21% Dutch VAT will be added to all ticket prices. Tickets can be paid via credit card, iDEAL or our other online payment options. Bank transfer payments will not be possible this year.

We expect all our attendees to be aware of our code of conduct.




Article 53 of the European VAT directive requires us to charge VAT even to foreigners:

"B2B services in respect of admission to cultural, artistic, sporting, scientific, educational, entertainment and similar events will be taxed at the place where those events actually take place."


If you want to visit the Netherlands for a short stay (up to 90 days), you might need a visa. How you apply for a visa depends on your country.

See Applying for a short-stay Schengen visa for more information.
