Official source: French tax authority guidance on digital-asset gains.

If you live in France — as a citizen or an expat — your crypto activity falls under French tax rules, whatever the platform's country. The French regime is actually one of the more readable ones in Europe, once you know its two or three core principles. Here is the plain-English overview for 2026.

Important: this is general information, not tax advice. Rules evolve and individual situations differ — check the official documentation or consult a professional for your case.

The core principle: tax at the fiat exit

For private individuals, capital gains on digital assets fall in principle under the flat-rate levy of around 30% (income tax plus social contributions). The key subtlety is what triggers a taxable event:

• Holding crypto: not taxable.
• Selling for euros (or any fiat): taxable event.
• Swapping crypto for crypto (BTC → USDT included): not a taxable event for private individuals — the tax is deferred until you exit to fiat.
• Paying for goods or services in crypto: treated like a fiat exit — taxable.

This deferral on crypto-to-crypto swaps is the distinctive feature of the French regime, and it changes how active users manage their positions.

The gain is computed on your whole portfolio

France does not compute gains sale by sale. Each fiat exit realizes a fraction of the overall gain of your entire portfolio, based on total acquisition cost versus total portfolio value at the time of sale. In practice you need two numbers at every taxable sale: what your whole portfolio is worth, and what it cost in total. Keep records.

Foreign platform accounts must be declared

Accounts opened on platforms established abroad — which includes most major exchanges — must be declared each year alongside your income return, one form per account, even if the account is dormant. Forgetting this declaration carries fixed fines per account per year; it is the cheapest mistake to avoid in the entire system.

Occasional versus professional activity

The ~30% regime targets occasional private investors. Trading with professional-like intensity, tooling and leverage can be reclassified into a professional regime with different (usually heavier) rules. High-frequency traders should get personal advice.

Earn, staking and other income

Rewards from staking or savings products add a layer of complexity (income at receipt and/or gain at disposal, depending on analysis). At minimum, log every reward: date, amount, market value in euros — whatever regime ends up applying, that record is what you'll need. See our OKX Earn guide for how these products work.

The classic mistakes

1. Not declaring foreign accounts — automatic fines, easily avoided.
2. No transaction history — export your trades regularly; reconstructing years later is painful.
3. Believing crypto-to-crypto swaps are taxable (over-declaring) or that fiat exits under some imaginary threshold are exempt (under-declaring). There is a genuine small-disposals tolerance only when total annual disposals stay very low — check the current threshold before relying on it.
4. Forgetting that P2P sales are fiat exits too — cashing out via P2P is a disposal like any other.

FAQ

Does the platform report or withhold tax for me? No — declaration is your responsibility. The platform provides history exports; the return is yours to file.

I only swapped BTC for USDT this year — do I owe tax? In principle no, crypto-to-crypto is deferred. You still must declare the foreign account itself.

Do these rules apply if I use OKX? Yes — residence determines taxation, not the platform. OKX operates in the EU under MiCA authorization (details in our review), but French tax rules follow you on any platform.
