ICHRA Explained: How Employer Health Reimbursement Works

A growing share of small and mid-sized employers have stopped offering a ready-made group plan and moved to a different model entirely: the employer sets a monthly dollar amount, the employee buys the individual health plan that suits them, and the premium gets reimbursed from that amount tax-free. This is the ICHRA — the Individual Coverage Health Reimbursement Arrangement — and it redraws the lines between who pays and who chooses.

This guide explains how the money flows tax-free, who benefits and who does not, the eleven employee classes the law permits, the 10.22% affordability test for 2027, and the rule that matters most: an affordable ICHRA offer disqualifies you from premium tax credits.

What an ICHRA actually is

An ICHRA is not insurance: there is no medical coverage in it, no doctor network, no claims file. It is a funding mechanism: the employer defines a monthly allowance, the employee buys their own ACA-compliant individual plan — through the Marketplace or directly from a carrier — and the premium is reimbursed from the allowance, excluded from income and payroll taxes, against proof that coverage is in force. There is no federal cap on the allowance amount, and unspent allowance never becomes cash in the paycheck.

The essential difference from a group plan: here the employee chooses the plan — the metal level, the network, the carrier — and the employer funds without deciding.

How the money flows, tax-free

1. The employer sets a monthly allowance, by employee class
2. The employee purchases a qualified individual plan and pays the premium
3. The arrangement's administrator substantiates that qualifying coverage is in force, monthly
4. Reimbursement reaches the employee tax-free, up to the allowance

Anything above the allowance stays in the employee's pocket — the arrangement reimburses; it does not purchase on your behalf.

The eleven employee classes

Employers may not differentiate staff arbitrarily, but the rules allow different allowances across eleven defined classes: full-time employees, part-time, seasonal, salaried, hourly, temporary workers, employees in a single geographic area, employees in a similar employment position, those covered by a collective bargaining agreement, employees awaiting entry into a group plan, and pre-Medicare-eligible retirees.

Within each class, terms must be uniform — a manager cannot receive double the allowance of a peer in the same class. That is the system's main safety valve, and the source of most employer errors.

The affordability test — 10.22% for 2027

For each employee, the offer must be affordable: the allowance has to be large enough that the employee's remaining share of the lowest-cost silver plan in their area (for self-only coverage) stays within 10.22% of income for 2027. The test is mandatory, and the rules provide safe-harbor formulas using assumed income figures, so an employer does not need to know actual salaries to run it.

Why the test matters leads directly to the rule below.

The rule that matters most: an affordable offer cancels premium tax credits

As long as the ICHRA offer is affordable for you, you are ineligible for federal premium tax credits on the Marketplace — the law does not allow both benefits for the same person. If the offer is not affordable for you, you may decline it each year and keep your subsidy eligibility.

So the question every employee should answer before signing: after subtracting the allowance, is my share of the cheapest silver premium below 10.22% of my income? If yes, the offer is affordable and, realistically, the allowance will usually beat the subsidy. If no, declining the ICHRA and keeping the subsidy may be financially better. Decide with arithmetic, not with impressions.

Opting out, and the ICHRA enrollment window

Employees are free to decline the arrangement — generally with an annual opt-out opportunity (limited exceptions exist). And here is the fact most people miss: an ICHRA offer is a qualifying event that opens a special enrollment period on the individual market, outside regular open enrollment — the employee can enroll in (or switch to) individual coverage when the arrangement starts or is materially changed. If you have been waiting for open enrollment because you assumed there was no other door, your door is already open.

What the employer notice must say

Employers cannot launch an ICHRA silently. The rules require a written notice to each eligible employee — generally at least 90 days before the start of each plan year — stating the allowance amount, how to use the arrangement, and a plain-language warning that accepting the ICHRA may disqualify the employee from premium tax credits. A missing or late notice carries financial consequences for the employer. If you are an employee who received no notice, ask for it in writing before deciding anything.

ICHRA vs QSEHRA vs group coverage

	ICHRA	QSEHRA	Group plan
Who can offer it?	Any employer, any size	Small employers only, with no group plan	Any employer willing to fund it
Funding cap	No federal dollar cap	Annual statutory dollar caps	None — the full group premium is the cost
Who picks the plan?	The employee, on the individual market	The employee, on the individual market	The employer, for everyone
Variation between employees	Across 11 legal classes	Very limited (age-based, within bounds)	Limited
With Medicare	Generally not qualifying coverage for those 65+ — designed for the under-65 market	Can reimburse Medicare premiums	Covers participants of any age
Combined with premium tax credits?	No, when the offer is affordable	Own rules that can reduce credits	Outside the subsidy system entirely

Choosing a plan on someone else's money

The arrangement simplifies the funding and complicates the choosing. Chasing the cheapest premium when an allowance is on the table is a classic error — a lower premium usually means a higher deductible and a narrower network, and the difference comes out of your pocket, not the employer's. The working rules: know your exact allowance before comparing; start with silver-tier plans if you are under an ICHRA; open each plan's provider directory and search for your doctors by name; and price the annual cost-sharing, not just the monthly premium.

Common employer compliance mistakes

• Differentiating outside the eleven permitted classes, or unevenly within a class
• Skipping the affordability test — which wrongly strips employees of subsidy eligibility and exposes the employer to penalties
• Failing to offer the annual opt-out opportunity
• Reimbursing non-qualified coverage (for example, short-term plans) instead of ACA-compliant individual plans
• Lax monthly substantiation — reimbursing without proof of coverage is an incorrect tax outcome
