The family SCI: a civil holding company in service of wealth

The société civile immobilière (SCI) is a legal structure allowing several people — in this context, members of the same family — to hold one or more real estate assets collectively. Unlike co-ownership (indivision), the default regime when an asset is inherited by multiple heirs, the SCI is built on articles of association that freely organise governance, profit-sharing rules and decision-making procedures. This flexibility is precisely what makes it one of the most powerful instruments in French estate planning.

The mechanics are straightforward: the SCI holds the property, and the associates hold shares in the SCI. Major decisions — selling an asset, accepting a new tenant, undertaking major works — are made at general meetings according to the majority rules set out in the articles. The manager (gérant), typically a parent or the head of the family, handles day-to-day management with powers that the articles define and frame.

In practice, a family SCI is formed with a nominal share capital (often €1,000 to €5,000), while its real economic value corresponds to the net value of the properties it holds. Rental income constitutes the SCI’s revenue, with associates benefiting in proportion to their shareholding — either through distribution or capitalisation, depending on the chosen tax regime.

Income tax or corporate tax: the defining fiscal choice

The first structural decision when creating an SCI is the choice of tax regime. By default, an SCI is subject to income tax (IR): rental income generated by the company flows directly into each associate’s personal tax return, in proportion to their shareholding. The key advantage of this regime is fiscal transparency — and, crucially, the ability to generate a property deficit (déficit foncier) deductible from overall income up to €10,700 per year. This is a valuable lever for higher-rate taxpayers financing renovation works.

Alternatively, an SCI may elect for corporate tax (IS). In this case, it becomes an autonomous fiscal entity: it calculates its taxable profit after deducting all expenses, including depreciation (amortissement) of the property — a deduction unavailable under IR. This depreciation mechanism significantly reduces taxable profit in the early years of ownership, making IS particularly attractive for investors wishing to capitalise rental income rather than distribute it. The 15% IS rate on the first €42,500 of profit is also more favourable than the marginal income tax rate applicable to many associates.

The drawback of the IS regime emerges upon disposal: the capital gain realised by the SCI is computed on net book value (after depreciation), which can generate very substantial taxation at exit. This regime therefore suits real estate portfolios intended to remain within the family over the long term, rather than those earmarked for resale.

The SCI as a succession vehicle: ownership splitting and share gifting

It is in the area of family succession that the SCI reveals its full potential. Rather than transferring a property in kind — with all the constraints of co-ownership and the associated transfer taxes — parents can transfer shares in the SCI. This approach opens two complementary tax optimisation mechanisms: the statutory gift allowance and the discount applicable to unlisted shares.

The legal gift allowance is €100,000 per parent per child, renewable every 15 years. A couple with two children may therefore transfer up to €400,000 of share value every 15 years with zero transfer duty. Over a 30-year horizon — from the SCI’s formation at age 50 to the parents’ passing at 80 — up to €800,000 can be transferred entirely free of gift tax.

The second mechanism is beneficial ownership splitting (démembrement) applied to the shares. Parents retain the usufruct of the shares (and therefore enjoy rental income or the right to occupy the property), while donating the bare ownership (nue-propriété) to their children. The value of the bare ownership, calculated based on the usufructuary’s age using the fiscal scale of Article 669 of the French Tax Code, is significantly below full ownership value. At age 60, bare ownership represents 50% of total value; at 70, 60%. Gift duty and allowances apply to this reduced value — a doubly powerful effect that can dramatically compress transfer costs.

Concrete tax benefits of the SCI in 2026

Beyond succession, the SCI provides several tax advantages in day-to-day portfolio management. Under the IR regime, loan interest is fully deductible from rental income, as are service charges, insurance premiums, property tax (taxe foncière) and management fees. Should rental income turn negative after these deductions, the property deficit is deductible from overall income (excluding loan interest) up to €10,700 per year, with any excess carried forward against rental income for the following ten years.

On the IFI (Impôt sur la Fortune Immobilière — French wealth tax on real estate) front, the SCI itself provides no automatic shield. Shares in an SCI with predominantly real estate assets are subject to IFI at their market value. However, démembrement creates a distribution of the tax burden: once bare ownership has been gifted to children, the parents’ taxable estate for IFI purposes consists solely of the value of the usufruct — not the full property value. IFI optimisation through SCI and démembrement warrants case-by-case analysis with a specialist adviser.

On capital gains, an SCI under IR benefits from the private individual capital gains regime: a progressive allowance based on holding period (6% per year from year 6 to year 21, then 4% in year 22 for income tax; 1.65% per year from year 6 to year 21 for social charges). An SCI held for more than 30 years qualifies for full exemption from both income tax and social charges on any capital gain — a further argument in favour of early formation.
