No Tax on Overtime: What the OBBB Deduction Actually Means for Employers
Quick-read version · 1 min"No tax on overtime" does not make an overtime check tax-free.
For employers, the new rule is narrower than the headline. It creates a federal income-tax deduction for the extra half of FLSA overtime — the premium portion of time-and-a-half — not the full overtime check, not Social Security or Medicare tax, and not most state income tax.
The employee claims the deduction on their tax return. The employer's job is to report the right number.
For tax year 2026 (W-2s issued January 2027), that number goes in Box 12 code TT: "Total amount of qualified overtime compensation." If your payroll system reports the full 1.5× overtime check, includes California daily overtime that does not qualify, or folds in policy "overtime" paid to exempt employees, it can inflate the deduction on every affected W-2. Penalties under IRC § 6721 and § 6722 for incorrect information returns are $310 per form, capped at $3.78M per year per employer (2026 figures).
The fiscal stakes are large. The Joint Committee on Taxation scored the OBBB no-tax-on-overtime + no-tax-on-tips package at approximately $121 billion in foregone federal revenue over the 10-year budget window (FY2025–2034) — roughly $89 billion attributable to the overtime deduction, ~$32 billion to the tips deduction. The Tax Policy Center estimates approximately 17 million filers will benefit from the overtime deduction. Treasury and the IRS are now policing those deductions through information-return accuracy.
Quick reference
- What's deductible: the FLSA premium (the 0.5× in time-and-a-half) on hours over 40 per workweek. Not the full 1.5× overtime check.
- Who qualifies: FLSA-nonexempt employees with valid SSN. Independent contractors, FLSA-exempt employees, and recipients of state-only overtime do not.
- Annual cap: $12,500 (single) / $25,000 (joint return). Below-the-line deduction on new Schedule 1-A (line 13b of Form 1040); reduces taxable income, not AGI. Available whether the taxpayer takes the standard deduction or itemizes.
- MAGI phase-out: deduction reduced by $100 per $1,000 of MAGI above $150,000 (single) / $300,000 (joint). Fully phased out at $275,000 / $550,000.
- Effective: tax years 2025–2028. Sunsets December 31, 2028 absent extension.
- Employer reporting: voluntary in 2025 W-2 Box 14; mandatory in 2026 W-2 Box 12 code TT.
- Where the federal deduction currently lowers state taxable income: Oregon, Idaho, North Dakota, and South Carolina. Most other states either start from federal AGI, have no wage income tax, use their own tax base, or have added the federal deduction back.
The 5 Most Expensive Misconceptions
-
"No tax on overtime" is not no tax. The deduction is the FLSA premium only — the extra 0.5× in time-and-a-half. On an employee earning $20/hr regular and $30/hr OT, only the $10/hr premium is deductible, not the full $30. FICA (Social Security + Medicare) is still owed on the full overtime check. State income tax may also still apply. Employees who saw the headline may expect tax-free overtime checks; communicate the filing-time benefit clearly before W-2 season.
-
California, Washington, and other state-daily-overtime states get less. California's daily 8-hour overtime, daily double-time, and 7th-consecutive-day premium do not qualify under § 225(c) — the statute restricts qualifying overtime to "section 7 of the Fair Labor Standards Act," which is the federal weekly 40-hour rule only. California's ~18 million-worker non-farm workforce (per CA EDD) includes the largest concentration of state-daily-overtime exposure in the country; a CA worker who racks up state-daily-OT but only modest FLSA-weekly-OT sees little federal deduction benefit. Combine with California's state-level non-conformity (~$3.2B/year revenue protected by SB 711's pre-OBBB conformity-date cutoff) and the practical benefit can be near-zero for the workers the headline was supposedly aimed at.
-
CBA premiums and policy "overtime" don't qualify. If your collective bargaining agreement requires 1.5× on hours over 8/day, 2× on Sundays, or 1.5× on holidays — none of that qualifies for the federal deduction unless it also happens to coincide with FLSA-required hours-over-40 overtime. Similarly for any employer-policy "overtime" paid voluntarily. The statutory text is narrow.
-
Exempt employees who get "overtime" don't get the deduction. FLSA § 13 exempts executive, administrative, professional, outside-sales, and certain computer employees from overtime requirements. An employer who voluntarily pays such an employee "overtime" for extra hours has paid wages, but those wages aren't FLSA-required. Box 12 code TT reporting must exclude these amounts. Including them is the most-likely-to-be-discovered reporting error since the W-2's other boxes will flag the exempt status.
-
Withholding doesn't change. The IRS did not update Circular E withholding tables for OBBB. Employees see the benefit at tax filing, not on each paycheck. With roughly 17 million filers expected to benefit from the deduction (Tax Policy Center estimate), the volume of "where's my bigger paycheck?" employee questions in Q1 2026 will be non-trivial. Workers expecting bigger checks starting "next pay period" will be told their employer is shorting them — even though nothing changed and the benefit lands at tax time. The single most-likely employee-relations friction point from this provision.

What OBBB actually says
The relevant statutory text is at 26 U.S.C. § 225, added by Section 70202(a) of P.L. 119-21. The definition that does the work — and that the rest of the regulation flows from — is in subsection (c):
"The term 'qualified overtime compensation' means overtime compensation paid to an individual required under section 7 of the Fair Labor Standards Act of 1938 that is in excess of the regular rate (as used in such section) at which such individual is employed." — 26 U.S.C. § 225(c)
Three subsections set the rest of the rules:
- § 225(a) grants the deduction: "There shall be allowed as a deduction for the taxable year an amount equal to the qualified overtime compensation received by the taxpayer during the taxable year."
- § 225(b) sets the cap and phase-out: $12,500 / $25,000 limit; $100 reduction per $1,000 of MAGI above $150,000 / $300,000.
- § 225(g) sunsets the deduction for tax years beginning after December 31, 2028.
Two phrases in § 225(c) set the limits behind the headline. "Required under section 7 of the FLSA" excludes everything that is not federally required overtime. "In excess of the regular rate" restricts the deduction to the premium portion only, not the full overtime payment.
Who qualifies, and how much
The deduction is below-the-line on the new Schedule 1-A to Form 1040 — it reduces taxable income, not AGI. Mechanically, Schedule 1-A line 38 flows to Form 1040 line 13b, which is then subtracted from AGI (line 11b) along with the standard or itemized deduction (line 12e) to arrive at taxable income (line 15). Schedule 1-A is available whether the taxpayer takes the standard deduction or itemizes. Because § 225 does not reduce AGI, many states do not pick it up automatically. Two procedural gates also matter: the return needs a valid Social Security number, and married taxpayers must file jointly. The deduction is per return, not per worker — a household with two FLSA-overtime earners filing jointly shares the $25,000 cap, not $25,000 each.
Phase-out math worth running once: a single filer at $180,000 MAGI has $30,000 excess over the $150,000 threshold, which reduces the maximum $12,500 deduction by $3,000 to $9,500. A single filer at $275,000 MAGI is fully phased out. Joint phase-out is twice as forgiving: full deduction available through $300,000 MAGI, fully phased out at $550,000.
What counts toward Box 12 code TT (and what doesn't)
The single highest-leverage operational decision is which pay codes feed Box 12 code TT. Use this as a pre-flight checklist before tax-year 2026 closes:
| Counts toward Box 12 code TT | Does NOT count |
|---|---|
| FLSA-required 0.5× premium on hours over 40 in a workweek | The 1.0× straight-time portion of the overtime check |
| FLSA premium for FLSA-nonexempt employees | Any "overtime" paid to FLSA-exempt employees (§ 13 exemptions) |
| Standard hourly, salaried-nonexempt, and piece-rate workers' FLSA OT | State daily-overtime (CA 8h, AK 8h, CO 12h, WA agricultural, etc.) |
| Properly-classified W-2 employees only | 1099 contractors' pay (except misclassification edge cases) |
| FLSA premium even when employee works in a state that decouples | Daily double-time, 7th-consecutive-day premium, holiday premium |
| FLSA premium calculated using the proper regular rate (incl. bonuses) | CBA / union-contract premiums above the FLSA floor |
| FLSA premium paid in arrears for FLSA OT worked in the same tax year | "Comp time" / time-off-in-lieu (no cash overtime paid) |
The single line that captures all of this: Box 12 code TT is the FLSA 0.5× premium, nothing more, nothing less.
