Retirement plans are designed to help both business owners and employees save for the future in a tax-advantaged way. However, the IRS enforces rules to ensure that benefits do not unfairly favor higher-paid individuals.
These regulations classify certain participants as highly compensated employees, often referred to as HCEs. Understanding who qualifies as a highly compensated employee and how it affects plan compliance is essential for employers who sponsor retirement plans.
The highly compensated employee definition determines which workers are subject to contribution and testing limits. Employers must identify HCEs correctly each year to perform nondiscrimination testing and maintain plan compliance.
Misclassifying employees or failing to apply the correct limits can lead to plan corrections, refunds, or penalties. Knowing how HCEs are defined and managed is key to keeping a retirement plan both fair and compliant.
Understanding the Definition of a Highly Compensated Employee
A highly compensated employee is defined by the IRS using specific compensation and ownership criteria. The classification focuses on two main factors: ownership in the business and earned compensation. An employee is considered highly compensated if they meet either of these conditions during the current or prior plan year.
The first condition applies to ownership. Anyone who owns more than five percent of the company, either directly or through family attribution, is automatically classified as a highly compensated employee.
The second condition involves pay. An employee who earned more than a certain dollar threshold in the prior year, adjusted annually for inflation, is also considered an HCE. For 2025, the IRS compensation threshold is $155,000.
If an employee meets either the ownership or compensation test, they are treated as highly compensated for the current year. This classification is important because it directly impacts how the plan performs IRS nondiscrimination testing.
Why the Highly Compensated Employee Definition Matters
The highly compensated employee definition plays a critical role in maintaining the fairness of qualified retirement plans. The IRS requires that contributions and benefits not favor higher-paid employees over those who earn less. To verify this, plans must pass a series of tests each year, including the Actual Deferral Percentage (ADP) and Actual Contribution Percentage (ACP) tests.
These tests compare the average contribution rates of HCEs and non-highly compensated employees, or NHCEs. If the gap between the two groups is too large, the plan fails the test.
When that happens, the employer must take corrective action, which may include refunding excess contributions to HCEs or increasing contributions for NHCEs. Properly identifying HCEs helps prevent these costly and time-consuming adjustments.
By understanding who qualifies as highly compensated, employers can design their plans to meet both business goals and compliance requirements. Accurate classification ensures a smoother testing process and greater flexibility in funding and benefit strategies.
Ownership and Compensation Thresholds for HCEs
The IRS definition of a highly compensated employee relies on two distinct criteria. The first is the ownership test, which identifies anyone with more than five percent ownership in the business.
This ownership can include direct or indirect interests, such as shares held by a spouse, parent, child, or grandparent under family attribution rules. Even if the individual earns less than the annual compensation limit, their ownership status still classifies them as an HCE.

The second criterion is the compensation test. If an employee earned more than the IRS-set threshold in the prior year, they are considered highly compensated. For the 2025 plan year, the threshold is $155,000, based on 2024 earnings.
Employers may also choose to apply the top 20 percent election, which limits HCE status to the top-paid 20 percent of employees, reducing the number of HCEs subject to testing.
These two criteria operate independently, meaning meeting either one triggers HCE status. Employers must review ownership records and payroll data annually to identify all employees who meet the definition.
The table below summarizes the IRS criteria for classifying highly compensated employees.
| HCE Qualification | Criteria | Examples |
|---|---|---|
| Ownership Test | Owns more than 5% of the company (directly or through family) | Owner, partner, or family member with indirect ownership |
| Compensation Test | Earned more than $155,000 in the prior year (2025 threshold) | Employee with high salary or bonus income |
| Top 20% Election (optional) | Employer can limit HCE status to the top 20% of employees by pay | Used to reduce number of employees subject to testing |
Understanding these rules helps employers apply the correct classification each year and maintain IRS compliance during plan testing.
