By Greece Approves 10% Crypto Gains Tax, 15% on Staking and DeFi Income
Greece’s parliament approved a new cryptocurrency tax framework on November 5, introducing a 10% capital gains tax for individuals and a separate 15% levy on returns from staking, crypto lending and decentralized finance (DeFi). The legislation establishes the country’s first comprehensive tax regime for digital assets, with the main provisions applying from January 1, 2027.
The framework follows a proposal published by the Ministry of National Economy and Finance in October. Greece’s original proposal included a 10% tax on realized gains and a €500 annual exemption, alongside separate treatment for income generated through crypto-related activities.
The approved bill also introduces rules for calculating acquisition costs, carrying forward investment losses and declaring previously earned cryptocurrency income. However, questions remain over the treatment of crypto-to-crypto transactions, despite the Finance Ministry’s stated intention to exempt them.
How Will Greece’s 10% Crypto Tax Work?
Individuals will pay a flat 10% tax on annual net capital gains from transferring cryptocurrency. Gains of up to €500 per tax year are exempt. If net gains exceed that threshold, the entire amount becomes taxable, rather than only the portion above €500.
The legislation defines taxable transfers to include exchanging cryptocurrency for fiat currency, using digital assets to purchase goods or services, and contributing crypto assets toward corporate or share capital.
For purchases made in several installments, the acquisition cost will generally be calculated using the average purchase price. Transaction costs directly associated with acquiring or transferring assets are also included in the calculation. Investors can substantiate their acquisition and disposal prices using exchange records, intermediary documentation or information obtained directly from distributed ledgers.
Annual crypto losses exceeding €500 can be carried forward for five years, but they can only offset future gains from cryptocurrency transfers. They cannot be used to reduce unrelated investment income or other capital gains.
Investor Takeaway
The €500 exemption creates a threshold effect: investors exceeding it face tax on their entire annual net gain, making accurate cost-basis records particularly important.
Why Are Crypto-to-Crypto Swaps Still a Concern?
One of the most important questions concerns whether exchanging one cryptocurrency for another could trigger a taxable event.
The Finance Ministry says crypto-to-crypto swaps will not generate taxable capital gains. Under that interpretation, exchanging Bitcoin for Ether would not create an immediate tax liability, with taxation deferred until a subsequent taxable disposal.
However, Parliament’s Scientific Service identified a potential drafting problem in the legislation. The bill defines taxable transfers to include not only exchanges for money and purchases of goods or services, but also any disposal of cryptocurrency for consideration.
The Scientific Service warned that this broader wording could encompass exchanges between different cryptocurrencies. It recommended introducing an explicit exemption for crypto-to-crypto swaps, potentially with additional clarification covering conversions between stablecoins and other digital assets.
The distinction matters for active traders and investors who regularly rotate between tokens without converting their holdings into traditional currencies. If the wording is interpreted broadly, transactions that the Finance Ministry intends to exempt could face uncertainty over their tax treatment.
Parliament approved the bill on November 5, but its legislative listing still showed the approved text awaiting publication in the Government Gazette. The final published wording and subsequent tax-administration guidance will therefore be important in resolving the issue.
How Will Staking and DeFi Income Be Taxed?
Greece will treat returns from cryptocurrency lending, liquidity provision and staking as interest income, subject to a separate 15% tax rate.
The provisions also cover yield farming and returns generated through decentralized protocols. This gives the authorities a specific classification for income earned by committing digital assets to lending arrangements, liquidity mechanisms and transaction-validation systems.
Where rewards are paid in cryptocurrency rather than euros, their value will be calculated at the time of the transaction. The amount already subjected to the 15% tax will subsequently count as the acquisition cost of those tokens, preventing the same income from being taxed again when the assets are sold.
The separate treatment is important because staking and liquidity returns do not necessarily involve selling an underlying investment. By classifying them as interest, Greece establishes a tax obligation when the income is received rather than waiting for the investor to convert the rewards into fiat currency.
Investor Takeaway
The 15% interest classification extends the tax framework beyond realized trading profits, bringing staking, lending and DeFi yields into a defined income category.
What Happens to Cryptocurrency Gains Made Before 2027?
The legislation provides a 12-month voluntary disclosure window for individuals wishing to declare cryptocurrency income earned before the new provisions take effect. Qualifying declarations will not attract late-filing fines or interest, provided the applicable tax is paid within 60 days of submission.
The arrangement covers previously earned capital gains as well as income from activities such as lending, liquidity provision and staking. The tax authority will establish the required declaration procedures and supporting documentation.
However, voluntary disclosure does not automatically establish the legitimate origin of the funds used to acquire cryptocurrency. The tax administration retains its authority to examine acquisition costs, supporting records and the origin of invested capital.
The government has also acknowledged difficulties estimating potential tax revenue because many Greek cryptocurrency investors use overseas platforms. That creates an additional implementation challenge as authorities seek to establish reliable transaction histories and verify declared gains.
The international reporting environment is also changing. The OECD’s Crypto-Asset Reporting Framework is expanding the collection and exchange of cryptocurrency transaction information between participating tax authorities, adding another layer of visibility into cross-border digital asset activity.
For Greece, the new framework provides a defined starting point for taxing private cryptocurrency investments. Its practical impact will depend on how authorities resolve the swap provisions, implement documentation requirements and apply the new rules to investors using both domestic and overseas platforms.
