Before an R&D Review, Build This 6-Part Project Folder.

By US Biz Toolkit · October 8, 2026

Quick answer: A structured project folder makes a first conversation easier. It does not replace a professional eligibility review.

You do not need to begin with a glossy study. Begin with one project that your team can explain. The aim of this folder is to let a reviewer understand the story and locate the original evidence. It is a suggested organisation method, not a complete list of legal substantiation requirements.

1 and 2: The question and the people

Write a short description of what your team was trying to develop or improve. Explain what it did not know at the outset. Then list the people who can explain the work and their roles. Include the project owner and the accounting contact. Avoid assigning a tax conclusion in the folder title; call it a project review file.

3: The timeline

List major decisions, testing stages and revisions with dates. Link each entry to a source file where possible. If the timeline was prepared later from existing records, say so. A useful summary should help someone navigate evidence, not pretend to be a document written at the time of the work.

4: The underlying evidence

Keep technical notes, test outputs, drawings or design records in a consistent location. Preserve the originals and explain unfamiliar abbreviations. Ask the reviewer what else they need. Do not replace missing evidence with invented meeting notes. If access is restricted, agree on a secure sharing method before sending any proprietary files.

5: The cost map

Prepare a working index of the financial records associated with the project. Identify payroll periods, relevant purchases and outside agreements for discussion. Keep source amounts distinct from proposed allocations. Let the reviewer decide which expenses belong in the analysis and how they should be supported.

6: Questions and gaps

List uncertain dates, missing records, mixed activities and assumptions. In a hypothetical review, a team might know that it tested several alternatives but lack a clear link to particular time entries. Flagging that gap helps the reviewer focus the next request. Hiding it can create confusion later.

Agree on the handoff

Before sharing the folder, ask who will review it, whether the assessment has a fee and what output you will receive. Confirm how the final conclusions will reach your return preparer. Retain a copy of what you supplied and a list of later requests so the process stays organised.

Your next step

Download or adapt your own six-part folder structure. Read the documentation checklist and ask your reviewer which records are required for your circumstances.
