ICHRA compliance, in plain English

What ICHRA compliance actually means

ICHRA compliance is not a single filing or certification — it is a short list of obligations that together keep reimbursements tax-free: a plan document that establishes the arrangement, a written notice delivered on time, proof of coverage before any money moves, class rules applied evenly, and records that show all of it happened. This page maps each obligation; each has its own detailed guide. Miss one and the arrangement does not just get untidy — the tax treatment that makes an ICHRA worth running is what is at stake.

The plan document

Every ICHRA starts as a written plan. The plan document legally establishes the arrangement and fixes its terms: who is eligible, the allowance by class, the plan year, and how reimbursements run. Employers sometimes treat this as paperwork to backfill later; it is not — the document is what makes the arrangement real, and it should exist before the benefit is offered.

The employee notice

The ICHRA notice is the compliance step employers most often mistime. Existing employees generally must receive it at least 90 days before the plan year begins, and new hires before their coverage takes effect. The notice explains the allowance and — critically — how the offer interacts with ACA premium subsidies, which is why its timing matters as much as its content.

Substantiation before reimbursement

No reimbursement should move until the employee has substantiated qualifying individual coverage or Medicare — and employees re-attest annually. Substantiation is the rule that separates an ICHRA from cash: it proves the money paid for real coverage, and skipping it can turn tax-free reimbursements into taxable ones. The mechanics are covered in the ICHRA rules guide.

Class rules and same terms

Allowances may differ between employee classes and may scale by age and family size — but inside a class, everyone gets the same offer. Class design is where the flexibility lives, and also where employers most easily drift out of bounds: the permitted classes are a defined list, not a free-form grouping tool.

One class, one benefit

The rule that surprises employers moving off a group plan: the same class of employees cannot be offered both the group plan and the ICHRA. Different classes can get different benefits, subject to minimum class-size rules that exist to prevent steering high-cost employees onto the individual market. How that plays out in a transition is covered in ICHRA vs group insurance.

Affordability and subsidies

Whether an ICHRA counts as affordable is tested per employee, against a benchmark plan for their age and location and an IRS percentage that adjusts annually. Affordability decides whether an employee can take a marketplace subsidy instead, and for applicable large employers it decides whether the ICHRA satisfies the employer mandate. The full mechanics live in the affordability guide.

Reporting and recordkeeping

Keep the signed plan document, every notice, and the substantiation behind each reimbursement. Applicable large employers also report the ICHRA offer on Form 1095-C, since it counts as an offer of coverage. Records are the boring half of compliance and the half that protects you — if the tax-free treatment is ever questioned, the paper trail is the answer.

Do you need compliance software?

Searches for ICHRA compliance software usually mean the recurring workload: attestations, notice delivery, reimbursement records. ICHRA software automates that work; administrators bundle it with support. A very small team with a broker can run compliant manually — but past a handful of employees, automation is usually cheaper than the time it replaces. Deciding between the two is a good conversation to have with a specialist.

The annual compliance rhythm

• Before each plan year: refresh the employee notice and deliver it on time — generally at least 90 days ahead for existing employees.
• At enrollment: collect coverage attestations for the new plan year.
• Every reimbursement: substantiate before paying.
• Ongoing: keep notices, attestations and reimbursement records where you can produce them.
• At renewal: re-check affordability against the updated IRS percentage before setting allowances.
