Is Filing Your Income Tax Return the First Step After Moving to France?

You have just settled into your new life in France. The café culture, healthcare, and quality of life are everything you hoped for. Now you are ready to address your French tax obligations. How complicated could it be?

You receive retirement income from an IRA, maybe some Social Security benefits, plus dividends and interest from your investments. You also heard you need to report your foreign bank accounts. A quick tax return should sort everything out, right? Incorrect. And this misconception could cost you dearly.

The Hidden Complexity That Catches Most New Residents Unprepared

What seems straightforward is actually a complex system of French tax obligations that extends far beyond a simple income tax return. Many foreigners discover this only after receiving penalty notices or during a tax audit.

The truth is, filing your French income tax return is not the first step. Before you can file anything, you need to:

  • Obtain your French tax identification number (numéro fiscal)
  • Activate your personal space on the French tax authorities’ website (impots.gouv.fr).

The goal is to be able to file your first income tax return online, since paper returns come with significantly shorter deadlines. Miss these preliminary steps, and you are already behind schedule.

You May Be Required to File Returns You Have Never Heard Of

At this stage, the situation becomes more complex. Depending on your circumstances, your French tax obligations may include filing several specialized returns that most newcomers are unaware of:

  • Wealth Tax Return (IFI) – If your French (or worldwide, depending on your situation) real estate exceeds €1.3 million
  • Tax return for the differential contribution on high income.
  • Real estate capital gains tax returns.
  • Property Owners’ Declaration – required for all property owners in France.
  • Annual 3% Tax on Real Estate – for properties owned through entities.
  • Trust Tax Returns – both annual and event-based filings required.
  • Gift and Inheritance Tax Returns – often overlooked by foreigners living in France.

Each of these tax returns has its own filing deadline, rules, and penalty structure.

The Price of Noncompliance

The French tax authorities do not take missing returns lightly. The consequences are severe, including:

  • Late interest: 0.2% per month on taxes owed.
  • Surcharges: 10% to 80% of the tax due.
  • Fines: for example, a €20,000 penalty per missing annual or event-based trust tax return.

A single overlooked trust return could result in a €20,000 fine, and you may be liable for additional penalties.

The 10-Year Audit Window You Need to Know About

Perhaps most alarming: if you own foreign accounts and fail to report them, the French tax authorities have 10 years to audit your household. That is a decade during which a simple oversight could resurface as a significant financial liability.

The Smart First Step: A Comprehensive Tax Assessment

Rushing to file a tax return without understanding your complete French tax profile can be a costly mistake. We have seen well-meaning clients try to save on advisory fees, only to face significant penalties for missed filings.

Our recommended first step? A thorough review of your financial situation to determine:

  • How will your specific income sources be treated under French tax law?
  • Which reporting requirements apply to your household?
  • What does your filing calendar look like for the entire year?
  • What other legal and tax implications are triggered by your move to France?

This assessment is not an unnecessary expense. It helps prevent future penalties.

Already Living in France? It Is Not Too Late

If you have been in France for several years and suspect you may have missed reporting requirements, act now.

The longer you wait, the more penalties you will face in case of a tax audit. And remember, that 10-year audit window is ticking. The good news is that voluntary disclosure is always preferable to waiting for the tax authorities to identify the issue themselves.

With the help of a tax attorney, you can voluntarily rectify your tax situation with the French tax authorities and often benefit from reduced penalties. More importantly, bringing your filings into compliance will give you peace of mind.

Do not let your experience in France become a tax burden. Understanding your complete French tax obligations before filing is not just smart; it is essential.
