- If applicable, check 'Last Name Differs from SS' (Social Security) and/or 'Nonresident Alien'
- Under 'Marital Status', click on the prompt button and select the appropriate status
- In the 'Number of Allowances' field, input the total number of allowances you are claiming. For instructions, see the W-4 worksheet. You may also use the online calculator provided by the IRS
- If you wish to have an additional amount withheld from each paycheck, input it in the 'Additional Amount' field
- Check 'Exempt' only if you meet both of the following conditions:
- Last year I had a right to a refund of all federal income tax withheld because I had no tax liability
- This year I expect a refund of all federal income tax withheld because I expect to have no tax liability
- When finished, click 'I Agree'
- Review your selections; when satisfied, click the submit button
