Fiscal subject related
Since 2015, all hoteling and catering establishments in Belgium have been required to use a tax cash register system for their sales. However, the taxpayers were given a grace period of 18 months to implement the new system, which ended on July 1, 2016.
The fiscal regulations in this country apply to all on-premise sales in restaurants or catering services provided by taxpayers whose turnover exceeds EUR 25,000. These taxpayers must register their sales with a certified cash register system that meets certain technical and security requirements. The cash register system can be either a cash register or a POS system, but it must be connected to a control module that generates and stores data for each transaction. At each sale, a receipt must be produced by the certified cash register system and given to the customer.
