Crypto Exchanges Must Report Customer Data to Tax Authorities from 2026

Crypto investors are facing a change in their tax obligations as new EU rules take effect from 2026. The DAC8 rules require crypto exchanges operating in or serving users from Germany to collect and report customer information, including tax identification details.

This means that authorities will no longer rely solely on investors to declare their crypto activity, but instead will receive information directly from the platforms through which transactions take place.

The implications are significant for investors who have assumed that a pseudonymous blockchain address provides protection from the taxman. However, regulated intermediaries are increasingly attaching names to their customers, making it more difficult to evade taxes.

Crypto exchanges will also face operational burdens as they collect customer information and transmit transaction data to authorities. Investors who fail to provide required details can face penalties of up to €50,000.
