Frequently Asked Questions
How do tax grievances work in Nassau County?
In Nassau County, homeowners can file property tax grievances annually, typically from January to early March, to contest assessed values and reduce taxes. The county's Assessment Review Commission (ARC) initially reviews all grievances.
If denied or only partially granted, the homeowner (or their authorized representative) can appeal to a Small Claims Assessment Review (SCAR) in New York State Court. Unlike some states, a failed tax grievance in New York cannot lead to an increased assessed value of your property.
What is the timeline for a tax grievance?
The timeline is lengthy; a full grievance cycle in Nassau can take 18 to 24 months from filing to final resolution. Thus, the awarded reduction is applied retroactively to the tax year in question, so you typically receive savings as a refund or credit.
What does Ownwell do differently?
Ownwell specializes in property tax reduction for homeowners, small businesses, and real estate investors.
To help save you money, Ownwell evaluates your current appraised value and performs a comparative market analysis using our technology-driven platform. We'll then prepare and file evidence on your behalf and attend any hearings with the ARC or SCAR to get a reduction. We're a nationwide service and have more data and years of combined property tax experience than Maidenbaum or any other Nassau firm.
After completing your property tax grievance, we continue to monitor your property's future assessments and will automatically appeal again if your taxes seem unfair.
What is Ownwell’s success rate in Nassau County, NY?
In Nassau County, we typically achieve successful reductions in 85% of our cases, with those reductions resulting in an average savings of $1,538 on property tax bills since joining Ownwell.
Are there specific costs and fee structures I should watch out for?
Ownwell charges 25% of the first-year savings. In contrast, many legacy competitors (such as Maidenbaum) charge 40% to 50% of your savings — see our Nassau comparison page.
Furthermore, unlike Maidenbaum and other traditional companies, Ownwell covers your $30 filing fee if your tax grievance goes to SCAR. You pay absolutely nothing out of pocket, and nothing if we don't successfully reduce your tax burden.
