What the OBBBA Proposes
The One Big Beautiful Bill Act (OBBBA) includes a provision that would eliminate federal income tax on overtime pay for hourly workers. If enacted, employees earning overtime would exclude those overtime wages from gross income for federal tax purposes — meaning no federal income tax withheld or owed on hours worked beyond 40 in a workweek.
FICA taxes (Social Security and Medicare) would still apply to overtime pay under the current proposal. Only federal income tax withholding would be affected. State income tax treatment would vary by state law.
How Overtime Tax Withholding Currently Works
Today, overtime pay is taxed as ordinary income, exactly like regular wages. When an employee works 48 hours at $20/hr, all 48 hours of wages are aggregated for withholding purposes. The overtime premium (the extra $10/hr for the 8 OT hours) doesn't get any special tax treatment — it's all just wages.
This means a worker in the 22% bracket who earns $160 in overtime pay loses about $35 to federal income tax on those OT earnings, on top of FICA.
What Would Change for Payroll Under OBBBA
If the provision passes as currently written, payroll systems would need to:
- Identify overtime pay as a separate compensation component
- Exclude overtime wages from federal taxable wages on the employee's paycheck
- Continue withholding FICA on overtime wages
- Report overtime wages separately on W-2 forms (likely in Box 12 with a new code)
The implementation burden falls on payroll systems and HR software vendors. Most major platforms — ADP, Paychex, Workday, UKG — would need configuration updates. For payroll managers, this means watching for system updates and testing before the effective date.
FLSA Regular Rate Interaction
One open question: how does tax-exempt overtime interact with the FLSA regular rate calculation? Under current FLSA rules, the regular rate includes all remuneration for employment. If overtime wages are excluded from income tax but still constitute "wages" under FLSA, the regular rate calculation doesn't change. Overtime would still be calculated at 1.5x the regular rate — it would just be taxed differently.
This distinction matters because some proposed implementations could create confusion about whether FLSA overtime calculations are affected. They shouldn't be — FLSA is a labor law, OBBBA is a tax law. They operate independently.
Legislative Status
As of early 2026, the OBBBA has passed the House and is under consideration in the Senate. The overtime tax exclusion has bipartisan appeal but also significant revenue concerns — the Joint Committee on Taxation estimated it would reduce federal revenue by hundreds of billions over ten years. The final bill may look different from what passed the House.
Payroll managers should monitor the bill's progress but not implement changes until legislation is enacted and IRS guidance is issued. Acting early based on a proposal that changes or fails could create compliance problems.
What to Do Right Now
Don't change anything yet. The right moves are to bookmark IRS guidance pages, subscribe to your payroll software vendor's update notifications, and run a sample calculation to understand the impact on your workforce using the Overtime Tax Calculator. Knowing your numbers ahead of time makes implementation smoother when (if) the law passes.
