If you own real estate assets connected to France — whether you're a resident or a non-resident — you may be subject to the France wealth tax, officially known as the Impôt sur la Fortune Immobilière (IFI). This guide covers everything you need to know about the wealth tax in France for the 2025/2026 tax year, including current rates, thresholds, exemptions, filing deadlines, and practical strategies to manage your liability.

France's wealth tax applies specifically to real estate holdings and can catch both long-term residents and foreign property investors off guard. Understanding how it works is essential for effective tax planning.

What Is the France Wealth Tax (IFI)?

The Impôt sur la Fortune Immobilière (IFI) is France's current wealth tax, introduced on January 1, 2018, replacing the broader Impôt de Solidarité sur la Fortune (ISF). While the old ISF taxed all types of wealth — including financial investments, art, and luxury goods — the IFI focuses exclusively on real estate assets.

The key distinction matters: stocks, bonds, bank accounts, life insurance policies, furniture, vehicles, and other non-real-estate assets are not subject to the IFI. This narrower scope was designed to encourage investment in the French economy while still taxing high-value property holdings.

Who Is Subject to the IFI?

The IFI applies to:

  • French tax residents whose worldwide net real estate assets exceed €1,300,000 as of January 1 of the tax year
  • Non-residents whose net real estate assets located in France exceed the same €1,300,000 threshold

The tax is assessed per tax household (foyer fiscal), meaning married couples and civil partners (PACSés) combine their real estate holdings for the purposes of the threshold and rate calculation. Minor children's real estate assets are also included in the parents' declaration.

France Wealth Tax Rates for 2025/2026

The IFI uses a progressive rate structure applied to the net taxable value of your real estate assets. Although the threshold for being subject to IFI is €1,300,000, once you cross that threshold, taxation begins at €800,000 — an important nuance that catches many taxpayers by surprise.

Here are the France tax rates 2025/2026 for the IFI:

Net Taxable Real Estate Value Tax Rate
Up to €800,000 0%
€800,001 – €1,300,000 0.50%
€1,300,001 – €2,570,000 0.70%
€2,570,001 – €5,000,000 1.00%
€5,000,001 – €10,000,000 1.25%
Above €10,000,000 1.50%

How the Threshold and Rates Interact

This is one of the most common misconceptions about the wealth tax in France: the filing threshold and the taxation starting point are different.

  • Filing threshold: €1,300,000. If your net real estate assets are below this figure, you owe nothing and do not need to file.
  • Taxation starting point: €800,000. Once your assets exceed €1,300,000, the progressive rates apply starting from €800,000.

Practical Example:

Suppose your net real estate assets are valued at €1,500,000 on January 1, 2025.

  1. The first €800,000 is taxed at 0% = €0
  2. From €800,001 to €1,300,000 (€500,000) taxed at 0.50% = €2,500
  3. From €1,300,001 to €1,500,000 (€200,000) taxed at 0.70% = €1,400
  4. Total IFI liability = €3,900

Smoothing Mechanism (Décote)

For taxpayers whose net real estate assets fall between €1,300,000 and €1,400,000, a smoothing mechanism (known as a décote) applies to soften the tax burden at the entry point. The discount is calculated as:

Décote = €17,500 – (1.25% × Net Taxable Value)

For example, if your net real estate assets are €1,350,000:

  • Calculated IFI (before décote): €2,500 + €350 = €2,850
  • Décote: €17,500 – (1.25% × €1,350,000) = €17,500 – €16,875 = €625
  • Net IFI after décote: €2,225

This mechanism ensures a gradual entry into the tax rather than a sharp cliff effect.

What Assets Are Included in the IFI?

Understanding which assets count toward your IFI liability is critical for accurate reporting and effective planning.

