 (now Section 174A) governs the deduction for research expenditures, and domestic research is currently deductible again for tax years beginning after 2024. Section 41 is the tax credit, a separate and narrower provision with its own four-part test and exclusions. You can qualify for the deduction without qualifying for the credit, which is the position most agencies with development spending are in.
Yes. The election allowing certain small businesses to recover unamortized research amounts from tax years beginning after 2021 and before 2025 had a deadline of July 6, 2026, and that date has passed. The procedures are in Rev. Proc. 2025-28. If someone is still offering to make this election for you, treat that as a signal about the quality of their information.
Almost certainly not, if you've been in business more than five years. The election requires gross receipts under $5 million for the tax year and no gross receipts for any tax year before the five-tax-year period ending with the current year. That second test makes it a startup provision. The maximum is $500,000 per year against the employer portion of Social Security tax, with a five-year lifetime limit on electing.
Be careful. The model pays a percentage of the credit identified, which rewards finding credits rather than screening them out. Some firms do rigorous work, but you're the one who signs the return and carries the exposure if the claim is disallowed. At minimum, have someone with no financial stake in the answer review the qualification analysis before you file.
