In Brussels, and throughout Belgium, tipping taxi drivers is not mandatory and is generally not expected because the service charge is legally required to be included in the metered fare. Taxi drivers in Belgium are paid a professional wage and do not rely on tips to make a living. However, it is a very common social practice to round up the fare to the nearest Euro as a gesture of convenience and politeness. For example, if your fare is €14.60, it is standard to give the driver €15.00 and tell them to "keep the change." If the driver has been exceptionally helpful, such as assisting with heavy luggage or providing great local tips during a long ride from Brussels Airport (Zaventem) to the city center, a small tip of €1 to €2 is appreciated but will never be solicited. When paying by credit card, which is now mandatory for all Brussels taxis to accept, you can either ask the driver to add a small amount to the total or simply pay the exact amount. Unlike in the U.S., you will not be looked at poorly for not tipping, as the Belgian service culture prioritizes transparency in pricing.
