Property Taxes … True or False?

House On Hill


Facts and fictions abound when it comes to property taxes, but for the general homeowning public, it can be hard to know the difference. This holds particularly true in Nassau County, where any number of rules, regulations and revisions apply, and where details can vary depending on where you live.

“We have School and General taxes,” said Maidenbaum Supervisor John Frascella, “and many homeowners also have Village or City taxes. Taxes upon taxes in this County! There are different tax rates, assessments, municipalities and more. There’s simply too much information for a layperson.”

So we turned to Frascella to help us, and you, differentiate among the facts and the myths and misconceptions that continue to perplex the public.

There Is No Downside to Filing a Grievance
There are only two possible results of filing a Nassau County 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.

If I Received a Reduction in the Past, I Cannot Get Another
If you allow your assessment to remain the same and do not protest, your property taxes will likely increase due to rising School and General tax rates. Even if you received a reduction last year, it is possible tolower your assessment further, as long as sufficient evidence is found.

My Village or City Tax Assessment Cannot Be Challenged
The County and Village have different assessors. Incorporated Villages are not required to follow the Nassau County’s assessment roll. They are entitled to create their own assessments. We can grieve your Village tax assessment if we determine that you have a meritorious case for a reduction. However, the Village filing deadlines are different from the County.

It Doesn’t Matter When I File a Grievance
Nassau County’s deadline to file a property tax grievance is approximately 18 months in advance of the tax year being challenged, barring any extensions. For example, the deadline to file a 2023/2024 tax grievance is March 1, 2022.


If My Grievance Is Successful, My Reduced Taxes Start Immediately
If the offer is accepted and the reduction is implemented, you will receive tax bills based upon the reduced assessment beginning with the October 2023 School Tax bill and ending with the July 2024 General Tax bill.

It Ain’t Over Till It’s Over
It the offer is rejected, or no offer is made, the case may continue with an appeal filed in Nassau County Supreme Court for a Small Claims Assessment Review in April 2023. We 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.
