Executive Summary: ICHRA Mechanics: How Individual Coverage HRAs Actually Work and Where They Break
LFP-08.01, The Hybrid Frontier#
The individual coverage health reimbursement arrangement is a reimbursement mechanism, not a risk-bearing structure. Finalized under 26 CFR 54.9802-4 and available beginning January 1, 2020, the ICHRA allows employers of any size to reimburse employees tax-free for individual market premiums up to a defined monthly amount. No shared risk. No claims fund. No stop loss. The employer sets a number; the employee buys a plan in the individual market; the employer reimburses substantiated expenses. What the employee receives in exchange depends entirely on what the individual market in their specific county provides.
The regulatory mechanics have material financial consequences. When an employer offers an ICHRA that meets ACA affordability standards, meaning the employee’s residual share of the lowest-cost silver plan does not exceed 9.02% of household income for 2025, the employee cannot claim marketplace premium tax credits. This creates a trap for lower-income employees: an ICHRA reimbursement of $100 per month that renders a $350 remaining premium “unaffordable” allows the employee to opt out and access subsidies that might cover $250 to $300 per month. The ICHRA in that scenario is worse than no ICHRA at all. Employers who set ICHRA amounts based on budget without mapping them to marketplace costs and employee income levels in specific geographies are producing this outcome across their workforces.
Geographic coverage quality varies substantially. For 2025, 97% of marketplace enrollees nationally have access to three or more insurance carriers in their county, a recovery from 2017 and 2018 turbulence driven by enhanced premium tax credits. That aggregate improvement concentrates in metropolitan markets. Eight states lost on-exchange carrier offerings for 2025 relative to 2024. Aetna’s exit from the individual insurance market, covering approximately 1 million enrollees across 17 states, is the most significant single market exit since the ACA’s implementation. The enhanced premium tax credits that stabilized the market expire at the end of 2025; if not extended, substantial premium increases and carrier exits in less profitable markets are projected.
ICHRA also shifts the plan selection burden to the employee in ways that group coverage does not. The employee reviews dozens of marketplace options, selects a plan, pays the premium directly, submits reimbursement documentation, and manages their own EOBs and billing disputes. A TPA adding ICHRA administration without systematically evaluating marketplace adequacy by county and employee income level for each employer it serves is offering a mechanism whose delivery it does not understand.
