Registration Duties in Belgium: Everything You Need to Know in 2026

Registration duties are an unavoidable tax charge when buying property in Belgium. The amount varies depending on which region the property is located in, the buyer's profile, and the nature of the transaction. Before signing a preliminary sale agreement, it pays to understand exactly what you will owe - and in which circumstances you may qualify for a reduced rate or a tax reduction.

What Are Registration Duties?

Registration duties are a regional tax levied when a notarial deed of sale for a property is registered. They are calculated on the purchase price or on the market value of the property, whichever is higher. In practice, it is the buyer who pays them, and they fall due at the moment the authentic deed is signed before the notary.

In Belgium, the tax competence over registration duties has been transferred to the Regions. This means that the applicable rate depends on the Walloon, Flemish, or Brussels-Capital Region in which the property is located - not on the buyer's place of residence. The differences between regions can be significant, and they have a direct impact on the total cost of your purchase.

Registration duties should not be confused with VAT. When you buy a new-build property from a developer, you pay VAT at 21% (or 6% under certain conditions) and not registration duties. The two regimes are entirely separate.

Rates in Force by Region in 2026

The base rates differ across the country's three regions. Here is an overview of the situation in 2026.

In the Flemish Region, the standard rate is 3% for a property that will serve as the buyer's sole and own home, following the reform that came into force in 2022. For other acquisitions - a second home or a buy-to-let investment - the rate is 12%. The reduction to 3% was a major reform: previously set at 6%, it was lowered to make home ownership more accessible. An additional reduction of 2,400 euros applies under certain conditions for first-time buyers or buyers of a modest property.

In the Walloon Region, the standard rate is 12.5%. A reduced rate of 6% applies under certain conditions for modest housing. Partial reductions also exist for first-time buyers, for properties located in certain priority revitalisation zones, and for properties that undergo energy-related renovation works. Wallonia has also introduced the concept of a tax abatement on the base tranche of the purchase price in certain cases.

In the Brussels-Capital Region, the general rate is 12.5%. An abatement of 200,000 euros on the taxable base is granted to buyers who commit to establishing their primary residence in the property and who do not own any other property in full ownership in Belgium at the time of the deed. This abatement can represent a concrete saving of 25,000 euros on the registration duties owed.

Reductions and Exemptions You May Be Entitled To

Each region has put in place mechanisms to ease the tax burden on buyers in certain situations. It is important to check whether you qualify before signing the deed.

In Flanders, in addition to the reduced rate of 3%, you may benefit from an abatement on the first 50,000 euros of the purchase price if the property will be your sole and own home and its market value does not exceed a certain ceiling. For properties located in a high-pressure property zone, the abatement can reach 100,000 euros.

In Wallonia, the 6% rate for modest housing applies when the cadastral income of the property does not exceed certain thresholds. These thresholds are increased depending on the number of dependent children. In addition, Wallonia grants a reduction in duties when the buyer commits to carrying out energy improvement works within five years of the purchase, in line with the renovated housing cheque (chèque-habitat rénové) scheme.

In Brussels, the 200,000 euro abatement is the main benefit available. To qualify, you must commit to establishing your primary residence in the property within two years of the deed, and to maintaining that residence there for at least five years. If you fail to honour this commitment, you will be required to repay the tax benefit received, plus a financial penalty.

How Are Registration Duties Calculated in Practice?

The calculation is straightforward in principle. Registration duties apply to the purchase price or to the market value of the property, whichever is higher. The notary is required to verify that the declared price reflects market reality. If the tax authority considers that the property has been undervalued, it may reassess the taxable base.

Here is a concrete example. You buy an apartment in Brussels for 350,000 euros. You are entitled to the 200,000 euro abatement. The taxable base is therefore 150,000 euros. At the rate of 12.5%, you pay 18,750 euros in registration duties, instead of 43,750 euros without the abatement. The saving amounts to 25,000 euros.

In Flanders, for the same property at 350,000 euros, with the 3% rate for a sole and own home, you pay 10,500 euros. The difference compared with Wallonia or Brussels is therefore considerable.

These amounts are on top of the notary's fees, deed costs, and - where applicable - the estate agent's fees. It is advisable to budget between 10% and 15% of the purchase price to cover total acquisition costs, although this percentage varies depending on the region and the buyer's personal circumstances.

Registration Duties and Selling Your Property: What It Means for You as a Seller

As a seller, you do not pay registration duties directly. It is the buyer who is liable for them. However, this tax burden indirectly affects your position on the market. A buyer who has to pay 12.5% in duties has a tighter overall budget than a buyer subject to 3%. This can weigh on the price they are willing to offer for your property.

Understanding the tax profile of your potential buyers helps you adjust your sales strategy. For example, if your property is likely to be purchased as the sole primary residence by a first-time Flemish buyer, you can highlight the tax advantages they will benefit from. This can make your property more attractive compared with other options on the market.

To sell at the best price and on the best terms, it is advisable to work with an estate agent who has a thorough knowledge of the local market and the tax specifics of your region. Comparing estate agencies near you is a useful first step towards finding the professional best suited to your situation.

Can Registration Duties Be Reduced Through a Reinvestment?

Yes, in certain cases. The reinvestment mechanism - also known as the portability of registration duties - allows a buyer who has already paid duties on a previously sold property to deduct all or part of those duties from the duties owed on the new property. This mechanism exists in both Flanders and Wallonia, subject to different conditions and caps.

In Flanders, the so-called "meeneembaarheid" mechanism allows duties paid on the sale of a former home to be carried over to the purchase of a new one, up to a ceiling of 13,000 euros. To benefit from this, the purchase of the new property must take place within a set period relative to the sale of the previous one.

In Wallonia, a similar mechanism exists under certain conditions - in particular if the buyer purchased their previous property before a reference date and it was their main residence. The rules change regularly, so it is advisable to consult a notary or check with the Walloon tax authorities before planning your transaction.

Common Pitfalls to Avoid When Calculating Registration Duties

Several frequent mistakes can lead to unpleasant surprises at the moment of signing the notarial deed.

The first concerns market value. If you buy a property below the market price, the tax authority can recalculate the duties on the estimated real value rather than the price paid. This happens in particular during transactions between acquaintances or when a property is sold very quickly after a high-price purchase.

The second mistake involves the conditions that must be met in order to benefit from a reduced rate or an abatement. These conditions must be fulfilled at the time of the notarial deed, and some must be maintained for several years after the purchase. Failing to honour the commitments made results in the repayment of the benefits received, plus penalties.

Third, in the case of a new-build or off-plan purchase, care must be taken not to confuse the value of the land with the value of the construction. In such cases, VAT applies to the construction element, while registration duties apply only to the land value. This distinction can significantly alter the overall calculation of acquisition costs.

Finally, if you are buying a property to rent out, check whether any specific tax arrangements apply in your region. In Wallonia, for example, certain purchases intended for renovation followed by letting under a regulated tenancy agreement may open entitlement to reductions on registration duties.

For any questions specific to your situation, a notary remains the most qualified point of contact. As far as selling your property is concerned, comparing estate agents in your region will help you obtain the best local advice and optimise your transaction as a whole.
