The rules go considerably beyond setting a headline tax rate. They establish how cost basis is calculated, exempt crypto-to-crypto exchanges from immediate capital-gains taxation and create separate 10% treatment for returns generated through staking, lending and liquidity provision.
When Would Greek Crypto Investors Actually Owe Tax?
For individuals, taxable gains would generally equal the difference between the acquisition price and disposal price of a crypto asset. Where investors have accumulated the same asset through multiple purchases, the legislation provides for an average acquisition price to determine the cost basis.
The first €500 of annual capital gains would be exempt. Above that threshold, qualifying gains would face the proposed 10% rate.
One of the most important provisions for active traders is the treatment of crypto-to-crypto transactions. Swapping one crypto asset for another would not create a taxable capital gain at the time of the exchange.
That means moving from Bitcoin into Ether, for example, would not itself trigger the proposed tax. Tax recognition would instead be deferred until a transaction covered by the disposal rules occurs.
Investor Takeaway
The crypto-to-crypto exemption reduces tax friction for active traders, while the 10% rate gives investors a clearer cost for ultimately realizing gains.
Staking and Crypto Lending Get Their Own 10% Rate
The bill also addresses income that does not come from simply buying and selling tokens. Returns generated through crypto lending, supplying liquidity and locking assets in transaction-validation mechanisms such as staking would be taxed as interest at 10%.
That distinction gives Greece an explicit framework for DeFi and staking income rather than leaving taxpayers to determine whether those rewards should be treated as capital gains, investment income or another category.
The proposal also establishes valuation rules for crypto assets received as benefits in kind by employees, partners or shareholders. Their taxable value would be based on their euro value when received.
Crypto purchases would additionally count as expenditure on acquiring assets for Greece’s tax-assessment rules, while the sale of crypto would not attract the country’s Digital Transaction Fee.
Why Does DAC8 Change the Enforcement Equation?
Greece has historically faced a basic enforcement problem: officials say most domestic crypto investors use platforms based outside the country, making the size of the market difficult to estimate. The government has consequently provided no revenue forecast for the new tax.
That information gap is beginning to narrow.
The European Union’s DAC8 tax-reporting regime took effect on January 1, 2026, requiring covered crypto service providers to collect transaction and identification data for EU-resident customers. The first DAC8 reporting period covers transactions conducted during 2026, with information due to tax authorities in 2027 and subsequently exchanged between EU member states.
Greece is also becoming more integrated into the regulated European crypto market. Four Greek-supervised firms recently appeared in the EU’s MiCA register, including Piraeus Bank, giving domestic regulators a growing pool of locally supervised crypto businesses.
Investor Takeaway
The 10% rate is only half the change. DAC8 makes cross-border exchange activity increasingly visible to Greek tax authorities from the 2026 reporting year onward.
How Does Greece Compare With Other European Crypto Tax Systems?
The proposal reinforces how fragmented crypto taxation remains across Europe despite the introduction of common regulatory rules under MiCA. The EU regulates crypto businesses at bloc level but does not impose a single capital-gains tax model on investors.
National approaches therefore vary considerably. The Netherlands, for example, currently taxes crypto under its Box 3 wealth regime rather than imposing a straightforward tax on realized trading gains. Dutch investors face tax based on a deemed return on qualifying assets, illustrating how two EU residents can face materially different tax treatment for economically similar crypto portfolios.
Greece is also offering a transition mechanism for investors with previously undeclared activity. The draft would allow taxpayers to voluntarily declare gains from earlier crypto disposals within 12 months after the law is published, subject to the specified conditions, without penalties or interest.
The government plans to complete consultation on October 22 and aims to have the legislation passed during the first week of November. If approved, the result would replace Greece’s existing tax ambiguity with a comparatively simple structure: a 10% rate on taxable disposal gains, a €500 annual exemption, no immediate tax on crypto-to-crypto swaps and explicit taxation of staking and other yield-generating activity.
