If you own significant real estate assets in France — or anywhere in the world as a French tax resident — understanding France's wealth tax is essential to managing your overall tax burden. Known as the Impôt sur la Fortune Immobilière (IFI), the France wealth tax explained in this guide covers everything you need to know for the 2025/2026 tax year: who must pay, how wealth tax works in France, the applicable rates, key exemptions, filing deadlines, and practical examples to help you estimate your liability.
Whether you're a French resident, a non-resident property owner, or an expat considering a move to France, this comprehensive guide will help you navigate one of Europe's most notable wealth taxes.
What Is France's Wealth Tax (IFI)?
France's current wealth tax is the Impôt sur la Fortune Immobilière (IFI), which translates to "Tax on Real Estate Wealth." It was introduced on January 1, 2018, replacing the broader Impôt de Solidarité sur la Fortune (ISF), which had taxed all forms of wealth — including financial assets, investments, and real estate.
The key distinction is important: the IFI applies exclusively to real estate assets. Financial investments such as stocks, bonds, bank deposits, life insurance (in most cases), and business assets are not subject to the IFI. This reform was designed to encourage investment in the French economy while still taxing concentrated real estate wealth.
Who Must Pay the IFI?
Your liability for the IFI depends on your tax residency status and the net taxable value of your real estate holdings:
- French tax residents: Taxed on their worldwide real estate assets (properties in France and abroad).
- Non-residents: Taxed only on real estate assets located in France (and French real estate held indirectly through companies or trusts).
The IFI applies to individuals, not households, although married couples and civil partners (PACSés) file a joint IFI declaration based on their combined real estate assets.
Key threshold: You are liable for the IFI if your net taxable real estate assets exceed €1,300,000 as of January 1 of the tax year.
IFI Wealth Tax Rates in France for 2025/2026
The wealth tax rates in France follow a progressive scale, much like income tax. However, there is an important nuance: while the taxability threshold is €1,300,000, the taxation starting point is €800,000. This means that once your net real estate wealth exceeds €1.3 million, you are taxed on the portion above €800,000.
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% |
| Above €10,000,000 | 1.50% |
Understanding the Threshold vs. Starting Point
This is one of the most common points of confusion about how wealth tax works in France:
- If your net real estate assets total €1,299,999, you owe nothing.
- If your net real estate assets total €1,300,001, you are taxed starting from €800,000 — not from €1,300,000.
This creates a significant jump in tax liability right at the threshold, which is why careful asset valuation and planning are critical.
Practical Example: Calculating IFI
Let's say you are a French tax resident with net taxable real estate assets valued at €2,800,000 on January 1, 2025.
Here's how your IFI would be calculated:
- €0 – €800,000: 0% = €0
- €800,001 – €1,300,000 (€500,000): 0.50% = €2,500
- €1,300,001 – €2,570,000 (€1,270,000): 0.70% = €8,890
- €2,570,001 – €2,800,000 (€230,000): 1.00% = €2,300
Total IFI due: €13,690

What Assets Are Included (and Excluded) in the IFI?
Understanding which assets count toward your IFI base is crucial to accurate reporting and planning.
Assets Subject to IFI
The following real estate assets are included in your taxable base:
- Directly owned properties: Primary residences, secondary homes, rental properties, vacant land, and commercial real estate.
- Indirectly held real estate: Shares in companies (French or foreign) to the extent they represent underlying real estate assets. For example, if you own shares in a Société Civile Immobilière (SCI) that holds property, the real estate value of those shares is taxable.
- Real estate investment trusts and funds: Including shares in SCPIs (Sociétés Civiles de Placement Immobilier) and OPCIs (Organismes de Placement Collectif Immobilier), proportional to their real estate holdings.
- Real estate rights: Usufruct (usufruit), bare ownership (nue-propriété) in certain cases, and long-term leases.
Assets Excluded from IFI
The following are not subject to the IFI:
- Financial assets: Stocks, bonds, mutual funds (non-real estate), bank accounts, cryptocurrencies.
- Life insurance contracts: Generally excluded, unless they are invested in real estate vehicles (units of unités de compte backed by real estate).
- Business assets: Real estate used in a professional capacity as part of your main business activity (under strict conditions).
- Forestry and rural property: Partial exemptions apply for agricultural land, forests, and shares in forestry groups, typically with a 75% exemption under qualifying conditions.
- Furniture and movable assets: Art, jewelry, vehicles, and other personal property.
The 30% Primary Residence Allowance
One of the most significant IFI benefits 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 allowance applies automatically, but it is only available for your principal residence — not for secondary homes or investment properties.
Deductions: Reducing Your IFI Liability
The IFI allows certain deductions that can lower your taxable base or your final tax bill.
