When open enrollment season rolls around, it’s easy to treat the packet as “the health insurance thing” and move on. Many employees do exactly that—especially if they were happy with last year’s medical plan. But open enrollment materials often include changes that have nothing to do with your core health coverage, and those updates can affect your paycheck, taxes, and financial protection for the entire year.
Even if your employer lets last year’s elections “roll over” automatically, that doesn’t necessarily mean every benefit rolls over the same way, or at the same cost. Some items reset annually, some require active re-enrollment, and some can silently change because the carrier, plan design, or employer contribution changed.
Here are the benefits worth reviewing carefully before you assume everything can stay on autopilot.
Start with what changed (and what didn’t)
Most open enrollment packets include a short “what’s new” section. Don’t skip it. Employers often use it to flag plan changes, contribution changes, new vendors, eligibility updates, or new perks. If your packet doesn’t highlight changes upfront, scan the summary plan descriptions, benefit comparison charts, and payroll deduction tables.
Two key questions to answer early:
1) Will your per-paycheck deductions change? Even if you stay in the same plan, premiums can rise, employer contributions can change, and rate tiers (employee-only, employee+spouse, family) can be adjusted.
2) Are any benefits “active election” benefits? Some benefits require you to re-elect them every year (common with flexible spending accounts), and failing to do so can mean you lose access even if you had it last year.
Flexible Spending Accounts (FSAs): likely not automatic
Health care FSAs and dependent care FSAs are frequently offered through open enrollment, and many employers require an active election each plan year. If you assume it will carry over automatically, you may end up with a $0 election for the year.
What to review:
Contribution limits and your budget. Your needs may have changed (braces, therapy, new prescriptions, child care costs, after-school programs). Recalculate what you realistically plan to spend in the new plan year.
Carryover and grace period rules. FSAs often have “use-it-or-lose-it” features, though many plans offer either a carryover amount or a grace period. The details depend on your employer’s plan design, so verify what applies to you.
Eligible expenses and documentation. Rules can be strict, and administrators can change. Check whether receipts, substantiation, or debit card processes have changed so reimbursements don’t become a headache.
Health Savings Accounts (HSAs): check eligibility and contribution strategy
If you have an HSA, the most important thing is whether you remain eligible. HSAs generally require enrollment in an HSA-qualified high-deductible health plan and the absence of disqualifying coverage. During open enrollment, employers sometimes change plan designs or vendors, and the plan you chose last year may no longer be HSA-qualified (or a new option may be).
Also review:
Employer contributions. Some employers seed HSAs each year, contribute per paycheck, or contribute only if you meet certain wellness requirements. Those terms can change.
Payroll deductions and tax treatment. Contributing through payroll can provide tax advantages. If your payroll system, HSA custodian, or contribution schedule changes, make sure your elections align with your savings goals.
Investment options and fees. If the HSA provider changes, your investment lineup, cash thresholds, or fee structure may change too. Consider whether you need to move balances, update beneficiaries, or adjust investments.
Dental and vision: not just “nice to have”
Dental and vision plans can be easy to overlook because they feel secondary to medical coverage. But changes in premiums, coverage tiers, provider networks, and benefit maximums can make a real difference in out-of-pocket costs.
Look for:
Waiting periods and coverage categories. Some plans have different coverage levels for preventive, basic, and major services. If you anticipate major dental work, plan details matter.
Annual maximums and frequency limits. Vision plans may limit how often you can get exams, lenses, or frames. Dental plans often have annual maximums and may have different rules for certain services.
Network changes. If the carrier changed, your dentist or optometrist might be out-of-network, which can shift costs dramatically.
Life insurance: confirm amounts, costs, and evidence of insurability
Many employers offer basic employer-paid life insurance plus optional employee-paid coverage. This is an area where “set it and forget it” can go wrong because life changes are common: marriage, divorce, a new child, a mortgage, or a shift to a single-income household.
Pay attention to:
Coverage multiples and caps. Optional life insurance is often offered as a multiple of salary up to a maximum. If your salary changed, your coverage might change too—or you may need to re-elect your intended amount.
Age-banded pricing. Premiums can increase as you move into a new age bracket. The packet should show how rates work.
Evidence of insurability (EOI). Increasing coverage may require medical underwriting or a questionnaire, and there can be deadlines. If you wait, you might be stuck at your current amount.
Beneficiaries. Even if the plan doesn’t require new enrollment, open enrollment is a good prompt to confirm your beneficiary designations still match your wishes.
Short-term and long-term disability: your income protection cornerstone
Disability insurance often gets less attention than health insurance, even though it protects your paycheck. If you were unable to work for an extended period, disability coverage can be the difference between stability and a financial spiral.
During open enrollment, review:
Who pays the premium. Some employers pay all or part of the cost; sometimes you pay. This matters because premium source can affect whether benefits are taxed when paid out.
Benefit amount and waiting period. Plans vary in how much income they replace and how long you must wait before benefits begin.
Definition of disability and coverage details. Without getting lost in legalese, look for basics like how disability is defined and what coordination exists with other benefits.
Optional buy-up options. Some employers allow higher coverage levels during open enrollment, occasionally with simplified underwriting if you act within the window.
Accident, hospital indemnity, and critical illness plans: evaluate the value, not the marketing
Supplemental health plans are commonly offered during open enrollment and can come with glossy brochures and simple payroll deductions. These plans can be useful for some households, especially those with limited emergency savings or those who want extra protection against specific events.
