Crypto Tax Basics: What EU Investors Need to Know
Tax rules for crypto vary across EU member states. These three principles apply broadly, but always verify the specifics with your local tax authority or a qualified advisor.
Trading crypto is a taxable disposal
In most EU countries, every sale, swap or closing of a margin or derivatives position is a taxable event. Capital gains tax applies to the difference between what you paid (cost basis) and what you received. Transfers between your own wallets do not trigger tax.
Lending income is taxable
When you receive Bitfinex lending rewards or margin funding income, that income is typically taxable at the point of receipt, based on the market value at that time. The later sale of those assets is treated as a separate capital gain.
Records are your responsibility
EU crypto exchanges are required under DAC8 to report transaction data to national tax authorities from 2026. Accurate records remain your responsibility. CoinTracking maintains a complete, dated audit trail of every Bitfinex transaction — including margin PnL, funding fees and lending payouts.

How to Calculate Your Bitfinex Taxes
Bitfinex users often combine spot trading with active margin positions, derivatives and peer-to-peer lending — each of which has different tax treatment across jurisdictions. Spot disposals generate capital gains; margin PnL is treated as a gain or loss; lending income is taxed at receipt.
The core calculation is: take what you received (proceeds), subtract what you paid (cost basis, calculated with FIFO), and the result is your taxable gain or loss. For lending income, the taxable amount is the market value at the time of receipt.
CoinTracking automates this across your full Bitfinex history and produces a report your accountant or local tax authority will accept.
