Moving to the United States is a tremendous opportunity, but it also means a radical change in terms of taxation. Unlike in France, where the government calculates taxes based on declared income, in the United States taxpayers are responsible for calculating their own taxes in addition to declaring all of their income and assets worldwide.
This includes not only their US and worldwide income, but also bank accounts, investments, and life insurance policies held abroad. This obligation of transparency is often misunderstood by French expatriates, who sometimes discover the severity of the US tax system too late.
1. Self-assessment: a fundamentally different system
The US tax system is based on the principle of self-assessment:
- Each taxpayer must complete their annual tax return (Form 1040).
- Global income is taxable in the US, even if it has already been taxed in France.
- Foreign bank accounts must be reported via the FBAR (Foreign Bank Account Report) if the total maximum balances exceed $10,000 at any time during the year.
- Financial investments and certain structures (life insurance, civil companies, family holding companies, etc.) must be reported on Form 8938 (FATCA) if their value exceeds certain thresholds ($50,000 for a single person, $100,000 for a couple).
Example: a French expatriate who has a Livret A savings account in France with €15,000 must declare it via the FBAR and possibly via FATCA. Failure to do so, even through ignorance, may result in penalties.
2. Penalties for failure to comply
The United States has a policy of virtually zero tolerance for failure to comply, even if unintentional. The penalties are among the most severe in the world:
- Failure to file an FBAR: a fine of $10,000 per account per year, even if there was no fraudulent intent.
- Intentional or repeated omission: fine of up to 50% of the undeclared amount per year.
- Failure to file FATCA: minimum fine of $10,000, which may be increased to $50,000.
- In serious cases, criminal penalties may be imposed.
Example: A French entrepreneur living in Miami fails to report a €100,000 account in France. The IRS may impose a fine of $50,000 in the first year of omission, i.e., half of the amount.
3. The importance of professional support
- Navigating between two tax systems—French and American—is complex. Many expatriates think they can manage their tax returns on their own, but this represents a considerable risk. A specialized professional can:
- Ensure that all required forms (1040, FBAR, 8938, 3520 for certain trusts, etc.) are completed correctly.
- Identify applicable tax credits and tax treaties to avoid double taxation.
- Optimize the management of cross-border assets (real estate, life insurance, bank accounts).
- Anticipate the tax implications of returning to France or transferring assets.
Example: A French family living in New York can avoid more than $70,000 in penalties by entrusting their tax compliance to a CPA specializing in French-American taxation. Thanks to the tax treaty, double taxation can be avoided at the federal level.
4. How can you rectify an error?
Discovering that you have failed to declare a foreign account or income is not a disaster, provided you act quickly and in good faith. The United States offers voluntary disclosure programs that allow you to correct your situation while limiting penalties.
- Streamlined Filing Compliance Procedures: allows you to regularize several years of missing returns with reduced penalties (5% of undeclared assets).
- Voluntary Disclosure Program: reserved for more serious cases, with heavier penalties but a reduced risk of criminal prosecution.
Example: an expatriate in San Francisco who has not filed three years of FBARs can regularize their situation by paying a reduced penalty of 5%, instead of $150,000 if they had waited for a notification from the IRS.
5. Beyond compliance: wealth management issues
Tax transparency is not just a constraint; it can also be integrated into a broader wealth management strategy:
Optimize the structure of your asset holdings (France/United States).
Secure family succession by adapting wills and matrimonial regimes to US law.
Use US retirement and insurance products (401(k), life insurance) to benefit from tax advantages while complying with the law.
Example: a French-American couple in Los Angeles can reorganize their assets between France and the United States. The result: better tax coverage and easier transfer to their children, with less risk of double taxation.
Conclusion
Tax transparency is an essential requirement for French expatriates in the United States. Self-declaration, severe penalties, and complex international rules make it necessary to stay informed and seek expert advice.
