Quick answer: France taxes the net real estate of its residents wherever it sits, so an Italian house enters the IFI base at full market value. Italy charges no wealth tax on that same house. A French buyer therefore acquires a French liability that the property’s own country would never impose, and for many buyers the Italian purchase is what carries them over the €1.3 million threshold for the first time.
For most buyers in this cluster the home country’s tax reacts to what the Italian house earns. For a French buyer it reacts to the fact that the house exists. That difference changes which properties make sense, when to buy, and whether to borrow.
Why does France tax a house that Italy does not?
The impôt sur la fortune immobilière is a tax on net real estate wealth. A French tax resident is assessed on their worldwide property holdings, and the location of the asset is irrelevant to whether it counts. An Italian farmhouse, a Spanish apartment and a Paris flat sit in the same base.
Italy does not have a corresponding tax. It charges IMU, a municipal tax on property computed from the cadastral value and levied at second-home rates on a non-resident’s holiday house, as set out in our IMU guide. That is a property tax, not a wealth tax: it takes no account of the owner’s other assets, their debts, or any threshold.
The result is a genuine asymmetry rather than a double charge in the usual sense. An Italian resident and a French resident owning identical houses in the same comune pay the same IMU. Only the French resident also reports the house in a wealth tax return at home.
Italy’s one wealth-style charge runs the other way. IVIE applies at 1.06% to property held abroad by an Italian resident, which is the mirror image of the French position and catches French owners only if they relocate to Italy, as our IVIE and IVAFE guide explains.
| Charge | Who pays | On what |
|---|---|---|
| Italian IMU | Every second-home owner | Cadastral value of the Italian house |
| French IFI | French residents | Worldwide net real estate above €1.3m |
| Italian IVIE at 1.06% | Italian residents only | Property held outside Italy |
Where exactly does the threshold bite?
The threshold is net taxable real estate above €1.3 million valued on 1 January. Two features of the design make the Italian purchase more consequential than its price suggests.
The first is that the French main residence enters the base after a 30% abatement, and that abatement is specific to it. The Italian house has no equivalent reduction, so €500,000 of Italian property adds €500,000 to the base while €500,000 of French main residence adds €350,000.
The second is what happens on crossing. Once the €1.3 million threshold is passed, the progressive scale applies from €800,000 upward rather than starting at the threshold, so the first euro over the line brings a band of previously untaxed value into charge with it. Buyers who model the Italian purchase as adding a small marginal tax are describing a slope where the system has a step.
-
A couple with a French home at €1.2 million gross is at €840,000 after the abatement, comfortably clear
-
Add an Italian house at €500,000 and the base is €1.34 million, over the line
-
The charge then applies across the scale from €800,000, not on the €40,000 of excess
-
Risk: the crossing is measured annually, so a rising Italian market can put a household over the threshold in a year when nothing was bought
-
The valuation date is fixed, which makes a December sale and a January purchase materially different decisions
-
Where a household is close to the line, the cadastral value guide explains why the Italian fiscal figure cannot be used to keep the declared value down
Does borrowing help, and where is the catch?
IFI is a tax on net wealth, so deductible debt reduces the base. Acquisition debt taken to buy the Italian property is deductible in principle, and this is the main lever available to a French buyer.
The catch is structural. French anti-abuse provisions target arrangements where the debt does not genuinely amortise, and an interest-only loan in fine is treated differently from a conventional amortising mortgage: the deduction is restricted rather than allowed at nominal value throughout the term. Because the exact treatment turns on the loan’s terms and on the taxpayer’s overall position, this is a question to put to a French adviser with the loan documents in hand rather than a rule to apply from a guide.
The Italian side of the same decision is separate and simpler: what an Italian lender will actually advance to a non-resident, at what loan-to-value, is covered in the mortgage guide. A French buyer weighing an Italian mutuo against releasing equity on their French home is comparing two euro loans, so unlike an American or British buyer they are not also taking a currency position.
- Amortising debt behaves predictably in the IFI base; interest-only structures do not
- Debt secured on the French home but used to buy in Italy raises its own questions about which asset the debt attaches to
- A cash purchase maximises the IFI base, which is the opposite of the usual advice about avoiding debt
What does the annual cycle actually look like?
The French obligation is a yearly rhythm rather than a transaction, and the work is small once the pattern is set.
Each 1 January the household values its worldwide real estate. The Italian house is declared at market value with a supportable basis, and the deductible debts are set against it. If the net figure exceeds €1.3 million, the IFI declaration accompanies the income tax return, and the tax is assessed on the scale.
The record-keeping that makes this painless is Italian: a valuation basis kept consistent year to year, the annual IMU receipts, and the mortgage statement showing the outstanding balance on the valuation date. The most common failure is not evasion but reconstruction, where a household crossing the threshold for the first time has to establish values for a property they have owned for years without ever having needed a number.
- Set the valuation method in year one and keep it, since consistency is what makes the figure defensible
- The mortgage balance on 1 January is the deductible figure, not the original loan amount
- Italian letting income is a separate matter under the income convention and does not enter the IFI calculation
One adjacent obligation catches French owners who have handled the property side correctly. An Italian bank account opened to run the house, pay IMU and receive rent is a foreign account, and French residents must declare every foreign account held during the year alongside their return. The declaration is informational rather than a charge, and the penalty for omitting it is per account per year, so a decade of unreported utility banking becomes expensive out of proportion to the sums involved.
