Small Business Health Insurance: 5 Options Compared

1. Do small businesses legally have to offer health insurance?

For most small businesses, no. The ACA’s employer mandate — called the “Employer Shared Responsibility” or “Pay or Play” rule — only applies to businesses with 50 or more full-time-equivalent (FTE) employees. These are called Applicable Large Employers (ALEs).

If you’re under 50 FTEs, you have zero federal mandate to offer health insurance. You can hire and pay employees with no benefits at all and face no penalty. State rules can differ: Hawaii’s Prepaid Health Care Act, first enacted in 1974, generally requires employers to provide coverage to employees who work at least 20 hours a week and meet a monthly earnings test. But federally, small businesses are not required to offer coverage. For a fuller rundown of the federal and state rules, see our small business health insurance requirements guide.

The FTE calculation

“Full-Time Equivalent” combines full-time and part-time hours:

• Full-time = an employee averaging at least 30 hours of service a week, or 130 hours a month (counts as 1 each)
• Part-time = add up the month’s hours for all non-full-time employees (no more than 120 per person) and divide by 120
• Seasonal exception: if you top 50 only for 120 days or fewer in a year, and the extra workers during that stretch are seasonal, you aren’t an ALE

Example: A business with 30 full-timers + 20 employees each averaging 15 hours/week = 30 + (20 × 15 × 4.33 / 120) = 30 + 10.8 = 40.8 for the month. If that holds all year, your annual average is 40.8, which the IRS rounds down to 40. Under 50, so the mandate doesn’t apply. (Whether you’re an ALE for a year depends on your average across the prior calendar year.)

2. Your 5 small business health insurance options at a glance

For a national benchmark, the KFF 2026 Employer Health Benefits Survey found an average annual premium of $9,593 for single coverage (about $799 a month) and $27,288 for family coverage at firms with 10–199 workers; workers at those firms paid 16% of the single premium and 37% of the family premium on average. For per-employee budget math by team size, see our small business health insurance cost guide.

3. Traditional small-group health insurance

The default option most small businesses use. The employer buys a group health plan from an insurance carrier licensed in your state, and employees enroll through the plan. The employer typically pays at least about 50% of the employee-only premium (many pay more) and often less toward dependents. For a deeper walkthrough, see our small business group health insurance guide.

How it works

• Employer contracts with one or more carriers for group plans
• Employees enroll when they first become eligible, at the plan’s annual open enrollment, or after a qualifying event such as marriage, a birth or losing other coverage
• Employer pays a portion of premium directly to carrier; employee share usually comes out of payroll pre-tax through a Section 125 plan
• Fully insured plans follow ACA small-group rules: they cover the essential health benefits, and premiums can vary only by age, tobacco use, family size and rating area, not by your employees’ health (45 CFR 147.102)

Eligibility rules

• Minimum employee participation: Carriers typically require about 50–75% of eligible employees to enroll; employees who waive because they have other coverage often aren’t counted against you (SHOP generally requires 70%)
• Minimum employer contribution: Commonly about 50% of the employee-only premium
• Defined eligibility: “Eligible” usually means W-2 employees working 30+ hours a week; you set the rule within carrier limits

Advantages

• Employees value it — tangible benefit on a paystub
• Simpler from employee perspective — one plan, automatic deductions
• Group rates can be better than individual market in some areas
• Employer premium contributions are generally tax-deductible business expenses (confirm with your CPA)
• Employees can usually pay their share pre-tax through a Section 125 (cafeteria) plan

Disadvantages

• Limited control over costs — because fully insured small-group premiums can’t reflect your employees’ health, a good claims year won’t lower your renewal; the carrier’s rate changes and your team’s ages drive it
• Less flexibility for employees with widely different coverage needs
• Open enrollment management overhead
• Employees offered affordable coverage that meets minimum value can’t get a Marketplace premium tax credit instead, even if they decline it. “Affordable” means the employee’s share for self-only coverage is no more than 9.96% of household income in 2026, or 10.22% in 2027

4. ICHRA — the new flexible reimbursement option

An Individual Coverage Health Reimbursement Arrangement (ICHRA) lets the employer reimburse employees, tax-free, for individual health insurance they buy themselves, on or off the ACA Marketplace. Created by 2019 regulations that apply to plan years starting in 2020 or later, ICHRAs are open to employers of any size. On September 3, 2026, the SBA and CMS began calling them “CHOICE Arrangements”; the name changed, but the core rules did not. Full rules and 2027 affordability math: our ICHRA guide for employers. Head-to-head: ICHRA vs group health insurance.

