French buyer buying a French fractional share

The short answer: For French residents, a fractional share is the most IFI-efficient way to own a second home: it adds only your share's value to the IFI base, not the whole property's. IFI (wealth tax) applies to French residents' worldwide real-estate value above €1.3M — primary residence (after a 30% allowance), other holiday homes and fractional shares together. Many residents stay below the threshold even after adding a share; if you're close to it, a French tax adviser can model the exact figure in minutes.

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 share is valued at its own fraction, which often keeps owners well below the IFI threshold (€1.3m of net French property).

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.

If you're already above the threshold

For French residents already over the IFI threshold, any additional real estate adds to the IFI base — and this is where fractional shines: you add €400k, not €2M+, for the same weeks in the same home.

French income and capital-gains tax position

French residents pay French income tax on worldwide income — including any rental income from the share. Capital gains on disposal of any real-estate interest face French CGT with treaty credits for any foreign tax paid. For a French share, the position is purely domestic; for a share abroad, the treaty with that country applies, and our partner walks you through the set-up for your home before you buy.

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, often in your favour. 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 ways to structure my wider holdings that reduce the IFI exposure?
