How does ICHRA work? A plain-English guide for employers.

Group health insurance cost employers an average of $8,951 per employee for single coverage in 2024 (KFF) — and that number has risen in almost every year for two decades. Here is how ICHRA works: the employer sets a fixed monthly reimbursement allowance, the employee purchases their own ACA-compliant individual health plan, and the employer reimburses documented premium costs up to that allowance, tax-free. ICHRA adoption grew 29% in 2024 (HRA Council). The reason is straightforward: the carrier's renewal letter stops being the employer's problem.

Key takeaways

• With an ICHRA, the employer sets a fixed monthly tax-free reimbursement allowance. The employee buys their own ACA-compliant individual plan. The employer reimburses documented premium costs up to the allowance — never more.
• ICHRA allowances are excluded from employee income under IRC §106. Contributions are deductible to the employer. Allowances can vary by employee class — age, family size, and work classification — which a single group plan cannot replicate.
• ICHRAs are available to employers of any size. For ALEs (50+ FTEs), a properly designed ICHRA satisfies the ACA employer mandate. For small employers, no participation requirement applies.

What is an ICHRA?

An ICHRA (Individual Coverage Health Reimbursement Arrangement) is an employer-funded benefit that reimburses employees for individual health insurance premiums on a tax-free basis. The employer sets a monthly allowance; the employee buys their own plan; the employer reimburses up to that allowance. Available to employers of any size since January 1, 2020, under a joint final rule from the Departments of Treasury, Labor, and HHS (84 FR 28888), the ICHRA eliminated the prior ban on reimbursing individual market premiums. The legal authority is IRC §105 and §106. There is no federal cap on employer contributions and no minimum participation requirement. The ICHRA is not insurance — it is a reimbursement arrangement: the employer funds the allowance, and the employee selects and owns the coverage.

How does ICHRA work — 3 steps

1. Employer sets the monthly allowance. The employer decides how much to contribute per employee per month. There is no IRS-imposed ceiling. Allowances can vary by employee class under 26 CFR §54.9802-2 — full-time versus part-time, salaried versus hourly, geographic rating area, age, and family size are all permitted differentiators. An employer with 25 employees might set $500 per month for full-time employees, $250 for part-time, and $150 additional per dependent — all within a single ICHRA design. The employer's annual liability is exactly the aggregate allowance times enrollment. Nothing more.
2. Employee purchases an individual plan. The employee shops the ACA marketplace or a private exchange for a plan that meets Minimum Essential Coverage (MEC) standards. Any ACA-compliant plan qualifies — bronze, silver, gold, or platinum. The employee owns the plan. If they leave the employer, the coverage stays with them — no COBRA election required, no coverage gap. Employees cannot satisfy the ICHRA enrollment requirement using coverage under a spouse's or parent's group plan; they must hold their own individual market plan.
3. Employee submits documentation; employer reimburses. The employee submits proof of enrollment and the premium amount to the ICHRA administrator. The administrator verifies documentation and reimburses up to the monthly allowance. Concrete example: employer sets $450 per month. Employee's silver plan costs $520 per month. Employer reimburses $450 tax-free under IRC §106. Employee pays $70 out-of-pocket. The $450 reimbursement does not appear in W-2 Box 1, Box 3, or Box 5. The $70 employee share is after-tax unless a Section 125 cafeteria plan→ converts it to a pre-tax salary reduction.

Key ICHRA rules employers must know

The ICHRA plan operates under rules set by the 2019 joint final rule (84 FR 28888) and enforced by the IRS and HHS. These ICHRA rules determine who can participate, how allowances can be structured, and what compliance obligations the employer carries. Getting them wrong can reclassify the ICHRA as a group health plan — triggering ACA market reform requirements that make the arrangement non-compliant.

• Individual coverage is required. Employees must hold their own individual market health insurance plan. Coverage under a spouse's or parent's group plan does not qualify for ICHRA reimbursement.
• No concurrent group plan for the same class. An employer cannot offer both an ICHRA and a traditional group health plan to the same employee class in the same plan year. Different classes may receive different benefit types.
• Allowance differentiation only within 11 IRS classes. Variable allowances are permitted only using the classes defined in 26 CFR §54.9802-2 — full-time vs. part-time, salaried vs. hourly, geographic rating area, age (up to a 3:1 ratio), family size, and collectively bargained employees, among others.
• ALEs must run an affordability test annually. For employers with 50 or more FTEs, the employee's net cost (lowest silver plan premium minus the ICHRA allowance) must not exceed 9.02% of household income under the 2026 rate-of-pay safe harbor. Failure triggers employer mandate penalty exposure.
• Opt-out notice is required at enrollment. An employee offered an affordable ICHRA loses premium tax credit eligibility for that plan year. Employers must notify employees of this before enrollment so they can make an informed opt-out decision.
• Reimbursements require documented proof of coverage. Employees must submit proof of individual coverage with each reimbursement request. Undocumented reimbursements lose their IRC §106 tax-free status.

Benefits for employers

Traditional group health insurance cost employers an average of $6,266 per year per employee for single coverage in 2024 — 70% of the $8,951 KFF total premium. Family coverage ran $18,904 per employee per year at a 74% employer share. For a 25-person company offering single coverage, that is $156,650 per year before the next carrier renewal, which averaged a 6% increase in 2024.

