Exemptions
There will be some circumstances when exemptions will not automatically renew; when a property has been sold, if the property owner owns multiple properties, or if the property is held in trust. It is my understanding that the Cook County Assessor will be sending out a letter or post card to previously qualifying seniors regarding Senior Freeze Exemptions around mid-March. The exemption application window closed April 29, all exemptions must be filed as certificates of error.

Disabled Veteran and Returning Veteran Exemption
A property tax exemption for disabled veterans allows more disabled veteran's greater tax savings. All veterans who are designated as disabled are entitled to property tax savings. Veterans who are 70% or more disabled will be exempt from property tax.
Eligibility rules and tax savings: To qualify for the Disabled Veterans Exemption, a property must be owned and occupied by a disabled veteran or surviving spouse, and the veteran must have a disability that is connected to military service. The law requires that the service-connected disability be certified by the US Department of Veterans Affairs, which determines the extent of a veteran's disability.
The level of reduced property tax is dependent on the percentage of medically certified disability.
