How to Fill Out a W-4 in 2026

The W-4 form tells your employer how much federal income tax to withhold from each paycheck. The 2020 redesign eliminated the old allowance system — instead, you now enter dollar amounts directly on the form.

The 5 Steps of the 2026 W-4

Step 1 (Required): Your name, address, SSN, and filing status (Single/MFS, MFJ, or HOH).

Step 2 (If applicable): For households with multiple jobs or a working spouse. Check box 2(c) for the higher withholding rate, or use the IRS worksheet to compute a precise dollar adjustment for Step 4(c).

Step 3 (If applicable): Enter the total value of your dependent tax credits — $2,000 per qualifying child under 17, plus $500 per other dependent. This dollar amount reduces the tax withheld per paycheck.

Step 4 (Optional): Enter other income (4a), excess itemized deductions above the standard deduction (4b), and extra withholding per pay period (4c). Step 4(c) is the fine-tuning knob.

Step 5 (Required): Sign and date.

When to Update Your W-4

Update whenever a major life change affects your taxes: marriage, divorce, having a child, a second job, losing a job, buying a home (for the mortgage interest deduction), or receiving a large investment gain. Recalculate every tax year if your income changes significantly.

FAQ

W-4 withholding questions answered

How do I fill out a W-4 for 2026?
Step 1: filing status. Step 2: multiple jobs adjustment (if applicable). Step 3: dependent credits ($2,000/child under 17, $500/other dependent). Step 4: optional — other income, excess deductions, extra withholding. Step 5: signature. Use this calculator to get the exact dollar amounts for Steps 3, 4(b), and 4(c).
Should I claim 0 or 1 on my W-4?
The 2020+ W-4 no longer uses allowances. Leave Step 3 blank if you have no dependents, leave Step 4 blank for a single job with standard deduction — withholding defaults to the standard rate for your filing status and pay frequency. No "0 or 1" decision is needed.
What is Step 2 on the W-4 for?
Step 2 handles two-income households. Check box 2(c) for higher withholding if you and your spouse both work at similar salaries. Or use the IRS withholding worksheet to calculate a precise extra-per-paycheck amount for 4(c) if your jobs have very different pay levels.
How do I change my W-4 withholding?
Submit a new Form W-4 to HR or payroll at any time. Your employer must apply it within 30 days. You can submit a new W-4 as often as needed — there's no penalty for updating it.
What happens if I don't fill out a W-4?
Your employer withholds as if you're single with no adjustments — maximum default withholding for your pay level. This typically over-withholds, giving the IRS an interest-free loan until you file. Filing a proper W-4 lets you right-size your withholding.