Beyond cost control, ICHRAs eliminate the participation requirement that routinely blocks small employers from qualifying for group coverage. There is no medical underwriting at the employer level, no minimum group size, and no requirement that a majority of employees participate. Employers running self-funded plans with large ongoing claims can exit that exposure entirely and cap their annual liability at the aggregate ICHRA allowance they set. For a full comparison of small business health insurance options including ICHRA→, the 2026 buyer's guide benchmarks each structure by employer size.

For ALEs subject to the ACA employer mandate, the ICHRA satisfies the mandate when the employee's net premium cost — the lowest-cost silver plan in their rating area minus the ICHRA allowance — does not exceed 9.02% of household income under the 2026 rate-of-pay safe harbor. The affordability calculation must be run annually for each rating area where the employer has employees.

Benefits for employees

The most practical employee benefit is portability. An individual market plan travels with the employee when they change jobs, take a leave, or shift to part-time status. There is no COBRA window to manage and no waiting for a new employer's group plan to take effect.

• Personal plan selection. Employees choose the network, deductible, and providers that fit their household — not a plan a committee selected for the median employee. A 28-year-old in good health and a 47-year-old managing a chronic condition should not be on the same plan.
• Tax-free reimbursement. The employer's allowance is excluded from W-2 Box 1, Box 3, and Box 5 income under IRC §106. No federal income tax, no FICA on the reimbursed amount.
• HSA compatibility. An employee enrolled in an HSA-eligible HDHP can contribute to a Health Savings Account alongside the ICHRA if the ICHRA is limited to reimbursing premiums and preventive care. The 2026 limits are covered in the HSA contribution limits guide→.
• Plan continuity across jobs. Mid-year deductible credits are not reset when an employee changes employers and both use ICHRA to reimburse the same individual market plan.

One trade-off worth communicating: an employee offered an ICHRA deemed "affordable" under ACA standards cannot claim the premium tax credit on the federal exchange for that plan year. Employees in lower-wage positions should compare the ICHRA allowance against the subsidy they would receive by opting out. The opt-out right is built into the ICHRA rules and must be communicated at enrollment.

Benefits for brokers

ICHRAs open a defined contribution market that did not exist before 2020. Employers that previously could not qualify for group coverage become viable clients once ICHRA is on the menu.

• Expanded addressable market. Any employer with W-2 employees can establish an ICHRA, including those with two to ten employees priced out of the group market. Brokers who can model an ICHRA allowance against the employee's marketplace options have a structured value proposition for this segment.
• Individual plan placement. ICHRA-enrolled employees need individual market plans. Brokers licensed on the individual market can assist employees with plan selection and earn commissions on each placement — separate from the ICHRA administration fee.
• Compliance advisory value. Affordability calculations, ACA mandate compliance, class-based allowance design, and the interaction with premium tax credits are complex enough that brokers who understand the mechanics become indispensable to clients navigating the group-to-ICHRA transition.
• Section 125 add-on revenue. Employers running an ICHRA without a §125 cafeteria plan are leaving pre-tax savings uncaptured on every payroll. Brokers who introduce the §125 wrap add a second revenue stream and a measurable client benefit in the same conversation. The Benecor broker partner program→ is structured around this placement sequence.

ICHRA pros and cons

The ICHRA's advantages are structural — cost certainty, no participation requirements, and genuine plan flexibility. The disadvantages are manageable, but most employers who run into problems launched without understanding all the ICHRA rules or skipped the §125 layer.

The largest correctable disadvantage is the after-tax employee contribution gap. An ICHRA plan without a Section 125 cafeteria plan→ wrapper leaves both employer and employee FICA uncaptured every payroll. Adding the §125 layer eliminates that gap and makes the ICHRA structure tax-equivalent to a fully administered group plan.

ICHRA vs. QSEHRA: which one fits?

Both ICHRAs and Qualified Small Employer HRAs (QSEHRAs) let employers reimburse individual market premiums tax-free. The structural differences are decisive for employers near the 50-FTE line or with varied employee populations.

For employers under 50 FTEs who want simplicity and a moderate allowance under the contribution ceiling, the QSEHRA is the lower-friction option. For employers who need budget flexibility above the QSEHRA cap, who are ALEs subject to the employer mandate, or who have meaningfully different employee classes, the ICHRA is the correct structure. Employers near the 50-FTE line should start with an ICHRA — migrating from QSEHRA to ICHRA after crossing the headcount threshold requires reissuing plan documents and resetting employee elections mid-cycle.

How Benecor Health simplifies ICHRA

Most ICHRA administrators handle the reimbursement platform: documentation collection, eligibility verification, and allowance tracking. What they typically do not build is the Section 125 cafeteria plan that converts the employee's above-allowance premium contribution from after-tax to pre-tax. That gap leaves FICA savings uncaptured on every payroll for both the employer and employee. Benecor administers both the §125 plan document and the ICHRA integration under a single engagement — no vendor handoff at the payroll boundary, no coordination gap. The fee is $35 per enrolled employee per month. Employers receive a written, payroll-specific projection within 48 hours of submitting two months of de-identified payroll data. Brokers placing ICHRA clients can partner with Benecor to add the §125 wrap as a standalone engagement and earn the administration override. Schedule a call→ to get started.
