Tax Law, §§ 1401, 1402, 1405-B
As used in this Part, unless otherwise expressly stated, the terms set forth in this section are defined as follows:
Example 1:
A three-family house is sold for $850,000. The grantee assumed an existing $200,000 mortgage, obtained an additional $550,000 mortgage from a bank and paid $100,000 in cash. The tax is imposed upon $650,000, because the $850,000 consideration is reduced by the $200,000 mortgage which remained on the qualifying residential property at the time of the sale. However, the $850,000 cannot be reduced by the new $550,000 mortgage obtained by the grantee in connection with the sale. The result would have been the same if the grantee had purchased the property subject to an existing $200,000 mortgage which remained on the property at the time of the sale.
Example 2:
A commercial building is sold for $800,000. The grantee assumed an existing $300,000 mortgage and paid $500,000 in cash. The tax is imposed on the entire $800,000 because the consideration exceeds $500,000 and the building is not qualifying residential property. No exclusion is allowed for the existing $300,000 mortgage. The result would have been the same if the grantee had purchased the property subject to an existing $300,000 mortgage and/or obtained an additional mortgage with respect to the $500,000.
Example:
An individual purchased fifty percent of the stock of the ABC corporation which owned real property with a fair market value of $300,000. The ABC corporation would compute the transfer tax due on this conveyance of an interest in real property based upon consideration of $150,000 ($300,000 × 50 percent).
Example:
A leases real property to B for a term of 20 years. The lease does not contain any option to purchase the real property. In year five of the lease, B assigns its leasehold interest to C for $100,000. B owes transfer tax on the assignment. The tax is computed on consideration of $100,000.
