The key employee definition decides who counts toward three unrelated compliance tests a small or mid-size employer runs every year. For 2026, a key employee is anyone who meets at least one of three tests under Internal Revenue Code Section 416(i)(1)(A): an officer earning above $235,000, a business owner holding more than 5% of the company, or a more-than-1% owner earning above $150,000. Most payroll teams check this classification once, for a 401(k) top-heavy report, and never realize the same roster also feeds their Section 125 cafeteria plan testing and their group-term life insurance compliance. Here is how the 2026 thresholds work and why one classification touches three different benefits.
If you have not yet built out a Section 125 plan, start with our Section 125 cafeteria plan 2026 guide for the foundation, then come back here to see how key employee status affects it.
What Is a Key Employee Under Federal Tax Law?
A key employee is an employee who meets at least one of three tests under IRC Section 416(i)(1)(A): an officer earning above a set dollar threshold, a person who owns more than 5% of the business, or a person who owns more than 1% of the business and earns above a fixed $150,000. The definition started in the retirement plan top-heavy rules, but two other benefit provisions, the Section 125 cafeteria plan rules and the Section 79 group-term life insurance rules, were built directly on top of the same three-part test instead of writing separate definitions. An employee only has to satisfy one of the three tests to be classified a key employee. Meeting more than one test does not change the outcome, since the label itself is binary and does not stack.
How Much Does an Officer Have to Earn to Be a Key Employee in 2026?
An officer must have compensation above $235,000 for 2026 to meet the officer test, up from $230,000 for 2025 under IRS Notice 2025-67. This test looks at the prior year's pay, so an employee's actual 2025 W-2 compensation determines their 2026 key employee status, not their current-year pay in progress. Job title alone does not decide this test. The IRS looks at real administrative or executive authority, so a person with an inflated title but no genuine decision-making power can fail the officer test, while someone with a lesser title but real authority can pass it.
A statutory cap limits how many people the officer test alone can classify as key employees. No more than 50 employees, or the greater of 3 employees or 10% of the workforce rounded up if the company is smaller, can be counted under this test, regardless of how many officers actually clear the $235,000 threshold.
Is Every 5% Business Owner Automatically a Key Employee?
Yes. A person who owns more than 5% of the business, counting both direct ownership and family attribution under IRC Section 318, is a key employee at any compensation level, including $0. This test has no dollar threshold at all. Attribution generally reaches a spouse, children, grandchildren, and parents, so a business owner's adult child working a modest-salary job can become a key employee purely through the parent's ownership stake, even though the child's own paycheck falls nowhere near either compensation test.
| Test | 2026 threshold | Compensation required? |
|---|---|---|
| Officer test | $235,000 | Yes, above the threshold |
| More-than-5% owner | No dollar limit | No, any amount including $0 |
| More-than-1% owner | $150,000 (fixed, not indexed) | Yes, above $150,000 |
Is a Key Employee the Same as a Highly Compensated Employee?
No. A highly compensated employee, or HCE, is defined under a separate statute, IRC Section 414(q), using only a compensation threshold with no officer duties or ownership requirement, set at $160,000 for 2026 based on 2025 pay. Every key employee also meets the HCE definition, since clearing any key employee test almost always means clearing the lower HCE pay bar too, but the reverse is not true. A well-paid engineer earning $175,000 with no officer title and no ownership stake is an HCE for testing purposes but is never a key employee, and the two labels drive different compliance obligations.
How Does Key Employee Status Affect a Section 125 Cafeteria Plan?
IRC Section 125(b)(2) requires that the nontaxable benefits provided to key employees not exceed 25% of the total nontaxable benefits provided to every employee under the plan. The test is a simple ratio: total pre-tax elections by key employees, divided by total pre-tax elections by the entire plan. A 60-employee company running $480,000 in total annual pre-tax elections, with three key employees electing a combined $132,000, has a 27.5% concentration ratio, which fails the 25% limit by $12,000. The key employees would need to reduce their combined elections to $120,000 or below, or the $12,000 excess becomes taxable wages for those key employees specifically, while every other employee keeps full pre-tax treatment regardless. This concentration test runs independently of a plan's separate eligibility and benefits nondiscrimination tests, covered in our Section 125 nondiscrimination testing guide, and a plan can pass those tests cleanly while still failing this one.
How Does Key Employee Status Affect Group-Term Life Insurance?
Under IRC Section 79(d), a group-term life insurance plan that discriminates in favor of key employees strips those key employees of the entire $50,000 tax-free exclusion described in our group-term life insurance imputed income guide. A key employee caught in a discriminatory plan must include the greater of the actual premium cost or the IRS Table I cost of their full coverage in taxable income, not just the portion above $50,000 the way a non-key employee's excess coverage is taxed. Non-key employees keep their full $50,000 exclusion even when the same plan is found discriminatory, since Section 79(d) targets only the employees the discrimination was designed to benefit.
How Does Key Employee Status Affect a 401(k) Plan?
A 401(k) plan becomes top-heavy under IRC Section 416 when key employees hold more than 60% of total account balances across the entire plan as of the determination date. A plan that crosses this line generally must provide a minimum employer contribution, typically 3% of compensation, to every non-key employee still on payroll at year-end, regardless of whether that employee deferred anything themselves. Many safe harbor 401(k) designs are deemed to satisfy this minimum automatically, which is one reason companies with a concentrated ownership group, the kind covered in our simple cafeteria plan safe harbor guide, often choose a safe harbor structure from the start.
