Optional, and no email required. The borough and ZIP decide which transfer tax treatment applies to your building, and the property type decides whether a flip tax belongs in the math at all, so the estimate below adjusts the moment you enter them.

Estimated net proceeds

Mansion tax

The mansion tax starts at $1 million and is paid by the buyer, not you.

Every figure is an estimate, not a quote. The costs are set by the contract, the managing agent and the closing.

The flip tax line reflects only the percentage you entered. Confirm your building's figure in writing before you rely on it.

How NYC seller closing costs work

The single biggest line on most NYC net sheets is the broker commission, which is negotiable and set in your listing agreement. After that, sellers in New York City pay two transfer taxes that catch many first-time sellers off guard. The NYC Real Property Transfer Tax is 1% of the price up to $500,000 and 1.425% above $500,000. The New York State transfer tax is 0.4% of the price, rising to 0.65% on residential sales of $3 million or more inside New York City. That supplemental 0.25% applies only in cities of one million or more, so a Hudson Valley or Westchester sale stays at 0.4% at any price. Both are paid by the seller.

The mansion tax is the buyer's cost, not yours

New York's 1% to 3.9% mansion tax on sales of $1 million and up is paid by the buyer, not the seller, so it does not come out of your proceeds. It can still affect negotiation, because a buyer factors their total cash-to-close into the offer.

If you own a co-op, your building may charge a flip tax when you sell. It is set by the building, not the city, and ranges widely, often 1% to 3% of the price, a flat per-share amount, or a percentage of your profit. Check your proprietary lease or ask the managing agent for the exact figure, since it comes straight out of your proceeds. Condos and houses generally have no flip tax. Round out the sheet with your attorney fee, any building move-out or processing fees, and the payoff of your remaining mortgage balance.

The calculator above gives a fast, realistic estimate. For an exact number, the variable that matters most is your building's specific flip tax and the comparable sale prices in your line, which is where a real comparative market analysis comes in. You can also see the buyer's side of the table on the closing cost calculator and read the full NYC closing costs breakdown. When you are ready to plan a sale, start with the sell your NYC property page.

The next step

What the estimate above cannot know

The estimate uses the percentages you typed in. A net sheet for your building uses the flip tax the managing agent actually publishes, confirmed in writing, and the recent comparable sales in your line. That part takes a person. No cost and no obligation.

Your building's flip tax, confirmed against the proprietary lease or with the managing agent

A realistic asking-price range and what you would keep at each point in it

Common questions about seller proceeds in NYC

Who pays the transfer taxes when you sell in NYC?

The seller pays both the NYC Real Property Transfer Tax (1% up to $500,000, 1.425% above) and the New York State transfer tax (0.4%, or 0.65% on NYC residential sales of $3 million or more). These come out of your proceeds at closing.

Do I pay the mansion tax when I sell?

No. The mansion tax on sales of $1 million and up is paid by the buyer, not the seller, so it does not reduce your net proceeds.

What is a co-op flip tax and how much is it?

A flip tax is a transfer fee your co-op building charges when you sell. The building sets it, so it varies widely, often 1% to 3% of the price, a flat per-share amount, or a share of your profit. Ask your managing agent for the exact figure, because it comes out of your proceeds. Condos and houses usually have none.

How much are total seller closing costs in NYC?

Including the broker commission, most NYC sellers see total costs in the range of 6% to 10% of the sale price. Commission is the largest piece and is negotiable. Transfer taxes, attorney fees, and a co-op flip tax make up the rest.

Is the broker commission a fixed rate?

No. Commission is always negotiable and is set in the listing agreement you sign. The calculator lets you enter whatever rate applies to your sale.