How it works

1. Employer sets a monthly reimbursement amount for each employee class (for example, full-time vs part-time); within a class, the amount must be offered on the same terms and can rise only with age or number of dependents
2. Each employee buys individual health insurance (on or off the Marketplace) or Medicare; short-term plans and dental- or vision-only coverage don’t qualify
3. Employee submits proof of coverage to employer (or via ICHRA admin platform)
4. Employer reimburses employee tax-free up to the set amount
5. If the plan costs less than the reimbursement, employee can use remainder for other qualified medical expenses (depending on plan structure)

Advantages

• Cost certainty: Employer’s cost is fixed at the reimbursement amount — no premium spikes from claim experience
• Employee choice: Each employee picks the plan that fits their family, doctors, and budget
• Portability: Employee keeps the plan if they leave (just lose the reimbursement)
• No minimum participation requirements: Unlike traditional group plans
• Can vary by employee class — you can offer different amounts to full-time vs part-time, salaried vs hourly

Disadvantages

• Premium tax credit trade-off: an employee covered by the ICHRA can’t also get a Marketplace premium tax credit. An employee who opts out can claim the credit only if the ICHRA is unaffordable: take the lowest-cost silver plan’s self-only premium, subtract the monthly ICHRA amount, and compare what’s left with 9.96% of monthly household income in 2026 (10.22% in 2027).
• Administrative overhead — most employers use an ICHRA administrator to verify coverage, process reimbursements and send employees the required written notice (the federal model notice assumes delivery at least 90 days before the plan year)
• Employees do their own enrollment — more work for them than traditional group

5. QSEHRA — for very small businesses

The Qualified Small Employer HRA (QSEHRA) is the older cousin of ICHRA, designed specifically for employers with fewer than 50 full-time employees (including FTEs) that offer no group health plan at all. It was created by the 21st Century Cures Act, enacted in December 2016. More detail: What is a QSEHRA?

How it works

• Same reimbursement concept as ICHRA — employer reimburses employees for individual health insurance premiums and qualified medical expenses
• Reimbursement amounts are capped by IRS: $6,450 self-only / $13,100 family (2026 limits; the IRS had not published the 2027 limits as of early October 2026)
• Must be provided on the same terms to all eligible employees; you may exclude employees with under 90 days of service, those under age 25, part-time or seasonal workers, union-covered employees and nonresident aliens with no U.S. earned income
• Employees must have minimum essential coverage to receive reimbursements
• Employees must get a written notice at least 90 days before the year begins; the penalty for missing it is $50 per employee, up to $2,500 a year

Who can use QSEHRA

• Must not be an applicable large employer (generally, fewer than 50 full-time employees, including FTEs, in the prior year)
• Must not offer any group health plan to any employee, including another HRA, a health FSA, or employer-offered dental or vision coverage
• Covers employees only: non-employee owners (such as sole proprietors and partners) and more-than-2% S corporation shareholders can’t be reimbursed through it

QSEHRA vs ICHRA

QSEHRA is best for

Very small businesses (under 25 employees especially) where the reimbursement caps are sufficient, and where you want to avoid traditional group plan complexity. If reimbursement caps feel tight or you want different reimbursement levels by class, ICHRA is more flexible.

6. Level-funded plans

Level-funded plans blend self-insurance with the predictable payment structure of fully insured group plans. The employer technically self-insures employee claims, but pays a fixed monthly amount that covers (a) expected claims, (b) administrative costs, and (c) stop-loss insurance that caps the employer’s risk. If claims come in lower than expected, the plan may return a surplus at year-end, but surplus terms vary by carrier: some apply it as a credit toward renewal, and some pay nothing if you don’t renew. Deeper dive: how level-funded health plans work.

How it works

1. Carrier estimates the group’s expected annual claims based on your employee census and, typically, medical underwriting
2. Monthly “level” payment includes claims expectation + admin + stop-loss premium
3. Stop-loss insurance pays when one person’s claims pass a set threshold, or when the group’s total claims pass an aggregate limit
4. End of plan year: if claims were lower than expected, the employer may get a surplus refund or renewal credit, depending on the carrier’s terms

Advantages

• Can cost less than a fully insured plan for younger, healthier groups; we price both side by side
• Surplus refunds possible in a low-claims year, on the carrier’s terms
• Predictable monthly payment (the “level” part)
• Plan design flexibility — as self-funded plans, they aren’t required to cover the full ACA essential health benefits package and may be exempt from many state insurance rules

