SCI Under Corporate Tax (IS) vs. Income Tax (IR): Which Tax Regime to Choose?

The Fundamental Choice: Tax Transparency or Opacity

The tax regime of an SCI (Societe Civile Immobiliere) is the single most structural decision you will make over the entire life of the company. This choice, which is largely irreversible, determines how rental income will be taxed, how capital gains will be treated on resale, what accounting obligations will apply, and what the optimal long-term wealth strategy will be.

Two radically different approaches exist. The SCI under IR (income tax), the default regime, operates on the principle of fiscal transparency. The company itself owes no tax: profits and losses flow directly through to the shareholders, who report them on their own personal tax returns. The SCI is fiscally "transparent," as if the shareholders owned the property directly.

The SCI under IS (corporate tax), an optional regime, operates on the principle of fiscal opacity. The company is a separate tax entity: it calculates its own taxable profit, pays its own tax, and only distributes to shareholders whatever it decides to pay out as dividends. Shareholders are only taxed on amounts they actually receive.

This distinction between transparency and opacity drives all the tax consequences detailed below.

Rental Income Taxation: Two Radically Different Mechanisms

Under the SCI at IR: Progressive Income Tax Scale

Rental income from an SCI under IR is classified as property income (revenus fonciers) for unfurnished lettings. Each shareholder declares their proportional share of the property income on their personal tax return, based on their stake in the SCI.

The property income is calculated as follows:

Gross property income (rent collected) Minus: deductible expenses (maintenance and repair work, loan interest, insurance premiums, property tax, management fees, manager's fees) = Net property income

This net income is subject to two levies:

• The progressive income tax scale at your marginal tax rate (TMI)
• Social contributions of 17.2%

The overall tax burden therefore depends on your marginal tax bracket:

For an investor in the 30% bracket, nearly half of net rental income goes to taxes. For those at 41% or 45%, it is more than half.

Under the SCI at IS: Corporate Tax

The SCI under IS calculates its own taxable result according to commercial accounting rules. The fundamental difference is the ability to depreciate the property (excluding the land portion), which considerably reduces the taxable profit.

The IS taxable result is calculated as follows:

Revenue (rent, indemnities) Minus: deductible expenses (same as under IR plus accounting fees) Minus: depreciation of the property (broken down by component) = Taxable result

This result is subject to corporate tax at the following rates:

• 15% on the first 42,500 euros of profit (reduced SME rate)
• 25% on the remainder

Let's take a concrete example. A property generates 10,800 euros of annual rent and 4,000 euros of deductible expenses. The annual depreciation is 5,600 euros.

The difference is striking: depreciation combined with the reduced IS rate divides the tax bill by more than 15 in this example.

Treatment of Losses: Advantage to IR

Property Loss (Deficit Foncier) Under IR

One of the key strengths of the SCI under IR is the property loss mechanism. When deductible expenses (excluding loan interest) exceed property income, the loss can be offset against the shareholder's overall income up to a limit of 10,700 euros per year per household.

This offset is particularly advantageous at the start of an investment, when major renovation works generate a deficit. A shareholder at TMI 30% who offsets 10,700 euros of property loss saves 3,210 euros in income tax immediately, plus 1,840 euros in social contributions -- roughly 5,050 euros in tax savings.

Any excess loss (above 10,700 euros, or the portion corresponding to loan interest) can be carried forward against property income for the following 10 years.

Loss Under IS

In an SCI under IS, losses have no impact on the shareholders' personal income. They can be carried forward indefinitely against future profits of the SCI. It is an internal mechanism: losses reduce corporate tax in subsequent profitable years but provide no direct tax benefit to the shareholders personally.

Filing and Accounting Obligations

SCI Under IR: Lighter Requirements

The SCI under IR must file a form 2072 with the tax authorities each year. This return summarises the SCI's income and expenses and allocates the result among the shareholders. Each shareholder then reports their share on their form 2044 (property income).

The SCI under IR has no formal accounting obligation: no balance sheet, no income statement, no notes. It is nonetheless recommended to keep cash-basis accounts (receipts and disbursements) to facilitate the 2072 filing and justify expenses in case of an audit.

Estimated annual cost: 200 to 500 euros if you engage an accountant for the 2072 return.

SCI Under IS: Full Commercial Accounting

The SCI under IS is subject to the same accounting obligations as a commercial company. It must prepare:

• A balance sheet (assets/liabilities)
• An income statement
• Notes to the accounts
• A tax return (form 2065) with supporting schedules

This accounting must comply with the Plan Comptable General and apply depreciation by component. Engaging an expert-comptable (chartered accountant) is virtually essential, at an annual cost of 800 to 2,000 euros depending on complexity.

The SCI under IS must also hold formal general meetings, draft minutes, and, if it distributes dividends, carry out withholding tax obligations and related filings.

