The United Kingdom has confirmed that new reporting rules for cryptocurrency platforms will come into force as part of the national budget plan for 2025. These requirements mark a major effort to ensure that cryptocurrency investors accurately disclose their profits to the UK tax authorities.
Starting January 1, 2026, cryptocurrency trading platforms operating in the country will be required to collect detailed information from customers about their cryptocurrency transactions, including tax reference numbers, and submit the data to HM Revenue & Customs (HMRC) the following year.
The initiative is part of the Cryptoasset Reporting Framework (CAFR), a global cooperative effort designed to increase tax transparency within the digital asset industry.
Penalties for non-compliance
Investors who refuse to provide the required information can face fines of up to £300. Trading platforms that fail to report customer details can also be fined £300 per unreported user, which could result in significant financial penalties.
HMRC will check the new reporting data against submitted tax returns and identify individuals who have not properly declared cryptocurrency-related earnings. The UK Government estimates that stronger enforcement measures could generate more than £315 million in additional tax revenue by April 2030, enough to support significant public spending, including on healthcare staff.
HMRC officials emphasize that this is not a new tax, but a stricter application of existing capital gains rules. Investors are urged to make sure they understand what information they need to provide to crypto platforms.
Future challenges for crypto platforms
Tax specialists warn that collecting and verifying detailed personal data can be difficult for trading platforms, especially given the privacy-conscious nature of many cryptocurrency users.
Exchanges will need updated systems to store, validate and report accurate customer records. Any failures, including late submissions, missing information or poor due diligence procedures, could lead to harsh penalties from HMRC.
These operational changes are expected to be costly, and experts predict that crypto companies could eventually pass on compliance expenses to merchants through higher fees.
There is also the potential for users to look for ways to circumvent regulated platforms, a pattern seen in other financial sectors when strict reporting rules were introduced.
DeFi taxes still under review
While confirming progress on CAFR, the government also released an update on how loans and staking on decentralized finance (DeFi) could be taxed in the future.
The initial guidance suggests that HMRC could support a “no gain no loss” approach, meaning that taxable events would only occur once assets are converted or withdrawn, rather than during ongoing lending or liquidity pool activity.
However, no final decision has been made and the government plans to continue consulting industry stakeholders before setting a timeline for policy implementation.
