Q: What documents should we be retaining to claim the R&D Credit?

The MASSIE team answers:

No single document threshold governs an R&D tax credit claim. However, taxpayers must maintain reasonable records under Internal Revenue Code section 6001 and applicable case law. R&D documentation falls into two categories: records that support cost tracking, and records that substantiate qualifying research activities.

For cost tracking, the foundational documents include payroll reports, general ledgers, contractor invoices and contracts, and supply or job costing reports.

For the activities portion, taxpayers should retain two types of records: those that capture the technical uncertainty at issue, and those that document the experimentation undertaken to resolve it. Specifically, supporting records include technical recommendations and specifications, process flowcharts, design drawings, email correspondence, and testing procedures and reports.

Together, these records support a complete and defensible R&D credit claim. The right approach to retention depends on your business workflow. It also depends on the documentation your organization already produces. The strongest practice is contemporaneous collection as each project progresses. This ensures that key records don’t disappear once a project reaches completion. For organizations that can’t capture documents in real time, a semi-annual or annual collection tied to active R&D projects works well. In either case, the goal is the same: retain records that connect qualifying activity to specific costs before anyone asks for them.
