Log-in information

Logging in to Altinn is personal, even when you are representing an enterprise. You will need your national ID number/user name and password for the log-in method you wish to use.

Roles and rights in Altinn

In order to fill in, sign and submit the form, you must have an Altinn role on behalf of the enterprise you represent:

If you do not have any of these roles, you must get someone else within the enterprise to delegate it to you. In Altinn, you can administer roles and rights, in addition to the delegations that have already been implemented via the Register of Legal Entities.

Contact Altinn user service if you have any problems with roles and rights or logging in.

After submission

When you submit the form, you will receive an acknowledgement from Altinn in "My message box". The acknowledgement is only a confirmation from Altinn that the statements have been submitted.

When the information has been received and registered, you will also receive feedback from the Norwegian Tax Administration in “My Message Box”. This feedback shows the statement of the delivery and any errors which should be corrected.
