Moving to France: tax residence is about more than counting days

“I spend fewer than 183 days in France, so I cannot be French tax resident.”

This is a common assumption among people dividing their time between countries. It can also lead to unexpected tax liabilities. The number of days spent in France matters, but it is only part of the analysis.

Start with your personal and professional circumstances

Under French domestic rules, tax residence may arise from your home or principal place of stay, your professional activity in France, or the centre of your economic interests.

These are alternative tests. Spending fewer than 183 days in France does not necessarily prevent French tax residence if another criterion is met.

For example, regularly travelling abroad for work does not, by itself, establish that your tax residence is outside France when your family home remains here.

What if two countries consider you resident?

An international move can result in both countries treating you as tax resident under their own rules.

Where an applicable tax treaty exists, its residence provisions must then be examined (France has signed more than 100 of those). Depending on the treaty, the analysis may consider your permanent home, personal and economic ties, habitual abode and nationality.

A foreign tax return or a residence permit does not, on its own, settle the French tax analysis.

Why the answer matters

French tax residents are generally subject to French income tax on worldwide income, subject to applicable treaty provisions. Keeping income in a foreign bank account does not automatically place it outside the French tax system.

Tax treaties may provide relief from double taxation. However, paying tax abroad does not necessarily remove the obligation to report the income in France.

Prepare before your first French tax return

Your moving date, family arrangements, working pattern and sources of income should be reviewed together. Identifying these issues early helps establish a consistent position and prepare the supporting documents.
