Got a letter from the IRS about your crypto? Here’s what IRS Letters 6173, 6174, and 6174-A mean in 2025 — and what to do next.
Since 2019, the IRS has sent out crypto “nudge” letters to US taxpayers. In 2025, these are still happening — and they’re more aggressive than ever. If you’ve received Letter 6173, 6174, or 6174-A, here’s what it means.
Letter 6173 – Action Required
This is the most serious. It demands a response and proof that you reported correctly. Ignoring it risks penalties.
Letter 6174 – Information Only
A “heads up” that the IRS knows you hold crypto. No reply required, but it’s a warning shot.
Letter 6174-A – High Suspicion
Similar to 6174 but worded more strongly. The IRS believes you underreported and may investigate.
What To Do
- Gather all your exchange & wallet records.
- Amend past returns if necessary.
- Get professional help if you’re unsure.
Conclusion
Don’t ignore IRS crypto letters. Acting fast can turn a potential audit into a smooth resolution.
