The proposal offers an exemption for small gains and a 12-month voluntary declaration window for earlier transactions. It has not yet become law.
Greece has proposed a 10% income tax on individuals’ gains from disposing of crypto assets, with an exemption for annual net gains of up to €500. The draft opened for public consultation on October 7. A purchase cost that cannot be established would be treated as zero.
The Ministry of National Economy and Finance will accept comments until 10 a.m. local time on October 22. It aims to put the crypto regulation proposal to a parliamentary vote in the first week of November. The bill has not yet become law.
The €500 threshold and proof of purchase costs
Under Article 281 of the draft, a gain would be calculated by subtracting acquisition cost from disposal proceeds, including directly related transaction expenses. For assets acquired in successive purchases, total purchase value would be divided by total quantity.
The average purchase cost calculator can be used for that calculation. It gives an average unit cost; it does not calculate Greek tax or apply the proposed exemption.
Acquisition and disposal prices could be supported by documents from a crypto service provider or another intermediary that keeps transaction records. Evidence directly obtainable from the distributed ledger would also be accepted. If the purchase price cannot be established, there would be no acquisition cost to deduct from disposal proceeds.
The €500 threshold would not apply separately to each sale. The exemption covers total net gains for a tax year after the relevant losses are deducted. The draft does not provide an automatic €500 deduction from every annual gain above the threshold.
Annual losses exceeding €500 could be carried forward for the following five years. They could be deducted only from future gains on disposals of crypto assets.
Swaps, staking and past gains
Taxable disposals would include sales for money, purchases of goods or services with crypto, and contributions of crypto to company capital. According to the ministry, crypto-to-crypto exchanges would not generate taxable capital gains.
Article 280 classifies returns from staking, crypto lending and liquidity or yield arrangements in decentralized protocols as interest income. If the return is paid in crypto, its value at the time of the transaction would be used. On a later sale, the asset’s acquisition cost would be the value previously used to calculate interest tax.
The proposed window for declaring past gains would last 12 months from the law taking effect. Individuals who voluntarily file within that period and pay the tax within 60 days of filing would avoid penalties or late-payment interest for the earlier failure to declare. The tax itself would still be payable.
DAC8 reporting is a separate obligation
Under the EU’s DAC8 information-sharing rules, crypto service providers have been collecting data on reportable transactions by EU tax residents since January 1, 2026. Tax authorities have until September 30, 2027 to exchange the first information covering 2026. DAC8 does not set the 10% rate in Greece’s proposal.
