Town Assessor

Annual Assessment Filing Period: June 1 – third Tuesday in June

Any person aggrieved by an assessment (e.g., an owner, purchaser, or tenant who is required to pay the real estate taxes pursuant to a lease or written agreement) may file a complaint. The complaint must be filed in the city, town or village in which the property is located. For real property located within the Town of Mamaroneck, that complaint can be filed with the Town Assessor or the Board of Assessment Review.
