Form W-4

Disclaimer:

Central Human Resources employees are not tax specialists. By law, we are unable to provide any advice on completing Form W-4.

Who should complete a Form W-4?

If you are a new hire in 2020 or if you wish to update your current W-4 for payroll dated after January 1, 2020.

Form W-4 is designed to help employees more accurately calculate their withholding allowances. Withholding is an individual decision based on each person’s financial and personal situation. Each employee must make withholding decisions on their own, or with the assistance of their individual tax consultant. The UW is not authorized to provide tax advice.

If you want to complete a new Form W-4

If you decide that you would like to complete a new form, you can submit a Form W-4 (see below) to the Central Human Resources office, Engelmann 125. Before completing the 2020 form, please read the instructions included with the form.

You must complete Step 1 (personal information) and Step 5 (signing the form).

Steps 2, 3, and 4 are optional, but completing them will help ensure that your federal income tax withholding will more accurately match your tax liability.

  • Step 2 is for households with multiple jobs.
  • Step 3 is used to claim tax credits for dependents.
  • Step 4 is for other adjustments (additional income such as interest and dividends, itemized deductions that exceed the standard deduction, and extra tax you want withheld).

Wisconsin Residents

Form W-4 requires Wisconsin residents to complete the Wisconsin Form WT-4 if adjusting Wisconsin state taxes. If no change is needed for current Wisconsin tax setup, you do not need to submit a revised Form WT-4.

Illinois, Minnesota, California Residents

The UW is now able to withhold tax for these three states if you meet the necessary requirements. If you would like taxes withheld, please submit that respective state’s W-4.
