The New York State Department of Taxation and Finance reminds property owners — homeowners and businesses — that the deadline to challenge their property assessment is the fourth Tuesday in May in most communities.

That day, May 22 this year, is known as “Grievance Day.”

Tentative assessment rolls, which list the assessed value of each property, are generally made public in the beginning of May. You can access the rolls on your town’s website, or by visiting your local assessor’s office.

If you believe the market value listed on the assessment roll for your property is significantly higher than the price for which you can sell the property, visit Contest your assessment on the Tax Department's website.

Your local Board of Assessment Review will review your case based on the information you provide. When filing for assessment review, you must provide a market-value estimate of your property. You can support that estimate with documentation about the sale of comparable homes or properties in your community.

A recent appraisal can be helpful, but isn’t necessary. The Tax Department’s website also includes information on how to estimate the market value of your home.

Assessment rolls also list the property tax exemptions each property receives. If you applied for an exemption that you’re eligible to receive and it doesn’t appear on the assessment roll, you can use the grievance process to appeal to the local Board of Assessment Review.
