OBBBA W-2 Reporting Guide for Employers
The No Tax on Overtime and No Tax on Tips deductions created new W-2 reporting obligations. This guide explains what employers need to do for tax years 2025 through 2027, including the finalized box codes, correction procedures, and penalty rules.
The Two Reporting Periods
Tax Year 2025 (Transition Period)
- Employer W-2 reporting was optional — the IRS did not update the 2025 W-2 for the new boxes
- Notice 2025-69 gave employees a way to compute the deduction from pay stubs, payroll statements, or daily tip logs
- Notice 2025-62 provided penalty relief for 2025 information reporting
- Employees claim the 2025 deduction on Schedule 1-A using their own substantiation
Tax Year 2026 (Mandatory Reporting)
- W-2 reporting becomes mandatory; W-2s are due February 1, 2027
- Box 12 code TT: total qualified overtime compensation (premium portion only)
- Box 12 code TP: total cash tips reported to the employer
- Box 14b: Treasury tipped occupation code(s) — "000" alone means tips do not qualify
- Employees may only deduct amounts that actually appear in box 12 codes TT/TP
- Errors require a Form W-2c; incorrect filings risk penalties under sections 6721/6722
The 2026 Form W-2, Box by Box
| Location | What Goes There |
|---|---|
| Box 12, code TT | Total qualified overtime compensation — the FLSA-required premium portion in excess of the regular rate, determined workweek by workweek |
| Box 12, code TP | Total amount of cash tips the employee reported to the employer |
| Box 12, code TA | Employer contributions to an employee's (or dependent's) Trump account — new for 2026, unrelated to the OT/tips deduction |
| Box 14a / 14b | 14a keeps the old "Other" box; 14b holds up to two Treasury tipped occupation codes |
What Counts as "Qualified" Overtime?
Not all overtime pay qualifies for the deduction. The IRS defines qualified overtime as:
- Overtime compensation required by the FLSA — pay for hours beyond 40 in a workweek, at not less than one-and-a-half times the regular rate
- Only the premium portion in excess of the regular rate is reported in code TT ($10/hour employee: $15 OT rate, $5/hour reported)
- Paid to an employee non-exempt under the FLSA
- Determined workweek by workweek, using the FLSA regular-rate rules (which include most bonuses and shift differentials in the base)
Does not qualify: Bonuses, commissions, on-call pay, or premium pay not tied to FLSA hours beyond 40 — and comp time at state/local government agencies is treated separately (the IRS example covers compensatory time at 1.5× hours).
What Counts as "Qualified" Tips?
Qualified tips must meet these criteria:
- Cash tips received in an occupation that customarily and regularly received tips on or before December 31, 2024
- Reported to the employer (section 6053(a) statement or the employer's tip reporting system) — unreported cash tips never qualify
- Subject to FICA tax (Social Security and Medicare)
- Capped at $25,000 per individual per year, regardless of filing status
Tips received during overtime hours count toward the tips deduction, not the overtime deduction. Mandatory service charges (autograt) are wages, not tips. Box 12 code TP reports the tips; Box 14b reports the Treasury occupation code that determines whether they qualify.
When Things Go Wrong: W-2c and Penalty Rules
Employer discovers an error in code TT/TP
File Form W-2c with the SSA and furnish it to the employee as soon as possible. Timely corrections qualify for reduced penalties under sections 6721/6722; uncorrected incorrect filings face the full amounts, which escalate by size of the business and lateness.
Employee says the box 12 amount is too low
From 2026, the employee can only deduct what is reported in box 12 code TT/TP. The IRS FAQ is explicit: they must obtain a W-2c from the employer, and a substitute Form 4852 cannot be used to claim additional qualified overtime. If the employer will not correct it, the reported number stands.
The reported amount exceeds the deduction caps
Not an error. Employers report the full qualified amount even when it exceeds the $12,500/$25,000 deduction limits or the employee's income phase-out — the IRS example reports $30,000 in code TT. The caps are applied on the employee's Schedule 1-A. But an amount that overstates what was actually paid is wrong; the employee uses the true amount, not the box number.
