The Norwegian Tax Administration offers test submission for statement submitters and submitters who must submit statements as a file attachment via Altinn.
By taking part, you will be able to test the entire value chain. It is now possible to test during the whole year. Register to take part in the testing by sending an e-mail to email@example.com. In your e-mail, state the organisation number of the statement submitter and where applicable the submitter, as well as the name, e-mail address and telephone number of a contact person for the test submission.
You will be allocated a fictitious test user, which is used to log in to Altinn’s test environment. You will find more information on testing here.
