The mansion tax is a tax imposed by the state of New York on real estate transactions involving high-end properties. In New York City, the mansion tax scale is as follows:

• For properties selling for between $1 million and $1.99 million, the mansion tax is 1% of the sale price.
• For properties selling for between $2 million and $2.99 million, the mansion tax is 1.25% of the sale price.
• For properties selling for between $3 million and $4.99 million, the mansion tax is 1.5% of the sale price.
• For properties selling for $5 million or more, the mansion tax is 2.25% of the sale price.

It’s worth noting that these rates apply only to properties located in New York City. Properties located elsewhere in the state of New York are subject to a different mansion tax scale. Additionally, if the property being sold is a co-op, the mansion tax is calculated based on the pro rata share of the value of the underlying real estate.
