How Many Employees Do You Need for Group Health Insurance?

Group health insurance sounds like something only bigger companies offer, so a lot of small business owners never look into it seriously. The truth is more specific than "big enough." There are actual employee-count rules that determine whether you can even buy a group plan, and a separate, more practical question of when it starts making financial sense. Here’s how both of those thresholds actually work.

The Legal Minimum: You Need at Least One Real Employee

This is the part that surprises a lot of solo business owners. To qualify for small group health insurance, you generally need at least one common-law employee besides yourself, and that person can’t be your spouse or another family member. The IRS common-law test looks at whether you control both the work someone does and how they do it. A genuine employee you supervise counts. A 1099 contractor generally doesn’t, since you typically don’t direct their day-to-day work the same way.

That means:

• If you’re the only person working in your business, you’re a sole proprietor for insurance purposes, even if you pay yourself a salary, and you’ll need an individual health insurance plan instead of group coverage.
• If it’s just you and your spouse, the same applies. You still need at least one other, unrelated common-law employee enrolled in the plan to qualify as a group.
• Once you have one qualifying employee who enrolls, you can typically purchase small group coverage, and you can then also enroll your spouse as a dependent on that plan.

If you’re in the first two categories, our Individual & Family Health Insurance page covers the options available to you directly.

2 to 5 Employees: Technically Eligible, Often Impractical

Once you have at least one qualifying employee, you’re technically eligible for small group coverage in Texas, which generally applies to businesses with 1 to 50 full-time equivalent employees. In practice, this size range is where things get complicated.

Most small group plans require a minimum participation rate, commonly around 70% of your eligible, uninsured full-time employees, before a carrier will approve the group. With only a handful of employees, even one or two people declining coverage can drop you below that threshold and disqualify the whole group. There’s a helpful exception: if you enroll during the guaranteed-issue window each year, typically November 15 through December 15, that participation requirement is generally waived.

At this size, an ICHRA (Individual Coverage Health Reimbursement Arrangement) is often worth a serious look as an alternative. ICHRAs don’t have a minimum participation requirement, and you set a defined reimbursement amount rather than committing to a group plan’s premium. Our ICHRA vs. traditional group health insurance in Texas article compares the two directly.

5 to 20 Employees: Group Coverage Starts to Make Practical Sense

Somewhere in this range, group coverage typically shifts from technically possible to genuinely useful. With more employees sharing the plan, hitting the 70% participation requirement becomes more realistic, and you have a wider set of fully insured HMO, PPO, and other plan types to actually compare. Our Best Group Health Plan Types for Small Businesses guide walks through those options in more detail.

This is also the size where offering coverage tends to start paying off for hiring and retention in a competitive DFW job market, since candidates comparing job offers increasingly expect it as a standard benefit rather than a bonus.

20 to 50 Employees: More Leverage, More Options

Businesses in this range are still considered small group under Texas rules, but the larger, more predictable employee base opens up more choices. Level-funded plans, which combine a consistent monthly payment with the possibility of a refund in a good claims year, tend to become a realistic option here, since carriers generally want a large enough group to make that structure work. Our guide on level-funded plans for Texas small businesses explains how that structure functions.

If your business is nearing 25 full-time equivalent employees, it’s also worth checking whether you might qualify for the Small Business Health Care Tax Credit before you cross that line, since eligibility depends on staying under that threshold along with a few other requirements. Our Small Business Health Insurance Tax Credits in Texas article covers the specifics.

50 or More Full-Time Equivalent Employees: It Stops Being Optional

This is the threshold where the conversation changes entirely. Once your business reaches 50 or more full-time employees, including full-time equivalents, you become what the IRS calls an Applicable Large Employer (ALE), and offering coverage is no longer just a business decision. Full-time equivalents are calculated by adding up the monthly hours of your part-time staff (capped at 120 hours per employee) and dividing by 120, which can push a business into ALE status faster than expected once part-time hours are combined.

As an ALE, your business generally must offer minimum essential coverage that’s affordable and meets minimum value standards to full-time employees, or risk a penalty under the ACA’s employer shared responsibility rules. For 2026, those per-employee penalty amounts increased to $3,340 for failing to offer coverage at all, and $5,010 for offering coverage that’s inadequate or unaffordable, according to current IRS guidance. ALE status is also based on your prior year’s workforce, so it’s worth checking your numbers before you assume you’re still under the line.

At this size, self-funding with stop-loss coverage also becomes more financially realistic, since a larger group creates a bigger, more predictable claims pool. Our guide on self-funded vs. fully insured health plans in Texas walks through that decision. Because ACA compliance carries real financial risk once you cross into ALE territory, it’s worth confirming your specific obligations with a tax professional or benefits attorney in addition to a licensed agent.

So, How Many Employees Do You Actually Need?

There’s no single right answer, since "eligible" and "makes sense" are two different questions. You can technically qualify for group coverage with just one non-owner employee, but the participation rules and cost efficiency usually don’t favor group coverage until you’re in the 5 to 20 employee range. Past 20, you gain more plan options and negotiating leverage. Past 50, coverage becomes a compliance requirement rather than a choice.

The honest answer for your specific business depends on your current headcount, how many of those employees would actually enroll, and your budget, not a generic rule of thumb.
