We are in our first year of full timeing and South Dakota is our residence. SD does not have state income tax so it appears one does not have anything to file for income tax with SD. Is my thinking correct?
Tax software like Turbo-Tax and the others won't let you file a 'state' return if you state is SD, or Texas or Florida or other states without a state income tax.
However, in many cases you will have to file a state income tax return for a state in which you earned money.
If you were employed and earned money in a state with an income tax before going full-time and changing your residence in 2013, you will almost certainly have to file in that state.
If you workcamped in states which have a state income tax, you might have to file in those states also.
I know one fulltimer who had to file four state income tax returns for 2012 - and his home and legal residence are in Texas.
Many years ago, I knew a lady here in Texas who won a lottery scratch off on a trip to some mid-west state. And for the 20 years the scratch off paid out - she had to file a state income tax return for that state for that money.
