The major advantage: Real estate depreciation

Under corporate income tax (IS), the scope of deductible expenses is much broader than under personal income tax (IR). You can deduct:
- Acquisition costs (notary fees, registration fees) from the first SCI tax year.
- Management and accounting fees.

L''investment via a company subject to corporate tax is a capitalization strategy pure.
Limitations and pitfalls: The other side of the coin
While corporate income tax is attractive during the operational phase, it has constraints that a wealth management advisor must anticipate.
Capital gains tax on resale
This is the main drawback. Under corporate income tax, the capital gain is calculated on the difference between the selling price and the Net Book Value (NBV).
- Example: You buy a property for €500,000. You depreciate it by €200,000 over 10 years. The net book value is €300,000. If you resell it for €600,000, your capital gain subject to tax at 25% is €300,000 (€600 - €300).
Under the personal income tax (IR) system, you would have been taxed on €100,000 with allowances based on the holding period. Corporate income tax (IS) is therefore a long-term investment where holding is preferred to quick resale.
The cost of management (accounting balance sheet...)
A company subject to corporate income tax imposes a accrual accounting, A mandatory accounting statement annual and holding general meetings. The use of a chartered accountant is essential, which generates annual costs (approximately €1,500 to €2,500).
Double taxation in the event of cash withdrawals
To use the money for personal gain, you must pay yourself dividends (after tax). These revenues are then subject to the Flat Tax (30 %) or the income tax scale. Corporate tax is ideal for reinvestment, less so for immediate consumption of rental income.

Capital gains on real estate investment companies (SCIs): A point to be aware of
This is where the tax rules become less favorable for IS in the very long term.
Capital gains tax on resale
At IS, the capital gains on real estate SCI are calculated according to the rules for professional capital gains.
- The calculation: Selling price - Net Book Value (NBV).
- The trap: The more you depreciate the asset (which reduces your annual tax), the lower the net book value (NBV), and the higher the taxable capital gain mechanically. Unlike income tax, there is no'capital gains tax exemption for the holding period. Under corporate income tax, you are "married" to the asset. The goal is not to resell to pocket the cash, but to reallocate your assets to reinvest in a new project, or to transfer the shares.
Avoidance strategies
To circumvent this friction at resale, the wealth management experts recommend:
- Selling the shares rather than the building.
- The division of ownership from the outset to purge part of the value.
- Maintaining the asset in the portfolio to generate lifelong income.
Setting up the plan: Key steps
The creation of a structure subject to IS should not be seen as a mere administrative formality, but as laying the foundations of a capitalization vehicle.
