Nassau and Suffolk County Homeowners are eligible to challenge their Assessment Value every year through a process known as a Property Tax Grievance.**

A Property Tax Grievance is a formal request to review your property’s Assessment Value. Which is one of the multipliers used to calculate your property taxes.

If your Assessment Value is too high, you may be paying more than your fair share in property taxes.

How the Process Works

Four steps to lower property taxes:

1. Submit Your Authorization: It only takes a few minutes to complete and could save you thousands in property taxes.
   
2. We Build Your Case: A real property tax professional from our Evaluation Department reviews your property multiple times throughout the grievance process to build the strongest case possible.
   
3. We Fight For You: From start to finish we handle everything for you while keeping you informed every step of the way.
   
4. You Save Money: When we secure a reduction, you only pay a portion of the savings we achieve for you, and our team handles the entire process from start to finish, making it simple and stress-free. Best of all, if we don’t secure a reduction, you pay nothing.
   No Reduction, No Fee. Guaranteed!
