Homeowner's exemption
The Homeowner Exemption is available to owners of single-family homes, condominiums, cooperatives and apartment buildings of six units or less. The property must have been occupied by its current or previous owner as his or her principle residence on January 1st of the tax year for which the exemption is granted. Homeowner Exemptions are automatically applied only if you received one the prior year. The exemption will be applied on your 2nd installment of your property tax bill. This exemption reduces the home’s Equalized Assessed Value (EAV) of $10,000.
Senior citizen exemption
To be eligible for the Senior Exemption, which will reduce your home’s equalized, assessed value by $8,000, you must meet the following eligibility requirements:
- You or your spouse are 65 years of age or older during the tax
year for which you are applying for the exemption, - As of January 1st of the tax year, you must either own or have a lease or contract making you responsible for the property tax,
- As of January 1st of the tax year, the property must be your principal residence.
Senior Citizens receiving a Senior Citizen Exemption automatically receive a Homeowners Exemption and do not have to apply separately. Homeowners who received the Senior Citizen Exemption the prior year do not need to apply every year for this exemption.
Senior freeze exemption
This exemption freezes the Equalized Assessed Value (EAV) of your home. To qualify for this exemption you must meet the following eligibility requirements:
- You or your spouse are 65 years of age or older during the tax year.
- The property must be your principle residence during the tax year (e.g. January 1, 2021 to January 1, 2022) of the assessment freeze,
- Your total gross household income did not exceed $65,000 the prior year for which you are requesting the assessment freeze. Please provide income tax statements.
You must file each year in order to continue to receive the Senior Freeze Exemption. In addition, the above requirements must be met each year to receive the freeze.

leasehold interest of a single-family residence - Occupy the property as the principle residence on January 1

Disabled veterans' exemption
The amount of the exemption each year depends on the percentage of the disabled veteran’s service-connected disability as certified by U.S. Department of Veteran Affairs. A disabled veteran at least 70% disabled will be completely exempt from property taxes. A disabled veteran with at least a 50% to 69% service-connected disability will receive an annual $5,000 reduction in EAV. A veteran with a 30% to 49% service-connected disability will receive an annual $2,500 reduction in EAV.
