Pro Tip for NYC Tax Commission Appeals
The NYC Tax Commission evaluates properties based on market value as of January 5 (the tax status date). Our Comparative Market Analysis (CMA) provides comparable sales evidence from Bronx neighborhoods that commissioners recognize and respect. Focus on properties with similar characteristics in your immediate area for the strongest appeal.
File Your Application with the NYC Tax Commission
Submit your application through the NYC Tax Commission online portal during the March 1-15 filing window. Online filing is required for all applications.
Critical Filing Window
The NYC Tax Commission accepts applications only from March 1 through March 15 each year. Missing this 15-day window means you cannot appeal your assessment for that tax year. No extensions are granted. File as early as possible to avoid technical issues on the deadline day.
Filing Requirements:
Understanding NYC Property Tax Classes
Bronx properties are classified into four classes: Class 1 (1-3 family homes and condos), Class 2 (4+ unit residential buildings and coops), Class 3 (utility properties), and Class 4 (commercial properties). The Tax Commission process applies to all classes, though Class 1 properties have special assessment caps that limit year-to-year increases.
Attend Your Tax Commission Hearing
Present your case to NYC Tax Commission commissioners at your scheduled hearing, typically held from September through December.
Tax Commission Hearing Process
After filing, you'll receive a hearing notice by mail with your scheduled date and time. Hearings are held at the NYC Tax Commission offices in lower Manhattan. You typically have 5-10 minutes to present your case to a panel of commissioners. Professional, fact-based presentations focusing on comparable sales evidence are most effective.
Hearing Preparation:
Tax Commission Hearing Best Practices
Tax Commission hearings are formal proceedings. Commissioners appreciate clear, concise presentations with strong comparable sales evidence. Avoid emotional arguments and focus on factual data. Practice your presentation beforehand and be ready to answer questions about why your comparable sales are appropriate matches for your Bronx property.
Receive Your Tax Commission Determination
The NYC Tax Commission will mail their determination after reviewing all cases, typically in late fall or early winter.
What to Expect:
Success Timeline and Annual Appeals
Successful Tax Commission appeals typically conclude by January. Your reduction will be reflected on upcoming tax bills. Property owners can file Tax Commission applications annually if they believe their assessment remains excessive. Many Bronx homeowners file every year to maintain fair assessments as market conditions change.
Understanding Bronx Property Tax Classes
New York City uses a four-class property tax system that affects how your assessment is calculated and capped.
Class 1: Residential Properties (1-3 Units and Condos)
Includes single-family homes, 2-3 family homes, and condominiums. Class 1 properties benefit from assessment caps that limit annual increases to 6% and five-year increases to 20%. Most Bronx homeowners fall into this category.
Class 2: Residential Properties (4+ Units and Coops)
Includes apartment buildings with 4 or more units and cooperative apartments. Class 2 properties face higher tax rates but can achieve significant savings through successful Tax Commission appeals.
Class 3: Utility Properties
Includes utility company real property such as power plants and gas distribution facilities. Limited applicability for most Bronx property owners.
Class 4: Commercial and Industrial Properties
Includes office buildings, retail spaces, factories, and most other commercial properties. Class 4 properties can benefit significantly from Tax Commission appeals given the higher effective tax rates.
