Does ICHRA Really Have No Size Cap?

Individual Coverage Health Reimbursement Arrangements (ICHRA) are often touted for their flexibility and the claim that they have “no size cap,” meaning employers of any size can offer them. But is that the whole story? If you’re a micro-business or a small company trying to figure out your health insurance options, this blog post will untangle the important details about ICHRA size limits, off-exchange vs on-exchange purchases, and why understanding eligibility and tax credits is crucial.

Understanding the Basics

What is ICHRA?

ICHRA stands for Individual Coverage Health Reimbursement Arrangement. It’s an employer-funded health benefit that reimburses employees for individual health insurance premiums and, sometimes, out-of-pocket medical expenses.

Employer reimbursement: Employers give a fixed allowance to employees who purchase coverage on the individual market, whether directly from carriers or through marketplaces.
Individual plan: Employees buy their own insurance policies tailored to their needs rather than subscribing to a group plan purchased by the employer.

Defining the Size Cap Statement

The often repeated phrase “ICHRA has no size cap” means that unlike traditional small group health insurance plans, which are typically available to businesses with 1-50 employees (varies by state), ICHRA allows employers of any size — even large employers — to reimburse employees for individual plans.

However, this doesn’t mean there are no limitations or considerations. It’s important to state-by-state health insurance rates explore how eligibility, purchase routes, and tax credits play a role in whether ICHRA is the right choice.

Off-Exchange vs On-Exchange: Purchase Routes, Not Plan Quality

One confusing aspect when discussing ICHRA is the difference between off-exchange and on-exchange individual plans. But before diving in, let’s define these terms to avoid ambiguity.

On-exchange: Health plans purchased through a government-run health insurance marketplace like Healthcare.gov or state exchanges. These plans qualify for Advanced Premium Tax Credits (APTC), a subsidy to reduce monthly premiums.
Off-exchange: Health plans bought directly from insurance carriers’ websites or brokers/manufacturers without going through the marketplace. These do not qualify for premium tax credits.

One client recently told me made a mistake that cost them thousands.. Why does this matter for ICHRA? An ICHRA participant can buy either an on-exchange or off-exchange individual plan. Employers reimburse based on documentation of eligible expenses, so choice of purchase route doesn’t affect the quality or types of plans available. It only impacts whether employees can receive tax credits.

Mini-scenario: Choosing an ICHRA plan route

Maria’s employer offers an ICHRA stipend. She wants a Blue Cross individual plan but finds it cheaper on Healthcare.gov and qualifies for $200/month premium tax credits.
Because of ICHRA rules, Maria cannot claim premium tax credits when reimbursed, so she may choose to buy off-exchange to avoid canceling tax credits or calculate carefully.

This example highlights why understanding off-exchange vs on-exchange is a purchase route issue, not a plan quality issue.

Individual vs Small Group Eligibility: Who Qualifies?

Many employers mistake the owner-only status or small size as a block to offering traditional small group coverage. To clarify:

Small group plans: Usually available to employers with at least one common-law employee beyond the business owner(s). In some states, coverage can be limited to companies with up to 50 or fewer employees.
Owner-only businesses: Typically not eligible for small group market plans because there are no common-law employees.
ICHRA eligibility: Available regardless of the number of employees, including owner-only companies.

Here’s why this matters: If you’re an owner-only business, you probably can’t buy a small group plan directly but can offer ICHRA and reimburse yourself for an individual plan.

Mini-scenario: Owner-only business choice

Jason owns a consulting firm with no other employees. He cannot buy a traditional small group plan.
Jason sets up an ICHRA for himself, buying an individual policy and submitting premiums for reimbursement.
This is a legally compliant way for owner-only firms to get tax-deductible employer-funded health coverage.

SHOP Marketplace: Basics and Availability Limits

The Small Business Health Options Program (SHOP) Marketplace is a special ACA marketplace https://smoothdecorator.com/what-is-ichra-and-why-do-some-small-businesses-prefer-it/ for small employers (1-50 employees). Employers can purchase qualified small group plans through SHOP.

Availability limit: SHOP is generally for businesses with 1-50 employees (definitions and limits vary by state).
Tax credit integration: Employers buying through SHOP may qualify for Small Business Health Care Tax Credits, if eligibility rules are met.
Employee choice: Depending on the plan, the employer can decide the level of choice employees have within the SHOP plan offerings.

Unlike ICHRA, SHOP plans are group insurance products, not individual coverage.

Why might a small employer choose SHOP over ICHRA?

Access to group plan rates and simplified premium billing.
Ability to claim Small Business Health Care Tax Credits if the employer qualifies.
Less administrative burden on employees to shop individually.

Think about it: but shop limits mean an employer with 51+ employees cannot use shop, while ichra can be offered by any size employer.

Small Business Health Care Tax Credit: The Driving Force

The Small Business Health Care Tax Credit is a big deal in controlling whether employers pick traditional small group plans or ICHRA.

Eligibility rules include:

Employers must have fewer than 25 full-time equivalent employees.
Average employee salary must be under a certain threshold (about $56,000 in 2024).
Must pay at least 50% of employee-only premiums.
Must buy a health plan through SHOP Marketplace, not off-exchange or reimburse individual plans.

Why does this matter? Employers who want to qualify for this tax credit cannot use ICHRA because ICHRA reimbursements for individual plans do not count as premium payments for this credit. Therefore, the tax credit often pushes small employers with fewer than 25 employees toward SHOP Marketplace plans instead.

Mini-scenario: Tax credit impact on choice

Anne owns an 18-employee home-cleaning business and qualifies for the Small Business Health Care Tax Credit.
She buys coverage through the SHOP Marketplace to get the tax credit and lower her total cost.
If she switched to an ICHRA, she would lose the credit, potentially increasing net expenses.

Putting It All Together: When Does “No Size Cap” Matter?

Employer Size Small Group Eligibility SHOP Marketplace Available? Small Business Tax Credit Eligible? ICHRA Available? Recommended Path Owner-only (1 person) No (no common-law employees) Usually no No (needs employees) Yes Set up ICHRA and reimburse individual plans 1–25 employees Yes (small group market) Yes Potentially yes Yes Tax credit eligible: choose SHOP Marketplace plans Not eligible: ICHRA may be viable 26–50 employees Yes Yes No (too many employees or salary) Yes ICHRA or SHOP plans depending on price and administrative preference 51+ employees Yes (large group market) No (SHOP doesn't apply) No Yes Typically large group plans or ICHRA if desired

Final Thoughts

ICHRA truly has no size cap — it can be offered by any employer size, including very large firms or owner-only businesses. But that does not mean it’s the automatic or best choice for every business.

Key takeaways:

Purchase route (off-exchange vs on-exchange) is a choice, not a quality indicator. ICHRA participants can choose plans off or on exchange, but tax credit availability affects employee costs.
Small group eligibility depends on having common-law employees and company size. Owner-only businesses can’t use small group plans but can use ICHRA.
SHOP Marketplace is useful for eligible small employers who want group coverage and tax credits. It has size and location limits.
Small Business Health Care Tax Credit rules often determine whether SHOP or ICHRA is financially better. Losing the credit by choosing ICHRA can mean higher net costs despite flexibility.

If you’re a micro-business or small employer navigating these choices, understanding the subtle but critical distinctions can save you thousands and prevent costly mistakes. Always consider your employee count, eligibility for tax credits, and whether employees want to shop plans on their own or through the employer.
