My employer incorrectly withheld IL state tax when I lived in WA, how to claim it back?
I moved from Illinois (where I grew up) to Washington State to start a new job there. However, it was my fault that I left my parents' address in Illinois in my employee profile of the new employer, because I thought that would be like my permanent address despite not living there.
Now in my first paycheck, my employer withheld IL state taxes. I believe next year by filing Illinois Schedule NR, I can get those incorrectly withheld state tax back. But should I ask the employer to fix my W2 too? Because they did withheld IL state taxes for one pay period. Next year am I going to receive separate W2 for IL and WA?
