The Receiver of Taxes Does Not Set Your Property Tax Assessment
But Can Help You Lower Your Taxes!
Reassessment
In 2018, the Nassau County Executive ordered the reassessment of every property within the County’s jurisdiction. Your property taxes are based on the value (assessment) of your home; therefore, the County Executive’s reassessment project could significantly impact the amount you pay in property taxes.
Challenge and Lower Your Taxes
ARC filing period has been extended to March 18, 2024
Taxpayers have the right to challenge their property’s assessment every year by filing an application for correction with the Nassau County Assessment Review Commission (ARC) between January 2nd and March 1st. ARC is an independent quasi-judicial body separate from the Department of Assessment. You may file a property assessment grievance online at AROW (Assessment Review On the Web) or in person at the Assessment Review Commission (ARC) located at 240 Old Country Road in Mineola. By filing online, you will get immediate confirmation that your appeal has been received. If you do not have internet access, you may request that an Application for Correction of Assessment be mailed to you by calling ARC at 516-571-3214. Town of North Hempstead residents may also obtain the 2025/2026 grievance application by calling 311 from within the Town or by coming into the Tax Office.
Reassessment has changed the way ARC will evaluate grievance applications. When challenging your assessment, it is important to build the best case for lowering your assessment by providing data on comparable properties. Use ARC’s online residential appeal system (AROW) sales locator tool to view recent sales of similar homes in your neighborhood and file an application to correct your property’s assessment. There is no charge for filing an appeal. You are not required to hire an attorney and property owners may represent themselves. However, if you do not know how to make a case using sales data, it would be advisable to hire a representative. If you hired a representative to challenge a prior assessment, you are free to change representatives or to file on your own behalf. You may also file an appeal with ARC if you applied to the Department of Assessment for an exemption and it was not granted, or if you feel your property’s class designation is incorrect.
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 file a Small Claims Assessment Review (SCAR) petition to seek further review of their assessment.
Incorporated Villages
Incorporated villages within the Town of North 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.
