I worked in Indiana until early December 2017 and moved to another state near the end of December 2017. I didn't get my last paycheck from that Indiana job until January 2018. So I have a 2018 W-2 for that job... On the IN tax forms for partial /non-residents, you have to list the county code where you worked as of 1/1/18. In my case, do I need to constructively consider myself to have been working in an Indiana county at 1/1/18, even though I lived in a new state at that time?
