The most costly mistake of a first purchase is to reason on the listed price. In Belgium, acquisition costs represent a significant amount that is paid in cash, at the time of the deed, and that banks rarely finance.
This article describes the structure of these costs. It deliberately gives no numerical rates: they are regional, they have been amended several times in recent years, and an outdated rate read in an article costs more than no rate at all. The official sources at the end of the article give the value in force.
Registration duties
This is the main item. It is a regional tax levied on the purchase of an existing property, calculated on the sale price.
Three things determine what you will pay:
- the Region where the property is located - Brussels, Flanders and Wallonia each have their own regime and rates;
- the use you make of it - buying your own and sole residence enjoys more favourable treatment everywhere than buying an investment property;
- the applicable reduction mechanisms: allowances on a first bracket of the price, specific regimes for energy renovation, portability of duties already paid on a previous purchase.
These regimes are subject to frequent reforms, and the eligibility conditions are precise - minimum occupancy period, absence of another property in full ownership, deadline for establishing residence. This is the point to have your notary verify before you sign a preliminary sales agreement, not after.
VAT, for new-builds
A new-build does not follow the same logic: it falls under VAT and not registration duties. The classification as "new" obeys a precise tax definition linked to the date of first occupation, and not to the visual impression of the property.
The land on which it is built may, depending on the case, follow the VAT regime or that of registration duties. On this type of transaction, the question must be settled before the offer: the difference in cost is far from marginal.
Deed fees
The notary's fees are set by law and calculated according to a degressive scale on the price: for the same property, all notaries charge the same fee. Competition therefore does not play on this item, which leaves you free to choose yours on availability and the quality of advice.
Added to this are the administrative costs - mortgage searches, land registry, town planning, transcription - which are disbursements charged back to the euro. The notary can provide a detailed breakdown.
Credit-related costs
A systematically underestimated point: if you finance the purchase with a mortgage loan, this implies a second deed, with its own costs - registration duty on the mortgage, fees, mortgage registration.
In other words, a financed purchase costs more in fees than a cash purchase, independently of the interest. Banks sometimes offer mortgage mandates that are cheaper to set up, but which have other implications: to be compared explicitly.
How to work it out before making an offer
- Identify the Region of the property and the regime applicable to your situation (own and sole residence, or not).
- Check the rate in force with the FPS Finance or your notary - not in an article, including this one.
- Ask the notary for a provisional breakdown: they provide it routinely, free of charge, on the basis of an envisaged price.
- Add the credit deed fees if you are borrowing.
- Check that this total remains available in own funds, since it is paid at the deed.
The link with the price you offer
These costs are not negotiable - they are legal or set by scale. The only lever you have is the price. Hence the value of coming to the negotiation with a substantiated estimate: knowing where the property sits within the range of its neighbourhood tells you whether there is margin, and of what order.
