What can I do to fix this? I live in Wisconsin and I work in IL, i accidentally filled out the wrong forms and have been having IL taxes be pulled from my paycheck.

My work has found a way to fix this for 2024 and the upcoming 2025 (luckily I haven't filed yet). But now how would I be able to get the re-emburstment from 2023? would I call the IRS about this? Anything helps, thank you.

Illinois has the money so you will have to get it back from Illinois.

This involves filing a non-resident tax return for Illinois where you will enter your W2 but tell the system that you did not live in Illinois.  You will qualify for a full refund of your taxes paid to Illinois because of their reciprocity agreement with Wisconsin.

Then AFTER you have done your non-resident return for Illinois, you will do your resident return for Wisconsin.  You're going to owe Wisconsin a bunch of money - probably including some penalties - although with any luck what you owe will be less than the refund you're going to get from Illinois.
