Homemaker with different tax domicile than husband
We live abroad. My husband works for the US government, and I have no income. My husband files a joint federal tax return and a non-resident state tax return for the state he is from.
I consider myself a resident in another state (I still vote there, have a drivers license and family still there, and have never lived in another state), but I have not filed tax returns since living abroad because I had no income. Now in trying to get in-state tuition for our son in my state, they want to see my state tax returns. I have backfiled the last 4 years recently, but I am wondering if I even HAVE to file a state return since, I believe, I do not HAVE to file a federal return because I have no income. Am I wrong?
Thanks