Worked example: Box 12 code TT for one employee
Maria, an FLSA-nonexempt warehouse associate in Texas, earns $25/hr regular rate. Over tax year 2026 she works:
- 40 weeks at 40 hours flat (no overtime — 1,600 hours straight time)
- 10 weeks at 48 hours (40 hours straight + 8 hours FLSA overtime each week)
- 2 weeks at 50 hours (40 hours straight + 10 hours FLSA overtime each week)
Total FLSA-overtime hours for the year: (8 × 10) + (10 × 2) = 100 hours. Maria's overtime pay per hour is $37.50 (1.5 × $25), of which the 0.5× premium is $12.50. Box 12 code TT amount on Maria's 2026 W-2 = 100 × $12.50 = $1,250.00.
Maria's total overtime pay (the full 1.5×) for the year was $3,750. Notice the W-2 Box 12 TT figure ($1,250) is exactly one-third of her total overtime pay — that's the 0.5× / 1.5× ratio. If a payroll system reports Maria's full $3,750 in Box 12 TT instead of $1,250, it has overstated qualified overtime by $2,500. Maria's federal return would then claim a deduction $2,500 larger than she's entitled to — and the employer has filed an incorrect W-2 subject to § 6721 penalties.
Now consider Maria with the same hours but located in California instead of Texas. Her FLSA-required overtime is still 100 hours (same federal weekly-40 rule). But suppose 30 of those federal-OT hours overlapped with California's daily 8h overtime — those 30 hours already triggered state-OT premium even before they triggered the FLSA premium. Maria's Box 12 code TT amount on her W-2 is still $1,250 (the FLSA premium portion is identical regardless of state). The fact that her California daily-OT premium also applies for state-tax purposes is on her state return, not her W-2 federal box.
How this stacks with "No Tax on Tips"
OBBB Section 70201 created a parallel deduction for qualified tip income (new IRC § 224), capped at $25,000 with the same MAGI phase-out, also below-the-line on Schedule 1-A, also sunsetting December 31, 2028. Tipped employees in occupations on the IRS qualified-tip-occupation list can claim both deductions on the same return — § 225 against FLSA premium overtime and § 224 against tips — subject to each one's separate cap. Each deduction has its own W-2 box (Box 12 code TT for overtime; Box 12 code TP for tips that qualify, plus code TS for tips from specified service trades or businesses that don't qualify), so payroll systems must isolate both. The two phase out at the same MAGI thresholds, so a high earner phasing out of one is phasing out of the other. Worth a sentence in employee FAQs at restaurant, hospitality, and salon employers; otherwise tipped workers may not realize both apply. For the § 224 federal mechanic in detail — qualified-tip definition, the 70+ Treasury Tipped Occupation Codes, Box 12 code TP + Box 14b TTOC reporting, and where state conformity diverges from § 225 (Colorado conforms to § 224 even though it decoupled from § 225 via HB 25-1296) — see our no-tax-on-tips guide.
W-2 / 1099 reporting requirements
Tax-year 2025 W-2s (issued January 2026) carry no mandatory new fields. The IRS Notice 2025-69 explicitly preserves the existing W-2, 1099-NEC, 1099-MISC, and 1099-K forms unchanged for 2025. Employees calculate their own deduction from pay records and the IRS FS-2026-01 Q&A Schedule 1-A instructions. Employers may voluntarily report 2025 qualified overtime in Box 14 with a suggested label "FLSA OT Prem"; failure to do so is covered by penalty relief under Notice 2025-62.
Tax-year 2026 is where the load shifts to employers. The IRS finalized the 2026 Form W-2 on January 12, 2026 with a new Box 12 code TT: "Total amount of qualified overtime compensation." The amount reported is the FLSA premium portion only — the 0.5× in time-and-a-half, not the full 1.5× overtime check. Statutory basis for the reporting requirement is IRC § 6051(a)(19); the parallel 1099 requirement under § 6041(d)(4) updates Forms 1099-NEC and 1099-MISC for the limited misclassification edge case.
