Property Tax Reduction Experts

 

Serving Every Corner of Nassau

 

County, New York

​

If you own a home anywhere in Nassau County, chances are you’re paying more than your fair share of property taxes. Year after year, Nassau County’s assessment rolls contain thousands of errors and over-assessments — and the only way to fix them is by filing a formal tax grievance (also called a property tax appeal or certiorari proceeding).

​

At Riverdale Property Tax Relief, we have successfully lowered property taxes for homeowners and businesses in every single municipality in Nassau County — from the North Shore gold coast villages to South Shore waterfront communities, from incorporated villages to unincorporated hamlets. No town, city, or village is too small or too large. We know the local assessment system inside and out.

​

Why Nassau County Homeowners

 

Overpay — and How We Fix It

​

Nassau County’s property tax system is notoriously complex. The county reassesses properties every year, but many assessments are based on outdated data, inaccurate comparable sales, or simple clerical errors.

​

Common reasons we win reductions:

  • Incorrect square footage or lot size in county records

  • Failure to account for structural issues, flood zones, or functional obsolescence

  • Using comparable sales from higher-priced neighborhoods

  • Over-valuing unique properties (waterfront, historic, equestrian, etc.)​

Don’t Wait Another Year Paying Too Much

Every day you delay is another day you’re overpaying. The grievance window closes once per year, and missing the March deadline means you’re stuck with your current assessment for another full tax year.
