With programs like property tax abatements and exemptions available to qualifying homeowners, it’s possible to alleviate some of the financial burden—if you know where to start.

1. How Property Taxes Work in NYC

Property taxes in NYC are based on the assessed value of the property, calculated annually by the NYC Department of Finance. The city categorizes properties into four tax classes, each with distinct characteristics and tax rates. While there are more than two classes, this guide focuses on the ones most relevant to residential property buyers:

  • Class 1: Includes one- to three-family homes, small residential properties, and some small mixed-use properties.

  • Class 2: Includes co-ops, condos, and larger residential buildings with more than three units.

Condo owners pay property taxes directly to the city, while co-op shareholders pay property taxes indirectly through their monthly maintenance fees. The assessed value and tax rate are determined by the property's tax class, which depends on its use and size. Market conditions and location influence market value—a property’s estimated selling price under normal conditions—but assessed value is typically a fraction of market value.

2. Key Property Tax Abatement Programs

NYC offers several property tax abatements to reduce costs for qualifying owners. Here are the most common programs:

  • Co-op and Condo Property Tax Abatement: This program provides tax relief to owner-occupied residential co-ops and condos, reducing property taxes by 17.5% to 28.1%, depending on the property's assessed value. To qualify: The property must be the owner's primary residence. Units owned by investors or used as second homes are not eligible.

  • 421a (Affordable New York Housing Program): This program incentivizes new residential construction by providing a temporary reduction in property taxes for qualifying developments. Buyers of 421a properties benefit from significantly reduced property taxes for 10 to 25 years, depending on the project.

  • J-51 Tax Abatement and Exemption: Designed to encourage building renovations, this program offers both an exemption from increased assessed value due to improvements and a reduction in current property taxes. It applies to certain residential conversions and renovations.

  • Green Roof Tax Abatement: Property owners who install green roofs can qualify for a one-time property tax abatement of $4.50 per square foot of green roof space, up to $100,000.

  • STAR (School Tax Relief) Program: The STAR program is a statewide tax relief program for primary residence homeowners in New York, including condos and co-ops. It reduces the portion of property taxes allocated to school districts: Basic STAR for homeowners with annual incomes up to $250,000 and Enhanced STAR for senior citizens (65+) with annual incomes below $93,200.

3. Closing Costs: Transfer Taxes, Flip Taxes, and Mansion Tax

In addition to property taxes, buyers and sellers must account for various closing costs that can significantly impact the final financials of a transaction. These include transfer taxes, flip taxes, and the Mansion Tax. For more information on closing costs visit: Understanding NYC Closing Costs for Homebuyers.

  • NYC and NY State Transfer Taxes: NYC Transfer Tax: 1% for transactions under $500,000; 1.425% for transactions of $500,000 or more. NY State Transfer Tax: 0.4% of the sale price for most transactions. These taxes are typically paid by the seller, although in competitive markets, buyers may negotiate to cover some or all of the cost.

  • Mansion Tax: The Mansion Tax applies to all residential purchases in New York State with a sale price of $1 million or more. The tax rate starts at 1% for properties priced at $1 million and increases incrementally for higher-priced properties, up to 3.9% for properties over $25 million. The Mansion Tax is typically paid by the buyer and should be factored into the total cost of purchasing a property in NYC.

  • Flip Taxes: While not levied by the state, flip taxes, also known as transfer fees, are unique to co-ops. Charged by the co-op board when a unit is sold, flip taxes typically range from 1% to 3% of the sale price. Policies vary by building, and while these fees are usually paid by the seller, it’s important to confirm this with the co-op board before listing your unit.

4. Comparing Property Taxes Between Condos and Co-ops

One of the key differences between condos and co-ops lies in how property taxes are paid:

  • Condos: Owners pay property taxes directly to the city.

  • Co-ops: Property taxes are included in the monthly maintenance fees, along with other building expenses.

Co-op maintenance fees are often higher because they include shared costs like the building’s mortgage, property taxes, and operational expenses. Condo common charges typically exclude property taxes, making them appear lower at first glance.

5. How Abatements Impact Costs

Tax abatements can significantly reduce monthly property taxes, but they are often temporary. For example, the 421a abatement gradually phases out over time, leading to an increase in property taxes. Buyers should carefully review the abatement schedule for any property to understand future costs. Your real estate agent can help analyze these details and ensure you’re making informed decisions about a property’s long-term affordability.

6. Evaluating Tax Implications Before Buying

Before making a purchase, review the building’s financials and tax records to understand how taxes and abatements will affect your costs. Start by reviewing the current property taxes and any abatements and ask about the expiration of abatements like 421a or J-51. The seller’s agent should be prepared with this information and your real estate agent can guide you through these considerations to ensure a well-informed decision.

7. The Role of Your Real Estate Agent

Navigating NYC property taxes, abatements, and closing costs can be overwhelming, but a knowledgeable real estate agent simplifies the process. From identifying properties with favorable abatements to evaluating tax implications and long-term costs, an agent ensures you make informed decisions. They’ll also guide you through reviewing building financials, comparing condos and co-ops, and understanding potential assessments.