Reporting accuracy matters because the penalty for incorrect information returns under § 6721 is $310 per form (2026 figures), capped at $3.78M per year per employer. An employer with 200 hourly workers who folds California daily overtime into Box 12 code TT for all 200 W-2s has overstated qualified overtime on 200 returns; each return is a separate penalty exposure.
State conformity
State income-tax treatment of the federal deduction depends on two things: (1) where the state's income-tax base starts on the federal return — federal AGI (Line 11b) or federal taxable income (Line 15) — and (2) whether the state legislature has decoupled. Because § 225 is below-the-line (it reduces federal taxable income but does NOT reduce federal AGI), a state that starts from federal AGI does NOT pick up the deduction automatically; a state that starts from federal taxable income does — unless the state legislature has explicitly added it back.
State-level treatment of the federal § 225 overtime deduction (May 2026). Decouplers require federal add-back on the state return; no-income-tax states are moot at the state level; uncolored states default to general conformity or pending guidance.
For most states, the federal deduction does not lower state taxable income. The reason is usually structural: § 225 reduces federal taxable income, not AGI, and most states start from AGI. Some states also issued explicit non-conformity guidance or add-back rules:
- California — SB 711 conformity-date cutoff. California Senate Bill 711, signed by Governor Newsom on October 1, 2025 (Chapter 231 of 2025 Statutes), amended Revenue and Taxation Code § 17024.5(a)(1) to set California's IRC conformity date to January 1, 2025. OBBB was enacted July 4, 2025 — six months after the cutoff — so § 225 is structurally outside California's tax base. There is no FTB add-back form line; the deduction is simply not recognized. The California Franchise Tax Board's November 2025 Tax News confirms: "California does not conform to the deduction for the overtime paid." Projected revenue protection: ~$3.2 billion annually. California workers — who already have the deepest non-qualifying overtime exposure (daily 8h, daily double-time, 7th-day premium) — get the worst combined posture: little federal benefit on most of their overtime, and no state benefit on the rest.
- New York — IT-225 add-back codes. The 2026 IT-225 (state add-back / subtraction schedule) has new codes for "Add-back of exempt overtime pay" and "Add-back of exempt tip income." Governor Hochul has separately proposed a state-level exemption for tipped income (SB S587-A, introduced January 2026) — that proposal targets tips only and does not extend to overtime; the IT-225 add-back of federal exempt overtime remains in place.
- Illinois — non-conformity (Illinois Department of Revenue / Illinois OMB). Illinois OMB cited approximately $267 million in state revenue protection as the policy rationale. For 2026, Illinois employers must implement dual-track reporting: separate calculations for federal taxable income (with the OBBB deduction applied) and Illinois state taxable income (with the OBBB amount added back).
- Colorado — HB 25-1296 add-back, effective Jan 1, 2026. Colorado House Bill 25-1296 requires individuals to add back any overtime compensation deducted on IRS Schedule 1-A when calculating Colorado taxable income. The Colorado DR 0104 return adds a line for "Excess federal deduction for overtime pay."
Four states currently pass the deduction through to state taxable income: Oregon, Idaho, North Dakota, and South Carolina. Oregon affirmatively retained the passthrough; Idaho, North Dakota, and South Carolina currently pass it through because they start from federal taxable income and have not added § 225 back.
Static-conformity and AGI-starting states often get to the same answer for different reasons. A state can block the deduction because its conformity date sits before OBBB, because it adds the deduction back, or because the federal deduction never touches the AGI number the state imports. The employee result is usually the same: federal benefit, no state benefit.
No-income-tax states are moot. Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming don't tax wage income, so the state-conformity question doesn't apply. (New Hampshire's interest-and-dividends tax was phased out as of January 1, 2025; wages were never taxed.) Workers in these states get the federal deduction without any state-side wrinkle.
Other rolling-conformity states. A state that starts from federal taxable income (Form 1040 Line 15) and has not decoupled will pass the deduction through automatically. A state that starts from federal AGI (Line 11b) does NOT pass it through, because § 225 is below AGI. Each employer should verify the specific posture for every state they pay employees in — the article's confirmed-decoupler list is the floor, not the ceiling, and state DOR guidance is still being issued through 2026.
