Prices include 21% VAT.
It is required by the local authorities that we charge local VAT, hence the reverse charge mechanism does not apply and it is therefore not possible for attendees, that are taxable persons in another EU country or established outside EU, to receive an invoice without local VAT. However, it cannot be excluded that local regulations may apply, e.g. exemption of VAT, such as the admission fee from a local VAT point of view is considered as VAT exempted educational services.
If local VAT is levied on the admission fees, it may be possible for you to reclaim the VAT in your business, either via your VAT return if you are registered for VAT in Holland, alternatively via the VAT refund scheme cf. 8th and 13th EU Directive.
