What to do

Frequently asked questions

Do I pay Montana income tax if I live in North Dakota?

No. Under the reciprocity agreement you pay only North Dakota. ND residents working in MT exempt from MT tax on wages; file Form NR-2 (Montana Employee's Certificate of Nonresidence).

Do I have to file taxes in both North Dakota and Montana?

Usually you file only one state return (a resident return in North Dakota), though some states still require a nonresident return to get a refund of any wrongly withheld tax.

Will I be taxed twice?

No. Under the reciprocity agreement only North Dakota taxes your wages: about $691 on $100,000.
