Comparing taxation between countries involves measuring several parameters simultaneously: income tax rates, corporate taxation, inheritance tax, and the existence or absence of a wealth tax. A low nominal rate is not enough to guarantee a truly reduced tax burden, especially when French reporting obligations or European blacklists neutralize the expected advantage.
Flat tax, special regimes, and corporate tax: comparative table
The differences in taxation between popular destinations for French expatriates are better understood in a table than in a list of promises. Here are the key parameters for several frequently cited jurisdictions.
| Country | Income Tax (max. rate) | Corporate Tax | Inheritance Tax | IFI or equivalent |
|---|---|---|---|---|
| United Arab Emirates | 0 % | 9 % (since June 2023) | None | No |
| Monaco | 0 % | Variable depending on activity | None (direct line) | No |
| Andorra | 10 % | 10 % | None | No |
| Bulgaria | 10 % | 10 % | Low | No |
| Italy (impatriate regime) | Flat tax on foreign income | 24 % | 4 % (direct line, after deduction) | No |
| France | 45 % | 25 % | Up to 45 % | Yes |
This table shows that the absence of income tax does not mean the total absence of taxation. The UAE, long presented as a zero-tax territory, now applies a 9 % levy on corporate profits. A freelancer or a manager billing through a local structure must take this parameter into account.
The choice among countries with favorable taxation therefore depends on the type of income received and the overall wealth, not just the rate displayed on individual income.
EU blacklist: the parameter that rankings ignore
The European Union updated its list of non-cooperative tax jurisdictions on October 8, 2024. Among the countries added or maintained are Panama, Russia, the U.S. Virgin Islands, and Anguilla.
For a French taxpayer, being on this list has direct consequences:
- Increased withholding taxes on financial flows to these jurisdictions, which reduces the expected net tax gain.
- Strengthened anti-abuse measures: the French tax administration can reclassify a structure involving a listed jurisdiction, even if the taxpayer actually resides there.
- Increased reporting obligations: bank accounts, offshore structures, trusts must be declared with a higher level of detail, under penalty of heavy sanctions.
A country that shows a tax rate of 0 % but is on the EU blacklist exposes its French resident to a risk of tax reassessment greater than the expected gain. Articles that rank the “best countries to pay less tax” without mentioning this regulatory filter omit a determining criterion.
Impatriate regimes in Europe: Italy and Portugal versus France
Several European countries have created targeted tax regimes to attract high foreign incomes, without eliminating income tax.
The Italian case
Italy offers a flat tax on foreign-source income for new tax residents. This system is particularly suited for taxpayers receiving passive income (dividends, capital gains, rents) outside of Italy. Inheritance tax on direct line is set at 4 % after a deduction of one million euros, compared to a rate that can reach 45 % in France beyond 1.8 million euros.
Portugal after the NHR
The Portuguese Non-Habitual Resident regime, long a reference for French retirees, has been significantly restructured. Portugal has introduced a new system called IFICI, aimed at qualified professionals and researchers. The eligibility conditions are more restrictive than the former NHR, and the tax advantage focuses on certain categories of professional income.
In contrast, France has no comparable regime to attract wealthy foreign tax residents. The French impatriate regime exists, but its conditions and scope remain significantly more limited.
Actual taxation versus displayed taxation: what weighs in the balance
A nominal tax rate does not reflect the total tax burden borne. Several elements modify the final calculation.
The bilateral tax treaty between France and the host country determines which state taxes what. Without a treaty (as in the case of some micro-states), the risk of double taxation is real. With a poorly calibrated treaty, some income remains taxable in France even after departure.
Social contributions constitute another often underestimated item. A country without income tax but with high social contributions or almost non-existent health coverage forces one to take out expensive private insurance. The overall cost of social protection must be included in the calculation.
Regulatory stability also matters. Bulgaria has a 10 % income tax and 10 % corporate tax, among the lowest in Europe. Andorra is at the same level. These rates have not changed for several years, providing predictability that temporary regimes (like Italian impatriates) do not guarantee in the long term.
Analyzing the favorable taxation of a country is not limited to a ranking of rates. The European blacklist, the evolution of special regimes like the Portuguese NHR transformed into IFICI, and the introduction of corporate tax in the United Arab Emirates show that the international tax landscape is tightening. The most reliable parameter remains the combination of a solid tax treaty, controlled overall effective rate, and absence of the jurisdiction from European monitoring lists.