Impact on 401(k) and Profit-Sharing Plans
The classification of highly compensated employees has a direct impact on 401(k) and profit-sharing plan operations. In 401(k) plans, the IRS limits how much more HCEs can contribute compared to non-highly compensated employees. If rank-and-file employees defer very little, HCEs may face contribution limits or refunds to maintain compliance with nondiscrimination standards.
In profit-sharing plans, the same principle applies to employer contributions. The plan must demonstrate that contribution rates for HCEs and NHCEs are proportionally fair.
Is a Cash Balance or Defined Benefit Plan Right For You?
Many employers address these challenges by adopting Safe Harbor 401(k) provisions, which automatically satisfy certain testing requirements. Under this design, the employer contributes either a matching formula or a 3% non-elective contribution for all employees, ensuring fairness while allowing HCEs to maximize their contributions.
In combination plan designs that include a cash balance plan, proper identification of HCEs becomes even more critical. Since these plans are tested together, accurate classification ensures that owners and key employees can receive higher contributions without violating IRS rules.
Managing HCE Status in Plan Design
Plan design strategies can help manage the effects of highly compensated employee classification. Employers who anticipate testing issues often use Safe Harbor features or cross-tested profit-sharing designs to balance contributions between employee groups. The goal is to maintain compliance while providing flexibility for higher contribution levels to owners and key employees.
A Safe Harbor 401(k) plan is one of the most effective ways to eliminate annual testing for deferrals. By committing to a 3% non-elective contribution or a specified match, the plan automatically passes the ADP and ACP tests.
In more advanced structures that include cash balance or defined benefit components, cross testing allows employers to demonstrate fairness based on projected retirement benefits rather than current contributions.
Proper plan coordination is essential to ensuring that both highly compensated and non-highly compensated employees benefit appropriately. Working with an experienced actuary or plan administrator helps employers structure contributions in a compliant and cost-effective way.
Common Mistakes and How to Avoid Them
Misidentifying highly compensated employees is one of the most common causes of retirement plan testing failures. Employers sometimes overlook family attribution rules or fail to update compensation thresholds annually. Errors in identifying ownership percentages or prior-year earnings can lead to incorrect testing results and costly corrections.
Another frequent mistake is failing to adjust plan design as the business grows. A company with few employees may have little trouble passing testing initially, but as compensation levels change, more employees may qualify as HCEs. Without proactive adjustments, such as adopting a Safe Harbor structure, the plan may fail nondiscrimination testing.
Employers can prevent these problems by conducting annual reviews of ownership, payroll data, and plan design. Keeping up with IRS thresholds and consulting with plan professionals ensures that testing remains accurate and manageable.
Key Takeaways for Employers
Understanding the definition of a highly compensated employee is essential for maintaining retirement plan compliance. Proper classification prevents plan failures and ensures that benefits remain fair across all employee groups.
Employers should review this status annually and consider strategies that minimize testing issues while maximizing contributions for key employees. Here are several key points to remember:
- Highly compensated employees include owners with more than five percent ownership.
- Employees earning over the IRS-set limit in the prior year are also considered HCEs.
- For 2025, the compensation threshold is $155,000 based on 2024 earnings.
- Employers may use the top 20 percent election to reduce the number of HCEs.
- Safe Harbor plan designs eliminate annual deferral testing for HCEs.
- Family ownership attribution applies when determining HCE status.
- Annual reviews ensure accurate classification and consistent compliance.
By following these principles, employers can maintain compliance and avoid costly plan corrections.
Final Thoughts
A highly compensated employee plays a central role in how retirement plans are tested and maintained under IRS rules. The classification ensures that benefits remain equitable and that plans do not favor higher-paid individuals unfairly. Understanding who qualifies as an HCE allows employers to design smarter, more efficient plans that meet both compliance and business objectives.
For employers, accurate identification of HCEs is not just a regulatory requirement—it is a strategic opportunity. Properly managed, it supports higher owner contributions, minimizes administrative burdens, and ensures long-term plan stability.
By staying informed and working with experienced plan professionals, businesses can create retirement structures that benefit everyone, from owners to employees, while maintaining full compliance with IRS standards.
