Business permit, commission subject to 17% VAT, client money to ring-fence, one-off sales and recurring letting management: what sets the accounting of a Luxembourg estate agency apart.

In short. A real estate agency is not a shop like any other. Working as an estate agent in Luxembourg requires a business permit, a recognised qualification and professional liability insurance. On the accounting side, your turnover is your commissions, and they are subject to VAT at the standard rate of 17 %, even when the sale or letting you brokered is itself exempt. Money you hold on a client's behalf must never mix with your own income. At Advena, this accounting is kept in real time, on a fixed fee, from 325 € per month.

You sell and let property on behalf of others, and an agency's accounting is nothing like a shop's till. No stock, a turnover made of commissions that are sometimes large but irregular, money passing through without belonging to you, and a regulated activity from the very first mandate. Here is what really sets an estate agent's accounting apart in Luxembourg, and the points where a mistake costs money.

A regulated activity from day one

Before any talk of accounting comes the right to practise. In Luxembourg, an estate agent, the person who acts as intermediary in the sale, exchange, letting or transfer of property, must hold a business permit (autorisation d'établissement). According to Guichet.lu, obtaining it requires three things: professional integrity, a recognised qualification and professional liability insurance. The qualification is gained either through the "Estate agent" training run by the House of Training, or through three years of experience in a management role in a licensed Luxembourg agency. The framework is the amended Law of 2 September 2011 on the right of establishment.

Two useful nuances. The permit assumes a fixed place of business in the Grand Duchy, not a mere mailbox. And neighbouring trades fall under separate permits: the property manager and building trustee (syndic), the property introducer (apporteur d'affaires) or the developer are not the same activity as the estate agent, even if one agency sometimes combines several. Each hat has its own obligations, and that shows in the accounts.

The commission, your turnover, and its VAT

This is the most misunderstood point of the trade, and it is worth money. Your income is not the price of the property, it is your commission. And that commission is an intermediation service, subject to VAT at the standard rate of 17 %. It does not matter that the underlying transaction is exempt: the letting of a home is VAT-exempt, the sale of an existing building falls under registration duties, but your agency fee stays taxable. So you charge VAT on your commissions and recover the VAT on your expenses.

This distinction throws people because they assume it mirrors the property's regime. It does not. The VAT regime of the building and that of your intermediation are two separate things. To place the first, our article on VAT and property letting in Luxembourg covers the exemption and the option to tax, and our guide to VAT rates in Luxembourg in 2026 sets the 17 % standard rate in context. The second, your commission, follows its own logic as a service provider.

Then there is timing. A commission is only income once it is earned, generally when the sale is completed, often at the signing of the notarial deed, depending on the terms of your mandate. A signed preliminary agreement is not yet a booked sale. Recognising too early a commission that can still fall through builds a profit that does not exist and VAT payable on thin air.

Unsure about the VAT on your commissions or when to recognise them? We set up your configuration, on a fixed fee.

Talk about your agency

The money that is not yours

An agency often handles funds that do not belong to it: a deposit, a rental guarantee, a sum entrusted while a signature is pending. This money is not income. Booking it as turnover artificially inflates your profit, distorts your VAT and, the day you must hand it back, leaves you overdrawn on your own accounts. The rule is simple to state and demanding to keep: funds held on behalf of third parties live on separate accounts and are tracked as third-party accounts, never mixed with the agency's cash. In many files the escrow actually goes through the notary, which clarifies matters; but as soon as a flow passes through you, it must be traceable and ring-fenced. It is a point of rigour that inspections look at, and that your clients' trust depends on.

Two rhythms: the one-off sale and the recurring management

An agency rarely lives off a single flow. Sale commissions land in bursts, large and unpredictable: three months with nothing, then two deals in the same week. Letting management and property administration, by contrast, generate regular fees, smaller but predictable. These two rhythms are not steered the same way. On sales, the danger is a saw-tooth cash position and the tax on a good year falling during a bad one; provisioning is vital. On management, the challenge is the clean tracking of many mandates and small amounts. Accounting kept continuously, clearly separating the two sources of income, tells you at any moment where your margin really comes from, which a year-end discovered in the spring never allows.

