The option to deliver VAT returns on paper is no longer available with effect from January 1 2016. This imply that the VAT return for term 1 (January and February) which is due April 10 must be submittet electronically through Altinn.no

Who can submit VAT returns?

In order to submit VAT returns in Altinn you must have a person with a Norwegian personal number or a D-number in Norway to access Altinn. The general manager and the chairman of the board are granted access to submit VAT returns electronically. It is also possible to delegate the right to submit the VAT returns to e.g. an accountant.

First time log on is not that easy

The first time you log on to Altinn it is required that you are able to identify yourself. If you are a foreigner a pin-letter is sent to your home address. This pin is activated after you have verified your ID to Altinn. This implies that you must have e.g. a notorious publicus verifying your ID papers.

Thus, I recommend that you start the process now in order to be able to deliver your VAT return in due time.
