ADP + Section 125 — One Pre-Tax Deduction Code, No Other Changes
By David Newman · Referral Partner, Section 125 Savings · San Pedro, CA
ADP supports Section 125 cafeteria plan deductions natively across all three of its primary employer products: ADP RUN (small business), ADP Workforce Now (mid-market), and ADP Comprehensive Services (enterprise + PEO). The plan administrator handles the deduction-code setup during the standard 6-8 week implementation period.
From your operational perspective, the ADP-side change is minimal: one new pre-tax deduction code per enrolled employee, configured to reduce FICA-taxable wages by $1,200/month. Your existing ADP user permissions, payroll cycles, reporting structure, and integrations remain unchanged.
Setup steps
- ACA Solutions plan administrator coordinates with your ADP account representative (or your in-house payroll team) to add the Section 125 Preventive Care deduction code.
- The deduction is configured as pre-tax for federal income tax, Social Security, Medicare, and (in most states) state income tax. WC reportable payroll is also reduced.
- Employee enrollment data flows from the plan administrator's enrollment system to your ADP payroll via standard data export (CSV or direct API for Workforce Now and Comprehensive Services).
- First payroll cycle after go-live reflects the deduction. ADP automatically reduces Box 1, Box 3, and Box 5 wages on year-end W-2s. The annual total appears in Box 14.
Deduction code
Typically labeled '125 PREV' or 'CAF 125 PVT' or 'SEC 125 WC'. Specific naming follows your existing ADP deduction code conventions.
Notes specific to ADP
- ADP RUN's deduction-code library includes generic 'Section 125 / Cafeteria Plan' templates that work for the Preventive Care variant.
- ADP Workforce Now supports auto-mapping to W-2 Box 14 — the plan administrator confirms the mapping during implementation.
- If your ADP setup uses GL mapping, the new deduction code maps to the same GL accounts your existing pre-tax health insurance deduction uses.
ACA Solutions handles all setup. Your ADP payroll team only needs to add one pre-tax deduction code on go-live. The plan administrator handles documentation, nondiscrimination testing, and ongoing compliance. Verified compliant by CBIZ Advisors LLC and HitesmanLaw P.A. in 2025.

35+ years as an Employee Benefits attorney specializing in IRC Section 125, ERISA, HIPAA, and the ACA. Her May 5, 2025 opinion letter concludes: “In this firm's opinion, the Program described satisfies applicable IRS requirements.”
She specifically reviewed the IRS Chief Counsel Advice memoranda on "double-dip" arrangements — the exact schemes the IRS has flagged — and concluded this program is built differently and compliantly.

CBIZ independently reviewed the program against IRC §§ 125, 105, and 106, plus ERISA, ACA, and COBRA requirements. Their August 22, 2025 letter concludes: “If operated per its provisions, the Program appears to satisfy the requirements of ERISA, the ACA, and COBRA as well.”
This review was commissioned by Affinity Hospice's CEO before enrolling his nationwide organization — and the CFO (himself a CPA) shared the letter publicly in his testimonial.

Section 125 has been in the Internal Revenue Code since 1978. Congress wrote it there specifically to encourage employers to fund preventive healthcare for American workers. This is not a loophole — it is the precise, intended use of a 47-year-old federal law, grounded in IRS Revenue Ruling 69-154, the specific published ruling supporting the benefit payment structure.
