The Illinois Homeowner Exemption Waiver (to remove the exemption) is a document used to waive the homeowner exemption on a property tax bill. This waiver is necessary for those who are no longer eligible for the homeowner exemption due to changes in ownership or occupancy of the property. This document must be filed with the county assessor in order to remove the exemption from the property. There are two types of Illinois Homeowner Exemption Waiver (to remove the exemption): the Standard Waiver and the Senior Exemption Waiver (for seniors over age 65). The Standard Waiver is used to waive the exemptions on a residence that has been owned for fewer than two years, or has been occupied by a new owner. The Senior Exemption Waiver is used to waive the exemptions on a residence owned and occupied by a senior over the age of 65. Both waivers must be signed and filed with the county assessor within 30 days of the change in ownership or occupancy in order to be valid.
