Opting for corporate tax in an SCI: the gains, the costs, and the point of no return

Opting for corporate tax in an SCI: the gains, the costs, and the point of no return

An SCI (société civile immobilière) is taxed under the income-tax regime by default, but it can choose to be taxed as a company under corporate tax (impôt sur les sociétés, IS) - and for some families that choice transforms the economics of holding property. Opting for IS lets the company depreciate the building and shelter its rents at low corporate rates, while deferring the members' personal tax to the moment they take money out. But the option comes at a price that is paid on the way in, while the property is held, and above all on the way out - and, critically, it becomes irrevocable after a few years. This guide sets out the whole decision: how an SCI comes to be taxed as a company, what the option gains you, what it costs while you hold and when you cash out, what the switch itself triggers, and why the decision is close to permanent once the window to reverse it has closed.

The subject matters because the IS option is the most powerful and the most dangerous tax lever an SCI has. Used well - by a family sheltering rental cash flow it means to reinvest - it can save real tax for years. Used without modelling the exit, it can lock a family into a structure that turns a future sale into a heavy bill it cannot avoid, because the option can no longer be undone. For an international family holding French property through an SCI, understanding the gains, the costs and the point of no return before opting is what separates a smart tax choice from an expensive, irreversible mistake.

How an SCI comes to be taxed as a company

An SCI is not, by its legal form, within the scope of corporate tax - but it can enter that scope by two very different routes. The first is choice: an SCI may opt for its subjection to IS (CGI Art. 206, 3.b), and the option can be exercised from the company's constitution or at any point during its life. This is the deliberate route, the one a family takes after weighing the gains and costs set out below. The second route is compulsion: an SCI becomes subject to IS by law where it carries on operations of a commercial character, whether commercial by nature or by determination of the tax law. The most common trigger is furnished letting, which is a commercial activity - the authorities tolerate commercial receipts up to 10% of the company's total receipts, but beyond that tolerance the commercial activity subjects the whole company to corporate tax without any option having been made.

The distinction between the two routes matters because they lead to the same place by different doors, with different consequences for control. A family that opts consciously has weighed the trade-off and chosen it; a family that stumbles into IS through a change in how it uses the property - furnishing an apartment for a better yield, say - arrives at corporate tax by accident, and with it the exit tax and the other consequences, without ever having decided to accept them. The two routes are examined together here because the practical question is the same for both: once an SCI is taxed as a company, whether by choice or by force, what has the family gained, what does it cost, and can it get back out? The answers, especially the last, are what make this the most consequential of an SCI's tax decisions.

The gains: amortisation, low rates, deferral

The attractions of the corporate-tax regime are real and, for the right family, substantial. They come in three connected forms:

• Low corporate rates. A small SCI benefits, under conditions, from the reduced rate of 15% on the fraction of its profit up to €42,500, with the normal rate of 25% above that (CGI Art. 219) - rates that can be well below the marginal income-tax rate that would strike the same profit under the income-tax regime.
• Depreciation of the building. Because the result is computed under business rules, the SCI can deduct or amortise all the financial charges of acquiring the property - notary's fees, registration duties, loan interest - and, above all, depreciate the building itself, an annual charge with no equivalent under the property-income regime that often reduces the taxable rent to little or nothing for years.
• Deferral of the members' tax. The essential feature of the IS regime is that the members are not taxed on the sums not distributed: as long as the profits stay in the company, they bear no charge beyond the corporate tax itself, and the members' personal tax is engaged only when a distribution reaches them.

Taken together, these three gains explain why a family that wants to accumulate rental profit inside the company - to repay a loan, fund works, or reinvest - may find IS compelling. The depreciation shelters the rent, the low rates tax what remains lightly, and the deferral keeps the members' personal income tax at bay until they choose to take money out. During the holding phase, in short, an IS SCI can be markedly more tax-efficient than an income-tax one. The whole difficulty is that this efficiency is, in part, borrowed against the future - a point the costs make plain.

Should your SCI opt for corporate tax?

The answer depends on your rents, your horizon and your plans. Pick what fits - the check explains how the option would work for you.

The costs while you hold and when you cash out

Against the gains sit a set of costs, some running through the holding period and one dominating the exit. The running drawbacks are worth listing plainly:

• a contribution of real property to an IS SCI is taxed at 5%, where the same contribution to an income-tax SCI is registered free;
• the IS SCI is taxed on the rents fallen due in the exercise even if they have not been received;
• a member cannot deduct the interest on a loan taken out to acquire their shares in the IS SCI;
• the free provision of a dwelling to a member has to be reflected by an accounting entry for a notional rent;
• the company's deficits are carried forward without time limit but capped per exercise, and the members cannot impute their share of the loss on their own income;
• the company must keep full commercial accounts, with annual balance sheets and members' current accounts recorded.

