How this calculator works

This calculator uses a simplified CGT formula: it calculates your gross gain from the difference between sell and buy values, deducts the annual CGT allowance for your jurisdiction, then applies the appropriate tax rate to give an estimated liability. All logic is deterministic and based on the inputs you provide — no data is stored or transmitted.

Understanding crypto capital gains tax

Most countries treat cryptocurrency as a capital asset rather than currency. This means every disposal — selling, swapping one crypto for another, or spending crypto — is potentially a taxable event. Your gain is the difference between what you paid (cost basis) and what you received (proceeds). Each jurisdiction has different allowances, rates and reporting requirements. This tool gives a rough estimate — for accurate reporting always use dedicated tax software or a qualified accountant.

Frequently asked questions

Do I pay tax on crypto gains?
In most jurisdictions yes — selling, swapping or spending crypto is typically a taxable disposal subject to capital gains tax.
How is crypto capital gains tax calculated?
(Sell Price - Buy Price) × Quantity = Gross Gain. Subtract annual allowance = Taxable Gain. Multiply by CGT rate = Estimated Tax.
What is the crypto CGT allowance in the UK?
£3,000 for 2024/25. Gains below this in a tax year are not subject to CGT. Tax year runs 6 April to 5 April.
What happens if I make a crypto loss?
Capital losses can typically be offset against gains in the same tax year, reducing your CGT liability.
Is this a real tax calculation?
No — this is an educational estimate using simplified rules. Always consult a qualified tax professional for your actual liability.
