How to prepare for open enrollment: a checklist for small employers

Open enrollment goes badly for a predictable reason: it gets treated as a two-week event in November rather than a process that starts in the summer. By the time most employers begin, the decisions that would have made it easy have already been foreclosed by the calendar.

Here is the version that works, organized by how far out you are.

This is general information, not legal or tax advice. Required notices and deadlines vary with your plan structure and size. Confirm your specific obligations with qualified counsel.

120 days out: decisions

This is the only window where you have real leverage, because it is the only window in which changing carriers or funding structures is still practical.

• Pull your current plan documents, most recent renewal, and a recent invoice
• Calculate your total annual spend, employer and employee share separately
• Review last year's enrollment: who took coverage, who waived, and why
• Decide what you want to change before you see the renewal, so the renewal does not set your agenda for you
• Instruct your broker to go to market, not just to present the renewal
• If you are near 50 full-time equivalents, run the count now rather than in January

If you are an ALE, confirm your affordability safe harbor choice for next year and price your lowest-cost self-only option against it. Getting this wrong is a penalty that surfaces two years later.

90 days out: options on the table

• Review quotes side by side on a like-for-like basis, same deductibles, same network
• Model the employee-side cost for each tier under each option, not just the total premium
• Check whether any network change would disrupt providers your people actually use
• Decide your contribution strategy deliberately rather than carrying last year's percentages forward
• Confirm ancillary lines: dental, vision, life, disability, and whether each still earns its place

A contribution split you set three years ago is a decision you are still making, just without thinking about it. Enrollment follows the employee cost, and enrollment drives your risk pool.

60 days out: lock it down

• Make the final decision and submit carrier paperwork
• Confirm effective dates and that there is no coverage gap at the transition
• Get plan documents, summaries of benefits and coverage, and rate sheets in hand
• Build the enrollment in your payroll or benefits administration system
• Test the deduction amounts against the carrier rate sheet before anyone enrolls
• Schedule enrollment meetings, including shifts and locations that normally get missed

That deduction test is the step employers skip and then regret. A mismatch between what the system deducts and what the carrier bills produces a reconciliation problem that runs all year.

30 days out: communicate

Most enrollment problems are communication problems. Employees do not make bad choices because they are careless; they make them because nobody explained the plan in language they use.

• Send the announcement with dates, what is changing, and what it costs at each tier
• Distribute required notices: summary of benefits and coverage, CHIP, Medicare Part D creditable coverage, and any others your plan triggers
• Hold meetings where the work happens, in Spanish where your workforce needs it
• Publish a plain-English comparison of the options, in dollars per pay period rather than per month
• Tell people explicitly what happens if they do nothing

That last point matters more than it sounds. If failing to act means defaulting into last year's election, say so. If it means losing coverage, say so loudly and more than once.

15 days out: close it

• Chase non-responders individually, not by group email
• Collect dependent verification where you require it
• Confirm waivers are documented, which matters for ACA reporting
• Review elections for obvious errors, such as a single employee on a family tier

After enrollment: verify

• Reconcile the first payroll deduction register against the carrier invoice, line by line
• Confirm the carrier received every enrollment and every termination
• Check that ID cards arrived, and chase the ones that did not before someone needs care
• File the documentation you will need for ACA reporting in January
• Write down what went wrong this year while you still remember it

What to have ready next year

Keep a single folder with your renewal letter, current summary of benefits, most recent invoice, enrollment census counts by tier, and your payroll deduction register. Having those four things in one place is worth roughly two weeks of the process.

The short version

Start at 120 days, decide your contribution strategy on purpose, test deductions against the carrier rate sheet before go-live, and communicate in dollars per paycheck rather than percentages per month. Almost every open enrollment failure traces back to starting late.
