📖 How to Fill Out Form W-4 (2026)

The IRS redesigned Form W-4 in 2020 — there are no longer "withholding allowances." Instead, there are 5 straightforward steps. Here's exactly what to enter for 2026:

👤 Step 1

Personal Information

Enter your legal name, address, Social Security Number, and select your filing status. Your filing status is the most important factor — it determines your standard deduction and tax bracket.

💡 Pro tip: If you're single, choose "Single." If married and both spouses work, choosing "Married Filing Separately" here often avoids under-withholding.
💼 Step 2

Multiple Jobs or Spouse Works

Complete this step only if you have more than one job or are married and both spouses work. Choose one of three options: (a) Use the IRS online estimator, (b) Use the Multiple Jobs Worksheet on page 3, or (c) Check the box if there are only two jobs total and incomes are similar.

💡 Pro tip: The simplest option: check the box in Step 2(c) if you and your spouse each have one job and similar incomes. This causes extra withholding but avoids a year-end bill.
👨‍👩‍👧 Step 3

Claim Dependents

Enter $2,000 for each qualifying child under age 17, and $500 for each other dependent (parents, older children, etc.). Only complete this step if your income is $200,000 or less (single) or $400,000 or less (married filing jointly). Enter the total dollar amount — not the number of dependents.

💡 Pro tip: 2026 Child Tax Credit: $2,000 per qualifying child under 17. Enter the total in dollars (e.g., 2 children = $4,000 on line 3).
🔧 Step 4

Other Adjustments (Optional)

4a — Other income: If you have income not subject to withholding (dividends, freelance, retirement), enter the annual total here to withhold taxes on it.

4b — Deductions: If you plan to itemize and your deductions exceed the standard deduction ($16,100 for single / $32,200 for MFJ), enter the excess here.

4c — Extra withholding: Enter any extra amount to withhold from each paycheck.

💡 Pro tip: Most people skip Steps 4a and 4b. Use 4c to fine-tune withholding after using the IRS estimator.
✍️ Step 5

Sign and Date

Sign and date the form and give it to your employer's HR or payroll department. Your employer is not required to verify your withholding — the responsibility is yours.

💡 Pro tip: Submit a new W-4 whenever your tax situation changes: marriage, divorce, new child, second job, major income change, or buying a home.

Frequently Asked Questions

Q: How often should I update my W-4?
A: Update it whenever your situation changes — new job, marriage, divorce, baby, major raise, or after filing taxes and finding you owed a large amount.
Q: What happens if I don't submit a W-4?
A: Your employer withholds taxes at the highest "Single with no adjustments" rate — usually causing a refund, but reducing your take-home pay.
Q: Can I claim exempt from withholding?
A: Yes, if you had no federal tax liability last year and expect none this year. Write "Exempt" on W-4 line 4c. This is different from claiming dependents.
Q: Does the W-4 affect FICA (Social Security & Medicare)?
A: No. SS (6.2%) and Medicare (1.45%) are always withheld regardless of your W-4 settings. OBBBA 2026 exclusions do not reduce FICA.
Q: What are the OBBBA 2026 changes for W-4?
A: Overtime pay up to $12,500/year and tips up to $25,000/year are now excluded from federal income tax. Employers may need to adjust withholding systems. Use this calculator to see the impact.
