Open enrollment is a deadline, not a project.
The date does not move, the elections have to reach the carriers before it, and almost everything that goes wrong goes wrong in the last four days.
Start from the effective date and count backwards.
An enrollment window is the visible part. Three things have to happen before it opens and one after it closes, and the one after is the step employers skip.
Plan Build and Testing
Rates, contribution structure and eligibility rules loaded and checked against this year’s renewal rather than last year’s file. Tested with real scenarios, not a demo record. Testing the plan build prevents open enrollment errors that would otherwise have to be fixed employee by employee. Turn your renewal date into a calendar with our open enrollment timeline calculator.
Communication
What is changing, in plain words, before the window opens. A change explained inside the window becomes a phone call. Early communication reduces open enrollment calls, because employees arrive already knowing what changed and why. Show employees the full value of their package with our total compensation calculator.
The Window Itself
Long enough to cover a pay cycle and a weekend. Two weeks is typical. One week generates the calls you spend the following month returning. A two-week window keeps open enrollment manageable for employees and for the HR team answering their questions. Our free benefits cost per hour worked calculator shows what benefits add to an hour of pay.
The Gap Before the Effective Date
Reserved for corrections, not for stragglers. This is the step that gets cut when the build runs late, and it is the one that saves the month. A correction window protects the plan effective date. Protect the gap when builds run late. To set a budget from a payroll target, try our free benefits budget target calculator.
Making everyone re-enroll is a choice, not a default.
What Each One Hides and What It Surfaces
Passive enrollment rolls existing elections forward. It is quieter, and it hides things: a dependent who aged out, a plan that no longer exists, a contribution that changed without anyone reading the notice.
Active enrollment forces every employee to make a choice. It surfaces exactly those problems, and it costs you chase-down time on the people who ignore three emails.
The question is not which is easier. It is whether anything material changed this year. A new carrier, a network change or a restructured contribution argues for active. A flat renewal usually does not. Making the call deliberately is worth more than whichever way it lands.
You should be able to see who has finished.
Completion by department and by location. Who opened it and stopped halfway. Which elections are missing a dependent date of birth or a beneficiary, because those are the two fields that hold up a carrier file.
This is the difference between managing an enrollment and finding out afterwards how it went. A spreadsheet kept by hand tells you what was true on Tuesday, which is the same as telling you nothing on Friday.
The week nobody plans for.
Elections go to the carriers, deductions go to payroll, and the two have to agree with each other and with what the employee believes they chose.
Discrepancies are cheap to fix in that week and expensive in February, when they surface as a denied claim and an employee who is certain they enrolled. If your plan renews 1 January, that week falls in the middle of the holidays, which is exactly why it has to be on the calendar rather than left to whoever is still at their desk.
How you know your people chose well.
After the window closes we send you a short election review. It is built from the enrollment record, never from anyone’s medical details, and it answers the question most employers never get answered: did the education work?
Plan Mix
Where employees landed across the plans and tiers, against last year. When nearly everyone picks the richest plan regardless of age or family size, people are choosing by default. Plan mix shows whether employees chose deliberately. Defaults hide poor choices.
Movement
Who changed plans and who simply rolled forward, so you can see whether a plan or contribution change actually reached anyone. Movement data shows whether changes reached employees, and whether a new plan or contribution actually changed any choices. Look at who moved.
HSA Uptake
How many employees in the high-deductible plan opened and funded the HSA that makes that plan work. HSA uptake shows whether the high-deductible plan works as designed, because an unfunded HSA leaves employees exposed to the deductible. Check funding as well as opening.
What to look for, and why we treat enrollment education as an investment rather than a cost, is in our guide to employees picking the right health plan.
Quick Answers.
Short answers to what employers ask most. This is general information, not legal or tax advice.
When should we start planning open enrollment?
Start well before the window opens, with plan build, testing and communication done first. The window itself is the shortest part of the project.
How long should the open enrollment window be?
Long enough to cover a pay cycle and a weekend. Two weeks is typical, and a one-week window tends to generate calls you spend the following month returning.
What goes wrong most often at open enrollment?
Late rate or eligibility loads, unclear communication and elections that reach the carrier after the deadline. Testing the build early catches most of them.
Do you manage open enrollment for us?
Yes. Our team builds and tests the enrollment, helps communicate the changes and reconciles elections with the carriers before the effective date.
