The Internal Revenue Service has intensified its outreach to cryptocurrency taxpayers, issuing an estimated 10,000 Letter 6174 notices each month. The letters, first introduced in 2019, inform recipients that the agency has information about one or more virtual‑currency accounts and urges a review of past tax filings. While the notices are framed as educational, industry observers say the volume signals a broader compliance push aimed at the rapidly growing crypto market.

Letter 6174 explained

Letter 6174 is classified by the IRS as a voluntary‑compliance notice. It states that the agency “has information that you have or had one or more accounts containing virtual currency” and that the taxpayer “may not know the requirements for reporting transactions involving virtual currency.” The notice does not cite specific discrepancies, nor does it require an immediate response. Instead, it advises recipients to consider filing amended returns or delinquent returns for any taxable year in which crypto activity may have been omitted.

Industry reaction

Clinton Donnelly, CEO of crypto‑tax firm Cryptotaxaudit, told Bitcoin.com News that the surge in letters is “alarming” and that dozens of his clients have reached out after receiving them. Donnelly noted that the letters were previously described as a “vague scare,” but the current cadence—roughly 10,000 per month—suggests a more systematic effort. He emphasized that a single letter does not imply wrongdoing and warned taxpayers against rushing to amend returns without understanding their position. On X, Ripple board member Joel Schwartz posted that he tossed his letter in the trash, calling it “basically just a reminder to follow the law.”

What taxpayers should do

Experts advise a measured approach. Review the notice carefully, confirm that all crypto transactions have been reported on the appropriate Schedule D or Form 8949, and consult a qualified tax professional before filing any amendments. The IRS states that Letter 6174‑A, a follow‑up notice, may be sent if the taxpayer fails to act, but neither letter requires an immediate reply. Taxpayers should retain documentation of their crypto holdings, transaction histories, and any prior filings to substantiate compliance if questioned later.

What to watch next

The next few months will reveal whether the IRS escalates the campaign into formal audits or maintains the current informational approach. Observers will monitor the frequency of Letter 6174‑A follow‑ups, any guidance updates from the Treasury Department, and potential legislative moves that could tighten crypto reporting requirements. Crypto‑focused tax service providers are also likely to see increased demand for compliance reviews, which could shape the market for specialized tax software and advisory services.
