State tax filing

IF you are only in ND on a temporary basis to work, and the  employer is withholding MN taxes, then you say No to working in another state.  The ND-MN reciprocal tax agreement allows you to do so.

BUT

IF you are remaining there for the forseeable future...then you did "move" to ND, and should be paying ND taxes.  As a part-year resident for the year you "move" and then as a full year resident for subsequent years....and register your car, get Driver's lisc, Insurance.....register to vote in ND...etc..etc

As you note...college students with parents in MN remain MN residents...Military people with HOR in MN and their spouses may also be able to claim MN residence even if posted in ND
