Open enrollment is one of the only times all year that plan decisions, employee communication, compliance deadlines and payroll updates all land in the same few weeks. For a business with a dedicated benefits team, that is manageable. For a business where the owner is also running enrollment between everything else on their plate, it is where things get missed — a notice that never went out, a deadline that slipped, an employee who defaulted into a plan nobody actually explained to them.
None of that has to happen. Here is the full checklist, broken into the order it actually comes up.
60–90 days out: benchmark before you renew
The single most expensive habit in small-business benefits is auto-renewing without shopping. Markets move, and funding options that were not available for your size a few years ago are often on the table now.
- Pull your current plan's performance. Utilization, the renewal number the carrier is proposing, and whether participation still clears the carrier's minimum.
- Get a second design quoted against the same census. At minimum, compare your current plan to one alternate structure — not just a different carrier at the same design.
- Run the numbers on MightyWELL Health before you assume a traditional renewal is the only path. For a generally healthy group it commonly comes in 40–60% lower than a traditional plan, and it is worth modeling even if you end up staying with what you have.
- Check voluntary and ancillary pricing too. Dental, vision, accident and hospital indemnity should get the same once-a-year look, not just medical.
- Confirm the numbers with a short employee survey if you are not sure what people actually want changed. It takes ten minutes to send and tells you where to spend your communication effort.
45–60 days out: decide the design and the budget
- Set a per-employee-per-month number the business can sustain in a slow year, not a good one. Let that number drive the plan design, not the other way around.
- Choose a defined-contribution amount rather than a percentage of premium, if you are not already. A fixed dollar amount caps what a double-digit renewal costs the company.
- Land on two or three medical options, not five. More choice reads as generosity and produces confusion, longer meetings, and employees defaulting to whatever a coworker picked.
- Finalize eligibility rules — waiting periods, hours thresholds, and which classes of employees (full-time, part-time, by location) get which contribution.
30–45 days out: prep the compliance paperwork
This is far lighter under 50 employees than most owners fear, but the pieces that do apply are not optional, and they need to go out with the rest of the enrollment packet, not scrambled together afterward.
- Summary Plan Description and Summary of Benefits and Coverage for any plan being offered or changed.
- Section 125 plan document if premiums are deducted pre-tax through payroll.
- Required notices — HIPAA privacy notice, CHIPRA notice where it applies, Women's Health and Cancer Rights Act notice, and new-hire notices for anyone who has joined since the last cycle.
- COBRA administration confirmed if you are at or near 20 employees, and check state continuation rules even below that.
- Coordinate with your payroll provider so deduction changes are ready to load the moment elections close — this is the step that gets forgotten most often.
2–4 weeks out: communicate, more than once
More than half of employees say they rely mostly on what their employer hands them to make these decisions. A single all-staff email is not a communication plan.
- Set firm enrollment dates and announce them on at least two channels — email plus a physical posting or a team meeting mention.
- Send a side-by-side plan comparison covering premium, deductible, out-of-pocket maximum and network, in plain language, not a carrier brochure.
- Schedule a live education meeting or Q&A, in person or virtual, so people have somewhere to bring questions before they have to decide anything. This is the single highest-leverage thing you can do — employees who understand their benefits use them and value them.
- Send a reminder the week before the window opens, and another partway through.
During the window: run enrollment
- Send reminders as the deadline approaches, including one the day before it closes.
- Check submitted forms for completeness as they come in rather than all at once at the end — a missing signature caught on day two is a two-minute fix, caught on the last day it is a scramble.
- Keep a real person answering questions for the duration, whether that is you, an office manager, or a broker who will actually pick up the phone.
After the window closes
- Submit enrollment data to carriers promptly — most have a hard cutoff for the effective date you are targeting.
- Update payroll systems with final deduction amounts before the first affected pay period.
- Confirm ID cards and welcome materials reach employees before the effective date, not after.
- Send a short post-enrollment survey. What went well, what was confusing, what to fix before next year — five minutes now saves real time on the next cycle.
