Low-Income Senior Citizen’s Assessment Freeze

Low-Income Senior Citizen’s Assessment Freeze (LISCAFE)


The Senior Freeze provides seniors with limited income protection against real estate tax increases due to rising property values. It is not a tax freeze or a tax reduction and does not protect against increased taxes due to tax rate increases. This exemption provides for a base-year frozen assessment, and it will potentially provide increased savings each year a senior is eligible. The base assessment used in the Senior Citizens Assessment Freeze Homestead Exemption initially equals the assessed value from the prior year tax calculation. In subsequent years, if the new assessed value is lower than the original base value, the lower value becomes the new base amount.

The County’s annual Senior Freeze mailing will not include the PTAX-340 Assessment Freeze application. The County made a decision to have applicants file the annual renewal application online. The County requires proof of income including US 1040 Tax Returns including all schedules (if applicable). If you do not file taxes, you are required to bring proof of income, e.g. Most current Social Security Benefit Statement.

The deadline to renew the Senior Citizen Assessment Freeze is October 31, 2023.

Instructions to file online are available here.

If you are unable to file online, call our office at 847-381-1120 to schedule an appointment.

To Qualify:

To qualify, applicants must:
