IRC Section 125 Cafeteria Plan Nondiscrimination Testing & Safe Harbor Auditor

Statutory Guide to IRC Section 125 Cafeteria Plan Nondiscrimination Testing (NDT)

Under Internal Revenue Code (IRC) Section 125, employers can establish pre-tax employee benefit arrangements, commonly called cafeteria plans. These include premium payment plans, health Flexible Spending Accounts (FSAs), Dependent Care Assistance Programs (DCAPs), and Health Savings Accounts (HSAs). To preserve the tax-advantaged status for both the employer and its workers, Section 125 mandates that these plans undergo rigorous annual nondiscrimination testing (NDT).

Why Nondiscrimination Testing Matters

If a cafeteria plan discriminates in favor of highly compensated individuals (HCIs) or key employees, those preferred employees lose their pre-tax tax advantages. They must include the value of the taxable benefits they could have selected under the plan in their gross income. Fiduciaries must perform NDT at least once a year, usually as of the last day of the plan year, using testing data that covers the entire plan year.

The Three Pillars of Section 125 Testing

To comply with IRC Section 125, standard cafeteria plans must satisfy three distinct, non-overlapping tests:

• 1. The Eligibility Test: Ensures that highly compensated individuals are not favored regarding plan participation. The test evaluates the plan’s maximum service requirement (which cannot exceed three years and must be identical for all employees) and ensures the percentage of eligible non-highly compensated employees matches at least 70% of the eligibility rate of highly compensated employees (using IRS Safe Harbor percentages).
• 2. The Contributions and Benefits Test: Measures whether the plan is operating in a discriminatory manner in practice. It ensures that benefits and employer contributions are available on a non-discriminatory basis and that highly compensated participants (HCPs) do not elect a disproportionately higher share of pre-tax benefits normalized by their compensation.
• 3. The Key Employee Concentration Test (25% Test): Limits the aggregate pre-tax benefits elected by "Key Employees" (officers with high compensation, 5% owners, or 1% owners with compensation over $150,000) to no more than 25% of the total pre-tax benefits provided to all employees under the plan.

IRS Definitions: Highly Compensated vs. Key Employees

Fiduciaries must categorize plan participants using precise IRS statutory definitions:

Section 125(j) Simple Safe Harbor for Small Employers

Small business employers with an average of 100 or fewer employees in either of the two preceding years can avoid full, complex annual nondiscrimination testing by establishing a Simple Cafeteria Plan under IRC Section 125(j). To qualify for this exemption, the employer must meet strict minimum statutory contribution criteria:

• The employer must make a minimum contribution on behalf of each eligible employee who is not a highly compensated or key employee.
• The contribution must be either at least 2% of the employee's compensation for the plan year, or double the employee's elective contributions (up to 6% of compensation).
• The contribution rate or matching method must be identical and uniformly applied across all eligible employees.

Remediation and Corrective Actions

If a plan fails a nondiscrimination test, fiduciaries must implement corrections before the last day of the plan year to preserve pre-tax treatment for non-discriminatory employees. This can include:

• Capping highly compensated employee or key employee election amounts mid-year or prior to the start of the plan year.
• Increasing matching contributions or wellness credits targeted at non-highly compensated employees to boost participation.
• Broadening eligibility definitions to include part-time, temporary, or seasonal employees, improving the Non-HCI eligibility ratio.
