Navigating Open Enrollment

Why This Matters

Once a year, most employers open a short window, often two to three weeks, during which employees can change their health insurance, adjust retirement contributions, re-elect FSA amounts, and update other benefits. Outside that window, most changes aren't allowed at all unless a qualifying life event occurs.

Because the window is short and often arrives during a busy season, it's easy to let it pass with minimal attention, clicking through the same elections as last year without checking whether they still fit your life.

Open enrollment isn't just an annual chore. It's the one scheduled opportunity you have to deliberately reset your benefits to match your current situation, rather than defaulting to whatever you chose in the past.

Core Principle

Open enrollment is the one time each year your benefit elections are yours to change on purpose, miss it, and you're often locked in for twelve months.

What Open Enrollment Actually Is

Open enrollment is a defined period, set by your employer, during which you can enroll in, change, or drop workplace benefits for the coming plan year. Most employers hold it in the fall for a January 1 plan year start, but the exact timing varies by company.

This is different from new-hire enrollment, which happens once, shortly after you're hired, and typically gives you 30 days to make your initial elections. Open enrollment is the recurring, annual version of that same decision point, available to everyone at the company at the same time.

What Automatically Carries Over vs. What Needs Action

Not everything requires action during open enrollment, but assuming everything carries over automatically is a common and costly mistake.

• Health insurance plan selection often carries over automatically if you take no action, though the plan's cost or coverage details may have changed for the new year
• FSA elections almost always require a fresh election every year, unlike some other benefits, FSAs typically do not roll over automatically, even if you want the same amount as last year
• HSA contribution elections may carry over depending on your employer's system, but it's worth confirming, especially if the annual contribution limit changed
• Retirement plan contribution rates usually continue unless you actively change them, since they aren't tied to the annual enrollment cycle the same way insurance is
• Voluntary benefits, like supplemental life or disability insurance, vary by employer, some carry over, some require re-election

Checking your specific employer's rules for each benefit takes a few minutes and prevents the surprise of losing an FSA election you assumed was still active.

Using Your Benefits Checkup During This Window

If you've built the benefits checkup habit described in an earlier lesson, open enrollment is exactly when that habit pays off. Rather than starting from scratch, you're refreshing a review you've already done at least once.

• Pull up your current elections and compare them against what's changed in your life this year, a new dependent, a change in health needs, a shift in income
• Revisit your HSA or FSA balance and spending pattern from the past year to calibrate next year's election
• Check whether your retirement contribution rate still matches your goals, especially after a raise
• Confirm your beneficiary designations are still accurate before the new plan year begins

Doing this two weeks before the enrollment window closes, rather than the night before, gives you time to ask HR questions instead of guessing under a deadline.

Reading Plan Changes Before You Decide

Employers frequently adjust their benefit offerings from year to year, premiums change, networks change, and sometimes entirely new plan options are introduced. Re-electing the same plan out of habit, without reading what changed, can mean missing a better fit or an unexpected cost increase.

• Compare this year's premium and deductible for your current plan against last year's, not just against other plans offered this year
• Check whether your regular doctors and pharmacies are still in-network under any plan you're considering
• Read the Summary of Benefits and Coverage, a standardized document every plan is required to provide, to compare plans on equal terms
• Ask HR directly about anything that changed and isn't clearly explained in the enrollment materials

Qualifying Life Events: Enrollment Outside the Window

Open enrollment isn't the only opportunity to make changes. A qualifying life event (QLE), such as marriage, divorce, the birth or adoption of a child, or a loss of other coverage, opens a special enrollment window outside the normal annual period.

Most plans give you a limited window, commonly around 30 days from the event, to report a QLE and make related changes. Missing that window generally means waiting until the next open enrollment period, so acting promptly matters.

A Realistic Example

Sam has been at the same job for three years and has selected the same health plan every open enrollment, mostly out of habit. This year, during a two-week open enrollment window in November, Sam sets a calendar reminder two weeks before the deadline to do a proper review.

Sam checks the enrollment materials and notices the employer added a new HSA-eligible plan option with a lower premium, $62 per paycheck versus $95 for the current plan, paired with a higher deductible. Sam also reviews last year's FSA spending, which came in at $380 out of a $500 election, and decides to lower next year's FSA amount to $400 to better match actual spending.

After comparing the new HSA-eligible plan's total costs against a typical year of healthcare use, Sam decides to switch. The decision point: Sam actively re-elects the new plan and submits an FSA election of $400, rather than letting the system default to last year's choices, completing the whole review in about 40 minutes, spread across two sittings during the two-week window.
