What Koinly Does

Koinly connects to your crypto exchanges and wallets via API or CSV import, then automatically calculates your capital gains and losses for the tax year. For UK users, it applies HMRC's specific crypto tax rules — including Section 104 pooling, the 30-day same-day rule, and bed and breakfasting rules — so you don't have to do the maths manually.

The output is a Capital Gains Summary report and a full Transaction History report. You or your accountant use these to complete the capital gains section of your self-assessment tax return. Koinly does not file with HMRC directly.

⚠️ Important for UK Users

HMRC treats cryptocurrency as a capital asset. You are legally required to report gains above the annual CGT allowance (£3,000 for 2024/25) on your self-assessment tax return. Koinly helps you calculate this — but the responsibility to file correctly sits with you. For holdings above £10,000 or complex DeFi activity, use a qualified UK crypto tax accountant alongside Koinly. See HMRC's cryptoassets guidance.
