French buyer buying a French fractional share

The short answer: French residents face French IFI (wealth tax) on their worldwide real-estate value above €1.3M — including any French primary residence, other holiday homes, and fractional shares aggregated together. The fractional share is treated as a real-estate interest through the SCI structure. For a French resident with a primary residence already approaching the IFI threshold, adding a 1/8 fractional share can push the total above €1.3M — making the fractional purchase IFI-triggering even when the share itself is small. The aggregation rule matters more for French residents than non-residents. Specialist French tax advice essential.

The French IFI position for residents vs non-residents

For non-resident buyers (UK, US, others), French IFI applies only to French real estate above €1.3M — see French IFI and fractional ownership. A 1/8 fractional share typically keeps non-resident buyers below the threshold.

For French tax residents, the rule is different: IFI applies to worldwide real estate above €1.3M, with treaty adjustments. The aggregation includes:

• French primary residence (with 30% allowance on the primary-residence value)
• Any other French real estate
• Foreign real estate held directly or through structures
• Fractional shares treated as real-estate interests

The combined worldwide-real-estate value above €1.3M faces IFI at progressive rates from 0.5% to 1.5%.

The fractional share's role in the IFI calculation

A 1/8 fractional share's deemed real-estate value (your proportional share of the underlying property's market value) adds to the French resident's aggregate. For a French resident with an existing €1M primary residence (€700k after the 30% allowance) plus a €400k fractional share value, total aggregate is €1.1M — below the €1.3M threshold. Adding additional French or foreign real estate could push above.

Worked example — French resident impact

Where the fractional structure still helps French residents

Two cases. First, for high-net-worth French residents wanting Mediterranean access without further triggering IFI escalation, the fractional structure adds less to the IFI base than a whole-property purchase would — €400k vs €2-5M. Second, for French residents with existing IFI exposure who'd otherwise buy a whole property abroad and aggregate that into IFI, the fractional structure meaningfully reduces the marginal addition.

Where the fractional structure helps less than buyers might expect

For French residents already over the IFI threshold, any additional French or foreign real estate adds to the IFI base. The fractional structure reduces the magnitude of the addition (€400k vs €2M+) but doesn't eliminate it. Buyers should model the marginal IFI impact specifically.

French income and capital-gains tax position

French residents pay French income tax on worldwide income — including any distributions from a foreign SL / SRL holding a foreign fractional share. Capital gains on disposal of any real-estate interest face French CGT with treaty credits. For a French resident buying a French fractional share, the position is domestic (SCI corporate tax handled by the SCI; resident treatment for individuals). For a French resident buying a foreign fractional share, the cross-border picture adds complexity.

French residency considerations for fractional buyers

Two scenarios where French residency intersects with fractional purchase decisions. First, French residents considering relocation abroad — moving out of French tax residency can substantially change the IFI position; specialist exit-tax advice essential. Second, non-French buyers considering French residency — moving to France introduces IFI on worldwide real estate, so the fractional share's contribution to the aggregate matters more after relocation than before.

What French residents should ask before purchase

Three questions for a French tax adviser. What does this fractional share add to my aggregate IFI base? What is the marginal annual IFI cost of adding this share? Are there structural alternatives (e.g. corporate ownership, specific SCI structures) that reduce the IFI exposure compared with direct ownership?
