On 3 September 2026, the IRS issued Notice 2026-XX, signaling a new phase of enforcement and compliance for the Section 41 research and development (R&D) tax credit. The notice outlines enhanced documentation requirements for taxpayers claiming the credit, including mandatory contemporaneous records that connect qualified research activities to business components, detailed time-tracking for employees engaged in qualified research, and substantiation of contract research expenses. The IRS also announced a targeted audit campaign focusing on industries with high credit claims relative to R&D spending, such as software development, pharmaceuticals, and manufacturing. The guidance reflects the agency’s increased focus on the “four-part test” (permitted purpose, technological in nature, elimination of uncertainty, process of experimentation) and the requirement that research be conducted within the United States.
Key Takeaways
- Contemporaneous Documentation Mandate: Taxpayers must now maintain project-level records created at or near the time the research is performed, including research plans, test results, design specifications, and meeting notes. Retrospective reconstructions using emails or oral testimony will no longer suffice for audit defense.
- Employee Time-Tracking Standards: The IRS expects precise allocation of employee hours between qualified and non-qualified activities. Companies should implement time-tracking systems that capture the nature of work performed, the business component involved, and the uncertainty addressed. Estimates or fixed percentages are discouraged.
- Contract Research and Supply Expenses: New rules require written agreements that explicitly identify the qualified research to be performed, the ownership of resulting intellectual property, and the right to use the research results. Payments for general engineering services or routine testing do not qualify. Taxpayers should review existing contracts and amend them to meet the new standards.
