I need to talk about something that makes my blood boil every time I review the data: the French property wealth tax, officially called the Impôt sur la Fortune Immobilière (IFI). If you own real estate in France—or you’re a French tax resident with property anywhere in the world—this tax is coming for you. And it’s not cheap.
France abolished its general wealth tax in 2018, replacing it with this narrower version that targets real estate exclusively. Don’t be fooled by the word “narrower.” It still hits hard.
How the IFI Works
This isn’t income tax. This is a tax on what you own. Specifically, your net real estate wealth after debts. Every year. Whether your property generated income or not.
The threshold is €1.3 million ($1.4 million). That sounds high until you realize Paris apartment prices. Or that villa in Provence you bought ten years ago that’s appreciated beyond recognition. Cross that line, and you’re in the system.
Here’s what really matters: the tax is progressive. The rates climb as your net property wealth increases. And unlike some wealth taxes that disappeared quietly over the years, the IFI is alive, well, and strictly enforced by the French tax administration.
The Rate Structure You Need to Know
Let me lay out exactly what you’re facing:
| Net Property Wealth (EUR) | Rate |
|---|---|
| €1,300,000 – €1,800,000 | 0.5% |
| €1,800,000 – €2,500,000 | 0.7% |
| €2,500,000 – €5,000,000 | 1.0% |
| €5,000,000 – €10,000,000 | 1.25% |
| Above €10,000,000 | 1.5% |
Notice the brackets. This is marginal taxation, meaning you pay 0.5% on the portion between €1.3 million and €1.8 million, then 0.7% on the next slice, and so forth. It’s not a flat rate on your total.
What Counts as Property Wealth
Everything real estate. Your primary residence. Investment properties. That country house you barely use. Land. Buildings under construction. Real estate held through certain corporate structures if you control them.
If you’re a French tax resident, they count your worldwide real estate portfolio. Non-residents? Only your French property gets taxed. That’s actually one of the few breaks in this system.
You calculate net wealth by subtracting qualifying debts—mortgages, property-related loans, outstanding renovation bills—from the market value of your properties. Market value as of January 1st each year. The tax administration expects you to be honest, but they cross-reference property sales data. They know what things are worth.
The Math That Hurts
Let me run a scenario. Say you own property worth €3 million ($3.24 million) net after debts.
First €1.3 million: exempt.
€1.3M to €1.8M (€500K slice): €2,500 at 0.5%.
€1.8M to €2.5M (€700K slice): €4,900 at 0.7%.
€2.5M to €3M (€500K slice): €5,000 at 1.0%.
Total: €12,400 ($13,392) annually. Every single year. Whether you rent the properties out or live in them. Whether the market goes up or down.
Now imagine €8 million ($8.64 million) in net property wealth. You’re looking at roughly €57,000 ($61,560) in annual IFI. That’s a new car. Every year. Just for owning real estate.
The Primary Residence Discount
There’s one meaningful relief: your primary residence gets a 30% valuation discount. If you live in a place worth €2 million, it’s assessed at €1.4 million for IFI purposes.
This discount only applies to where you actually live most of the year. Not the vacation home. Not the investment flat. And you better be able to prove residency if they audit you, which they do.
So if your entire property wealth is tied up in your primary home and it’s worth under €1.86 million (which becomes €1.3 million after the discount), you’re under the threshold. Barely.
Who Really Pays This?
French tax residents with significant property holdings. Wealthy foreigners who bought into the Paris or Côte d’Azur markets. People who inherited family estates and are now asset-rich but potentially cash-poor.
That last group is particularly painful to watch. You inherit a château worth €4 million but generate modest income from your actual work. Suddenly you owe €20,000+ annually just to keep the family property. Many are forced to sell. The tax doesn’t care about liquidity.
Strategic Considerations
Some try corporate structures. Holding property through an SCI (société civile immobilière) doesn’t automatically exempt you—if you control the entity and use the property personally, it’s still counted. The rules are designed to pierce through obvious structures.
Others consider moving primary residence offshore while keeping French properties. This converts you to non-resident status, meaning only French real estate gets taxed. But France defines tax residency aggressively: if your economic interests or family remain there, they’ll fight to keep you in the net.
The cleanest exit? Don’t hold French real estate at all if you’re optimizing for tax efficiency. Rent instead. Or hold property in jurisdictions without wealth taxes. I know that’s not always emotionally satisfying, especially with family ties or lifestyle preferences. But the numbers don’t lie.
Compliance and Enforcement
The French tax administration (DGFiP) is sophisticated. They receive notary data on every property transaction. They cross-reference declared values with market comparables. Undervaluing property is risky and usually detected.
You file the IFI declaration alongside your income tax return, typically in May-June. Miss it or file incorrectly, and penalties stack fast: 10% for late payment, 40% for failure to declare, 80% if they deem it intentional.
The declaration form is detailed. Every property. Every debt. Market valuations. If you’re in the system, budget for professional accounting help. This isn’t DIY territory once you’re over the threshold.
The Bigger Picture
France is one of the few OECD countries maintaining a wealth tax in any form. Most others abandoned them—Spain, Germany, Sweden—after realizing they drove capital flight without generating proportional revenue.
The IFI survives partly because it’s politically popular (“tax the rich”) and partly because real estate can’t flee. You can move yourself and your financial assets offshore. You can’t move a building in the 7th arrondissement.
That immobility is precisely why the tax persists. It’s captive revenue.
My Take
If you’re already locked into French property—through residence, family, business—understand this cost is permanent. Factor it into your cash flow planning. It’s as unavoidable as property insurance, just more expensive.
If you’re considering acquiring French real estate and you’re mobile? Think twice. Calculate the IFI liability over 10, 20 years. Add it to notary fees, annual property taxes (taxe foncière), and the wealth tax becomes a significant drag on returns. French real estate has to appreciate meaningfully just to break even on the tax burden.
For those optimizing internationally, France represents exactly the kind of fiscal environment I help clients avoid or exit. The IFI is predictable, transparent, and completely legal. But that doesn’t mean you have to subject yourself to it. Residency and asset location are choices. Make them deliberately.
I track these rules closely because they change, and enforcement evolves. If you need current information beyond what I’ve covered here, the official resource is the DGFiP website. I won’t link directly to forms—they reorganize constantly—but their root domain has the latest guidance.
The bottom line: French property wealth above €1.3 million costs you 0.5% to 1.5% annually in IFI. Forever. Plan accordingly.
