If the IRS opens an examination of a year with significant crypto activity, they will request transaction records, wallet addresses, exchange account statements, methodology documentation, and evidence that your accounting was internally consistent. Most taxpayers don’t have this organized. This post provides the exact checklist Chainblock Financial uses to build an audit-ready file before any notice arrives: what to preserve, how to format it, how long to keep it.

1. What the IRS actually requests in a crypto examination: the standard IDR
If the IRS opens an examination of a year with significant crypto activity, they will request transaction records, wallet addresses, exchange account statements, methodology documentation, and evidence that your accounting was internally consistent. Most taxpayers don’t have this organized. This post provides the exact checklist Chainblock Financial uses to build an audit-ready file before any notice arrives: what to preserve, how to format it, how long to keep it.
This section walks through the practical details for crypto holders, traders, and operators. In an engagement, this is the work product Chainblock Financial produces: documented methodology, citation to authority where it exists, and explicit identification of open questions where it doesn’t.
Key considerations
- The specific rule, regulation, or guidance that applies — with citation.
- Where the guidance is silent and a defensible position has to be taken.
- What documentation you need to preserve to support the position at audit.
- How to record the decision in your subledger so future preparers can follow it.
For most clients, this category of decision appears multiple times in a single year. Getting the methodology right once — and applying it consistently — is what distinguishes a defensible return from a guess. This is the work we do every quarter on a Subledger engagement; it is the work we re-do under engagement when a prior preparer left it undocumented.

This is the work we do.
Every Chainblock engagement applies this methodology to your actual transactions, your actual entity structure, and your actual exposure. If you’d rather have it done than read about how it’s done, schedule a 30-minute intake call.
