French IFI for Americans: What Changes After Your First Five Years?
By Thomas Dubanchet | Bespoke – Tailored Tax Solutions
Your French real estate wealth tax can increase without your buying another property.
For many Americans, the explanation is the end of the temporary relief for new French residents. A U.S. home or rental portfolio that was outside the French IFI base can enter it when the relief expires. Nothing needs to be sold, inherited or transferred.
This makes the final protected year a planning year. The relevant question is what your taxable real estate position will look like on the next January 1, and whether you want to change anything before then.
What the five-year relief actually protects
French residents are generally within IFI on taxable real estate assets in France and abroad. Article 964 provides a temporary restriction to French real estate exposure for individuals who were not French tax residents during the five calendar years preceding their arrival year. It lasts through December 31 of the fifth year following that arrival year, while French residence continues. French Tax Code, Article 964.
That is a geographical limitation. Your French property can still be taxable during the protected period.
Nor is the arrival anniversary the relevant expiry date. For someone who became French resident during 2021 and qualifies for the relief, the final protected year is 2026. On the law in force when this article was prepared, worldwide taxable real estate enters the analysis on January 1, 2027.
The January date matters because IFI takes an annual snapshot. A decision made after that snapshot normally changes the following year's position, rather than rewriting the position already established.
The treaty provides a second route for some Americans
Article 23(6) of the France–U.S. treaty also protects foreign assets during the five calendar years following the year of French residence for a U.S. citizen who does not also hold French nationality. It contains a separate rule for a return after at least three years of nonresidence. France–U.S. treaty, Article 23(6).
The domestic and treaty provisions should be checked separately. A dual French–U.S. citizen may qualify under domestic law even though this particular treaty provision excludes dual nationals. Someone returning to France may need the treaty route assessed against their previous residence history.
“Americans get five years” leaves out the facts needed to apply the right rule. Record which provision supports your position and its expiry date.
Start with a complete real estate inventory
IFI concerns real estate exposure, including relevant indirect ownership. A company name on the title does not by itself remove the underlying property from the calculation. Conversely, owning shares in a business does not mean every asset inside it is automatically taxable real estate; statutory exclusions and the use of the property matter. DGFiP: 2026 IFI guidance.
Prepare the inventory before asking for valuations. Include directly owned homes, rental properties, relevant interests in property-owning entities and any arrangements whose ownership needs clarification. For each, identify your interest, its location, its use and the associated borrowing.
The inventory should distinguish an estimate of market value from the French taxable value. A U.S. property tax assessment, an online estimate and an agent's current market appraisal can answer different questions. Where the number is material, obtain evidence appropriate to the January 1 valuation.
If a trust is involved, identify who is treated as owning the property for IFI purposes before adding its assets to anyone's schedule. A list of beneficiaries is not, by itself, an allocation of the tax base.
A French home below the threshold can still be part of a taxable household
IFI applies when the household's net taxable real estate wealth exceeds €1.3 million. Married couples are generally assessed together, subject to statutory exceptions. The threshold is therefore not normally available separately to each spouse. French Tax Code, Article 964.
A directly owned principal residence benefits from a 30% valuation allowance. Do not automatically apply that allowance to an ordinary SCI interest merely because the company owns the home you occupy. The ownership structure needs to be checked. French Tax Code, Article 973.
Consider a fictional couple who qualified for the newcomer relief on arrival in 2021. They directly own their French principal residence, worth €1.5 million, and U.S. rental property worth €1.7 million. Assume the values remain unchanged, there is no debt, and the rental property becomes fully taxable when the relief ends.
| Position | During the protected period | After the relief expires |
|---|---|---|
| French home after the 30% allowance | €1,050,000 | €1,050,000 |
| U.S. rental property included in IFI | €0 | €1,700,000 |
| Net taxable real estate | €1,050,000 | €2,750,000 |
| IFI under the current scale, before any cap, reduction or credit | €0 | €13,190 |
The €13,190 is calculated under the current progressive scale: €2,500 on the band from €800,000 to €1.3 million, €8,890 on the next band to €2.57 million, and €1,800 on the remaining €180,000. Once the entry threshold is crossed, the calculation starts at €800,000. This is an illustration under current law, not a forecast of future legislation. French Tax Code, Article 977.
The couple has acquired nothing new. The change is the expiry of a relief that previously excluded an existing asset.
Review the borrowing, including what it financed
Debt can reduce IFI exposure, but an outstanding loan balance is not automatically deductible. The debt must satisfy the statutory conditions, including its connection with taxable assets and qualifying expenditure. Interest-only loans with repayment at maturity, family lending and certain large debt positions have specific restrictions. French Tax Code, Article 974.
This matters when a property has been refinanced several times. The current lender's statement tells you what is owed. It may not establish what every advance financed. Separate the acquisition borrowing from later cash withdrawals and keep the documentation linking each amount to its use.
It also matters when considering a new mortgage. Compare the prospective IFI saving with interest, arrangement costs, currency exposure and the consequences for your investment portfolio. Borrowing can preserve liquidity and serve a sensible financing plan. A tax saving alone does not establish that the loan improves your overall position.
Use the final protected year to make a real decision
Once the inventory and calculation are complete, the choices become clearer. You may decide to retain the U.S. property and budget for IFI. You may already have commercial reasons to sell. You may prefer to reduce debt, even though that increases taxable equity, because certainty matters more to you than the tax saving.
The right comparison includes rental income, management costs, expected capital expenditure, sale taxes, financing and the role of the property in your life. A home kept for family visits has a use that will not appear in a spreadsheet. It still deserves an explicit annual cost.
Selling also creates a separate capital gains question. Do not assume that reducing future IFI necessarily produces a better result once the sale taxes in both countries are included. Nor should a proposed transfer to a company or family member be judged solely by the resulting IFI figure.
By the autumn of the last protected year, aim to have a supported expiry date, a current asset and debt schedule, and a comparison of the options you would actually consider. Then there is time to implement a decision before January 1.
The purpose of the review is to decide whether keeping your existing property portfolio remains worth its full cost. At Bespoke, we assess that question alongside your income tax, financing and estate plan, so that one annual tax does not dictate the whole decision.
