The Assessor is responsible for reviewing and determining the assessed value of all properties within the Town. All properties are assessed at a median percentage of market  value. This percentage is annually established by the Office or Real Property Services in Newburgh, New York. For residential properties, the median percentage is called the residential assessment ratio (RAR). For all other types of property the equalization rate (ER) is used. The Town of Mamaroneck does not assess at 100% of market value. For the current rates please contact the assessor’s office. The Assessor’s Office also processes applications for the partial exemption or real estate taxes for qualifying residents. Also available are filing requirements for complaints on real property assessments. Below find link to the various categories of exemptions available:
