“No tax” means a deduction—not tax-free wages
Qualified overtime compensation can create a federal income-tax deduction for tax year 2026. The underlying overtime wages are still wages. They remain on the pay stub, still count toward income, and remain subject to Social Security and Medicare taxes. The deduction is applied separately when federal income-tax liability is determined.
This distinction matters because a worker can receive $15,000 of total overtime pay without having $15,000 of qualified overtime compensation. The potentially qualified figure is the premium required by the Fair Labor Standards Act, subject to the IRS rules—not every dollar earned during overtime hours.
For time-and-a-half, focus on the extra 0.5×
Suppose the regular rate is $30 per hour. One overtime hour paid at time-and-a-half produces $45: a $30 regular-rate portion plus a $15 overtime premium. The $15 premium is the starting point for the federal qualified-overtime calculation when the payment is required under the FLSA.
If the employee works eight qualifying overtime hours per week for 48 weeks, total overtime pay is $17,280. The estimated FLSA premium is $5,760: $30 × 0.5 × 8 × 48. Double-time, daily overtime, a union premium or an employer's voluntary overtime policy can produce more pay, but the amount above the federally required premium does not qualify merely because it appears as overtime.
The eligibility question comes before the math
The calculator cannot decide whether a worker is non-exempt, whether particular hours exceeded the FLSA weekly threshold, or whether another federal exception applies. Before claiming the deduction, confirm why the overtime was required and how payroll classified the premium.
- Confirm the employee and hours are covered by the FLSA overtime requirement.
- Separate the federally required premium from state-only, contract-only or voluntary extra pay.
- Use the employer-reported 2026 qualified amount when a reliable W-2 or payroll record is available.
- Do not add a personal estimate to the same employer-reported amount.
2026 caps and the MAGI phaseout
The starting annual cap is $12,500 for an individual return and $25,000 for married filing jointly. The phaseout begins when modified adjusted gross income exceeds $150,000 on an individual return or $300,000 on a joint return. The cap falls by $100 for each complete $1,000 above the applicable threshold.
For example, an individual with $180,000 of MAGI is $30,000 above the threshold. Thirty complete $1,000 increments reduce the $12,500 cap by $3,000, leaving a maximum of $9,500 before comparing the cap with actual qualified overtime. The permitted deduction is the smaller of qualified overtime compensation and the remaining cap, never less than zero.
Tax savings are smaller than the deduction
A deduction reduces taxable income; it is not a dollar-for-dollar credit. A $5,760 deduction at an assumed 22% marginal federal income-tax rate has an estimated value of $1,267. The exact result can differ if the deduction crosses a tax bracket or other items change the return.
The calculator asks for a marginal rate so it can keep this assumption visible. It does not represent the estimate as an IRS-calculated refund and does not include state income-tax treatment.
Paycheck withholding and the tax return are two timings
The new deduction does not automatically tell an employer to withhold less. On the 2026 W-4 Deductions Worksheet, line 1b accepts estimated qualified overtime only when total income is below $150,000, or $300,000 when married filing jointly. At or above the threshold, use the IRS Tax Withholding Estimator or follow the worksheet instructions rather than placing the overtime amount directly on the form.
Step 4(b) is not the overtime deduction. It receives Deductions Worksheet line 15—the final amount after qualified overtime and the taxpayer's other permitted deductions are combined. Publication 15-T tells employers how to apply that completed Form W-4 to federal income-tax withholding. A per-paycheck estimate is therefore a planning figure, not a promise of the next deposit.
If no valid W-4 change is made, automatic withholding change is zero; the eligible annual deduction may instead affect the federal return. Lower withholding and the return result describe the same annual tax benefit, so they must not be added together.
Check W-2 Box 12, Code TT
For 2026 reporting, employers use Box 12 Code TT to separately report qualified overtime compensation. This gives workers and tax preparers a specific record to compare against hours and pay statements. A missing or unexpected amount is a reason to contact payroll, not a reason to invent an amount at filing time.
A practical 2026 checklist
- Collect pay stubs showing regular rate, overtime hours and overtime premium.
- Confirm the overtime was required by the FLSA.
- Estimate the 0.5× premium or use a verified Code TT amount.
- Apply the filing-status cap and MAGI phaseout.
- Estimate federal income-tax savings separately from FICA.
- Use Form W-4 only if you want payroll to reflect the expected deduction during the year.
- Reconcile the estimate to W-2 Box 12 Code TT before filing.
