Belgian companies need to annually file a VAT list with all Belgian tax dutiful customers listed by enterprise number, their turnover and the total VAT amount charged. The report is to be generated as an xml file and has to uploaded to the Intervat website.
A report is available for this in D365FO (menu Tax, report 'invoice turnover report - Belgium') and an ER format (Invoice turnover report (BE)). This works fine in legal entities with just one VAT number.
When using multiple VAT registrations there is no option to link the report to just one of the company's registration ID's as you can do with the VAT declaration, the EU sales list and the Intrastat declaration.
The result is that in the annual listing all turnover to Belgian customers is included, not limited to the sales done from the company's Belgian VAT number.
The Belgian annual VAT listing is a legally required declaration, just like the monthly declaration, EU sales list and Intrastat, therefor it should be supported by multi VAT as well.
