Highly Compensated Employee Definition 2026: The $160,000 Threshold Explained

• The 2026 HCE compensation threshold is $160,000, unchanged from 2025, the first flat year after several straight increases, per IRS Notice 2025-67.
• The ownership prong of the HCE test uses a two-year lookback, current year or preceding year, wider than the single-year window most other benefit ownership tests use.
• Employers can elect under IRC §414(q)(1)(B)(ii) to limit compensation-based HCE status to the top-paid 20% of the workforce, a choice most companies never make.
• Every key employee is automatically an HCE, but most HCEs, roughly everyone earning above $160,000 with no ownership stake or officer title, are never key employees.
• The Section 125 eligibility test and the Section 125 benefits test both run on the HCE definition, and a plan can pass one while failing the other.

A 41-year-old regional sales director at a 90-employee software company earned $168,000 in 2025. That single number, on its own, makes her a highly compensated employee for 2026 under IRC Section 414(q), a classification with no connection to her job title, her ownership stake, or anything her employer decided about her role. Two entirely different compliance tests, one for the company's Section 125 cafeteria plan and one for its 401(k), now measure her benefits and her retirement deferrals against everyone below that line. Here is exactly how the HCE definition works for 2026, how it differs from the separate key employee test, and where the two Section 125 tests it feeds most often get confused.

What is a highly compensated employee under federal tax law?

A highly compensated employee is an employee who meets either of two independent tests written into IRC Section 414(q): a compensation test based on prior-year pay above an indexed dollar threshold, or an ownership test based on owning more than 5% of the business at any time during the current or preceding year. An employee only needs to satisfy one of the two tests to be an HCE, and satisfying both does not create a different or stronger classification, since HCE status itself is a single binary label. Congress originally wrote the HCE definition for 401(k) and other qualified retirement plan testing, then Section 125(e) imported the identical definition for cafeteria plan nondiscrimination testing rather than writing a separate compensation rule from scratch.

How much do you have to earn to be an HCE in 2026?

An employee is an HCE under the compensation test if their prior-year pay exceeded $160,000, the 2026 threshold set by the IRS under IRC Section 414(q)(1)(B) and confirmed in IRS Notice 2025-67. This figure adjusts for inflation in $5,000 increments, and 2026 marks the first year in several consecutive cycles the number did not move up from the prior year, since cumulative inflation had not yet crossed the next $5,000 rounding point. Compensation for this test generally includes salary, bonus, commission, and most taxable fringe benefits, the same broad definition used across the Section 415 and key employee rules, and it is measured using the lookback year, not current-year pay still being earned.

Does owning part of the business make you an HCE?

A person who owned more than 5% of the business at any time during the current plan year or the immediately preceding year is an HCE under IRC Section 414(q)(1)(A), independent of how much or how little compensation they actually received. This ownership test uses the modified attribution rules that also apply to the key employee ownership test, reaching stock or capital interest held by a spouse, child, parent, or grandparent as if the employee held it directly. The two-year lookback window is wider than the single-year determination date used for the key employee ownership test, meaning a person who sold down from 7% to 3% ownership last year is still an HCE for the current year purely because of where their stake stood twelve months earlier.

What is the top-paid group election?

The top-paid group election under IRC Section 414(q)(1)(B)(ii) allows an employer to limit HCE status among employees who clear the compensation threshold to only those who also rank in the top 20% of the workforce by pay, rather than treating everyone above $160,000 as an HCE automatically. A company with 200 employees where 55 people earn above $160,000 could, with this election in place, classify only the top 40 earners, the top 20% of the full 200-person workforce, as HCEs under the compensation prong. The election has no effect on the ownership test, so a 6% owner earning $95,000 remains an HCE regardless of where their pay ranks, and once an employer adopts the election it must be written into the plan document and applied consistently across the company's benefit plans.

How is an HCE different from a key employee?

A key employee is defined under a completely separate statute, IRC Section 416(i), requiring an officer title paired with pay above $235,000 for 2026, a more-than-5% ownership stake at any compensation level, or a more-than-1% ownership stake paired with pay above a fixed $150,000. Every key employee automatically satisfies the HCE definition too, since clearing any of the three key employee tests virtually always clears the lower $160,000 HCE compensation bar, but the reverse is not true. A well-paid engineer or account executive earning $175,000 with no officer title and no ownership stake is an HCE for every test that uses the HCE definition, yet is never a key employee, and the two labels drive entirely different sets of compliance obligations across the same benefits program.

How does HCE status affect the Section 125 eligibility test?