Taxable Real Estate Assets

The following are included in the IFI calculation:

  • Directly owned property: Primary residences, secondary residences, rental properties, and vacant land located in France (for residents, worldwide real estate)
  • Indirectly held real estate: Shares in companies or funds (including SCIs, OPCIs, and certain real estate investment trusts) to the extent they represent underlying real estate assets
  • Real estate rights: Usufruct (usufruit), bare ownership (nue-propriété), leasehold rights, and building rights
  • Property under construction: Ongoing real estate development projects
  • Rural and forestry land: Although partial exemptions may apply (see below)

Assets Excluded from the IFI

The following are not subject to the wealth tax in France:

  • Financial assets (stocks, bonds, bank deposits)
  • Life insurance policies (assurance-vie), except for the real estate component within unit-linked policies
  • Business assets, furniture, vehicles, art, and jewelry
  • Professional real estate (property used for your business activity — see below)

The Primary Residence Discount

One of the most significant IFI benefits is the 30% abatement on your primary residence. If your main home is valued at €2,000,000, only €1,400,000 is included in your IFI calculation.

This discount:

  • Applies automatically
  • Cannot be combined with other property-specific deductions
  • Only applies to the property you genuinely occupy as your main home on January 1

Key Exemptions and Deductions

Professional Property Exemption

Real estate used for your professional activity is fully exempt from the IFI. This includes:

  • Offices, factories, or workshops you own and use for your business
  • Agricultural land you farm yourself
  • Property used by a company in which you hold a significant management role and ownership stake

To qualify, you must be able to demonstrate that the property is essential to and primarily used for the professional activity.

Forestry and Rural Property Exemptions

Certain rural and forestry assets benefit from partial exemptions:

  • Woodland: 75% exemption if subject to a sustainable management plan
  • Rural property leased long-term: 75% exemption up to €101,897 and 50% beyond that threshold
  • Shares in forestry investment groups (GFF): 75% exemption under specific conditions

Deductible Liabilities

You can deduct certain debts from your gross real estate value to arrive at your net taxable base. Deductible liabilities include:

  • Mortgages on taxable properties (subject to limitations for loans exceeding €5 million — a progressive restriction applies)
  • Property taxes (taxe foncière) due on January 1
  • Renovation or improvement costs that constitute a debt on the valuation date
  • Acquisition debts for taxable real estate

Important limitation: Since the 2018 reform, deductible debts relating to real estate acquired through loans exceeding €5,000,000 are subject to a degressive cap, reducing the deduction for very high-value leveraged purchases.

IFI Cap (Plafonnement)

French tax law provides an important safeguard: the combined total of your IFI and income taxes (including social contributions) cannot exceed 75% of your net income for the previous year. If it does, the excess IFI is reduced accordingly.

This cap prevents the wealth tax from becoming confiscatory, although the calculation is complex and often requires professional assistance.

Filing Requirements and Deadlines

How to File

The IFI is declared alongside your annual income tax return using Form 2042-IFI (an annex to the standard income tax declaration). The declaration includes:

  • A detailed listing of all taxable real estate assets and their valuations
  • Deductible liabilities
  • Any applicable exemptions or reductions

For non-residents without French income, the IFI can be declared using Form 2042-IFI-CON submitted independently.

Filing Deadlines for 2025

The IFI follows the same filing calendar as the French income tax return. For the 2025 filing season (declaring assets as of January 1, 2025):

  • Paper returns: Mid-May 2025 (exact date published annually by the Direction Générale des Finances Publiques)
  • Online returns: Late May to early June 2025, depending on your department of residence:
    • Departments 01–19 and non-residents: Typically late May
    • Departments 20–54: Typically early June
    • Departments 55–976: Typically mid-June

Online filing is mandatory for all taxpayers with internet access.

Valuation Date

All real estate assets are valued at their fair market value (valeur vénale) as of January 1 of the tax year. This is the price the property could reasonably fetch in an arm's-length transaction on the open market on that date.

IFI for Non-Residents and International Considerations

The France wealth tax has significant implications for non-residents who own French property.

