What do electronic tax deduction cards entail for you as an employer? You can order tax deduction cards for your employees via your payroll system or via skatteetaten.no. You will be notified if any of your employees amend their tax deduction cards and you are responsible for updating the tax deduction card details for the next payroll run. You need to have access to employees' national ID numbers/D numbers in order to obtain electronic tax deduction cards for them. You are only permitted to obtain electronic tax deduction cards for persons you are going to make taxable payments to. Your employees will be notified that you have obtained tax deduction cards for them. If you are unsure whether you are your employees' main employer or a secondary employer, you must clarify that with them. This only applies to employees with table-based cards.
