Responsibility for the reclaim
Why doesn't Unzer or Payolution reclaim the VAT directly?
The Merchant who carried out the transaction is legally obliged to correct the amount of tax owed. Payolution or the Unzer Group are not authorized to reclaim the VAT directly instead of its customers and requires your cooperation.
"The relevant consideration for the tax adjustment in accordance with Section 17 UStG is determined by the actual expenses incurred by the recipient of the service, although the adjustment due to a non-payment can only ever be made by the original service provider and not by the assignment creditor."
