Closing costs for selling a home as an expat in Belgium: a seller's checklist

A checklist of closing costs is the one thing most expat sellers in Belgium ask for and rarely find. The confusion is understandable. In Belgium the buyer carries the notary bill and the registration duty, so a seller's costs sit somewhere else entirely, spread across certificates, commission and tax paperwork. This guide walks through them in the order you actually meet them, from preparing the file to the year after the sale.
What a seller actually pays in Belgium
The first assumption worth dropping is the one you brought from home. In most countries the seller settles the conveyancing bill. In Belgium the buyer pays the notary fee and the registration duty on the purchase, and the rates for that vary by region and by the buyer's own situation. None of it lands on your side of the table.
What does land on your side falls into four groups. There are the documents you have to produce before a property can legally be marketed. There is the estate agency commission, if you use an agent. There are the costs of clearing whatever is still registered against the property, a mortgage in particular. And there is the tax file that opens when a non-resident sells Belgian property, which outlasts the signing by months.
Those four groups arrive at different moments, which is why a single list of numbers is not much use. Ordering them by when you meet them makes the budget easier to plan, and it shows you where you still have room to negotiate. For the amounts themselves, our guide to the costs of selling a house in Belgium sets out the picture line by line.
Before you list: the certificates are yours to pay
A Belgian property cannot be advertised, let alone sold, without a set of documents that the seller commissions and funds. This is the first real cost, and it arrives before a single viewing.

Expect a few hundred euros for a house, less for an apartment. The soil attestation comes from the regional authority, OVAM in Flanders, with equivalent bodies in Brussels and Wallonia, and costs a modest fixed fee unless the file turns up a history that needs investigating. An electrical inspection is required for any residential unit whose installation has not been certified. A failed report does not block the sale, it simply passes the obligation on to the buyer.
Owners of an apartment have more to gather. The syndic has to supply the accounts, the minutes of recent general meetings and the state of the reserve fund, and most managing agents charge for assembling that package. If work has been carried out since you bought, the post-intervention file has to be handed over too, and reconstructing a missing one costs more than keeping it did. Our overview of what the certificates cost when selling a house goes through each one.
The mandate: commission, VAT and what is negotiable
Agency commission is the largest single line for most sellers. Rates commonly sit around 3% of the sale price, and 21% VAT applies on top, which is the part expat sellers most often forget to budget. On a property of 400,000 euros a 3% fee becomes just over 14,500 euros once VAT is added.
The rate is not fixed by law and it is negotiable, though what you should really be negotiating is the mandate itself. An exclusive mandate for a long period at a low rate can cost you more than a shorter one at a higher rate, if it locks you in with an agent who turns out not to know your street. Check the notice period, the renewal clause, and whether the fee is still owed if you find a buyer yourself.
Distance changes what you need from an agent. If you are already living abroad, the practical questions matter more than the percentage: who holds the keys, who runs the viewings, who chases the syndic, and in which language they report back to you. Comparing up to three IPI-accredited agents in your municipality costs nothing and gives you three answers to those questions rather than one. What the fee typically looks like on an expat-owned property is set out in our piece on the average agency fee in Belgium.
Between compromis and deed: what gets checked and what gets withheld
The compromis, the sale agreement, is binding in Belgium. Signing it is the moment the sale becomes real, and the four months or so that follow are when the seller's remaining costs surface.
If a mortgage is still registered against the property, it has to be released before the buyer can take clean title. That release is a notarial act with its own fee, commonly several hundred euros and rising with the amount originally borrowed. Repaying a Belgian fixed-rate loan early also triggers a reinvestment charge, capped by law at three months of interest on the outstanding balance. Both are settled out of the proceeds at the deed, so you never write a cheque, but both reduce what reaches your account.
