New York Trust Accounting Forms are specific forms that trustees in the state of New York must use when reporting and accounting for trust assets. There are several types of New York Trust Accounting Forms, including the Form IT-205 (NY Trust Tax Return), Form IT-206 (Trust Accounting Income Tax Return) and Form IT-209 (Trust Tax Payment Voucher). These forms are used to report income and expenses of a trust, account for trust assets and liabilities, and to pay taxes on trust income. They provide a detailed record of the activities of the trust, and are required by the New York State Department of Taxation and Finance.
