How are Poloniex transactions taxed?

Crypto tax varies depending on where you live and the specific transactions you've made on Poloniex. Learn more about crypto tax in your country in our crypto tax guides, but generally, you’ll pay either Capital Gains Tax or Income Tax on your crypto.

  • Capital Gains Tax: Whenever you sell or swap crypto or NFTs on Poloniex make a gain, you’ll likely pay Capital Gains Tax on that gain. This includes PnL from derivatives.

  • Income Tax: If you earned new tokens on Poloniex, for example through Poloniex Earn, this is generally viewed as additional income and subject to Income Tax upon receipt.

Does Poloniex report to tax offices?

As a large centralized exchange, Poloniex has faced pressure to share data with tax offices. Notably, the IRS issued a John Doe summons to try and compel the exchange to share customer transaction data. Poloniex has since withdrawn operations from the US.

How do I file my Poloniex taxes?

You need to report any capital gains, losses, or income from your Poloniex investments to your tax office and pay any taxes due. This is generally done as part of your annual tax return.

You can calculate this yourself, by identifying each taxable transaction, the kind of tax that applies, and calculating your gains and losses (and any income) - but it's very time-consuming.

This is why most investors opt to use a crypto tax calculator like Koinly. Koinly calculates your tax liability and generates your crypto tax report, ready to file with your tax office.
