Registration duties in Brussels: what you need to know in 2026

Registration duties in Brussels: rates, reductions and practical advice

Registration duties in Brussels stand at 12.5% of the purchase price for most property transactions in 2026. This is a substantial tax burden that both buyers and sellers need to plan for. Understanding how the system works helps you prepare your file properly and avoid unpleasant surprises on the day of signing.

The base rate: 12.5% in Brussels

In the Brussels-Capital Region, the standard rate for registration duties is set at 12.5% of the market value of the property. This rate applies to the vast majority of property purchases, whether a house, an apartment or a building plot.

This percentage is calculated on the higher of two figures: the purchase price stated in the deed and the market value estimated by the tax authority. If the authority considers the declared price to be below market value, it may reassess and issue a correction.

By way of comparison, Flanders has applied a rate of 2% to the purchase of your only own home since 2025, and Wallonia a rate of 3% to your own home, with 12.5% as its standard rate. Brussels has no reduced rate but exempts part of the price instead, which makes it all the more important to understand how that exemption works.

The Brussels abatement: up to €25,000 in savings

The Brussels Region provides a reduction on the taxable base for buyers purchasing a primary residence. In practice, the first €200,000 of the property's value is exempt from registration duties, provided certain conditions are met and the purchase price, or the market value if that is higher, is no more than €600,000.

This reduction represents a saving of €25,000 (12.5% of €200,000). It is not phased out gradually, but it disappears completely above the limit: if the property costs more than €600,000, you pay 12.5% on the full amount. For a home priced at €400,000, the abatement brings the registration duties down from €50,000 to €25,000.

To benefit from this reduction, the buyer must:

• Buy the whole property in full ownership as a natural person.
• Not own the whole of another home in full ownership, in Belgium or abroad, on the date of the preliminary sale agreement.
• Register at the property's address in the population register within three years of purchase.
• Keep their primary residence in the acquired property for at least five uninterrupted years. Anyone who moves out earlier repays part of the benefit, in proportion to the years remaining.

It is strongly advisable to verify these conditions with a notary before signing any preliminary sale agreement.

Preferential arrangements for small inheritances and transfers between relatives

Brussels also provides reduced rates in certain specific situations. For example, in the case of a property gift between parents and children, gift duties apply instead of registration duties, according to a progressive scale that may prove more advantageous depending on the value of the property.

For transactions between close relatives in the direct line, it is worth consulting a professional to compare the various options available. A good adviser will tell you whether a standard sale or another form of transfer is more advantageous from a tax perspective.

On the seller's side, registration duties are in principle borne by the buyer. That said, market realities mean these costs directly affect the purchasing power of prospective buyers and, consequently, the price you can realistically expect to achieve for your property. Working with an experienced local estate agent helps you position your property at a realistic price. You can compare licensed estate agents in Brussels via IMV to find the one who knows your neighbourhood best.

VAT or registration duties: when one replaces the other

For new-build properties or properties that have undergone major renovation, VAT at 21% applies instead of registration duties. This regime applies primarily to property developers and private individuals selling a new-build property within two years of its first occupation.

In this case, registration duties are only due on the land portion. The construction element is subject to VAT. This mechanism is particularly relevant for development projects in Brussels, where a significant number of new apartments come onto the market each year.

If you are selling a new-build property, it is advisable to check with your notary which of the two regimes applies to your situation. An error in the classification of the property can lead to significant tax complications.

The impact of registration duties on selling your property

As a seller, you do not pay registration duties directly. But these costs weigh on the financial capacity of your potential buyers. In Brussels, where the property market remains under pressure in 2026, an apartment listed at €350,000 generates registration duties in the region of €18,750 for the buyer after the reduction - not including notary fees.

This reality plays a role in negotiations and in the time it takes to sell. A local estate agent will be able to advise you on the listing price, taking these constraints into account. To get an initial estimate of your property's value, you can request a free valuation via IMV.

An estate agent who works regularly in Brussels understands what local buyers expect and can anticipate their questions about additional costs. This makes negotiations smoother and speeds up the conclusion of the sale.

Crossing regional borders: a significant tax difference

The gap between the Brussels rate (12.5%, with the €200,000 abatement) and the Flemish rate for your only own home (2%) leads some buyers to look towards the Flemish periphery of Brussels - municipalities such as Zaventem, Kraainem or Tervuren. For a home priced at €400,000, someone buying their only own home pays €25,000 in Brussels and €8,000 in Flanders. That difference of €17,000 can weigh on the buying decision. For cheaper homes, up to about €238,000, Brussels actually works out cheaper.

For Brussels sellers, this means there is real competition from properties located just across the regional border. This is precisely why it is important to highlight the specific strengths of your property and neighbourhood, with the support of a professional who understands this context. Compare estate agents active in Brussels to find the one best placed to showcase your property in this competitive market.
