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. If you're not sure where your property is officially located, visit How do I know if I live in "The Town"?
The application form and instructions, RP-524 and RP-524-INS, are available from NYS Department of Taxation and Finance. You may complete the complaint form yourself or have your representative or attorney complete it for you.
