How do I get a refund if I am granted innocent spouse relief?

If you are due a refund, Form IL-8857 serves as your claim for refund of any overpayment due you as a result of innocent spouse relief. You do not have to file any other forms to request a refund. There is no time limit for making an innocent spouse claim. However, we will only issue a refund for a tax year if we receive your Form IL-8857 within three years after the extended due date of your original Form IL-1040, three years after the date you filed your original Form IL-1040, or one year after you paid the Illinois tax, whichever is latest. For more information, see Publication 125, Injured and Innocent Spouse Relief.

If you have additional inquiries, you may submit them to the Questions, Comments, or Request form.
