Section 125 Form 5500 Requirements — When You Need to File

Section 125 cafeteria plans don't require Form 5500 directly, but certain ERISA welfare plan components (group health insurance, etc.) operating through a cafeteria plan may trigger Form 5500 filing for plans with 100+ participants.

Here's the deeper detail — including the underlying authority, the practical implications, and what it means for your specific situation.

Most Section 125 questions follow a similar pattern: there's a federal statutory answer (often well-settled and decades old), a practical operational answer (handled by your plan administrator), and an employer-specific answer (returned by the free 15-minute analysis call with the tax specialist). The Preventive Care variant we work with is structured to give clean answers across all three.

How the math works (in 90 seconds)

For every enrolled W-2 employee earning $25,000+/year and covered under an ACA-compliant group health plan:

• Pre-tax salary reduction: $1,200/month · $14,400/year
• Employer FICA savings (7.65%): $1,101.60/year
• Net employer savings: $681.60/employee/year
• Employee net take-home raise: +$71.96/paycheck (~$863/year)
• Workers' Comp reduction: 30–60% real-world at next audit cycle (because WC base = taxable payroll, which Section 125 reduces by definition)

A 50-employee company nets $34,080/year in net FICA + industry-specific WC reduction. Run the calculator → for your specific number.

Form 5500 filing specifics for Section 125 plans

Form 5500 is the annual return filed jointly with the Department of Labor and the IRS for ERISA-covered welfare benefit plans. For Section 125 cafeteria plans, the Form 5500 filing requirement depends on the plan structure and participant count:

Plans subject to Form 5500 filing:

• ERISA welfare benefit plans (most § 125 plans that include group health, dental, vision, or FSA components fall in this category) with 100+ participants on the first day of the plan year file Form 5500 with applicable schedules.
• Plans with fewer than 100 participants generally qualify for a "small plan" exemption that allows filing of Form 5500-SF (Short Form) instead, with reduced disclosure requirements.

Filing details:

• Due date: Last day of the 7th month after the plan year end (July 31 for calendar-year plans). One automatic 2.5-month extension available via Form 5558.
• Schedules: Schedule A (insurance contracts), Schedule C (service providers), Schedule H (financial information for plans with 100+ participants), Schedule I (financial information for small plans).
• Filing method: Electronic via the EFAST2 system. The plan administrator typically files on behalf of the operator under a power-of-attorney authorization.

Penalties for non-filing or late filing can be substantial — DOL imposes penalties up to $2,259/day (indexed) for late or missing filings under ERISA § 502(c)(2). The plan administrator handles the filing under the standard administrative agreement, which removes the most common compliance failure point for ERISA-covered plans.

For § 125 plans with only premium-only-plan (POP) features and no other ERISA-covered components, no Form 5500 filing is required — the POP-only structure is exempt from ERISA Title I reporting under DOL regulations.
