A home exemption can reduce the taxable value of a home by $120,000 for homeowners who qualify. This amount increases to $160,000 if the homeowner is 65 years or older. As a service to you, let me remind those who qualify to claim their home-owners exemption by the Sep. 30 deadline. I can also provide you with the Parcel ID (Tax Map Key) needed to file your exemption. Doing so helps you avoid paying a higher property tax rate next year.
