How do I know if I'm a full-year resident of North Dakota?
You are considered a North Dakota resident if you meet either of the following requirements:
- You were a resident of North Dakota for the entire tax year.
- You maintained a permanent place of residence in North Dakota and you spent more than 210 days of the tax year in North Dakota.
So, even if you were not a resident of North Dakota for any part of the tax year, you may still need to file as a full-year resident if you meet the 210-day rule described above. This rule does not apply to part-year residents of North Dakota, full-year nonresidents serving in the U.S. armed forces, or Montana or Minnesota residents who are covered by reciprocity.
