Foreign employees who are staying and working in Norway for short periods are assigned D numbers.
If the stay is temporary, they will only receive a tax deduction card for the current year. At the start of the new year, the employee must apply for a new tax deduction card. Once a tax deduction card application has been processed, you can obtain it electronically.
When a taxpayer is issued with a tax deduction card, you will be notified if you have previously attempted to obtain it.
