Moving from France to Monaco: why nationality decides the result
This is the corridor where Monaco's famous 0% personal income tax answer breaks: French nationals remain taxable by France under the 1963 Franco-Monégasque Convention, regardless of moving their home to Monaco.
The rule is nationality-based
Monaco applies 0% personal income tax across income types to non-French nationals. The 1963 Convention is different: it keeps French nationals in the French tax net. Changing residence does not change that nationality-based result.
That makes this pair fundamentally different from UK-to-Monaco. The first eligibility question is nationality, before property, presence or portfolio composition.
France remains a high-tax source market
France's 2026 PFU is 31.4%, with social charges of 18.6%, and the top income-tax band is 45% from EUR 181,917 before social levies. IFI reaches net real estate above EUR 1.3M, while financial assets are exempt.
French residence itself can arise through any one of four Article 4B tests. The 183-day figure is only indicative; home and family ties can decide the case on far fewer days.
Monaco does not provide an investment route
Monaco has no investment-residency route. Residency is based on accommodation and a clean criminal record, and no codified day-count threshold was verified. French nationals should not incur the cost of a move before testing the Convention.
Before you move
- The 1963 Convention keeps French nationals taxable by France; Monaco residence does not override it.
- France's PFU is 31.4% in 2026, not the old 30% figure.
- A French home or family can create residence without relying on a 183-day count.
