Koinly

Koinly is a web-based crypto tax software. It connects to exchanges and blockchain wallets, collects your transaction history and calculates capital gains, losses and income. It also has a portfolio tracker and a tax loss harvesting view.

It is made for people who traded on several exchanges or used DeFi, staking or liquidity pools and have messy records. It also suits users who want a report to give to an accountant or import into tax filing software. Tax rules differ by country, so users must follow the laws of their own country. The tool does not replace professional advice.

1. Create an account on the Koinly website.
2. Add your exchange accounts using API or CSV files.
3. Connect your blockchain wallets using public addresses.
4. Check your transfers and any items flagged, such as missing cost basis.
5. Preview your capital gains for a tax year.
6. Generate the report you need, such as a complete tax report, Form 8949 or a file for TurboTax.

Use it when:

• You used many exchanges and wallets and want one place for your history.
• You took part in DeFi, staking or liquidity pools.
• You received a 1099-DA and want to check it against your full history.
• You want a report to share with an accountant.

Not ideal if:

• You expect it to replace professional tax advice.
• You need a full report for free, because the free option is a preview of your gains.
