No. If you rent a home in Belgium as your main residence, your landlord cannot pass the property tax — précompte immobilier in French, onroerende voorheffing in Dutch — on to you. This holds in all three Regions: Flanders, Brussels and Wallonia. The rule is mandatory law, which means a clause in your lease saying otherwise is void. You do not have to pay it, and if you already have, you can ask for your money back.

This catches out a lot of people renting in Belgium, and international tenants in Brussels especially — the tax bill arrives in Dutch or French, it looks official, and a line in the lease seems to say it is yours. It is not. Here is exactly what the law says, when passing it on is allowed, and the reduction most tenant households never claim.

What does the law say in each Region?

Belgian rental law was regionalised in 2018, so there is no single national text. All three Regions landed on the same rule:

Region	Legal basis	What it says
Flanders	Article 36, §1 of the Flemish Residential Lease Decree (Vlaams Woninghuurdecreet)	The property tax on the rented property cannot be charged to the tenant.
Brussels	Article 226 of the Brussels Housing Code	The property tax on the rented building cannot be charged to the tenant under a main-residence lease, a student lease, a co-tenancy lease or a sliding lease.
Wallonia	Articles 59, 73 and 83 of the Decree of 15 March 2018 on residential leases	The same sentence, repeated for the ordinary residential lease, the co-tenancy lease and the student lease.

In Wallonia, article 74 states explicitly that these provisions are impératives — mandatory. The parties cannot validly contract around them, even where the tenant has signed.

Why is it forbidden?

The reasoning is a principle the Flemish decree spells out in that same article 36: costs and charges connected to the exercise of property rights over the home are the landlord's, while costs and charges connected to using the rented home are the tenant's.

Property tax is a tax on owning real estate. It is due because someone owns the building, not because someone lives in it. So it sits structurally on the owner's side of the line — just as the tenant pays for electricity because the tenant consumes it.

What if the clause is in my lease anyway?

Then the clause is void. A signature does not rescue a prohibited clause — that is exactly what "mandatory law" means. In practice:

• Not yet paid? Write to your landlord, cite the article that applies to your Region, and state that you will not be paying that item. Use email or registered post so you have a record.
• Already paid? That is a payment that was never owed, and you can ask for it back. Request it in writing with your proof of payment attached.
• Stuck? The justice de paix / vrederechter (justice of the peace) for the canton where the property is located handles rental disputes. In many municipalities you can first get free help from a tenants' association or the first-line legal aid service.

One nuance worth understanding: your landlord may not invoice the tax separately, but may of course take it into account when setting the rent itself. That is not a loophole — it is the difference between a price and a passed-through tax. What is not allowed is a separate "property tax" line on your annual charges statement.

When can the property tax be passed on?

The prohibition applies to residential leases. Outside that scope, ordinary freedom of contract applies and passing it on is possible if expressly agreed:

• commercial leases and offices;
• a second home or holiday property;
• storage, garages and land not let as housing.

Even then, the owner remains the party liable to the tax authorities. The lease only decides who ultimately bears the cost; it does not move the tax debt. If the tenant does not pay, the tax administration still comes to the owner.

For a mixed-use building — a shop with an apartment above it, say — only the professional part can be passed on contractually. The residential part stays covered by the prohibition.

The reduction most tenant households never claim

This is the part almost nobody knows about, and it is real money. Belgian property tax carries reductions that depend on the household situation of whoever lives in the property — not the owner's. If a tenant household includes dependent children or a person with a disability, the owner's tax bill goes down because of the tenant. The law makes sure that benefit reaches the tenant.

Flanders

Article 2.1.5.0.1, §1 of the Flemish Tax Code (Vlaamse Codex Fiscaliteit) grants a reduction for a household with at least two children qualifying for child benefit, and a reduction per person with a disability — a child with a disability counts double. The per-child amount is indexed annually. Article 2.1.5.0.4 of the same code then settles the question: these reductions are deductible from the rent, notwithstanding any clause to the contrary. The tenant may withhold the amount from the rent, and a lease clause forbidding it has no effect.

Brussels

Article 226 of the Brussels Housing Code goes further and puts an active duty on the landlord. For households covered by article 257 of the Income Tax Code, the landlord must apply for the reduction on the tenant's first request, once the tenant has supplied the relevant information. The reduction is owed to whoever occupies the property on 1 January, and the landlord must pass it to the tenant household before the end of each rental year — either as an equivalent rent reduction or as a separate payment.

Wallonia

In Wallonia the reductions are not applied automatically: they must be applied for with SPW Fiscalité, using the dedicated form or online. If you rent with dependent children or a person with a disability in the household, tell your landlord in writing and ask them to file the application. The reduction depends on your household situation, so without your details the owner cannot obtain it.

What should landlords do instead?

1. Take the clause out of your lease template. Plenty of older templates circulating online still carry a "property tax borne by the tenant" line. It is unenforceable, and it starts a new tenancy on the wrong foot.
2. Build the cost into the rent, not the charges statement. Work out your yield with the property tax included and set the rent on that basis. See our guide on Belgian lease durations for how the rest of the contract fits together.
3. Keep the charges statement clean. Only genuine usage costs belong there. Repair responsibilities are set out in who pays for repairs — landlord or tenant, and indexation is covered in how much your landlord can increase the rent.

One important note: this is not legal advice

This article is general information based on the texts in force at the time of writing (the Flemish Residential Lease Decree, the Brussels Housing Code, the Walloon Decree of 15 March 2018 and the Flemish Tax Code). It is not legal advice and does not account for your specific circumstances. For a concrete case, consult a lawyer, a notary, a tenants' association, or your municipality's first-line legal aid service.

Keeping the rental file straight

The difference between a charges statement that gets accepted and one that gets disputed is almost always the paperwork: which charge belonged where, what was indexed and when, and what was actually agreed. ImmoDesk keeps your leases, charges, indexations and documents in one place, so you can show where any figure came from. See our accounting module and the rent indexation calculator.
