What Actually Counts as Qualified Overtime (and What Your Pay Stub Will Not Tell You)

"No tax on overtime" is the least accurate nickname in the 2025 tax law. The deduction does not exempt overtime from tax, it does not cover your overtime pay, and for a large number of people who work overtime it does not apply at all.

Everything turns on one clause. Qualified overtime compensation is overtime required under section 7 of the Fair Labor Standards Act that exceeds the regular rate at which the individual is employed. Both halves of that sentence disqualify money.

Only the premium, not the pay

The 2026 Form W-2 instructions put it in one line: "only the 'half' portion of 'time-and-a-half' compensation would be reported using code TT."

Work an overtime hour at $30 when your regular rate is $20 and the qualified amount is $10, not $30. The first $20 is ordinary wages you would have earned anyway; only the FLSA-required premium on top is the thing the statute is talking about.

Your pay stub almost certainly does not present it that way. An "OT" line typically shows hours times the overtime rate — the whole $30. Getting from that to the deductible figure means separating the premium out, every period, for the year.

This is the single most likely reason a Box 12 code TT figure on a 2026 W-2 will look wrong. For pure time-and-a-half work the premium is exactly one third of the overtime line, because the premium is half the regular rate and the overtime pay is one and a half times it. If code TT resembles the whole overtime line instead, that is a conversation with payroll before you file.

If the FLSA does not require it, it does not count

This is the part that catches whole categories of workers.

The IRS is direct: "An individual who is ineligible for overtime under the FLSA does not receive qualified overtime compensation regardless of other laws or circumstances (such as a collective bargaining agreement) providing for overtime pay."

So the following are not qualified overtime:

• Overtime paid only because state law requires it. A state daily-overtime rule that pays a premium after eight hours in a day, where no FLSA obligation exists, produces nothing deductible.
• Overtime paid under a union contract that goes beyond what section 7 requires.
• Weekend or holiday premiums paid as a matter of policy rather than because the FLSA compelled them.
• Anything paid to an employee who is exempt from the FLSA in the first place, however their employer chooses to compensate extra hours.

Notice 2025-69 works through this with an example that surprises people: if an employer chooses to pay double time for hours over 40, "while the additional one-half times portion required by the FLSA may be qualified overtime, payments in excess of the FLSA-required premium are not." Generosity above the statutory floor is not deductible. Only the floor is.

There are FLSA structures that change the shape of the calculation without changing the principle. Section 207(k) lets fire protection and law enforcement overtime be measured over a work period longer than a standard 40-hour week. Section 207(j) lets hospitals and certain residential care facilities agree to pay time-and-a-half for hours over eight in a day or over 80 in a 14-day period. Those are still FLSA-required overtime.

The same dollar cannot be a tip and overtime

Section 225(c)(2) excludes qualified tips from the definition of qualified overtime. If you work in a tipped occupation and your overtime hours generated tips, those tips belong in Part II of Schedule 1-A, not Part III. They cannot be counted in both places, which is worth checking if you are reconstructing figures by hand.

What the deduction is worth, before you get excited

The cap is $12,500, or $25,000 on a joint return — and the Form 1040 instructions note that the joint figure "is not a per spouse limit." Two spouses share it.

It is reduced by $100 for each whole $1,000 of modified AGI above $150,000 ($300,000 joint). Schedule 1-A line 19 rounds those thousands down, so partial thousands cost nothing.

You need a Social Security number valid for employment, and if you are married you must file jointly. Married filing separately is excluded outright.

And this is a deduction against taxable income, not a credit and not a refund of withholding. Overtime compensation remains "subject to federal income tax withholding and both the employer share and employee share of social security tax and Medicare tax." Nothing about your paycheck changes; the adjustment happens on Schedule 1-A when you file.

The deduction is available for tax years beginning after December 31, 2024 and ending before January 1, 2029 — 2025 through 2028.

Why the pay stub is the right place to work this out

The 2026 Form W-2 arrives by February 1, 2027 with a code TT figure on it. By then the year is closed and there is nothing left to decide.

Right now, mid-year, three things are still moveable.

Whether the premium is separately visible. If your employer's stubs do not break out the FLSA premium, they will have to derive it for the W-2 anyway. Asking now is cheaper than discovering the number in February.

Whether you are near a phaseout step. Modified AGI drives all four Schedule 1-A deductions at once. If yours will land just over a $1,000 boundary above $150,000, the timing of discretionary income matters at the margin.

Whether your overtime is FLSA overtime at all. If it is not, the deduction is not a plan, and it is better to know that in August than in April.

What to do with your next stub

1. Find your regular rate, not your overtime rate. The premium is the difference.
2. Check whether the stub separates the premium. If it shows only an OT total, ask payroll how they intend to populate code TT.
3. Confirm you are FLSA non-exempt. If you are exempt, no amount of overtime pay is qualified overtime.
4. Separate any tips out. They belong in a different part of Schedule 1-A.
5. Project YTD to December and run it against the $12,500 cap and your expected MAGI before you count on anything.

Our free tips and overtime deduction projector does that last step — it takes the year-to-date figures off a stub, projects them to December, and shows the deduction you are on track for after the cap and the phaseout. The Schedule 1-A estimator stacks it against the other three deductions, and the guide to the new Box 12 codes covers what will land on the W-2 in February.