Capital Gains on Resale: The IS Trap

Capital Gain Under IR: Individual Regime

In an SCI under IR, the capital gain on the sale of a property falls under the individual property capital gains regime. This regime is very favourable thanks to holding-period allowances:

Allowances for income tax (19%):

• 0% for the first 5 years
• 6% per year from the 6th to the 21st year (i.e. 96% cumulative)
• 4% in the 22nd year (full income tax exemption)

Allowances for social contributions (17.2%):

• 0% for the first 5 years
• 1.65% per year from the 6th to the 21st year
• 1.80% in the 22nd year
• 9% per year from the 23rd to the 30th year (full social contributions exemption)

Example: Property purchased for 200,000 euros, sold for 280,000 euros after 20 years of ownership.

Gross capital gain = 80,000 euros. Income tax allowance = 90% (6% x 15 years = 90%). Social contributions allowance = 24.75% (1.65% x 15 years). Taxable gain for IT = 8,000 euros. Taxable gain for SC = 60,200 euros. Total tax = 8,000 x 19% + 60,200 x 17.2% = 1,520 + 10,354 = 11,874 euros.

Capital Gain Under IS: Corporate Regime

In an SCI under IS, the capital gain is calculated on the difference between the sale price and the net book value (VNC) of the property, i.e. the purchase price minus accumulated depreciation. This is the major pitfall of the IS regime.

Example with the same property: Property purchased for 200,000 euros (of which 40,000 is land). Accumulated depreciation over 20 years = approximately 112,000 euros. Net book value = 200,000 - 112,000 = 88,000 euros. Sale price = 280,000 euros. Capital gain = 280,000 - 88,000 = 192,000 euros (vs. 80,000 under IR!).

Corporate tax on the gain = 42,500 x 15% + 149,500 x 25% = 6,375 + 37,375 = 43,750 euros. After corporate tax, 192,000 - 43,750 = 148,250 euros remains for distribution. Flat tax (PFU) of 30% on dividends = 44,475 euros. Total tax on the capital gain = 88,225 euros (vs. 11,874 euros under IR).

Full Worked Example: Comparison Over 10 and 20 Years

Let us take a concrete case to compare the two regimes over time. Assumptions: property purchased for 200,000 euros plus 20,000 euros of works, monthly rent of 900 euros (indexed at 2% per year), annual expenses of 2,400 euros, loan of 180,000 euros over 20 years at 3.5%, TMI 30%, property appreciation of 1.5% per year.

Comparison at 10 Years

At 10 years, the tax saving on rent under IS is offset by the higher structural costs and, above all, by the much heavier tax on capital gains under IS. The SCI under IR comes out ahead.

Comparison at 20 Years

At 20 years, the SCI under IS takes a slight lead: the cumulative tax savings on rent (45,500 euros) exceed the capital gains tax differential (55,000 euros) and the additional structural costs (20,000 euros). But the gap is narrow and sensitive to the underlying assumptions.

Decision Tree: Which Regime to Choose?

Here is a practical guide to help orient your choice:

Choose the SCI under IR if:

• Your marginal tax rate is low or moderate (0%, 11%, 30%)
• You anticipate selling the property in the medium or long term
• You want to benefit from holding-period capital gains allowances
• You are carrying out significant works and want to use the property loss mechanism
• You prefer simplicity in management and accounting
• Your primary goal is estate planning (capital gains exempt after 22/30 years)

Choose the SCI under IS if:

• Your marginal tax rate is high (41% or 45%)
• You want to reinvest rental income within the company without distributing it
• You do not plan to sell the property (very long holding period or transfer of shares)
• You are investing in properties with a high rental yield
• You want to reinvest profits into new properties
• You accept the higher accounting costs and heavier administrative requirements

Key Considerations Before Making Your Decision

The Irreversibility of the IS Option

The election for IS is irrevocable (except within the first five years, under very restrictive conditions introduced by the 2019 Finance Act). Once the election is made, there is no going back to IR. This irreversibility requires you to project the consequences over the very long term, taking into account potential changes in circumstances (reduction in marginal tax rate, death of a shareholder, plan to sell, legislative changes).

Double Taxation of Dividends

In an SCI under IS, profits distributed to shareholders are subject to the flat tax (PFU) of 30% (12.8% income tax + 17.2% social contributions) or, at the shareholder's election, the progressive income tax scale (with a 40% allowance) plus social contributions. This is double taxation: corporate tax at the company level, then flat tax at the shareholder level. The overall tax rate on distributed profits is therefore:

• 15% corporate tax + 30% flat tax on the remainder = approximately 40.5% at the reduced rate
• 25% corporate tax + 30% flat tax on the remainder = approximately 47.5% at the standard rate

This overall rate is comparable to, or even higher than, the IR tax burden for lower marginal brackets. This is why the SCI under IS is only advantageous when shareholders do not distribute profits (capitalisation within the company) or when their marginal tax rate is very high.

Impact on Bank Financing

Banks analyse applications differently depending on the tax regime. An SCI under IS with a result reduced by depreciation may show a low accounting profit, which can complicate obtaining additional financing. In an SCI under IR, property income flows through to the shareholders' personal income, which strengthens their individual borrowing capacity.

Conclusion: A Decision That Warrants Professional Guidance

The choice between SCI under IR and SCI under IS has no universal answer. It depends on your marginal tax rate, your intended holding period, your strategy for distributing or capitalising profits, your plans for resale, and your estate planning objectives. The performance gap between the two regimes can reach tens of thousands of euros over 20 years, in either direction.
