Greece sets 10% tax on crypto gains, exempts first €500

The framework calculates gains from the difference between an asset’s acquisition and transfer prices. Where an investor bought crypto in multiple transactions, the calculation uses an average acquisition price. Exchanging one cryptocurrency for another will not trigger a taxable capital gain, according to the Finance Ministry’s consultation announcement. Crypto asset sales are also exempt from the Digital Transaction Fee.

Investors will have 12 months from publication of the law to voluntarily declare gains from earlier transfers. Under specified conditions, those declarations will not incur fines or interest. Greek tax publication Forin reported that disclosure does not establish the legitimacy of the funds originally used to buy the assets. It also said crypto transfers are excluded from the presumption that repeated transactions amount to business activity, while purchases count as asset acquisition expenditure in checks on the origin of funds.

Returns from lending, liquidity provision and staking are treated separately from trading gains. The ministry classifies them as interest subject to a 15% rate. Further directives on transparency and tax audits are expected in the coming weeks, a senior Finance Ministry official said. The government has not estimated the tax’s revenue; the official said most Greek investors use platforms based abroad, making the domestic market difficult to measure.

The measure arrives as EU DAC8 reporting rules require crypto service providers to collect information on EU residents’ transactions from Jan. 1, 2026. Providers must report to national tax authorities, which exchange relevant information with investors’ countries of tax residence. The first exchanges, covering 2026 transactions, are due by Sept. 30, 2027.