Employer Action Checklist
| When | What to Do |
|---|---|
| Tax year 2025 | No W-2 changes required. Employees self-substantiate via pay stubs and tip logs under Notice 2025-69 relief. |
| During 2026 | Update payroll to track qualified OT premium workweek by workweek and reported cash tips. Map each tipped role to its Treasury occupation code for Box 14b. |
| Jan–Feb 2027 | Issue W-2s with box 12 TT/TP and box 14b populated. Due February 1, 2027. |
| After filing | If errors surface, file and furnish Form W-2c promptly to lock in reduced penalties. |
Common Employer Confusion
“Do I need to withhold less tax?”
No. The deduction is claimed on the employee's tax return, not at the payroll level. Employers continue normal withholding; employees who want smaller paychecks-to-refund gaps can adjust their own W-4.
“What about salaried employees?”
Only FLSA overtime-eligible employees who actually receive overtime pay qualify. Salaried exempt employees do not receive FLSA overtime and cannot claim the deduction. The rare edge case — an FLSA employee treated as a contractor for tax purposes — reports on Form 1099-MISC box 14 or 1099-NEC box 1d instead of a W-2.
“What about state taxes?”
The OBBBA deductions are federal only. States that do not conform (California and Pennsylvania among them) tax the overtime and tip income normally at the state level even though it is deductible federally.

Frequently Asked Questions
When do employers need to start reporting overtime and tips on W-2s?
For tax year 2025, employer reporting on the W-2 was optional under transition relief (IRS Notice 2025-69, with penalty relief under Notice 2025-62). Starting with tax year 2026 — W-2s due February 1, 2027 — reporting qualified overtime pay and tips in the dedicated boxes is mandatory, and the 2025 relief will not be repeated.
Which W-2 box shows qualified overtime pay?
Box 12, code TT. The 2026 Form W-2 finalized this: TT reports the total qualified overtime compensation, which is the premium portion only — the amount in excess of the employee's regular rate required by the FLSA. Example from the IRS: a $10/hour employee has a $15 overtime rate, and the $5 premium per OT hour is what goes in code TT. Code TP reports total cash tips reported to the employer.
What happens if an employer doesn't report overtime for 2025?
Nothing, under the transition rule. Notice 2025-69 lets employees claim the deduction for 2025 using their own pay records, daily tip logs, or a payroll statement showing the overtime premium. But from 2026 onward, employees may only deduct amounts that appear on Form W-2 box 12 code TT — and non-reporting or understatement can trigger information reporting penalties under sections 6721 and 6722.
The employer reported the wrong amount in code TT. Can the employee fix it?
Only through the employer. If the box 12 code TT amount is understated or omitted, the employee must request a Form W-2c from the employer — the IRS has explicitly ruled that a substitute Form 4852 cannot be used to claim additional qualified overtime. If the employer refuses or is unable to correct it, the employee is stuck with the amount as reported. Employers who discover errors themselves must file and furnish a W-2c as soon as possible; timely corrections qualify for reduced penalties.
What if code TT shows more than the employee can actually deduct?
That is expected, not an error. The employer reports the total qualified overtime compensation paid, even though the employee's deduction is capped at $12,500 ($25,000 on a joint return) and phased out by income. The IRS example: an employer who paid $30,000 of qualified overtime still reports $30,000 in box 12 code TT. The employee applies the caps on Schedule 1-A. The one exception: if the reported number is simply wrong (overstates what was actually paid), the employee may only use the true amount.
What is Box 14b, the Treasury tipped occupation code?
Box 14 on the 2026 W-2 was split into 14a (the old 'Other' box) and 14b, where employers report up to two Treasury-issued tipped occupation codes identifying whether the employee's role qualifies for the tips deduction. The codes work together with box 12 code TP: code '000' by itself means the employee's tips are not eligible for the OBBBA tip deduction. The Treasury occupation list was due October 2, 2025, per the statute.
