The New York Mortgage Recording Tax Return is a form used to report the tax on a mortgage loan originated in the state of New York. The New York State Department of Taxation and Finance requires this form to be completed and submitted when a loan that is secured by real property within the state is recorded. The tax is imposed on the borrower and is based on the amount of the loan. There are two types of New York Mortgage Recording Tax Returns: Form MT-15, which is used for residential mortgages, and Form MT-15M, which is used for commercial mortgages. Both forms require the borrower to provide information such as the mortgage loan amount, the name and address of the mortgage lender, the address of the property being mortgaged, and the date the loan was originated. The forms also require the borrower to calculate and report the amount of tax due. The tax rate varies depending on the county in which the property is located.
