ICHRA vs Group Health Insurance: What Employers Really Need to Know

What is Individual Coverage HRA (ICHRA)?

The core difference between ICHRA vs group health insurance comes down to who's holding the risk. With a traditional group health plan, your company picks a carrier, picks a plan (or two or three), and absorbs whatever the renewal increase is every year. With an Individual Coverage HRA (ICHRA), you set a fixed dollar budget, your employees shop for their own individual market plan, and you reimburse them tax-free up to that budget. You're not buying a plan anymore. You're funding a benefit. That one shift changes almost everything else: your renewal math, your compliance paperwork, your HR workload, and honestly, how much choice your employees actually get. Neither approach is automatically better. It depends on your headcount, your workforce spread, and how much cost certainty you want. Let's get into the actual mechanics so you can make a real decision instead of a gut call.

What's Actually Different Between an ICHRA and a Group Health Plan?

A group health plan is a single contract (or a small handful of contracts) between your company and an insurance carrier. Everyone eligible gets the same plan design, more or less, and your company pays a big chunk of a premium that the carrier sets based on your group's claims history, size, and location. If your group has a bad claims year, your renewal reflects it. You're locked into whatever the carrier offers in your state and whatever network they've negotiated.

An ICHRA flips the funding model. Your company decides on a monthly dollar allowance per employee (you can vary it by employee class, which we'll cover below), and employees use that allowance to buy a plan on the individual market, either through Healthcare.gov, a state exchange, or off-exchange directly from a carrier. Employees own the policy. You're not underwriting anything, so your monthly cost doesn't move based on who gets sick this year. It moves only when you decide to change the allowance.

This is a real structural change, not just a different label on the same thing. Under a group plan, the insurance company is pricing risk. Under an ICHRA, you're pricing a budget. The final ICHRA rule came out of a joint effort by the Treasury Department, the Department of Labor, and the Department of Health and Human Services in 2019, and it's been usable by employers of any size since plan years starting on or after January 1, 2020.

How Do the Costs and Employee Experience Actually Compare?

Numbers matter here more than opinions. Here's how the two models stack up across the things employers actually care about:

●Cost predictability: Group plans expose you to annual renewal swings, sometimes double digits, that you don't control. An ICHRA lets you set your contribution and know your total spend for the year, since you're not exposed to claims experience.

●Plan choice for employees: Group plans typically give employees two or three options, all from one carrier. ICHRA opens up the entire individual market in that person's zip code, which in many areas means dozens of plans across multiple carriers and metal tiers.

●Administrative burden: Group plans require annual RFPs, renewal negotiations, and carrier relationship management. ICHRA administration shifts toward setting up classes, communicating allowances, and verifying reimbursement substantiation, which is a different kind of work, not necessarily less, but more predictable.

●Employee experience: Some employees love picking their own plan and keeping it if they change jobs, since individual policies aren't tied to your company. Others find shopping on the individual market confusing, especially if they've never done it before. Education matters a lot here, more than most employers expect going in.

Neither column is universally better. A company with a young, healthy, geographically spread-out workforce often does better on ICHRA. A company with an older workforce concentrated in one metro area with strong group rates might still come out ahead on a traditional plan.

Who Can You Actually Offer an ICHRA To?

Employee Classes

You don't have to offer the same ICHRA allowance to every employee, and you don't even have to offer ICHRA to everyone. The final rule lets you divide your workforce into permitted classes and set different contribution amounts for each one. The recognized classes include:

●Full-time employees

●Part-time employees

●Seasonal employees

●Employees in a waiting period

●Salaried employees

●Non-salaried (hourly) employees

●Temporary employees of a staffing firm

●Employees covered under a collective bargaining agreement

●Foreign employees who work abroad

●Employees in different geographic locations (based on rating area, state, or a combination)

You can also combine classes, like offering one allowance to full-time salaried employees and a different one to part-time hourly employees.

Minimum Class Size Rules

If you want to vary contributions within a class by age or family size, there's a floor on how many people have to be in that class first, so a company can't just carve out one person to dodge the rules. Per the Treasury/DOL/HHS final rule (Federal Register, 2019), the minimum class size is: 10 employees for employers with fewer than 100 total employees, 20 employees for employers with 100 to 200 total employees, and 10% of the total workforce for employers with more than 200 employees. This only applies when you're varying contributions by age or family status inside a single class, not when you're just offering different flat amounts across different classes.

Does Offering an ICHRA Satisfy the ACA Employer Mandate?

