Open Enrollment

The annual window during which employees can enroll in, change, or drop employer-sponsored benefits like health insurance, dental, vision, and FSAs.

Open enrollment is the designated period each year — typically 2–4 weeks in the fall — when employees can make changes to their benefits elections for the following plan year. Outside of open enrollment, you generally cannot change your health insurance, dental, vision, or FSA elections unless you experience a qualifying life event such as marriage, divorce, birth of a child, or loss of other coverage. Open enrollment is your once-a-year opportunity to review current benefits, compare plan options, and make adjustments.

Open enrollment is easy to miss or rush through, but the decisions made during this window have a full year of financial consequences. Key decisions include choosing between health insurance plan types (HMO, PPO, or HDHP), setting FSA or HSA contribution amounts, electing or waiving dental and vision, and selecting supplemental benefits like additional life insurance or disability coverage. The most common mistake is defaulting to last year's elections without reviewing whether your needs or the available plan options have changed.

The decision between an HDHP paired with an HSA and a traditional PPO or HMO is one of the most consequential open enrollment choices for most employees. A High Deductible Health Plan has lower monthly premiums but requires meeting a higher deductible before coverage begins. Paired with an HSA, the HDHP allows pre-tax contributions that cover the deductible and roll over indefinitely — unlike FSA funds. For employees who are generally healthy, rarely use medical services, and have the liquidity to absorb the deductible in a bad year, the HDHP/HSA combination is often financially superior to a PPO — the premium savings plus triple-tax HSA advantages frequently outpace the higher deductible exposure.

A qualifying life event outside of open enrollment opens a special enrollment period, but the window is narrow and strictly enforced. Marriage, divorce, birth of a child, adoption, and loss of other coverage all trigger a 30-day window to make benefits changes. What many employees do not know is that changes must be consistent with the triggering event: getting married lets you add your spouse to health coverage, but you cannot use that event as an opportunity to switch health plan types for unrelated reasons. Missing the 30-day window typically means waiting until the next open enrollment — no exceptions.
