Key Points

Understanding inheritance tax in 2026: allowances, rates and changes

To effectively manage the transfer of your assets, you must first master the relevant vocabulary and mechanisms. Let's start with the fundamentals.

The dejection refers to the amount deducted from the value of the assets transferred before the application of inheritance tax. The scale The progressive tax schedule determines the tax rate based on the remaining taxable portion. These two concepts are central to any inheritance strategy.

In 2026, French rules maintain a generally stable framework, while incorporating certain developments stemming from the tax measures of Law 2026. L'’abatement of €100,000 per child remains the central reference for direct line successions, but its practical application deserves attention.

Allowances and rates: the 2026 reference table

This inheritance tax scale 2026 This applies after deduction of the allowance. A family with two children inheriting an estate of €500,000 will thus benefit from a total allowance of €200,000, leaving only €300,000 subject to taxation.

What this actually changes for families

Key developments to remember for 2026:

• The dejection of €100,000 per child applies every 15 years, which opens up the possibility of repeated early gifts.
• THE surviving spouses remain exempt from inheritance tax in France, regardless of the amount.
• The time frame of tax reminder remains fixed at 15 years: any prior gift of more than 15 years is totally cleared.
• THE transmissions between brothers and sisters remain taxed at high rates (35 to 45 %), highlighting the importance of anticipating.

For international families, the situation is more complicated. An expatriate residing in the United Arab Emirates or Switzerland may be subject to French inheritance tax if their real estate is located in France, even if they no longer reside there. This is precisely why optimize the transfer of assets requires a comprehensive, not fragmented, analysis.

Key figure: For an inheritance of €2,000,000 with two children, the savings achieved through a well-structured advance gift can exceed €150,000 compared to a gross transfer without anticipation.

Specifics of blended and expatriate families: tax breaks, rules and tips

Blended families today represent a complex reality in terms of inheritance, which French lawmakers have partially addressed. The year 2026 marks a significant step forward with the introduction of a specific tax allowance for stepchildren.

The tax allowance for stepchildren: a significant new development

Since 2026, a tax allowance of €15,932 applies to transfers to the children of a spouse in blended families. This allowance is subject to a cohabitation requirement: the two adults must have lived together for at least 10 years, and the stepparent must not have adopted the child (in which case the rules of legal parentage apply).

Here is a comparison of the situations before and after optimization for a blended family:

The difference between a biological child and a stepchild remains significant. However, the €15,932 allowance represents a substantial improvement compared to the previous situation where there was no recognition at all. For some families, a simple adoption could be an alternative worth seriously considering.

The specific case of expatriates

For an international household, tax residency rules play a crucial role. A parent residing in Singapore who transfers a Parisian apartment to their child living in London will be subject to French tax on that real estate asset. But if the transfer involves financial assets held outside France, the international wealth management opens up significant optimization opportunities.

Common pitfalls include:

• Dual tax residency : some taxpayers think they have left France for tax purposes while criteria for continued residence still exist.
• The absence of a bilateral agreement : not all countries are linked to France by an inheritance tax treaty, which exposes them to actual double taxation.
• Evidence of cohabitation Insufficient for stepchildren, which could invalidate the tax allowance in the event of an audit. wealth survey Having a professional prepare a case can sometimes be useful in building a strong case.

Pro tip: If you reside in a country that has signed an inheritance tax treaty with France (Germany, Switzerland, the United States, and the United Kingdom, in particular), systematically analyze the tax credit mechanism provided for by this treaty before any significant transfer of assets. wealth management advice 2026 This objective will allow you to identify applicable tax credits and avoid paying twice.

Concrete strategies to optimize your family wealth in 2026

Knowing the rules is not enough. You need to translate them into a structured action plan, adapted to your family, geographical and financial situation.

