If you're considering moving to France, taxes should be high on your planning checklist — and expat wealth tax France rules are among the most misunderstood aspects of the French fiscal system. Unlike many countries, France imposes a specific wealth tax on real estate holdings, and understanding how it works could save you tens of thousands of euros.
In this comprehensive France expat tax guide, we break down everything you need to know about the Impôt sur la Fortune Immobilière (IFI) for the 2025/2026 tax year — from who owes it, to how it's calculated, to smart strategies for managing your liability.
What Is France's Wealth Tax (IFI)?
France replaced its broad-based wealth tax (Impôt de Solidarité sur la Fortune, or ISF) with a narrower real estate wealth tax called the Impôt sur la Fortune Immobilière (IFI) in January 2018. The key difference? The IFI applies exclusively to real estate assets, not to financial investments, bank accounts, or business holdings.
This is an important distinction for expats. If your wealth is primarily held in stocks, bonds, or retirement accounts, you may have no IFI liability at all — even if your total net worth is substantial. However, if you own significant real property in France (or worldwide, once you become a tax resident), the IFI could apply.
Key Facts at a Glance
- Tax name: Impôt sur la Fortune Immobilière (IFI)
- What it taxes: Net real estate assets
- Threshold: €1,300,000 in net taxable real estate
- Who pays: French tax residents (worldwide real estate) and non-residents (French real estate only)
- Filing deadline: Typically May–June, filed alongside the income tax return
Who Owes Wealth Tax When Moving to France?
Your IFI obligations depend on your tax residency status, which is determined by French domestic law and, where applicable, relevant double taxation agreements.
French Tax Residents
You are generally considered a French tax resident if:
- Your primary home (foyer) is in France
- Your principal place of abode is in France (you spend more than 183 days per year in the country)
- Your main professional activity is exercised in France
- The centre of your economic interests is in France
If any one of these criteria is met, France may claim you as a tax resident. As a resident, your worldwide real estate holdings are subject to the IFI — not just property located in France.
Non-Residents
If you are not a French tax resident but own real estate in France (directly or indirectly), you are only taxable on your French-situated real estate assets. This includes property held through French or foreign legal entities.
The Newcomer Exemption: A Crucial Benefit for Expats
Here's where the moving to France taxes picture gets brighter. France offers a temporary exemption for new tax residents. If you establish your tax residence in France and were not a French tax resident during the five preceding years, you benefit from a five-year exemption on non-French real estate assets for IFI purposes.
During this five-year window, only your French real estate is subject to the IFI. Your properties in the UK, the US, Spain, or anywhere else worldwide are excluded from the taxable base.
Example: Sarah, an American expat, moves to Paris in 2025. She owns a €900,000 apartment in Paris and a €1,200,000 vacation home in Florida. For the first five tax years (2025–2029), only the Paris apartment is counted toward her IFI threshold. Since €900,000 is below the €1,300,000 threshold, she owes no IFI — even though her combined real estate is worth €2,100,000.
This exemption makes France surprisingly attractive for high-net-worth expats, especially those whose significant real estate holdings are located outside France.
IFI Thresholds and Tax Rates for 2025
The IFI uses a progressive rate structure. Although the tax only kicks in when your net taxable real estate exceeds €1,300,000, the actual calculation begins at €800,000 once you cross the threshold.
Here are the IFI rates for the 2025 tax year:
| Net Taxable Real Estate | 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% |
Important nuance: You only owe IFI if your net real estate exceeds €1,300,000, but once you're liable, the calculation applies the scale starting from €800,000. A smoothing mechanism (décote) applies for estates valued between €1,300,000 and approximately €1,400,000 to avoid a cliff-edge tax hit.
Practical Calculation Example
Let's say you're an expat who has been a French tax resident for six years (past the newcomer exemption) and your worldwide net taxable real estate is valued at €2,000,000.
Here's how your IFI would be calculated:
- €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 Counts as Taxable Real Estate Under the IFI?
Understanding what's included — and what's excluded — from the IFI taxable base is critical for expats.
Taxable Assets
- Directly owned residential and commercial property in France (and worldwide for residents, subject to the newcomer exemption)
- Secondary residences and rental properties
- Building land and agricultural land
- Real estate held through legal entities (SCI, SCPI, OPCI, or foreign equivalents) — your share is included proportionally
- Shares in real estate investment funds (to the extent they represent real estate holdings)
- Rights related to real estate (usufruct, lease rights, etc.)
Exempt or Excluded Assets
- Financial investments — stocks, bonds, savings accounts, life insurance (the cash value in €), cryptocurrency
- Professional-use real estate — property used for your trade or business activity (under certain conditions)
- Forestry and rural land — partial exemptions may apply (up to 75% in some cases)
- Your principal residence — benefits from a 30% reduction in market value for IFI purposes
The 30% Principal Residence Discount
This is one of the most valuable IFI benefits. If your home in France is your résidence principale, its value is reduced by 30% before being included in your taxable base.
Example: Your Paris apartment is worth €2,000,000 on the open market. For IFI purposes, it is valued at €1,400,000 (€2,000,000 × 70%).
This discount alone could keep some expats below the €1,300,000 threshold entirely.
Deductions and Liabilities That Reduce Your IFI Bill
The IFI is calculated on your net real estate wealth, meaning you can deduct certain debts and liabilities from the gross value of your real estate.
