In short:

Koinly is crypto tax software that imports trades from exchanges and wallets and calculates capital gains.
It supports FIFO, LIFO, average cost and other methods used in major markets.
Import and preview are free. You pay only when you download a tax report.

What Koinly is

Koinly connects your exchanges and wallets (API, CSV or wallet address), fetches historical prices, matches transfers between your own wallets, and calculates gains and losses for each disposal.

Main features

Import via exchange API, CSV, EVM auto-sync, Solana, Cardano and more
Smart transfer matching so wallet-to-wallet moves are not treated as sales
Cost basis methods including FIFO, LIFO and average cost
Mining, staking, lending, airdrops, DeFi and NFTs
Balance checks and negative-balance warnings
International tax reports

How it helps with taxes

Rules differ by country. Koinly supports reports for many jurisdictions and common cost-basis methods. Always cross-check against your tax authority’s guidance.

Typical workflow:

Import all accounts and wallets into Koinly.
Choose your country and the cost-basis method that matches your rules.
Review unmatched transfers and balances.
Preview gains, then download the report you need for your tax filing.
You remain responsible for the figures you declare.