What happens on a sale, when Italy has already stopped charging?
The wealth tax is the annual story. The disposal is where the numbers get large, and the two countries’ timetables are so far apart that the Italian rule is close to irrelevant for a French seller.
Italy exempts a private seller’s capital gain once the property has been held for 5 years. France does not exempt a secondary residence for decades. The French charge on a property gain is 19% income tax plus 17.2% social contributions, a headline 36.2%, with a progressive surtax of 2% to 6% where the net gain exceeds €50,000.
Relief arrives by taper rather than by cliff, and the two components run on different clocks. The abatement begins in the 6th year of ownership. For income tax it accumulates at 6% a year through year 21 and completes in year 22. For social contributions it runs far slower, 1.65% a year over the same period, then accelerates to reach full exemption only at 30 years. The income tax horizon has been the subject of active reform proposals, so the exact endpoint is worth checking in the year of sale rather than assumed from a guide.
| Holding period | Italy | France, income tax at 19% | France, social at 17.2% |
|---|---|---|---|
| 3 years | Taxable | Full charge | Full charge |
| 6 years | Exempt | Taper begins | Taper begins, slowly |
| 15 years | Exempt | Substantially reduced | Barely reduced |
| 22 years | Exempt | Exempt | Still charged |
| 30 years | Exempt | Exempt | Exempt |
The practical reading is that a French resident should not treat Italy’s fifth anniversary as a planning milestone at all. It is the milestone for an Italian, a German or a Dutch seller. For a French seller the meaningful dates are two decades out, and the social contributions component, which most buyers overlook because it is not called a tax, outlives the income tax charge by 8 years.
- Insider tip: the French taper counts full years of ownership from the acquisition date in the deed, so a rogito in early January is worth more than one in late December
- Documented improvement costs raise the acquisition base and reduce the eventual gain, which makes Italian renovation invoices worth keeping for decades
- Where the Italian sale is exempt, there is no Italian tax to relieve the French charge, so the whole 36.2% falls unrelieved
Which French buyer scenarios does this change?
The household comfortably below the threshold. IFI is irrelevant and the Italian purchase carries no French wealth cost at all. This profile should read the Italian tax comparison and the rental guide and otherwise proceed as any EU buyer would.
The household near the line. The most consequential profile on the page, because the step effect means a €400,000 Italian purchase can cost far more than €400,000 of marginal tax suggests. The decision framework is to model the household base with and without the Italian asset before making an offer, not after the deed.
The household already well above it. The Italian house adds its value to an existing charge, predictably and at the top of the scale. Here the lever is debt structure rather than whether to buy, and the loan in fine question becomes the main technical issue in the file.
The buyer planning to move to Italy. Everything reverses. French residence ends, IFI stops applying to the worldwide base, and Italian residence brings IVIE at 1.06% on any French property retained. A household that owns a French home and an Italian one can find both taxes applying to the other country’s asset depending on which side of the border they live, which is worth modelling before the move rather than after.
The purchase mechanics themselves carry no French complication and are set out in the step-by-step sequence.
Frequently Asked Questions
Yes, in full. The impôt sur la fortune immobilière reaches the worldwide real estate of a French tax resident, so a house in Puglia sits in the same base as an apartment in Lyon. The threshold is €1.3 million of net taxable property, and the Italian house counts at market value with no abatement, because the 30% reduction applies only to the taxpayer's own main residence in France.
No, and this is the asymmetry worth understanding before buying. Italy levies no wealth tax on Italian property. It charges IMU annually on a second home, which is a municipal property tax on a cadastral base rather than a tax on net wealth. A French resident therefore pays an Italian municipal charge and a French wealth charge on the same house, where an Italian resident pays only the first.
That is the most common way French buyers meet IFI for the first time. The test is net taxable real estate above €1.3 million on 1 January, and a French main residence worth €900,000 after its abatement plus an Italian house at €500,000 clears it. The tax then applies from €800,000 upward on the scale, not merely on the excess above €1.3 million, which is why the crossing is a step rather than a slope.
Deductible debt reduces the net taxable base, and acquisition debt on the Italian property is deductible in principle. The rules around interest-only structures are specific and anti-abuse provisions apply, so a loan in fine does not necessarily reduce the base by its full nominal amount for the whole term. Confirm the treatment of the specific loan with a French adviser before assuming the deduction.
At market value on 1 January each year, declared by the taxpayer. Neither Italian figure helps directly: the cadastral value is a fiscal construct well below market, and the purchase price ages as evidence. French practice accepts a reasoned valuation supported by comparables, and consistency between years matters more than precision in any single one.
Italy taxes it first, at 21% on the first short-let unit or 26% beyond it under the flat regime, or under ordinary IRPEF. The France-Italy income tax convention then governs the French treatment, and French residents declare the foreign income with relief under the convention. The mechanism differs from the wealth tax and the two should not be reasoned about together.
Neither. France is an EU member state, so the reciprocity condition never arises and there is no limit on time spent at the property. The purchase runs identically to an Italian buyer's, and the only French-specific work is the annual declaration once the threshold is in play.
It ends the IFI exposure for that asset, because the base is measured on 1 January and property sold before then is out. It does not end the tax question: the sale proceeds become financial assets, which IFI does not reach, so a sale can move a taxpayer below the threshold entirely. Italy exempts a private seller's gain after 5 years under article 67 TUIR, and the French treatment of the gain follows the convention.
