How to Fill Out a W-4
The number of allowances you claim on your W-4 Form determine the rate at which Federal and State income taxes are withheld from your paycheck.
If you're unsure whether you are entitled to claim a certain number of allowances or exemption from withholding, it is best that you contact your tax advisor. If you would like to research it on your own, you may find the information you need in IRS publications #4 (Students Guide to Federal Income Tax) and #505 (Tax Withholding and Estimated Tax) both of which contain instructions on how to determine your withholding. Both pamphlets are located on the IRS Publications Web-site. You may also want to view the 2019 W-4 witholding certificates.
You can also calculate your paycheck at different withholdings by using the Paycheck Calculator. Be sure that your use the calculator based on your pay schedule.
If you are not a U.S. Citizen, any changes to your payroll withholding status need to be completed in the Payroll Services Office, building 1, room 107.
