There are four realistic small business health insurance options, and choosing between them is less about price than about one question: how stable is your payroll?
A dental practice with six salaried staff can buy a group plan and forget about it. A bakery with four full-time packers, three drivers whose hours swing with the season, and two people who pick up Saturdays has a different problem. Group plans ask you to define who is eligible and then hold that definition steady. Variable hours do not hold steady.
This guide compares the structures rather than the carriers, and it is written around the eligibility question specifically. For what each route costs per employee, and for where health coverage sits in a wider benefits package, those have their own guides.
Key Takeaways
- Small group plans are generally available to employers with 1 to 50 full-time equivalents, bought through a broker, a carrier, or the SHOP marketplace (CMS).
- A QSEHRA is the usual alternative for employers under 50 FTEs with no group plan. For 2026 it reimburses up to $6,450 a year for self-only coverage and $13,100 for family.
- An ICHRA has no size limit and no contribution cap, which makes it the most budget-predictable option for a payroll that moves.
- The Small Business Health Care Tax Credit requires fewer than 25 FTEs, an average wage under roughly $50,000, and at least half of employee premiums paid, generally on a SHOP plan.
- Your full-time equivalent count is calculated from hours worked, not job titles, so a seasonal spike can change which options you qualify for.

The four small business health insurance options
| Option | Who it fits | Size limit | Cost behaviour |
|---|---|---|---|
| Small group plan | Stable headcount, mostly full-time | ~1–50 FTEs | Premiums renew, usually upward |
| QSEHRA | Under 50 FTEs, no group plan | Under 50 FTEs | Fixed, capped by law |
| ICHRA | Any size, variable payroll | None | Fixed, you set the amount |
| Level-funded plan | 15+ employees, stable, healthier group | Practical floor, not legal | Partly variable with claims |
Everything below is detail on those four rows, plus the eligibility mechanics that decide which rows you actually qualify for.
Small group health insurance: eligibility and what it commits you to
A small group plan is what most people picture. You buy coverage as the employer, pick how much of the premium you cover, and employees enrol during an annual window.
The eligibility rules that matter:
- Size. The small group market generally runs from 1 to 50 employees, and up to 100 in some states.
- Participation requirements. Carriers typically require a minimum share of eligible employees to enrol, often around 70%. This is the rule that catches small employers whose staff are covered by a spouse’s plan.
- Contribution requirements. Carriers usually require the employer to cover a minimum percentage of the employee-only premium, commonly 50%.
- Self-employed with no employees generally cannot buy in the small group market and shop the individual market instead.
Where to buy: through a broker, directly from a carrier, or through the SHOP marketplace. SHOP matters for one specific reason: claiming the Small Business Health Care Tax Credit generally requires a SHOP plan (CMS).
The commitment to understand before signing: a group plan locks you into a defined eligibility class for the plan year, and premiums renew. If your headcount or your hours mix changes materially mid-year, the plan does not flex with you.
QSEHRA: the usual alternative when a group plan is out of reach
A Qualified Small Employer Health Reimbursement Arrangement flips the model. Instead of buying a plan, you reimburse employees tax-free for coverage they buy themselves.
The mechanics:
- Eligibility. Fewer than 50 full-time equivalents, and you must not offer a group health plan.
- 2026 caps. Up to $6,450 a year for self-only coverage and $13,100 for family coverage. You choose any amount up to the cap.
- Tax treatment. Reimbursements are free of payroll tax to you and income tax to the employee, provided they have qualifying individual coverage.
- Classes. You can vary the amount only by family status and age, within limits, not arbitrarily by person.
Why this suits a route-based payroll: your cost is a number you set, not a premium a carrier sets. A December hiring spike raises your total spend proportionally and predictably, instead of triggering a plan amendment.
The honest downside is that employees must shop for their own coverage, and some will find that harder than enrolling in a plan you chose. Budget time to help, especially in the first year.
One practical note for employees who end up on a high-deductible plan: the deductible is only survivable if the cash exists when it is needed. Pairing the plan with an HSA, or simply holding the money in a high-yield savings account, is the difference between a plan that covers people and one they are afraid to use.
ICHRA: the same idea without the ceiling
An Individual Coverage HRA works like a QSEHRA with two constraints removed: there is no employer size limit and no cap on how much you can reimburse.
That makes it the strongest fit for the specific problem this page is about. You can define employee classes by full-time or part-time status, salaried or hourly basis, and location, then set a different contribution for each, which is a legitimate way to handle a workforce where a full-time packer and a Saturday driver are different arrangements in practice.
Two cautions. Class rules have specifics, including minimum class sizes in some configurations, so this is worth setting up with an administrator rather than improvising. And an ICHRA offer that is considered affordable blocks the employee from claiming a premium tax credit on the exchange, which can leave a low-wage employee worse off than they would have been with no offer at all. Run that comparison before you set the contribution.
