The Internal Revenue Service has issued a fresh warning after fraudsters began targeting cryptocurrency investors through counterfeit tax letters. The scam attempts to trick recipients into sharing sensitive information or transferring digital assets.
Unlike common phishing emails, this campaign relies on physical mail, making the documents appear more trustworthy. Consequently, officials urge taxpayers to verify every communication before responding. The agency also reminded crypto holders that legitimate tax notices never require payments through QR codes or unofficial online portals.
Fake Letters Create New Security Risks
Scammers reportedly instruct victims to register through a fraudulent digital asset compliance website. However, the IRS confirmed that no such portal exists. Additionally, criminals may encourage recipients to scan QR codes or answer calls requesting payments or personal information.
Therefore, taxpayers should ignore these requests and contact the IRS directly if they receive suspicious correspondence. Besides protecting private keys, investors should also review tax notices carefully before taking any action.
Crypto Crime Continues to Expand
The warning arrives as crypto-related crime continues to evolve. Moreover, security researchers recently reported more than $1 billion in losses from hacking incidents during the first half of 2026.
Criminals also increasingly rely on physical intimidation. Significantly, security firm CertiK recorded more than 50 wrench attacks during the same period, with Europe experiencing the highest number. Hence, investors now face growing threats from both sophisticated online fraud and real-world criminal tactics.
