Property company accounting in Luxembourg

In short. In Luxembourg you hold real estate in two main ways: through a société civile immobilière (SCI), fiscally transparent, whose net rental income is taxed directly in the partners' hands; or through a capital company (SARL, SA, often a SOPARFI), fiscally opaque, which keeps full accounts under the PCN 2020 and pays corporate tax. The choice of structure decides everything: the accounting you keep, the tax you pay and the partners' liability. This guide explains what the firm keeps in each case.

Buying to let, housing your own company in its walls, passing on an estate: the moment a property moves into a structure, one question follows, and it is poorly handled online. How do you keep the accounts of a property company in Luxembourg? The answer depends first on the form you choose, because an SCI and a SARL are neither accounted for nor taxed the same way. Here are the two routes, without jargon, and what each one entails.

SCI or capital company: two structures, two sets of books

The société civile immobilière (SCI) is, according to Guichet.lu, a very common form for managing a property estate: a separate legal structure that owns the buildings and splits their net rental income among its partners. Its purpose is civil, not commercial. Against it, a capital company (SARL, SA, or a SOPARFI holding that carries real estate) is a full commercial company. Both own walls; everything else differs.

That table already settles the main point: you do not pick an SCI or a capital company "for the accounting", but the choice of structure then fully determines the books you keep. Which is why it is worth framing before the purchase, not after.

The Luxembourg SCI: transparent, not a magic tool

This is the most misunderstood point, and it is worth money. A Luxembourg SCI is fiscally transparent: it has no tax personality of its own for profit tax. In practice, the walls do not pay the tax, the partners do, each on their share of net rental income, in their own personal income tax return. The SCI itself keeps "clear and transparent" accounts, per Guichet.lu, with no obligation to publish its accounts or appoint an auditor.

The honest conclusion follows: an SCI is not a tax optimisation device. It creates no tax advantage in itself. It is a tool for holding and organising a property estate, useful to separate the walls from the operating business, arrange a transfer, or own an asset jointly. Those who present it as a tax shortcut are selling an illusion. Its real value lies elsewhere, in structuring.

Holding real estate through a SARL or a SOPARFI

The other route houses the asset in a capital company. Here, the company is opaque: it is taxed in its own name on its result, through corporate income tax (CIT), municipal business tax and net wealth tax, whose calculation we set out in our article on corporate tax in Luxembourg. In return, the partners' liability is limited to their contributions, and the company keeps full commercial accounts, filing its annual accounts with the trade register.

This route makes sense when the real estate sits within an economic activity, when several assets are held, or when a holding sits on top. A SOPARFI can, in fact, carry both participations and real estate; we described its regime and conditions in our guide to setting up a SOPARFI holding in Luxembourg. The choice between transparency and opacity has no universal answer: it depends on your project, your horizon and your personal situation. It is exactly the kind of trade-off to frame up front, with an accounting and tax eye, never on a rule read online.

What the firm actually keeps for a property company

Whatever the structure, the accounting substance of a property company revolves around a few well-defined items:

• Rent collected: tracked asset by asset, tenant by tenant, with due dates and arrears.
• Building expenses: maintenance, insurance, taxes, management fees, and the split between costs recoverable from the tenant and costs borne by the owner.
• The loan and its interest: in a capital company, splitting capital repayment from interest expense directly affects the taxable result.
• Depreciation of the building: in commercial accounts, the building is written down over its useful life, an item that noticeably changes the accounting result.
• Annual expense reconciliations with tenants, and producing the supporting documents.

The difficulty is not the complexity of a single entry, it is the discipline of tracking over time: a property is held for years, and accounts that slip a season are hard to catch up. This is where real-time tracking, in a tool where rent, expenses and loan live together, beats the year-end shoebox. We keep these books in the Odoo we configure for Luxembourg, as described in our article on Luxembourg accounting in Odoo.

Partner liability: the point people forget

One detail of the SCI deserves to be stated plainly, because it carries weight. In a civil company, partners are, per Guichet.lu, jointly and unlimitedly liable towards third parties, each for their share (liability is not joint and several, but it is not limited to contributions either). In other words, if the SCI runs up a debt, the partners' personal assets can be on the line. This is the opposite of a SARL or SA, where liability in principle stops at the capital invested. This factor, often glossed over by those who praise the SCI, belongs in the decision alongside tax.

Who our support suits, and who it does not

Let us be clear. Our fixed fee and real-time tracking are built for an investor or a Luxembourg SME that holds one or a few assets and wants clean, up-to-date accounts with no billing surprises. If you are running a large-scale property development, if your structure is a multi-jurisdiction estate stack with transfer-pricing issues, or if your need is above all sharp wealth and succession advice, a specialist firm will suit you better than we will. We would rather tell you at the first meeting than partway through.

Frequently asked questions

Does an SCI pay tax in Luxembourg?

Not on its profit in its own name: the SCI is fiscally transparent. Net rental income is split among the partners and taxed in each one's hands, in their personal income tax return, according to their share. VAT registration may be required depending on the activity carried out.

Does a société civile immobilière have to keep accounts?

Yes. According to Guichet.lu, a civil company must keep clear and transparent accounts. It is not required to publish its accounts or appoint an auditor, but it must have reliable books, notably to determine each partner's share of the result.

SCI or SARL to hold real estate in Luxembourg?

The SCI is transparent (income taxed in the partners' hands, unlimited liability), the SARL is opaque (corporate tax, liability limited to contributions, full commercial accounts). The right choice depends on your project, your horizon and your personal situation: frame it before buying, with an accounting and tax eye.

Does an SCI let you pay less tax?

No, not in itself. The SCI is a tool for holding and organising an estate, not a tax optimisation device. Its transparency passes income, and tax, straight through to the partners. Its value lies in structuring, not in an automatic tax saving.
