What costs do you pay when buying property in Belgium in 2026?

Resale homes normally attract registration duties (registratierechten / droits d'enregistrement), a regional tax collected through the notary. FPS Finance explains the split: Flanders administers its own duties, while Brussels-Capital and Wallonia still use FPS Finance collection for many deeds.

Durable planning anchors, always confirmed with the notary for your exact file: Brussels-Capital and Wallonia commonly use a 12.5% base rate on qualifying transfers, with reliefs for a main residence under stated conditions (Wallonia's reduced main-residence track is often discussed at 3%). Flanders uses a different schedule, with a sharply reduced rate for an only own home that meets Vlabel conditions, and a much higher rate for other purchases. New builds sold as a first transmission from a developer often sit under VAT (commonly discussed at 21% on the building part, with reduced rates only in narrow cases) instead of registration duties. You follow one main tax route or the other, not both.

Notary fees follow a regulated declining scale plus administrative outlays and VAT on the professional fee portion. Ask for a written estimate early. If you finance, add mortgage registration duty (often discussed at 1% of the secured amount in Brussels guidance), writing fees and a separate mortgage deed cost stack. Technical surveys, buyer's agent fees where used, and certificate packs (EPC / PEB and others) also belong in the cash plan.

Co-ownership apartments add a first look at syndicus charges and planned works before you treat the purchase as "cheap versus rent." Compare long-term carrying cost with rent in Belgium and your monthly budget.

Expect the annual précompte immobilier / onroerende voorheffing (property tax) calculated from cadastral income, plus any regional or communal additions. Apartment owners also pay recurring co-ownership charges. Renovation and heating upgrades on poor EPC / PEB stock can dwarf a small negotiation win on the purchase price, especially in older Brussels or Flanders brick streets.

Non-resident landlords face separate Belgian tax reporting on Belgian property income. Buying still does not create a residence right; lock immigration separately if you plan to live in the home.
