How do employees calculate the deductible 'qualified overtime' amount from year-end payroll records?

1. What the law actually allows employees to deduct

The deduction applies only to the FLSA‑required premium portion of overtime—the “half” over an employee’s regular rate that makes overtime pay time‑and‑a‑half—and only for overtime that meets FLSA weekly overtime rules (hours over 40 in a workweek), not ordinary wages or non‑FLSA overtime premiums imposed by state or local rules ^{[1] [7] [8]}.

2. Where that number might appear on payroll documents

Employers are encouraged to furnish a separate accounting of qualified overtime either in Box 14 of Form W‑2 or on a separate statement; if provided, employees may rely on that employer‑supplied figure to claim the deduction ^{[2] [3]}. For tax year 2025 the IRS granted a relief period so employers won’t be penalized if they fail to separately report qualified overtime, meaning many workers will need to compute the amount themselves from other payroll records ^{[6] [9]}.

3. What payroll records to gather before computing

Taxpayers should collect year‑end earning statements, pay stubs, payroll summaries, timecards showing weekly hours, and any employer statements of “overtime” or “overtime premium”; the IRS guidance and tax providers specifically list these documents as acceptable sources for reconstructing qualified overtime when Box 14 data is absent ^{[2] [10] [3]}.

4. The reasonable‑method approach the IRS permits

When an employer does not supply the qualified‑overtime amount, the IRS allows employees to use a “reasonable method” to determine the FLSA overtime premium from available records—examples in IRS Notice 2025‑69 show reconstructing the premium from total overtime pay and known pay practices, and tax guidance gives permitted allocation approaches (for example, dividing total overtime gross by three to extract the half‑time premium in certain rate structures) ^{[5] [4] [3]}.

5. A simple step‑by‑step calculation pattern

Start with weekly or year‑to‑date overtime gross and total overtime hours, confirm the regular hourly rate and the overtime rate paid, compute the premium per overtime hour as (overtime rate − regular rate) which for standard time‑and‑a‑half equals 0.5 × regular rate, multiply that premium by overtime hours to get qualified overtime compensation, and sum weekly amounts or use a consistent year‑to‑date allocation if payroll shows only aggregate overtime pay; the IRS examples and employer guides use this half‑time × overtime‑hours formula and demonstrate extracting the premium from aggregate overtime when necessary ^{[11] [1] [5]}.

6. Practical tools, state exceptions and recordkeeping risks

Payroll systems and tax software are updating to automate qualified‑overtime tracking and some vendors provide calculators or payroll‑item fields to capture the half‑time premium, but employees should be careful about state/local overtime rules (daily overtime or different thresholds) because such non‑FLSA overtime does not qualify for the federal deduction and must be excluded when reconstructing the federal qualified amount ^{[1] [12] [8] [7]}.

7. Bottom line for claimants

Employees can claim the deduction by using employer‑provided Box 14 or separate statements when available, and otherwise by applying a reasonable, documented method that isolates the FLSA half‑time premium from year‑end payroll totals and time records; keep those supporting pay stubs and calculations with tax records because the 2025 IRS guidance permits reconstruction now but anticipates clearer employer reporting in future years ^{[2] [3] [6]}.
