Small Group Health Insurance: A Guide for Small Employers

Offering small group health insurance is one of the most effective ways for small employers to attract and retain talent. If your business has between 1 and 50 full-time-equivalent employees, you fall into the small group health insurance market, which comes with specific rules, pricing structures, and potential tax advantages that differ significantly from large-group and individual coverage.

This guide explains how small group plans work in 2026, roughly what they cost, and how to choose the right option for your business and your team. Because many of the dollar figures below are set by law and adjusted every year, treat them as current-as-of-2026 estimates and verify the latest numbers before you rely on them. This is general education, not tax or legal advice. For broader policy context, visit our healthcare policy guide.

What Is Small Group Health Insurance?

Small group health insurance refers to employer-sponsored health plans offered to businesses with 1 to 50 full-time-equivalent (FTE) employees. In a few states — including California, Colorado, New York, and Vermont — the small group definition extends to businesses with up to 100 employees.

Under the Affordable Care Act (ACA), small group plans must cover the ten essential health benefits, cannot deny coverage or charge more based on pre-existing conditions, and must use modified community rating. That means premiums can vary based on age, tobacco use, geographic area, and plan design — but not based on the health status or claims history of your employees. This is a meaningful protection: one employee’s serious diagnosis cannot spike your group’s rates.

Unlike applicable large employers (generally 50 or more FTEs), small employers are not subject to the ACA’s employer mandate and face no penalty for not offering coverage. Many still offer it, because health benefits are a powerful recruiting and retention tool.

How Small Group Premiums Are Determined

Pricing in the small group market is more regulated than many employers expect. The permitted rating factors are:

• Employee ages: Premiums adjust for the ages of enrolled employees and dependents. The ACA allows a 3:1 age-rating ratio, so the oldest adult enrollees can be charged up to three times what the youngest adults pay.
• Geographic location: Costs vary by rating area, so urban and rural rates can differ.
• Tobacco use: In most states, insurers can charge tobacco users up to 50% more (some states limit or bar this surcharge).
• Plan design: Richer plans with lower deductibles and copays carry higher premiums. The metal tiers — Bronze, Silver, Gold, and Platinum — correspond to actuarial values of roughly 60%, 70%, 80%, and 90%.

Crucially, the health history or claims experience of the group does not affect small group premiums under ACA rules. That protection is one of the main reasons the small group market is attractive for businesses that would otherwise fear a single large claim.

What Small Group Coverage Costs in 2026

Employer health coverage is expensive and has been rising. In KFF’s most recent Employer Health Benefits Survey, average annual premiums for employer-sponsored coverage were in the neighborhood of $9,000 for single coverage and roughly $26,000 for family coverage, with employees paying a share of that through payroll. These averages cover firms of all sizes; small employers often pay somewhat less per enrollee on average but tend to offer less generous plans. Check KFF’s latest survey for current figures, since they change every year.

Employers typically cover a large share of the employee-only premium and a smaller share of dependent premiums — a common range is 70% to 85% of the employee-only cost and 50% to 70% of dependent cost. The employer’s premium contributions are generally tax-deductible as a business expense.

The SHOP Marketplace

The Small Business Health Options Program (SHOP) is the ACA marketplace for small employers, available to businesses with 1 to 50 employees (up to 100 in some states). Its notable features include:

• Tax credits: Businesses with fewer than 25 FTEs, average annual wages below an inflation-adjusted threshold (roughly $60,000 in recent years — verify the current figure), and that contribute at least 50% of employee premiums may qualify for the Small Business Health Care Tax Credit. The credit can be worth up to 50% of the employer’s premium contribution (25% for tax-exempt employers) and generally requires enrolling through SHOP.
• Flexible enrollment: SHOP has no fixed open-enrollment window — employers can start coverage at any time of year.
• Employee choice: Some SHOP arrangements let employers set a defined contribution and allow employees to choose among plans.

In practice, many small employers work with a licensed insurance broker rather than using SHOP directly. Brokers can access both SHOP and off-exchange small group plans, often offering a wider selection and hands-on enrollment support at no direct cost to the employer, since brokers are compensated by insurers. Note that to claim the tax credit you generally still need a SHOP-qualified plan, so discuss that goal with your broker.

Types of Small Group Plans

Small employers can choose from several plan structures:

• HMO (Health Maintenance Organization): Lower premiums, but employees must use in-network providers and typically need referrals for specialists.
• PPO (Preferred Provider Organization): Higher premiums, but more flexibility to see out-of-network providers without referrals.
• EPO (Exclusive Provider Organization): Network restrictions similar to an HMO, but usually without referral requirements.
• HDHP with HSA: High-deductible health plans paired with Health Savings Accounts offer lower premiums and tax-advantaged savings. For 2026, the IRS-defined minimum HDHP deductible is approximately $1,700 for self-only coverage and $3,400 for family coverage (indexed annually — confirm the current figures).

