If you own real estate in France or hold significant property assets worldwide as a French tax resident, understanding how France wealth tax works is essential for your financial planning. The French wealth tax — officially known as the Impôt sur la Fortune Immobilière (IFI) — is a unique levy that specifically targets high-value real estate holdings. Whether you're a resident, an expatriate, or a non-resident property investor, the IFI can significantly affect your annual tax liability.

In this comprehensive guide, we explain how wealth tax works in France for the 2025/2026 tax year, including current rates, exemptions, filing obligations, and practical strategies to help you stay compliant and minimize your burden.

What Is the French Wealth Tax (IFI)?

The Impôt sur la Fortune Immobilière (IFI) is France's current wealth tax, which has been in effect since January 1, 2018. It replaced the former Impôt de Solidarité sur la Fortune (ISF), which taxed all types of wealth including financial assets, business holdings, and real estate.

The key difference between the ISF and the IFI is scope:

  • ISF (pre-2018): Taxed total net wealth — including financial investments, business assets, vehicles, jewelry, and real estate.
  • IFI (2018 onwards): Taxes only net real estate assets, excluding financial investments, business assets, and most movable property.

This shift was designed to encourage investment in the French economy by removing the tax burden on productive financial assets while still capturing revenue from high-value property holdings.

Who Must Pay the IFI?

The IFI applies to individuals — not companies — whose net taxable real estate assets exceed €1,300,000 as of January 1 of the tax year. Liability depends on your residency status:

  • French tax residents: Taxed on their worldwide real estate assets, including properties held directly or indirectly (through companies, trusts, etc.) anywhere in the world.
  • Non-residents: Taxed only on real estate assets located in France, including indirect holdings in French property through companies or legal structures.

Importantly, the IFI is assessed on a household basis. This means that married couples, civil partners (PACS), and cohabiting partners must combine their real estate assets when determining whether they exceed the threshold.

France Wealth Tax Rates for 2025/2026

The wealth tax rates in France follow a progressive scale. While the taxable threshold starts at €1,300,000 in net real estate assets, the actual rate calculation begins at €800,000. This creates a smoothing effect that avoids a sudden large tax bill the moment you cross the threshold.

Here are the current IFI tax brackets for the 2025/2026 tax year:

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%
Over €10,000,000 1.50%

How the Threshold and Calculation Interact

This is one of the most commonly misunderstood aspects of the French wealth tax. Here's how it works:

  1. You are only liable for the IFI if your net real estate assets are €1,300,000 or above.
  2. However, if you are liable, the tax is calculated starting from €800,000, not from €1,300,000.
  3. A discount mechanism (décote) applies to taxpayers whose net assets fall between €1,300,000 and approximately €1,400,000 to avoid a cliff-edge effect.

The discount formula is: €17,500 – (1.25% × net taxable real estate value). If the result is positive, it reduces your IFI bill.

Practical Example

Let's say your net taxable real estate assets total €2,000,000 on January 1, 2025:

  • €800,000 at 0% = €0
  • €500,000 (€800,001 to €1,300,000) at 0.50% = €2,500
  • €700,000 (€1,300,001 to €2,000,000) at 0.70% = €4,900
  • Total IFI due = €7,400

What Assets Are Taxable Under the IFI?

Understanding which assets fall within the IFI's scope is critical to accurate reporting and compliance.

Taxable Assets

The IFI covers all real estate assets held directly or indirectly, including:

  • Residential properties: Primary residences, secondary homes, vacation properties
  • Rental properties: Buy-to-let apartments, commercial real estate
  • Land and building plots: Undeveloped land, agricultural land (with some exceptions)
  • Real estate held through companies: Your proportional share of real estate assets held through SCI (Société Civile Immobilière), SCPI (Société Civile de Placement Immobilier), OPCI, REITs, and other real estate investment vehicles
  • Real estate held through trusts or foundations
  • Usufruct rights over real estate (the usufructuary is typically taxed on the full value)

Exempt Assets

The following are not subject to the IFI:

  • Financial investments: Stocks, bonds, bank deposits, life insurance (the non-real-estate portion), cryptocurrency
  • Business assets: Real estate used for professional purposes by the taxpayer (under certain conditions)
  • Forestry and rural property: Partial exemptions apply (up to 75% in some cases) for forests, rural leased land, and agricultural properties
  • Movable property: Vehicles, art, jewelry, furniture
  • Primary residence discount: A 30% reduction in the market value of your primary residence (see below)

The 30% Primary Residence Abatement

One of the most significant reliefs available under the IFI is the 30% abatement on the value of your primary residence. If your main home is worth €2,000,000, only €1,400,000 is included in your taxable base.

This abatement is automatic but only applies if the property is genuinely your principal residence. It does not apply to secondary homes or rental properties.

Deductions and Liabilities You Can Subtract

The IFI is levied on net real estate wealth, meaning you can deduct certain liabilities from your gross real estate value.

