The average American employee leaves $1,000–$3,000 in annual workplace benefits unused. Open enrollment is the once-a-year window to capture all of it — and most people spend less than 20 minutes on decisions worth thousands of dollars.
Benefits most employees underuse
FSA (Flexible Spending Account)
$3,300 in 2026 for healthcare FSA. Pre-tax money for predictable healthcare expenses (glasses, dental, prescriptions, copays). At 22% bracket: $3,300 FSA saves $726 in taxes. The catch: use-it-or-lose-it for most employers (some allow $640 rollover). Only elect FSA if you have predictable healthcare spending to cover it.
Dependent Care FSA
$5,000 per household pre-tax for childcare, after-school care, elder care. At 22% bracket: $1,100 in tax savings. If you're paying $15,000/year in daycare: this is a mandatory election.
Commuter Benefits
$315/month in 2026 for transit and $315/month for parking — both pre-tax. A commuter spending $200/month on transit + $200/month on parking: saves $960/year in taxes at 24% bracket.
Employee Stock Purchase Plan (ESPP)
Most ESPPs offer a 15% discount on company stock at purchase. That's a guaranteed 15%+ return on each purchase. Even if you immediately sell every share at purchase: 15% risk-free return with a 2-year cap period. Contribute the maximum if offered and if your emergency fund is intact.
Tuition Reimbursement
The IRS allows $5,250/year in employer-paid education tax-free. Many employers offer this and few employees use it. A master's degree or professional certification paid by your employer: potentially $30,000–$60,000 in education at no cost to you.
