ICHRA for Small Business: How It Works, What It Costs, and 2027 Contribution Guidance

Quick answer: An ICHRA (Individual Coverage Health Reimbursement Arrangement) lets an employer of any size reimburse employees, tax-free, up to a monthly dollar amount the employer sets, for an individual health plan the employee chooses. There is no IRS contribution cap. To set one up you define employee classes, set an allowance for each class, adopt a written plan document, and send employees a notice at least 90 days before the plan year starts.

Group health premiums that jump at every renewal are pushing more small businesses to ask whether there’s a better way to offer health benefits. An Individual Coverage Health Reimbursement Arrangement (ICHRA) is that alternative: instead of picking one group plan for everyone, you set a fixed, tax-free monthly allowance and let each employee choose the individual plan that fits them. This guide walks through exactly how an ICHRA works, what it costs, how contribution amounts work heading into 2027, and how to set one up correctly.

What Is an ICHRA?

Individual Coverage HRA vs. traditional group health. With a traditional group health plan, you choose one plan (or a small menu of plans) from one carrier, and every employee enrolls in it. With an ICHRA, you don’t choose a plan at all — you set a dollar allowance, and each employee buys their own individual ACA-compliant plan on the marketplace or off-exchange, in whatever network and coverage level fits their situation. You then reimburse them, tax-free, up to the allowance you set.

Who can offer one. Any size business can offer an ICHRA — there’s no employee-count minimum or maximum, unlike some other HRA types. You can also offer an ICHRA to only part of your workforce (see employee classes below) while keeping a traditional group plan for the rest, which is one of the more common ways small businesses transition into ICHRA gradually rather than all at once.

How an ICHRA Actually Works, Step by Step

1. Employer sets a tax-free allowance by employee class. You decide how much to contribute per month, and you can vary that amount by employee class (see below) — for example, a higher allowance for full-time employees than part-time, or an age-adjusted amount within a class.
2. Employees buy their own ACA-compliant plan. Each employee shops the individual marketplace (or works with a licensed agent) to pick the plan that fits their doctors, prescriptions, and budget — something no single group plan can do for a whole team at once.
3. Employer reimburses premiums up to the allowance. Employees submit proof of their premium (and, if the ICHRA is structured to cover them, qualifying out-of-pocket medical expenses), and you reimburse up to the monthly allowance, tax-free to both sides.

Because the allowance is fixed and employer-set, your monthly benefits cost is predictable from the start of the plan year — the variable is which plan each employee picks, not what you owe.

ICHRA Contribution Limits and Classes for 2027

Here’s the detail that trips up a lot of employers researching this: unlike a QSEHRA, an ICHRA has no IRS-imposed statutory maximum on the allowance amount. You can set it as low or as high as your budget allows — there is no annually-adjusted dollar cap to look up for 2027, and there won’t be one published, because none exists for this HRA type. What you’re actually managing for 2027 isn’t a contribution ceiling; it’s setting an allowance that’s defensible, consistent, and — if you’re using the ICHRA to satisfy the ACA employer mandate — affordable under that year’s IRS affordability test.

How employee classes work. IRS rules let you vary the allowance across defined employee classes — common ones include full-time, part-time, salaried, hourly, seasonal, and geographic (by rating area). You must offer the same allowance to everyone within a class, and the class structure has to be based on legitimate, defined criteria rather than criteria chosen to single out specific individuals. If you keep a traditional group plan for one class and offer an ICHRA to another, minimum class size rules also apply: at least 10 employees in the class for employers with fewer than 100 employees, 10 percent for employers with 100 to 200 employees, and 20 employees for employers with more than 200.

Setting a defensible, non-discriminatory allowance. Within a class, everyone gets the same base allowance (an age-based variation is allowed, with the allowance for the oldest employee in a class capped at three times the allowance for the youngest). The goal is consistency you can explain and document, not a number picked ad hoc per employee.

The one 2027 figure that does matter: affordability. If you’re an Applicable Large Employer using an ICHRA to satisfy the ACA employer mandate, the allowance needs to clear that year’s IRS affordability threshold against the employee’s lowest-cost individual silver plan. For 2027, that affordability percentage rises to 10.22% of household income (up from 9.96% in 2026). In practice, that means the required allowance to stay “affordable” moves a little each year along with that percentage and local silver-plan pricing — worth re-checking annually rather than assuming last year’s allowance still clears the bar.

ICHRA vs. QSEHRA vs. Traditional Group Health

QSEHRA (Qualified Small Employer HRA) is the other tax-free reimbursement arrangement small employers ask about, and the two are easy to confuse. A QSEHRA is capped — for 2026, the IRS maximum is $6,450 for self-only coverage and $13,100 for family coverage annually (the IRS announces new limits each year, and we had not seen the 2027 figures when this article was last updated in October 2026) — and it’s only available to businesses with fewer than 50 employees that don’t offer any group health plan at all. An ICHRA has no size limit, no dollar cap, and can be offered to some employee classes while a traditional group plan continues for others.

