The federal ruling in Little Sandy Coal Company v. Commissioner is now one of the clearest indicators of how the IRS evaluates R&D tax credit claims. The case denied more than $3.26 million in credits for a shipbuilder that designed and built two highly customized vessels. Even though the work involved significant technical challenges, none of the claimed credit survived review.
This decision highlights a shift that affects every company claiming R&D credits today. Innovation alone is no longer enough. The IRS expects documentation that clearly shows what work qualified, how it was carried out, and how each cost supports the claim.
For businesses developing new products, improving processes, or testing new concepts, this case serves as a roadmap for the level of clarity required. National Tax Group and TaxDrone.AI help organizations meet that standard by combining R&D tax expertise with structured, real-time documentation tools.
The court did not question whether the shipbuilder worked on difficult engineering problems. The vessels were custom-built, and the work involved real design challenges. The issue was not the activity itself, but the lack of documentation showing how that activity aligned with the IRS definition of qualified research.
Several factors led to the complete denial of the credit.
The IRS evaluates R&D work by business component. In this case, the company combined activities and wages for two separate vessels without distinguishing which work belonged to which project. Without this clarity, the court had no basis to evaluate experimentation for each vessel.
Employee time was assigned using broad percentage estimates. The court rejected these as unsupported. Under IRS regulations, records must be detailed and usable, not reconstructed or approximated after the fact.
Tasks such as drafting, purchasing, management, and quality checks were included as research activities. However, the court found no evidence of hypotheses, alternatives, or testing that would qualify these tasks as experimentation.
To qualify for the R&D credit, companies must demonstrate that they faced technical uncertainty and evaluated different approaches to resolve it. In this case, the documentation did not show what decisions were being tested or how the team assessed alternative designs.
The IRS requires that substantially all of the research activities involve a process of experimentation. The judges stated they could not compute the test at all because the record lacked a usable breakdown of activities and wages. Without this calculation, the credit could not stand.
The court summarized the source of the problem in one line: “We walk by sight, not by faith.”
In other words, the IRS cannot rely on assumptions. It must see the evidence.
The Little Sandy Coal decision reflects a broader trend. The IRS is requesting clearer, more structured documentation than ever before. Companies cannot assume that general descriptions of engineering or development work will be enough.
To support an R&D credit, businesses need documentation that shows:
Companies that rely on year-end interviews, spreadsheets, or reconstructed timelines often struggle to meet this standard. Details are forgotten, work becomes difficult to separate, and the story loses clarity.
This is exactly where National Tax Group and TaxDrone.AI can help.
The issues exposed in the Little Sandy Coal decision are not unusual. Many companies run into similar challenges because innovation happens daily, but documentation often happens later.
National Tax Group and TaxDrone.AI work together to close this gap.
NTG helps companies identify qualifying projects, separate routine tasks from experimentation, and document work in a way that aligns with IRS requirements. This structure ensures that routine tasks are separated from experimentation and that each part of the claim reflects current requirements.
TaxDrone.AI complements NTG’s expertise by creating records as work happens. The platform provides:
Together, NTG and TaxDrone.AI give companies the visibility the court said was missing in the Little Sandy Coal case.
The Little Sandy Coal decision illustrates the evolving reality of R&D credit compliance. Credits are no longer secured by the complexity of the work alone. They are secured by documentation that clearly shows how experimentation occurred and how each cost supports that work.
Companies that build structured, real-time documentation into their process will be far better positioned under today’s IRS standards. With National Tax Group and TaxDrone.AI, that level of clarity becomes achievable, consistent, and built into daily operations. Book a Demo.
