Belgium has a multitude of e-government solutions. Local residents have now ID cards in the form of a banking card with a chip, there are services to order certificates online with these cards, pay taxes and check for medicines.
Last week, I was struggling with the Intervat, an online system for entering various VAT declarations. I had no clients outside belgium, so I tried to enter an empty declaration for inter-country transfers when the application displayed an error saying that "the declaration has to contain minumum one client.".
To make sure, I asked the support whether I should send an empty declaration, and got the reply that I have to resubmit my declaration. To top it all, the reply was in Dutch, although my question was in French. I am still trying to figure what to do, and the deadline for the declaration is today.