Deductible Debts
You can generally deduct:
- Mortgage loans directly related to the acquisition, construction, or improvement of taxable real estate
- Property taxes due (taxe foncière) on January 1 of the tax year
- Repair or improvement costs that are not yet paid
- Back-due IFI from prior years
Restrictions on Debt Deductions
French tax law includes several anti-abuse provisions:
- Loans from related parties (family members, controlled companies) may be partially or fully non-deductible
- Bullet loans (prêts in fine) are subject to a straight-line amortization schedule for deduction purposes, regardless of the actual repayment terms
- A cap applies when taxable real estate exceeds €5,000,000: debts exceeding 60% of the value of the real estate may only be deducted at 50% of the excess
The IFI Cap (Plafonnement)
France applies a global cap: your total tax liability (income tax + IFI + social surcharges) cannot exceed 75% of your income for the year. If it does, the IFI is reduced accordingly. This mechanism prevents confiscatory taxation but requires careful documentation.
Common Mistakes Expats Make With French Wealth Tax
Navigating the IFI as an expat comes with several pitfalls. Here are the most common mistakes to avoid:
1. Forgetting to Declare Indirect Real Estate Holdings
Many expats own property through companies, trusts, or foreign structures. In France, the tax authorities will look through these structures and attribute the underlying real estate value to you. Failing to declare these holdings can result in penalties of up to 80% of the tax due in cases of fraudulent omission.
2. Misunderstanding the Newcomer Exemption Period
The five-year exemption on foreign real estate starts from the year you become a French tax resident. If you were previously a French resident and left for five or more years, you may qualify again upon return. However, miscounting the years or failing to document your non-residency can lead to costly disputes.
3. Undervaluing Real Estate
French tax authorities are known for challenging property valuations. You must declare the fair market value (valeur vénale) as of January 1 of each year. Systematic undervaluation will trigger audits and reassessments, potentially with penalties and interest.
4. Overlooking the Interaction With Income Tax
The IFI is filed as part of your annual income tax return, not separately. Expats accustomed to filing wealth declarations independently in other jurisdictions sometimes miss this, leading to late filing penalties.
5. Ignoring Double Taxation Treaty Provisions
France has over 120 double taxation agreements (DTAs). These treaties can affect which country has the right to tax specific real estate and may provide credits or exemptions. For example, the France-US tax treaty includes provisions on real property that could influence your IFI exposure. Always check the applicable DTA for your home country.
How to File and Key Deadlines for 2025
The IFI is declared on your annual income tax return (form 2042-IFI), which is an annex to the standard income tax declaration.
Filing Timeline for 2025
- January 1, 2025: Valuation date — your taxable real estate is assessed as of this date
- April 2025: Online tax filing portal opens
- May–June 2025: Filing deadlines (exact dates vary by département and whether you file online or on paper; online filing is mandatory for most taxpayers)
- September–October 2025: IFI payment notice issued, with payment due shortly after
Steps to File
- Inventory all real estate assets (direct and indirect) as of January 1, 2025
- Determine fair market values for each property
- Apply the 30% principal residence discount if applicable
- Deduct qualifying debts and liabilities
- Complete form 2042-IFI and submit it with your income tax return
- Pay the IFI when the assessment notice is received
If you're new to the French tax system, consider working with a fiscaliste (tax advisor) who specializes in expatriate taxation during your first year.
Planning Strategies for Expats to Minimize IFI
While tax evasion is illegal, legitimate tax planning can significantly reduce your IFI burden.
Leverage the Newcomer Exemption
If you haven't been a French tax resident in the past five years, your first five years offer a window where only French real estate counts. Consider timing major foreign real estate acquisitions (or disposals) around this period.
Restructure Ownership Where Appropriate
Holding real estate through certain French structures (like an SCI subject to corporate tax) may change how the property is valued or taxed for IFI purposes. However, anti-abuse rules are strict — any restructuring must have genuine economic substance.
Reduce Gross Value Through Strategic Borrowing
Since mortgage debt is deductible, financing property acquisitions with qualifying loans can lower your net taxable real estate. Just be aware of the restrictions on related-party loans and bullet loans.
Use the IFI Cap
If your income is modest relative to your real estate wealth, the 75% income cap could reduce your IFI. This is particularly relevant for retirees or those living off capital gains rather than regular income.
Donate to Qualifying Organizations
Donations to eligible public-interest foundations and organizations can be credited against IFI liability, up to 75% of the donation with an annual cap of €50,000. This is one of the few direct IFI reduction mechanisms available.
How Wealth Tax Interacts With French Income Tax
As an expat in France, you'll also face income tax obligations. France's income tax is progressive, with rates ranging from 0% to 45% for 2025, plus social surcharges that can add up to 17.2% on certain types of income.
The interplay between income tax and wealth tax matters because of the 75% cap mechanism mentioned earlier. Your combined tax burden is assessed together, making it essential to plan holistically.

Frequently Asked Questions
Does France tax wealth other than real estate?
No. Since 2018, France's wealth tax (IFI) applies only to real estate assets. Financial assets, business holdings, vehicles, art, and jewelry are excluded.
What happens if my real estate is worth exactly €1,300,000?
You are on the threshold. Technically, IFI applies when net taxable real estate exceeds €1,300,000. At exactly €1,300,000, you are not liable. However, the smoothing mechanism (décote) applies for values just above this threshold.
Do I owe IFI if I own French property but live abroad?
Yes, non-residents are subject to IFI on their French-situated real estate if its net value exceeds the €1,300,000 threshold.
Can my spouse's assets affect my IFI?
Yes. IFI is assessed at the household level (foyer fiscal). If you are married or in a civil partnership (PACS), your combined real estate is assessed together — you cannot file separately for IFI purposes, even if you file separate income tax returns.
Are there penalties for not filing?
Yes. Late filing can incur a 10% surcharge, increasing to 40% after a formal notice, and up to 80% in cases of deliberate fraud. Interest on late payments also applies at 0.20% per month.
