Tax Grievance Basics

A property tax grievance is a formal complaint submitted to your country disputing your property assessment value. You actually cannot grieve your taxes, you are only able to grieve your assessment. But in leymans terms lowering your assessment will save you money!

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.
The Assessors office determines your assessment value every year and on January 2nd will make public the assessments.

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, you can 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, 2023 and March 1, 2023.

The Assessment Review Commission may reduce your assessment as appropriate.
The Assessment Review Commission will never increase the assessment.

There are only two possible results of filing a Nassau County, Long Island tax grievance: your assessment will be reduced or it will remain the same. Your assessment cannot be increased as a result of a grievance for that year.

We will only charge you for the savings that we achieve and will not take credit for any property tax exemptions – such as the Basic or Enhanced STAR, Senior or Veteran’s exemptions – that you may have filed on your own. No one will be coming to your home to inspect your property as a result of filing a grievance. There will be no red flags. There will be no chance of backfire.

We can only challenge the assessed value of your property, not the School or General tax rates. Tax rates are a function of the relationship between assessed values and local budgets such as the county, town, school and village. They are set by local organizational entities such as the County Legislature, the town, village or school boards in your neighbourhood.

If the offer is accepted and the reduction is implemented, you will receive tax bills based upon the reduced assessment beginning with the October 2024 School Tax bill and ending with the July 2025 General Tax bill.
If the offer is rejected or no offer is made, I may continue with an appeal filed in Nassau County Supreme Court for a Small Claims Assessment Review in April 2024. I will then present the case for a reduction before a court-appointed hearing officer, who should provide us with a hearing decision within 45 days.
