How the 2026 tax refund works in Belgium

Reductions also lower the municipal surcharge (7%). Donations count from €40 a year per institution; childcare for children under 14 at up to €16.90 a day (latest published amount). Service vouchers no longer give a reduction in Flanders and Brussels and are left out. The return is filed in spring 2027 (Tax-on-web or MyMinfin).

Estimate with the most common items only, for one person filing alone; your own return can include more, and the tax office decides the final amount. Not tax advice.
