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 3% for primary residences since 2022, while Wallonia maintains a rate of 12.5% with its own reduction mechanisms. Brussels therefore remains the region with the highest rate, which makes it all the more important to understand the reductions available.

The Brussels Tax Reduction: Up to €22,500 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.

This reduction represents a saving of €25,000 (12.5% of €200,000). Bear in mind, however, that the reduction is scaled back if the property's value exceeds a certain threshold: above €500,000, it no longer applies.

To benefit from this reduction, the buyer must:

• Register at the property's address in the population register within two years of purchase.
• Not own any other property in full ownership at the time of signing the deed.
• Establish their primary residence in the acquired property for at least five years.

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 Brussels rates (12.5%) and Flemish rates (3%) leads some buyers to look towards the Flemish periphery of Brussels - municipalities such as Zaventem, Kraainem or Tervuren. For a property priced at €400,000, the difference in registration duties can reach €38,000, which is a compelling factor in the buying decision.

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.
