Complete Guide for Foreigners Filing Taxes in France for the First Time: 2026 DGFiP Explained
🇫🇷
In April, I overheard colleagues discussing "déclaration d'impôts" (tax declaration), and I couldn't help but wonder: I only arrived in France last September, does this concern me? If I have to file taxes in France, what about my income from my home country? Will I be taxed in both places?
This confusion is common, but ignoring it can be costly: as a French tax resident who fails to declare, you face at least a 10% penalty + 0.2% interest per month. Conversely, declaring income that has already been taxed in your home country in France without a tax treaty means paying unnecessarily. This practical guide for 2026 specifically addresses declarations for income earned in 2025.
The key factor is not nationality, but tax residency status. If any of the following conditions apply, you are considered a French tax resident for 2025:
As long as you are a French tax resident → you must declare your global income (France + abroad), not just the salary earned in France.
Common scenarios for 2026:
If you arrive in France mid-year: income earned from the day you officially settle must be declared in France. Income earned before arriving in France is only noted for information purposes in certain cases and remains taxable by your home country.
France has signed bilateral treaties to avoid double taxation with about 130 countries. Among the expatriate communities active on Pionra, the most commonly used treaties in 2026 include:
Practical Steps: Fill out Form 2042 like everyone else, plus Form 2047 ("foreign income"), and include your home country income. The treaty determines the method of taxation: whether it is exclusive to one country or shared between both, with tax credits applied.
For most foreign students in 2026:
A rarely mentioned tip: even if your income is too low to require tax payment, you must still declare. After filing, you will receive a tax notice (avis d'imposition / if no tax is due, it is avis de non-imposition), which is essential for applying for Livret A savings, CAF subsidies, scholarships, Visale guarantees, CSS supplementary health insurance, and for applications to Sciences Po, among other procedures.
Income for 2025 → Declaration from April to June 2026:
First-year filing must be done using paper forms (2042 + 2047, if there is foreign income), as you do not yet have a tax number to file online. Send it to your local SIP (Service des Impôts des Particuliers, Personal Tax Office).
You will receive your tax number + impots.gouv.fr account details 3–5 months after your first declaration, and from the second year onward, everything will be online.
Filing taxes in France may seem daunting, but free assistance is widely available:
Aïcha, a Moroccan student pursuing her master's degree in Toulouse, visited the Maison France Services on rue de Bayard in May 2025. An hour and a half later, her first paper declaration was sent off for free, and she received her tax number in September.
| Situation | Tax Resident? | Need to Declare? |
|---|---|---|
| Student arriving in France in September 2025, foreign scholarship, < 183 days | No | No (but must in 2026) |
| Employee arriving in France in July with family | Yes | Yes (from July onward) |
| 6-month intern (March-August), allowance €700/month | Yes (family in France) | Yes |
| Student + part-time job earning €4,000/year | > 183 days then yes | Yes (mostly should owe €0) |
| Auto-entrepreneur starting in April | Yes | Yes |
| Tourist/visitor < 183 days | No | No |
On Pionra, the Chinese Expat Community, Moroccan Community, and Vietnamese Community share tax filing experiences, reliable bilingual accountants (Chinese-French, Chinese-Vietnamese, Chinese-Moroccan), and practical pitfalls of various treaties. You can find bilingual accountants at /fr/annuaire or post questions in your community (e.g., Algeria, Senegal, Portugal).
Yes. Every French tax resident must declare all foreign bank accounts on Form 3916 / 3916-bis, even if the accounts are dormant. The account balance itself is not taxed, but failing to declare each account incurs a penalty of €1,500 (if the country is listed as a non-cooperative jurisdiction, the penalty is €10,000 — China is not on this list).
No. Gifts from parents to students (children or recently adult children) are not considered taxable income in France as long as the amount is reasonable for daily living. If the total amount exceeds €31,865 (the exemption for manual gifts from parents to adult children within 15 years), it must be declared as a "gift," but it is still not considered "income."
No. According to the French tax code (BOI-RSA-CHAMP-20-30-10-20), CSC scholarships are exempt from income tax — provided they are not remuneration for any paid research work you are doing. However, you need to declare the amount in the "other exempt income" section (1AC format) of Form 2042, as this will enter your "reference tax income," which CAF, CSS, etc., will use.
Not mandatory. However, it is advisable to declare "€0": you will receive a avis de non-imposition (notification of no tax due), which is useful for applying for CAF, CROUS, AME/CSS. File using paper forms in the first year, then switch to online in the second year.
Yes, always. Withholding at the source (PAS) is only based on the previous year's prepayment. The declaration process from April to June each year serves to settle accounts: to report additional income unknown to the employer (interest, rent, foreign income), apply for tax credits (actual expenses, charitable donations, childcare costs), and calculate the actual difference. Not declaring = assuming you want to evade taxes, which will almost certainly lead to back adjustments.
