What methods can employees use to calculate qualified overtime for their 2025 tax returns if employers don’t supply a separate overtime figure?
Executive summary
The IRS and Treasury issued Notice 2025-69 to help workers claim the new “qualified overtime” deduction for tax year 2025 even though employers are not required to separately report that amount on W-2s or 1099s for 2025 [1] [2]. The guidance lays out a set of “reasonable methods” taxpayers may use — relying on pay stubs, employer statements, simple formulas tied to FLSA time-and-a-half, and contemporaneous logs — and stresses a “reasonable effort” to determine FLSA eligibility and substantiate amounts [3] [4].
1. The problem: reporting lag and transition relief
Congress created an overtime deduction effective for 2025–2028 but the IRS postponed changes to standard information returns for the 2025 filing season, so Forms W-2 and 1099 generally will not separately identify qualified overtime or tips for 2025; Treasury/IRS provided transition relief and will not penalize employers for failing to separately report those amounts in 2025 [5] [3] [6].
2. The IRS’s overarching rule: make a reasonable effort and use reasonable methods
Notice 2025-69 tells taxpayers first to confirm whether they are FLSA-eligible employees and then, if no separate employer accounting is furnished, to use one of the IRS-approved “reasonable methods” to approximate the FLSA overtime premium for 2025 and support the deduction with documentation such as pay stubs or employer statements [4] [2] [7].
3. The practical toolbox: four core methods taxpayers can use
If a pay stub already breaks out an “overtime premium” (the half of time‑and‑a‑half), that listed premium may be used as the qualified overtime amount [1] [4]. Where a single “overtime” line aggregates pay, the IRS gives simple allocative formulas — for example, dividing aggregate overtime wages by 4 to extract the half premium in certain examples — and other methods based on known regular rate and overtime hours [1] [8]. Taxpayers may also rely on employer voluntary reporting in Box 14 of Form W‑2 or separate employer statements if provided [9] [7]. For employees with records of hours and regular rate, Method F allows calculation from regular rate and overtime hours worked over 40 in the workweek to compute the overtime premium [8].
4. How to document and substantiate the number you claim
The IRS explicitly permits pay stubs, earnings statements, daily tip logs, time records, payroll portals, and voluntary employer statements as evidence — the agency gives examples where daily tip logs or a payroll “overtime premium” line support the taxpayer’s chosen figure [1] [2] [4]. Notice 2025-69 makes clear taxpayers should preserve the contemporaneous records and any communications with employers because Forms W‑2/1099 may not show the separate amounts for 2025 [3] [10].
5. Tradeoffs, risks, and employer engagement
Although the IRS offers transition relief and explicit examples, taxpayers bear the burden to make a reasonable effort and could face questions on audit if calculations aren’t documented or are inconsistent with pay records; the guidance therefore encourages asking employers for voluntary breakdowns (Box 14 or separate statements) while recognizing many payroll systems won’t be updated until 2026 [6] [11] [10]. Alternative viewpoints from employer groups note operational burdens and variability in how compensatory time, state overtime rules, or premium pay interact with the federal FLSA-based definition of “qualified overtime,” meaning employees should confirm FLSA applicability when using the IRS methods [11] [12].
6. Bottom line: follow the IRS methods, document everything, and push for employer statements
For 2025 taxpayers may lawfully compute qualified overtime by using the IRS’s reasonable methods — direct overtime‑premium lines on paystubs, allocative formulas illustrated in Notice 2025-69, computations from regular rate and overtime hours, or voluntary employer reporting in Box 14 or separate statements — but must keep supporting records and make a demonstrable “reasonable effort” to determine FLSA eligibility and substantiation [2] [8] [9] [4].
