UK Crypto Capital Gains Calculator
Estimates your CGT liability using HMRC rules for 2024/25. £3,000 annual exempt amount · 18% basic rate · 24% higher rate.
How UK Crypto Tax Works
HMRC treats cryptocurrency as a capital asset. When you sell, swap, or spend crypto, you trigger a disposal. The gain (or loss) is the difference between what you received and your original cost basis.
For 2024/25, you can make up to £3,000 in gains tax-free. Above that, basic rate taxpayers pay 18% and higher rate taxpayers pay 24%.
What This Calculator Does Not Cover
This tool uses a simplified average cost method. HMRC actually requires Section 104 pooling, the same-day rule, and the 30-day bed & breakfasting rule. For a fully compliant report you can submit to HMRC, use Koinly — it imports from every major exchange and generates the exact figures your accountant or self-assessment needs.
