Surcharges and reductions

A surcharge or a reduction can be indicated for the entire invoice or for each invoice line item. All surcharges and reductions have effect when calculating the VAT. In the online form surcharge and reduction only can be entered on item level. For each position only one surcharge or reduction can be provided as an absolute value (before tax).

Examples for common surcharges and reductions:

  • advertising tax
  • beer tax
  • visitor’s tax
  • copper surcharge


  • The words reduction and discount are synonymously used.
  • The NOVA (Standard fuel consumption tax) is another tax and cannot be inserted in the online form in a separate field.
