On the 1.1.2010 the new Vat law changed in Norway. Up until this point it was in the regulations authorized a tx exemption for stand rental and associated services to foreign businesses. This regulation is not longer in process by the new VAT rules, and stand rental and associated services to foreign businesses will be regarded as ordinary taxable supplies.
The reason for this is that the stand rental and associated services is a service provided in Norway. Since Norway is not a member in EU, the regulations are different from countries that are members of EU. Foreign businesses that make use of this service will therefore be dependent on a refund for the tax paid, ahead the event.
