How do I file my Bithumb taxes?

You'll need to calculate and report any income or capital gains you made with your tax office. For most people, this happens as part of your annual tax return.

There are a couple of ways you can do this - do it yourself, by identifying your taxable transactions, calculating your net capital gain or loss, and the fair market value of any crypto income.

Or, use a crypto tax calculator like Koinly to easily calculate your taxable income for you, and generate your crypto tax report, ready to file with your tax office.

Koinly works by importing your crypto transaction data to analyze what's taxable, and what's not.

Koinly lets you manage all your crypto transactions - from all the blockchains, wallets and exchanges you use - from one single platform, making crypto tax simple.
