What is the allowance and how much can you save with it?
The allowance works as an exemption on the first part of your purchase. Specifically: on the first €200,000 you pay 0% registration fees. At 12.5%, that is a saving that can amount to € 25.000. Suppose you buy a home from € 450.000 and you qualify. Then the tax is not calculated on the full amount, but on € 250.000. You immediately feel the effect in the calculation: fewer registration fees often means requires fewer own resources and a lower total cost. How much can you save with it? The maximum benefit is 25,000 euros (12.5% on 200,000 euros). In practice, the amount depends on your purchase price and whether you remain within the regime. The upper limit today is 600,000 euros. If you go above that, the advantage basically disappears. The scheme that has been in effect since April 1, 2023 will continue to apply in 2026. That ceiling is not a detail. In many files it determines the final choice of unit or budget.

The broad lines are clear:
- The house is located in the Brussels Capital Region.
- You buy as a natural person and become full owner.
- At the time of signing, you do not own any other home in full ownership, subject to specific exceptions.
- You establish your main residence within three years.
- You will live there for at least five years.
- The purchase value remains below 600,000 euros.
The allowance is linked to effective occupancy. Anyone who buys as an investment falls outside this framework. Anyone who owns another home at the time of purchase but sells it within two years can obtain the allowance through reimbursement. This requires correct timing and follow-up in the file. Since April 1, 2023, there has been a relaxation in the event of non-compliance with the five-year occupancy obligation: the benefit is reclaimed proportionately instead of in full.
Does the allowance also apply to new construction and building land?
Yes, but the application is different than many buyers expect. For new construction off plan, the allowance only applies to the part on which registration fees are due, usually the land share. The construction part is subject to VAT. That difference is technical, but financially relevant. The benefit is therefore not calculated on the full purchase price. If you only look at this when the deed is signed, it is too late. It belongs in the budget analysis when making a reservation. And for building land? Yes. There is also an exemption for building land, but on the first 100,000 euros of the purchase basis. The benefit can also increase there, but the calculation basis differs from a classic home. It is therefore important that your notary or file supervisor calculates it correctly based on your situation.
Why does the limit of 600,000 euros play such a major role?
The allowance remains a strong lever for private occupancy, provided that:
- the budget remains below the threshold
- the move planning is realistic
- no other home is maintained outside the permitted exceptions
It doesn’t matter for investors. There the analysis shifts to returns, rental market and value retention. That distinction must be clear in advance. Not every buyer buys for the same reason, and the tax framework follows that choice.
What does this mean specifically for YOBO projects in Brussels?
At YOBO we notice that the abatement in Brussels often shifts the conversation from “can I afford this?”to “which unit best fits my total costs?”. Take Pagode in Laeken. Laeken is popular with buyers who want to combine Brussels with breathing space: living comfort, accessibility and a clear price logic. In such cases, the allowance often serves as a lever to optimize the budget: it is not only the purchase price that counts, but the sum of registration fees + own contribution + monthly costs. Also at August in Oudergem you see the same mechanism, but with a different dynamic. Oudergem is in a market where prices per m² are structurally higher. That makes the €600,000 limit even more noticeable. Buyers then not only compare units, but also scenarios: which layout provides the best living quality within the regime, and where is the tipping point at which the advantage disappears? The same reality applies in both projects: the allowance is not an afterthought. It is a budget variable that you should include in your first simulation, even before booking.

The allowance is not a precondition. It is a structural part of the Brussels purchasing logic. Anyone who buys less than 600,000 euros to live in themselves can pay up to 25,000 euros less registration fees. Anyone who goes above or does not meet the occupancy conditions will not. In a market where affordability is under pressure, that difference is substantial. Not because the system is generous, but because the boundaries are sharp. And in Brussels, sharp boundaries often make the difference between reckoning and suffering.
