French Wealth Tax (IFI) 2026: A Guide for International Property Owners

/in /by

Anyone purchasing or owning property in France should understand the rules surrounding the French Real Estate Wealth Tax, known as the Impôt sur la Fortune Immobilière (IFI). This tax applies to certain property owners whose real estate holdings exceed specific thresholds and can affect both French residents and non-residents.

This guide explains how IFI works in 2026, who may be liable, which assets are included, available exemptions, and how the tax is calculated.

What Is the French Real Estate Wealth Tax (IFI)?

The French Real Estate Wealth Tax is an annual tax imposed on qualifying real estate assets. Introduced in 2018 to replace the former Wealth Tax (ISF), IFI focuses exclusively on real estate wealth rather than overall personal wealth.

The taxable amount is generally based on the net value of property holdings after deducting eligible debts and liabilities. In practice, this means the tax is calculated on the owner’s equity in the property rather than its gross market value.

Who Must Pay IFI?

Non-Residents

Individuals who are not tax residents of France are generally subject to IFI only on real estate assets located in France. The tax becomes applicable when the net value of French property holdings exceeds €1.3 million as of January 1 of the tax year.

French Tax Residents

French tax residents are usually taxed on the value of their worldwide real estate assets. However, certain exemptions and relief measures may apply.

New residents moving to France may benefit from a temporary regime that excludes foreign real estate assets from IFI calculations until December 31 of the fifth year following the year they become French tax residents.

Assets Included in the Tax Base

IFI covers a broad range of real estate holdings, including:

  • Residential properties
  • Apartments and villas
  • Building plots and land
  • Rental properties
  • Certain real estate rights and interests
  • Shares in companies whose value is primarily derived from property

The tax is assessed at the household level, meaning married couples and certain partners submit a joint declaration.

In addition:

  • Property owned by dependent children under 18 must be included.
  • Property held through companies may also be taxable based on the underlying real estate value.
  • Certain professional real estate assets may qualify for exemptions.

Exemptions and Tax Relief

Several exemptions and deductions can significantly reduce the taxable value of property assets.

Main Residence Allowance

A taxpayer’s principal residence benefits from a 30% reduction in its market value when calculating IFI.

For example, a primary home worth €2 million would generally be valued at €1.4 million for IFI purposes before taking eligible debts into account.

Deductible Debts

IFI is calculated on net wealth, meaning qualifying liabilities can reduce the taxable base.

Eligible debts may include:

  • Mortgage loans
  • Property acquisition financing
  • Certain construction and renovation loans
  • Unpaid co-ownership charges
  • Property taxes such as taxe foncière
  • In some circumstances, estimated IFI liabilities

To qualify, debts must:

  • Exist on January 1 of the tax year
  • Be the responsibility of a member of the taxable household
  • Relate directly to taxable property assets

Some limitations apply. For example, family loans are generally excluded, and specific rules affect interest-only loans and liabilities connected to exempt assets.

Professional Property Exemption

Certain real estate used as part of a genuine professional activity may qualify for exemption.

This may apply to properties operated under specific business models, such as para-hotelier activities, provided strict conditions are satisfied. The property must be essential to the professional activity and linked to substantial professional income.

Inherited Property Relief

Certain inherited assets may benefit from favorable treatment depending on the family relationship between the deceased and the beneficiary. Similar advantages may apply to qualifying gifts transferred between family members.

Other Exempt Assets

Additional exemptions may be available for:

  • Forestry and woodland assets
  • Certain agricultural and rural properties
  • Protected heritage properties
  • Specific succession-related situations

Because eligibility depends on individual circumstances, professional tax advice is strongly recommended.

How IFI Is Calculated

The French Real Estate Wealth Tax uses a progressive scale ranging from 0% to 1.5%.

Each tax rate applies only to the portion of taxable wealth falling within the corresponding band.

Example Calculation

If an individual has net taxable real estate wealth of €1.5 million:

  • 0% on the first €800,000
  • 0.5% on the next €500,000 = €2,500
  • 0.7% on the remaining €200,000 = €1,400

Total IFI liability: €3,900

This demonstrates that the tax is not charged on the full value above €1.3 million but rather according to the progressive rate structure.

Special Debt Rules for Large Estates

Additional restrictions apply when:

  • Taxable real estate wealth exceeds €5 million, and
  • Deductible debts exceed 60% of that value.

In these situations, the portion of debt exceeding the 60% threshold is only partially deductible.

For example:

  • Taxable assets: €10 million
  • 60% threshold: €6 million
  • Outstanding qualifying debt: €8 million

The first €6 million remains fully deductible. The remaining €2 million receives only a 50% deduction, resulting in an additional deduction of €1 million instead of €2 million.

Total deductible debt would therefore be €7 million.

Estimating Your Taxable Real Estate Wealth

A simplified approach to estimating taxable property wealth may involve:

Step 1

Determine the property’s market value.

Step 2

Identify all eligible debts connected to the property.

Step 3

Apply any debt deduction restrictions that may apply.

Step 4

Subtract deductible liabilities from the property’s taxable value.

The resulting figure represents the net real estate wealth subject to IFI.

Filing Requirements and Payment Deadlines

IFI is generally declared alongside the annual French income tax return.

Taxpayers must provide details of their taxable real estate holdings and calculate any IFI due according to the applicable rules.

Payment is typically requested later in the year after the declaration has been processed by the French tax authorities.

Key Points to Remember

  • IFI applies to net real estate wealth exceeding €1.3 million.
  • Non-residents are generally taxed only on French property assets.
  • French residents are usually taxed on worldwide real estate holdings.
  • A 30% allowance is available for a qualifying principal residence.
  • Certain debts can reduce the taxable base.
  • Professional property assets may qualify for exemption.
  • Additional debt deduction limitations apply when taxable wealth exceeds €5 million.
  • Annual declarations are required for taxpayers subject to IFI.

Conclusion

The French Real Estate Wealth Tax can have a significant impact on property owners, particularly those with high-value real estate portfolios. Understanding the available exemptions, deduction rules, and filing obligations is essential for effective tax planning and compliance.

Given the complexity of the legislation and the potential financial implications, property owners should seek guidance from a qualified French tax professional to ensure their situation is assessed correctly and all available reliefs are considered.
