Tax Residency Rules in Norway (in simple language)
You're a Norwegian tax resident if you spend more than 183 days in Norway within any 12-month period, or more than 270 days in Norway within any 36-month period. Every day — including partial days — counts. If you hit 183 days in the year you first arrive, you're treated as a resident from your very first day. If those 183 days span two calendar years, residency starts on January 1 of the second year.View Tax Law Source
