How to Report Qualified Overtime on the 2026 W-2 — and Catch What Your Payroll System Misses

If you run payroll for a Houston business with hourly or other overtime-eligible staff, the 2025 budget law gave you a new number to put on every W-2: "qualified overtime compensation," the pay behind the "no tax on overtime" deduction. The short version for an operations or finance lead is that you report only the FLSA overtime premium — the "half" of time-and-a-half — not the whole overtime check, and starting with 2026 it goes in a specific box. The part that will actually trip you up is not the box. It is whether your payroll system computed that premium on the right wage figure.

This article covers what you have to report, why the regular-rate calculation is where the number goes wrong, and a reconciliation you can run once a year to catch it before the W-2s go out. It is written for the employer doing the reporting, not for the worker claiming the deduction. It is also a different question from who is exempt from overtime in the first place, which turns on a rising salary threshold and is covered separately.

What you actually have to report

Qualified overtime compensation is the overtime pay required by the Fair Labor Standards Act that exceeds an employee's regular rate — the premium portion, not the full time-and-a-half payment (IRS). The deduction itself is capped at $12,500 per return ($25,000 on a joint return), phases out once modified adjusted gross income passes $150,000 ($300,000 for joint filers), and is in effect only for tax years 2025 through 2028 (University of Illinois Tax School). It is a deduction, not an exclusion: the overtime is still part of the employee's gross income and still subject to payroll taxes (IRS).

For 2025, separate reporting was optional — an employer could show the amount in box 14 of the W-2, on a separate statement, or through an online portal (IRS). That grace period is over. Under the IRS's updated August 2026 guidance, employers must report qualified overtime on Form W-2 in Box 12, code TT, beginning with 2026, and must report the full qualified overtime paid for the year even when the employee cannot deduct all of it; an error has to be fixed with a Form W-2c (Journal of Accountancy). An employee generally can claim the deduction only for an amount the employer reports, so a figure that is missing or too low costs the worker money and can expose the employer to information-return penalties.

Why the regular rate is where it breaks

The reportable number is only as good as the regular rate behind it, and that is where most payroll setups go wrong. Under the FLSA, overtime is one and one-half times the employee's regular rate for hours worked over 40 in a workweek, and the regular rate is not just the base hourly wage: it includes almost all remuneration for employment — nondiscretionary bonuses, shift differentials, and the like — divided by the hours worked. Only truly discretionary bonuses and a short list of gifts may be left out (U.S. Department of Labor). Qualified overtime is the half-rate premium on that regular rate, so if the regular rate is understated, so is the premium you pay and the number you report.

Illustrative example: a Houston distribution company pays a warehouse picker $24.00 an hour. In one week she works 48 hours and earns a $120 attendance bonus she was promised in advance for perfect attendance, which makes the bonus nondiscretionary and part of the regular rate. Her regular rate that week is all of her straight-time pay plus the bonus, divided by the hours she worked: 48 hours times $24.00 is $1,152.00, plus the $120.00 bonus is $1,272.00, divided by 48 hours is $26.50 an hour. The overtime premium she is owed — and the qualified overtime to report — is the extra half-rate on her 8 overtime hours: 0.5 times $26.50 times 8 equals $106.00 for the week. A payroll setup that computes overtime on her $24.00 base rate and ignores the bonus produces 0.5 times $24.00 times 8, or $96.00 — $10.00 short that week. Over a year of similar weeks the gap compounds, and it is short on two things at once: the overtime wages she is actually owed under the FLSA, and the figure in Box 12, code TT.

That second point matters more than the tax line. Getting the regular rate wrong is first a wage problem, an underpayment of overtime, and only second a reporting problem. The fix for both is the same: compute the premium on the correct regular rate.

A reconciliation you can run once a year

Most payroll platforms now carry a qualified-overtime field and will populate Box 12, code TT. The useful work for your team is not turning that feature on; it is checking that the number it produces is built on the right regular rate. This is a method for organizing the check, not legal or tax advice. Run it once, before W-2s are finalized:

1. Pull, for each nonexempt employee, the full year's worked hours by workweek and every pay component in each week — base wages, nondiscretionary bonuses, shift differentials, commissions, and any other pay that is not statutorily excludable.
2. For each workweek with more than 40 hours, recompute the regular rate (total non-excludable pay divided by hours worked) and the FLSA premium (half the regular rate times the overtime hours). Sum those premiums across the year for that employee.
3. Compare your recomputed total to the amount payroll flagged as qualified overtime for Box 12, code TT. Flag every employee whose two figures differ by more than a small rounding tolerance.
4. Route each flagged case to a person — a payroll lead or compensation counsel — to find the cause (a bonus left out of the regular rate, a discretionary-versus-nondiscretionary call, a worker paid two rates, or state-only overtime the FLSA does not require) and decide the correction.

This is the kind of check automation handles well: pulling hours and pay components from the payroll and timekeeping systems, recomputing each week's regular rate, and surfacing the employees whose reported figure does not match. What it cannot do is make the judgment calls — whether a bonus was truly discretionary, how to treat a worker paid two rates, whether an exposure needs a corrected filing. Those stay with a person, and a flag is not a finished answer until someone owns each one and records what was done. Because the deduction runs through 2028 and the regular-rate rule does not change, it is worth building the reconciliation once and rerunning it each December rather than rediscovering the edge cases every year.

What this means for a Houston employer

Two things make this sharper in Houston than the federal headline suggests. Texas has no overtime law of its own, so the FLSA is the whole standard here — time and one-half over 40 hours in a workweek, with no daily-overtime rule like California's — which means the qualified overtime you isolate is simply the premium you already owe, with no separate state-only overtime to carve out. And because Texas has no personal income tax, the deduction is a purely federal benefit for your workers, one they can claim only if the number on their W-2 is right. The reporting job lands entirely on you, and a wrong figure is corrected only with a Form W-2c (Journal of Accountancy). The same logic applies to a Seattle, Chicago, or Dallas employer whose state likewise follows the federal 40-hour rule.

So the order of work is straightforward: confirm your payroll system is flagging qualified overtime and reporting it in Box 12, code TT; reconcile that figure against a clean regular-rate recomputation before the W-2s go out; then fix any gaps as wage corrections first and reporting corrections second. The deduction is the worker's to claim. Reporting the number accurately is yours.
