The U.S. Internal Revenue Service has issued an urgent warning to cryptocurrency investors about a new scam that uses physical mail to steal funds and personal information. Fraudsters are sending counterfeit tax letters that instruct recipients to register on a fake “Digital Asset Compliance Portal,” a platform the IRS confirms does not exist. The letters are designed to create a sense of urgency by exploiting the increasing familiarity with tax obligations for digital assets.
The scam marks an evolution in crypto fraud tactics. Unlike typical phishing emails, these physical documents appear more credible and may include QR codes or phone numbers prompting victims to share sensitive data or transfer cryptocurrencies. The IRS emphasized that legitimate tax notices never demand payments through QR codes or unofficial websites. Officials urge anyone who receives such mail to ignore it and verify any communication directly through official IRS channels.
This alert comes amid a broader surge in crypto-related crimes. Reports indicate that total losses from hacks and scams surpassed $1 billion in the first half of 2026 alone. The physical mail approach adds a new layer of risk by exploiting trust in traditional correspondence. Investors are advised to maximize wallet security, avoid sharing private keys or credentials, and treat all unsolicited tax-related letters as suspicious.
