How Section 174 Is Revealing Hidden Data Problems Inside Large Tax Departments
By Scott Mueller, BBA, CPA, RTC Tax Manager, DST Advisory Group
For many large companies, handling Section 174 internally seems like the logical decision. The tax department already has access to the financial data, strong internal resources, and sophisticated systems. On the surface, it feels like something the organization should be able to manage on its own.
But over the past few years, we have seen a very different reality emerge. Let’s take a look inside Section 174 challenges.
At DST Advisory Group, we work with many Fortune 500 and Fortune 1000 companies on their Section 41 R&D tax credit studies. During those engagements, our team becomes deeply familiar with a company’s financial data, expense flows, project structures, and operational processes. We understand how engineering, finance, and tax information connects together because that is what defensible R&D tax work requires.
What has been interesting is what happens afterward.
Several large clients chose not to engage us for their Section 174 calculations because they planned to complete the work internally. That decision made sense to them at the time. After all, it was their data and their internal team.
Then the calls started coming in.
“Can you help us extract certain expenses?”
“Can you help us identify where this information sits?”
“Can you help us understand how these costs should be categorized?”
The data was always available to them. The challenge was not access. The challenge was interpretation.
Section 174 has exposed something many companies did not anticipate: having large amounts of financial data does not automatically mean you can apply tax rules to that data correctly and efficiently. The requirements are nuanced, the classifications are different, and the potential exposure areas are significant.
What starts as an internal efficiency initiative can quickly become a frustrating process involving rework, uncertainty, and pressure across departments. Tax teams often find themselves chasing engineering teams for information, reconciling inconsistent data sets, or second-guessing whether their methodology will stand up under scrutiny.
That is where specialized expertise makes the difference.
At DST, our technical team is made up of Tax Engineers, CPAs, and former IRS agents who understand both the technical and financial side of R&D tax incentives. That combination matters. It allows us to bridge the gap between raw data and defensible tax positions in a way many traditional providers cannot.
More importantly, it gives our clients confidence.
Confidence that the methodology aligns with the rules.
Confidence that the documentation supports the position.
Confidence that exposure areas are identified before they become problems.
In several cases, we assisted clients with their Section 174 work even when we were not formally engaged to do so. Not because they lacked capable internal teams, but because complex tax regulations require a level of specialization that goes beyond simply pulling numbers from a system.
The companies that navigate these rules most successfully are not necessarily the ones with the biggest internal departments. They are the ones willing to recognize where technical expertise can reduce risk, improve accuracy, and create long-term efficiency.
Section 174 is no longer just a compliance issue. It is a data interpretation challenge, an operational challenge, and ultimately, a strategic challenge.
