Emails can help support R&D tax credit documentation by showing the technical context and decision-making. This page explains how emails can support a credit claim. It is educational and is not individualized advice. For the general documentation concepts, see our page on R&D tax credit documentation.
How Emails Support the Uncertainty Element
Emails that discuss the technical question being addressed — what is uncertain about the capability, method, or design — can help support the elimination-of-uncertainty element. Emails written when the uncertainty existed tend to be more persuasive than summaries prepared later. For more, see our page on elimination of uncertainty.
How Emails Support the Alternatives Element
Emails that discuss alternative approaches — what alternatives are being considered, how they compare, and which should be tested — can help support the process-of-experimentation element. For more, see our page on process of experimentation.
How Emails Support the Decision-Making Element
Emails that document decisions — which alternative was selected, why, and what the results showed — can help demonstrate the evaluative process and how results informed decisions.
What Makes Emails Useful
Useful emails for R&D documentation tend to:
- discuss the technical question or uncertainty;
- discuss alternative approaches;
- discuss test results and what they mean;
- document decisions and the reasons for them;
- be contemporaneous — written when the work was occurring.
Hypothetical Example
Consider a manufacturer that has project emails discussing the technical uncertainty (whether a material can achieve the required strength), the alternatives being considered (three candidate materials), the test results, and the decision to select one material based on the results. These emails can help support the uncertainty, alternatives, and decision-making elements.
By contrast, emails that only discuss schedules or business matters, without technical content, are less useful.
These examples are illustrative only.
Key Takeaway
Emails can help support R&D tax credit documentation by showing the technical context, uncertainty, alternatives, and decision-making. Emails are most useful when they discuss technical questions and alternatives. Because documentation adequacy is fact-specific, professional review is appropriate.
