UK Tightens Crypto Tax Compliance With Voluntary Disclosures
The UK tax authority has recovered more than £8.3 million from cryptocurrency investors through voluntary tax settlements, highlighting a broader push to improve compliance as HM Revenue & Customs (HMRC) prepares for expanded data-sharing powers and stricter reporting requirements.
Summary:
- More than 500 UK crypto investors voluntarily settled unpaid tax liabilities through HMRC’s disclosure facility.
- The tax authority is expanding compliance efforts as international crypto reporting rules take effect.
- The Treasury expects crypto taxation to generate £315 million in revenue by the end of the decade.
According to information from Financial Times, 502 crypto investors settled outstanding tax liabilities through HMRC’s Cryptoasset Disclosure Facility, which allows taxpayers to report unpaid crypto taxes before becoming the subject of a formal investigation.
The settlements generated approximately £3.5 million during the 2024/25 tax year from 280 individuals, followed by another £4.8 million from 222 investors in 2025/26.
The disclosure facility, introduced in late 2023, is intended to encourage taxpayers to correct previous reporting errors voluntarily, typically resulting in lower penalties than cases resolved through formal enforcement proceedings.
Tax advisers say the figures likely represent only a small portion of investors with undeclared crypto gains, as many remain unaware that selling digital assets, exchanging one cryptocurrency for another and certain NFT transactions may all trigger capital gains tax obligations.
HMRC Expands Crypto Compliance Efforts
Alongside voluntary disclosures, HMRC has significantly increased its compliance activity.
The tax authority issued nearly 65,000 “nudge letters” during the 2024/25 tax year, representing a roughly 680% increase from previous levels. The letters encourage taxpayers to review their crypto transactions and correct any reporting errors before further action is taken.
HMRC has also widened its scrutiny beyond income and capital gains, examining digital assets disclosed through inheritance tax filings where appropriate.
The increased enforcement reflects the UK’s broader effort to narrow tax gaps as cryptocurrency ownership continues to expand.
International Reporting Rules Strengthen Oversight
HMRC’s compliance capabilities are expected to grow further following the implementation of the Crypto-Asset Reporting Framework (CARF).
Since Jan. 1, 2026, UK-based cryptoasset service providers have been required to collect customer identification, tax residency and transaction information for reporting purposes. The framework enables participating jurisdictions to automatically exchange that data, making it more difficult for taxpayers to conceal crypto assets held through overseas platforms.

The tax authority has also integrated dedicated cryptocurrency reporting into the UK’s Self Assessment system, allowing declared gains to be cross-checked against information received from exchanges and other reporting entities.
Treasury Eyes £315 Million by 2030
The UK government expects stronger reporting requirements and expanded enforcement to increase tax receipts from digital assets over the coming years.
The Treasury has projected that crypto taxation could generate £315 million in revenue by 2030, based on an estimated 7 million cryptocurrency holders across the UK.
Combination of voluntary disclosure programs, automated international reporting and increased compliance activity signals a shift toward more systematic oversight of cryptocurrency taxation, reducing the scope for undeclared gains while encouraging investors to regularize past filings before enforcement intensifies.
