Nassau Tax Grievance – Deadline March 3rd, 2025

Nassau County Tax Grievance

Nassau County Tax Grievance

Did you know that you can actually reduce your property’s tax bill if you appeal the value assigned to your property by the taxman? In fact, it’s the estimated value that is used for the purpose of calculating your taxes. If you want to reduce your taxes, the best way is to prove your property is worth less than its estimated value.

If you think you’ve been overassessed, you have a right to protest the assessment – which could mean tax dollars in your pocket.  Let’s face it, in this economy, every dollar counts!

“Nassau County will not voluntarily reduce your assessed value”

The 2024 Tax Grievance season is here and it is setting up to be a big one!  This is mainly due to another dismal year in the yet-to-recover Nassau County housing market.  A bad thing if you are trying to sell, but a great opportunity if you are thinking about grieving your taxes!

Get your property taxes lowered!  Don’t miss Nassau County’s deadline!

Legislator David Denenberg of Merrick (Nassau County) told the following to Newsday;

 “We’ve gotten to the point where the assessments make no sense. The reductions make no sense. The effect on your taxes makes no sense. And the only thing that makes sense is to challenge your assessment.” We believe all Nassau County residents should heed the legislator’s call to action and challenge your assessment.

What is Property Tax Grievance?

Property tax grievance is a formal complaint filed against a town’s assessed value on a particular parcel of property based upon comparable sales. The town places a value on every property. ie – $600,000 – if we can prove your home is worth less than that value, we will accept your grievance. If there are sales in your area that are equal to and above that value, we will send you a letter stating that, in our opinion, you have no case. If a neighbor has a similar home and has lower property taxes, it may mean that they are under-assessed; it is not a basis for accepting your case. The easiest cases to win are those on homes that have been purchased within the last year or homes that are currently for sale. To help entice potential buyers we can supply a letter stating an estimated reduction for homes that are for sale.

When you appeal your property taxes, you are contesting that the property value your taxes are based off is too high, and does not reflect your current market.

A case will need to be presented before them to indicate a lower value for your home than what the department of Assessment has on file. If an agreement cannot be reached with ARC, your case can further be appealed to the Small Claims Assessment Review (SCAR) where it will be heard before a judge.

At Heller and Consultants, we oversee the entire process to make sure that your value is fair and accurate compared to market around you.

Appealing Your Property Tax Bill

Did you know that you can actually reduce your property’s tax bill if you appeal the value assigned to your property by the taxman? In fact, it’s the estimated value that is used for the purpose of calculating your taxes. If you want to reduce your taxes, the best way is to prove your property is worth less than its estimated value. Doing so is easy by researching online or calling your realtor. If in your research you discover that you’re right about this, then the process for appealing can take up to 18-24 months to finalize.

Read your assessment letter

Nassau & Suffolk Counties regularly estimate the real estate they tax. This means that when they receive your estimation, it’s going to contain info regarding your property (such as legal description and lot size), but also the estimated value of your land and property. To calculate your property tax, the local government will multiply your property’s assessed value by the local tax rate (values vary from town to town). However, if you think that your home’s value is a lot higher than its actual value, you should dispute it right away.
