Mount Vernon Overview
Mount Vernon Assessment Department
The Mount Vernon Assessment Department handles all property tax records for the city. Commissioner Stephanie Vanderpool leads the office. She was appointed in 2016 as the first African American woman to serve as City Assessor. The department generates more than half of the city's total revenue each year, which shows how central property taxes are to Mount Vernon's budget.
Staff at the department keep track of every parcel in the city. They set the condition, value, and taxable status of each one on a yearly basis. The work includes updating ownership records when deeds transfer, recording new sales, and maintaining the official tax map. The office also processes exemptions and assists property owners through the grievance process when they want to challenge an assessment.
The tentative assessment roll comes out by June 1 each year. Property owners can review it and raise concerns before it becomes final on August 1. If you have questions about a recent assessment, call 914-665-2325.

Westchester County runs a GIS-based property search that covers Mount Vernon. The Westchester County Tax Commission portal lets you look up any parcel by owner name, legal address, or parcel ID. Once you find a property, you can see its assessed value, lot size, and exemption status. The interactive map lets you click on parcels to pull up details, which is handy when you know where a property is but not its exact address.
The 2025 Final Assessment Roll is available online through the city website. Assessment rolls are public records. They show lot size, ownership, assessed value, and any exemptions. The city updates the tax map twice a year to reflect changes in parcels and ownership. If you need to see what a property sold for, Westchester County also keeps transfer records.
Note: For deed and mortgage records, check the Westchester County Clerk's office at 110 Dr. Martin Luther King Jr. Blvd in White Plains.
Mount Vernon Property Tax Exemptions
Several exemption programs can cut your tax bill in Mount Vernon. The STAR program lowers school taxes for owner-occupied homes. Basic STAR is open to all qualifying homeowners. Enhanced STAR gives a larger reduction to seniors 65 and older who meet the income threshold. You apply through the state or directly with the Mount Vernon assessor.
Veterans can get a property tax exemption under RPTL Section 458-a based on their service record. The amount depends on whether you served in a combat zone and if you have a service-connected disability. Senior citizens with limited income may also qualify under RPTL Section 467 for a sliding-scale reduction. Each program has its own forms. The assessment department staff can walk you through the application and deadlines. Grievance forms (RP-524) are available on the city's website for anyone who wants to challenge their assessed value.
