Calculate UK Capital Gains Tax (CGT) and Income Tax on cryptocurrency transactions. Estimate your crypto tax liability for trading, mining, and staking.
A UK crypto tax calculator computes Capital Gains Tax (CGT) on cryptocurrency disposals based on HMRC regulations. Calculates taxable gains after applying the annual CGT allowance (£3,000 for 2024/25), applies correct tax rates (10% basic rate, 20% higher rate), and accounts for same-day and bed-and-breakfasting rules unique to UK crypto taxation. Handles complex scenarios like crypto-to-crypto trades, staking rewards, mining income, and DeFi transactions. Essential for UK crypto investors completing Self Assessment tax returns, avoiding HMRC penalties, and optimizing CGT through allowance management and strategic disposal timing.
Ensure complete HMRC compliance and avoid penalties up to 100% of unpaid tax plus interest by accurately calculating CGT on all crypto disposals—HMRC actively pursues crypto tax evasion. Maximize your tax-free allowance strategically by timing disposals to use the full £3,000 annual exemption without waste. Understand same-day and 30-day bed-and-breakfasting rules that can significantly affect your cost basis and tax liability—many investors miscalculate by ignoring these complex rules. Save thousands in professional accounting fees by generating compliant tax calculations and reports yourself. Optimize tax efficiency through loss harvesting, utilizing spouse allowances, and timing disposals across tax years. Used by UK crypto traders, accountants, and investors managing portfolios on exchanges like Binance UK, Coinbase, and Kraken.
Enter all crypto disposals (sales, trades, gifts, spending) including acquisition date, cost, disposal date, and proceeds in GBP. The calculator automatically applies same-day matching rules first, then bed-and-breakfasting (30-day) rules, then pools remaining holdings using Section 104 pooling. Results show total gains, deduct annual allowance, and calculate CGT owed at your applicable rate (10% or 20%). For multiple transactions, import CSV files from UK exchanges. Review detailed calculations showing each disposal, applicable rules, and tax treatment. The calculator helps identify opportunities to use unused allowances or harvest losses before tax year end (April 5th). Export reports for Self Assessment or accountant review.