Less visible, and more disruptive for non-residents, is the notification the notary is obliged to send. Before the deed can pass, the tax administration and the social security bodies are told the sale is happening, and they have a short window to reply with any outstanding debts in your name. Anything they claim is settled from the sale proceeds before the balance is released to you. An unfiled return from a year you were still living in Belgium, or a forgotten local tax bill, can hold up part of your money at the last moment. Clearing any open Belgian tax file before you sign is far easier than doing it under deadline.
If you cannot be in Belgium to sign
Most expat sellers do not fly back for the deed, and they do not need to. The standard solution is a power of attorney authorising someone, often a clerk at the notary's office, to sign in your name.
It is neither free nor instant. The document has to be drawn up, and if you sign it outside Belgium it usually has to be certified by a local notary and then legalised or given an apostille, depending on the country. Each step carries a fee and, more importantly, a lead time. Start it when the compromis is signed, not in the week before the deed.
Language is the second practical hurdle. A Belgian notarial deed is drawn up in the language of the region where the property lies, which means Dutch in Flanders and French in Wallonia. If you do not follow that language well enough to be bound by the text, a sworn translation or an interpreter at the signing may be needed, and you pay for it. Ask the notary early what they will accept, because practices differ between offices.
Finally, check how the proceeds will reach you. Transfers to a foreign account inside the SEPA area are routine, but some offices ask for additional identity and source-of-funds documentation before releasing a large sum, and that check can add days.
After the deed: the file that follows the sale
The signing is not the end of your Belgian administration. If you owned the property as a non-resident, you file a non-resident income tax return for the year of the sale, covering the months you still held it. Missing that return is the most common way a closed file reopens.
Whether the sale itself is taxed depends on what the property was and how long you held it. A home that served as your own residence is generally left alone. A property sold within a few years of buying it can fall into a separate charge, and the rules differ for built property and for land. The detail sits in our article on capital gains tax when selling a home in Belgium, and it is worth reading before you accept an offer rather than after.
One more piece of housekeeping. Tell the utilities, the water company and the municipality that the property has changed hands, and keep the meter readings recorded at the deed. Property tax for the year is normally apportioned between buyer and seller in the deed itself, but the bill still arrives addressed to whoever was registered as owner on the first of January.
Working through it in order
Put together, the sequence looks like this. Before listing, budget for the energy certificate, the soil attestation, the electrical inspection and, for an apartment, the syndic's package. At the mandate, budget the commission plus 21% VAT and read the exit clauses before the rate. Between compromis and deed, allow for the mortgage release, any early repayment charge, and the possibility that the tax notification holds back part of the proceeds. If you are signing from abroad, add the power of attorney, its legalisation and any translation. After the deed, file the non-resident return.
None of it is unpredictable, but it is front-loaded, and the items you pay first are the ones you pay whether or not the sale completes. That is a good reason to know what the property is realistically worth before you commit to the spend. A free valuation gives you that figure, and if you then want local opinions on how the file should be handled from a distance, you can compare up to three agents in your area free of charge and with no obligation.
Frequently asked questions
Who pays the notary fees when selling a house in Belgium?
The buyer pays the notary fee and the registration duty on a Belgian property purchase. The seller's notarial costs are limited to releasing any mortgage still registered against the property, and to a power of attorney if the seller cannot attend the signing.
What does an expat seller pay before listing a property in Belgium?
Before a Belgian property can be advertised the seller pays for the energy performance certificate, the soil attestation, an electrical inspection where the installation is not yet certified, and, for an apartment, the documents supplied by the syndic. These are paid whether or not the sale completes.
Can I sell a Belgian property without travelling to the signing?
Yes. A power of attorney lets a representative, often a clerk at the notary's office, sign the deed in your name. Signed abroad it normally needs certification by a local notary and then legalisation or an apostille, so it should be started when the compromis is signed rather than in the final week.
Why can a notary hold back part of the sale proceeds from a non-resident seller?
Before the deed passes, the notary must notify the Belgian tax and social security authorities of the sale. Those bodies have a short window to report outstanding debts in the seller's name, and the notary settles them from the proceeds before releasing the balance.
