VAT return

Boxes calculated from your invoices, not copied out by hand.

FactOne allocates each transaction to the boxes of the Belgian periodic VAT return and produces the XML file to be filed on Intervat. Once saved, the return is kept exactly as it was in your history.

FactOne prepares: filing on Intervat is still done by you or by your accountant.

How FactOne prepares your VAT
Example — Q3 2026 Intervat file ready
VAT return boxes (example)
