Open Enrollment for Small Employers: A 90-Day Timeline for Texas Businesses

Open enrollment for small employers goes badly for one reason more than any other: it starts too late. A renewal letter lands in the mail, the owner has three weeks to decide, and everyone signs whatever is in front of them. Ninety days is enough runway to actually shop the plan, fix the paperwork, and hold real employee meetings. Here is what that timeline looks like for a Corpus Christi business, and which deadlines are legal ones rather than preferences.

First, know which rules apply to you

In Texas, a small employer is generally a business with 2 to 50 eligible employees. The Texas Department of Insurance explains that small employer plans are guaranteed issue — a carrier cannot turn your group down because of someone’s health — and that premiums are based mainly on employee age, not on the health history of your workforce. Guaranteed issue is written into the Texas Insurance Code at Section 1501.151.

Guaranteed issue does not mean no rules. Carriers may apply participation and contribution requirements, and federal market rules let a small group carrier limit availability to an annual window of November 15 through December 15 for a group that cannot meet them (TDI’s health carrier FAQ, citing 45 CFR 147.104(b)(1)). That single sentence is why a January 1 renewal handled in December can leave you with no options at all.

Day 90 to 75: pull your own numbers first

Start with facts you already own. Current plan documents, the carrier’s renewal or rate history, your enrollment count by tier, what you contribute per employee, and your employee census with dates of birth. Since Texas small-group rates are age-rated, a census with accurate birth dates is the difference between a real comparison and a guess.

Day 75 to 60: decide what you are actually solving for

Small employers usually want one of three things: hold the cost flat, improve the plan without a large increase, or reduce the administrative load./p>

It is also worth deciding what sits alongside the medical plan. Dental, vision, life, disability, and voluntary lines are frequently what employees actually notice, and they cost the employer far less than a medical buy-up. Our employee benefits for Corpus Christi employers overview and the Corpus Christi benefits page walk through how those layers usually get stacked for a small group.

Day 60 to 45: shop, and read past the premium

Deductibles, out-of-pocket maximums, network breadth, and prescription tiers all move the real cost to your employees. So does the funding model — a level-funded arrangement behaves differently from a fully insured plan, which we covered in our post on level-funded versus fully insured plans.

Ask for the Summary of Benefits and Coverage for every option. The SBC is a standardized federal document, so it is the one place where two carriers describe themselves the same way. Under 29 CFR 2590.715-2715, plans must supply the SBC at specific points, including with open enrollment materials, and must give 60 days’ advance notice of a mid-year material modification that would change the SBC’s content.

Day 45 to 30: the notices you owe

This is the part small employers miss, because nobody sends a reminder. Depending on your plan, the list typically includes:

  • Medicare Part D creditable coverage notice — if your plan covers prescriptions, CMS requires notice to Medicare-eligible individuals of whether the drug coverage is creditable, before October 15 each year.
  • Disclosure to CMS — the same rules require an online disclosure to CMS of creditable status within 60 days after the start of the plan year, within 30 days after the plan terminates, and within 30 days after a change in creditable status.
  • Employer CHIP notice — the U.S. Department of Labor requires an annual notice to employees about possible premium assistance under Medicaid and CHIP, and publishes a model notice.
  • WHCRA notice — the Women’s Health and Cancer Rights Act requires notice of mastectomy-related benefits at enrollment and annually after that (ERISA section 713(a)).
  • SBC and SPD — the SBC with enrollment materials, and a current summary plan description for the ERISA plan.

Open enrollment is the natural time to distribute the annual ones together, which is why the notice packet should be assembled before the meetings, not after.

Day 30 to 15: hold the meetings and set the election window

Schedule the meeting, give people the documents in advance, and be explicit about the election deadline.

The deadline matters more than most owners realize. If employees pay their share pre-tax through a Section 125 cafeteria plan, elections are generally locked in for the plan year. Under 26 CFR 1.125-4, a plan may allow a mid-year change only when a permitted change in status occurs — marriage, divorce, birth or adoption, a change in employment status, and similar events — and the change has to be consistent with the event. “I picked the wrong plan in November” is not on that list.

Two related Texas rules are worth stating in the meeting: TDI’s small employer guide says you must give new employees at least 31 days from their start date to enroll, and employees who miss that window generally wait for the next open enrollment unless they have a special enrollment right.

Day 15 to day 1: submit, confirm, and check the first invoice

Get signed elections and waivers back, submit enrollment to the carrier, and confirm that ID cards and portal access are live before the effective date.

Then check the first invoice against your own enrollment list, line by line. After the plan year begins, calendar the follow-on items: the CMS disclosure within 60 days of the plan year start, and, if your plan is self-insured or level-funded, the IRS reporting that comes with it — 1095 forms are furnished to individuals by March 2 for the prior calendar year, per the IRS instructions for Forms 1094-C and 1095-C.

Check these nine things on your own plan

  1. What is your renewal date, and what is 90 days before it?
  2. Does your census have correct dates of birth for every eligible employee?
  3. What percentage of the premium do you contribute, for employees and for dependents?
  4. Does your carrier apply a participation or contribution requirement you are close to missing?
  5. Do you have an SBC for the current plan, and did employees receive it?
  6. Did you send the Part D creditable coverage notice before October 15, and complete the disclosure to CMS?
  7. Did the CHIP and WHCRA notices go out this plan year?
  8. Is your Section 125 plan document current, and does it match how you actually handle mid-year changes?
  9. Do you have signed elections and signed waivers on file for everyone eligible?

What an independent agency does with this

As an independent agency, we are not tied to one carrier’s product, so the comparison can start with what your group needs rather than with what one company sells. We work the same way on the property and casualty side for local businesses — see business insurance in Corpus Christi and Texas workers’ compensation — and the benefits and commercial calendars usually deserve to be looked at together.

If this is your first plan rather than a renewal, start with what to ask a carrier about group health insurance in Corpus Christi.

Our free coverage review is a straightforward conversation: we look at what you have now, what your renewal timeline is, what notices are outstanding, and where the gaps are. No cost, no obligation, and you keep the summary either way. If your renewal is inside 90 days, that is a good reason to start this week rather than next month.

This article is general information for Texas employers and is not a coverage opinion, legal advice, or tax advice. Whether a specific rule applies to your business depends on your plan documents, your carrier’s terms, and your employee count.
