Wallonian property owners are expressing bewilderment after receiving their property tax notices—known as the avertissement-extrait de rôle or AER—earlier than usual this year, sparking concerns over potential double taxation within a single calendar year.
The Service public de Wallonie (SPW) distributes roughly 1.6 million AER notices between early July and early October, averaging between 150,000 and 200,000 dispatches per week, according to RTL Info. Rather than operating on a municipality-by-municipality basis, the administration organizes these shipments progressively across 1,639 cadastral divisions in Wallonia.
The Mechanics of Cadastral Dispatches and Taxpayer Frustration
Antoine, a resident of Chaumont-Gistoux, voiced his concerns to RTL Info regarding the legality of this shift and what might happen if the pattern repeats. “You’ll soon have to pay twice in the same year if it shifts by two months each time,” he warned through the outlet’s orange Alertez-Nous button.
Tony, living in Waterloo, experienced a similar surprise when his AER arrived well before the usual period. Criticizing the regional administration for a lack of advance notice, he noted that the unexpected timeline disrupts household financial planning.
Nicolas Yernaux, spokesperson for the SPW, addressed the confusion by emphasizing that the administration has altered no core procedures. The delivery schedule varies naturally because the agency structures dispatches in successive waves dictated by technical and administrative parameters. While some property owners receive their bills earlier than in previous years, others will receive theirs later.
Property Tax Must Be Paid Within Two Months
Regardless of when an AER arrives in the mailbox, the legal payment window remains fixed at two months from the date of dispatch, as detailed by RTL Info. For instance, if an notice carries an issue date of September 16, the property tax must be settled by November 16. The timestamp printed on the document determines compliance, not the physical delivery date.
Failing to meet this deadline triggers statutory late-payment interest calculated at the legal tax rate, which begins accumulating on the first day of the month following the due date.
