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 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?
Ownwell specializes in property tax reduction for homeowners, small businesses, and real estate investors. To help save you money, Ownwell will evaluate your current appraised value and perform a comparative market analysis.
We'll then prepare and file evidence on your behalf and attend any hearings with the ARC or SCAR to get a reduction. After completing your property tax grievance, we'll continue to monitor your property's future assessments and will file a tax grievance again if your taxes seem unfair.
What is Ownwell’s success rate?
Our success rate varies across geographies. We typically achieve successful reductions in 85% of our cases, with those reductions leading to an average savings of $1,538 on their property tax bills since joining Ownwell.
Are there specific costs and fee structures?
Ownwell charges 25% of the first-year savings, but unlike many other companies, we’ll cover your $30 filing fee if your tax grievance goes to SCAR.