Non-Resident Tax Base

Non-residents are only taxed on their French-situs real estate — property physically located in France or shares in entities whose assets are predominantly French real estate. Worldwide real estate outside France is excluded.

However, non-residents do not benefit from the 30% primary residence abatement on French property, since their primary residence is outside France.

Double Taxation Treaties

France has an extensive network of double taxation agreements (DTAs) that can affect IFI liability. Most French treaties allocate taxing rights over real estate to the country where the property is situated (the situs country). This means:

  • France generally retains the right to tax real estate located on its territory, regardless of the owner's country of residence
  • If your home country also imposes a wealth tax on foreign real estate, the treaty may provide a tax credit or exemption to avoid double taxation

Countries with their own wealth taxes (e.g., Spain, Norway, Switzerland) may have specific treaty provisions addressing overlapping wealth tax claims. Always review the applicable bilateral treaty.

The Six-Year Rule

New arrivals to France benefit from a favorable regime: for the first five years of French tax residence, you are only taxed on French-situs real estate (like a non-resident), not on your worldwide real estate. From the sixth year onward, you become liable on your global real estate holdings.

This can represent significant tax planning opportunities for expatriates moving to France.

Common Mistakes and Tax Planning Tips

Mistakes to Avoid

  1. Undervaluing properties: The French tax authorities (fisc) have access to property transaction databases and will challenge valuations that appear significantly below market value. Penalties of up to 40% can apply for deliberate undervaluation.

  2. Forgetting indirect holdings: Shares in real estate companies (SCIs, REITs) must be included to the extent of their real estate component. Many taxpayers overlook this.

  3. Ignoring the €1,300,000 threshold: Some property owners assume they're not affected, but fail to account for the combined value of all their real estate, including foreign properties (for residents).

  4. Claiming the primary residence abatement incorrectly: If you have two homes and split your time between them, only one qualifies for the 30% discount — and the tax authorities may scrutinize which one truly constitutes your main residence.

  5. Failing to account for usufruct: Complex ownership structures involving usufruct and bare ownership have specific IFI rules that differ from standard property valuation.

Tax Planning Strategies

  • Donate bare ownership (nue-propriété): Retaining usufruct while donating bare ownership to your children can reduce the IFI-taxable value, since the usufructuary typically bears the IFI but at a reduced valuation based on their age.
  • Invest in exempt assets: Shifting wealth from real estate into financial assets (which are IFI-exempt) can reduce your taxable base.
  • Use professional property exemptions: Ensure any property genuinely used for business purposes is properly declared as exempt.
  • Leverage the IFI cap: High-income taxpayers should model the 75% cap to determine whether it provides relief.
  • Charitable donations: Donations to qualifying public-interest organizations can reduce your IFI by 75% of the donation amount, up to a maximum reduction of €50,000 per year.

Frequently Asked Questions (FAQ)

Is there still a wealth tax in France?

Yes. France replaced the broad-based ISF with the narrower IFI (Impôt sur la Fortune Immobilière) in 2018. The IFI specifically targets real estate wealth above €1,300,000 in net value.

Does the IFI apply to non-residents?

Yes. Non-residents who own real estate in France with a net value exceeding €1,300,000 are subject to the IFI on their French-situs property only.

Is my primary residence taxed under the IFI?

Yes, but it benefits from a 30% reduction in its taxable value. A home valued at €2,000,000 would only count as €1,400,000 for IFI purposes.

Can I deduct my mortgage from the IFI?

Yes, outstanding mortgage balances on taxable properties are generally deductible, though a progressive limitation applies for debts exceeding €5,000,000.

What happens if my assets are just above the threshold?

If your net real estate assets are between €1,300,000 and €1,400,000, a smoothing mechanism (décote) reduces your IFI liability to ease the transition.

How do I value my properties for IFI?

Properties should be valued at their fair market value (valeur vénale) as of January 1 of the tax year. This means the price the property would fetch in an arm's-length sale on the open market. Professional valuations are recommended for high-value or unusual properties.
