Nassau County, NOT the Town of Hempstead, sets your home's assessment, which is the basis of your property taxes. The Department of Assessment estimates the market value of your property and then applies a fractional level of assessment, a percentage of market value at which homes are assessed.
If you feel that your property's tax assessment is out of line (too high) compared to neighboring homes with similar characteristics, exercise your right to challenge it. Remember, there is no charge for doing so, and your assessment can only be lowered or remain the same as a result of a challenge-it cannot be raised.
Nassau County utilizes a four-year cyclical assessment valuation system believed by county officials to offer greater stability and predictability for property owners. Unless physical changes are made to your property or you receive an assessment reduction resulting from a challenge, your assessed value will not change within the cyclical period. Under this valuation system, assessment reductions that are the result of challenges will carry forward into successive years. Property owners may still file an assessment challenge each year.
Residents should receive their home's assessed value from Nassau County in early January 2015. If you do not receive this notification, you may view it online on the Nassau County Department of Assessment's Land Records Viewer (enter your parcel number or propery address and click on "View Correspondence") or call the Assessment Department at (516) 571-1500. The Tentative Assessed Value will be used in determining your 2016-17 school taxes and 2017 general taxes.

Incorporated villages within the Town of Hempstead have the right to utilize their own assessments for village tax purposes, or they may choose to utilize the county's assessment roll as a basis for their assessments. If you live in an incorporated village, you must file separately to challenge your village assessment. Contact your village assessor for information on how to challenge that assessment.
Small Claims Assessment Review
The Assessment Review Commission is responsible for reviewing assessed valuations and making decisions on grievances during this period. Owners who are not satisfied with the Assessment Review Commission's decision have the option to go to Small Claims Court to seek further review of their assessment.
