Key Takeaways
  • An IR-regime SCI is fiscally transparent: rental income flows through to each partner and is taxed at their personal marginal rate (TMI) plus 17.2% social contributions.
  • An IS-regime SCI can depreciate the property, reducing taxable income, but creates a double taxation trap at exit (corporate tax on gains + flat tax of 30% on dividend distributions).
  • Switching from IR to IS is possible but practically irreversible — the decision locks in your tax structure for the full holding period.
  • For long-term wealth transfer strategies (15+ years), the IR regime benefits from progressive capital gains exemptions unavailable under IS.
  • The right regime depends on three factors: your marginal tax rate, planned holding period, and ultimate goal (income, capitalisation, or succession).
01

The Two Regimes at a Glance

A Société Civile Immobilière (SCI) is a civil real estate company used in France to hold, manage, and transfer property assets. By default it falls under personal income tax (IR): each partner is taxed in proportion to their shareholding on the company’s profits, whether distributed or not. Opting for corporate income tax (IS) is possible at any time, but it carries significant long-term fiscal consequences.

In 2026, with interest rates beginning to ease (the Fed cut rates on 2 September, while the ECB maintains a restrictive stance), real estate portfolios are at an inflection point: balancing immediate rental yield against tax-efficient capitalisation has become a precision exercise. The choice of SCI tax regime is one of the most structurally important — and least understood — decisions for high-net-worth property owners.

The IR-Regime SCI — Fiscal Transparency and Capital Gains Allowances

In an IR-regime SCI, the company is fiscally transparent: it pays no tax as a legal entity. Each partner declares their share of rental income (revenus fonciers) in their personal tax return. This income is stacked on top of their other income and taxed at their applicable TMI (0%, 11%, 30%, 41%, or 45%) plus 17.2% in social contributions.

The principal advantage of the IR regime lies in the treatment of capital gains at disposal. Under the private individual capital gains regime, a progressive allowance applies based on holding period: full exemption from income tax is achieved after 22 years of ownership, and full exemption from social contributions after 30 years. For assets held long-term in a wealth planning context, this mechanism is extremely powerful.

The IR regime also permits, under certain conditions, the offsetting of rental deficits against overall income, up to €10,700 per year. This is particularly attractive for owners undertaking significant renovation works early in the holding period.

“A well-structured real estate portfolio does not optimise tax today — it minimises the total tax burden across the full holding cycle, including at the point of succession.”

The IS-Regime SCI — Depreciation and the Exit Tax Trap

Opting for IS transforms the SCI into an autonomous taxpayer. The company pays corporate tax at 15% on the first €42,500 of profit (for qualifying SMEs) and 25% beyond that threshold. In return, it is entitled to depreciate the property for accounting purposes — something the IR-regime SCI cannot do.

Depreciation allows the annual write-down of a fraction of the property’s value (typically 2%–3% for buildings) against taxable income. On a €500,000 asset, this represents €10,000–€15,000 of tax-deductible expense per year, which can bring taxable profit to zero — or even generate a loss carried forward — even with a satisfactory rental yield.

The IS trap reveals itself at exit. When the property is sold, the capital gain is calculated against the net book value after accumulated depreciation, not the original acquisition cost. This mechanism — known as depreciation recapture — generates an artificially inflated taxable gain subject to IS. Distribution of post-tax profits to partners is then subject to a further 30% flat tax (PFU) or, optionally, to the standard income tax scale. The cumulative double taxation can significantly erode the net gain at disposal.

Comparative Tax Burden: IR vs IS Regime SCI — 15-Year Simulation
Property value €500,000 — Rent €2,000/month — Partner TMI: 41% — Sale after 15 years at €700,000
Rental tax (15 yrs)
IR — €97,000
Rental tax (15 yrs)
IS — €41,000
Capital gains tax
IR — €33,000
Capital gains tax
IS — €108,000
Total tax burden
IR — €130,000

IS-regime SCI

This simulation illustrates a common paradox: the IS-regime SCI produces lower annual taxation thanks to depreciation, but the accumulated tax burden at exit (depreciation recapture + reserve distribution) frequently exceeds the savings accumulated on current income. The result depends heavily on holding period and the partner’s marginal tax rate.

Three Profiles, Three Strategies

The choice between IS and IR cannot be reduced to an arithmetic calculation. It reflects a long-term wealth vision. Here are the three typical profiles we advise at Riviera Wealth Management.

Wealth Preservation Investor

Long-term succession objective, holding period exceeding 15 years, high TMI but modest net rental income after charges. The progressive capital gains exemption is the primary lever.

Recommendation: IR-regime SCI

Active Capitalisation Investor

High rental yield, TMI of 30–41%, 10–12 year horizon, objective of reinvesting profits within the portfolio. Depreciation significantly reduces annual IS, enabling greater compounding.

Recommendation: IS-regime SCI (with careful exit planning)

Business Owner with Holding Structure

An IS-regime SCI can be integrated into a holding company structure: dividends flow up to the holding under the parent-subsidiary regime (95% exemption), virtually eliminating double taxation. This is the scenario where IS wins clearly.

Recommendation: IS-regime SCI + holding company

The Late Conversion Trap

Many taxpayers opt belatedly for IS, attracted by depreciation benefits, without measuring the consequences. Converting an SCI that has held a property for several years to IS triggers immediate taxation of the latent capital gain under cessation of IR activity rules. This “internal exit tax” can reach considerable amounts on properties that have appreciated significantly.

Similarly, reverting from IS to IR requires dissolution and reconstitution of the structure, with the associated legal and fiscal costs. The initial decision should therefore be carefully considered — ideally before any acquisition.

Key Conclusions
  • The IR-regime SCI is preferred for long-term wealth strategies: the holding-period capital gains allowances are a major advantage absent from the IS regime.
  • The IS-regime SCI is effective for active capitalisation investors over short-to-medium terms, particularly when combined with a holding company (parent-subsidiary exemption eliminates double taxation on dividends).
  • IS depreciation generates a real annual saving — but this saving is effectively a deferred tax liability that materialises in full at disposal through depreciation recapture.
  • The transition IR → IS is practically irreversible: structuring correctly at acquisition is the only way to avoid fiscal traps later in the holding period.
  • In 2026, as the rate environment shifts, it is timely to revisit regime appropriateness: falling benchmark rates improve net rental yields, which can materially alter the IS/IR equation.
