New York City assesses over one million properties for tax purposes every year. And every year, thousands of those assessments are wrong — often significantly overvalued, resulting in higher tax bills than legally required.
Understanding NYC Property Tax Assessment
The NYC Department of Finance assesses the value of your property each year. Your tax bill is calculated based on that assessed value multiplied by the applicable tax rate. If your property is overassessed, you are paying more than you should.
Who Should Appeal
Consider appealing if your assessed value increased significantly year over year, comparable properties in your neighborhood are assessed lower, your property has issues that reduce its market value, or you recently purchased your property for less than the assessed value.
Step 1: Review Your Notice of Property Value
The NYC Department of Finance mails a Notice of Property Value each January. Review it carefully. It shows your current assessment and how it compares to prior years.
Step 2: Research Comparable Properties
Use the NYC Department of Finance online property search tool to find similar properties nearby and compare their assessed values. If yours is higher without justification, you have grounds to appeal.
Step 3: File with the Tax Commission
For most property owners, appeals go to the NYC Tax Commission. The deadline to file is typically March 1 for Class 1 properties and March 15 for other property classes.
Step 4: Prepare Your Evidence
Strong appeals include a recent independent appraisal, documentation of comparable sales, evidence of property conditions that reduce value, and income and expense statements for rental properties.
Step 5: Attend Your Hearing
Tax Commission hearings are relatively informal. Present your evidence clearly and professionally. Many property owners hire a tax certiorari attorney who works on contingency.
