HM Revenue and Trade (HMRC) has issued a warning to crypto investors: voluntarily recognizing debt on capital gains taxes or income tax on investments in digital assets will avoid penalties and claims from His Majesty’s Treasury.

The period for which UK crypto investors must calculate the amount of tax arrears is four calendar years from the date of filing the notice.

HMRC has advised taxpayers who have already provided tax information to the Treasury that they have 30 days from the date of disclosure to make all required payments. If the deadline is not met, the Treasury promises to take enforcement action and users may face fines.

Earlier, the United Kingdom Tax Office announced its intention to ease tax rules for participants in the digital asset industry, bringing their tax regime closer to the existing rules.
