Benefits Open Enrollment Prep

Tuesday, September 1, 2026

Typical start of open enrollment preparation. Review plan changes, update materials, and schedule employee communications.

Who must comply

Any employer that sponsors group health or other benefits with an annual enrollment window — most commonly for a January 1 plan-year start.

Background

Open enrollment isn't a single statutory deadline but a season — most employers run it in the fall so elections take effect January 1. Several ACA and ERISA notices must be delivered at or before enrollment.

How to make the most of it

  • Finalize plan designs, rates, and carrier changes before communications go out.
  • Refresh required notices (SBCs, CHIP, Part D, WHCRA) and the enrollment guide.
  • Build a communication calendar with reminders for managers and employees.
  • Schedule info sessions and make sure the enrollment system is tested and ready.

Frequently asked questions

When should open enrollment prep start?

+

Most HR teams begin in late summer or early fall — around September — so plan decisions, notices, and communications are ready before a fall enrollment window and a January 1 effective date.