Key steps to a successful succession strategy

1. To carry out a asset audit complete : to map all assets, their location, their tax status and the family links involved.
2. Planning advance gifts : use the €100,000 allowance per child now to clear the tax liability in 15 years and start again.
3. Using a shared gift : this mechanism allows the value of the assets to be fixed on the day of the gift, thus protecting the beneficiaries from a future revaluation.
4. Optimizing assurance-vie Contracts taken out before the age of 70 benefit from a tax allowance of €152,500 per beneficiary, excluding inheritance, making it an essential tool.
5. Establish a quasi-usufruct : this technique allows the donor to retain the use of a sum of money while transferring the bare ownership, reducing the taxable base.

«At Balmont Conseil, we regularly observe that well-organized families reduce their inheritance tax burden by 30 to 50% thanks to planning that begins 10 to 15 years before the transfer.» — Alexis Sagnier, founder of Balmont Conseil

Numerical example: before and after optimization

THE transmission tools Many solutions are available, but their effectiveness depends on their intelligent combination and timely implementation. tax audit transfer allows you to identify the levers best suited to your situation.

For situations where family composition is uncertain or potential beneficiaries are unknown, recourse to a search for heirs in the estate may prove necessary before structuring the transmission.

Pro tip: The 15-year period is often underestimated. Start your gifts today: even a modest first payment of €30,000 per child starts the clock ticking and will allow you to pass on an additional €100,000 tax-free in 15 years.

International tax management: mitigating the risks of double taxation

For expatriates and families whose assets are spread across multiple countries, the risk of double inheritance tax is real and often underestimated. The good news: mechanisms exist to limit it, provided they are activated at the right time.

The principles of international inheritance taxation

Expatriates are subject to specific cross-border transfer rules that depend on several cumulative criteria: the tax residence of the deceased, the tax residence of the heirs, and the location of the assets transferred.

Here are the most common situations:

• Deceased resident of France, heir abroad : French rights applicable to the entire world wealth.
• Deceased non-resident, heir in France : French rights applicable to assets located in France, and potentially to certain foreign assets if the heir has been a French resident for more than 6 years out of the last 10 years.
• Both the deceased and the heir were non-residents. : French rights only on French real estate.

Bilateral agreements: your first line of defense

France has concluded inheritance tax treaties with around twenty countries. These agreements generally allow for the deduction of taxes paid abroad from those owed in France, thus avoiding double taxation. The countries covered include, in particular, the United States, Germany, Switzerland, Spain, and the United Kingdom.

For residents of countries without a treaty (Emirates, Singapore, Hong Kong), structures such as asset holdings, THE Anglo-Saxon trusts or the cross-border division of property rights These may constitute relevant alternatives. Each solution presents advantages and legal constraints that must be assessed on a case-by-case basis, taking into account the applicable 2026 rates.

There taxation of non-residents In France, it is a particularly technical field, where an analytical error can be very costly.

Pro tip: Have your international wealth situation audited annually, especially whenever you change your residence. Moving from Paris to Dubai, for example, can generate unforeseen tax implications for your estate if your departure from France hasn't been properly planned.

Why anticipating becomes essential in 2026: real consequences of being late

One of the most costly mistakes we see at Balmont Conseil isn't a bad decision: it's the lack of a decision. Waiting for the "right window" to plan your business transfer often means missing out on tax breaks that could have been applied twice over 30 years.

Let's take a concrete example. A family that made its first gift in 2011 could have repeated the process in 2026, again benefiting from a total allowance of €100,000 per child. If they waited until 2026 to make their first gift, they will have to wait until 2041 for the next tax break. The cost of inaction is measured in decades, not years.

Changes in tax residence also generate side effects that few families anticipate. A taxpayer who leaves France without having settled their outstanding inheritance obligations may find themselves subject to...’exit tax on certain assets, or seeing one's heirs exposed to cross-taxation between two countries. Regulatory complexity does not simplify over time: it accumulates.

Preparing for the next generation is a long-term undertaking. A strategic wealth analysis conducted today provides visibility over 15 to 20 years and allows the plan to be adapted to each stage of life: the birth of a child, expatriation, business sale, or inheritance. By 2026, family wealth planning will no longer be a luxury reserved for the very wealthy; it will be a responsible investment practice.