The expenses that make an agency what it is

An agency's profitability rides as much on its costs as on its commissions, and those costs have a colour all their own. Visibility first: subscriptions to listing portals, online advertising, photos and videos, home staging, signboards. Mobility next, because the trade happens in the field: vehicle, fuel, travel. Introducer fees last, when a deal comes from a third party. Each of these is deductible and, for most, opens the right to recover VAT if it is properly documented and tied to the activity. The classic mistake is mixing private and professional, especially on the vehicle and the phone. The baseline obligations that apply to any company, whatever the sector, are set out in our article on the accounting obligations of a Luxembourg SME.

PCN 2020, annual accounts and tax

If you operate through a company, your agency keeps double-entry accounts under the standard chart of accounts, the PCN 2020, draws up its annual accounts and files them with the trade register. It is liable for corporate income tax, municipal business tax and net wealth tax, whose calculation is detailed in our article on corporate tax in Luxembourg. If your agency is starting out, the accounting decisions of the first twelve months weigh for a long time; we framed them in our guide on accounting in year one. And if you also hold property in your own right, alongside the agency activity, that is a separate accounting matter, covered in our article on property company accounting in Luxembourg.

How we keep an agency's accounts

We keep your accounting in the Odoo we configure for your activity: the 17 % VAT on your commissions, the split between sale fees and management fees, and the tracking of sums held on behalf of third parties. Your receipts, your invoices and your expenses live in one place, so your real margin and your VAT read in real time, not the following spring. For an agency whose income arrives in bursts, this continuous view changes one decisive thing: you provision the tax on a good year while the money is there, instead of discovering it once it has been spent. It all sits inside a fee announced in advance, from 325 € per month, all in and with no hourly billing: a question put to your account manager does not come as an extra. The market's billing models are broken down in our article on what an accounting firm costs in Luxembourg.

Who this model is not for

Let us be straight about it. Our fixed fee and our real-time approach suit the Luxembourg agency that wants to steer its margin and stay tidy on its third-party funds and its VAT. If you only want to drop off a bundle once a year at rock-bottom price, without ever looking at your figures between year-ends, our continuous tracking will not serve you. And if your activity spills into complex wealth structuring or large-scale property development, that goes beyond current bookkeeping: we inform you and point you to the right specialist, without ever claiming a regulated title we do not hold.

Frequently asked questions

Do you need a permit to open a real estate agency in Luxembourg?

Yes. The estate agent must hold a business permit, which requires professional integrity, a recognised qualification (dedicated training or three years of management experience in a licensed agency) and professional liability insurance, under the Law of 2 September 2011. A fixed place of business in Luxembourg is required, not a mere registered address.

Is a real estate agency's commission subject to VAT?

Yes, at the standard rate of 17 %. The commission is an intermediation service, taxable as such, regardless of the property's regime. Whether the letting is exempt or the sale falls under registration duties changes nothing: your agency fee remains subject to VAT, and you recover the VAT on your expenses.

How do you account for deposits and guarantees received from clients?

These sums are not agency income. They are tracked as third-party accounts, on separate accounts, never mixed with your cash or booked as turnover. In many files the escrow goes through the notary. The traceability of these funds is looked at in an inspection.

When does a sale commission become accounting income?

When it is earned, generally on completion of the sale, often at the signing of the notarial deed, depending on the mandate terms. A signed preliminary agreement is not enough to recognise the commission as definitive income: booking it too early distorts profit and VAT.

Which expenses can a real estate agency deduct?

Listing portals, advertising, photos and videos, home staging, signboards, the vehicle and travel, as well as introducer fees, are deductible and mostly open the right to recover VAT if documented and tied to the activity. The rule is not to mix private and professional expenses.