State-specific guidance through state Departments of Revenue is still rolling out as of Q2 2026; the practical message for HR managers is "check your state's current instructions before finalizing payroll posture." For the full 50-state + DC grid — including the AGI vs federal-taxable-income starting-point mechanic and the operational steps for multi-state payroll teams — see our no tax on overtime by state guide.
Multi-state and remote workers
The federal deduction is identical regardless of where the employee physically works — it's federal income tax, sourced to the employee's federal return. State income-tax treatment, on the other hand, is sourced to the state where the employee works (with narrow exceptions for some reciprocal arrangements). For the deeper treatment of how state overtime rules vary, see our overtime rules by state guide; for cases where off-the-clock pay retroactively cascades into FLSA-required overtime (and therefore into the § 225 deduction), see our off-the-clock work by state guide.
Practical implication for a Texas-headquartered company with a California remote employee: the employee gets the federal deduction on their 1040 (TX has no state income tax for the worker, CA does). On the CA state return, the same FLSA-premium overtime will be added back per CA's decoupling. The employee's combined effective tax savings is smaller than the headline number, even though the federal deduction itself works normally.
For payroll-team posture: state withholding stays governed by work location (subject to the usual mobility and reciprocity rules), and 2026 W-2 Box 12 code TT reporting is identical regardless of work-state. The state-return treatment is separate from the federal W-2 reporting task, so employers should explain the distinction without trying to give personal tax advice.
Recent changes
Six events have shaped the OBBB overtime-deduction rollout from signing to sunset. The first two W-2 reporting events matter most for employers: tax-year 2025 voluntary reporting and tax-year 2026 mandatory reporting. State revenue-agency guidance is still rolling out as of Q2 2026.
- July 4, 2025 — OBBB signed into law (Public Law 119-21). Section 70202(a) of P.L. 119-21 adds the qualified-overtime-compensation deduction to the Internal Revenue Code as new 26 U.S.C. § 225. Effective retroactively to tax years beginning January 1, 2025.
- November 21, 2025 — IRS Notice 2025-69 — 2025 transition relief. IRS confirmed that 2025 Forms W-2, 1099-NEC, 1099-MISC, and 1099-K are unchanged for the 2025 tax year. Employees calculate the deduction themselves from pay records. Employers may voluntarily disclose qualified overtime in Box 14 of the 2025 W-2 (suggested label "FLSA OT Prem"). Penalty relief for non-disclosure issued in Notice 2025-62.
- January 12, 2026 — IRS releases finalized 2026 Form W-2 with Box 12 code TT. New Box 12 code TT — "Total amount of qualified overtime compensation" — becomes mandatory for tax year 2026 (W-2s issued January 2027). Amount reported is the FLSA premium portion only (the 0.5×), not the full 1.5× overtime pay. Forms 1099-NEC and 1099-MISC are similarly updated for the misclassification edge case.
- January 2026 — IRS Fact Sheet FS-2026-01 — taxpayer Q&A. IRS published a question-and-answer fact sheet addressing the most common taxpayer questions: cap math, MAGI phase-out, single vs joint filing requirements, Schedule 1-A line item. Several mechanical questions remain pending (retroactive back-pay, bonus recharacterization, weighted-average regular-rate interactions with shift differentials).
- Q1–Q2 2026 — state DORs publish conformity guidance. State treatment is not uniform. Oregon, Idaho, North Dakota, and South Carolina currently let the federal deduction lower state taxable income. California, New York, Illinois, Colorado, Maine, Hawaii, Connecticut, and DC have explicit non-conformity statements or contested guidance, and many other states never pick up the deduction because they start from AGI. State-specific guidance is still rolling out as of May 2026.
- December 31, 2028 — sunset — deduction terminates. IRC § 225(g) sunsets the deduction for tax years beginning after December 31, 2028. Four tax years available: 2025, 2026, 2027, 2028. Absent a Congressional extension, qualified overtime compensation becomes ordinary taxable income again starting tax year 2029.
Frequently Asked Questions
Is overtime really tax-free now?
