What is Form W-4?
Form W-4 (Employee’s Withholding Certificate) is an IRS form that employees complete to inform their employer how much federal income tax to withhold from each paycheck. The information on this form ensures that withholding is accurate, helping employees avoid overpaying or underpaying federal taxes throughout the year.
The form includes sections for:
- Personal information
- Multiple jobs or working spouse
- Dependent claims
- Other income and deductions
- Additional withholding
Accurate and timely updates to Form W-4 reduce the risk of a large tax bill or refund when filing annual taxes.
