How to Appeal Your Assessment
If you pay taxes on property in Nassau County, you have the right to appeal the property’s annual assessment. The Assessment Review Commission - ARC - will review your application.
There is a new assessment for each year. The time to appeal a new assessment ends before the taxes based on that assessment are billed. If you disagree with the most recent assessment, appeal it, even if you are awaiting determination of an appeal you filed last year.
If you want ARC to review your property’s assessment, appeal between January 2, 2024, and March 1, 2024.
- There is no fee to file with ARC.
- The application requires only basic information about your property. You can file online.
- You are not required to use an attorney. If you hired a representative to challenge a prior assessment, you are free to change representatives or file for yourself for review of the new assessment.
- The Assessment Review Commission may reduce your assessment as appropriate.
- The Assessment Review Commission will never increase the assessment.
- You should decide whether to appeal the new assessment by comparing the Department of Assessment’s adjusted market value with your own estimate of your property’s current market value.
- The Assessment Review Commission may also correct your tax class and review your appeal if you were denied an exemption.
Do not sign duplicate authorizations. Many grievance services seek an authorization in advance of the filing period. If you decide to represent yourself, do not sign an authorization for a grievance service or other representative. If you decide to hire a representative, do not sign more than one authorization. Unresolved duplicate applications will be denied.
You may not appeal for yourself this year if you have signed an authorization for a representative to file for you after September 1, 2023, or if you own a condominium where the board of managers files for you.
Assessment Review on the Web
All Attorneys filing on any property, where you are not the owner, must be registered with ARC as a representative.
Between January 2, 2024, and March 1, 2024, you may appeal online. You may file an online appeal for any type of property, including commercial property, and any type of claim, including errors in your property’s tax class or exemptions.
If you believe your property value is too high ARC encourages you to file through AROW.
If you file through AROW for yourself, you may check your appeal’s status on-line at any time. You may also look up the status of appeals for past tax years.
