Form W-4: Employee's Withholding Certificate
Completed by an employee so their employer can withhold the correct amount of federal income tax from their pay.
What Form W-4 is for
W-4 tells your employer how much federal income tax to withhold from your pay. You give it to the employer rather than to the IRS, and the withholding that results is subject to review. It is worth completing a new one when your circumstances change, not only when you start a job.
Who uses it
- Someone starting a new job
- Anyone whose filing status, second job or dependants have changed
- Anyone who owed tax or took a large refund last year and wants to adjust
What the form asks you for
- Name, address and social security number
- A filing status: single or married filing separately, married filing jointly or qualifying surviving spouse, or head of household
- Details of multiple jobs or a working spouse
- Dependants, other income, deductions and any extra amount to withhold
