How to Fill Out Your W-4 in 2026: Step-by-Step Guide

Last updated:

The W-4 tells your employer how much federal income tax to withhold from each paycheck. Getting it right means no surprise tax bill in April and no over-withholding through the year.

What changed in 2020 and why it still matters

The redesigned W-4 removed allowances. Steps 2 through 4 are optional, but they can materially affect withholding accuracy when you have multiple jobs, dependents, other income, deductions, or a specific extra-withholding target.

Step-by-step: the 5 steps on Form W-4

  1. Step 1: Personal info. Enter identifying details and choose filing status.
  2. Step 2: Multiple jobs or spouse works. Use this when household income comes from more than one job.
  3. Step 3: Dependents. Enter eligible dependent credits when they apply.
  4. Step 4: Other adjustments. Add other income, deductions, or extra withholding.
  5. Step 5: Signature. Sign and submit the form to your employer.

Frequently Asked Questions

Do I need to fill out a new W-4 every year?

No. You usually submit a new W-4 only when your job, filing status, dependents, second-job situation, deductions, or extra-withholding preference changes.

What happens if I claim 0 on my W-4?

That wording no longer applies to the redesigned W-4. The post-2020 form removed withholding allowances, so payroll uses filing status and Steps 2 through 4 instead.

How do I withhold extra tax?

Use Step 4(c) on Form W-4 to enter an additional dollar amount to withhold from each paycheck.
