The NYC Flip Tax: Your Guide to an Overlooked Co-op Closing Cost

Navigating the New York City real estate market can feel like learning a new language. You have your traditional closing costs, and then there are the fees unique to the city, like the "mansion tax" and transfer taxes. But perhaps the most misunderstood of all is the flip tax.

Despite its name, a flip tax is not a government tax. It’s a fee paid directly to a building’s cooperative (co-op) or, more rarely, a condominium (condo) on the sale of an apartment. While most common in co-ops, some condos have also adopted similar fees, often called "transfer fees" or "capital contributions."

So, what exactly is a flip tax, why does it exist, and how does it affect your bottom line as a buyer or seller? This comprehensive guide breaks down everything you need to know.


What Is a Flip Tax?

A flip tax is a fee charged by a residential building's board to a shareholder (in a co-op) or unit owner (in a condo) when their apartment is sold. Unlike government taxes, which are collected by the city and state, the proceeds from a flip tax go directly into the building’s finances.

The fee is formally known as a “transfer fee” in the building’s governing documents. The term "flip tax" is an informal, colloquial name that originated in the 1970s when many New York City rental buildings were being converted into co-ops. This fee was designed to deter the rapid, speculative buying and selling—or "flipping"—of units, which could destabilize a building's community and finances.

Today, while it still discourages short-term ownership, its primary purpose is more practical: to serve as a vital source of revenue for the building’s operating budget and capital reserve fund.


Why Do Buildings Charge a Flip Tax?

A flip tax provides a reliable, non-intrusive way for a building to generate income without raising monthly maintenance fees or levying special assessments on all residents. This funding is crucial for a building's long-term health and stability, as it can be used for:

  • Capital Improvements: Funding large-scale projects like a new roof, boiler replacement, elevator modernization, or lobby renovation.

  • Building Reserves: Adding to the building’s financial cushion, which can cover unforeseen emergencies or major repairs.

  • Debt Reduction: Paying down existing loans the building may have taken out for previous projects.

By funding these needs through a flip tax, the building can keep monthly maintenance costs lower for all shareholders, making the building more financially appealing to both current and future residents.


Who Pays the Flip Tax: Buyer or Seller?

This is one of the most common points of confusion. In the vast majority of cases in NYC, the seller is responsible for paying the flip tax.

However, it's important to understand that who pays is ultimately a matter of negotiation between the buyer and seller. The fee is a term of the transaction, and the board simply requires that it be paid at closing, regardless of which party provides the funds. While it is customarily the seller, the buyer's purchase contract will specify who is responsible.


How Is a Flip Tax Calculated?

There is no single, standard formula for calculating a flip tax in NYC. Each building’s co-op board sets its own policy, which is outlined in its proprietary lease and by-laws. The method can vary dramatically from one building to the next, even on the same block.

Here are the most common calculation methods:

Common Flip Tax Calculation Methods

Calculation Method

Description & Examples

Percentage of the Gross Sale Price

The most common method. The tax is a percentage of the total sale price of the apartment. This is the easiest to calculate and provides the most predictability. Example: A 2% flip tax on a $1,000,000 sale equals a $20,000 fee.

Percentage of the Seller's Profit

The tax is a percentage of the capital gain the seller makes on the sale (sale price minus their original purchase price). Some buildings allow sellers to also deduct the cost of documented capital improvements from their profit. Example: Selling an apartment for $1,000,000 that was purchased for $600,000 results in a $400,000 profit. A 10% flip tax would be a $40,000 fee.

Fixed Dollar Amount Per Share

The tax is a set dollar amount for each co-op share assigned to the apartment. The number of shares is determined by the building and is generally based on the size and desirability of the unit. Example: A unit with 1,000 shares and a flip tax of $50 per share would incur a $50,000 fee.

Flat Fee

The simplest method. The flip tax is a fixed dollar amount, regardless of the sale price or profit. Example: A building has a flat flip tax of $2,500 on every sale.

Hybrid or Sliding Scale

A combination of methods or a sliding scale based on the length of ownership. For example, a building may charge a 2.5% flip tax for sales within the first three years of ownership, but the rate drops to 2% after three years.

A Special Note on HDFC Co-ops

Housing Development Fund Corporation (HDFC) co-ops are a type of limited-equity cooperative designed to provide affordable housing. To maintain affordability and prevent speculation, HDFC co-ops often have significantly higher flip taxes—sometimes as high as 30% to 40% of the profit. This ensures that the building shares in the gain and can continue to operate and provide affordable housing for future buyers.


How Does a Flip Tax Affect You as a Seller?

As a seller, the flip tax is a significant closing cost that must be factored into your financial planning. While it's an additional expense on top of other seller closing costs (like broker commissions and transfer taxes), it's important to view it as a necessary part of the sales process in many co-op buildings. It can be a major expense, but it also reflects a building with healthy finances, which can be an attractive feature for potential buyers.

Example Scenario: Seller Closing Costs

Let's assume you're selling a co-op in NYC for $1,000,000 with the following costs:

  • Broker Commission: 5% of the sale price = $50,000

  • NYC Real Property Transfer Tax (RPTT): 1.425% of the sale price = $14,250

  • NYS Real Estate Transfer Tax: 0.4% of the sale price = $4,000

  • Flip Tax: 2% of the sale price = $20,000

  • Legal Fees & Misc.: ~$2,000

In this scenario, your total closing costs would be approximately $90,250, with the flip tax representing a significant portion of that total.


How Does a Flip Tax Affect You as a Buyer?

As a buyer, a building's flip tax policy is a key piece of information you should research before making an offer. While you may not be directly responsible for paying the fee, it can be a good indicator of the building's financial health.

A building that collects a flip tax is likely to have a robust capital reserve fund, which means it is less likely to need to raise maintenance fees or issue a special assessment to pay for future projects. This financial stability is a major benefit that can protect your investment and keep your monthly expenses predictable.


Tips & Takeaways

  • Understand the Difference: A flip tax is a private transfer fee paid to the building, not a government tax. Do not confuse it with the NYC and NYS transfer taxes, which are paid to the government.

  • Do Your Due Diligence: Always ask your real estate agent to confirm the building’s flip tax policy, including who pays and how it's calculated. This information is a standard part of the co-op's offering plan and can be provided by the managing agent.

  • Negotiate Wisely: As a seller, factor the flip tax into your listing price and your negotiation strategy. As a buyer, recognize that a building with a flip tax is often a sign of financial stability.

  • Check the Proprietary Lease: The most definitive source of information is the building's proprietary lease or by-laws, which outline the rules for the flip tax.
