You will have to
file an Illinois nonresident return to recover the erroneous withholdings. On the
nonresident return, you'd
declare earnings of $0 so you can get a full refund for the taxes your employer
withheld.
You should submit Form IL-W-5-NR to
your employer so they stop taking Illinois income taxes and withhold Wisconsin income taxes and avoid the same problem next
year.
To ensure accurate calculations, we strongly recommend preparing your IL nonresident state return before you prepare your WI resident state return..
The first thing you want to do is make sure you've filled out
the Personal Info section correctly:
1. With
your return open, click the first tab, Personal Info.
2. Continue
to the Your
Personal Info Summary screen.
3. Scroll
down to the last section, Other
State Income, and click Edit.
4. At
the Did you make
money in any other states? question, answer Yes (even though you made $0
dollars in that state) and make sure your nonresident
state(s) are selected from the drop-down.
5. Click Continue to return
to the Your
Personal Info Summary screen.
After you finish your federal return, you'll automatically move
to the State
Taxes tab, where you'll see your nonresident state(s)
listed in addition to your resident state.
