Start by choosing which level of membership is appropriate for you. Once you have completed the application process, an invoice will be generated with the appropriate BTW (VAT) amount added, if applicable. The invoice will also contain instructions on how to transfer the membership fee to our bank account. If you are joining from a country within the EU where BTW (VAT) should not be applied, please provide your VAT number. If you are joining from outside the EU, BTW(VAT) will not be charged.