No. Per 26 U.S.C. § 225(a)-(c), the OBBB created a federal income-tax deduction for the FLSA-premium portion of overtime, capped at $12,500 per individual ($25,000 joint), phased out above $150,000 MAGI ($300,000 joint), and sunsetting December 31, 2028. Social Security, Medicare, and most state income taxes still apply to the full overtime check. Withholding tables were not changed; employees see the benefit at tax filing, not on each paycheck.
Does California daily overtime qualify for the deduction?
No. IRC § 225(c) defines "qualified overtime compensation" as overtime "required under section 7 of the Fair Labor Standards Act" — the federal weekly 40-hour rule only. California's daily 8-hour overtime, daily double-time, the 7th-consecutive-day premium, and any CBA or employer-policy overtime above the FLSA floor do not qualify. California has the highest concentration of non-qualifying overtime in the country; the expectations gap with CA-based hourly workers is significant.
Does the deduction apply to 1099 contractors?
No, generally. FLSA § 7 applies to employees, not independent contractors, so a true 1099 worker has no "FLSA-required overtime" to deduct. The reporting infrastructure on Form 1099-NEC exists only for misclassification edge cases — where someone treated as a contractor is, under the FLSA economic-realities test, actually an employee owed federal overtime. If you're reading this as a 1099 contractor expecting tax relief on overtime, double-check your classification status.
What about overtime paid to exempt employees by employer policy?
Doesn't qualify. The statute requires overtime "required under section 7 of FLSA" — and FLSA § 13 exempts executive, administrative, professional, outside-sales, and certain computer employees from overtime requirements entirely. An employer who voluntarily pays a salaried-exempt manager "overtime" for extra hours has paid wages that don't qualify for the § 225 deduction, even if the math looks the same on the pay stub.
Will my paycheck go up because of this?
No. IRS guidance was explicit that 2025 and 2026 withholding tables are unchanged. The deduction is claimed on the annual return via Schedule 1-A — employees see the benefit at tax-filing time (refund or smaller liability), not in each paycheck. This is a frequent disappointment for hourly workers who saw "no tax on overtime" headlines and expected immediate paycheck increases. Communicate proactively if your workforce is asking.
What does my W-2 look like in 2026 vs 2027?
For tax year 2025 (W-2s issued January 2026): no mandatory separate reporting. Per IRS Notice 2025-69, employers may optionally show qualified overtime in Box 14 (suggested label "FLSA OT Prem"); penalty relief for not reporting is in IRS Notice 2025-62. For tax year 2026 (W-2s issued January 2027): mandatory separate reporting in Box 12 code TT — the IRS finalized the 2026 Form W-2 on January 12, 2026. The statutory basis is IRC § 6051(a)(19). The Box 12 amount is the FLSA premium portion only (the 0.5× extra), not the full 1.5× overtime check.
Do I have to itemize to claim this deduction?
No. The deduction is claimed on the new Schedule 1-A to Form 1040 and reduces taxable income, not AGI. It is available whether the taxpayer takes the standard deduction or itemizes. Two practical requirements: the taxpayer must have a valid Social Security number on the return, and married taxpayers must file jointly to claim it (the joint cap of $25,000 isn't available via separate-filing).
Does my state honor the federal deduction on my state return?
Depends on the state. California has decoupled — per California Franchise Tax Board guidance, the federal QOC is added back on the state return; projected revenue impact is roughly $3.2 billion annually. New York has decoupled via new IT-225 add-back codes for "Add-back of exempt overtime pay" published by the NY Department of Taxation and Finance. Most rolling-conformity states (Colorado, Illinois, New Mexico, North Dakota) automatically adopt the federal change unless the legislature acts to decouple. Static-conformity states (Virginia, Wisconsin) need affirmative legislation to conform; default is no state-level benefit. State guidance through state DORs is still rolling out through Q2 2026.
How much will the average worker actually save?
Depends on overtime hours, regular rate, and marginal tax bracket. A single FLSA-nonexempt worker earning $25/hr regular rate, putting in 5 hours of FLSA overtime per week (260 hours/year), generates $3,250 in qualifying premium (the 0.5× — $12.50/hr × 260 hours). At a 22% marginal federal bracket, the tax savings is ~$715. The frequently-cited "average worker saves $1,400" headline comes from Tax Policy Center scoring (~17 million filers projected to benefit, average tax change ~$1,400). The average is uneven across the beneficiary population: workers with substantial overtime hours and higher marginal brackets capture most of the dollar value, while workers with modest overtime hours in the 12% bracket land closer to $400–$1,000. The cap binds for unusually high overtime exposure.
