I have paid money into my account. Why is the VAT missing?

When topping up your balance/depositing money, there is no VAT charge, as no service has been provided.

This process is similar to transferring funds between accounts in your bank account. There is no VAT billing there either. Only when you use a service is a service provided, and this is shown in your account with VAT. You can find these receipts for each transaction in your account under Finances. The VAT number of the service provider (if subject to VAT) is also listed on each receipt.