Traditional group health insurance keeps one negotiated plan (or narrow menu) for the whole team, with the employer absorbing whatever the renewal increase turns out to be each year — you can compare current group health carrier plans to see what that looks like today. An ICHRA flips that: the employer’s cost is fixed by the allowance they set, and plan selection — and the risk of year-to-year premium swings on that specific plan — shifts to the employee choosing their own coverage.

In short: QSEHRA fits a small team that offers no group plan and wants a simple, capped benefit. Group health fits a business that wants one plan and predictable-if-rising renewals. An ICHRA fits a business — of any size — that wants a fixed budget line and is comfortable letting employees choose their own coverage. If you’re still weighing ICHRA against a traditional group plan for your specific situation, our ICHRA vs. Group Health Insurance comparison walks through the trade-offs in more depth.

A third path sits between the two: a level funded health plan keeps a group plan structure but funds claims with a fixed monthly payment and stop-loss protection. It is worth comparing if your group is healthy and you want to stay in a group plan.

What an ICHRA Costs a Small Business

Predictable budgeting vs. renewal-driven group premium increases. With group health, your cost each year is whatever the carrier’s renewal comes back at — and renewal increases well above general inflation are common, especially for smaller groups with less negotiating leverage. With an ICHRA, your total benefits line is the allowance you set times your headcount, full stop. You can still choose to raise that allowance year over year, but the decision to increase spending is yours to make deliberately, not a number a carrier hands you after the fact.

There’s no separate “ICHRA premium” the business pays beyond the allowance itself — administrative costs are typically limited to plan document setup and any ongoing administration platform or broker fee, which is generally modest relative to the premium savings many small employers see moving off a struggling group renewal.

How to Set Up an ICHRA: 7-Step Checklist

1. Decide who is eligible. Choose which employee classes will be offered the ICHRA, such as full-time, part-time, salaried, hourly, seasonal or by rating area. If you keep a group plan for one class and offer an ICHRA to another, minimum class size rules apply.
2. Set the monthly allowance for each class. Everyone in a class gets the same base amount, with optional age-based variation. If the ACA employer mandate applies to you, check the affordability math (10.22% of household income for 2027).
3. Choose a plan year and effective date. Build your timeline backward from this date, because the employee notice has to go out first.
4. Adopt a written plan document. It defines your classes, allowance amounts and reimbursement rules, and it is what makes the arrangement compliant.
5. Send the required notice. Federal rules require written notice at least 90 calendar days before the start of each plan year. Employees who become eligible later get it by the date the ICHRA first takes effect for them.
6. Help employees enroll. Employees pick an individual plan on or off the Marketplace, and those newly offered an ICHRA generally qualify for a Special Enrollment Period. Each employee can opt out of the ICHRA once per plan year.
7. Reimburse and document. Employees must show proof that they have individual coverage, and you confirm continued enrollment before each reimbursement. A simple monthly process keeps this manageable.

Timing note for a January 1, 2027 start: 90 calendar days before January 1, 2027 was October 3, 2026, so an employer adopting an ICHRA now will usually need a later plan year start date. A licensed broker or benefits attorney can confirm the right timeline for your situation.

Common ICHRA Mistakes Small Businesses Make

• Setting the allowance without checking the affordability math. If ACA employer-mandate compliance matters for your business, an allowance that looked fine last year can fall short once that year’s affordability percentage and local premiums shift.
• Defining employee classes loosely. Classes need to be based on legitimate, IRS-recognized criteria — informal groupings invite compliance problems if ever reviewed.
• Skipping the 90-day notice window. Waiting until close to the effective date to send required employee notices is one of the most common — and most avoidable — compliance missteps in a first-year ICHRA rollout.
• Assuming employees will navigate the marketplace alone. Employees who’ve never shopped for individual coverage often need real guidance comparing plans — without it, adoption and satisfaction both suffer, even when the allowance itself is generous.

Is an ICHRA a Good Idea for a Small Business?

It depends on what you want from your benefits. An ICHRA tends to fit when:

• You want a fixed, predictable benefits budget instead of a renewal number set by a carrier.
• Your team is spread across different states or rating areas, or has very different coverage needs.
• Group renewals have become hard to afford, or your group is too small to get good rates.

It may be a weaker fit when:

• You want every employee on one plan with one carrier and minimal decisions for staff.
• Your employees will need help shopping for individual coverage and you will not provide it.
• An allowance that is both affordable and attractive would cost far more than your current group contribution.

For most small businesses the right answer comes from running your actual numbers side by side: your current group renewal against a defensible allowance for each employee class.
