What to know about Form W-4
- Give the completed form to your employer. It tells them how much federal income tax to withhold from your pay.
- Step 1 (your details) and Step 5 (your signature) are required. Steps 2 to 4 only apply if your situation calls for them.
- A W-4 stays in effect until you replace it, so update it when things change, such as a new job, marriage, or a new child.
- If you claim exemption from withholding, the claim expires and has to be renewed each year.
Have these ready
- Your legal name and address
- Your Social Security number or EIN, whichever the form asks for
- The name of whoever requested the form, so it goes to the right person
