What the Tax Return IT2104 is and when it applies

The Tax Return IT2104 (Form IT-2104) is New York State’s Employee’s Withholding Allowance Certificate used by employees to establish state and local income tax withholding. Employers collect a completed IT-2104 to determine the correct amount of New York State and local tax to withhold from wages. Employees complete IT-2104 when starting a job, after a change in withholding status, or when exemptions change. The form affects payroll withholding calculations but does not replace annual tax filing; it only adjusts payroll withholding throughout the year.

Why accurate completion of IT-2104 matters

Completing IT-2104 correctly ensures payroll withholds align with your tax liability, reducing the risk of underpayment penalties or large year-end balances while avoiding unnecessary over-withholding during the year.

  • New Employees who start work and must set state withholding allowances
  • Payroll Administrators who process withholding and retain payroll records
  • HR Professionals who manage onboarding and updates to employee tax data
