Parkmobile charges VAT (21%) across all service fees, including registration fees, transaction costs, reminders and additional cost for ordered Parkmobile tokens or stickers.
Street parking is regulated by the municipality & includes tax money, therefore you do not need to pay VAT. The city of Antwerp is the only exception, here you need to add VAT to street parking also. If you park your car on an enclosed area, for example, a parking lot, you will have to pay the VAT of 21%.
If you have credit card as a method of payment, you have to pay the surcharge of 3% VAT (21%).
