Box 12 of the Form W-2 carries a code this year that was not on the wage statement workers opened last January. Employers must now enter qualified overtime compensation there under the two-letter code TT, and that single entry is what makes the new overtime deduction usable at all. The Internal Revenue Service set out the mechanics in a fact sheet updated on Aug. 6, 2026, and several of them cut against what workers have been told to expect.
What code TT in box 12 actually reports
Qualified overtime compensation is a narrower thing than overtime pay. It is only the portion of overtime required under section 7 of the Fair Labor Standards Act that exceeds an employee’s regular rate, which is the “half” inside time-and-a-half. An employer that pays double time on its own initiative reports only the amount the FLSA itself required, not the extra it chose to add.
That figure now has a mandatory home on the wage statement. Fact Sheet FS-2026-13, which the agency announced on Aug. 6, states that starting in tax year 2026, payors and employers are required to separately report qualified overtime compensation on Form 1099-MISC box 14, Form 1099-NEC box 1d, or, more commonly, Form W-2 box 12, code TT. The statements carrying those entries reach households in January 2027 and cover wages paid during 2026.

The $12,500 ceiling and the $150,000 line where it starts shrinking
The deduction runs up to $12,500 of qualified overtime compensation earned for the year on an individual return, and up to $25,000 on a joint return. It is available whether a filer itemizes or takes the standard deduction, which puts it within reach of the large majority of wage earners who never itemize anything.
Higher earners see the amount come down rather than vanish. The IRS says the deduction is reduced once modified adjusted gross income exceeds $150,000, or $300,000 for joint filers. Reduced is the operative word there. Two other conditions are absolute: the employee must have a Social Security number valid for employment, issued before the return’s due date including extensions, and a married employee must file a joint return with a spouse to claim anything at all.
Schedule 1-A does the arithmetic, not the wage statement
The amount printed in box 12 is the total qualified overtime paid, and the agency is blunt that it is not necessarily the deductible amount. Its own example describes an employer that paid $30,000 of qualified overtime during 2026. All $30,000 goes in box 12, code TT, even though the overall limit on the deduction is $12,500, or $25,000 on a joint return.
The reconciliation happens on the return. An employee carries the full box 12 figure to Part III of Schedule 1-A (Form 1040), then completes the rest of Part III, which applies the cap and the income phase-down. Whatever lands on the last line of Part III is the deduction. Anyone reading the box 12 number as a refund preview is reading the wrong line.
Withholding does not fall, so the money arrives at filing
This is the part most likely to disappoint a household counting on bigger checks. Overtime pay is generally not excluded or exempted from wages for employment tax purposes, including income tax withholding, Social Security and federal unemployment taxes. The IRS states plainly that an employer may not reduce withholding on wages to account for the qualified overtime deduction.
There is one exception, and it requires paperwork from the employee. An employer may lower withholding if the worker furnishes an updated and valid Form W-4 that accounts for the expected deduction. The 2026 version of that form was revised so the figure can be entered in step 4(b), and the agency’s Tax Withholding Estimator was updated for the same purpose. A worker who files nothing new still gets the deduction. It simply shows up as a smaller balance due or a larger refund at filing rather than as a fatter paycheck in the meantime.
Which workers are FLSA overtime-eligible in the first place
The deduction reaches only employees who are covered by the FLSA and not exempt from its overtime requirement. Executive, administrative and professional employees sit outside it, as do outside sales staff, employees in certain computer-related occupations, some commissioned workers at retail and service establishments, taxi drivers, seamen on American vessels and certain motor carrier employees. An employee who owns at least a bona fide 20 percent equity interest in the enterprise and is actively engaged in managing it is treated as a bona fide executive, and therefore ineligible.
Overtime that an employer pays voluntarily, under a state law, or under a collective bargaining agreement does not become qualified overtime compensation simply because it is called overtime. The test is whether section 7 of the FLSA required the payment, and only the amount minimally necessary to satisfy that requirement counts toward the deduction.
No entry in box 12 means no deduction, even if the overtime was real
Section 225(a) of the Internal Revenue Code allows the deduction only for qualified overtime compensation that an employer included on a properly furnished Form W-2. Relief that applied to tax year 2025 let employees claim amounts their wage statement never showed. No such relief exists for years after 2025.
The consequences are asymmetric and worth knowing before January. If an employer omits or understates the figure, the employee must request a corrected Form W-2c, and if the employer will not or cannot issue one, the omitted amount is simply unusable. A substitute wage statement on Form 4852 does not satisfy the statute. If an employer overstates the figure, the employee may still count only the qualified overtime actually paid. Either way, the box 12 line on the statement that arrives in January is the document that decides the size of the deduction.
