Does W-4 claim my deduction?
No. A W-4 estimates withholding from future paychecks. Your income tax return determines the deduction you actually qualify to claim.

Overtime and your 2026 W-4
Account for the deduction. Understand the paycheck change.
You can account for an expected qualified overtime deduction on your 2026 W-4. Updating the form changes federal income tax withheld from future checks; your tax return determines the deduction you actually qualify to claim.
Based on the IRS August 2026 overtime FAQ, questions 8–9 and 19.
Where qualified overtime goes on the form
Overtime still has federal income tax withheld. An employer needs an updated, valid W-4 to account for this deduction; the overtime deduction does not exempt wages from payroll taxes. For 2026, employers report qualified overtime on W-2 box 12 using code TT. IRS overtime FAQ, questions 1 and 8–10.
- Start with the 2026 Deductions Worksheet. On page 4, line 1b covers expected qualified overtime if total income is below $150,000, or $300,000 for joint filers. Its limits are $12,500 and $25,000, respectively.
- Finish the entire worksheet. Carry line 15 to step 4(b). Gross overtime pay is not the same as the qualified premium.
- Account for multiple jobs. Use step 2; complete steps 3 through 4(b) for only one job, preferably the highest paying. Step 4(c) adds extra withholding per pay period.
Interactive illustration · Fixed example
An annual deduction is not a remaining-year payout
Change the payroll schedule and checks left to see how timing affects the same annual adjustment.
Our example: $3,000 annual qualified overtime premium × an assumed 22% marginal rate = approximately $660 less annual federal income tax.
Assumes the same $3,000 annual step 4(b) adjustment takes effect for every remaining check.
Approximate reduction per check
$25.38
Across 8 remaining checks$203.08
Across a full year$660.00
$660 ÷ 26 × 8 = $203.08 over the remaining checks.
Illustrative withholding change, not a refund estimate or a recommended W-4 entry.
What this example assumes
One job; single filing; eligibility for the full $3,000 deduction; income below the worksheet threshold; no other adjustments; sufficient federal income tax withholding; and an unchanged 22% marginal rate throughout the calculation. Bracket crossings, payroll methods, rounding and varying overtime can change the result.
Original illustrative arithmetic based on the annual treatment of step 4(b) in IRS Publication 15-T, Steps 4(a) and 4(b), and Worksheet 1A.
Why eight checks do not deliver the full $660
Payroll treats step 4(b) as an annual reduction in the wages used to calculate withholding. The ordinary periodic calculation uses the annual payroll frequency. It does not divide the entire estimated annual tax saving by the checks left this year. IRS Publication 15-T.
In the example, $660 ÷ 26 is about $25.38 per check. With eight checks left, the same setting changes withholding by about $203. Changing withholding does not increase the deduction itself.
Do not turn this illustration into a catch-up entry. A remaining-year adjustment depends on wages already earned, tax already withheld, other income, credits and filing status. The gap between the example’s annual and remaining-year amounts does not establish a refund or balance due.
| Amount | What it represents |
|---|---|
| Qualified premium | Compensation eligible for consideration under the overtime deduction rules. |
| Deduction | The amount allowed on the return after applicable limits. |
| Tax saving | The effect of the deduction on federal income tax. |
| Withholding adjustment | A change in the timing and amount of tax paid through payroll. |
A practical midyear withholding check
- Gather current records. Have pay stubs for all household jobs, year-to-date federal income tax withheld, expected remaining wages and overtime, and relevant deduction information.
- Run the IRS estimator. Use its generated W-4 instructions to account for your full-year circumstances. Submit the completed form to your employer or payroll system.
- Review after payroll applies the change. Recheck when expected hours or household income change.
- Check again at the beginning of 2027. A midyear setting can be inappropriate for a full new year.

Common W-4 questions
Can I put all overtime in step 4(b)?
No. Gross overtime is not the qualified premium. Use the complete 2026 Deductions Worksheet, including its eligibility and income limits, or the IRS estimator. The completed worksheet total, not automatically your overtime amount, goes to step 4(b).
Why did my paycheck change by less than my annual estimated savings?
Ordinary periodic payroll calculations spread the effect of an annual step 4(b) amount over the annual payroll frequency. Entering an amount late in the year does not automatically deliver the entire annual effect over the remaining checks.