Level-funded plans: the middle option
A level-funded plan sits between fully insured and self-funded. You pay a steady monthly amount covering expected claims, administration and stop-loss insurance, and if claims come in below expectations you may get money back.
It can work well, with conditions:
- You need enough employees for claims to average out, commonly 15 or more, though it varies by administrator.
- Your group needs to be relatively healthy, because the upside depends on claims running below projection.
- You need tolerance for variability. The cost is level within a year, but renewal reflects your own claims history rather than a community rate.
For a business whose headcount swings seasonally, level-funded is usually the wrong answer — the small, stable denominator that makes it work is the thing you do not have. Worth revisiting once your core team is steady above 15 or so.
Health insurance for part-time employees and variable hours
This is the mechanism that decides everything above, and it runs on hours rather than titles.
- Full-time equivalents are calculated from hours worked. Add up all hours by non-full-time employees in a month, divide by 120, add your full-time count. That figure determines whether you are under the 50-FTE line for QSEHRA eligibility and whether Affordable Care Act employer rules apply to you.
- Plan eligibility definitions set their own threshold, commonly 30 hours a week. If your own plan document says 30 and a driver averages 32 for a measurement period, they are eligible under your plan whether you intended it or not.
- Measurement periods are a choice you should make deliberately. Look-back measurement over a defined period gives you a stable answer for people whose weekly hours bounce. Deciding month to month gives you a different answer every month.
Three habits cover most of the risk:
- Track average hours monthly, from payroll data rather than the posted schedule.
- Write the eligibility definition and the measurement period into the plan document, including how seasonal hours are treated.
- Check your FTE count before adding seasonal headcount, not after.
The failure mode here is rarely a penalty. It is finding out during a renewal audit that someone became eligible months ago, and owing coverage or correction for a period you cannot go back and change.
The Small Business Health Care Tax Credit
If you are close to qualifying, this is worth structuring for, because it can offset a meaningful share of premiums.
The conditions:
- Fewer than 25 full-time equivalent employees.
- Average annual wages below roughly $50,000 per FTE.
- You pay at least 50% of employee-only premiums.
- Coverage generally purchased through SHOP.
The credit is larger the smaller and lower-paid your workforce, and it phases out as you approach the thresholds. Note the tension with everything above: the credit requires a group plan through SHOP, while a reimbursement arrangement is often the better operational fit for variable hours. Price both. For some small employers the credit is large enough to make the group plan the cheaper route despite the administrative friction.
How to choose between the small business health insurance options
Work through these in order:
1. Count your FTEs properly. From payroll hours, over the last twelve months, including seasonal peaks. This number determines which options are even available.
2. Decide whether your payroll is stable or variable. Stable and mostly full-time points to a group plan. Variable points to an HRA.
3. Check the tax credit. Under 25 FTEs with average wages under about $50,000 means run the SHOP numbers before deciding.
4. Test affordability from the employee’s side. Particularly with an ICHRA, confirm the contribution does not block a premium tax credit that would have left a low-wage employee better off.
5. Set the contribution you can sustain year-round, not the one you can afford in peak season.
A benefit that fits the budget is worth more than one that technically exists on paper. Health coverage is only one piece of the offer. Paid time off, a retirement plan and a wellness program built for physical work all compete for the same money, and health insurance should not consume so much of it that nothing else happens.
Frequently asked questions
What are the health insurance options for a small business?
Four: a small group plan bought through a broker, carrier or SHOP; a QSEHRA for employers under 50 FTEs with no group plan; an ICHRA, which has no size limit or contribution cap; and a level-funded plan for stable groups of roughly 15 or more.
Can a small business offer health insurance without a group plan?
Yes. A QSEHRA reimburses employees tax-free up to $6,450 self-only or $13,100 family for 2026. An ICHRA does the same with no cap on the amount you contribute.
How many employees do you need for small business health insurance?
The small group market generally starts at one employee and runs to 50, with some states extending to 100. A self-employed person with no employees shops the individual market instead.
Do part-time employees have to be offered health insurance?
It depends on your plan document and your FTE count. If your eligibility threshold is 30 hours a week, someone averaging above it is eligible under your own terms. Measure average hours from payroll rather than from the schedule.
What is the difference between a QSEHRA and an ICHRA?
A QSEHRA is limited to employers under 50 FTEs, caps reimbursement by law, and cannot run alongside a group plan. An ICHRA has no size limit and no cap, and lets you set different contributions for defined employee classes.
Start with your FTE count
Before comparing a single quote, pull twelve months of payroll hours and calculate your full-time equivalent count month by month. That one figure tells you whether QSEHRA is open to you, whether ACA employer rules apply, and whether the tax credit is in range.
Owners who skip it tend to shop for plans they do not qualify for, or qualify for options they never knew existed.
