Form W-4

Employee form that determines federal tax withholding from paychecks.

Form W-4 (Employee's Withholding Certificate) is completed by employees to tell their employer how much federal income tax to withhold from each paycheck. The form accounts for filing status, dependents, other income, deductions, and extra withholding. The 2020 redesign eliminated allowances and uses a more straightforward approach.

Example

A new hire completes a W-4 claiming married filing jointly with two dependents—the employer uses this information to calculate the correct federal withholding from each paycheck.

Why It Matters for Your Business

An incorrect W-4 leads to either too much withheld (reducing your cash flow) or too little (resulting in a tax bill and possible penalties at filing time).