But they are not one-size-fits-all. Before you enroll (or continue), check:
What triggers a payout. These plans often pay fixed amounts for specific events or services, not necessarily what you actually spend.
How payouts coordinate with your medical plan. A high-deductible plan may pair differently with supplemental coverage than a low-deductible plan.
Total annual cost. Because premiums are taken in small amounts per paycheck, it’s easy to underestimate yearly spending. Compare the annual premium to the realistic benefit you might receive.
Retirement plan contributions: open enrollment can be your annual reset
Your 401(k), 403(b), or similar workplace retirement plan may not be formally part of open enrollment, but many employers coordinate communications at this time, and it’s a natural moment to review contribution rates.
Items to consider:
Employer match changes. Employers may adjust match formulas or eligibility rules. If yours changed, you may want to update your contribution to capture the full match.
Automatic escalation or auto-enrollment features. If your plan includes automatic increases, confirm whether they’ll occur and whether you want to adjust.
Roth vs. traditional contributions. Some plans allow both. Your tax situation may have changed since last year, making it worth reconsidering the mix.
Commuter, parking, and transit benefits: small adjustments add up
If your employer offers commuter benefits, open enrollment may be when you elect or adjust pre-tax deductions for transit passes, vanpools, or parking. If your work schedule changed (hybrid work, new office location, different commuting frequency), last year’s amount may no longer fit.
Review:
Your actual commuting pattern. Overfunding a commuter account can be inconvenient, while underfunding reduces the potential tax advantage.
Vendor platforms and ordering deadlines. If your employer changed providers, the process for ordering passes or reimbursing costs can change.
Wellness programs and incentives: easy to miss, sometimes valuable
Some employers offer premium discounts, employer HSA contributions, gift cards, or other incentives for completing wellness activities such as biometric screenings, health assessments, or coaching programs. The rules and deadlines can shift each year.
What to do:
Scan for incentive requirements and dates. If you need to complete an activity early in the year to earn a discount, put it on your calendar.
Check whether spouses are included. Some programs extend incentives to covered spouses; others don’t.
Employee Assistance Programs (EAPs) and mental health resources
EAPs can provide short-term counseling, legal consultations, financial coaching resources, and referral services. These benefits may not require enrollment, but open enrollment is when employers tend to change vendors or add services.
Even if you’ve never used an EAP, it’s worth knowing:
How to access it. Save the phone number or portal link somewhere easy to find.
What’s included. Offerings differ. Some include sessions for counseling; some include broader support services.
Perks that affect your budget: legal plans, identity theft, pet insurance, and more
Open enrollment packets often include voluntary benefits that sound optional (and they are), but they can still be financially meaningful depending on your situation. Common examples include legal services plans, identity theft monitoring, and pet insurance.
Rather than defaulting to “no” or “yes,” do a quick cost-benefit check:
Would you buy this on your own? If not, why? If yes, compare the group rate and coverage details to what you could obtain independently.
Are there exclusions or waiting periods? Some plans have limits on pre-existing conditions (for pets), covered legal matters, or reimbursement conditions.
Dependent eligibility and documentation: avoid surprise coverage problems
Employers sometimes update dependent eligibility rules or audit documentation. If you added a spouse or child recently, or if a dependent is approaching an age limit, open enrollment is the time to confirm eligibility and avoid denied claims later.
Also confirm whether your employer requires:
Social Security numbers or proof of relationship. Missing information can delay enrollment or claims processing.
Adult dependent rules. Coverage rules for dependents can vary based on plan and employer policies, so verify what applies to your family.
What “automatic re-enrollment” really means
Automatic continuation is convenient, but it can create blind spots. Common situations where “doing nothing” can lead to an unintended outcome include:
FSAs resetting to zero if you don’t actively elect them.
Premium increases that change your take-home pay without you noticing until the first paycheck of the new plan year.
Plan mapping if a plan is discontinued and employees are moved to a similar plan by default.
Network changes that make your doctors out-of-network even if the plan name looks familiar.
A quick checklist for reviewing your packet in under an hour
If time is tight, focus on a few high-impact steps:
1) Compare per-paycheck costs for anything you currently carry (medical, dental, vision, life, disability, supplemental).
2) Confirm active-election benefits like FSAs and commuter deductions.
3) Verify provider networks for medical, dental, and vision—especially if you have ongoing care.
4) Recheck beneficiaries on life insurance and retirement accounts, particularly after major life events.
5) Match benefits to your next-year plans (planned procedures, a new baby, braces, therapy, higher child care costs, or increased travel).
When to ask HR (and what to ask)
If something in the packet is unclear, asking a few targeted questions can save real money later. Consider asking:
• Did any employer contributions change? (Premiums, HSA funding, match formulas.)
• Are any benefits not eligible for rollover? (FSAs, commuter programs, certain voluntary coverages.)
• Did the provider network change? (Medical, dental, vision.)
• Are there new deadlines? (EOI for life/disability, wellness incentive dates.)
Open enrollment is one of the few times each year you can adjust many workplace benefits without a qualifying life event. A careful review goes beyond picking a medical plan—it’s a chance to protect your income, reduce taxes, and make sure your benefits match the life you’re actually living now, not the one you had last year.
