📋 Tax Obligations

UK residents must report all cryptocurrency transactions to HMRC. This includes buying, selling, mining, staking, and using crypto for purchases. Failure to report can result in penalties.

  • Capital Gains Tax on profits
  • Income Tax on rewards
  • Self Assessment filing required
  • Records must be kept for 5+ years

💰 Payment Restrictions

Tax payments cannot be made directly from crypto profits. You must convert crypto to fiat currency first, then pay taxes through official HMRC channels. This prevents money laundering and ensures proper tax collection.

Important: Direct crypto-to-tax payments are not accepted by HMRC.

🛡️ Anti-Money Laundering

All crypto transactions are subject to AML regulations. Large transactions may require identity verification. Our calculator helps you stay compliant by accurately calculating your tax liabilities.
