Tax returns deadlines: summary table of deadlines applicable as from the 2024 assessment year
Written By
Until recently, tax return deadlines in Belgium were essentially governed by administrative decisions that could vary from year to year (although a number of legislative rules did exist, for example a minimum period of time allowed to the taxpayer between the date of receipt of the tax return form and the date of submission). Since the 2024 tax year, the deadlines are now all set out in law. They vary according to the taxpayer's situation, and whether he or she is filing on a paper form or online (this choice now only exists for individuals). A summary table is provided below.
