The Illinois Veterans Organization Freeze (IOF) is a program designed to provide tax relief to veteran organizations in the state of Illinois. The program specifically freezes property tax assessments at the rate it was assessed when the veteran organization acquired the property. This freeze applies to veterans organizations that are either eligible for or already receiving tax-exempt status from the state of Illinois. Generally, the following veteran organizations are eligible for the IOF: • Veterans organizations chartered by Congress, • Veterans organizations chartered by the state of Illinois, • Veterans organizations that are members of the American Legion, VFW, or other recognized veterans organizations, • Veterans organizations that are non-profit, and • Veterans organizations that are organized for the mutual benefit of veterans. The IOF program has two types of freezes: a Permanent Freeze and a Temporary Freeze. The Permanent Freeze is applied to property tax assessments that remain frozen as long as the veteran organization owns the property. The Temporary Freeze applies to property tax assessments that are frozen for a period of ten years. After the ten-year period, the tax assessment is no longer frozen and the property is subject to annual property tax assessments.
