No Tax on Overtime: How the OBBB Overtime Exclusion Affects Small Business Payroll

The One Big Beautiful Bill (OBBB) proposes a federal income tax exclusion for overtime pay — meaning that FLSA-required overtime earnings (the extra pay for hours worked beyond 40 per week) would no longer be subject to federal income tax. For hourly workers in manufacturing, retail, food service, and other industries where overtime is common, this is a significant change. For Bay Area employers who run payroll for those workers, it creates new compliance complexity.

Here is what small business owners in Milpitas, San Jose, and Fremont need to understand before this change affects your payroll runs.

What "No Tax on Overtime" Actually Means

The OBBB overtime exclusion covers the overtime premium — the extra half-time pay that brings an employee from their regular hourly rate to time-and-a-half. The regular rate portion of overtime earnings remains taxable. Only the premium — the additional 0.5x — is eligible for the federal exclusion.

For example: a warehouse worker earning $30/hour who works 10 hours of overtime in a week earns $300 in overtime premium (10 hours × $15 premium). Under the OBBB, that $300 premium would be excluded from federal income — saving them roughly $66 in federal income tax at a 22% rate, or more depending on their bracket.

The exclusion has income-based phase-outs. Workers above certain adjusted gross income thresholds receive a reduced benefit or none at all. The exact thresholds are subject to the final bill text, so verify with a tax professional as the legislation is finalized.

Who Qualifies — and Who Doesn't

The exclusion is tied to FLSA (Fair Labor Standards Act) overtime requirements. This matters because not all overtime is FLSA overtime:

• Covered: Non-exempt hourly employees who earn overtime at 1.5× for hours over 40 per week under FLSA
• Not covered: Salaried exempt employees (executives, administrators, professionals) — their compensation is not structured as FLSA overtime
• Not covered: Voluntary overtime arrangements that pay above 1.5× by employer choice — only the statutory minimum overtime premium may qualify
• Not covered: Workers in occupations or industries that are exempt from FLSA overtime rules

For most Bay Area small businesses — restaurants with hourly kitchen and front-of-house staff, retail shops, auto repair shops, cleaning services — the overtime exclusion will apply to your non-exempt hourly workforce. For your salaried managers or professionals, nothing changes.

California Does Not Conform

As with the tip income exclusion, California will not adopt the federal overtime exclusion. California will continue to tax overtime premium income as ordinary income, subject to California's progressive rates up to 13.3%.

This creates the same split compliance challenge: zero federal income tax withholding on qualifying overtime premium, but continued California state income tax withholding on the same amount. Payroll systems must handle both simultaneously — they cannot simply apply one withholding rate to overtime earnings.

California also has its own overtime rules under state law — daily overtime (1.5× after 8 hours/day, 2× after 12 hours/day) and weekly overtime (1.5× after 40 hours/week). The OBBB's federal exclusion is based on FLSA standards, not California's more expansive overtime rules. How the exclusion interacts with California daily overtime (which has no FLSA parallel) will require IRS guidance before payroll systems can implement it cleanly.

Payroll Compliance: What Changes for Employers

Once the OBBB is enacted, employers running payroll for hourly workers will need to:

• Separate regular pay, FLSA overtime regular rate, and FLSA overtime premium in payroll records — the exclusion applies only to the premium
• Apply zero federal income tax withholding to the qualifying overtime premium (subject to income-based phase-out calculations per employee)
• Continue California state income tax withholding on all earnings including the overtime premium
• Continue FICA withholding (Social Security and Medicare) on all wages including overtime — the exclusion is income tax only
• Verify that your payroll software (QuickBooks, Gusto, ADP, Paychex) has updated its withholding logic before the first affected payroll run

What Bay Area Employers Should Do Now

1. Identify your non-exempt hourly workforce. These are the employees whose overtime will be affected. Review which roles are FLSA-covered and which are exempt — the distinction matters for the exclusion.
2. Contact your payroll provider. Ask what their timeline is for updating withholding logic and what configuration changes you'll need to make on your end. Don't assume the update is automatic.
3. Communicate with affected employees. Workers expecting smaller federal withholding need to understand why their California withholding did not change — confusion is predictable. A short explanation from you prevents unnecessary payroll inquiries.
4. Review your overtime patterns. If your business regularly runs significant overtime hours, the exclusion may meaningfully reduce your employees' federal tax burden — which could affect their annual W-4 adjustments and estimated tax calculations.
5. Wait for IRS guidance on California daily overtime. The intersection of FLSA overtime (weekly) and California overtime (daily) needs regulatory clarification before it can be implemented cleanly.
