Traditional group health insurance is a type of health insurance plan employers offer their employees and their families at a discounted premium rate. Because of its familiarity and tax benefits, group health insurance is a sought-after employee benefit. It can help employers attract and retain talented workers.
There are two sizes of group health insurance: small and large. Both small and large group health insurance plans have pros and cons. While they do have similarities, there are some key differences. Whether an employer can secure small or large group health insurance mainly depends on their company size.
This article explores small and large group health insurance, how they compare, and why employers should consider a health reimbursement arrangement (HRA) as a flexible and budget-friendly alternative.
Takeaways from this blog post:
- In most states, small group health plans are for employers with between two and 50 employees. Large group health plans are for organizations with 51 or more employees.
- Small and large group health plan premiums vary. However, small group plans can be more expensive for employers and don’t allow for insurance rate negotiations, like large group plans.
- Group health plans have annual premium rate hikes and aren’t as flexible for employees as health reimbursement arrangements (HRAs), which allow for tax-free reimbursements for medical expenses.
Small group health insurance is a health plan that small employers offer their employees. Most states define a small group as an organization with between two and 50 employees. However, some states consider a company with between two and 100 employees a small group.
The Affordable Care Act (ACA) only requires employers with 50 or more full-time equivalent employees (FTEs) to offer health insurance. However, many employers with fewer than 50 FTEs still choose to do so, as providing comprehensive coverage is a great way to make your company and benefits package more attractive to employees.
To qualify for a small group health insurance plan, you must:
There are various types of small group health plans available. However, all small group plans must meet ACA requirements. This means insurers must classify them using the metallic tiers of coverage—bronze, silver, gold, and platinum—and cover the essential health benefits. These include emergency services, prescription drug coverage, hospitalization, and more.
Small group plans must also meet a specific medical loss ratio, which means they must spend at least 80% of their premium income on medical-related expenses and no more than 20% on administration costs.
You can purchase a small group plan through an insurance company, agent, or broker anytime during the year. If you buy your plan on the SHOP marketplace, you may qualify for the Small Business Health Care Tax Credit to save on premium costs.
As the name suggests, large group health insurance is for larger organizations. Most states consider a large group an employer with 51 or more employees. However, some states define it as an organization with 101 employees or more.
The ACA’s employer mandate requires all applicable large employers (ALEs)—or those with at least 50 FTEs—to offer their employees affordable health insurance with minimum essential coverage (MEC) and minimum value or face tax penalties. Most ALEs choose a group health insurance policy to satisfy the employer mandate.
To qualify for large group health insurance options, you must:
The biggest difference between small and large group health insurance is group size. But there are other differences. For example, small group plans must offer medical coverage for the essential benefits. However, large group plans are exempt from this requirement.
Additionally, the ACA requires large group markets to spend at least 85% of premiums on medical-related expenses, leaving no more than 15% for administrative costs.
Large group plans don't have to use the metallic tiers classification either. This gives insurance providers greater flexibility with their plans. Insurers can also offer add-on coverage options to large group plans, such as ancillary benefits, for an extra cost.
Like small group health insurance, employers can purchase a large group plan anytime during the year. However, eligible employees typically can only enroll during the plan’s annual open enrollment period unless they qualify for a special enrollment period.
Small and large group health plan premiums vary based on several factors. For example, small group plans must follow specific ACA guidelines. This means insurers can only use age, family size, location, tobacco use, and plan type to determine the premium rate. Depending on your type of workforce, this can make small group plans very expensive. Small employers can't negotiate or receive discounts once the insurer sets the rate.
Insurers can use more factors to determine large group insurance premiums, like the number of participating employees, sum insured, industry, the company’s claims history, and add-ons. Insurers underwrite large groups as one group, meaning they consider all employees an equal risk and charge an equal amount. But, employers or brokers can negotiate the rate with the insurer. And, if they choose add-ons, they may be able to receive a bundling discount.
But to give you an idea of the average costs, let’s look at some numbers. According to KFF, the average annual premium for group health insurance in 2023 was $8,435 for self-only health coverage and $23,968 for family coverage3. These figures represent averages for small and large group policies combined. Of these amounts, employers contributed an average of $7,034 annually toward self-only plans and $17,393 toward family plans.
To break it down further, the average annual premium for self-only coverage was $8,722 for small businesses and $8,321 for large companies. Family coverage was $23,621 for small employers and $24,104 for large employers. KFF considers small businesses to have between three and 199 workers and large companies to have 200 or more workers.

Group health insurance is often the first thing that comes to mind when to small or large employers consider a health benefit. However, it comes with annual rate hikes and a lack of flexibility for employees, which can make it unappealing in the long run. That’s why many organizations have switched to more personalized and flexible alternatives, like an HRA.
An HRA is an IRS-approved employer-funded health benefit that allows employers of all sizes to reimburse their employees tax-free for more than 200 qualified medical costs. Depending on the type of HRA you offer, you can also reimburse your employees for their individual plan premiums.
Instead of working with an insurance company, you set a monthly HRA allowance. This is the most you’ll spend each month per employee. Your employees buy eligible medical services and items out-of-pocket. Then, your employees submit proof of their purchases for review to ensure the expenses comply with IRS regulations. Once you approve the expense, you reimburse your employees up to their allowance amount.
An HRA helps you control your benefits budget. Unlike group health plans, you won’t experience any annual rate hikes unless you increase your HRA’s allowances. This is especially impactful for small employers.
“Due to the smaller risk pool [of small group plans], one high claim can significantly impact overall costs. However, small businesses can leverage HRAs to offset high deductibles, achieving a balance between cost control and employee satisfaction,” says John Crist, founder of Prestizia Insurance.
HRAs also have tax benefits. All reimbursements are tax-free for employers and income-tax-free for employees if they meet the participation requirements.
You can administer three types of HRAs with PeopleKeep:
No matter your company size or budget, there’s a customizable HRA for you and your employees.
Group health insurance coverage continues to be a popular employee benefit across the U.S. However, its cost, participation requirements, and rigid structure may not make it the right choice for every employer’s needs. Luckily, more modern health coverage options are available for small and large companies.
Personalized health benefits, like an HRA, offer more savings and customization for employers of all sizes. Better yet, they provide employees and their families greater flexibility and control over their medical decisions.
