Section 125 Nondiscrimination Testing: How to Pass

When offering employee benefits, compliance is just as important as cost and coverage. One area that often confuses employers is Section 125 nondiscrimination testing. If your company offers a Cafeteria Plan (sometimes called a Section 125 plan), you are required by the IRS to perform annual nondiscrimination testing.

Failing this test can result in significant tax consequences, particularly for highly compensated and key employees. In this guide, we’ll break down what Section 125 nondiscrimination testing is, why it matters, and — most importantly — how to pass it.

What Is a Section 125 Cafeteria Plan?

A Section 125 Cafeteria Plan allows employees to choose between:

• Taxable benefits (such as cash compensation)

• Qualified nontaxable benefits (such as health insurance, dental, vision, FSA contributions, etc.)

The advantage is that employees can pay for certain benefits with pre-tax dollars, reducing both their taxable income and the employer’s payroll tax liability.

But here’s the catch: to ensure fairness, the IRS requires these plans to pass nondiscrimination testing.

What Is Section 125 Nondiscrimination Testing?

The goal of nondiscrimination testing is to make sure a cafeteria plan does not unfairly favor highly compensated employees (HCEs), officers, or key employees at the expense of rank-and-file employees.

The IRS does not want only executives to reap the tax advantages.

The Three Main Tests:

1. Eligibility Test – Ensures that a broad group of employees is eligible to participate in the plan.

2. Contributions & Benefits Test – Ensures that contributions or benefits are not disproportionately provided to HCEs or key employees.

3. Key Employee Concentration Test – Ensures that benefits provided to key employees do not exceed 25% of the total benefits provided to all employees.

Who Counts as a Highly Compensated or Key Employee?

• Highly Compensated Employee (HCE):

  • A 5% owner, regardless of compensation.

  • An employee earning more than $155,000 in 2024 (indexed annually).

• Key Employee:

  • A 5% owner, or

  • A 1% owner earning more than $150,000 annually, or

  • An officer earning more than $220,000 in 2024.

If your benefits disproportionately benefit these groups, your plan risks failing the test.

Why Passing Nondiscrimination Testing Matters

If your plan fails:

• HCEs and Key Employees lose tax-favored status — their pre-tax contributions become taxable income.

• The employer may face penalties for improper tax treatment.

• It could trigger IRS scrutiny of your entire benefits program.

Passing the test ensures:
✅ Compliance with IRS rules
✅ Tax savings for all employees
✅ Avoidance of costly corrections

How to Pass Section 125 Nondiscrimination Testing

Here are strategies employers can use to ensure compliance:

1. Conduct Testing Early and Annually

Don’t wait until year-end. Run a mid-year test to spot potential issues while there’s time to adjust.

2. Broaden Eligibility

Avoid limiting eligibility to certain classes of employees. The more inclusive your plan, the easier it is to pass.

3. Monitor Plan Design

Watch for plan designs that disproportionately benefit HCEs (like higher employer contributions for executives).

4. Balance Employer Contributions

Provide similar employer contribution levels across employee classes. Tiered structures should not heavily favor higher-paid groups.

5. Educate Employees

Encourage participation across the workforce. Low participation by non-HCEs is a common reason plans fail.

6. Leverage Technology & Compliance Tools

Many benefits administration platforms offer built-in nondiscrimination testing modules that simplify calculations.

7. Work With a Broker or Benefits Consultant

An experienced broker like Taylor Benefits Insurance Agency can help you design benefits that are both attractive and compliant.

What If You Fail the Test?

Failing doesn’t invalidate your cafeteria plan, but it does mean:

• HCEs’ or key employees’ benefits become taxable income.

• You may need to reclassify contributions as post-tax.

The best approach is to:

• Re-run tests early to catch issues.

• Make plan design adjustments (e.g., modify employer contributions, expand eligibility, or increase communication).

• Document corrective actions to reduce audit risks.

 Key Takeaways

• Section 125 nondiscrimination testing ensures cafeteria plans are fair and inclusive.

• There are three tests (Eligibility, Contributions & Benefits, and Key Employee Concentration).

• Failure can trigger tax consequences for HCEs and compliance issues for employers.

• Employers should run tests annually — and preferably mid-year — to avoid surprises.

• Partnering with a knowledgeable benefits broker helps you design compliant, employee-friendly plans.

Section 125 nondiscrimination testing may seem complex, but it’s crucial for maintaining compliance and ensuring your employees enjoy the full tax advantages of your benefits program.
