Hello,
I'm in the military and my home of record is Indiana. I never did the paperwork to change my HOR. I just realized that I've been filing my state taxes for the wrong state, Deleware, for the last 7-8 years. I was under the assumption once you got a license in state you became a resident. I lived in Delaware from 2013-2017. Then moved to Germany and filled non resident for Deleware from 2017-2021. Do I file an amendment for non resident state return for all those years? What are my options?