Many small employers offer a single plan to simplify administration, while others offer two or three options — for example, an HMO and a PPO — to accommodate different employee needs and budgets.

Level-Funded and Self-Funded Options

Beyond traditional fully insured group plans, many small employers now consider level-funded plans. In a level-funded arrangement, the employer pays a steady monthly amount that covers expected claims, administration, and stop-loss insurance, and may receive a refund if claims come in low. These plans are technically self-funded and are regulated differently from fully insured ACA plans, which can mean lower costs for a relatively healthy group but more variability and less of the ACA’s community-rating protection. Larger or growing small businesses sometimes explore full self-funding with stop-loss coverage. These arrangements can save money but shift more risk onto the employer, so weigh them carefully with a broker or benefits advisor.

Alternatives to Traditional Small Group Insurance

Health Reimbursement Arrangements (HRAs)

Instead of buying a group plan, some small employers use an Individual Coverage HRA (ICHRA) or a Qualified Small Employer HRA (QSEHRA) to reimburse employees, tax-free, for individual-market premiums and qualified medical expenses. These let the employer set a fixed monthly allowance while employees choose their own coverage.

An ICHRA has no company-size limit and no annual dollar cap, and it can be structured with different allowances for defined classes of employees. A QSEHRA is available only to employers with fewer than 50 FTEs that do not offer a group plan, and it has annual IRS reimbursement limits that are adjusted each year (in recent years, roughly $6,000+ for self-only and $12,000+ for family coverage — verify the current limits). Reimbursements are generally tax-free to employees and deductible for the employer. HRAs can be a good fit when a group plan is unaffordable or participation requirements are hard to meet.

Association Health Plans

Some small businesses access coverage through trade associations or professional groups. Association health plans let small employers band together for potentially better rates, though the rules governing them have shifted over the years and availability varies by state. Confirm current availability and consumer protections before joining one.

Professional Employer Organizations (PEOs)

A PEO co-employs your workers and provides access to its master health plan, which can offer large-group pricing advantages. This can work well for very small businesses that want a hands-off approach to benefits and payroll administration, though it means outsourcing significant HR functions.

Steps to Set Up Small Group Health Insurance

1. Determine eligibility: Confirm you have at least one W-2 employee other than the owner (in most states) and meet any state-specific participation requirements.
2. Set a budget: Decide how much the business can contribute per employee per month. A common approach is covering 50% to 75% of the employee-only premium.
3. Work with a broker: A licensed broker can present quotes from multiple carriers, explain plan differences, and handle enrollment paperwork at no direct cost to you.
4. Choose a plan (or plans): Select the metal tier(s) and plan type(s) that balance premium cost against employee needs.
5. Enroll employees: Provide enrollment materials and collect the required information. Most carriers set a minimum participation rate (often around 70% of eligible employees).
6. Administer ongoing: Handle monthly premium payments, add and remove employees as needed, and prepare for annual renewal.

Frequently Asked Questions

Am I required to offer health insurance as a small employer?

No. The ACA employer mandate applies only to applicable large employers with 50 or more FTEs. Small employers are not penalized for not offering coverage, though offering small group health insurance can provide tax benefits and helps with recruitment and retention.

Can I offer different plans to different employees?

You can generally offer plan choices to all employees, but you cannot offer different benefits in ways that discriminate based on health status. You can establish classes based on legitimate job-based criteria (such as full-time vs. part-time or salaried vs. hourly) in certain plan and HRA structures. Check the specific rules with your broker or advisor.

What if only a few employees want to enroll?

Most insurers require a minimum participation rate, often around 70% of eligible employees. Employees with other coverage (through a spouse, Medicare, or Medicaid) are usually excluded from that calculation. If you cannot meet participation requirements, an HRA such as a QSEHRA or ICHRA may be a better path.

How does the small business tax credit work?

The Small Business Health Care Tax Credit is available to employers with fewer than 25 FTEs, average annual wages below an inflation-adjusted threshold, that contribute at least 50% of employee premiums for a SHOP plan. The maximum credit is 50% of the employer’s premium contribution (25% for tax-exempt employers), it is generally limited to two consecutive years, and it is claimed on IRS Form 8941. Confirm the current wage threshold and rules with the IRS or your tax professional.

When can I start or change small group coverage?

Unlike individual marketplace plans, small group coverage can begin in any month of the year. Annual renewals typically occur on the plan’s anniversary date, when you can change carriers or plan designs.
