How is cryptocurrency tax calculated?

Tax is calculated based on the difference between purchase price and sale price, after deducting fees. Capital gains are taxed at 15%. Example: If you bought 1 BTC for €40,000 and sold it for €55,000, the capital gain is €15,000 and the tax is €2,250 (15%).

What's the difference between capital gains tax (15%) and income tax (9-44%)?

Capital gains tax of 15% applies to sales, swaps, and purchases with crypto. Income tax of 9-44% (progressive scale) applies to mining, staking rewards, and airdrops considered income generation.

When do I NOT pay tax?

You don't pay tax when: holding (HODL) crypto in your wallet, transferring between wallets (Exchange ↔ Ledger), buying with fiat (euros). Taxation occurs only when you realize gains (sale/swap).

What is FIFO and does this calculator apply it?

FIFO means the first coins you bought are often treated as sold first. This tool does not apply FIFO automatically — you enter your own total cost basis and proceeds in euros. Use FIFO (or another method your advisor confirms) when consolidating multiple purchases into one disposal total.

Can I offset losses from previous years?

Yes, losses can be carried forward for up to 5 years and offset against future gains. If you have a €2,000 loss from 2024 and €5,000 profit in 2025, the taxable capital gain is €3,000 (5,000 - 2,000).

What codes do I use in E1?

In E1 you use: Code 743 for the amount you spent to buy crypto, Codes 865-866 for capital gain (profit) from sale, Codes 781-782 for capital returning to the bank (to avoid double taxation).

What is MiCA and how does it affect taxation?

MiCA (Markets in Crypto-Assets) is the European regulation integrated from 2025-2026. Crypto is officially treated as investment products. Also, due to DAC8, exchanges are required to share data of Greek users with AADE.

Crypto Tax

What this calculator does

This tool estimates tax from amounts you enter in euros. It does not import exchanges, apply FIFO, or fetch prices. You must convert crypto to EUR at fair value yourself and, for disposals, supply your own cost basis and proceeds totals.

Income from crypto (rewards)

Declare rewards in EUR at the value when received (staking, airdrops, mining, other). We apply a simplified progressive income-tax estimate on the total — real liability depends on your full taxable income.

No income rows yet. Use “Add income” if you received rewards, or skip to disposals below.

Disposal (capital gains)

One aggregated disposal in EUR: your total cost basis vs total proceeds for this scenario. Leave empty if you only want income tax above.

Field Information

* Cost basis and sale proceeds — required to estimate 15% capital gains tax on this disposal.

ℹ Optional fields - Improve calculation accuracy

Total Purchase Amount (€)*

The total amount you paid to purchase cryptocurrencies in euros (including fees). Example: If you bought 1 BTC for €40,000, enter 40,000.

Total Sale Amount (€)*

The total amount you received from the sale in euros (before fees). Example: If you sold 1 BTC for €55,000, enter 55,000.

Exchange Fees (€)

ℹ

Fees you paid to the exchange (optional but recommended). These are deducted from profits before tax calculation.

Disposal type

For your records; 15% applies to net gains from the EUR figures you entered.

Previous Year Losses (€)

ℹ

Losses from previous years that can be offset (up to 5 years). If you have a €2,000 loss from 2024, enter 2000.

How is Tax Calculated?

The basic rule is taxation of capital gains (profits). The calculation is based on the difference between purchase price and sale price, after deducting related expenses (fees). Example: You bought 1 BTC for €40,000 (including fees). You sold it for €55,000. The capital gain is €15,000. Tax (15%): €2,250.

The Two Basic Tax Categories

Depending on the source of income, the tax changes: A. Capital Gains Tax (15%) - Applies to individuals for: Sale of cryptocurrencies for euro or other fiat currency, Swap of one cryptocurrency for another, Purchase of goods/services with cryptocurrencies. B. Income Tax (Progressive Scale 9% - 44%) - Concerns activities considered "income generation": Mining, Staking & Lending (rewards are taxed as income), Airdrops (often treated as gift or other income).

When You DON'T Pay Tax

* Holding (HODL): As long as you keep cryptocurrencies in your wallet, you don't owe tax, even if their value has increased tenfold. * Transfer between wallets: Transfer from Exchange to your Ledger (or vice versa) is not a taxable event. * Purchase with Fiat: Buying cryptocurrencies with euros is not taxed (but must be declared as expense in E1).

Declarations and E1 Form

In the 2026 tax return (for 2025 income), the following codes are typically used: Code 743: Here you declare the amount you spent to purchase cryptocurrencies (documentation coverage). Codes 865-866: Here you declare the capital gain (profit) from the sale. Codes 781-782: Here you can declare the capital returning to the bank (the original investment amount) to avoid double taxation.

Options and Strategies

You have some options to optimize your taxation: 1. Loss Offset: If in one year you have profit from Bitcoin but loss from Ethereum, you can offset them. Losses can be carried forward for 5 years (subject to rules in force). 2. Cost basis records: For multiple purchases, you must determine which lots are sold (e.g. FIFO is common) outside this calculator — keep exchange exports. 3. Stablecoins: Many investors convert profits to USDC/USDT instead of euro; crypto-to-stablecoin swaps are generally taxable disposals under current guidance.

MiCA and New Framework 2025-2026

Cryptocurrency taxation in Greece has entered a new, clearer phase from 2025-2026, with the integration of special provisions and the European MiCA regulation. Now, cryptocurrencies are officially treated as investment products (capital assets) and not just as "intangible titles". Important Note: Due to new transparency rules (DAC8), exchanges (Binance, Kraken, etc.) are now required to share data of Greek users with AADE. Hiding transactions is extremely risky.

Note: Cryptocurrency figures are estimates based on current Greek law and simplified rules. Only the euro amounts you enter are used—no imports, no automatic FIFO or lot matching. Income-tax and 15% capital-gains illustrations are not a full return. Consult a tax advisor for your real position and filing.

Important Notice

Cryptocurrency figures here are estimates based on current Greek tax law and simplified assumptions. The tool only uses euro amounts you type in—it does not import trades, track lots, or apply FIFO automatically. Reward income uses a progressive income-tax illustration on the total EUR you declare; disposals use 15% on net gains after fees and prior-year loss offsets. These outputs are not a substitute for a full tax return: they ignore other income, deductions, and reporting detail. Real liability depends on your complete records and situation. Consult a tax advisor or accountant for official calculations and filing.
