Most small group health plans need three out of four eligible employees to sign up. For one month every year, federal law says that rule cannot keep you out. Here is how the window works, and how to use it properly.

The short answer

Carriers normally only sell a small group health plan if enough of your eligible employees enroll — in Texas, usually 75 percent — and if you as the employer pay a minimum share of the premium, often 50 percent. Miss either number and a carrier can turn your application down.

Except between November 15 and December 15. During that window, federal law requires carriers to accept small groups that fall short of their participation or contribution rules. That month is what brokers call the participation holiday, and for a business that has been told it is too small or too patchy to qualify, it is the one reliable way in.

Why participation rules exist in the first place

A group health plan only works if the healthy employees are in it alongside the ones who need care. If only the people expecting large medical bills sign up, the plan’s costs spiral and the carrier loses money on every group like it. Insurers call this adverse selection, and minimum participation is their defence against it.

Contribution rules do the same job from a different angle. When the employer pays a meaningful share of the premium, coverage is cheap enough for young and healthy employees to join. When the employer pays little or nothing, those are exactly the people who opt out.

The Texas Department of Insurance puts the typical requirement plainly: most carriers require at least 75 percent of your full-time employees to participate, and a carrier might require you to pay at least 50 percent of your employees’ premiums. In Texas, a small employer is a business with two to 50 employees.

How the participation holiday works

The rule sits in the federal guaranteed availability regulation, 45 CFR 147.104. It says carriers in the small group market must let an employer buy coverage at any point in the year — with one exception. If a group cannot meet the carrier’s contribution or participation rules, the carrier is allowed to restrict that group to an annual enrollment period that begins November 15 and runs through December 15.

Read that the other way round and you have the holiday. For eleven months of the year, low participation is a legitimate reason to decline you. For that one month, it is not. The carrier has to take the application.

Guaranteed availability also means a carrier cannot decline your group, or price it higher, because of anyone’s health. Small group rates in Texas are set by age, location, tobacco use and family size, not medical history. The holiday removes the last common reason a small business gets told no.

This is not a goodwill gesture that a carrier may or may not extend. It is federal law, and it covers the employer contribution minimum as well as participation. You do not have to ask nicely.

How participation is actually counted

The single most common mistake we see is an owner counting every employee, getting a low percentage and assuming the plan is out of reach. Employees who already have health coverage elsewhere — through a spouse’s employer, Medicare, Medicaid or TRICARE — generally do not count against you. They sign a waiver and drop out of the calculation.

Here is how that plays out for three hypothetical Coastal Bend businesses:

Key dates for this year

The 2026 window opens on Sunday, November 15, so in practice the first business day is Monday the 16th. It closes on Tuesday, December 15. Most groups that use the holiday start coverage on January 1, 2027.

December 15 is the last day, not the target. Carriers set their own submission requirements inside the window, and an application missing a census detail or a signature can stall past the deadline while it is corrected. Treat mid-November as the deadline and December 15 as the safety net.

Now through early November — gather your employee census, identify who has coverage elsewhere, and get quotes side by side.
November 15 — the window opens. Submit as early as you can.
December 15 — the window closes. Applications must be complete, not just started.
January 1, 2027 — the usual coverage start date for groups enrolling in the window.

What the holiday does not cover

It applies to fully insured small group plans. Level funded plans are technically self funded — a claims fund backed by stop-loss insurance, run by a third-party administrator — and guaranteed availability does not bind them. Level funded carriers keep their own participation minimums all year round, so if a level funded quote is what you are after, you still need to meet its rules.

It does not guarantee renewal on the same terms. Federal rules let a carrier non-renew a group that still falls short of its participation or contribution requirements when the plan comes up for renewal. Plenty of carriers renew these groups anyway, but you should go in with a plan for year two — whether that is lifting participation, or simply returning through the next November window.

And it does not change the price. The holiday opens the door; it does not discount the plan. Your rates are the same ones any small group of your size and makeup would pay.

Who should use it

The holiday was built for a specific kind of business, and it is worth being honest about whether that is you.

Very small groups. At four or five employees, one person declining can drop you below 75 percent on its own. The holiday takes that arithmetic off the table.
Young workforces. Employees in their twenties often decline coverage to keep the paycheque. The holiday lets you offer the plan to the ones who want it without needing the ones who do not.
Tight budgets. If paying half of every employee’s premium is not realistic yet, the holiday lets you start with a smaller contribution and build from there.
Businesses turned down before. If a carrier declined you on participation earlier this year, you are exactly the group this window was written for.

Why the paperwork is worth getting right

The holiday is simple in principle and fiddly in practice. Each carrier counts eligible employees slightly differently, sets its own submission requirements inside the window, and prices the same census differently. An application that goes to the wrong carrier in the second week of December leaves no time to try another.

That is where an independent broker earns its keep. We run your participation numbers against the carriers we represent before you submit, compare the plans side by side, and file the application early enough that a missing document is an inconvenience rather than a missed year. If group coverage still does not fit, we will tell you that too — and walk you through the alternatives, including an individual coverage HRA, which has no participation requirement at all.

Were you turned down on participation before?

Send us your employee count and tell us who already has coverage somewhere else. We will run the participation math, tell you whether you qualify year-round or only in the November window, and have your application ready before November 15. It costs nothing. We place group benefits and Medicare coverage across twelve carriers.

Common questions

The follow-ups we field most often after this conversation.

It is the annual window from November 15 to December 15 when health insurance carriers must accept small group applications even if the employer does not meet the carrier’s minimum participation or employer contribution requirements. It comes from the federal guaranteed availability rule, 45 CFR 147.104, and applies to fully insured small group plans.