For employers with 50 or more full-time equivalent employees, this is usually the question that decides everything. Under Internal Revenue Code Section 4980H, applicable large employers have to offer coverage that's both minimum essential and affordable to full-time employees, or risk an Employer Shared Responsibility Payment (ESRP). An ICHRA can satisfy that requirement, but only if the contribution is structured to be affordable under IRS rules.

Affordability gets measured against the ACA affordability percentage, which the IRS updates every year through a Revenue Procedure. For 2025 plan years, that percentage is 9.02% of household income (IRS Revenue Procedure 2024-35). Since employers usually don't know an employee's household income, the IRS also allows a Federal Poverty Line (FPL) safe harbor, which for 2025 plan years works out to roughly $113.20 per month for self-only coverage, based on HHS Poverty Guidelines applied through IRS guidance. If your ICHRA contribution, after subtracting the lowest-cost silver plan premium available to that employee, leaves them paying less than that monthly amount, you're covered under the safe harbor. These figures move every year, so always confirm the current number on IRS.gov before finalizing a contribution strategy for the upcoming plan year.

Get it wrong, and the penalties aren't small. The IRS publishes updated ESRP amounts annually on its Affordable Care Act Employer Shared Responsibility Provisions page. For 2025, the 4980H(a) penalty (for not offering coverage at all) runs about $2,900 per full-time employee annually (minus the first 30 employees), and the 4980H(b) penalty (for offering coverage that isn't affordable or doesn't meet minimum value) runs about $4,350 per affected employee annually. This is exactly why affordability math needs to happen before you set allowances, not after.

How Do You Actually Switch From a Group Plan to an ICHRA?

Moving off a group plan isn't something you flip on overnight. There's a real sequence to it, and skipping steps is how employers end up with confused employees and compliance gaps. Here's the practical order of operations:

1.Decide your effective date and give notice early. The final rule requires a written notice to eligible employees at least 90 days before the start of the plan year in most cases, so this isn't a last-minute email.

2.Set your classes and allowances. Decide which employee classes you're offering ICHRA to and what monthly amount each class gets, keeping the affordability safe harbor in mind if you're an applicable large employer.

3.Run the affordability math for every class. Check contribution amounts against the lowest-cost silver plan in each relevant rating area, not just your headquarters city.

4.Draft or update your ERISA plan document and summary plan description. ICHRA is a group health plan for ERISA purposes, so it needs the same documentation as any other employer health benefit.

5.Coordinate your group plan termination date. Employees need continuous coverage, so the timing between when the group plan ends and the ICHRA (and their new individual policy) starts has to line up cleanly, usually tied to the individual market's open enrollment or a special enrollment period triggered by the loss of group coverage.

6.Educate employees on how to actually shop for a plan. This is the step employers underestimate most. Many employees have never bought individual coverage before, and a confusing rollout undoes a lot of the goodwill you're trying to build.

7.Set up reimbursement and substantiation processes. Employees need to submit proof of individual coverage and eligible expenses before reimbursements go out, so you'll want this running before the first paycheck cycle under the new benefit.

If you want a partner to handle the plan document work, class setup, and reimbursement administration instead of building it in-house, that's exactly what CafeHealth's ICHRA administration service is built to do.

What Compliance Work Does an ICHRA Actually Require Once It's Running?

An ICHRA isn't a set-it-and-forget-it benefit. It's an ERISA-covered group health plan, which means it comes with ongoing obligations similar to a traditional plan, just structured differently:

●ERISA plan documents: You need a written plan document and a summary plan description, and both need updating any time you change classes or allowances.

●Substantiation of reimbursements: Before reimbursing any employee, you (or your administrator) have to verify they're enrolled in individual health insurance that qualifies as minimum essential coverage. This has to happen for every reimbursement cycle, not just once at enrollment.

●Annual notice requirements: The 90-day advance notice isn't a one-time thing. It applies every plan year you're running an ICHRA, including years where nothing about the design changes.

●Affordability recalculation: Because the IRS affordability percentage and FPL safe harbor amounts change annually, applicable large employers need to re-check their contribution amounts every year to stay inside the safe harbor.

●Form 5500 filing: Depending on plan size and structure, your ICHRA may need to be included in your Form 5500 filing, same as other ERISA welfare benefit plans.

None of this is harder than group plan compliance, but it's different, and it's easy to assume it's simpler than it actually is because there's no carrier relationship to manage. The paperwork just moves to a different part of the process.

So Which One Actually Makes Sense for Your Company?

If your workforce is spread across multiple states or rating areas, ICHRA usually wins on flexibility, since group plans often struggle to offer consistent coverBook a free chat with Shannon.
