The New York Annual Income Worksheet (UD-8(1)) is a form used by New York taxpayers to calculate their income for a taxable year. It is part of the New York State Department of Taxation and Finance's annual income tax filing system. The form requires taxpayers to provide information on their gross income, deductions, and other income sources in order to calculate their New York State income tax liability. The form is divided into two parts: Part 1 is used to calculate the taxpayer’s income and Part 2 is used to calculate the taxpayer’s deductions. There are three types of New York Annual Income Worksheets (UD-8(1)): the Standard Form, the Nonresident and Part-Year Resident Form, and the Resident and Part-Year Resident Form.
