What is IRS Letter 6174 or 6174-A?

IRS Letters 6174 and 6174-A are soft notices sent to taxpayers who may have failed to report cryptocurrency transactions. These letters are part of the IRS’s crypto compliance campaign and are informational, but they indicate the IRS has third-party data linking you to crypto activity. Letter 6174-A is slightly more urgent and implies closer scrutiny.
