The components of notary fees

“Notary fees” is a common but misleading term. The total actually comprises several elements:

ComponentSharePurpose
Registration duties80-85%Tax to the region
Notary fees5-10%Notary’s remuneration (regulated scale)
Administrative costs3-5%Searches, certificates, filings
Mortgage fees2-5%If mortgage loan (additional deed)

The registration duties are by far the largest component. Their rate depends on the region and the nature of the purchase.

Wallonia31,250 EUR5,000 EUR~36,250 EUR~14.5%

For an investment property (not primary residence), the reduced rates are generally not available.

Investment property specifics

No reduced rate for a second property

The reduced rates (3% in Flanders, abatement in Brussels and Wallonia) apply only to the sole and primary residence. An investment property is always taxed at the full rate.

Impact on profitability

Notary fees must be factored into the profitability calculation. On a 250,000 EUR purchase, approximately 36,000 EUR in notary fees means your actual investment is 286,000 EUR. The gross rental yield must be calculated on this total.

Are notary fees deductible?

No. Acquisition costs (registration duties, notary fees, deed costs) are not deductible from rental income, either as an individual or in a company. However, they are taken into account for calculating the capital gain in case of resale (25% flat rate).
