⚖️ Core Rules: Rate, Exemption, and Scope

Greece is preparing legislation to impose a 15% capital gains tax on cryptocurrency profits, with a tax-free threshold of €500 per year.[reference:2][reference:3] The new framework is expected to apply retroactively from January 1, 2025.[reference:4][reference:5]

Key Provisions at a Glance

• Tax rate: 15% flat rate on capital gains from cryptocurrency sales.[reference:6][reference:7]
• Annual exemption: First €500 of profits per taxpayer per year is tax-free.[reference:8][reference:9]
• Retroactive application: Rules apply from January 1, 2025.[reference:10][reference:11]
• Inheritance and gifts: Clear framework for inheritances, donations, and parental benefits.[reference:12]
• Crypto-to-crypto swaps: Not considered taxable transactions.[reference:13]

📋 Taxable Events and Common Triggers

Understanding which transactions trigger a capital gains tax liability is essential for compliance.

Transactions That Trigger Capital Gains Tax

• Selling crypto for fiat currency: Profits from selling cryptocurrency for euros or other fiat are taxable.[reference:16][reference:17]
• Using crypto to purchase goods or services: Treated as a disposal, similar to selling.[reference:18][reference:19]
• Swapping one cryptocurrency for another: Note: Under the proposed framework, crypto-to-crypto swaps are not taxable events.[reference:20]

Income Tax Triggers (Not Capital Gains)

Certain crypto-related activities are treated as ordinary income, subject to Greece's progressive income tax rates (9%–44%):[reference:21]

• Mining rewards: Personal mining is not taxed, but corporate mining operations are subject to business tax.[reference:22]
• Staking and lending rewards: Income from staking, DeFi lending, and liquidity provision.[reference:23][reference:24]
• Airdrops: Received tokens are taxed as income at fair market value on receipt.[reference:25][reference:26]
• Payments received in crypto: For goods or services rendered.[reference:27][reference:28]

✅ Non-Taxable and Excluded Transactions

Not all crypto activities trigger a tax event. The following are generally non-taxable:

• Buying crypto with fiat currency: Simply purchasing crypto is not taxable.[reference:29]
• Transferring crypto between wallets you own: Moving assets between your own wallets is not a taxable event.[reference:30]
• Holding crypto: Simply holding assets without selling or disposing of them does not trigger tax.
• Crypto-to-crypto swaps: Under the proposed framework, exchanging one cryptocurrency for another is not taxable.[reference:31]
• Small gifts: Crypto gifts under €800 per year in total are generally exempt.[reference:32]

🧮 How to Calculate Your Taxable Gain

The capital gain is calculated as the difference between the sale price and the purchase price, taking into account directly related costs.[reference:34]

Formula

Capital Gain = Sale Price – (Purchase Price + Directly Related Costs)

What's Included in Cost Basis

• The original purchase price of the cryptocurrency.[reference:35]
• Directly related purchase or sale costs, such as trading fees and network gas fees.[reference:36]

Deducting Losses

Capital losses from crypto transactions can offset gains within the same tax year.[reference:37] Excess losses cannot be carried forward to future years.[reference:38]

Example Calculation

• Purchase price: €10,000
• Purchase fees: €100
• Sale price: €15,000
• Sale fees: €150
• Capital gain = €15,000 – (€10,000 + €100 + €150) = €4,750
• Taxable gain after €500 exemption = €4,250
• Tax due = €4,250 × 15% = €637.50

📁 Documentation and Recordkeeping

Proper documentation is essential for accurate tax reporting and to substantiate your calculations in case of an audit.

What to Record for Each Transaction

• Date of acquisition and disposal
• Amount of cryptocurrency bought or sold (in units)
• Price per unit in euros at the time of transaction
• Total value in euros
• Transaction fees (trading fees, network gas fees, etc.)
• Counterparty or platform used
• Wallet address involved
• Purpose of the transaction (if applicable)

Best Practices

• Export transaction history from exchanges and wallets regularly.
• Use crypto tax software to aggregate data across platforms.
• Keep records for at least five years (the typical statute of limitations for tax audits in Greece).
• Document the euro value of all crypto at the time of receipt (for income tax purposes).

📄 Reporting and Filing Requirements

Crypto gains and income must be reported to the Greek Independent Authority for Public Revenue (AADE) through the Taxisnet platform.

Filing Deadlines

• Tax year: January 1 to December 31[reference:39]
• Filing deadline: June 30 of the following year[reference:40]
• Forms: Individuals report via E1 and E2 forms on the AADE Taxisnet platform.[reference:41]

DAC8 and EU Reporting

Greece has enacted Law No. 5301/2026, implementing the EU DAC8 directive for crypto-asset reporting.[reference:42] Under DAC8:

• Reporting Crypto-Asset Service Providers must collect and submit detailed transaction data to tax authorities.[reference:43]
• Data will be automatically exchanged between EU member states.[reference:44]
• The first reporting period covers the 2026 calendar year.[reference:45]

Use this checklist to ensure you are prepared for the 2025-2026 tax season.

• Review your transaction history: Export all crypto transactions from exchanges and wallets for the tax year.
• Identify taxable events: Separate sales, disposals, and income-generating activities from non-taxable transfers and swaps.
• Calculate cost basis: Determine the purchase price and associated fees for each asset sold.
• Apply the €500 exemption: Deduct the tax-free threshold from your total annual gains.[reference:57]
• Offset losses: Use capital losses to reduce your taxable gains within the same year.[reference:58]

📖 Example Scenario

Let's walk through a practical example to illustrate how the rules apply.

🚫 Common Mistakes to Avoid

Even diligent taxpayers can make errors. Avoid these common pitfalls:

• Assuming crypto-to-crypto swaps are taxable: Under the proposed framework, they are not.[reference:62] However, this could change, so always verify the current rules.
• Forgetting to include fees in cost basis: Trading fees and gas fees are deductible.[reference:63]
• Failing to report income from staking, mining, or airdrops: These are taxed as income, not capital gains.[reference:64]
• Not keeping adequate records: Without proper documentation, you cannot substantiate your cost basis or losses.
• Assuming the €500 exemption applies per transaction: It applies to total annual profits, not per transaction.[reference:65]
• Ignoring DAC8 reporting obligations: From 2026, crypto service providers will report transaction data to tax authorities.[reference:66]
• Relying on outdated information: The law is still pending and may change.[reference:67]

🛡️ Risk Controls and Regulatory Uncertainty

Given the evolving nature of crypto taxation in Greece, proactive risk management is essential.

Key Uncertainties

• Legislative status: The bill has not yet been passed by Parliament.[reference:68] Final details could shift before submission.[reference:69]
• Retroactive application: The rules are expected to apply from January 1, 2025.[reference:70] This means 2025 transactions may be subject to tax even if the law is passed later in 2026.
• Enforcement of offshore transactions: Greek authorities have acknowledged limited visibility into trades on foreign platforms.[reference:71] However, DAC8 will enhance reporting from 2026.[reference:72]
• VAT on crypto services: Some crypto services may be subject to 24% VAT.[reference:73]

Risk Control Measures

• Monitor official sources: Follow announcements from the Greek Ministry of Finance and AADE.
• Maintain comprehensive records: Keep all transaction data for at least five years.
• Consider professional advice: Consult a tax professional with expertise in Greek crypto taxation.
• Set aside funds for potential tax liabilities: Given the retroactive application, be prepared for a tax bill on 2025 gains.
• Stay informed about DAC8: Understand how automatic reporting may affect your privacy and compliance obligations.
