Built for DGFiP crypto tax filing

Every nuance of the French regime, applied so your declaration is consistent year over year.

PFU 30% flat tax

12.8% income + 17.2% social contributions, applied to your annual net gain. Progressive option computed in parallel so you can pick the lower of the two.

Crypto-to-crypto exempt

Swaps stay outside the tax base under French rules. We track them for cost-basis purposes without counting them as taxable events.

Form 2086 line by line

Each cession populated with acquisition value, sale value, fraction of total portfolio. The exact format DGFiP expects.

Form 3916-bis foreign accounts

Every non-French exchange account you hold, listed with the right Annexe details. Failing to declare attracts a €750 penalty per account.
