New York City lawmakers are pushing to expand the Mansion Tax, and the proposed changes would affect far more homeowners than the current version. The existing Mansion Tax is a 1% surcharge on residential property sales of $1 million or more. The expansion would lower the threshold, increase the rate at higher price points, and potentially apply to co-op and condo transfers that are currently structured to minimize tax exposure.
How the Current Mansion Tax Works
Under current law, any residential property sale at or above $1 million triggers a 1% tax paid by the buyer. For properties above $2 million, an additional “supplemental” tax applies at graduated rates that climb with the sale price, reaching nearly 4% on sales above $25 million. The tax was originally designed to apply only to luxury transactions, but in a city where the median home price in several boroughs exceeds $800,000, the $1 million threshold captures an increasing number of ordinary home sales.
What the Expansion Would Change
The proposed expansion would lower the threshold below $1 million in some versions, which would sweep in a huge number of transactions on Staten Island and in Brooklyn that are currently just below the cutoff. It would also increase the graduated rates at higher price points and close loopholes that allow some co-op sales to avoid the tax through share transfer structures.
For a buyer purchasing a $950,000 home on Staten Island that currently falls just below the Mansion Tax threshold, even a modest reduction in the trigger point could add $9,500 to $19,000 in additional closing costs. In Brooklyn, where a growing share of sales are in the $800,000 to $1.2 million range, the expansion would hit a large volume of transactions.
Why This Matters for Buyers
Closing costs in New York City are already among the highest in the country. Buyers typically pay 3-6% of the purchase price in taxes, attorney fees, title insurance, and lender charges. Adding or expanding a Mansion Tax layer makes buying even more expensive and could push some buyers out of price ranges they can currently afford.
For first-time buyers in particular, every dollar of closing costs matters. An expanded Mansion Tax is essentially a tax on entering the housing market, which contradicts the city’s stated goal of making homeownership more accessible.
What Homeowners Should Watch For
If you are thinking about selling in the next year or two, the timing of the Mansion Tax expansion could affect your buyer pool. A higher tax burden on buyers reduces their effective purchasing power, which could put downward pressure on sale prices, particularly at price points just above whatever threshold is ultimately set.
