Thank you for this response! This is so helpful. I never knew the importance of a W4 form until now. It's my first situation where I moved while maintaining the same job. So no, I never informed my employer, so perhaps that's why the state amounts are referencing about the same number.
I imagine the steps here are to:
1. Inform the employer and get a corrected W2?
2. In the case that the W2 is not sent back in time. It looks like this error will not affect my federal tax returns, but just my state returns. Turbotax is reporting I do not owe any tax to NJ after I filled out the forms correctly, and it looks like I do owe money to NYC. Is there any harm for me filing my return by Apr 15 when I know my W2 form is wrong in line 16?
