Couldn't have been easier. I just gave them my address and they took it from there. No filing appeals or spending hours to prepare for a hearing to defend my value. Ownwell does it all, no doubt better than I could have done myself. Saved $1500 on my property taxes. Highly recommend.

The Ownwell team is amazing. The process is all online. Their system is easy to use and they know local tax codes and authorities and they know how to work with appraisal districts to fairly represent homeowners. They were able to successfully get a SIGNIFICANT reduction in property taxes for us.

Ownwell was a very easy process. I uploaded my documents and they took care of everything. As a first time homeowner I had no idea how to fight my property taxes.

Ownwell did a great job and ended up getting my property taxes reduced. Their website was very helpful as it provides updates to the status of your case so you always know where you are in the process. I would definitely recommend them.

Great service. Once they took my property tax appeal they handled everything and saved me $.

Ownwell was great and FAST! It was so easy to contact them and they are quick to respond. Definitely referring them to family and friends

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?

In Nassau County, we typically achieve successful reductions in 93% of our cases, with those reductions resulting in an average savings of $1,462 on property tax bills since joining Ownwell.

Are there specific costs and fee structures?

Ownwell charges 25% of the first-year savings. And unlike many other companies, we’ll cover your $30 filing fee if your tax grievance goes to SCAR.
