Taxes deducted for the wrong State
I live in Virginia and I started a new job in DC. After my second paycheck (since I never got a first one) I noticed that my employer was witholding taxes for DC instead of Virginia. I contacted them and asked them to change it and fix the problem retroactively since I did not want to file for DC (I am already filing for VA, MD and IA). They told me there was nothing they could do (even when it was their mistake) and that now I had no choice but to file DC too. I believe that to be incorrect. They could have fixed the problem before Dec 30. Am I right? Where can I find information regarding this? Thanks.
