Executive Summary: Coverage as Retention: The Case for Variable Employer Contribution
TOS.03 — The Other Side#
Every component of employee compensation varies by employee value: salary, bonus, equity, paid leave, professional development budgets. Health coverage is the one exception where the benefits industry insists on uniformity. That insistence rests on a legal framework far narrower than commonly understood and on a cultural norm the employer-as-plan-sponsor model has never been required to maintain.
The operative legal constraints do not prohibit differentiated contribution by employee class. IRC Section 105(h) governs self-insured health plans and prohibits discrimination in favor of highly compensated individuals, defined as the five highest-paid officers, shareholders owning more than 10 percent, and the highest-paid 25 percent of employees. It does not prohibit offering richer benefits to senior project managers than to entry-level staff unless the favored class maps predominantly onto the HCI definition. IRC Section 125’s non-discrimination tests are oriented toward preventing disproportionate tax benefit accrual to executives and owners. ACA Section 2716, which would have extended comparable rules to fully insured plans, became effective on paper for plan years beginning September 23, 2010. The IRS issued Notice 2011-1 acknowledging that regulatory guidance was essential before compliance could be required. No implementing regulations have been issued as of 2026. No sanctions have been imposed.
The ICHRA final rules, codified at 26 CFR 54.9802-4 and effective January 1, 2020, already implement class-based variable contribution as a standard product feature. An employer can offer salaried project managers an ICHRA contribution of $1,200 per month and hourly laborers $500 per month. The class structure is explicit in the regulation. The regulatory framework the industry treats as prohibiting variable contribution built variable contribution into its most recent major product innovation.
The structural argument does not rest on regulatory permissiveness alone. A 30-person software firm pays senior engineers $180,000 and junior developers $90,000, allocates equity almost entirely to the people it most needs to retain, and spends $15,000 on conference attendance for senior staff and $3,000 for junior staff. Then it offers identical health benefits to both. The average annual employer contribution to single-coverage premiums reached approximately $7,583 in 2024 per KFF, making health benefits a material compensation component deployed as a fixed operating expense rather than a variable retention instrument.
The industry’s uniformity norm exists because bundled products are easier to apply uniformly, brokers find uniform plans simpler to service, and the cultural conflation of uniformity with fairness runs deep in the benefits profession. None of those rationales serves the employer or the employee.
The legal exposure is real but bounded. A self-insured plan offering substantially richer benefits to the five highest-paid officers fails the 105(h) benefits test. A cafeteria plan allowing key employees to divert a disproportionate share of pre-tax contributions fails the Section 125 key employee concentration test. The space between those constraints and full uniformity is large. An employer who sets contribution levels that vary by employment class, documented in the plan document, communicated transparently, and applied uniformly within each class, is exercising a settlor function under ERISA, not a fiduciary one. The employer who treats health benefits as a retention instrument has a legal framework that accommodates the approach. The industry’s reflexive caution does not.
