In the world of employee benefits, Section 125 pre-tax plans, Health Reimbursement Arrangements (HRAs), and Flexible Spending Accounts (FSAs) are the unsung heroes. They provide powerful tax advantages for both employers and employees, making healthcare and dependent care expenses significantly more affordable. But these plans don’t run on autopilot. They come with a non-negotiable requirement: proper ERISA documents. Failing to maintain compliant, up-to-date plan documentation for these plans isn’t just a minor oversight, it can lead to penalties, audits, and a complete loss of tax savings.

What are ERISA Documents?

According to the US Department of Labor, ERISA documents are legally required documents for employee benefit plans, including retirement and health plans, governed by the Employee Retirement Income Security Act of 1974 (ERISA).

Which Plans Need ERISA Documents?

These plans offer real financial value, but that value hinges entirely on having the proper legal documents in place. Without them, the IRS or Department of Labor could classify your plan as non-compliant.

  • Section 125 (Cafeteria) Plans allow employees to pay for certain qualified benefits—like insurance premiums or FSAs—on a pre-tax basis. This reduces federal income tax, FICA, and Medicare tax liabilities for both the employee and employer.
  • Flexible Spending Accounts enable employees to set aside pre-tax dollars for medical (Health FSA) or dependent care (Dependent Care FSA) expenses. They come with use-it-or-lose-it rules, but many plans offer grace periods or carryover features.
  • Health Reimbursement Arrangements are funded solely by the employer to reimburse employees for eligible medical expenses or premiums. Depending on the plan type—such as a traditional HRA, an Individual Coverage HRA (ICHRA), or a Qualified Small Employer HRA (QSEHRA)—the rules around participation, rollover, and integration with insurance can vary. Some are subject to ERISA (like traditional HRAs and ICHRAs), while others have special carveouts but still require proper documentation.

The Core ERISA Documents You Need to Stay Compliant

Think of your plan documents as your legal blueprint. They spell out eligibility, benefits, claims procedures, and everything in between. Here’s what you absolutely need:

Section 125 Plan Document

  • Required by the IRS for all cafeteria plans offering pre-tax benefits.
  • Must describe eligibility, benefits, election procedures, and IRS rules on irrevocable elections.
  • Applies to FSAs, dependent care accounts, Premium Only Plans (POPs), and other pre-tax benefits.

ERISA Plan Document (for plans subject to ERISA)

  • A formal legal document required under ERISA for group health plans, HRAs, and health FSAs.
  • Must outline plan operation, funding, eligibility, and claims processes.
  • Even small employers offering ERISA-covered plans must have this in place.

Note: Dependent Care Assistance Plans (DCAPs) are generally not subject to ERISA, so they don’t need an ERISA plan document—but they do need to comply with IRS Section 129 and 125.

Summary Plan Description (SPD)

  • Required under ERISA.
  • A participant-friendly summary of the ERISA plan document.
  • Must be distributed within 120 days of plan adoption.
  • Fines of up to $110/day apply if not provided upon request.

 Form 5500 (If Applicable)

  • Required annually for ERISA plans with 100+ participants (with exceptions).
  • Reports plan financials and compliance status.

 Summary of Benefits and Coverage (SBC)

  • Required for health plans under the ACA.
  • Helps participants compare benefit options.

No Proper Documentation? Here’s What Can Happen

Outdated or missing plan documents can be disastrous. Here’s what’s on the line:

  • IRS Penalties: Missing or non-compliant Section 125 documentation can result in the IRS reclassifying all pre-tax deductions as taxable income—for all employees. Employers then owe back payroll taxes, plus interest and penalties.
  • ERISA Penalties: Failure to provide an SPD can cost $110 per day, and willful violations can result in fines of up to $5,000 or even imprisonment. False statements? That’s up to $10,000 and five years.
  • ACA Penalties: Non-compliance with ACA integration rules (especially for HRAs) can trigger a $100/day per person excise tax.
  • Audit Red Flags: Both the IRS and DOL conduct audits. Missing or incorrect plan documents are top audit triggers.
  • Loss of Tax-Advantaged Status: If your plan doesn’t meet the IRS’s structural and operational requirements, the tax benefits disappear.
