Crypto CGT Calculator is a free UK crypto Capital Gains Tax calculator that applies HMRC's actual matching rules — the same-day rule, the 30-day bed-and-breakfast rule, and Section 104 pooling — across tax years 2024/25 to 2026/27, including the 30 October 2024 rate change.
Unlike black-box tools, it shows the complete working for every disposal: which rule matched, the cost basis used, and how the gain lands in your tax bands. Everything runs in your browser — no signup, no wallet connection, and your transactions never leave your device. CSV import supports Coinbase, Kraken and Binance. With HMRC now receiving exchange data under the Cryptoasset Reporting Framework (CARF), it's built for UK investors who need to check what they owe before the 31 January Self Assessment deadline.
Really useful tool for anyone dealing with HMRC's matching rules. One thing that would make it even better is a CSV export of the full transaction breakdown matched against each pool, so the figures line up cleanly when pasting into my self-assessment.
How does it handle transfers between my own wallets, do I need to mark those as non-taxable events somewhere or does it figure that out automatically from the wallet labels?
