If you hold, trade or earn cryptocurrency, an important change has already taken effect. Since the start of this year, HMRC now receives far more information about crypto activity than ever before and that has real implications for contractors.
These changes are not about banning crypto or discouraging investment. Instead, they bring digital assets firmly into the mainstream tax system.
Cryptocurrency exchanges and wallet providers are now required to automatically report user information and transaction data to HMRC.
This means HMRC no longer needs to rely solely on what individuals choose to disclose. Instead, it can cross-check tax returns against data provided directly by crypto platforms.
In simple terms, crypto is now treated much more like shares, property or other financial assets when it comes to tax visibility.
The reporting rules apply to crypto-asset service providers that deal with UK residents. This includes platforms based in the UK and overseas providers that offer services to UK users.
If you are a contractor using exchanges or online wallets to buy, sell, swap or receive crypto, your activity is likely to fall within scope.
What information is shared with HMRC?
Crypto platforms are now required to collect and report a range of personal and transactional details, including:
- Basic identity information such as name, address, date of birth and tax residency
- Transaction data covering purchases, disposals, swaps and transfers
- Information needed to identify gains, losses and income
This data is passed directly to HMRC, allowing it to compare reported crypto activity with Self Assessment returns.
Why HMRC is focusing on crypto now
HMRC has always been clear that crypto is not tax-free. Capital Gains Tax can arise when crypto is sold or exchanged and Income Tax may apply where crypto is earned through activities such as staking, mining or payment for services.
Historically, enforcement has been difficult. Crypto’s decentralised nature and inconsistent reporting by platforms made it harder for HMRC to see the full picture.
The new reporting framework closes that gap. It gives HMRC far greater visibility and reduces the risk of accidental or deliberate under-reporting.
You should now assume HMRC can now see your exchange-based activity, which makes accurate record-keeping more important than ever.
Transaction histories, acquisition costs, disposals and income streams all need to be properly tracked and reported.
This is particularly relevant for contractors who:
- Use multiple platforms or wallets
- Regularly swap between different crypto assets
- Earn crypto alongside traditional contract income
Crypto tax can be more complex than it looks
Crypto taxation is rarely as simple as total sales minus total purchases. Different rules can apply depending on whether an asset is treated as capital or income, how pools are calculated and how specific transactions are structured.
For contractors juggling contract work alongside crypto investments, professional support can be helpful.
An adviser who understands both tax rules and how crypto platforms actually work can help ensure:
- Gains and losses are calculated correctly
- Disclosures are complete and consistent
- Returns align with HMRC’s expectations
The new rules do not require individuals to give HMRC access to private keys or wallet passwords.
However, there are still legal responsibilities. Providing inaccurate personal information to a platform or failing to declare taxable gains or income can result in penalties, interest and further HMRC scrutiny.
Deliberate concealment carries much more serious consequences.
How you can prepare
Crypto may still feel innovative and fast-moving, but from a tax perspective it is now firmly part of the established system.
For contractors, the sensible approach is not to panic, but to prepare. Keep good records, understand where tax may arise and seek advice where transactions become complex.
As HMRC’s visibility increases, clarity and accuracy are the best ways to stay compliant and confident.
