How to adjust your W-4 for 2026

The W-4 is the dial between your paycheck and your refund. Turn it one way for more money now, the other for a bigger check in spring.

Short answer

To get bigger paychecks (smaller refund), enter your children in Step 3 ($2,200 each) and expected deductions — including the new tips, overtime, car-loan and senior deductions — in Step 4(b). To get a bigger refund (or stop owing), check Step 2 if you have two jobs, add other income in Step 4(a), or ask for extra withholding per check in Step 4(c). Give the new form to your employer; it takes effect within a pay period or two.

What each step does to a $60,000 paycheck

Here is how common changes move a biweekly paycheck for a single filer earning $60,000 (top bracket 12%). Green raises take-home pay; red lowers it.

Step by step

  1. Step 1 — filing status. Check single, married filing jointly or head of household. Choosing HoH when you qualify lowers withholding immediately.
  2. Step 2 — multiple jobs or a working spouse. This is the most important fix for people who owe. With jobs of $50,000 and $40,000 and only “Single” checked on each, payroll withholds about $6,440 in total, but tax on $90,000 is $10,970 — a $4,530 surprise. Checking the box on both W-4s (or using the IRS Tax Withholding Estimator) closes the gap.
  3. Step 3 — dependents. $2,200 per child under 17 and $500 per other dependent, if your income is under $200,000 ($400,000 joint).
  4. Step 4(a) — other income without withholding: interest, dividends, a side gig.
  5. Step 4(b) — deductions. The 2026 worksheet now has lines for qualified tips (up to $25,000), qualified overtime (up to $12,500 / $25,000) and qualified car-loan interest (up to $10,000), alongside itemized deductions. Seniors can include the extra deductions for age 65+ here too.
  6. Step 4(c) — extra withholding. A flat dollar amount per paycheck. Simple and precise if you just want a bigger refund.

Which should you choose: paycheck or refund?

Financially, a refund is an interest-free loan to the Treasury; with high-yield savings paying around 4%, a $3,000 refund costs roughly $60 a year in lost interest. Behaviorally, many people like the forced savings — and that’s a fine reason. What you want to avoid is owing: if you owe more than $1,000 and paid less than 90% of this year’s tax (or 100% of last year’s), an underpayment penalty can apply.

Good moments to revisit the W-4: a new job or second job, marriage or divorce, a baby, a child turning 17, a big raise, starting to earn tips or regular overtime, buying a new U.S.-assembled car, or turning 65. If you didn’t file a new W-4 after 2019, you’re still on the old allowances system — redoing it on the 2026 form is worth ten minutes.

Frequently asked questions

How do I get a bigger tax refund?

Have more withheld: check Step 2 if you or your spouse have more than one job, list other income in Step 4(a), or add an extra amount per paycheck in Step 4(c). Leaving Step 3 and Step 4(b) blank also keeps credits and deductions for your refund.

How do I get more money in my paycheck instead of a refund?

Enter your Child Tax Credit amount in Step 3 ($2,200 per child under 17) and expected deductions — tips, overtime, car-loan interest, itemized deductions — in Step 4(b) of the 2026 W-4.

Does the 2026 W-4 include no tax on tips and overtime?

Yes. The 2026 Step 4(b) deductions worksheet has lines for qualified tips, qualified overtime and qualified passenger-vehicle loan interest.

How often can I change my W-4?

Any time. Employers must apply a new W-4 no later than the start of the first payroll period ending 30 days after you submit it.

What happens if I don’t check Step 2 with two jobs?

Each employer withholds as if its job were your only income, applying the full standard deduction and low brackets twice. You’ll likely owe at tax time.
