Welcome to the Assessor's Office Homepage
The Assessor's mission is to provide fair and equitable valuations to all real property (residential, vacant land, commercial, & industrial) for the purpose of property taxation for Town, County, and school property taxes. This includes, but not limited to, the valuation of all real property, the collection of property inventory, maintenance of ownership information, and implementation of all whole and partial property tax exemptions. For a more detailed description on the roll of the assessor, please feel free to review the following document:

PARTIAL TAX EXEMPTIONS
The partial property tax exemptions that a taxpayer may be eligible for are as follows:
Non profit, and
STAR (School TAx Relief).
All exemption applications MUST be filed in the assessment department at Greenburgh Town Hall no later than May 1. You can download the most common of these exemption forms by clicking on the "Documents & Forms" section of this page.
HOW WE ARRIVE AT YOUR ASSESSMENT
As of June 2016, the Unincorporated Town of Greenburgh, as well as the Villages of Irvington and Ardsley will be assessed at 100%. This means that the assessment should match current market value.
The Town assesses all real property at a percentage of market value. The percentage is known as an equalization rate (ER). These rates are established by the NYS Office of real Property Services (http://www.orps.state.ny.us/) annually. This rate and ratio changed annually based on real estate market trends. Most important is their use to equalize the assessment into full market value prior to 2016. Example of both shown below:
Prior Assessed Value Rate Value
16,500 / 3.09% (EQ) = $533,980
2016 Assessed Value Rate Value
533,980 / 100% = $533,980
Please Note: For the Villages of Tarrytown, Dobbs Ferry, Hastings, and Elmsford, the Village portion of their taxes will be based on the prior method of assessing (a percentage of market value). They will still use the ratio based system to determine value.
The Assessor also assists in the defense of litigation regarding property taxes.
