About Form W-4
IRS Form W-4 (Employee's Withholding Allowance Certificate) determines the amount of federal and state income tax withholding deducted from an employee's wage payment. Federal regulations require a Form W-4 from all employees*.
Employee Services submits copies of Form W-4 to the IRS when requested, and the employee may be restricted in changing his/her tax status until Employee Services has received written authorization from the IRS.
Important: A current tax year W-4 Form is required when setting up or making changes to tax withholding deductions.
Accessing, Completing and Submitting Form W-4
Download the current-year Form W-4, or request it from your department. When completing the W-4, employees should follow the instructions provided on the form and on the W-4 Instructions sheet, and fill it out using blue or black ink (pencil invalidates the form).
Employees should either submit the original Form W-4 to their department payroll liaison or mail the original Form W-4 directly to Employee Services (see address on W-4 Instructions sheet). Only original documents are valid; copies and facsimiles will not be accepted.
Note: Forms not received by the published due date for a specific pay cycle will not take effect until the next payroll cycle. Check the payroll production calendar. Improperly completed/incomplete forms will be returned to the employee to correct or replace, and the taxes that are withheld as a result of the improper information cannot be refunded.
Failure to complete a Form W-4 also will result in withholding taxes being calculated at single status and zero allowances. This is the highest tax withholding rate. Taxes withheld due to an employee failing to complete a W-4 by the appropriate payroll deadline cannot be refunded.
Claiming Exemption from Tax Withholding
Employees who claim "exempt from withholding" must file a new W-4 with Employee Services by Feb. 1 of each year. Failure to submit a new Form W-4 by February 1 will result in withholding of single status and zero allowances, the highest rate. Note: A current year tax form is required.
Additional Federal/State Withholding
To have an additional flat dollar amount withheld for federal and/or state income tax, or to change (replace) an existing additional amount, download the Additional Federal/State Tax Withholding Request Form. Complete and submit the original form to Employee Services. Only original documents are valid; copies and facsimiles will not be accepted.
This withholding will be in addition to the amount currently deducted, based on the marital status and number of allowances claimed on Form W-4. If the form is not received by the published due date, it will take effect for the next payroll cycle.
To cancel a request for additional federal and/or state income tax withholding, complete and submit the original Additional Federal/State Tax Withholding Cancellation Form. Only original documents are valid; copies and facsimiles will not be accepted.
Payroll due dates for submission of the W-4 Form are available via the payroll production calendar, or employees may contact their payroll liaison.
The additional federal withholding amount is deducted on the monthly payroll (for monthly-paid employees) and/or on the second biweekly payroll (for biweekly-paid employees). Changes made to the flat dollar amount will replace the old value.
Example: The old amount was $50 and the new amount you wish to have deducted is $75. Record $75 on the form to update this amount. Do not record $25.