Disadvantages

• Medical underwriting — carrier reviews employee health to set rates; groups with higher expected claims may be priced higher or declined
• Renewals reflect your group’s own claims, so one expensive year can raise next year’s rate
• More complex administration than fully insured
• Eligibility varies — minimum group size and eligibility depend on the carrier and state

7. SHOP Marketplace (Small Business Health Options Program)

The Small Business Health Options Program (SHOP) is the ACA’s small-group marketplace for employers with 1–50 full-time-equivalent employees (some states open it to businesses with up to 100). In HealthCare.gov states, you enroll in SHOP plans through an insurance company or with the help of a SHOP-registered agent or broker. SHOP has one unique advantage: it’s generally the only way to claim the small business health care tax credit.

SHOP Small Business Health Care Tax Credit

If you have fewer than 25 FTE employees, pay average annual wages below the IRS limit, pay a uniform share of at least 50% of employee-only premiums, and buy coverage through SHOP, you may qualify for a tax credit of up to 50% of premiums paid (35% for tax-exempt employers) for two consecutive tax years. The credit is largest for employers with 10 or fewer FTEs and lower wages. For 2026, it starts shrinking once average annual wages pass $34,100 per FTE and phases out completely at about $68,200 (twice that amount, under the tax code’s formula). The IRS had not published the 2027 wage figure as of early October 2026.

SHOP eligibility

• 1–50 full-time-equivalent employees (some states allow up to 100)
• At least 1 FTE employee other than owners, owners’ spouses and family members, and partners
• An office or employee work site in the state whose SHOP you want to use
• Offer coverage to all full-time employees (generally those working 30+ hours a week)
• Generally, at least 70% of the employees you offer coverage to must enroll or have other coverage (some states set a different rate, and the rule doesn’t apply to enrollments between November 15 and December 15)

When SHOP is worth it

Apart from the tax credit, SHOP plans work much like other small-group plans. The credit requires a very small, lower-wage workforce, so most small businesses with higher-paid employees compare SHOP and non-SHOP small-group quotes on price and network.

8. Which option fits which business?

1–5 employees (micro business)

Best fit: QSEHRA or ICHRA

Traditional group plans require minimum participation that’s hard to hit at this size. Reimbursement models give you cost certainty and let your employees pick what works for them. One catch: a QSEHRA can only reimburse employees, and SHOP requires at least one employee who isn’t an owner, an owner’s spouse or family member, or a partner. Owners usually handle their own coverage separately; see our guide to health insurance for small business owners or our self-employed health insurance guide.

6–25 employees

Best fit: Traditional small-group OR ICHRA, depending on growth trajectory

Traditional group works at this size and is what employees expect. ICHRA is a strong alternative because of cost certainty — especially if you have employees in multiple states or want to avoid the participation minimums.

26–50 employees

Best fit: Traditional small-group OR level-funded for healthier groups

You’re approaching the ALE threshold (50 FTEs). Level-funded plans become attractive if your group skews younger/healthier, and they can come in below fully insured quotes. Get quotes for both.

50 or more FTEs

You’re now an Applicable Large Employer subject to the ACA’s employer mandate. To avoid a possible employer shared responsibility payment, you generally need to offer affordable, minimum-value coverage to at least 95% of full-time employees and their dependents. Traditional group plans are most common at this size. Level-funded and self-funded become viable. See your benefits broker for specific compliance requirements.

Special cases

• Distributed/remote team in multiple states: ICHRA usually wins — avoids juggling state-specific group plans
• Mix of W-2 and 1099: ICHRA can include W-2; 1099 contractors handle their own (see our guide to health insurance for 1099 contractors)
• Very low average wages, under 25 employees: SHOP for the tax credit may be worth it
• Industry with high health risk: Avoid level-funded (medical underwriting); fully insured small-group plans can’t price by health (adjusted community rating), so they’re usually the safer choice

Other routes: PEOs and association health plans

• PEO (professional employer organization): PEOs pool many small employers into one larger plan, which may give access to large-group-style pricing and plan options. Eligibility, underwriting and state rules vary. PEO providers and industry sources also note that plan choice is limited to the PEO’s menu and that admin fees come on top of premiums. See our PEO health insurance guide.
• Association health plans (AHPs): As of fall 2026, the pre-2018 Labor Department guidance governs AHPs. The department has sent a new proposed AHP rule to the White House for review, but it has not been published or finalized. Whether an AHP is available, and how it is regulated, depends on your state. See our association health plans guide.
