A parent remaining in the country sends several hundred euros each month to a French account. An expatriate repatriates the balance of a foreign account after returning to France. In both cases, the question arises when filling out the income tax return: should these amounts be reported, and if so, on which form? The answer depends less on the amount than on the nature of the transfer, and mistakes in this regard can be costly.
Accounts held abroad: the obligation that many discover too late
One often starts by wondering if the received transfer is taxable. The first question to ask is actually different: do you hold (or have you held during the year) a bank account, a savings account, or a life insurance contract outside of France? If yes, each foreign account must be listed on form n°3916, attached to the annual declaration.

This obligation also applies to accounts opened with neobanks like Wise, Revolut, or N26 when the institution is based outside of France. Since the implementation of the OECD’s CRS standard, automatic exchanges of information between states make these accounts visible to the French tax administration, even without traditional bank documentation. A Wise account based in Belgium or a Revolut account in Lithuania falls within this scope.
To report money coming from abroad to the tax authorities, one fills out form n°3916 (or n°3916-bis for digital asset accounts) online at impots.gouv.fr, specifying the country, account number, institution, and date of opening. The omission, even if unintentional, triggers a regularization procedure and a fine for each undeclared account.

International money transfer and income tax: what is taxed and what is not
The transfer itself is not a taxable event. It is the nature of the transferred amount that determines taxation. A transfer of your own funds from a foreign account to a French account does not create any taxable income: you are moving your money, nothing more.
Amounts that remain non-taxable
- The repatriation of personal savings accumulated before returning to France, provided you can document the origin of the funds (bank statements, employment contract abroad, deposit history).
- Reimbursements of expenses between individuals (sharing wedding expenses abroad, repayment of a family loan documented by a contract, even informal).
- Family gifts below the allowances provided by the general tax code, subject to declaring the gift via form n°2735 within one month.
Taxable amounts to be reported on form n°2047
Income received abroad (salaries, rents, dividends, pensions) must be included on declaration n°2047, and then reported on the main declaration n°2042. Even income already taxed in the source country must be reported, as France applies either a tax credit or an exemption with progression, depending on the applicable tax treaty with the concerned country.
Responses vary on this point: some taxpayers believe that a foreign salary already taxed locally does not need to be mentioned in France. However, the administration considers that the French tax resident must declare all of their worldwide income, and then applies the conventional mechanism to avoid double taxation.
Cash transfers and customs declaration: the threshold to know
Money transfer does not always go through a bank transfer. When physically transporting cash, checks, or securities across a border, any amount equal to or greater than 10,000 euros must be declared to customs. This obligation also applies to intra-European Union transfers, not just to entries from a third country.
The declaration is made via the CERFA form n°13426 before passing through customs (or online at demarches-douanieres.gouv.fr for intra-EU transfers). The absence of a declaration exposes one to a fine that can reach a quarter of the undeclared amount, in addition to the immediate seizure of the funds.
Tax audits and transfers via fintechs: what has changed recently
The anti-fraud plans implemented since 2023 have tightened the regulatory framework. The cross-referencing of international banking data (automatically transmitted via the CRS system) and declarations n°2042/2047 is now systematic. TRACFIN and the DVNI (Directorate of National and International Verifications) include flows passing through fintechs in their monitoring scope.
In practice, a regular transfer received via Wise or Revolut appears in the same databases as a classic SWIFT transfer. The idea that a transfer between individuals via a neobank escapes detection is outdated.
Documents to keep for a possible audit
The administration adopts a differentiated approach depending on the size and recurrence of the flows. For modest and regular transfers to a relative (family assistance), a solid file is often enough to close the audit without adjustment. In contrast, significant flows without an identifiable economic cause trigger a request for formal justification.
- Employment contracts or pay slips abroad, to document the origin of repatriated savings.
- Family burden certificates, email exchanges, or proof of family ties, for regular assistance transfers.
- Notarial deeds or loan contracts (even private ones), for reimbursements between individuals.
- Bank statements from the foreign account showing the history of movements.
The quality of these documents directly impacts the classification retained by the auditor: a documented transfer remains a movement of funds, an unexplained transfer becomes presumed income.
The most common trap is not the taxation itself, but the omission of form n°3916 for a foreign account or form n°2047 for income already taxed elsewhere. These omissions, often made in good faith, generate fines and penalties that could have been avoided in a few minutes on impots.gouv.fr. It is better to declare a transfer that turns out to be non-taxable than to report nothing and have to explain it three years later.
