Why does Belgium have three different regimes?
Many buyers are surprised to learn there is no single rate for registration duties in Belgium. Buying in Liège, Antwerp or Ixelles doesn't cost the same in taxes — for exactly the same sale price.
The reason is constitutional. Since the 5th State reform (2001), real estate taxation has been transferred from the federal level to the regions. Each of the three entities — Flemish Region, Walloon Region and Brussels-Capital Region — freely sets its own rates, rebates and conditions.
In 2026, for a house at 300,000 €, you pay 6,000 € in Flanders, 9,000 € in Wallonia and 12,500 € in Brussels (with rebate). A gap of more than 6,500 € on the same transaction.
It's no coincidence each region now has its own fiscal slogan: Flanders wants to attract young families, Wallonia reformed in 2025 to catch up its lag, and Brussels tries to keep its inhabitants in the capital via the rebate.
The master comparison — all regions, all cases
Here is the table summarizing all applicable rates in 2026, by region and by purchase type.
Flanders is unbeatable for the main residence but heavily taxes building plots. Wallonia is the most coherent: 3% for both housing and land intended to build the main residence on. Brussels remains the most expensive but rewards energy renovation projects with a unique mechanism in Belgium.
This guide gives the federal overview. For the precise detail (exact conditions, procedures, pitfalls), each region has its dedicated article:
How does this tax actually work?
Before comparing rates, it's essential to understand what exactly a registration duty is. Many people confuse it with notary fees — these are two different things.
A registration duty is a regional tax due upon official registration of an authentic real estate sale deed. This registration makes the deed enforceable against third parties — i.e. legally protects you as the new owner.
Concretely, here's how it works:
Registration duties are a tax paid to the region. Notary fees are remuneration for service, set by an official tariff (around 1 to 2% of the price). On top of these two come hypothecary transcription fees and various administrative fees. Overall, we often speak of "purchase costs" rather than "notary fees" to avoid confusion.
Brief history — where does this system come from?
The registration duty isn't a Belgian invention — it dates back to the French period (the Napoleonic Code of 1804 laid its foundations). But its current strongly regionalized structure is recent.
| Year | Evolution |
|---|---|
| 1939 | The single 12.5% rate is set for the whole country. It will remain unchanged for several decades. |
| 2001 | 5th State reform. Competence is transferred from federal to the three regions. Each can now set its own rules. |
| 2002 | Brussels and Flanders introduce their first rebates to encourage homeownership. |
| 2018 | Flanders simplifies its system with a single 7% rate for the own home — end of the progressive calculation. |
| 2022 | Flanders drops to 3%. First strong regional signal of fiscal competition between regions. |
| 2025 | Flanders moves to 2% (lowest in Belgium). Wallonia carries out its major reform: 12.5% → 3% for the own home. |
| 2026 | The new rates are fully in force. Brussels announces a future rebate ceiling raise from 600,000 € to 800,000 € (planned for 2029). |
This evolution illustrates a political phenomenon: for the past decade, Belgian regions have used registration duties as a policy lever. Attracting residents, supporting the purchasing power of young people, encouraging energy renovation — all goes through this fiscal lever.
Who decides? Who collects? Where does the money go?
A legitimate question when you pay tens of thousands of euros: who gets this money and who decides how to use it?
Four concrete scenarios by profile
Rather than a theoretical calculation, here's how registration duties apply to four typical profiles we actually encounter.
First purchase, no other property, the home will become the main residence.
Already owns a property but commits to selling it within each region's legal deadline.
if sold within 2 years
if sold within 3 years
if sold within 2 years, rebate after the fact
Buying for rental, keeps main residence elsewhere. No reduced rates accessible.
12%
12.5%
12.5%
Belgian who lived abroad, owns no other property (in Belgium or elsewhere).
note: Flanders also checks foreign properties
with rebate
For the same 300,000 € property, the buy-to-let investor pays 4 times more than the first-time buyer in Flanders (36,000 € vs 6,000 €). In other words: your status (first-time buyer or not, main residence or not) often matters as much as your region.
The special cases nobody tells you about
A few specific situations that don't depend on the region but on federal rules — therefore identical throughout Belgium.
New build sold by a developer
If you buy a new build from a developer (within 2 years of first occupation), the transaction is subject to 21% VAT, not registration duties. Only the land may, in some cases, remain subject to registration duties. This rule is federal and applies to all three regions.
Donation and inheritance of real estate
When a property is transferred (donation between living persons or inheritance), it isn't the registration duties at 2/3/12.5% that apply — but donation or inheritance taxes, which are also regionalized but with a totally different tariff structure (often progressive based on family relationship). That's another topic.
Purchase via a company
If you buy via a company (BV/SRL, NV/SA…), you cannot benefit from reduced rates. The region's standard rate applies (12% in Flanders, 12.5% in Wallonia and Brussels). A point often poorly anticipated by self-employed individuals.
Purchase in dismemberment (usufruct / bare ownership)
If you only buy bare ownership or usufruct, reduced rates generally don't apply. Regions require the acquisition of full ownership to benefit from the lowest rates.

A few terms you'll systematically encounter in contracts and that many people only discover at signing.
Summary in 5 points
- Three regions, three regimes: 2% in Flanders, 3% in Wallonia, 12.5% in Brussels with rebate.
- Since 2001 the competence is regionalized: each region sets its rates and mechanisms.
- The notary always collects, then forwards the duties to Vlabel or FPS Finance depending on the region.
- Your profile often matters more than your region: first-time buyer vs investor = factor 4 on the amounts due.
- Federal rules apply everywhere: new-build VAT, donation, inheritance, company purchase.
