Inconsistent State and County income in W2 | Employer taking too long to fix

Dear Community Members,

 

My W2 has information about two states. I was a part-year resident in both IN and IL. I moved in the middle of the year. My W2 has the following two discrepancies:

  1. IN state income (box 16) and IN county income (box 18) are not the same. Note that I did not live in two different counties in IN. Box 18 is lower than box 16.
  2. Next, box 16 for IN and box 16 for IL do not sum up to be equal to federal wage (box 1). Box 16 for IN + Box 16 for IL is greater than box 1.

I have created a ticket with my employer for more than a month ago to help me resolve this. However, they have not yet provided any solution and are blaming ADP for it.

 

What is the solution for me? What should I do in this case? Do not hesitate to get back to me in case of questions.

 

Thanks,
