Crypto tax in Greece: confirmed rules, open questions and filing evidence

Greece does not currently provide a single AADE rule that automatically assigns every spot-crypto gain to a 15% tax rate or a dedicated E1 crypto code. Article 42 of the Income Tax Code expressly covers specified securities and financial derivatives; the 2025 E1 instructions likewise describe securities, not an all-purpose cryptocurrency box. Spot coins, business trading, mining, staking, derivatives and NFTs must therefore be separated. A defensible report documents the numbers and shows which legal classification still requires confirmation.

Short answer: 15% is not a confirmed blanket spot-crypto rate

AADE’s public income-tax overview states that income from the transfer of capital under the applicable category is taxed at 15%. Its examples include shares, partnership interests, government and corporate bonds and financial derivatives. Article 42 of Law 4172/2013 defines the securities that enter that capital-gain category.

Ordinary spot cryptocurrency is not expressly named in the Article 42 list shown in the official AADE legal library, and the current E1 instructions do not create a general “all crypto gains” box. It is therefore unsafe to write that Greece enacted a dedicated 15% crypto regime under Article 42A or that every BTC sale automatically goes to codes 865/866.

What Articles 42 and 42A actually cover

Article 42 covers gains from transferring the listed securities when the income is not business activity. The official text names:

• shares in listed or unlisted companies;
• interests in partnerships;
• government bills and bonds or corporate bonds;
• financial derivative products;
• the transfer of an entire business, subject to the statutory conditions.

The derivative definition includes options, futures, swaps and forwards linked to securities or other assets, exchange rates, interest rates and returns. A crypto futures contract can therefore require an Article 42 analysis based on the actual legal contract. A perpetual position marketed by an offshore exchange should not be assigned automatically merely because the platform calls it “futures.”

Article 42A is not a general crypto provision. It addresses specified employee-share benefits and related qualifying arrangements. Referring to Article 42A as the legal source for a flat tax on all cryptocurrency gains is incorrect.

If a crypto asset is legally a security, company interest or derivative named by Article 42, the capital-transfer rules may apply. If it is an ordinary payment or utility token, the statutory path is less explicit. The token’s rights and the taxpayer’s activity matter more than the ticker.

What the 2025 E1 instructions prove—and what they do not

AADE published the 2025 individual income-tax return and instructions in March 2026. The instructions describe the existing income categories and E1 codes. Codes 865/866 relate to gains from transferring foreign securities within Articles 42 and 42A under the stated conditions. They are not described as universal positive/negative cryptocurrency boxes.

The numbering also should not be guessed from translated blog posts. In Greek forms, paired codes often distinguish the taxpayer and spouse, while different lines handle losses or foreign tax. Use the final E1 instructions and the taxpayer’s confirmed category rather than writing a crypto amount into a code because another website repeated it.

A tax workpaper can still provide annual summaries and transaction schedules. Final E1 mapping should be made after the legal basis is documented, particularly for material amounts.

Private investor, systematic trader or business activity

Greek income-tax treatment distinguishes capital-transfer income from business activity. The Article 42 text itself applies when the result does not constitute business activity. Frequent, organized and profit-directed dealing can therefore require analysis under the business-income rules even if the assets are held by an individual.

No single trade-count threshold in the cited AADE material turns a person into a business automatically. Relevant evidence can include continuity, organization, services to others, commercial infrastructure, financing, accounting records and the overall pattern. A user should select the actual activity profile rather than the lowest desired tax rate.

AADE also explains that sole business activity can be subject to the minimum imputed-income provisions in Articles 28A–28D. This is another reason not to offer “business” as a tax-planning choice without real facts.

Spot sales, swaps, income, DeFi, NFTs and derivatives

Even where the final legal category is open, the software should capture the economic event accurately:

• Sale for euros: record asset, units, proceeds, original cost and fees.
• Crypto-to-crypto swap: record both legs and EUR market value; whether it is a taxable realization needs the confirmed Greek position.
• Mining or staking: separate receipt value from later disposal; do not call the reward a capital gain without analysis.
• Liquidity pool or lending: preserve assets surrendered, receipt tokens, contractual claim, rewards and exit.
• NFT: distinguish collector, creator, commercial sale and tokenized legal rights.
• Derivative close P&L: preserve contract, venue and settlement; open orders and snapshots are not realized profit.

The Greece staking and DeFi guide explains the evidence for open classifications. Losses should not be netted across categories until the applicable legal rule is confirmed; see the Greece loss guide.

How a defensible Greece crypto report should work

1. Import all exchanges, wallets and opening balances.
2. Match own-wallet transfers and preserve original cost.
3. Translate every amount to EUR using a consistent, documented price source.
4. Calculate each disposal without inventing zero basis.
5. Separate spot, income-like events, business activity, derivatives and DeFi review items.
6. Disclose the lot convention used; do not call FIFO an AADE mandate without authority.
7. Show confirmed form mapping separately from unresolved classification.
8. Retain CSV files, transaction hashes, invoices, contracts and valuation evidence.

A summary labelled “15% tax due” is not appropriate where the classification is not established. A better output has a technical result, a possible legal category, a confidence or confirmation status and the evidence still needed. Missing acquisition cost should appear as “not computable,” not 0.00.

For cross-country differences, use the Greece–Germany–Portugal–Spain comparison; a method valid in Germany or Spain must not be imported into Greece automatically.

DAC8 and CARF improve visibility, not legal certainty

Greece transposed the EU DAC8 crypto-asset reporting framework in Law 5301/2026 and also implemented the multilateral CARF exchange framework. Reporting providers collect customer and transaction information under due-diligence rules. The first reports for 2026 data are exchanged in 2027 under the applicable timetable.

Those reports do not calculate the taxpayer’s final Greek income tax. They can contain aggregate acquisition and disposal information without the taxpayer’s complete external-wallet basis. The taxpayer therefore must reconcile provider data with their own records. Read the Greece DAC8/CARF guide for the reporting scope.
