If you stay in Norway for more than 183 days in a twelve-month period or more than 270 days in a thirty-six-month period, you will become a tax resident in Norway. All full or partial calendar days with a stay in Norway are included when calculating the number of days. If you have become a tax resident, this will only cease after you have applied for and received a decision on tax emigration. Tax residency does not cease when you move or when you take up residence in another country.
