Yes — in the UK, Bitcoin is treated as a capital asset and gains are subject to Capital Gains Tax (CGT). You only pay on gains above your annual CGT allowance (£3,000 for 2024/25). Use the CGT field in the advanced section to estimate your tax liability, or use a tool like Koinly to calculate and file your crypto taxes automatically.