The Section 125 eligibility test under IRC Section 125(b)(1) checks whether a cafeteria plan discriminates in favor of highly compensated individuals in who is allowed to participate, looking at eligibility rules like waiting periods, minimum hours, and job classifications rather than actual dollar amounts elected. A plan generally passes this test automatically if it uses reasonable classifications, such as all full-time employees after 30 days of service, that do not single out HCEs by name or by a classification that functions as a proxy for HCE status. This test runs independently of how much any individual HCE actually elects to contribute, since it measures the structure of who can join the plan rather than what participants choose to do once they are eligible.

How does the Section 125 benefits test differ from the eligibility test?

The Section 125 benefits test under IRC Section 125(b)(2) compares the average nontaxable benefits actually received by highly compensated participants against the average nontaxable benefits received by everyone else in the plan, rather than looking at eligibility rules the way the first test does. A cafeteria plan can pass the eligibility test cleanly, offering identical enrollment terms to every full-time employee, and still fail the benefits test if HCEs simply choose to elect richer benefits at a higher average dollar amount than the rest of the workforce. This is a different measurement than the 25% key employee concentration test, which only looks at the narrower statutory key employee group rather than the full HCE population, so a plan can fail the benefits test on its broader HCE population while still passing the key employee concentration test cleanly.

Worked example: the Section 125 benefits test

A 90-employee software company has 18 employees who qualify as HCEs under the $160,000 compensation test. Those 18 HCEs elect an average of $9,200 in annual nontaxable Section 125 benefits, while the remaining 72 non-HCE employees elect an average of $5,100. Regulators and plan administrators generally look for parity in the average benefit received rather than a fixed statutory ratio the way the 25% key employee test uses, so a gap this size, roughly 80% higher average benefits for the HCE group, is the kind of disparity that draws scrutiny during testing and often points to a plan design issue rather than any single employee's election choice.

We assumed passing our 401(k) ADP test meant our benefits were fine everywhere else. Nobody had actually run the Section 125 benefits test separately in three years, and the gap between what our directors elected and what everyone else elected had grown every year without anyone noticing.

How does HCE status affect a 401(k) plan's ADP test?

Under IRC Section 401(k)(3), the Actual Deferral Percentage test caps how much more HCEs can defer on average, as a percentage of pay, compared to non-HCEs, using a formula that allows the HCE average to reach the lesser of the non-HCE average plus 2 percentage points or twice the non-HCE average, whichever produces the smaller ceiling. A plan that fails this test generally must either refund excess contributions to HCEs, which creates taxable income for those employees, or make an additional qualified nonelective contribution to non-HCEs to close the gap, and most employers who can choose prefer the refund route since it does not add a permanent new cost to the plan.

Worked example: the ADP test

The same 90-employee software company has a non-HCE average deferral rate of 4.1% for the year. Under the ADP formula, the HCE ceiling is the lesser of 6.1%, the non-HCE average plus 2 points, or 8.2%, twice the non-HCE average, so the applicable cap is 6.1%. If the company's 18 HCEs actually averaged 7.4% in deferrals, the plan fails the test by 1.3 percentage points and must correct the excess before the following March 15 to avoid a 10% excise tax on the uncorrected amount under IRC Section 4979.

When is HCE status actually determined?

The compensation test runs on a prior-year lookback, so 2025 pay determines HCE status for the 2026 plan year rather than 2026 compensation still being earned during the year in question. The ownership test looks at ownership percentage across a two-year window, the current year and the immediately preceding year combined, rather than a single lookback year, since ownership does not carry the same kind of trailing annual record a salary does. A new hire with no 2025 W-2 on file generally is not treated as an HCE under the compensation test for their first year, regardless of the salary they are hired at, unless that new hire is also a more-than-5% owner, in which case the ownership test applies immediately based on current ownership.

Common HCE classification mistakes

The most common mistake is testing HCE status once at the start of a plan year and never rechecking it after a mid-year promotion, bonus, or ownership change moves someone across the $160,000 line or the 5% ownership threshold. The second is assuming that passing the 401(k) ADP test automatically means the company's Section 125 plan is also fine, when the two tests measure entirely different benefits using the same HCE roster but different math. The third is confusing HCE status with key employee status, applying the wrong compensation threshold or the wrong test to an employee who clears one classification but not the other.

How to identify and manage HCE compliance correctly

1. Pull every employee's prior-year W-2 compensation. Compare it against the current year's $160,000 threshold to build the compensation-test list.
2. Flag every owner above 5%, current or prior year. The two-year lookback catches owners who reduced their stake within the last twelve months.
3. Decide whether to make the top-paid group election. Document the choice in the plan and apply it consistently once made.
4. Run the Section 125 eligibility and benefits tests separately. A plan can pass one and fail the other on the identical HCE roster.
5. Check the 401(k) ADP test against the same list. The formula compares HCE and non-HCE average deferral rates, not raw dollars.
6. Re-run the entire determination every plan year. A raise, bonus, or ownership change can move someone onto or off the list.