Then there is the distribution layer and the exit. A distribution to an individual member is a dividend, taxed in the ordinary case at the single flat levy of 30% (12.8% income tax plus 17.2% social levies), and a very large corporate tax bill attracts, on top, the social contribution on profits of 3.3% on the fraction of the IS exceeding €763,000 for companies with turnover of at least €7,630,000 - a threshold few family SCIs reach, but a reminder that IS is a full corporate regime. The dominant cost, however, appears on sale: the disposal of a building held by an IS SCI is a professional capital gain, and no exemption for the length of ownership applies, so the holding-period taper that private sellers enjoy is unavailable, and because the building has been depreciated, its written-down value swells the taxable gain. The rent sheltered during the holding period is, in effect, recaptured when the property is sold. This is why the option cannot be judged on the annual saving alone - the true comparison is the holding saving against the exit cost, over the whole life the family expects.

The switch itself: immediate taxation, or a deferral

Changing an SCI from income tax to corporate tax is not a costless flick of a switch - the passage is itself a taxable event, unless a deferral is claimed. In principle, the passage to IS entails the immediate taxation of the profits not yet taxed and the capital gains not yet imposed, computed at the moment of the change of tax regime - because the property leaves the private-wealth regime and enters a business balance sheet, the law treats the crossing as a moment of account. Left unmanaged, an SCI switching to IS could therefore face an immediate tax on the latent gain that has built up in its property since acquisition, even though nothing has been sold. Alongside the tax point, the company must produce, within sixty days of the change, the opening balance sheet of the first period taxed under the new regime.

The law softens this with a deferral (sursis d'imposition) that most switching SCIs will want to claim. Where the deferral is opted for, the opening balance sheet shows the property at its original value and its depreciation as though the company had been subject to IS since its creation - so there is no revaluation of the building on entry, and the latent gain is not taxed at the moment of the switch but carried into the corporate regime to be dealt with on a later disposal. The deferral avoids an immediate charge, but it does not make the switch free in the long run: it defers the reckoning to the eventual sale, where the professional-gain rules then apply to the whole gain, depreciation included. So the switch has two possible faces - an immediate tax on the latent gain, or a deferral that postpones it to the exit - and choosing the deferral, filing the opening balance sheet on time, and understanding that the deferral only moves the tax rather than removing it, are the practical steps of a well-managed passage to IS.

What does switching to IS trigger now?

The switch to corporate tax has immediate effects. Pick what concerns you - the check explains what it triggers.

The point of no return

What makes the IS option so grave is that it cannot be undone for long. The option was, for many years, strictly irrevocable; since a reform in 2019 it can be renounced, but only up to the fifth exercise following the one for which it took effect (CGI Art. 239). So a family has a window of a few years in which to change its mind and return to the income-tax regime; once that fifth-year window closes, the option becomes definitive, and the SCI is a corporate taxpayer for the rest of its life. The renunciation must itself be notified within the window; letting it pass, or simply never revisiting the decision, locks the choice in permanently.

The reason this matters so much is the exit tax that the option carries. As long as the family holds the property, the corporate regime may be working in its favour - but the day it sells, the professional-gain rules bite: no holding-period exemption, the depreciation recaptured, and the net proceeds taxed again as a dividend when distributed as a liquidation surplus, with a share sale by individuals falling under the securities-gains regime and the flat levy. If the option is still within its window when a sale comes into view, a family can weigh reverting to income tax to recover the private-gain taper; once the window has closed, that escape is gone, and the exit cost is simply owed. This is the single most important discipline of the whole subject: the moment to model the sale is before the fifth exercise ends, because after it the decision is irreversible and the exit tax unavoidable. An option taken for a holding-period saving, without that modelling, is a bet whose losing side cannot be unwound.

When the option makes sense - and when it does not

Pulling the threads together, the IS option suits a fairly specific profile and misfits another. It tends to make sense where a family is accumulating rental profit to reinvest rather than to draw, where the rents would otherwise be taxed at a high marginal income-tax rate, and where the horizon is medium rather than very long - so that years of sheltered, low-taxed, deferred rent outweigh the exit cost that lies further off. In that profile, the depreciation and the low rates do real work, the deferral keeps the members' tax down, and the family is not relying on a tax-light sale. The deductibility of a manager's remuneration, unavailable under income tax, can add to the case.

It tends not to make sense where the family's plan is to hold the property for the long term and eventually sell or pass it on. There the income-tax regime's private capital-gains taper - full exemption after twenty-two years for income tax and thirty for the social levies - is a decisive exit advantage that IS simply cannot match, and the free contribution of property into an income-tax SCI, against the 5% duty into an IS one, reinforces the point. A family holding to transmit is usually better served by income tax, whatever the annual saving IS would offer, because the corporate regime turns the eventual sale into a heavy, recaptured, twice-taxed gain. The decision, in the end, is not about rates but about time and purpose - and because it becomes irreversible, it should be made once, deliberately, with the exit modelled, rather than drifted into for a short-term saving. That is the discipline this pillar exists to urge.
