Past crypto gains and AADE: what Greece’s tax bill proposes

The bill tabled in the Greek Parliament on October 26, 2026, proposes voluntary reporting of past crypto gains by individuals, with a 10% capital gains tax and a deadline of twelve months from the law’s entry into force. On November 4, 2026, it is scheduled for debate and a vote, with no confirmed passage or publication in the Government Gazette (FEK): we are describing proposals, not rules already in force.

What are the crypto tax rules in Greece today?

The lack of a clear dedicated framework does not mean that all past crypto income was tax-free. How it is treated depends on the facts and on existing legislation.

In decision 2407/2026 of the Dispute Resolution Directorate, an amount of €620,323 attributed to a Bitcoin transfer was not accepted under code 659 of Form E1 as exempt or specially taxed income. It is a decision on a specific case, not a general rule for every transaction.

The bill’s path up to the check made on November 4 is as follows:

1. October 7, 2026 The Ministry of National Economy and Finance published the draft for public consultation.
2. October 26, 2026 The bill was tabled in Parliament.
3. November 4, 2026 Debate and a vote were scheduled. Completion of the legislative process has not been confirmed.

We use the article numbering of the bill as tabled. Earlier reports of a 15% rate applied retroactively from 2025 referred to a previous draft.

Who does the reporting of past gains apply to?

Article 49 covers individuals with past capital gains from transfers or income from crypto lending, liquidity provision, yield farming, staking and block creation through forging.

TaxHeaven’s analysis, reading the provision together with the transitional clause, takes the view that transactions up to December 31, 2026, are covered. This needs to be confirmed in the final text and in AADE’s (Greece’s Independent Authority for Public Revenue) implementing decision.

There is no equivalent special procedure for companies. Neither the 10% rate nor the €500 threshold automatically carries over to businesses, which assess revenue, expenses and valuations under their own tax and accounting rules.

How much tax is proposed on past crypto gains?

The proposed taxation separates capital gains from transfers from yields treated as interest.

Did you buy crypto for €30,000 and sell it in 2025 for €40,000? With a documented cost basis, no other relevant transactions and provided the provision is passed as drafted, the €10,000 gain means €1,000 in tax.

The proposal is for the return to be filed within twelve months of the law’s entry into force and for the tax to be paid in a lump sum within 60 days of filing. A specific deadline date cannot be calculated yet.

Paying on time is linked to exemption from the Tax Procedure Code’s penalties and interest for the original omission. There is, however, an ambiguity in the wording: while past staking yields are included, the operative provisions on reporting and exemption refer specifically to capital gains from transfers. Whether the same procedural protection applies to every reward needs clarification.

What counts toward covering deemed-income presumptions?

Article 49(4) recognizes, through the special procedure, the reported gain and the eligible reported yields for covering the deemed-income presumptions (“tekmiria”) of Articles 31–32, not the cost of purchase being returned to you.

In the previous example, the €10,000 gain counts, not the €30,000 of initial capital. That doesn’t turn the capital into taxable income. It means the special scheme doesn’t recognize it for this purpose and that AADE can investigate where it came from.

Paying the tax does not rule out an audit and is not a general amnesty on the source of funds.

How are capital gains calculated and what changes from 2027?

Articles 48 and 50 propose a new Article 42B in Law 4172/2013 and a 10% rate in Article 43, applying mainly from tax year 2027. According to the explanatory memorandum, the tax definition of crypto-assets is not limited to those regulated by MiCA.

Purchase cost and the €500 threshold

The gain is the transfer value minus the acquisition cost, including direct expenses. For successive purchases an average acquisition price applies, while if the cost cannot be determined it is deemed to be zero.

An annual net gain of up to €500 is exempt. Above that threshold, the whole gain is taxed: at €600 the tax is €60, not €10. An annual loss exceeding €500 is carried forward for five years, only against future gains from crypto transfers. A loss of exactly €500 is not covered by this wording.

