Binance is the most used crypto exchange in France, but its tax declaration raises specific questions. Between the obligation to declare the account via form 3916-bis and the capital gains calculation using the WAP method, here is everything you need to comply with French tax authorities.
Step 1 — Declare your Binance account via form 3916-bis
Since the 2020 Finance Act, any account opened on a foreign exchange must be declared via form 3916-bis, even without transactions during the year.
Binance is registered in the Cayman Islands and is therefore a foreign exchange. If you have a Binance.com account, you must declare it.
The penalty for omission is €750 per undeclared account.
Step 2 — Export your transaction history
Two methods: API connection (recommended) or CSV export. The API automatically imports your complete history including spot, futures, staking and earn.
For API: Binance → Account → API Management → create a read-only key, then enter it in SafeTax.
For CSV: Binance → Orders → Export. Binance limits exports to 3 months per file and requires separate exports for spot, futures, staking, earn and P2P.
Step 3 — Calculate your capital gains using the WAP method
Once your history is imported, SafeTax applies the French Weighted Average Price (WAP) method to calculate your capital gains.
Crypto-to-crypto exchanges on Binance are not taxable in France and are automatically excluded from the calculation.
Step 4 — Transfer to form 2086
SafeTax calculates your capital gains and tells you line by line what to report in form 2086.
Transfer the totals to your 2042 C declaration (box 3AN) and attach form 2086 as an annex.
