Top 10 Things Tax Teams Need to Know About R&D Tax Credits in 2025

The landscape for R&D tax credits is shifting. If your company relies on these incentives to fuel innovation, 2025 is bringing changes that demand attention. From new IRS scrutiny to documentation requirements that could make or break your claim, here’s what you need to know now—and what your finance team should be doing to stay ahead.

1. The IRS Is Treating All Taxpayers the Same—No More Exceptions

A few years ago, IRS audit campaigns targeted only select taxpayers. That’s no longer the case. Today, whether you’re a startup or a billion-dollar enterprise, expect the same level of scrutiny. The IRS isn’t showing deference based on company size, industry, or past compliance. Every claim is under the microscope.

Action Step: Ensure your R&D tax credit claims are bulletproof with clear documentation, data-backed calculations, and a well-structured business component strategy.

2. The New Form 6765 Is a Game Changer

The IRS is revamping Form 6765, adding new reporting requirements that demand more transparency. Key changes include:

• Detailed reporting on business components (you must now list the top 80% of Qualified Research Expenses across no more than 50 business components).
• More granular wage and supply cost breakdowns by business component.
• Mandatory identification of the specific scientific uncertainty your research is addressing.

Action Step: Don’t wait—adjust your internal R&D documentation process now. Start tracking and categorizing costs in a way that aligns with the new form.

3. 174 Capitalization Is Still in Limbo

Since 2022, companies have been required to amortize their R&D expenses over five years rather than deducting them immediately. The business community is still pushing for legislative relief, but for now, expect this requirement to remain in place—at least until Congress provides clarity.

Action Step: Work with your tax team to model out the financial impact of amortization and explore tax strategies that mitigate cash flow issues.

4. Refund Claims Are Under a Microscope

The IRS has made it clear: filing an R&D tax refund claim isn’t something to take lightly. If you submit a claim, expect a detailed review. The IRS has new “Classifiers” who evaluate whether claims meet specific documentation requirements before allowing them to move forward.

Action Step: Before filing, make sure you can provide:

• A complete breakdown of all business components.
• A clear explanation of what each research activity sought to discover.
• Detailed records of who performed the research and their role in the process.

5. IRS Audits Are Focusing on the “Process of Experimentation”

The IRS is tightening its interpretation of what qualifies as R&D. Companies must prove that at least 80% of their research efforts follow a structured process of experimentation—a requirement reinforced by recent court cases like Little Sandy Coal Co.

Action Step: Be prepared to demonstrate how your company followed the scientific method—hypothesis, testing, iteration—when developing new products or processes.

6. Software R&D Is Facing More Scrutiny Than Ever

Software-related R&D tax claims have long been a gray area. The IRS has struggled to define what qualifies, and the new Form 6765 adds more complexity. Companies must now classify software development activities into categories like Internal Use Software (IUS), Dual Function, or Non-IUS, each with different qualification criteria.

Action Step: If your company develops software, revisit your documentation process to ensure you’re categorizing expenses correctly under the new rules.

7. Business Component Strategy Is More Critical Than Ever

Companies can no longer rely on broad, vague categories when claiming R&D tax credits. The IRS expects a well-defined, defensible business component strategy that aligns with the new reporting requirements.

Action Step: Identify your company’s top 50 business components and ensure each one meets the IRS’s qualifications for R&D activities.

8. IRS Risk Assessments Have a New Gatekeeper: The Classifier

Before your claim even reaches an examiner, it goes through a “Classifier” who determines whether it’s worth reviewing. If the Classifier deems it weak, it may never make it past the initial screening.

Action Step: Strengthen your documentation and ensure every claim is audit-ready before submitting. Weak claims are more likely to get denied outright.

9. Pre-Filing Agreements Are Gaining Popularity

A little-known program called a Pre-Filing Agreement (PFA) allows companies to secure IRS approval on their R&D tax credit methodology before filing. While it requires an upfront investment, it provides certainty for up to five years.

Action Step: If your company claims large R&D tax credits annually, consider a PFA to minimize audit risk and ensure compliance.

10. The IRS Is Watching How You Document Your Claims

Interviews and internal notes aren’t enough anymore. The IRS wants to see real documentation—design iterations, test results, engineering notes, and other tangible evidence.

Action Step: Implement a documentation process that captures research activities in real-time rather than scrambling to reconstruct them later.

Don’t Get Caught Off Guard

2025 is shaping up to be a defining year for R&D tax credits. With increased IRS scrutiny, changing forms, and stricter compliance requirements, tax teams need to be proactive—not reactive.
