Notary fees: how much does it really cost?
In Belgium, buying an existing property adds 10 to 15 % to the price on average in fees: notary fees, registration duties and disbursements. Here's a precise estimate based on your situation.
1. Notary fees
Decreasing scale set by royal decree — identical at all Belgian notaries. You cannot negotiate this part. 21 % VAT is added.
2. Registration duties
Regional tax, the largest item (12.5 % standard in Brussels, 3 % in Flanders for own residence). See the dedicated calculator.
3. Disbursements and administrative fees
Mortgage searches, cadastral extracts, registration fees, urban planning checks. Average flat fee: ~€1,800. Varies depending on the file.
New property: replace the duties with 21 % VAT on the ex-VAT price. This calculator only covers existing property.
