HMRC has announced new rules aimed at pulling crypto firmly into the tax system.
From January 2026, anyone in the UK investing in crypto will be required to provide personal details including name, address, tax residency, and National Insurance number. Investing platforms and exchanges must report these details, along with a summary of transactions, or face penalties.
This is not a new tax. Capital Gains Tax has always applied to profits from selling or swapping crypto, and Income Tax can apply to earnings from activities such as staking, mining or lending. What is new is the level of scrutiny. Until now, crypto has existed in a grey area where enforcement was patchy and anonymity often shielded activity. That gap is closing.
The government expects the new framework to bring in up to £315 million by 2030. That’s being pitched as the equivalent of funding 10,000 newly-qualified nurses for a year, a framing designed to tie tax compliance to public services. Whether or not that holds sway with crypto traders is another question.
Brokers and exchanges will also be held accountable. Failing to report or providing incomplete data could result in fines of up to £300 per user. The rules form part of the OECD’s international reporting framework, meaning the UK isn’t acting alone. More jurisdictions are adopting similar measures, increasing the likelihood that crypto gains, however small, will be noticed.
For investors, this is a wake-up call. HMRC has already added crypto sections to Self Assessment forms, and is encouraging people to get their paperwork in order. The message is less about punishment and more about visibility, but fines are on the table for those who ignore the shift.
For years, crypto was sold as decentralised, anonymous and beyond the reach of traditional finance. Those days are fading fast. What comes next looks more like compliance than chaos.
