IRS overtime FAQs show where 2027 filing season could stall

Tax pros preparing 2026 returns will encounter a new entry on some clients’ Forms W-2: Box 12, Code TT. That number identifies qualified overtime compensation, but it is not automatically the amount the taxpayer can deduct. A missing or understated entry may also prevent the taxpayer from claiming the deduction until the employer issues Form W-2c, Corrected Wage and Tax Statement.

The IRS addressed these filing-season issues in FS-2026-13, which supersedes the qualified overtime FAQs issued in January. The updated fact sheet expands the guidance from eight questions to 32 and replaces much of the 2025 transitional guidance. The FAQs add detailed guidance that will affect how tax pros handle the deduction when 2026 Forms W-2 and 1099s arrive.

OT FAQs quick take

Beginning with 2026 information returns, tax pros should confirm that qualified overtime was separately reported, determine whether the worker and compensation qualify under the Fair Labor Standards Act (FLSA), and know when a corrected form is required. Box 12, Code TT, is only the starting point for the review.

Code TT brings qualified overtime onto the return

Employers must separately report qualified overtime compensation on Form W-2, Wage and Tax Statement, Box 12, using Code TT. Certain payers may instead report the amount on Form 1099-MISC, Miscellaneous Information, Box 14, or Form 1099-NEC, Nonemployee Compensation, Box 1d.

The employer reports the full amount of qualified overtime compensation. The employer does not reduce the reported amount based on the taxpayer-level deduction limits. The deduction is capped at $12,500, or $25,000 for a joint return, and may be further reduced by the modified adjusted gross income phaseout. Those limitations are applied when the individual return is prepared.

For employees, qualified overtime also remains included in wages and subject to federal income tax withholding and employment taxes. An employer does not automatically reduce withholding because an employee may qualify for the deduction. Employees who want the expected deduction reflected in their withholding may submit an updated Form W-4, Employee’s Withholding Certificate, using the deduction worksheet in Step 4(b).

➙ Clients have heard “no tax on overtime” and may expect the entire amount to be excluded from taxable wages on their paystubs. You can advise them that it is not processed this way; the tax benefit is claimed as an individual income tax deduction.

FLSA status controls how much overtime qualifies

An amount labeled “overtime” on a paystub does not automatically qualify for the deduction. Generally, only the premium required under Section 7 of the FLSA, the amount paid above the employee’s regular rate, is qualified overtime compensation.

➙ For example, assume an employee’s regular rate is $20 per hour and the employer pays $40 for an overtime hour. The FLSA generally requires time and one-half, or $30. Only the $10 premium required above the regular rate is qualified overtime compensation. The additional $10 paid voluntarily by the employer does not qualify.

The updated FAQs add extensive guidance addressing FLSA exemptions, employee-owners, alternative overtime calculations and special work periods. State law or contractual overtime may not qualify unless the payment is also required under the federal FLSA rules. The same is true of an employer-paid premium that exceeds the FLSA requirement.

Preparers should question an amount that appears to include the employee’s regular wages for overtime hours rather than only the federally required premium. They should also pause when the client is an exempt employee or works under an unusual pay arrangement.

An incorrect W-2 may interrupt return preparation

The correction rules may create the biggest filing-season problem.

When qualified overtime is omitted or understated, the employee must request Form W-2c from the employer. The IRS FAQs state that Form 4852, Substitute for Form W-2, cannot be used to provide the employer’s required separate reporting of qualified overtime compensation.

That leaves the preparer with a return-management decision. Depending on the timing and the client’s circumstances, the taxpayer may need to delay filing until Form W-2c arrives or request an extension. If the taxpayer files without the deduction, an amended return may be needed after the corrected form arrives.

An overstated Code TT amount should not simply be transferred to the return either. The taxpayer is entitled to consider only the qualified overtime compensation actually received, and the employer should correct the reporting error.

The FAQs help explain how the IRS plans to administer the deduction, but they are not published guidance that controls a taxpayer’s legal position. FS-2026-13 states that the FAQs generally cannot be relied on to resolve a case, although reasonable, good-faith reliance may support relief from certain penalties.

Qualified overtime filing-desk check

Tax firms can prepare now by adding Code TT to organizer reviews and training staff not to treat the reported amount as a direct-entry deduction. When a questionable number lands on the desk, identifying the reporting problem early may prevent a rushed correction decision near the filing deadline.
