What Is Group Health Insurance?

If you are a Texas business owner thinking about offering health benefits, you probably have one immediate question: what exactly is group health insurance and how does it actually work?

Group health insurance is a single health plan purchased by an employer that covers a group of employees  and usually their dependents under one policy. The employer and employees split the monthly premium, which makes the coverage more affordable than buying an individual plan on the open market.

At Wilkerson Insurance Agency, we work with Texas businesses every week to help them set up group benefits that fit their workforce and their budget. This guide covers what you need to know before making a decision.

Here is what this guide covers:

• How group plans differ from individual coverage
• How premiums, deductibles, and cost-sharing work
• The main plan types available in Texas
• Who qualifies and when they can enroll
• What Texas employers are required to offer under federal law
• How to choose the right plan for your team

What Makes Group Health Insurance Different from Individual Coverage?

A group health plan covers all eligible employees under one shared policy. Individual health insurance covers one person who applies, qualifies, and pays on their own.

The biggest practical difference is risk pooling. When an insurer covers a group, it spreads financial risk across all members. Some employees will use the plan heavily; others will barely touch it. That balance lets the insurer offer lower rates than it would charge someone applying alone.

For your employees, this means access to coverage they might not qualify for or afford independently. For you as the employer, it creates a benefit that helps attract and keep good people. According to the Kaiser Family Foundation, employers covered roughly 73% of the average annual family premium in 2024  and employer-paid premiums are generally tax-deductible as a business expense.

How Do Group Health Insurance Premiums and Cost-Sharing Work?

You are probably asking yourself how the money actually flows. Let me walk you through it.

A premium is the fixed monthly amount paid to keep the plan active  whether or not anyone uses medical services that month. You pay part of it; your employees pay the rest through payroll deductions, usually pre-tax.

Beyond premiums, employees also share costs when they use care. Three terms matter most:

• Deductible: The amount an employee pays out of pocket before the plan starts covering most services. A $1,500 deductible means the employee covers that amount first each plan year.
• Copay: A flat fee paid at the time of a visit (e.g., $30 for a primary care appointment). Some plans apply copays before the deductible is met for certain services.
• Out-of-pocket maximum: The most an employee will pay in a plan year. Once that limit is hit, the insurer covers 100% of covered services for the rest of the year.

After the deductible is met, many plans use coinsurance  for example, the insurer pays 80% and the employee pays 20% until the out-of-pocket maximum is reached. To see current realistic pricing for Texas businesses, read our detailed breakdown of group health insurance costs in Texas.

What Types of Group Health Plans Are Available in Texas?

The plan type determines which providers employees can use and how their costs are structured. This choice affects both your monthly budget and your employees’ experience using the coverage.

HMO Plans

A Health Maintenance Organization requires employees to choose a primary care physician and get referrals for specialists. Coverage is limited to in-network providers except in emergencies. Premiums are lower and cost-sharing is predictable, which makes HMOs a good fit for cost-conscious employers. For a deeper look at how these plans balance cost and convenience for Texas teams, see HMO vs PPO vs EPO vs POS – which health plan is right for your family in Dallas.

PPO Plans

A Preferred Provider Organization gives employees the freedom to see any doctor or specialist without a referral, including out-of-network providers at a higher cost. PPOs cost more in premiums but are preferred by employees who want flexibility or have established care relationships.

HDHP Plans Paired with HSAs

A High Deductible Health Plan carries a higher deductible and a lower monthly premium. When paired with a Health Savings Account (HSA), employees can set aside pre-tax dollars to cover costs until the deductible is met. This structure works well for younger, healthier employees who do not expect frequent medical visits.

EPO and POS Plans

An Exclusive Provider Organization requires in-network providers but does not need a PCP referral for specialists. A Point of Service plan blends HMO and PPO features  you need a PCP, but some out-of-network coverage is available at a higher cost share.

The right fit depends on your workforce demographics, the carrier networks in your area, and what your employees actually value. A licensed Texas broker can compare these options across multiple carriers so you are not guessing. Many Texas employers are also exploring hybrid options like level-funded plans. Read our guide on level-funded plans for Texas small businesses.

Who Qualifies for Group Health Coverage and When Can They Enroll?

Full-time employees working 30 or more hours per week are the standard eligible group under ACA rules. Many employers extend coverage to part-time workers as well, though smaller businesses are not required to do so.

Eligible dependents typically include:

• A legal spouse
• Biological, adopted, or step-children under age 26
• Domestic partners (varies by plan and employer policy)

Under federal law, adult children can stay on a parent’s employer plan until age 26, regardless of whether they live at home, attend school, or work elsewhere.

Employees can enroll during their initial eligibility window or the annual open enrollment period. Outside those windows, enrollment is only allowed after a qualifying life event, marriage, divorce, birth, adoption, or loss of other coverage. Missing an enrollment window can leave an employee uninsured for months, so clear communication from the employer matters.

What Are Texas Employers Required to Offer?

Before you decide anything, you need to understand where you stand legally.

Employers with 50 or more full-time equivalent (FTE) employees  called Applicable Large Employers (ALEs)  must offer minimum essential coverage to full-time employees and their dependents. If they do not, and at least one employee receives a premium tax credit through the marketplace, the employer may face a federal penalty under the ACA employer shared responsibility rules.

Employers with fewer than 50 FTEs are not required to offer coverage under federal law. That said, many Texas small businesses choose to offer it because it makes hiring and retention significantly easier in a competitive market.

Small businesses with fewer than 25 FTE employees may qualify for the Small Business Health Care Tax Credit if they pay at least 50% of employee-only premiums and purchase coverage through the SHOP marketplace. More details are available at Healthcare.gov.

If you are unsure how to count your FTEs correctly since part-time hours factor into the total, a broker can help you run the numbers before making any commitments.

Frequently Asked Questions

How many employees do I need to offer a group health plan in Texas?

Most carriers require at least two enrolled employees to issue a group policy. There is no federal requirement to offer coverage if you have fewer than 50 FTEs, but you still need a minimum group size to qualify for group rates.

Can employees opt out of group health insurance? 

Yes. Employees can waive coverage by signing a declination form. Common reasons include being covered under a spouse’s plan or qualifying for Medicare. Most carriers require 50% to 75% of eligible employees to enroll for the policy to be issued.

Are the premiums I pay tax-deductible? 

Employer-paid premiums are generally deductible as a business expense. Employee contributions made through a Section 125 plan are excluded from federal income and payroll taxes. Speak with your tax advisor to confirm how this applies to your business structure.

What happens to an employee’s coverage when they leave? 

Under COBRA, former employees can continue group coverage for up to 18 months by paying the full premium plus a small administrative fee. Employers with fewer than 20 employees fall under Texas state continuation rules rather than federal COBRA. 

Can I offer different plan levels to different employee groups? 

Yes, within limits set by ACA non-discrimination rules. You can offer a richer plan to full-time employees and a basic option to part-time workers, as long as the distinction is based on a legitimate employment classification and not health status.

Taking the Next Step for Your Business

Choosing a group health plan is one of the most practical decisions you can make as a Texas employer. It protects your employees, reduces your tax burden, and gives your business a real hiring advantage.

Three things to carry away from this: group health insurance lowers costs by spreading risk across your workforce. The plan type you choose  HMO, PPO, or HDHP  shapes how employees access care and what they pay out of pocket. And if you have 50 or more full-time equivalent employees, federal law creates specific obligations that carry financial consequences if ignored.

The right plan looks different for every business, which is why a one-size-fits-all answer does not exist here.
