W-4 Overtime & Tips Withholding Calculator (2026)
The 2025 law's no tax on tips and no tax on overtime deductions are claimed when you file — so all year your employer keeps withholding federal income tax as if that money were fully taxable, and you get it back as a bigger refund next spring. You don't have to wait. This tool estimates the deduction you'll actually get and tells you exactly what to enter on your 2026 Form W-4 Step 4(b) Deductions Worksheet so your employer withholds less now — turning that once-a-year refund into more take-home every payday. Everything runs in your browser; nothing is uploaded.
Companion to the filing-time tools. The no tax on overtime calculator and no tax on tips calculator answer "how much will this deduction save me on my return?" This one answers the other half: "how do I get that money in my paychecks now instead of as a refund?"
Estimate for general guidance only — not tax advice. Withholding is an approximation: Publication 15-T's built-in standard-deduction proxy and your Step 2 checkbox affect which bracket your adjusted wage lands in, so the per-paycheck figure is an estimate, not a guarantee. Figures use the 2026 federal brackets and standard deduction. This tool is federal-only — it does not model state withholding (most states don't conform; see the state pages) or FICA. Verify with the IRS or a tax professional.
Read this before you touch your W-4
1. Use Step 4(b), never Step 4(c). Step 4(b) is Deductions — it lowers the income your employer withholds on, so your paycheck goes up. Step 4(c) is extra withholding — it makes your paycheck go down. To keep more of your tips and overtime now, you increase the Step 4(b) deduction total. Never use 4(c) for this.
2. It's a deduction, not a paycheck exemption. Employers withhold on tips and overtime by default; nothing is automatic. The W-4 is the only lever, and it's optional — doing nothing just means a bigger refund, not a lost deduction.
3. A big refund isn't a bonus — it's your money the IRS held interest-free. Over-withholding on tips and overtime all year is an interest-free loan to the government. Adjusting Step 4(b) fixes it and moves the money into your paychecks.
4. Overtime means the premium only. Just the extra "half" of time-and-a-half qualifies — not your full overtime pay. That's the "and-a-half portion" line 1b asks for.
5. FICA still applies. Social Security and Medicare come out of every tip and overtime dollar regardless. This only reduces federal income-tax withholding.
6. Your W-2's new TT / TP boxes are for next April, not your paycheck. Box 12 code TT (overtime premium) and TP (tips) are year-end reporting you use to file — they don't change withholding. What each code means (and the new Box 14b occupation codes) is decoded in the W-2 box decoder.
How the Step 4(b) adjustment works
The timing gap. The no-tax-on-tips (Internal Revenue Code §224) and no-tax-on-overtime (§225) deductions are claimed at filing on your 2026 return (new Schedule 1-A). Your paycheck doesn't automatically know about them, so your employer withholds federal income tax as if that income were fully taxable. The result is over-withholding all year — money that comes back as a refund instead of showing up now.
What actually changed on the 2026 W-4. There's no new "step" and no separate overtime/tips worksheet. The 2026 Form W-4 added new lines 1a (qualified tips) and 1b (qualified overtime) to the pre-existing Step 4(b) Deductions Worksheet on page 4. You estimate your tips on line 1a and your overtime premium on line 1b; they roll up through line 2 into the line-15 total, which you copy to Step 4(b) on the form itself.
Why that lowers withholding. Publication 15-T has your employer subtract your Step 4(b) amount from your annualized wages before applying the tax brackets. So adding a deduction to Step 4(b) lowers your annual withholding by about that deduction times your marginal rate — and dividing by your number of pay periods gives the extra take-home per check.
The caps and the phase-out. Tips are deductible up to $25,000; the overtime premium up to $12,500 ($25,000 if married filing jointly). Both shrink by $100 for every $1,000 your income is over $150,000 ($300,000 joint). The W-4 worksheet uses a simple income cliff at that line, but the real filing-time deduction phases out gradually — so this tool computes the accurate gradual figure and, if your income is above the line but not fully phased out, tells you that you can enter that more accurate number straight on Step 4(b) rather than needlessly entering $0.

A worked example: Marisol the server
Marisol is single, expects about $38,000 of income in 2026, and is paid every two weeks (26 paychecks). She expects roughly $18,000 of tips for the year and works no overtime. Here's what the tool tells her:
- Line 1a (qualified tips): her $18,000 of tips is under the $25,000 cap and her income is under the $150,000 phase-out line, so the full $18,000 is deductible.
- Line 1b (qualified overtime): $0 — she works no overtime.
- What she enters on the W-4: $18,000 on Step 4(b) Deductions Worksheet line 1a, which adds $18,000 to her Step 4(b) total (line 15).
- Annual withholding reduction: that $18,000 comes off income in her bracket, cutting her annual federal withholding by about $1,990.
- Extra take-home per paycheck: $1,990 ÷ 26 ≈ $76.54 more in every biweekly check — instead of a $1,990 refund a year later.
Marisol still has Social Security and Medicare withheld on all her tips, and if her state doesn't conform she still owes state tax on them. The W-4 change only touches federal income-tax withholding — but it puts about $77 back in each paycheck now.
Common questions
Do I have to wait until I file? No. That's the whole point of this tool. Put an estimate of the deduction on your 2026 W-4 Step 4(b) Deductions Worksheet and your employer withholds less each payday. Doing nothing is fine too — you just get it back as a refund.
Step 4(b) or Step 4(c)? Step 4(b), Deductions — it lowers withholding and raises take-home. Step 4(c) is extra withholding and does the opposite; don't use it for this.
How much overtime qualifies? Only the premium — the extra "half" of time-and-a-half, not your full overtime pay. It's the same amount that appears in W-2 Box 12 code TT.
What is my marginal rate? It's the tax rate on your next dollar of income. Your withholding reduction is roughly the deduction times this rate.
What is withholding? It's the federal income tax your employer holds back from each paycheck and sends to the IRS on your behalf. Step 4(b) tells the employer to hold back less.
How does filing status matter? It sets your brackets, your caps, and your phase-out threshold. Married workers must file jointly to claim these deductions.
What are the W-2 TT and TP boxes? On your 2026 W-2, Box 12 code TT reports your qualified overtime (premium only) and TP reports your tips — the real figures you use to file next year. They don't change your paycheck.
Does my state tax change? Usually no — most states don't conform to these federal deductions, so your state withholding is unaffected. Check your state's page for its rule.
Is anything saved or uploaded? No. The tool is fully client-side — your numbers never leave your browser.
