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 has had its own employer mandate since 1974, and some other states have specific requirements), but federally, small businesses are not required to offer coverage.

The FTE calculation

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

• Full-time = anyone working 30+ hours/week (counts as 1 FTE each)
• Part-time = combined monthly hours divided by 120 (rounded down)
• Seasonal workers (under 120 days/year) excluded

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 FTEs. Under 50, so the mandate doesn’t apply.

3. Traditional small-group health insurance

The default option most small businesses use. The employer purchases a group health plan from a carrier (BCBS, UnitedHealthcare, Cigna, etc.), and employees enroll through the plan. Employer typically pays 50–100% of the premium for the employee, less for dependents.

How it works

• Employer contracts with one or more carriers for group plans
• Employees enroll through open enrollment (typically annual) or new-hire SEPs
• Employer pays a portion of premium directly to carrier; employee share comes out of payroll pre-tax
• Plan is regulated as “small group market” (different rules than individual ACA)

Eligibility rules

• Minimum employee participation: Most carriers require 70–75% of eligible employees to enroll (waivers count for those with other coverage)
• Minimum employer contribution: Usually 50% of employee-only premium
• Defined eligibility: “Eligible” = 30+ hours/week W-2 employees

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
• Premiums are 100% tax-deductible for the business
• Employee share is pre-tax via Section 125 plan (Cafeteria Plan)

Disadvantages

• Employer has limited control over costs — renewals can spike if one employee has a high-claim year (community-rated in some states helps, age-rated in others doesn’t)
• Less flexibility for employees with widely different coverage needs
• Open enrollment management overhead
• Employees can’t take subsidies if they decline employer coverage (assuming it’s “affordable” at under 8.39% of household income)

4. ICHRA — the new flexible reimbursement option

An Individual Coverage Health Reimbursement Arrangement (ICHRA) lets the employer reimburse employees for health insurance premiums they buy themselves on the individual market (ACA Marketplace). Created by 2020 regulations, ICHRAs have grown rapidly because they offer flexibility employers want and predictability employees value.

How it works

1. Employer sets a monthly reimbursement amount (can vary by employee class — full-time vs part-time, by age, by family size)
2. Employee buys their own ACA-compliant health plan on Healthcare.gov
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

• Employees lose ACA subsidies if your ICHRA is considered “affordable” (under 8.39% of household income for self-only coverage). Most ICHRAs are affordable, which trades subsidy access for employer reimbursement.
• Administrative overhead — need an ICHRA platform like Take Command, HealthSherpa, or Gravie to handle reimbursements and compliance
• 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 businesses with under 50 employees that don’t offer a traditional group plan. Created by the 21st Century Cures Act of 2016.

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: $6,350 self-only / $12,800 family (2026 limits)
• Must be offered on the same terms to all eligible full-time employees
• Employees must have minimum essential coverage to receive reimbursements

Who can use QSEHRA

• Must have under 50 full-time-equivalent employees
• Must not offer a traditional group health plan (QSEHRA replaces it; can’t coexist)

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 actual claims come in lower than expected, the employer gets a refund at year-end.

How it works

1. Carrier estimates the group’s expected annual claims based on demographics and (sometimes) medical underwriting
2. Monthly “level” payment includes claims expectation + admin + stop-loss premium
3. Stop-loss kicks in if any individual claim exceeds a threshold (e.g., $50K) or if total group claims exceed the expected amount
4. End of plan year: if actual claims were lower than expected, employer receives a partial refund

Advantages

• Lower total cost for healthier groups (often 15–25% cheaper than fully-insured group)
• Refunds possible if claims experience is favorable
• Predictable monthly payment (the “level” part)
• Plan design flexibility — not subject to all state-mandated benefits requirements (ERISA preemption)

Disadvantages

• Medical underwriting — carrier reviews employee health to set rates; some unhealthy groups will be priced out or declined
• Year-end adjustments possible if claims exceed expectations
• More complex administration than fully insured
• Best for groups of 10+ — below that, claims volatility makes the math unfavorable

7. SHOP Marketplace

The Small Business Health Options Program (SHOP) is the federal small-group marketplace for businesses with 1–50 employees (50–100 in some states). It’s been less popular than expected since launch, with most small businesses going through brokers and direct carriers instead. But SHOP has one unique advantage: tax credits.

SHOP Small Business Health Care Tax Credit

If you have under 25 FTE employees, average wages under $63,000 (2026), pay at least 50% of employee premiums, and buy coverage through SHOP, you may qualify for a tax credit of up to 50% of premiums paid for two consecutive years.

SHOP eligibility

• 1–50 employees (or 1–100 in CA, CO, NY, VT)
• Maintain a primary business location in the state where you’re buying coverage
• Offer SHOP coverage to all eligible full-time employees
• Have at least 70% employee participation (waivers count for other coverage)

Why it’s underused

Most small business brokers can sell the same carriers SHOP offers, with broader plan options and personalized service. SHOP’s main draw is the tax credit, but that requires you to have a very small, lower-wage workforce. For most small businesses with skilled higher-paid employees, off-SHOP brokerage is more attractive.

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. Owners often qualify for ACA subsidies personally, so personal Marketplace coverage with QSEHRA reimbursement is a common pattern.

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 increasingly competitive 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, with potential 15–25% savings vs fully-insured. Get quotes for both.

Over 50 FTEs

You’re now an Applicable Large Employer subject to the ACA’s employer mandate. Must offer coverage to 95% of full-time employees or face penalties. 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 1099 guide)
• 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); traditional group with community rating is better
