One Big Beautiful Bill Act’s Impact on Payroll Processing

July 11, 2025

While more guidance from the IRS will be forthcoming, there are two key provisions in the One Big Beautiful Bill Act (OBBB) that directly impact payroll processing: overtime pay & tips reporting.

The new law allows employees to deduct up to $12,500 of qualified overtime pay ($25,000 for joint filers) from their federal taxable income for tax years 2025 through 2028. While this is a benefit at the employee tax return level, there are several changes that will impact payroll systems & employers.

  1. No change to overtime calculation or tax withholding responsibilities: Overtime must still be calculated under the Fair Labor Standards Act. Federal, state and local income tax withholding remains in place; however, employees may see reduced tax liability at filing. Social Security and Medicare (FICA) taxes still apply to all overtime wages.
  2. New Tracking & Reporting Requirements: Payroll systems may need updates to separately track overtime pay eligible for the deduction. Form W-2 may require new fields (e.g., Box 12 or Box 14) to identify qualified overtime. The IRS is expected to issue further guidance on tracking and reporting “qualified overtime.”
  3. Employee Impact: Eligible employees may receive larger refunds or reduced tax bills. Employees might choose to adjust their W-4 to account for the new deduction.

The law also introduces a deduction of up to $25,000 in qualified tip income per taxpayer (subject to income limits), starting in tax year 2025.

What this means from a payroll standpoint:

  1. Tip Reporting Continues: Employees must continue to report all cash and electronic tips. Tips remain part of total taxable wages and must be processed as usual.
  2. Federal Tax Deduction – Employee Level Only: The deduction applies when employees file their personal federal tax returns. It does not change withholding requirements during the year. Employees may opt to adjust their W-4 for lower withholding based on the anticipated deduction.
  3. No Changes to FICA Rules: Tips remain subject to Social Security and Medicare taxes. Uncollected FICA (due to insufficient regular wages) will still be reported on the W-2.
  4. W-2 Reporting Enhancements: Tip income may need to be separately reported under new IRS instructions to support deduction claims.
  5. Other Considerations: The deduction applies to federal taxes only—state and local taxes still apply. Only “qualified tips” (voluntary, customer-determined) count toward the deduction. The Treasury is expected to clarify eligible occupations and definitions.

In summary:

  • Payroll services must continue to calculate and withhold overtime and tip income per FLSA and current tax laws.
  • Federal deductions for overtime and tips do not impact withholding processes but will impact year-end reporting and system requirements.
  • Stay tuned for further IRS and Treasury guidance.
