A Section 125 plan is a powerful tax-saving tool—but it only works if it’s structured and maintained in full compliance with federal laws. IRS Section 125 rules are designed to protect both employers and employees, covering everything from plan documentation to day-to-day administration.
Below is an overview of the key compliance areas every business should understand before implementing or updating a Section 125 plan.
The foundation of every IRS Section 125 plan is found in IRS Code Section 125, which defines how employees may use pre-tax dollars to pay for qualified benefits. Under these rules, the IRS requires:
A written Plan Document detailing exactly how the plan works
A Summary Plan Description (SPD) for employees
Clear rules on eligibility, contributions, and qualifying benefits
Annual nondiscrimination testing to ensure the plan doesn’t unfairly favor highly compensated employees
Failing to comply with IRS Code Section 125 requirements can cause the plan to lose its tax-advantaged status—resulting in tax liabilities for both employers and employees.
If your plan includes medical coverage, it must meet the ACA’s Minimum Essential Coverage (MEC) requirements. This ensures that employees have access to affordable and adequate healthcare coverage. Employers subject to the ACA’s employer mandate must also provide proper reporting to the IRS each year.
HIPAA safeguards the privacy and security of employee health information. If your Section 125 plan handles any protected health information (PHI)—for example, through health reimbursement arrangements or wellness programs—your provider must follow HIPAA’s strict privacy and security rules.
Most IRS Code Section 125 cafeteria plans are treated as welfare benefit plans under ERISA. As a result, employers may be required to:
Provide employees with clear plan information
File annual Form 5500 (if required)
Follow fiduciary responsibilities to act in employees’ best interests
Compliance under an IRS Section 125 plan is not a one-time task. Ongoing maintenance typically includes:
Annual nondiscrimination testing to verify fairness
Document updates if benefits or eligibility change
Open enrollment communications to ensure employees understand their options
Proper record keeping for IRS and DOL audits
