Paying taxes and getting an ID/D number
Paying taxes in Norway requires that you have a national identity number (fødselsnummer) and a tax card (skattekort). If you will be in Norway for a short period, you may be issued a temporary D number. A comprehensive site called "Work in Norway" contains answers to many questions you might have.
ID number (fødselsnummer) and registration with the National Population Register
Both the national ID number and the temporary D number are 11 digits the national ID number starts with your birthdate and ends in 5 randomly generated digits. You'll need this number to get paid, to open a bank account and to pay taxes. For more information see the Norwegian Tax Authority.
You can apply for a D-number or an ID number at SUA Office. Please note that it will be required, among other documents, to have a valid property purchase contract or property rental contract valid for at least 6 months. Those who do not have such a document can expect delays in getting an ID number.
Once you have been issued an ID number, you must return to the Tax Office and apply for a tax card. It is possible to get a tax card before getting an ID number. To do so, take your job contract and passport to the tax office. An informational brochure is available there.
The tax card is used as a basis for withholding tax from salaries paid to employees working in Norway. Make sure that your employer has received your tax card before you get your first salary -- otherwise a 50% tax will automatically be withheld from your salary. If you have paid too much tax, you will get it back in your annual tax refund.
Personal tax return (Selvangivelse)
A personal tax return will be sent to your registered address in the spring of the year following the income year. The tax return is to be completed and submitted to the tax authorities by April 30 in the year following the income year. You will receive an End of the Year Certificate (Årsoppgave) from your employer with some basic information on the salary and allowances you have earned in Norway. Please include this information in your tax return.
Final tax assessment/settlement (Skattemeldingen)
The final tax assessment is sent to your registered address in either June or October in the year following the income year. It provides information on the basis for taxation in Norway, such as taxable income, tax paid, if you have overpaid or underpaid tax, etc. The tax assessment will normally correspond with the information submitted in your personal tax return, but should always be double checked.
