NOTE: Tax buyers applying for a refund must provide the original validated receipt and letter of deletion from the County Clerk's Office.

NOTE: In compliance with Cook County Ordinance 07-O-69, if you are a mortgage lender or any business organization that services real estate loans, for example, a title insurance company, you must include along with your refund application and proof of payment, a separate check in the amount of $50 for EACH refund application that you submit to this Office. Please remember to put on the face of the check, and NOT on the check stub, the: (i) PIN; (ii) address of the property; (iii) the tax year for which you are requesting a refund; and, (iv) your company's name, address, telephone number and email address.