Deductible Debts

You can subtract the following from your taxable real estate base:

  • Mortgage balances on taxable properties (outstanding principal as of January 1)
  • Property taxes due (taxe foncière) on taxable properties
  • Costs of repair, maintenance, or improvement owed on taxable properties
  • Debts linked to the acquisition of taxable real estate

Restrictions on Debt Deductions

Since 2018, France has introduced anti-abuse rules to limit excessive debt deductions:

  • Bullet loans and in fine mortgages: These are only deductible on a declining basis (as if they were amortizing loans), preventing taxpayers from maintaining artificially high debt levels.
  • Related-party loans: Loans from controlled companies or family members face additional scrutiny and may be partially or fully non-deductible.
  • Debt cap: If your total taxable assets exceed €5,000,000, the deductible debt amount may be capped. Specifically, debts exceeding 60% of the taxable asset value are only 50% deductible for the portion above that threshold.

IFI for Non-Residents and Expatriates

The French wealth tax has important implications for non-residents and expatriates.

Non-Residents Owning French Property

If you are a non-resident and own real estate in France (directly or through a company), you are subject to the IFI on your French-situated real estate only. This includes:

  • Properties you own directly in France
  • Shares in French or foreign companies proportional to their French real estate holdings

Non-residents cannot claim the 30% primary residence abatement on French property unless it is genuinely their primary residence — which by definition is unlikely for non-residents.

New Arrivals to France (Expatriates)

Expatriates who become French tax residents benefit from a temporary exemption on foreign real estate:

  • During the first five tax years of French tax residency, you are only taxed on your French real estate assets for IFI purposes.
  • After five years, you become liable on your worldwide real estate holdings.

This five-year grace period is a significant planning opportunity for high-net-worth individuals relocating to France.

Double Taxation Treaties

France has an extensive network of double taxation treaties that may provide relief if you pay wealth tax or property taxes in another country. However, many treaties were negotiated before the IFI existed (when the ISF was in force), and their applicability to the IFI can be complex.

Key points to consider:

  • Most treaties allocate the right to tax real estate to the country where the property is situated.
  • Tax credits may be available to offset foreign property taxes against the IFI.
  • Professional advice is strongly recommended when cross-border real estate holdings are involved.

Filing and Payment: Key Deadlines and Process

Unlike in some countries where wealth tax is assessed separately, the IFI is declared as part of your annual income tax return in France.

How to File

  1. Report your IFI on your income tax return (form 2042-IFI), filed alongside your standard income tax declaration.
  2. Provide a detailed schedule of your real estate assets, their values, and deductible liabilities.
  3. Online filing via the impots.gouv.fr portal is mandatory for most taxpayers.

Key Deadlines for 2025

Filing deadlines for the 2025 IFI (based on assets held on January 1, 2025) typically fall in May–June 2025, aligned with income tax deadlines:

  • Paper returns (if eligible): Late May 2025
  • Online returns: Late May to mid-June 2025, depending on your département of residence
  • Non-residents: Usually the latest deadline, often mid-June 2025

The IFI amount due is included in your overall tax assessment notice and is payable according to the schedule set by the French tax authorities, typically in September–November 2025.

The IFI Cap (Plafonnement)

France applies a tax cap mechanism to ensure that total taxes (income tax + IFI + social charges) do not exceed 75% of your income. If your combined taxes exceed this threshold, your IFI is reduced accordingly.

However, this cap is calculated based on your declared income, which means taxpayers with low declared income but high real estate wealth may not benefit as much as expected.

Common Mistakes and Misconceptions

Avoiding these frequent errors can save you money and keep you on the right side of French tax law:

  • Misconception: "All my wealth is taxed." The IFI only applies to real estate assets, not financial investments, business assets, or movable property.
  • Mistake: Forgetting indirect holdings. Shares in real estate companies (SCI, SCPI, OPCI, foreign property funds) must be included proportionally.
  • Mistake: Overvaluing or undervaluing properties. The IFI uses fair market value as of January 1. Overvaluation costs you money; undervaluation risks penalties of up to 40% for deliberate under-reporting.
  • Misconception: "My mortgage eliminates my IFI." While mortgages are deductible, the anti-abuse rules (especially for in fine loans and large debts) may limit deductions.
  • Mistake: Forgetting the 30% primary residence abatement. This is one of the most valuable reliefs and should always be applied.
  • Misconception: "I'm a new expat, so I'm exempt." You're not fully exempt — you're taxed on French real estate from day one. The five-year relief only covers foreign real estate.

Frequently Asked Questions (FAQ)

What is the threshold for French wealth tax in 2025?

You are liable for the IFI if your net taxable real estate assets equal or exceed €1,300,000 as of January 1, 2025. The tax is then calculated on a progressive scale starting from €800,000.

Does the IFI apply to non-residents?

Yes. Non-residents are subject to the IFI on real estate located in France (directly or indirectly held) if the net value exceeds €1,300,000.

Are financial assets subject to the IFI?

No. The IFI exclusively targets real estate assets. Stocks, bonds, bank accounts, life insurance policies (non-real-estate portion), and other financial instruments are exempt.

Can I deduct my mortgage from my IFI base?

Yes, outstanding mortgage balances on taxable properties are deductible. However, anti-abuse rules may limit deductions for bullet loans, related-party loans, and very large debts.

How is my primary residence treated?

Your primary residence benefits from a 30% abatement on its market value for IFI purposes. A home worth €2,000,000 would be valued at €1,400,000 in your IFI calculation.

What happens if I undervalue my property?

The French tax authorities (Direction Générale des Finances Publiques) can reassess your property values. Penalties of up to 40% of the underpaid tax may apply for deliberate under-reporting, plus interest on late payments.
