Luxembourg Life Insurance and Estate Transfer: Complete Guide

Why consider a Luxembourg policy for estate transfer?

The Grand Duchy of Luxembourg is Europe's leading life insurance hub, with over 200 billion euros in assets managed by companies authorised by the Commissariat aux Assurances (CAA). For French residents with substantial assets, a Luxembourg-domiciled life insurance policy is a particularly relevant estate transfer tool. It provides no additional tax advantage over a French policy, but offers unmatched capital protection and investment flexibility.

The Luxembourg policy is primarily aimed at savers whose financial assets exceed 250,000 euros and who seek enhanced capital protection or have an international dimension to their family situation. Contrary to a persistent misconception, this is in no way a tax evasion tool: transparency is total and the automatic exchange of information between France and Luxembourg has been operating for several years.

The relevance of the Luxembourg policy in an estate transfer strategy rests on three fundamental pillars: structural asset protection, management flexibility and international portability. These three characteristics, combined with the vehicle's tax neutrality, make it an indispensable complement for substantial estates and cross-border families.

The triangle of security: a protection unique in Europe

The tripartite mechanism

The protection of Luxembourg policyholders rests on a mechanism called the triangle of security (triangle de securite), which involves three parties bound by an agreement:

1. The insurance company that issues the policy and manages the relationship with the policyholder
2. The approved custodian bank that holds the assets in a separate account, legally distinct from the insurance company's balance sheet
3. The Commissariat aux Assurances (CAA) that supervises the entire arrangement, approves the custodian bank and can freeze assets in the event of difficulties with the insurer

This institutional mechanism is unique in Europe. It is based on the Luxembourg law of 7 December 2015 on the insurance sector, which mandates this asset segregation. Policyholders' funds are physically separated from the insurance company's own assets and deposited in identified accounts at the custodian bank. In the event of financial difficulties for the insurer, the CAA has the power to intervene immediately: it can freeze assets held at the custodian bank, preventing any transfer to the company's creditors.

The policyholder super-privilege

In the event of the insurance company's insolvency, Luxembourg policyholders benefit from first-rank creditor status (super-privilege). They are repaid before any other creditor, including the Luxembourg state, employees and secured creditors. This super-privilege is absolute and unlimited: regardless of the amount held in the policy, the entirety is protected.

Tax neutrality: no advantage, no disadvantage

Luxembourg applies the principle of tax neutrality: the policy is fiscally transparent. The legislation of the policyholder's country of residence applies in full, both for the taxation of withdrawals and for the estate transfer tax treatment.

For a French tax resident, a Luxembourg policy is subject to the same rules as a French policy:

• Article 990 I of the CGI for premiums paid before age 70: 152,500-euro allowance per beneficiary, then taxation at 20% up to 700,000 euros and 31.25% beyond
• Article 757 B of the CGI for premiums paid after age 70: overall allowance of 30,500 euros, then taxation at standard inheritance tax rates
• Full exemption for the surviving spouse and PACS partner, in accordance with the loi TEPA of 21 August 2007

How the two tax regimes interact

It is essential to understand the boundary between the two regimes clearly. The 70th birthday is the dividing line: premiums paid before that date fall under Article 990 I of the CGI (flat-rate regime with a 152,500-euro per-beneficiary allowance), while those paid after fall under Article 757 B of the CGI (overall 30,500-euro allowance shared among all beneficiaries, then inheritance tax based on the family relationship). This distinction applies identically whether the policy is French or Luxembourg-domiciled.

Identical transfer example

A 65-year-old policyholder contributes 500,000 euros to a policy and designates their two children as equal beneficiaries. At death, the policy is worth 750,000 euros thanks to compounded interest. Each child receives 375,000 euros. Since the contribution was made before age 70, Article 990 I of the CGI applies.

The tax treatment is strictly identical. The appeal of the Luxembourg policy lies in its protection and management features, not in any tax advantage. This is a fundamental point that every potential policyholder must grasp before looking to Luxembourg.

Advantages for international estate transfer

Policy portability

The major advantage of the Luxembourg policy is its international portability. If the policyholder changes their country of residence, the policy automatically adapts to the new country's tax regime, without transfer or new subscription. Luxembourg companies hold authorisations allowing them to operate on a freedom-of-services basis throughout the European Economic Area and in many third countries.

In practical terms, a French policyholder who relocates to Belgium, Italy or Portugal keeps their Luxembourg policy. The company adapts the contractual terms to local regulations and the tax regime of the new country of residence applies automatically. With a French policy, such mobility would be far more complex, or even impossible without surrendering the policy and taking out a new one.

Example: Marie, a French resident, takes out a Luxembourg policy at 55 with 800,000 euros. At 65, she moves to Portugal. At her death at 82, the applicable tax treatment is that of Portugal (which does not levy inheritance tax in the direct line). Her children recover the entire capital without taxation, provided they are not French tax residents within the meaning of Article 990 I of the CGI (condition of six years' residence in France out of the last ten).

International beneficiary clauses

Luxembourg companies have expertise in drafting beneficiary clauses tailored to international situations:

• Beneficiaries residing in several different countries
• Split clauses (demembrement) with elements of private international law
• Designation of Anglo-Saxon trusts or foundations as beneficiaries
• Clauses with conditions precedent or subsequent linked to tax residency
• Option clauses allowing beneficiaries to choose between different ways of receiving the capital

This expertise is particularly valuable for blended families with an international dimension, where civil law and tax considerations intersect across multiple jurisdictions.

