Texas has no state income tax. Illinois has an income tax of 4.95%. Around $2.5K was incorrectly taken from my bonus and subsequent paychecks and allotted to the state of Illinois. How do I reclaim that amount since I have lived and worked in Texas the entire time I've been with this company? Side note -- they corrected my coding about two months into the job, and now I am getting the correct withholding per my Texas residency.
