Introduction
Coverage tests are critical compliance measures for qualified retirement plans under the Internal Revenue Code (IRC). They ensure that plans do not disproportionately favor highly compensated employees (HCEs) over non-highly compensated employees (NHCEs). Performing these tests is essential for maintaining tax-qualified status, avoiding penalties, and guaranteeing equitable retirement benefits across the workforce.
Key Concepts
Highly Compensated Employees (HCEs)
- Ownership-based: Employees owning more than 5% of the company at any time during the current or prior year.
- Compensation-based: Employees earning above a specified threshold (e.g., $150,000 in 2025).
Non-Highly Compensated Employees (NHCEs)
- Employees who do not meet HCE criteria.
- Must have access to the plan and receive benefits proportionate to their contributions and employer matches.
Eligible Employees
- Those meeting plan-defined age and service requirements, typically:
- Minimum age: 21 years
- Minimum service: 1 year for defined contribution plans, up to 2 years for defined benefit plans
Types of Coverage Tests
1. Ratio Percentage Test
The ratio percentage test compares the participation rate of NHCEs to that of HCEs.
Formula:
Coverage\ Ratio = \frac{\text{NHCE Participants}}{\text{NHCE Eligible}} \div \frac{\text{HCE Participants}}{\text{HCE Eligible}}Minimum Requirement: 70%
Example:
- NHCE eligible: 100, participating: 75 → 75%
- HCE eligible: 20, participating: 18 → 90%
- Coverage ratio: 75% / 90% = 83.3% → Pass
2. Average Benefit Test
- Compares the average benefits or contributions of NHCEs to HCEs.
- Ensures that benefits are proportionally similar.
Example:
- Average NHCE contribution: $3,500
- Average HCE contribution: $6,000
- Ratio: 3,500 / 6,000 = 58.3% → May fail, corrective action required
3. General Test (Defined Benefit Plans)
- Compares the benefit accrual rates of NHCEs and HCEs.
- Ensures fairness in retirement benefits allocation based on service and salary.
Safe Harbor Provisions
Employers can adopt safe harbor rules to automatically satisfy coverage requirements:
- Non-Elective Contributions: Employer contributes a fixed percentage (e.g., 3%) of compensation to all eligible employees.
- Matching Contributions: Employer matches employee contributions according to a pre-defined formula.
- Immediate Vesting: Contributions are fully vested upon allocation, preventing discrimination.
Exclusions from Coverage
Certain employees may be legitimately excluded from coverage testing:
- Employees under 21 years of age
- Employees with less than one year of service (or two for defined benefit plans)
- Union employees covered under collective bargaining agreements
- Nonresident aliens with no U.S. earned income
Corrective Actions
When a plan fails a coverage test, corrective measures include:
- Qualified Non-Elective Contributions (QNECs): Additional contributions allocated to NHCEs.
- Qualified Matching Contributions (QMACs): Extra matching contributions for NHCEs.
- Refunds to HCEs: Return excess contributions to HCEs to restore balance.
Example:
- NHCE contribution average: $3,000
- HCE contribution average: $6,000
- Plan fails test
- Corrective QNEC: $1,500 per NHCE to restore compliance
Compliance and Reporting
- Annual testing is required for all defined contribution and defined benefit plans.
- Documentation must be maintained in case of IRS audits.
- Reports often include:
- Employee participation counts
- Average benefit calculations
- Corrective actions taken
Conclusion
Coverage tests are essential to ensure fairness in qualified retirement plans, preventing benefits from favoring highly compensated employees over the broader workforce. Employers must perform regular ratio percentage, average benefit, and general tests, and implement corrective actions when necessary. Adopting safe harbor provisions simplifies compliance while maintaining equitable access and benefits for all employees, preserving the plan’s tax-qualified status and fostering workforce satisfaction.
