Cross-Border Wealth Management in France: What High-Net-Worth Expats Need to Consider

France offers an attractive combination of culture, infrastructure, healthcare and lifestyle. From Paris and the Côte d’Azur to Provence and the French Alps, the country continues to appeal to international entrepreneurs, senior professionals, retirees and high-net-worth families.

However, moving to France can fundamentally change how your worldwide income, investments, property and estate are treated. A portfolio that was appropriate while living in the UK, US, Switzerland or another jurisdiction may become inefficient—or create additional reporting obligations—once you become resident in France.

Cross-border wealth management in France may involve more than selecting investments. Relevant considerations can include tax residency, investment planning, pensions, property, succession and currency exposure within a single international strategy.

Establishing Your French Tax Residency

One of the first priorities is determining when you become tax resident in France.

French tax residence is not decided solely by counting days. The authorities may consider where your household or main home is located, where you undertake your principal professional activity and where your centre of economic interests lies. International tax treaties can also affect the final position where two countries consider you resident under their domestic rules.

Although spending at least 183 days in France can be relevant, it is not the only test. A person may potentially become French tax resident even when they spend fewer than 183 days in the country.

Once classified as a French tax resident, you will generally be subject to French taxation on income from French and overseas sources, subject to the provisions of applicable tax treaties. This can include:

• Employment and self-employment income
• Dividends and interest
• Rental income
• Pension income
• Investment gains
• Income from trusts, companies and other structures

France’s tax-treaty network can help determine which country has primary taxing rights and how relief from double taxation may be available. However, a treaty does not necessarily mean that foreign income can be omitted from a French return. French residents may still need to declare overseas income even when it is ultimately taxed elsewhere or exempted with progression. The French tax authority provides further guidance on the treatment of foreign-source income.

Why Pre-Arrival Wealth Planning Matters

For high-net-worth individuals moving to France, timing can have a significant impact.

Selling an asset, restructuring a company, taking a pension withdrawal or realising an investment gain shortly before or after becoming resident can produce very different outcomes. That does not mean action should automatically be taken before relocating. It means each decision should be assessed within the relevant French and overseas tax rules.

A pre-arrival review may include:

• Current and expected tax residence
• Investment portfolios and ownership structures
• Pensions and retirement accounts
• Private companies and shareholdings
• Trusts, foundations and family investment vehicles
• Residential and investment property
• Existing life insurance and investment bonds
• Wills, gifts and succession arrangements
• Future liquidity and income requirements

Ideally, this work should begin well before the move. If you already live in France, a coordinated review can still identify unnecessary complexity, concentration risk or structures that no longer align with your circumstances.

Reviewing Overseas Investments After Moving to France

Internationally mobile families often arrive in France with investments accumulated across several countries. These might include UK ISAs, offshore bonds, brokerage accounts, collective investments, US retirement plans or portfolios held through private banks.

The tax advantages associated with an account in its country of origin may not automatically be recognised in France. An investment described as “tax-free” or “tax-efficient” in one country could still generate taxable income or gains for a French resident.

The underlying assets also matter. Two portfolios with similar market exposure may be treated differently because of their legal structure, location or method of ownership.

Factors that may form part of a review include:

• French taxation of income, gains and withdrawals
• Availability of tax credits under the relevant treaty
• Whether the investment creates annual reporting requirements
• Costs, liquidity and surrender conditions
• Currency exposure
• Investment diversification
• Estate-planning implications
• Whether the provider can continue servicing a French resident

The objective is not necessarily to replace every overseas arrangement. It is to understand how each asset fits into the investor’s new cross-border position.

Declaring Foreign Accounts and Policies

French residents can have extensive disclosure responsibilities relating to assets held abroad.

Foreign bank and investment accounts may need to be declared, including accounts opened, held, used or closed during the relevant year. Certain overseas life insurance and capitalisation contracts also require disclosure. Digital-asset accounts may create additional obligations.

The French tax authority confirms that foreign accounts and overseas life insurance policies can fall within these reporting rules. Failure to make the required declarations may result in penalties, even where the account has generated little or no taxable income. Official guidance is available from the French tax administration.

For high-net-worth families with multiple custodians, legacy accounts and international entities, maintaining an accurate asset register is particularly important.

Understanding French Real Estate Wealth Tax

Property frequently represents a substantial part of an internationally mobile family’s wealth.

France’s Impôt sur la Fortune Immobilière, or IFI, applies where the net taxable value of relevant real-estate wealth exceeds the applicable threshold. For 2026, the entry threshold is €1.3 million. The regime can include property held directly and certain real-estate interests held indirectly through companies, funds or other investment structures. Service Public explains the current IFI threshold and calculation.

Residence status, length of French residence, property location, ownership structure, debt and any available exemptions can influence the position. Borrowing does not always produce a straightforward deduction, and valuations need to be supportable.

Before purchasing French property—or retaining substantial property overseas—HNWI families may need to examine the potential IFI exposure alongside income tax, capital gains, succession and liquidity considerations.

Coordinating Pensions and Retirement Income

Cross-border pension planning is rarely just about investment performance.

Different types of pension income may receive different treatment under France’s tax treaties. Government-service pensions, private pensions, lump sums and retirement accounts can each require separate analysis. A withdrawal that appears attractive under the rules of the originating country may create an unexpected French liability.

Currency exposure can also be relevant. If your retirement expenditure is mainly in euros but your pension assets are denominated in sterling or US dollars, exchange-rate movements can affect the value of available income.

Retirement planning considerations may include timing of withdrawals, tax treatment, investment risk and currency requirements rather than considering each pension in isolation.

Estate Planning Across Borders

French succession planning can affect both who inherits and the amount of inheritance tax that may be payable. Nationality, residence, the location of assets, family relationships, wills, matrimonial property arrangements and beneficiary clauses may all be relevant.

For blended families, unmarried couples and families with beneficiaries in several countries, the position can be especially complex. A will prepared in another jurisdiction may not necessarily produce the intended result in France.

Estate planning may need to be reviewed alongside property ownership, lifetime gifting, liquidity and appropriate life assurance or investment structures. Legal, tax and financial advisers may need to work together across the relevant jurisdictions.

Build One Coordinated Cross-Border Strategy

For high-net-worth expats, one of the risks is often fragmented advice. A French accountant may understand the domestic tax return, while an overseas investment manager focuses on the portfolio and a solicitor considers the will. Without coordination, important interactions can be overlooked.

A cross-border wealth plan should bring these areas together and be reviewed as your residence, family circumstances, legislation and long-term objectives evolve.
