TL;DR
You face a fine of 10,000 euros per undeclared bank account when the account is held in a state or territory that has not concluded an administrative assistance agreement with France allowing access to banking information to combat tax fraud and evasion.
The condition for application
The increase concerns the non-declaration of a bank account subject to the reporting obligation provided for by Article 1649 A of the CGI.
The account must be held in a state or territory that has not concluded an administrative assistance agreement with France to combat tax fraud and evasion allowing access to banking information.
The amount of the fine
The ordinary fine is 1,500 euros per undeclared account.
It is increased to 10,000 euros per account when the condition relating to the state or territory concerned is met.
The amount is therefore assessed account by account, and not as an overall maximum applicable to all accounts.
The years concerned
The fine applies for each year that is not time-barred for which a declaration should have been filed.
The penalty may therefore be calculated by taking into account both the number of undeclared accounts and the years concerned.
