HMRC's Crypto Tax Crackdown: 81,000 Warning Letters Issued

HM Revenue & Customs (HMRC) is cracking down on UK cryptocurrency investors who may have underpaid tax. In the past year, the British tax authority sent 81,000 warning letters to crypto investors it suspects of underpaying taxes, a 25% increase from the previous year.

This number is expected to grow in the coming years as HMRC begins to receive automated information on UK residents' cryptocurrency transactions from exchanges operating across 52 jurisdictions. By 2028, an additional 15 countries will also provide similar data, giving tax investigators a clearer picture of investors' activities.

Neela Chauhan, partner at UHY Hacker Young, notes that many crypto traders assume HMRC has limited visibility over their activities. However, UK residents are subject to UK tax on worldwide income and gains, regardless of where transactions take place.

The complexity of cryptocurrency taxation is also a contributing factor. Investors may not realize that swapping one cryptocurrency for another can crystallize a taxable gain, or that income earned through lending digital assets creates tax liabilities.
