Employees will have access within Employee Self-Service that will allow the ability to view and/or update their Form W-4 Tax Information.

You must complete Form W-4 so the Payroll Department can calculate the correct amount of tax to withhold from your pay.  Federal income tax is withheld from your wages based on marital status and the number of allowances claimed on this form.  You may also specify that an additional dollar amount be withheld.  You can file a new Form W-4 anytime your tax situation changes and you choose to have more, or less, tax withheld.  Whether you are entitled to claim a certain number of allowances or exemption from withholding is subject to review by the IRS.  Your employer may be required to send a copy of this form to the IRS.

Important Reminders:

  • For detailed information on how to complete your W-4, please refer to the IRS W-4 page:
  • Your online W-4 submission updates your Federal Tax Data only. If you need to update your State Withholdings, you must submit a written request.
  • Employees of Agencies that utilize the MassHR Employee Service Center (ESC) should contact the ESC with W-4 related questions by calling 1-855-4HR-SPPT (1-855-447-7778) or for TTY users: (617) 248-0546.
