Greece Slaps 10% Tax on Crypto Gains, 15% Levy on DeFi Income

Greece has approved a 10% tax on cryptocurrency gains alongside a 15% levy on income derived from decentralized finance (DeFi), according to a CoinDesk report, extending the country's tax framework to digital-asset activity. Under the measure, investors will have 12 months to declare past crypto gains without facing late-filing penalties.

The two-tier structure distinguishes between capital appreciation on crypto holdings, taxed at 10%, and DeFi-generated income, taxed at a higher 15% rate. The 12-month amnesty window is designed to encourage holders to bring previously undeclared gains into the tax system without punitive late-filing charges, though the report did not specify a start date or revenue projections for the measure.

Key details remain unresolved, particularly how crypto-to-crypto swaps will be treated — a critical question for investors who routinely move between digital assets without converting to fiat currency. The lack of clarity on swap treatment could complicate compliance and shape investor behavior in the Greek market. Further guidance from Greek authorities is expected as the regime takes effect.
