I lived in State1 for the first 10 months of 2012, and then State2 for the remainder of the year. I've already e-filed my federal return and my state return for State1. However, my tax software wouldn't let me e-file my state return for State2, so I'm filing it via mail.
I'm sending my W-2 form from my job in State2. Do I also need to include my W-2 form from my other job in State1?