A €4,000 purchase and a €10,000 sale give an indicative tax of €600. With no determinable cost, the tax becomes €1,000. Records from service providers and data from the distributed ledger can support the values.

For the average price, two purchases of 0.5 BTC with total costs of €30,100 and €40,100 give a cost of €70,200 per BTC. Selling 0.4 BTC for €32,000, with an €80 fee, gives an indicative gain of €3,840 and tax of €384. The exact treatment of transfer costs needs implementing guidance.

Staking, mining and crypto-to-crypto swaps

Article 47 treats the related yields as interest, valued at the time of the transaction. A staking reward worth €1,000 implies an indicative tax of €150. Selling it later for €1,600 creates a gain of €600 and tax of €60, provided the annual conditions are met.

For non-business mining, the explanatory memorandum provides for no taxation on creation or receipt and a zero cost basis on transfer. There is no standalone explicit mining rule in Article 42B. For crypto-to-crypto swaps, the stated intention is not to tax them, but the legislative text and cost-basis tracking need clarification.

Purchases, frequent trading and other changes

A taxable transfer can occur without a bank withdrawal, such as when buying goods or contributing to a company’s capital. Article 46 adds crypto purchases to the deemed-income presumptions on acquisitions from 2027.

Article 45 exempts these crypto-assets from the automatic presumption of systematic activity based on three similar transactions within six months. It doesn’t classify every genuine business as private investment.

Article 44 values crypto employee benefits in euros at the time of the transaction. Articles 51–53 govern inheritances and gifts, with a tax liability from January 1, 2027, as intangible movable property located abroad and valued at the previous day’s price. Corresponding cost bases are provided for, while Articles 54 and 57 propose exemptions from the digital transaction fee and, for the specified earlier period, from stamp duty.

What do you report to AADE and under which codes?

No confirmed dedicated form, online process or code has been set for the Article 49 procedure. An AADE decision is expected.

1. Gather your history of purchases, sales, rewards, fees and transfers.
2. Reconcile exchanges, personal wallets and bank transactions.
3. Work with an accountant to separate capital gains, yields and business activity.
4. Check the final law and guidance before choosing to report and pay.

Form E1 is for individuals, Form E3 for business activity where required, and Form N for companies. Decisions A.1062/2026, published on March 9, 2026, and A.1048/2026 concern the corresponding 2025 tax returns, not the special procedure.

Codes 659, 865–866, 781–782 and 743–744 are not a confirmed solution for crypto. Nor are the July 24 and July 31, 2026, deadlines of decision A.1140/13-07-2026, for the corresponding 2025 returns, deadlines under the proposed scheme.

Points to note

• A foreign exchange doesn’t make you invisible to the tax authority. DAC8, Directive (EU) 2023/2226, was transposed by Law 5301/2026, Government Gazette (FEK) A’ 74/15.05.2026, in particular Articles 8 and 22, and communicated by circular O.3023/28.05.2026.
• The first reporting year is 2026, and the first exchanges of information between authorities are expected by September 30, 2027. This is not a filing deadline, nor proof of a full history for previous years. Law 5273/2026 also ratified the OECD’s CARF agreement.
• MiCA, Regulation (EU) 2023/1114, has applied in full since December 30, 2024, with Greek supervisory measures in Law 5193/2025. It does not set income tax.
• Regulation (EU) 2024/1624 generally applies from July 10, 2027. Article 40 concerns risk checks on self-hosted addresses, separate from the tax return.
• VAT is examined separately: the Hedqvist ruling, C-264/14, exempts exchanging Bitcoin for fiat currency, not every service or purchase made with crypto.
• Clarifications are still pending on amounts already reported, audits, lost records, airdrops, forks, tax residence and foreign tax credits.

Our take

We see it as positive that a specific procedure is being proposed, but we wouldn’t call it “wiping the slate clean.” It takes supporting evidence, a final law and implementing guidance. This article is not tax advice; your own case needs an accountant.
