The tax applies to realised gains rather than the full sale value
The taxable amount is the positive difference between the acquisition price and the selling price. Annual cryptocurrency gains of up to 500 euros are exempt under the approved bill.

That distinction matters for users who move large amounts but earn only a small profit. The transaction value and the taxable gain are not the same number, so accurate purchase records become important.
Audit and transparency rules are still to come
A senior finance ministry official said further implementation guidance would be published in the coming weeks. Those instructions are expected to explain reporting, verification and audit procedures.
Many Greek investors use platforms registered outside the country. This makes the size of the domestic market difficult to measure and may complicate enforcement without clear information-sharing rules.
The decision adds another national model inside the EU
The vote took place on 5 November. European Union countries do not use one common tax rate for cryptocurrency gains, and national approaches currently vary widely.
Investors should therefore separate the headline rate from the practical obligations. The final effect will depend on cost-basis rules, required documents and the way foreign exchange accounts are reported.