Multi-currency management

The Luxembourg policy allows assets to be held in several currencies (euro, dollar, Swiss franc, pound sterling, yen). This feature is valuable when beneficiaries reside in different currency zones, as it avoids exchange rate risk at the time of settlement. A beneficiary residing in the United States could receive their capital directly in dollars, without any currency conversion.

Dedicated funds: bespoke management

The Luxembourg policy gives access to investment vehicles unavailable in standard French policies. This investment flexibility is one of the main attractions of the policy for substantial estates.

The different fund categories

The Fonds interne dedie (FID), or dedicated internal fund, accessible from 250,000 euros, offers bespoke management with a manager chosen by the policyholder. The management mandate is fully personalised: the policyholder defines their risk profile, performance targets and investment constraints. The selected manager (private bank, independent asset management firm) implements the strategy within the life insurance wrapper.

The Fonds interne collectif (FIC), or collective internal fund, accessible from 125,000 euros, offers pooled management among several policyholders sharing the same profile and objectives. It provides access to professional management at a lower cost, while benefiting from the diversification of pooling.

The Fonds d'assurance specialise (FAS), or specialised insurance fund, reserved for assets exceeding 2,500,000 euros, opens access to asset classes unavailable in standard policies: private equity, private debt, unlisted real estate, infrastructure. This vehicle is particularly suited to sophisticated investors seeking to diversify their estate beyond traditional financial markets.

Worked illustration: a 500,000-euro contribution at age 60, invested in a dedicated fund at an annualised return of 5%, would reach approximately 1,327,000 euros after 20 years. The same amount placed in a euro fund (fonds en euros) at 2.5% would be worth only 820,000 euros. The 507,000-euro difference is transferred under the same favourable tax conditions, under Article 990 I of the CGI if the contribution was made before age 70. Over a 20-year horizon, the choice of management approach has a considerable impact on the amount actually transferred to beneficiaries.

Entry conditions and fees

Entry thresholds

Luxembourg policies are aimed at a wealth management clientele. Minimum subscription amounts vary by company:

• Entry level (euro fund + standard unit-linked funds): 250,000 euros minimum
• Mid-range (with FID): 500,000 euros minimum depending on the company
• High-end (with FAS): 2,500,000 euros minimum

These thresholds are commercial, not regulatory: each company freely sets its own minimums. Some companies offer entry thresholds from 125,000 euros for standard unit-linked policies, while others require a minimum of 1,000,000 euros for FID access.

Fee structure

The fees on a Luxembourg policy are generally higher than those on an online French policy, but comparable to those of a French private banking policy. Entry fees range from 0% to 2% (often negotiable), annual policy management fees from 0.50% to 1.00%, dedicated fund fees from 0.30% to 1.00% per year, and custodian bank fees from 0.05% to 0.30% per year. In total, annual fees fall between 1.00% and 2.30% per year.

Cumulative fees are often higher than those of an online French policy (0.50% to 0.75% per year), but the enhanced protection and access to dedicated funds justify this gap for substantial estates. For a 1,000,000-euro policy, the annual fee difference represents between 2,500 and 15,500 euros. This difference must be weighed against the additional protection: if the estate exceeds 70,000 euros (the FGAP ceiling in France), the Luxembourg super-privilege covers a risk that the French policy does not.

Choosing the company and custodian

The main market players

The Luxembourg life insurance market has around twenty active companies, including subsidiaries of major European groups and independent operators. The companies most active in the French market are subsidiaries of French, Belgian, Italian or Swiss groups. The choice of company should be based on several criteria: financial strength (rating agency scores), expertise in dedicated fund management, quality of client service and distribution network in France.

The custodian bank

The custodian bank plays a central role in the triangle of security. It must be approved by the CAA and comply with strict asset segregation requirements. The policyholder sometimes has the option of choosing their custodian bank from among those with which the company has signed agreements. This choice can influence the investment universe available and the quality of reporting.

Points to watch

Reporting obligation

Every French resident holding a Luxembourg policy must declare it each year via form 3916 bis attached to their income tax return. Failure to declare carries a fine of 1,500 euros per policy (increased to 10,000 euros if the company is located in a non-cooperative state, which is not the case for Luxembourg).

No tax advantage

A Luxembourg policy does not allow you to evade French tax. Any attempt at concealment constitutes tax fraud carrying criminal penalties. The automatic exchange of information (CRS standard) enables the French tax authorities to know of the existence of policies held in Luxembourg. Premiums paid before age 70 are subject to the Article 990 I levy, and those paid after age 70 to the Article 757 B regime, exactly as for a French policy.

Opportunity cost

The additional fees of the Luxembourg policy compared with an online French policy must be weighed against the actual benefits. For a 250,000-euro estate (minimum threshold), the additional cost can represent 1,250 to 3,875 euros per year. If the policyholder has no international dimension and their assets do not significantly exceed the FGAP ceiling (70,000 euros), a French policy may be more suitable. The Luxembourg policy comes into its own from 500,000 euros of financial assets, and becomes virtually essential beyond 1,000,000 euros for the security it provides.

Conclusion

The Luxembourg life insurance policy is not a tax avoidance tool but a first-class vehicle for estate protection and transfer. Its triangle of security, super-privilege, tax neutrality and international portability make it the natural choice for estates exceeding 250,000 euros and families with international ties. The estate transfer tax treatment remains identical to that of a French policy -- Article 990 I of the CGI for premiums paid before age 70 with a 152,500-euro per-beneficiary allowance, Article 757 B of the CGI for premiums paid after age 70 with an overall 30,500-euro allowance -- but the security of capital and the diversification of investment supports are significantly superior. For substantial estates and families with an international dimension, the Luxembourg policy constitutes an essential pillar of any estate transfer strategy.
