As host family/employer, you must obtain the au pair's tax deduction card electronically. You can do this via This service.
The tax deduction on the tax deduction card is assessed on the basis of information concerning the amount that the au pair expects to earn and how long the au pair will stay in Norway during the income year. Holiday pay also constitutes taxable income. Tax deductions must be determined in the same way as for employees who receive a monthly salary. The tax deduction card is based on holiday pay which you pay during the year after the holiday pay has been earned (the holiday year) not being subject to withholding tax and the tax deductions being made in the other months of the year. The tax collector can provide more information concerning the rules for deductions. The Norwegian Labour Inspection Authority can provide more information on the rules concerning holiday and holiday pay.
