The France-Monaco tax treaty: who taxes what, and how to use it
Special treaty: French nationals living in Monaco generally remain taxable in France as if resident (art. 7).
The 60-second essentials
- Your securities gains can be purged almost tax-free before any move to France: on €110,000 of latent gains, about €34,540 is at stake (2026 French flat tax: 31.4%).
- Your French rents and property gains stay taxed in France throughout non-residence: 17.2% social levies (unfurnished) or 18.6% (furnished); the average-rate option is worth computing every year.
- This treaty also covers inheritance: a rare privilege (about thirty conventions in the whole French network).
- France’s inbound regime (art. 155 B) can exempt part of your pay for up to 8 years, provided the contract is signed BEFORE you move.
- Treaty-specific caution: Special treaty: French nationals living in Monaco generally remain taxable in France as if resident (art. 7).
Tax residence: the Monaco-France match
Everything starts here: no treaty benefit exists for someone who remains French tax-resident. France’s art. 4 B casts three independent nets (home, main activity, centre of economic interests) and one is enough. If both States claim you, the treaty cascade decides: permanent home, centre of vital interests, habitual abode, nationality, in that strict order. The evidence file is built during the expatriation, never after.
Who taxes what, income by income
Near-universal standard: income from immovable property is taxable where the property sits. Your French rents and property gains remain taxed in France whatever your residence.
As a non-resident you file in France every year. Tax is computed at the 20% minimum rate (30% above a threshold) unless the average-rate option is better, which it often is. Social levies: 17.2% (unfurnished) / 18.6% (furnished).
On €19,200 of yearly unfurnished rent, the default take (20% + 17.2%) reaches €7,142: compute the average-rate option every year.
OECD-model principle: salaries are taxable where the work is physically performed, with a framed exception for short assignments (the 183-day rule, exact conditions in the text).
Working in Monaco, your local pay is taxed nowhere as long as you are genuinely non-resident of France and the work is performed locally: that is the treaty’s appeal, and its fragility if residence is contestable. Days worked in France can become taxable in France.
Shared taxation: the residence State taxes, and the source State may withhold up to a treaty cap. The exact cap is read in the official text linked above.
On the French side, the domestic withHolding on dividends paid to a non-resident individual is 12.8%, adjusted to the treaty cap where lower. Forms 5000/5001 secure the treaty rate at source; without them you pay the domestic rate and wait months for refunds.
We never publish an unverified treaty rate: the exact cap for this treaty is pinned on the official text during missions.
Same sharing logic as dividends, with an eventual source withHolding capped by the text.
A favourable French quirk: France generally does not withhold on interest paid to non-residents (except non-cooperative jurisdictions, 75%). Treatment therefore mostly depends on local law and on your French filing after the move.
Classic architecture: private pensions are generally taxable in the State of residence; government pensions in the paying State; social security pensions follow the text’s own rule.
Retired in Monaco: each pension’s nature (private, government, social security) decides which State taxes it. A misqualified pension means double taxation or reassessment.
General treaty rule: gains on securities are taxable in the seller’s State of residence. Classic exceptions to pin on the text: substantial participations and real-estate-rich companies.
Local law does not tax private gains: the non-residence window allows a near-total purge. Sell (even rebuy immediately) before the move: a new cost basis is set and only post-move gains will ever face French tax. Execute before the residence transfer, never after.
On €110,000 of latent gains purged before the move: about €34,540 of French flat tax neutralised.
On the French side, non-residents face IFI only on French real estate, above €1.3M of net taxable property wealth (French rule, 2026).
Few treaties cover wealth tax: absent an express clause to pin on the text, the French rule above stands. After a move to France, foreign property enters the IFI base, with a partial 5-year relief for new arrivals.
Income-tax treaties and inheritance treaties are separate texts: coverage of one never implies the other.
A rare privilege: this treaty has treaty inheritance coverage. Used upstream (structuring, lifetime gifts), it can keep non-French assets out of French inheritance duties despite France-resident heirs. One of the strongest planning levers in the network.
The local tax system, in brief
No personal income tax: no tax on salaries, private capital gains or dividends, and no inheritance duties comparable to France’s. Practical consequence: almost the entire tax question lives on the French side, and every French rule (residence, source, the move itself) counts double.
Known convention specifics
- The Monaco zero-income-tax regime does not benefit French nationals (art. 7)
- For a foreign national, Monaco remains a zero-income-tax convention with a 1950 inheritance treaty
Three worked examples (2026 French rules)
Case 1, the purge. €110,000 of latent gains. Sold (and rebought) before the move: taxed nowhere, new cost basis set. Sold six months after the move: €34,540 of French flat tax. Same trade; the date is worth €34,540.
Case 2, French rent. €19,200 of unfurnished French rent: the default take is €7,142 (20% minimum + 17.2%); the average-rate option, recomputed yearly, often cuts it sharply.
Case 3, moving to France with art. 155 B. Hired into France at €100,000 gross with the contract signed before the move: a 30% impatriation premium (€30,000) is income-tax exempt, worth about €9,000 per year at a 30% marginal rate, renewable up to 8 years. The same contract signed one week after the move: zero.

The treaty’s classic traps
1. Purging too late. Selling ’on arrival’ instead of before leaving Monaco: historical gains become French-taxable at 31.4%. The window closes on the day residence transfers.
2. Signing the contract after the move. France’s inbound regime (art. 155 B) requires recruitment from abroad: a contract signed once back closes up to 8 years of exemptions. No cure.
3. Never computing the average rate. The 20/30% minimum applies by default; for many profiles the average rate is lower. Not running the numbers each year is paying an optional tax.
4. Ignoring the inheritance coverage. This treaty has rare treaty inheritance coverage: not using it in your estate structuring wastes a major lever.
FAQ
Is the 1963 treaty still in force in 2026? Yes, subject to the caution flagged above. Recent changes come mostly from French domestic law (31.4% flat tax and higher social levies in 2026, IFI unchanged at €1.3M): what moves is the treaty/domestic-law interface.
How do I prove tax residence in Monaco? Through real life, not paperwork alone: a permanent home, actual presence, schooling, accounts and activity on the spot, plus the local tax-residence certificate. The evidence file is built during the expatriation; it is nearly impossible to reconstruct afterwards.
Do I still file in France while abroad? Yes, as long as any French-source income remains: rents, dividends, property gains. The non-resident return stays annual, at the 20/30% minimum unless you opt for the average rate.
Will my heirs in France be taxed on my foreign assets? This treaty’s inheritance treaty allocates taxing rights between the two States: structured upstream, it can shield non-French assets.
