The IRS Criminal Investigation division employs over 2,000 special agents with the authority to carry firearms, execute search warrants, and make arrests. They have a dedicated cryptocurrency unit with blockchain forensics capability. Their conviction rate exceeds 90%. When a crypto tax problem becomes a criminal investigation, the stakes change completely.

What Triggers Criminal Investigation

The IRS refers cases for criminal investigation when they suspect willful conduct — intentional violation of a known legal duty. Red flags include: structuring transactions to avoid reporting thresholds, using mixers or privacy coins specifically to evade detection, filing returns that omit known exchange activity, maintaining offshore accounts without FBAR disclosure, and destroying records. The key word is willful — mistake and negligence are civil matters; intentional evasion is criminal.

The Crimes

Tax evasion under §7201 carries up to five years imprisonment and a $250,000 fine. Filing a false return under §7206 carries up to three years and $250,000. Willful failure to file under §7203 carries up to one year and $100,000. Conspiracy under §371 carries up to five years. These are federal felonies with real prison sentences — not theoretical penalties.

The Investigation Process

IRS CI investigations are conducted in secret. You may not know you are under investigation until agents arrive with a search warrant or a grand jury subpoena. The investigation can last months or years before charges are filed. During this time, everything you say to non-privileged parties — including your CPA — can be used against you.

Attorney-Client Privilege

This is where having an attorney matters most. Communications with your attorney are privileged and cannot be compelled. Communications with your CPA are generally not privileged and can be subpoenaed. If there is any risk of criminal exposure, retain an attorney before speaking to anyone else about your situation. Once you have spoken to a non-privileged party, those communications are discoverable.

Protection Through Compliance

The best protection against criminal prosecution is voluntary compliance. Coming forward before an investigation begins, filing corrected returns, and paying the tax demonstrates good faith that makes criminal prosecution unlikely. Attorney Darrin T.
