Who Has to Declare Income in France?
You have to report your income to the tax department if you are resident in France or if your tax domicile is in France.
⚠️ Warning
If you reside abroad but receive income from France, you must also declare your income in France.
You must file a tax return even if you received little or no income. Doing so can allow you to:
Obtain a notice of non-taxation, which may be required for certain aids (e.g., housing aid)
Request a refund of tax credits you’re entitled to
Example:
You can get a refund for childcare expenses, whether the care is provided at your home or elsewhere.
You must file a single declaration for the entire tax household. This means the income and expenses of all members in the household are taken into account to calculate a single tax obligation.
