I live in Illinois and work in Iowa, what state return do I file?

ANSWER

The BIDaWIZ Team's Answer:

Since you are an IL resident, you must file an IL tax return; regardless,

of where the income is earned. When you prepare the annual W-4 form,

& the IL equivalent form, confirm that your correct state of residency is

indicated thereon. If Iowa taxes are erroneously withheld, from your pay,

you must file a non-resident Iowa tax return, and claim a 100% refund

of any Iowa taxes that you paid.
