Greece Crypto Tax Guide 2025

Greece introduced specific cryptocurrency taxation in 2021, treating crypto as property subject to capital gains tax. The Greek tax authority (AADE - Independent Authority for Public Revenue) applies a relatively low 15% tax rate on crypto gains, making Greece one of the more favorable European jurisdictions for crypto taxation.

Capital gains from cryptocurrency sales are taxed at a flat rate of 15% (regardless of holding period). This low rate applies to all crypto gains and is significantly more favorable than progressive income tax rates (up to 44%). The 15% rate is the same as other capital gains in Greece, such as stocks and bonds.

Cryptocurrency capital gains are reported on Form E1 (Annual Income Tax Return) under Code 651 (Income from Transfer of Cryptocurrency). You must declare: total sale proceeds for the year, total acquisition costs, and net capital gain. Unlike some countries, Greece allows summary reporting—you don't need to list every transaction individually.

Greece does not currently have a specific tax-free allowance for cryptocurrency capital gains. However, there is a general income tax threshold of €10,000 for annual income. If your only income is crypto gains and they're under €10,000, you may not owe tax. This interpretation is evolving, so consult with a Greek tax advisor for confirmation.

Mining rewards and staking income are treated as business income (επιχειρηματική δραστηριότητα) if done systematically, or miscellaneous income if occasional. Business income is subject to progressive tax rates (9-44%) plus potentially social security contributions. Occasional income is taxed at standard income tax rates. Report on E1 Form under the appropriate income category.

Trading one cryptocurrency for another (e.g., BTC for ETH) is a taxable disposal. You must calculate the gain or loss in EUR at the moment of trade using the fair market value of both cryptocurrencies. This follows the standard EU interpretation that crypto-to-crypto swaps trigger capital gains tax.

Greece does not specifically mandate FIFO or average cost. In practice, FIFO (First In, First Out) is commonly used and recommended for consistency. Taxxy applies FIFO calculations by default for Greek tax purposes, which aligns with international standards and provides audit defensibility.

Capital losses from cryptocurrency can offset capital gains in the same tax year. Net capital losses can potentially be carried forward for up to 5 years to offset future capital gains. However, the carryforward rules for crypto are still evolving in Greek tax law. Consult with a tax professional for current guidance.

Maintain detailed records for at least 5 years: transaction dates, EUR values at transaction time, exchange names, wallet addresses, acquisition costs, sale proceeds, and gain/loss calculations. AADE can request full documentation during audits. As crypto taxation is relatively new in Greece, thorough record-keeping is especially important.

Taxxy automatically generates E1-compliant summary reports with 15% tax calculations, provides EUR valuations using historical ECB exchange rates, applies FIFO cost basis methodology, categorizes capital gains vs. business income, tracks loss carryforwards, and produces audit-ready documentation for AADE compliance.
