Group Health Insurance for 100+ Employees in Texas: What Changes at 100 and 250

Group health insurance for 100 or more employees in Texas changes in three ways at 100: federal reporting starts, Medicare pays second for disabled workers, and carriers read your claims history instead of your headcount. We write groups at 100+ and 250+ employees, and our broker cost to the employer is $0.

We are an independent employee benefits brokerage based in Corpus Christi and licensed across Texas. Texas calls an employer large at 51 employees, so the 100 line is not a Texas legal switch. It comes from federal rules and from how the market underwrites. 40 Google reviews.

What changes at 100 employees

Five lines matter to a Texas employer between 50 and 250 employees. Only the first is Texas law.

Line	Where it comes from	What it means for you
51 employees	Texas Insurance Code, section 1501.002	You are a large employer. Small-employer rating rules stop applying.
50 full-time equivalents	Federal Applicable Large Employer rules	Offer and affordability reporting starts. Texas employer health insurance requirements covers it.
100 participants	Department of Labor rule, 29 CFR 2520.104-20	A plan with fewer than 100 participants on the first day of the plan year can be exempt from the annual Form 5500. At 100 or more, the plan files.
100 employees	Medicare Secondary Payer rules	For a disabled Medicare beneficiary covered through current employment, your plan pays first. Under 100, the disability rule does not apply.
250 Forms W-2	IRS Form W-2 instructions	Reporting the cost of coverage in Box 12, Code DD, is optional for employers filing fewer than 250 and applies to larger filers. It is informational, not taxable.

The Form 5500 test counts plan participants on the first day of the plan year, so your accountant or plan administrator confirms the number. A fully insured plan at 100 or more participants files with the insurance schedule and does not need an independent audit. Self-funded plans have their own filing rules. We are not your accountant or your ERISA counsel, and we tell you where their sign-off belongs before the quote, not after.

The working-aged Medicare rule starts much lower, at 20 employees. The 100 line is the disability rule only.

Three funding lanes for a 100+ group

Three lanes can go on the sheet: fully insured, level-funded, and self-funded.

• Fully insured. The carrier takes the claims risk for a fixed premium.
• Level-funded. You pay a fixed monthly amount, part of which funds claims, and stop-loss covers the downside. A healthy group often lands 15% to 30% under a comparable fully insured quote. That is a planning range, not a promise on your census.
• Self-funded. The employer funds claims through an administrator and buys stop-loss. It is not automatic at any headcount. Cash flow, claims predictability, and administrative capacity decide whether it belongs on the sheet.

We quote all major carriers and several regional ones, fully insured and level-funded when they fit. No one carrier fits every large group. Self-funded vs level-funded compares the two lanes that carry claims risk, and the large group pillar shows all three side by side.

How a 100+ group gets priced

A carrier prices a 100+ group on its own claims and its own census. Texas Insurance Code section 1501.610 bars an adjustment to premium for an individual employee's health status, but it does not restrict the amount a large employer may be charged for coverage. That is why we ask for the claims report first.

Under Texas Insurance Code chapter 1215, a plan sponsor can request that report in writing. The carrier has 30 days to send it, and it covers up to 36 months of paid claims, premium, and covered employees by tier. A clean report lets the market quote your real risk instead of a guess.

Three things move the number most at 100+:

• Claims history. Large claims especially shape both the quote and the stop-loss terms.
• Census. Age, dependents, and ZIP mix set the baseline.
• Plan design and contribution. Your employer share and plan options are the part you control.

At this size a formal request with plan design, networks, and service terms on one timeline is usually worth the calendar. Allow 60 to 90 days when you can. Issued quotes are the answer, so we do not name a rate before the market responds.

At 250 and more employees

The same independent process applies, with more depth. At 250+ the Form W-2 cost reporting applies, self-funded is worth pricing next to the other two lanes, and a group with several sites or states needs the network and situs questions answered before the quote, not after. There is no size cap on the groups we write.

Multiple sites and multiple states

Employers at 100+ often have more than one worksite. Send every work location and every home state on the census. Situs, carrier access, and which entity holds the policy all depend on that footprint. Multi-state group health insurance explains what we can and cannot promise before we see the census.

What to send for a 100+ quote

• Census. Eligible employees with date of birth, gender, and home ZIP. Add dependents if you want family tiers.
• Current plan and contribution. The plan design, your employer share, and the renewal date.
• Claims or the renewal letter. Send what you have. We request the formal claims report if you do not have one.
• Hospitals and campuses. Name the ones your people use, by campus and not by logo alone.
• Locations. Every worksite and every state where employees live or work.
• Funding preference. Fully insured, level-funded, self-funded, or a side-by-side.

What it costs the employer

Our broker cost to the employer is $0. Carrier commission is already inside the published premium whether you use a broker or go direct, so skipping the broker does not lower your rate. On a level-funded quote, we set our PEPM, our per employee per month amount, in the quote. It sits inside the monthly carrier payment, never as a separate bill. PEPM vs commission explains the models.

For planning only, full single medical runs about $625 to $680 per employee per month in 2026, and a 50% employer contribution to employee-only is about $313 to $340 per enrolled employee. Group health insurance cost for Texas small business shows how we build the band. Those are estimates, not a 100+ quote.

Frequently Asked Questions

Does Texas treat a 100-person employer differently from a 60-person one?

No. Texas draws its large-employer line at 51 employees. The differences at 100 come from federal rules and from how carriers underwrite.

Do you only work small businesses?

No. We shop groups at 100+ and 250+ employees with no cap on size, through the same independent process as smaller groups. Texas employee benefits broker covers how we work across the state.

Who files the Form 5500?

The plan administrator files it, usually with the employer's accountant. We flag the 100 line during the quote so the filing is planned, and your accountant or counsel confirms the details.

How early should we start?

Build 60 to 90 days when you can. The Texas claims report can take up to 30 days to arrive, and a 100+ group usually needs time for underwriting questions.