Does retroactive overtime pay for 2025 count for the 2025 deduction?
Unclear as of May 2026. The IRS has not issued definitive guidance on the timing question for retroactive pay (e.g., a 2026 settlement or back-pay award covering 2025 unpaid FLSA overtime). The conservative reading is "deductible in the year received," following ordinary cash-basis principles for individual taxpayers — which would mean retroactive 2025 pay received in 2026 falls under the 2026 deduction with 2026's cap. Wait for further IRS guidance or consult tax counsel before relying on either treatment for a material amount.

Most of the reporting risk is forward-looking: tax-year 2026 W-2s (issued January 2027) are the first compliance event with mandatory Box 12 code TT. For now, the action items are setup and audit, not remediation.
-
Audit payroll system pay-code tracking. Confirm the system can isolate the FLSA-premium portion (0.5× above regular rate on FLSA-required overtime) separately from regular-rate pay, from state-only overtime (CA daily, WA daily, etc.), from double-time, from CBA premiums, and from any exempt-employee policy "overtime." Major payroll vendors (ADP, Gusto, Paychex, Rippling, isolved) released OBBBA-ready updates through late 2025; if you're on a legacy or custom payroll system, verify Box 12 code TT support before the 2026 plan year closes.
-
Reconfigure overtime categorization. The pay codes that feed into Box 12 code TT must exclude every dollar that isn't FLSA-required. The most-missed category is California daily 8h overtime treated as if it qualified. Audit each pay code against § 225(c)'s "section 7 of the FLSA" requirement.
-
Identify FLSA-exempt employees getting policy "overtime." Pull the exempt-status flag from your employee master file and cross-reference with any pay codes labeled "overtime." Any policy "overtime" paid to exempt employees must be excluded from Box 12 code TT, even if the math looks identical to a non-exempt employee's FLSA overtime.
-
Decide on 2025 voluntary disclosure. Notice 2025-69 makes 2025 reporting optional. Most employers should skip it — calculating QOC from pay stubs is straightforward for employees who care, and voluntary disclosure introduces inquiry risk if the methodology is later judged wrong. If you choose to disclose, use the IRS-suggested Box 14 label "FLSA OT Prem" and document the methodology.
-
Update employee communications proactively. Year-end materials, pay-stub explainers, and FAQ pages should flag the four most common misconceptions: (1) no withholding change, (2) only the 0.5× premium, (3) state overtime doesn't qualify, (4) sunset in 2028. The communications cost of a confused workforce dwarfs the reporting cost of getting Box 12 right.
-
Set a state-decoupling watch. California and New York are confirmed decouplers. State DOR guidance is still rolling out through 2026 in many other states. Subscribe to or monitor the state DOR bulletins for every state you have employees in; a state decoupling mid-year materially changes payroll-team communications even though it doesn't change W-2 reporting.
-
If a 2025 misreporting error is discovered post-filing, the relief mechanism is a corrected W-2 (Form W-2c) — but Notice 2025-69 explicitly bypasses mandatory 2025 reporting, so most "errors" don't exist as such. The exposure rises materially with the 2026 W-2.
The through-line
The practical rule is narrow: the deduction is capped, phased out, temporary, and limited to the FLSA-premium portion of overtime. Make sure your payroll system isolates exactly that slice — the 0.5× premium on hours over 40 per workweek for FLSA-nonexempt employees — from everything else. If the W-2 reports the wrong slice, each affected W-2 can become a separate information-return problem. The compliance window opens in earnest with 2026 W-2s issued January 2027 and closes for tax-year 2029 absent Congressional extension.
The good news: the pay-code separation work is the same compliance you'd do for accurate FLSA regular-rate calculations regardless of OBBB. If Congress extends or makes the deduction permanent in 2028, the audit work doesn't need to be redone. If it expires, you have cleaner payroll data anyway. Build it now and it earns its keep either way.
