Additional withholding requested on Form IT-2104
An additional withholding amount may be requested for New York State, New York City, or Yonkers (or any combination of these), by an employee/payee trying to avoid under withholding. The employee/payee makes the request by entering a specific dollar amount on lines 3 through 5 of their Form IT-2104 . If you agree to withhold an additional amount, figure the amount that you would have withheld based on the number of exemptions claimed, then add the additional amount requested to this figure. Withhold the total amount from wages.
