Gusto + Section 125 — Built-In Native Support

By David Newman · Referral Partner, Section 125 Savings · San Pedro, CA

Gusto offers native Section 125 cafeteria plan support across all of its tiers (Simple, Plus, Premium, and Concierge). The platform was designed with cafeteria plan deductions as a first-class feature, which makes Section 125 implementation particularly clean for Gusto users.

From your perspective, the Gusto-side configuration is straightforward: the plan administrator coordinates with you (or your Gusto admin user) to add the Section 125 Preventive Care deduction. The platform handles tax treatment, W-2 reporting, and reporting to the plan administrator automatically.

Setup steps

  1. ACA Solutions plan administrator provides enrollment data + the Section 125 deduction structure.
  2. Inside Gusto: Settings → Deductions → Add Deduction → Type: Pre-tax (Section 125 Cafeteria Plan). Gusto auto-configures the deduction as pre-tax for FICA, federal income tax, and (where applicable) state income tax.
  3. Employee enrollment data is imported via Gusto's CSV upload or via direct API integration with the plan administrator's system.
  4. Year-end W-2 reporting is automatic. Gusto handles Box 1, Box 3, Box 5 reductions and Box 14 disclosure without manual intervention.

Deduction code

Configurable in Gusto. Common naming: 'Sec 125 Preventive Care' or 'Section 125 Wellness Plan'.

Notes specific to Gusto

  • Gusto's reporting tools automatically classify Section 125 deductions in standard payroll reports, P&L exports, and tax filings.
  • If you use Gusto's HR features (org chart, time tracking, document storage), the Section 125 enrollment integrates with employee profiles.
  • Gusto's mobile app shows employees their pre-tax deductions clearly, including the Section 125 line — useful for employee-side transparency.

ACA Solutions handles all setup. Your Gusto 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.

Direct From the U.S. Government

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.

Common Gusto-specific questions

Under 10 minutes inside the Gusto platform. The plan administrator handles the longer compliance setup (plan document, nondiscrimination testing, etc.) in parallel during the standard 6-8 week implementation.
No additional Gusto fee for Section 125 deductions. They're part of the standard product. The $35/employee/month admin fee for the Preventive Care program is separate and goes to the plan administrator (ACA Solutions Hub), not to Gusto.
Yes — they're all deduction codes that coexist. Gusto's Benefits dashboard shows all pre-tax deductions in one view.
Auto-payroll continues to work as normal. The Section 125 deduction is included in the auto-payroll calculation cycle.
Yes — Gusto's tax filing service automatically reduces FICA-taxable wages by the Section 125 deduction amount and reflects it on quarterly filings (941) and year-end W-2s. No manual adjustment required.
