Welcome to AROW, Assessment Review on the Web
The AROW server will be down for maintenance from 05/08/2021 - 05/09/2021 from 11:00 PM to 03:00 AM.
At the request of the Nassau County Executive Laura Curran, ARC will be granting a 60 day grace period extending our 22-23 Grievance Filing Period to April 30, 2021
The Assessment Review Commission - ARC - acts on appeals of county property assessments. ARC's services for homeowners, commercial taxpayers and tax practitioners are available online. You are not required to have a lawyer represent you. You may file your own appeal.
You may appeal your property's assessment from January 4, 2021 at 9 am (after the NC Assessor publishes the tentative roll) to March 1, 2021.
Public information, registration, appeal tracking and the residential sale locator are available all year. Click the link below for "Do you have a good case for filing an appeal?" You will be prompted to enter an address or parcel number for your property. When you reach the AROW Property Search Results click the link for tips on how to use AROW. You can search residential sales, file an appeal
(beginning January 4, 2021 at 9 am)
or look up information about pending or past appeals.
