How to Set Up an ICHRA Plan: A Step-by-Step Timeline

Setting up an ICHRA is genuinely straightforward, but it is a benefit governed by federal rules, so a handful of compliance steps have to happen in the right order — and one of them has a hard 90-day deadline. This is the complete timeline, from the decisions you make before you start to your team's first tax-free reimbursement.

Before you begin: four decisions

Nail these down first, because everything else builds on them:

Budget — how much you will contribute per employee, per month.
Employee classes — one flat allowance for everyone, or different amounts by class.
Eligible expenses — premiums only, or premiums plus qualified medical expenses.
Plan year — the start date, which sets your 90-day notice deadline.

Step 1 — Choose an ICHRA administrator

You can technically self-administer, but a dedicated administrator saves time and keeps you compliant. They handle plan-document creation, employee notices, reimbursement processing, and compliance tracking — the pieces most likely to go wrong if you improvise.

Step 2 — Design the plan

Define your employee classes

The IRS permits distinct classes — full-time, part-time, seasonal, geographic rating area, salaried vs. hourly, and more — each of which can carry its own allowance. This is what lets the plan fit your actual org chart instead of forcing one number on everyone.

Set allowance amounts

Common structures:

A flat rate for all employees (for example, $500/month).
Tiered amounts by employee class.
Amounts that vary by family status — employee-only vs. family.

Step 3 — Create the plan documents

Every ICHRA needs a formal written plan document covering:

Eligible-employee definitions
Allowance amounts per class
Eligible expenses
Plan-year dates
Claims procedures
HIPAA privacy notices

Step 4 — Provide the 90-day employee notice

This is the deadline that catches employers off guard. You must give written notice to every eligible employee at least 90 days before the plan year begins. The notice has to spell out:

Their ICHRA allowance amount
That they need individual coverage to participate
Their right to opt out
How opting in or out affects ACA premium tax credit eligibility

Back-plan from your start date

For a January 1 plan year, the notice must be in employees' hands by roughly early October. Miss that window and you generally cannot launch on time — so if you are targeting a new-year start, plan design and documents should be done by late summer. Build in buffer; the 90 days is a floor, not a target.

Step 5 — Employee enrollment

Help employees understand their options and enroll in qualifying individual coverage. Point them to the ACA marketplace and off-exchange plans, and be ready for questions about networks and the subsidy trade-off. Our what is ICHRA page is a useful primer to share with staff.

Step 6 — Launch and administer

Once the plan year starts, the ongoing rhythm is simple:

Collect proof of individual coverage from each participant.
Process monthly reimbursements up to each allowance.
Track allowance usage.
Maintain compliance records.

Common setup mistakes to avoid

Missing the 90-day notice deadline.
Skipping or shortcutting the formal plan documents.
Offering an ICHRA and a group plan to the same employee class.
Failing to verify each participant's individual coverage.
Misclassifying employees across classes.

How the affordability test fits into setup

If you are an applicable large employer (50+ full-time-equivalent employees), your plan design has one extra constraint worth building in from the start. The ICHRA must be "affordable," meaning an employee's remaining cost for the lowest-cost silver plan in their area — after your allowance — cannot exceed 9.02% of household income (the 2026 threshold). In practice, that means your allowance amount is not just a budget decision; it is also a compliance lever. Setting it a little higher in high-premium counties can move an offer from "unaffordable" to "affordable," which affects both your ACA obligations and each employee's subsidy math. Your administrator will run this test by rating area as part of plan design so there are no surprises after launch.

Frequently asked questions

How long does it take to set up an ICHRA?

The active work is usually one to two weeks once you have decided on budget, classes, and plan year. The real constraint is the calendar: the required employee notice must go out at least 90 days before the plan year starts.

What happens if I miss the 90-day notice deadline?

You generally cannot launch on your target plan-year date. The 90-day notice is a firm requirement, so if you miss it you will typically need to push your start date. Plan design and documents should be finished with buffer to spare.

Do I need a formal plan document, or is an email enough?

You need a formal written plan document covering eligibility, allowances, eligible expenses, plan-year dates, claims procedures, and HIPAA privacy notices. An email announcement does not satisfy the requirement, which is one reason most employers work with an administrator.

The bottom line

Six steps, one hard deadline, and a set of documents that have to be right the first time — that is the whole ICHRA setup. Most small businesses complete it in one to two weeks of active work once decisions are made, with the calendar (not the effort) being the main constraint thanks to the 90-day notice.
