The IRS spent over $10 million on blockchain analytics contracts between 2020 and 2024. Chainalysis, CipherTrace, and other firms provide tools that trace transactions across blockchains with forensic precision. If you think your crypto is private, you are operating on outdated assumptions.

Exchange Reporting

U.S. cryptocurrency exchanges are financial institutions under the Bank Secrecy Act. They file Currency Transaction Reports for transactions over $10,000. They issue 1099 forms reporting your gross proceeds. Starting in 2025, brokers must report cost basis and gain/loss information on Form 1099-DA. The IRS receives this data automatically — you do not need to be audited for them to know about your exchange activity.

John Doe Summonses

The IRS has served John Doe summonses on Coinbase, Kraken, Circle, and other platforms. These court-ordered demands compel exchanges to turn over records for all customers meeting certain criteria — not just specific individuals under investigation. The Coinbase summons alone covered over 14,000 accounts. Every customer whose records were produced is now in an IRS database.

Blockchain Analysis Tools

Chainalysis Reactor and similar tools map the flow of funds across public blockchains. They cluster addresses belonging to the same entity. They identify deposits into and withdrawals from known exchanges. They track through mixers, bridges, and cross-chain swaps with increasing accuracy. The IRS Criminal Investigation division uses these tools in every crypto case. On-chain privacy is not what most people believe it to be.

The AI Layer

The IRS is deploying machine learning models that identify patterns consistent with unreported crypto income. These systems cross-reference exchange data, blockchain analytics, and tax return information to flag discrepancies. The technology improves with every enforcement action because each case provides training data.

Compliance Is the Only Strategy

The enforcement infrastructure is built and operational. Attempting to hide crypto income is not a question of if you get caught but when. If you have prior-year exposure, correcting it voluntarily is the only strategy that consistently produces manageable outcomes. Attorney Darrin T. Mish has navigated these situations for three decades — the process is well-defined and the results are dramatically better than waiting.
