Koinly is the most comprehensive crypto tax platform available in 2026 and the clear choice for traders outside the US who need international tax report support. Founded in 2018, it connects to over 700 exchanges, wallets, and blockchains via API or CSV import, automatically categorises every transaction type — trades, staking rewards, airdrops, DeFi interactions, NFT sales — and generates tax reports compliant with the specific rules of over 20 countries.

The platform’s smart transaction matching algorithm automatically identifies transfers between your own wallets and excludes them from taxable events — significantly reducing the complexity of portfolios spread across multiple exchanges and wallets. Koinly supports multiple accounting methods including FIFO, LIFO, HIFO, and the UK’s Section 104 pooling method, automatically applying the correct method for your country.