Deductible Debts
You can deduct debts that are directly related to your taxable real estate assets, including:
- Mortgage loans (remaining capital) on taxable properties
- Renovation or construction loans for taxable properties
- Property taxes (taxe foncière) due but not yet paid as of January 1
- Acquisition costs still outstanding
Important limitation: Since 2018, a cap applies on debt deductions for very high-value estates. If your taxable assets exceed €5,000,000, the deductible amount of loans is reduced according to a specific formula. Specifically, only 50% of the debt exceeding €5 million can be deducted.
The Capping Mechanism (Plafonnement)
France applies a tax cap to prevent the combined burden of income tax and wealth tax from becoming confiscatory. Under this rule, the total amount of your IFI plus income tax (including social contributions) cannot exceed 75% of your net income from the previous year.
If the combined taxes exceed this threshold, the IFI is reduced accordingly. However, this mechanism can be complex and is subject to anti-avoidance rules — particularly regarding artificial income reduction strategies.
Charitable Donations
Donations to qualifying organizations (foundations, public interest bodies, certain research institutions) can be credited against your IFI, up to 75% of the donation amount, with a maximum credit of €50,000 per year.
This makes charitable giving one of the most powerful IFI reduction strategies available.
Filing Deadlines and Procedures for 2025
Unlike a separate filing in the past, the IFI declaration is now integrated into your annual income tax return (déclaration de revenus).
Key Steps to File
- Determine your net real estate assets as of January 1, 2025.
- Complete annexes 2042-IFI and, if applicable, 2042-IFI-annexe as part of your online tax filing.
- Declare all taxable real estate, including indirectly held properties through companies.
- Deduct eligible debts and apply the 30% primary residence abatement.
- Submit your declaration online by the applicable deadline.
Filing Deadlines for 2025
The deadlines for filing your 2024 income (and IFI) declaration in 2025 depend on your département of residence:
- Départements 01–19 and non-residents: Typically late May 2025
- Départements 20–54: Early June 2025
- Départements 55–976: Mid-June 2025
Exact dates are announced annually by the Direction Générale des Finances Publiques (DGFiP). Paper filings, where still permitted, usually have an earlier deadline in mid-May.
Payment
The IFI is assessed based on your declaration, and a tax notice (avis d'imposition) is sent separately, typically in August or September. Payment is usually due by September 15 of the filing year, with a later deadline for online payments.
IFI for Non-Residents and Expats
France's wealth tax has important implications for non-residents who own French real estate and for expatriates moving to or from France.
Non-Residents Owning French Property
If you are a non-resident and own real estate located in France — whether directly or through a company — you may be subject to the IFI on those French assets if they exceed the €1.3 million threshold.
This applies even if you:
- Live in a country with no wealth tax
- Own the property through a foreign company or trust
- Are a citizen of a country that does not tax wealth
Tax Treaties and Double Taxation
France has an extensive network of double taxation agreements (DTAs) that may affect your IFI liability. However, most tax treaties do not specifically address wealth tax or only cover income taxes. Some older treaties (such as with Switzerland, prior to its renegotiation) did address wealth tax, but the landscape has shifted significantly since the ISF-to-IFI transition.
Key points:
- Few treaties provide relief specifically for the IFI, as it was introduced after most existing DTAs were negotiated.
- Where a DTA allocates taxing rights on real estate to the country where the property is located (the situs rule), France generally retains the right to tax.
- If you are taxed on the same property by both France and your country of residence, you may be able to claim a foreign tax credit depending on your home country's rules.
Consult a cross-border tax advisor if you hold French real estate as a non-resident.
The 5-Year Exemption for New Residents (Impatriés)
Individuals who become French tax residents for the first time (or after at least five years of non-residence) may benefit from a partial IFI exemption during their first five years of French tax residency. During this period, they are only taxed on French-situs real estate assets, not on their worldwide real estate.
This is a significant benefit for wealthy expatriates relocating to France who own substantial property abroad.
Common Mistakes and Misconceptions
Avoiding these pitfalls can save you money and prevent penalties:
- Confusing IFI with ISF: The old ISF taxed all assets. The IFI only covers real estate. Financial investments are no longer in scope.
- Forgetting indirect real estate holdings: Shares in real estate companies, REITs, or real estate funds are taxable proportionally. Many taxpayers overlook these.
- Overvaluing or undervaluing properties: The taxable value should reflect fair market value on January 1. Undervaluation can lead to reassessments and penalties; overvaluation means overpaying. Getting a professional appraisal for high-value properties is advisable.
- Neglecting the 30% primary residence abatement: This is frequently forgotten, especially by first-time filers.
- Ignoring the capping mechanism: If your income is low relative to your real estate wealth, the 75% cap could significantly reduce your IFI.
- Missing the filing deadline: Late filing can result in penalties of 10% of the tax due, plus interest.
