Every arrangement described so far in this series shares an assumption so basic it usually goes unstated: that the employer chooses the health plan. The employer picks a carrier, selects the plan designs, and hands employees a menu someone else assembled. The Individual Coverage Health Reimbursement Arrangement — ICHRA, pronounced "ick-rah" by people who say it often — throws that assumption out. Under an ICHRA, the employer chooses a budget, not a plan. It gives each employee a defined sum of tax-free money, the employee buys whatever individual-market policy suits them, and the employer reimburses the premium. The employer sets the dollars; the employee makes the coverage decision.
This is a genuinely different model — defined contribution instead of defined benefit, the same shift that decades ago turned pensions into 401(k)s — and it is new. ICHRA has existed only since 2020. Whether it becomes a major pillar of employer coverage or a useful niche tool is still being decided in real time, and the answer depends partly on a subsidy fight in Congress that was unresolved as this was written.
Where ICHRA came from
The regulatory path to ICHRA runs through a wonky but important fight about whether employers could just hand employees cash for individual coverage. For years, the informal practice of "employer payment plans" — reimbursing employees for individual policies — existed in a gray zone. Then, in 2013, federal regulators issued guidance making clear that a standalone arrangement reimbursing individual premiums violated the ACA's insurance-market rules, because such an arrangement was itself a group health plan that failed to meet requirements like the ban on annual limits. Employers who had been quietly reimbursing individual coverage were told to stop, on pain of steep per-employee excise penalties. The door closed.
It reopened in stages. The 21st Century Cures Act of 2016 cracked it for the smallest employers by creating the QSEHRA, covered separately in this series. Then, acting on a 2017 executive order directing agencies to expand access to HRAs, the Departments of Labor, Treasury, and Health and Human Services jointly issued a final rule on June 13, 2019 — "Health Reimbursement Arrangements and Other Account-Based Group Health Plans" — that created the ICHRA and made it available for plan years beginning on or after January 1, 2020. The rule threaded the needle that had sunk the earlier employer payment plans: an ICHRA is permitted specifically because it requires each covered employee to be enrolled in individual health insurance that independently satisfies the ACA's market rules. The reimbursement arrangement integrates with real ACA-compliant individual coverage, which is what the 2013 guidance said standalone reimbursement lacked.
How an ICHRA actually works
The mechanics are straightforward, and their simplicity is much of the appeal. The employer decides how much it will reimburse each eligible employee — monthly or annually — and unlike almost every other tax-advantaged health benefit, there is no federal cap on the amount. An employer can offer $300 a month or $2,000 a month; the ceiling is the employer's budget, not the IRS. Employees then go to the individual market — through the ACA exchange or off-exchange — and buy a policy. They submit proof of coverage and proof of premium, and the employer reimburses them, tax-free, up to their allowance. If a policy costs less than the allowance, the employer keeps the difference (or the arrangement can let the remainder cover other qualified medical expenses, depending on design); if it costs more, the employee pays the gap.
Two hard rules define the arrangement. First, every employee reimbursed through an ICHRA must actually be enrolled in individual coverage or Medicare — an ICHRA cannot reimburse premiums for a spouse's group plan or for a health-sharing ministry, because those are not individual insurance meeting the rule's requirements. Employers must verify enrollment. Second, an employer cannot offer the same class of employees a choice between the ICHRA and a traditional group plan. Within a given class, it is one or the other. This "no same-class choice" rule exists to prevent employers from steering their sickest employees into the individual market while keeping healthy ones on the group plan — a form of risk-dumping the regulators specifically wrote the rule to block.
The class system: flexibility with guardrails
The ICHRA rule's most distinctive feature is that it lets an employer treat different groups of employees differently, but only along lines the rule pre-defines. The regulation lists permitted employee classes — full-time employees, part-time employees, seasonal employees, salaried versus hourly, employees in different geographic rating areas, employees covered by a collective bargaining agreement, employees in a waiting period, temporary staffing employees, and a few others, along with combinations of these.
