On February 25, 2026 By newsroom Topic: Taxes

The W-4, or "Employee's Withholding Certificate," helps employers determine how much federal income tax to withhold from your paycheck. Here’s a breakdown of what it is, how to fill it out, and why it’s important.

What Is a W-4?

Purpose: Ensures accurate withholding of federal income taxes.
When to Use:
When starting a new job.
To adjust withholding after major life changes (e.g., marriage, new dependents, or additional income sources).
If you owe taxes or receive a large refund, to better match your tax liability.

How to Fill Out a W-4

Step-by-Step Instructions:
1. Enter Personal Information:
- Provide your name, address, Social Security number, and filing status (single, married, head of household).
2. Account for Multiple Jobs:
- For multiple jobs or dual incomes (e.g., you and your spouse), follow instructions for accurate withholding.
- Optionally, check box 2(c) if you have two jobs with similar income.
- If you prefer privacy, you can adjust withholding using line 4(c).
3. Claim Dependents:
- If your income is below $200,000 (or $400,000 for joint filers), claim dependents to reduce withholding.
4. Refine Withholdings:
- Add extra withholding amounts or include deductions beyond the standard deduction, if applicable.
5. Sign and Submit:
- Sign and date the form. Submit it to HR or payroll, or complete it online if available.
