The Online Assessment Data page is the starting point for Westchester County property tax records. From here you can access assessment rolls for every municipality in the county. Search by tax roll, parcel number, owner name, address, or taxable value. The data covers all six cities and every town and village. Each listing shows assessed value, exemptions, and tax class.

Westchester's Municipal Tax Parcel Viewer puts property tax data on an interactive map. Click any parcel to see its details. The GIS system shows boundaries, lot dimensions, and tax map section numbers. You can zoom in to a street level or zoom out to see whole neighborhoods. This tool works well for comparing nearby properties or figuring out which municipality a parcel falls in.

In Westchester County, each city and town maintains its own assessment roll. That means you may need to check the local website for your specific municipality. The county's online data page links to many of these local systems. For example, White Plains uses a MunisSelfService portal where you can search by address, name, or parcel ID. Yonkers, New Rochelle, and Mount Vernon each have their own lookup tools as well.

The County Clerk's Land Records division stores deeds, mortgages, and other recorded documents. You can search these records online through the Clerk's portal. The office at (914) 995-3080 can help with certified copies and questions about recorded instruments. These records fill in the ownership history that the assessment roll does not always show.

Property Tax Assessments in Westchester County

Assessments in Westchester County work at the municipal level. Each city, town, and village has an assessor who sets property values. The county Tax Commission coordinates between these local offices and the state. They handle questions about county tax rates, exemptions, and how RPTL applies across all 48 municipalities. Some towns assess at full market value. Others use a percentage. The equalization rate tells you how your town compares.

Westchester property values are among the highest in New York. A home in Scarsdale or Bronxville can be assessed in the millions. That makes the grievance process critical for homeowners who feel their value is too high. The first step is always to contact your local assessor. Bring recent sales data for similar homes in your area. If the informal route fails, file Form RP-524 with the Board of Assessment Review by the fourth Tuesday in May.

Small Claims Assessment Review is the next option if the board does not lower your value. File Form RPTL-730 within 30 days of the July 1 final roll. The filing fee depends on your assessed value. For high-value Westchester properties, some owners choose the full Article 7 court proceeding instead. That route costs more but allows for a broader legal argument. Talk to a tax attorney before deciding which path fits your case.

The Tax Commission also publishes historical tax rate data and residential assessment ratios. These numbers help you see trends over time. If your town just did a reassessment, values may have shifted in ways that affect your tax bill even if the rate did not change. The commission posts county property tax payment dates as well, so you know when each installment is due.

Westchester County Tax Payment and Collection

Property taxes in Westchester are paid to local municipalities, not the county. Each city and town sets its own due dates and payment methods. County taxes are billed separately and usually due in the spring. School taxes go out in the fall. The exact dates depend on where you live since each of the 48 municipalities runs its own collection process.

Most Westchester towns and cities accept online payments through their websites. Some use third-party processors that charge a convenience fee for credit cards. Check your local municipality's website for the exact options. In-person payments are taken at city or town hall during business hours. Many offices have a drop box for after-hours use. If you own property in more than one municipality, you will get separate bills from each one.

Under RPTL Section 922, the failure to mail or receive a tax bill does not affect the validity of the tax or any interest charges. This matters in Westchester where tax bills can be substantial. A missed payment on a high-value property means a large penalty. Stay on top of your due dates, and call your local tax office if a bill does not show up on time.
