Procedures for Challenging Your Property Tax Assessment in New York

Learn the steps you can take to challenge your property tax assessment in New York.

As explained in the companion article, Should You Challenge Your Property Tax Assessment in New York, you may investigate your tax assessment and determine that the local assessor has placed too high a taxable value on your home. If that has happened, your property tax bill will be unfairly high. This article will describe how you may be able to lower that taxable value – and reap big tax savings.

What You Need to Challenge the Taxable Value of Your Home in New York

To successfully challenge the taxable value, you’ll need to establish at least one of the following facts:

  • The tax assessor relied on information that is incorrect or incomplete. For example, the assessor may have assumed that your home contains 2,250 square feet of space when it actually has only 1,750 square feet.
  • The tax assessor set the taxable value of your home that is higher than the taxable values of similar homes in your community.
  • The tax assessor assumed that the current market value of your home is higher than it actually is.

If you’re convinced that any of these facts is true, consider the following strategies for trying to get your taxable value reduced.

Confer With the Tax Assessor

If you have convincing evidence that the assessor has overvalued your home, he or she may agree to change the value. If that happens, you won’t need to pursue an administrative appeal. You can get contact information for your local tax assessor and a variety of other useful information, at the Municipal Profiles section of the New York State Office of Real Property Tax Services. Simply find your county on the map, and search for your city or town; then click on the relevant topic, such as Local Officials Addresses or Tax Rate and Levy Data.

Most assessors are hard-working officials who take pride in their work, and do their best to treat homeowners fairly. It’s best to phone ahead for an appointment with the assessor or an assistant. Before your meeting, make extra copies of your evidence, such as appraiser reports, related to the value of your home. When you meet, assume that the assessor is acting in good faith and is willing to consider your evidence. There’s no need for you to be argumentative or to complain about how property taxes have become burdensome. Just stick to evidence that warrants a lower taxable value for your home.

The assessor may change the taxable value on the spot but, more likely, will need a few days or weeks to look into the issue.

Pursue An Administrative Appeal

If you can’t reach agreement with the assessor, you can appeal the valuation of your home. Here's where to appeal and useful evidence for doing so.

Where to Appeal

Where to appeal depends on where your home is:

  • If you live in New York City, file your appeal with the New York City Tax Commission between January 15 and March 1.
  • In Nassau County, file your appeal with the Assessment Nassau County Review Commission by March 1; for more information, go to the Nassau County Assessor website.
  • Elsewhere in the state, file your appeal with the local Board of Assessment Review, using Form RP-524. The Board hears appeals beginning the fourth Tuesday in May.

Call the assessor’s office for details on what paperwork you need to submit and the deadline for such submissions. There will be a hearing where your evidence will be considered.

Useful Evidence for Your Appeal

In pursuing your appeal, several types of evidence may be useful, including:

  • a recent appraisal of your home
  • a contractor’s report showing repair work needed on your home and how much the work will cost
  • documents showing actual sales prices in your neighborhood near the time you bought your home, and
  • photographs of homes similar to yours, together with a list of their sales prices or taxable values.

At the hearing, you’ll probably have just five or ten minutes to present your case, so be succinct. Bring extra copies of your documentary evidence so that each hearing officer has a copy. Try to include a chart showing comparative sales prices and taxable values. You may want to arrive early so that you observe – and learn from – other people’s hearings.

Consider Asking a Court to Review the Administrative Appeal Decision

If you don’t agree with the decision on your administrative appeal, you can go to court for a further review. In New York City, you must start your court case before October 25. In other New York locations, the deadline for going to court is 30 days after the tax roll is finally completed. You’ll probably need to hire a lawyer to advise or represent you if you plan to go to court. To find an experienced real estate lawyer in New York, check out Nolo’s Lawyer Directory.

There is a simplified procedure, however, if the taxable value of your home doesn’t exceed $450,000; in that case, you may prefer to handle the proceeding yourself.
