According to EU regulations, all customers located within the EU are required to pay VAT unless they have a valid VAT ID, in which case they are exempt from VAT.
Purchases made through PayProGlobal by EU shoppers are subject to a VAT rate according to the customer's country of residence or establishment.
Sales made by PayProGlobal to shoppers established in Iceland, Norway and Switzerland (outside of the EU) are subject to each country's VAT.
For EU countries, If you place the order as a private person, it will charge you VAT.
If you place as a company, it should not charge you VAT, if you pay intra-communitary taxes.
The verification of the VAT exemption number is carried out through the VIES service, a system for checking the validity of VAT registrations
