Co‑Op Flip Taxes on the Upper West Side Explained

Co‑Op Flip Taxes on the Upper West Side Explained

  • 11/21/25

Are you pricing or bidding on a co-op on the Upper West Side and wondering how a flip tax will change the math? You are not alone. Flip taxes are common in UWS co-ops and can shift net proceeds for sellers and total cost for buyers. In this guide, you will learn what a flip tax is, the most common structures on the UWS, who typically pays, and simple ways to model the impact before you list or make an offer. Let’s dive in.

What a flip tax is

A flip tax is a charge collected by a co-operative corporation when shares transfer at resale. It helps fund reserves, operating expenses, or mortgage reduction. It is not a government tax. It is an internal building charge authorized by the co-op’s governing documents.

The legal authority to collect a flip tax must be in the co-op’s certificate of incorporation, bylaws, proprietary lease, or offering plan. If there is no flip-tax provision, the co-op cannot collect one unless shareholders adopt it according to the amendment process. Boards enforce flip taxes as written and collect them at closing, often through a payoff letter prepared by the co-op’s attorney.

Common UWS flip-tax structures

Practices vary from building to building, especially across prewar co-ops. Verify the exact formula before you price or bid.

Percent of sale price

  • Formula: flip tax = sale price × flip rate.
  • Many buildings use low single-digit percentages, sometimes tiered or capped.

Per-share flat charge

  • Formula: flip tax = per-share amount × the unit’s allocated shares.
  • Older co-ops often quote flip taxes as dollars per share.

Percentage of profit

  • Formula: flip tax = flip rate × net profit.
  • Net profit is typically sale price minus the seller’s original cost plus allowable selling costs. This method requires documentation and extra reconciliation.

Fixed or hybrid structures

  • Some buildings set a flat dollar fee per transfer.
  • Hybrids are common, such as a percent of sale capped at a maximum amount, or per-share charges with a cap.

Timing at closing

  • The flip tax is usually collected at closing. The co-op’s attorney issues a payoff or waiver letter and closing counsel includes it on the settlement statement.

Who usually pays

Governing documents control who is responsible. In practice you will see several patterns:

  • Seller pays. This is very common and reduces seller net proceeds.
  • Buyer pays. Less common, but used in some buildings or negotiated deals.
  • Split payment. Parties sometimes agree to share the cost, subject to board rules.
  • Waivers or reductions. Boards can waive or reduce the flip tax in specific situations, but only as allowed by the co-op’s rules.

When you plan pricing or an offer, confirm the building’s rule and reflect it in the contract and closing statement.

How flip taxes change your bottom line

For sellers, a flip tax directly reduces cash at closing if the seller pays. It can also influence list price strategy and concessions. For buyers, a buyer-paid flip tax increases total cash needed and may affect loan-to-value planning.

Seller net proceeds formula

Net proceeds to seller, before income tax, typically equals:

  • sale price
  • minus flip tax (per the building’s formula)
  • minus real estate commission
  • minus seller closing costs, such as attorney fees, move-out fees, and transfer-related fees if applicable
  • minus outstanding mortgage and other liens
  • minus any seller credits or concessions

If the buyer pays the flip tax, remove it from the seller’s side, but account for its effect on negotiations and pricing.

Flip-tax calculations by structure

  • Percent of sale: flip tax = sale price × flip rate.
  • Per-share: flip tax = per-share amount × unit shares.
  • Profit-based: flip tax = flip rate × (sale price − seller basis − allowable costs).
  • Hybrid or capped: follow the building’s written formula.

Example scenarios

Assumptions are for illustration only. Always verify your building’s formula.

  • Example A, percent flip tax, seller pays:

    • Sale price 1,200,000; flip rate 2 percent; commission 5 percent; seller closing costs 5,000; mortgage payoff 300,000.
    • Flip tax = 24,000. Commission = 60,000. Approximate net proceeds = 1,200,000 − 24,000 − 60,000 − 5,000 − 300,000 = 811,000.
  • Example B, per-share flip tax, seller pays:

    • Sale price 750,000; shares 1,500; per-share charge 20.
    • Flip tax = 30,000.
  • Example C, profit-based flip tax:

    • Sale price 900,000; seller basis and improvements 600,000; flip rate 25 percent of profit.
    • Profit = 300,000. Flip tax = 75,000.

Quick net-proceeds model

Use this as a starting checklist for your co-op. Replace the example values with your numbers.

Item Your entry Example
Sale price 1,200,000
Flip-tax method 2 percent of sale
Flip-tax amount 24,000
Commission percent 5 percent
Commission amount 60,000
Estimated seller closing costs 5,000
Mortgage payoff 300,000
Estimated net proceeds 811,000

Note: Always include a step to verify the flip-tax formula in the proprietary lease, bylaws, or an attorney payoff letter.

Due diligence for UWS sellers and buyers

Get clarity early to avoid surprises during board review or at the closing table.

  • Request the proprietary lease, bylaws, certificate of incorporation, and any amendments that mention transfer fees or flip taxes.
  • Ask the managing agent or co-op counsel for a written flip-tax estimate or payoff letter tied to your price.
  • Confirm who pays and any caps, tiers, or exceptions.
  • For profit-based formulas, gather purchase closing statements and records of capital improvements now.
  • Make sure your attorney aligns the flip-tax treatment with lender requirements and the settlement statement.

Negotiation and pricing strategy on the UWS

A flip tax affects how you structure price and concessions.

  • Who pays. Negotiate buyer, seller, or split, subject to the co-op’s rules. Many sellers plan to pay and price accordingly.
  • Asking price. Some sellers adjust their ask to offset a seller-paid flip tax. Weigh competitiveness and appraisal sensitivity before increasing list price.
  • Waivers and credits. Boards can sometimes waive or reduce fees for inter-family transfers, hardship, or to facilitate a sale. Treat waivers as a request, not an entitlement.
  • Timing. Profit-based formulas can add verification steps that extend the closing timeline. Build in time for document review.

Tax, legal, and closing mechanics

Flip taxes are internal co-op charges, not city or state transfer taxes. They generally reduce seller proceeds and can affect the amount realized for capital gains calculations. The exact tax treatment depends on your facts, including whether the charge is treated as a selling expense. Speak with your attorney and a qualified tax advisor.

At closing, the co-op’s attorney typically provides a payoff or waiver letter. Closing counsel places that figure on the statement and collects it through escrow. If your building uses a profit-based method, expect to furnish proof of purchase price and capital improvements so the co-op can confirm the calculation.

Next steps

A clear, building-specific model helps you make smarter pricing and offer decisions. If you want a precise net sheet that reflects your co-op’s exact flip-tax formula and today’s market, request a complimentary valuation and proceeds estimate tailored to your apartment.
