Government funding doesn’t disqualify your research. But the wrong assumptions about it will.
Every year, aerospace, defense, and government contractors leave significant R&D tax credits unclaimed not because their research doesn’t qualify, but because they assume it doesn’t. The logic seems reasonable: the government paid for it, so the government gets the credit. Under IRC §41, that’s not how it works. And one landmark Federal Circuit decision makes that case better than anything else in the tax code.
Section 41 of the Internal Revenue Code allows companies to claim credit for qualified research expenses. There’s catch research that is “funded” by another party is excluded. And at first glance, a government contract looks like the textbook’s definition of funded research.
But Treasury Regulation §1.41-4 tells a more nuanced story. Research is only treated as funded if the taxpayer meets both of these conditions:
That second condition — retains no substantial rights — is where most contractors and many advisors stop reading. A company performing research under a fixed-price defense contract may retain more rights than it realizes. And those retained rights can be the difference between a disallowed claim and a six- or seven-figure credit.
In Lockheed Martin Corp. v. United States, the U.S. Court of Appeals for the Federal Circuit examined research performed by Martin Marietta (a Lockheed predecessor) under fixed-price defense contracts in the 1980s. The IRS denied the R&D credits. The Court of Federal Claims agreed. The Federal Circuit reversed at least in part.
The court’s reasoning was precise: the funded research analysis must focus on contract terms, not simply on who wrote the check.
Yes, the government received broad rights of licenses to patents, access to technical data, and recoupment provisions on certain commercial sales. But Lockheed retained the right to use the research in its own business without owing royalties to the government. That was enough.
Three principles emerged from the decision that continue to shape IRS examinations today:
This matters not just historically but in current practice. IRS examiners reviewing R&D credits for defense, engineering, and technology companies routinely scrutinize the funded research limitation. The Lockheed framework is the standard they apply.
The funded research rules create two distinct failure modes, and both show consistently in IRS examinations.
Companies performing work under government contracts often assume §41 simply doesn’t apply to them. They never conduct a contract-level analysis, never review their IP provisions, and never quantify what they might be entitled to claim. The credit goes unclaimed year after year.
A company assumes its research qualifies, includes costs in its return, and then faces an examination it isn’t prepared for. Without a documented review of contract terms and a clear record of which activities meet the qualified research definition, the credit becomes very difficult to defend.
Both mistakes are avoidable with the right methodology, and the Lockheed decision is essentially a roadmap for building it.
The Lockheed case also produced a cautionary ruling on refund claims that deserves far more attention than it typically gets. When Lockheed attempted to add additional research expenses after filing its original claim, the court rejected them under the “substantial variance” doctrine.
The rule is straightforward but unforgiving:
For companies with significant R&D credits at stake, the quality of your documentation at the time of filing is just as important as the technical merit of your research. A well-supported credit claimed correctly is far more defensible than a larger credit claimed carelessly.
The Lockheed decision established the legal framework. Applying it to a real company with dozens of contracts, thousands of line items, and years of project activity is an entirely different challenge. That’s where TaxDrone.AI and NTG (National Tax Group) work together to bridge the gap between legal principles and defensible execution.
TaxDrone.AI handles the documentation infrastructure:
NTG provides the strategic advisory layer:
Where TaxDrone.AI builds the record, NTG interprets it. Together, they address the two failure points that cost contractors the most: incomplete analysis of contract rights and insufficient documentation at the time of filing.
Most government contractors have already done the work. The research happened. The costs were incurred. The only question is whether the contract terms support a credit and whether the documentation is strong enough to defend it.
If your company performs research under government or customer contracts, reviewing the funded research rules under IRC §41 can significantly affect credit eligibility. Learn how our contract-level analysis approach works here.
