Wealth management in Monaco

"Alexis, I'm moving to Monaco next year. Everyone tells me there's no tax. So why is my accountant asking what year I was born and how long I've been living there?"

Because those two questions decide everything. Monaco is the destination where a French national's tax position depends least on their assets and most on their nationality and the date they settled there.

The Principality is home to 5,656 French nationals on the consular register at 31 December 2025, a change of −7.02% year on year — the sharpest fall in our panel. The French nevertheless remain one of the two largest communities there.

Two separate treaties apply, and they do not overlap. The treaty of 18 May 1963 covers income tax; the treaty of 1 April 1950 covers inheritance. At Balmont Conseil, we read both, because confusing one with the other is the most common mistake on this kind of file.

1. Why seek expert wealth management in Monaco?

Four points, and none of them concerns the make-up of your assets.

• Article 7 of the 1963 treaty. French nationals who moved their domicile or residence to Monaco on or after 13 October 1957, or who cannot show five years of habitual residence there at 13 October 1962, remain liable to French income tax on the same terms as if they lived in France.
• The five-year rule in the 1950 estate tax treaty. A French national can only be treated as domiciled in Monaco at death if they had actually been habitually resident there for at least five years at that date.
• The spouse's nationality. Article 7 applies to French nationals. A spouse who is not French falls outside its scope, which can create two separate regimes within the same household.
• What the 1950 treaty does not cover. It applies to inheritance taxes. It expressly excludes taxes on lifetime gifts.

2. The France ↔ Monaco framework in five verified points

Here is the applicable framework, checked against the text of both treaties and official sources as at 15 September 2026.

The five-year rule, straight from the text. Article 1^st (c) of the 1950 treaty provides that "persons of French nationality may only be regarded as having been domiciled in the Principality at the time of their death if, at that date, they had in fact been habitually resident there for at least 5 years". The exceptions are members of the Sovereign Household and officials and employees of the Monegasque public services, for whom no minimum period is required.

Practical consequence. A French national who dies less than five years after settling there is not treated as domiciled in Monaco for the purposes of this treaty. The timing of the move then stops being a formality and becomes a factor in the transfer of the estate.

On exit tax, a useful clarification. An administrative list from 2012, still widely copied, placed Monaco outside the automatic deferral of payment. The list in force, as drawn up at 8 October 2025, shows the opposite for income tax. We check this point on every file — bearing in mind that a French national covered by Article 7 of the 1963 treaty first raises the question of whether they are really moving their tax domicile at all.

3. Our services: 360° support for expatriates and investors

Three workstreams, in the order in which they determine the others.

Determining your position under Article 7

This is the absolute prerequisite. We establish, with supporting documents, whether or not you fall within the scope of Article 7 of the 1963 treaty: nationality, date on which your domicile or residence was moved, position at 13 October 1962 where relevant, and special cases recognised by case law.

The outcome determines how your income is taxed — and, in practice, your entire wealth strategy. Two French neighbours in Monaco can fall under opposite regimes.

• A written, sourced position on how Article 7 applies.
• The separate position of each household member according to their nationality.
• Consequences for income tax and IFI (real estate wealth tax).

Estate timeline and the five-year rule

We pin down the exact starting date of your habitual residence in Monaco and work out the date on which the five-year rule of the 1950 treaty will be met.

In the meantime, we adapt the structure of your assets to this interim period. It is as much a matter of timing as of structuring, and it is rarely done.

Gifts, estate transfer and investment wrappers

The 1950 treaty does not cover lifetime gifts: they are therefore governed by each State's domestic law, notably Article 750 ter of the French Tax Code. Paragraph 3 of that article makes taxable in France all assets received by a donee who has been domiciled in France for at least six of the last ten years.

On investment wrappers, we look at what to keep and what to reallocate. A Luxembourg assurance-vie contract offers a framework that does not depend on the policyholder's residence, which is particularly useful while Monegasque status is not yet established.

4. Methodology: our way of working

We work in four stages, and at each stage you know where you stand.

1. The initial review. We establish your actual situation: the make-up of your wealth, the project timeline, the situation of each member of the household, and the tax domicile of your heirs — because it is theirs that counts, not yours.
2. The applicable framework. We set out, source by source and with its date, the framework that applies to you. What we do not know, we mark “to be confirmed” — never anything else.
3. The choices. We present the options with figures and their respective consequences, and you decide. Wealth structuring comes after the decision, not before.
4. Ongoing monitoring. An annual review, free of charge, to check that the framework has not moved — treaties are amended, incentive regimes are abolished, thresholds change.

5. What the firm offers you

What concretely sets our work apart.

• Sources, not claims. Every item in your file carries its reference and its date. You can check. It is the only way to work on a subject where most of the information available online is out of date.
• A single point of contact in France. We coordinate your local advisers; we do not replace them: the host country's domestic tax rules are handled with a qualified professional on the ground. Our role is to keep the whole picture consistent and to defend the French side of the file.
• Fees that are easy to understand. Fees disclosed before any commitment: fixed-price reviews, tailor-made engagements at €500 incl. VAT per hour, insurers' commissions on contracts taken out. The annual review is free of charge.

Frequently asked questions: Monaco

Does a French citizen living in Monaco pay French income tax?

Often, yes. Article 7 of the treaty of 18 May 1963 provides that French nationals who moved their domicile or residence to Monaco on or after 13 October 1957, or who cannot show five years of habitual residence there at 13 October 1962, remain liable to French income tax on the same terms as if they lived in France.

So the absence of income tax in Monaco is real for residents in general, but this category of French nationals does not benefit from it. It is the first point to establish.

Where does the five-year inheritance rule I keep hearing about come from?

From Article 1^st (c) of the estate tax treaty of 1 April 1950 — a separate text from the 1963 treaty, which explains the frequent confusion.

It provides that French nationals can only be regarded as domiciled in Monaco at the time of their death if they had in fact been habitually resident there for at least five years at that date. Members of the Sovereign Household and employees of the Monegasque public services are exempt from this length-of-residence condition.

Are gifts covered by the 1950 convention?

No. Its Article 1^st (b) expressly states that taxes on lifetime gifts are not covered.

Gifts are therefore governed by each State's domestic law, notably, for France, Article 750 ter of the French Tax Code. This is a decisive point when you are considering passing on assets during your lifetime from Monaco.

My spouse is not French. Does that change their regime?

Article 7 of the 1963 treaty applies to French nationals. A spouse who does not hold French nationality falls outside its scope.

This can result in two separate regimes within the same household, with consequences for income tax returns, IFI (real estate wealth tax) and estate transfer. We establish each person's position separately.

Will I pay CSG on my French-source income?

On your French-source property income and property capital gains, the rate is 17.2%. The exemption from CSG and CRDS is reserved for people covered by a compulsory scheme in a European Economic Area State, Switzerland or the United Kingdom, and Monaco belongs to none of these.

If you also fall under Article 7 of the 1963 treaty, your situation needs a specific review, since liability to social charges depends on actual social security cover, not only on your income tax status.

In summary

Monaco is not the tax-free destination it is made out to be: it is a destination where a French national's regime depends on their nationality and the date they settled there, under two separate treaties, of 1963 and 1950.

The whole job is to establish your exact position under these two texts and to draw a timeline from it. It is less spectacular than a tax structure, and far more useful.

Firm's fees: €500 incl. VAT per hour. Annual follow-up is free of charge.

Let's review your situation

A thirty-minute conversation is enough to establish whether you fall under Article 7 and where you stand on the five-year rule. You can also start with a free contract X-ray.
