Low-Income Senior Citizen's Assessment Freeze


The Senior Freeze provides limited-income seniors with 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. Because this exemption provides for a base year frozen assessment, 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 their original base value, the new lower value becomes the new base amount.


To qualify, applicants must:

  • Be 65 years of age or older
  • Have owned and occupied the home as their principal residence on Jan. 1 of the past two years
  • Have a total household income of $65,000 or less

Properties Held in Trust:

When you are applying for a new exemption and the property is held in trust, we must verify that the applicant is a current living beneficiary of that trust. The exemptions cannot be applied without this verification. Please include a copy of that part of the actual trust agreement which states that the applicant is a beneficiary. This can usually be found on the first few pages of the trust document. Should you have any questions, please feel free to contact us directly at 847-377-2100.