An employer can offer a traditional group plan to one permitted class and an ICHRA to another — say, a group plan for salaried headquarters staff and an ICHRA for hourly field workers in scattered locations. Within a single class, however, the offer must be uniform, with two allowed exceptions: the reimbursement amount may increase with the employee's age (tracking the reality that older people face higher individual premiums), and it may increase with the number of dependents covered. To keep employers from gaming the classes to cherry-pick risk, the rule attaches minimum class-size requirements when an employer offers some classes a group plan and other classes an ICHRA — the smaller the employer, the larger the minimum ICHRA class must be, scaling up for bigger companies. The design goal throughout is flexibility for legitimate business reasons, fenced by rules that stop the flexibility from becoming a tool for dumping expensive employees.
The affordability trap employers must watch
For a large employer — an "applicable large employer" with 50 or more full-time-equivalent employees, subject to the ACA's employer mandate — an ICHRA is treated as an offer of coverage that can satisfy the mandate. But it satisfies the mandate only if the ICHRA is affordable, and the affordability math for an ICHRA is its own particular puzzle.
Affordability turns on whether the employee's required contribution for a benchmark plan — the lowest-cost silver plan available to that employee in their rating area, for self-only coverage — comes in at or below the ACA's annually indexed affordability percentage of the employee's income, after applying the ICHRA reimbursement. For the 2026 plan year that percentage is 9.96 percent, the highest it has ever been, up from 9.02 percent in 2025. In plainer terms: the employer must contribute enough through the ICHRA that, after the reimbursement, the employee is not left paying more than 9.96 percent of income for that benchmark silver plan. If the ICHRA falls short and an employee ends up buying subsidized exchange coverage, the large employer can face a shared-responsibility penalty — for 2026, the relevant per-employee penalty runs to $5,010 annually. An employer offering an ICHRA to satisfy the mandate has to size the contribution against benchmark premiums that vary by geography and age, which is more involved than the flat-percentage math of a traditional plan.
There is a second interaction that cuts the other way and matters to employees. Being offered an affordable ICHRA makes an employee ineligible for a premium tax credit on the exchange — the employee must take the ICHRA money instead. If the ICHRA is unaffordable, the employee may decline it and claim the subsidy instead, but cannot do both. This trade-off sat under a large cloud as this was written, because the enhanced premium tax credits that expanded exchange subsidies were scheduled to expire at the end of 2025 unless Congress extended them. If they lapse, exchange coverage becomes more expensive for many people, which changes the calculus of whether an ICHRA's fixed contribution is generous or thin — an unusually large amount of ICHRA's real-world value hinges on a subsidy decision outside anyone's control. Anyone weighing an ICHRA in 2026 should confirm the current status of those subsidies before modeling the numbers.
Who ICHRA fits
ICHRA tends to make sense for a handful of recognizable situations. It fits an employer with a geographically scattered workforce, where no single group plan network serves everyone well but the individual market offers local options in each area. It fits an employer that wants absolute cost predictability — a defined monthly contribution that will not surprise it at renewal the way a fully insured premium can, because the employer's exposure is capped at the dollars it chose to offer. It fits an employer that wants to give employees real choice of plan and network rather than a curated group menu. And it can fit an employer that has struggled to get a competitive group quote at all, particularly a small or mid-sized business whose group renewals keep climbing.
It fits poorly where the local individual market is thin or expensive, where employees value the simplicity of a single employer-chosen plan over choice, or where the administrative work of verifying individual enrollment and managing reimbursements outweighs the benefit — though a growing set of administrators now handle that machinery for a fee. And its attractiveness genuinely depends on the individual-market and subsidy environment, which is more politically volatile than the ground under traditional group coverage. ICHRA is a real and powerful tool, newer and less settled than the alternatives, and it rewards employers who take the time to check whether the individual market their employees would actually shop in is one worth sending them into.
