If you are a first-time expat in France (or returning) in 2026, understanding which declarations and forms apply to your situation is essential for remaining compliant with French tax laws. One notable change for this year is that starting 1 January 2026, declaring gifts between private individuals is online-only. This update may be a significant shift for those accustomed to paper-based filing habits from previous years. For a full overview of the filing process, see our complete guide to filing French taxes as a UK expat.
Key Takeaways
| Question | Short Answer |
|---|---|
| Do first-time expats in France need to file a French tax return in 2026? | Yes, if you became a French tax resident in 2025 or have French-source income, you must file a 2026 return covering your 2025 income. |
| Which form do most first-time expats and returning residents use? | Form 2042 is the standard income return; Form 2042-NR applies to non-residents with French-source income up to their return date. |
| Must you declare foreign bank accounts as an expat in France? | Yes. Every foreign bank account held or used in 2025 must be declared using Form 3916, filed alongside your income return. |
| What is the 2026 paper filing deadline for income tax? | Tuesday 19 May 2026 at midnight, even for French residents living abroad. |
| Does a returning expat pay IFI (wealth tax) on worldwide real estate? | If you were fiscally domiciled outside France for the prior 5 calendar years, you are only taxed on French-situated assets for your first five years. |
Why 2026 Is Different for First-Time Expats in France
The French tax administration (DGFiP) has updated several processes for the 2026 filing season, which covers your 2025 income. If you arrived in France during 2025, or returned after years abroad, this is your first 2026 return, and the rules are specific to your arrival status.
A major practical shift is that online declaration is increasingly mandatory. While paper options still exist for certain situations, digital is now the default expectation. Specifically, some transactions, such as gift declarations, have moved entirely online as of 1 January 2026.
Are You a Tax Resident?
Before selecting forms, you must determine if France considers you a tax resident. According to impots.gouv.fr, you are generally a French tax resident if any one of the following applies:
- Your primary home (foyer) is in France.
- Your main professional activity is carried out in France.
- France is the centre of your economic interests (where your main investments or assets are managed).
If you meet these criteria, you are typically taxed on your worldwide income. Non-residents with French-source income file under a different status with specific forms.
Which Forms Apply to First-Time Expats and Returning Residents
Using the correct forms ensures accuracy and prevents administrative delays. Here is a breakdown of the primary forms for 2026:
| Form | Who Uses It | What It Covers |
|---|---|---|
| 2042 | French tax residents | Worldwide income: salary, rental, investment, etc. |
| 2042-NR | Non-residents or mid-year returnees | French-source income from 1 January to your return date. |
| 3916 | Anyone with foreign bank accounts | Declaration of accounts opened, held, or closed during 2025. |
| 2047 | Residents with foreign-source income | Foreign income details that feed into Form 2042. |
| 2042-IFI | Those subject to real-estate wealth tax | Net taxable real-estate assets exceeding €1.3 million. |
| Online Equivalent of 2735 | Anyone declaring a gift (don manuel) | Gifts between private individuals (online-only as of 2026). |
Pro tip: If you arrive in France for the first time from the UK mid-year, you only need to file Form 2042 (plus Form 2047 for any relevant foreign income) for the period after you arrived. Form 2042-NR is used for non-residents with French-source income, or residents who returned mid-year who need to declare French-source taxable income from 1 January up to the date of their return to France.
Declaring Foreign Bank Accounts (Form 3916)
This is a frequently missed obligation. If you held, opened, or closed any bank account outside of France during 2025, you must declare it. This includes current and savings accounts, brokerage accounts, and digital wallets with banking features. Failure to declare can result in significant penalties per account.
Wealth Tax (IFI) and Returning Residents
The real-estate wealth tax (IFI) applies if your net taxable real-estate assets exceed €1.3 million. However, returning expats may benefit from a specific provision: if you were fiscally domiciled outside France for the five years prior to your return, you are only taxed on French-situated assets for your first five years back in the country.
Critical 2026 Filing Deadlines
| Deadline Type | Date | Who It Applies To |
|---|---|---|
| Paper Returns | Tuesday 19 May 2026 | All paper filers, including residents living abroad. |
| Online Returns | Late May / Early June 2026 | Varies by département number. |
| Gift Declarations | Within one month of gift | Mandatory online filing for all private gifts. |
All rates, thresholds, and filing dates are confirmed via impots.gouv.fr. Foreign income must be converted to euros using official exchange rates — Taxpert's filing assistant handles this automatically, applying Banque de France rates to each transaction so your totals are filing-ready.
Getting Your First French Return Right
Filing for the first time in France is one of those tasks that feels more daunting than it is — once you understand which forms apply to your situation. The key steps are: confirm your residency status, gather your foreign income records, declare all foreign accounts on Form 3916, and file online before your zone deadline. If you're a UK expat with UK-source income to declare, the full filing guide covers every step in detail.
Frequently Asked Questions
Do I have to declare my UK or US bank account in 2026?
Yes. Any foreign bank account held during 2025 must be declared on Form 3916 alongside your income return. This applies even if the account was inactive or only held a small balance.
How do I convert foreign income to Euros for my return?
The DGFiP expects you to use the official exchange rate applicable on the date the income was received. This is typically based on the Banque de France or ECB daily rates rather than a year-end average.
What happens if I miss the filing deadline?
Late filing can result in a 10% surcharge on your tax bill, which can increase if the return is not filed after a formal notice. It is always advisable to file on time or contact the tax office early if you anticipate difficulties.
