The amounts that the parties must pay under this GDPA are exclusive of taxes (including VAT), duties, charges or assessments which the recipient is required to collect, for which the paying party is solely responsible. Where required by law, each party shall provide the other with a valid VAT registration number and each shall fulfil its obligations relating to VAT under the applicable reverse charge procedure which, in the EU, is stipulated in Article 196 of the EU VAT Directive 2006/112/EC. If the paying party does not provide the appropriate and valid VAT registration number, or applicable documentation in support of an exemption from VAT, then the supplying party will be entitled to charge VAT at the appropriate rate until such a time as an appropriate and valid VAT registration number, or the applicable documentation, is provided, at which time the VAT charged will be refunded or otherwise credited as permissible by law, provided the VAT registration number or other exemption was valid and appropriate at the time the VAT was charged.
