HSA: the triple tax break
You need an HSA-qualified high-deductible plan (for 2026, a deductible of at least $1,700 self / $3,400 family, and an out-of-pocket max no higher than $8,500 / $17,000). Contributions through payroll skip income tax and FICA, the money grows tax-free, and withdrawals for medical costs are tax-free. The balance is yours forever, even if you change jobs.
Health FSA: use it or (mostly) lose it
Any plan type can offer an FSA. The full yearly election is available on day one, but unused money is forfeited beyond the carryover or grace period. Elect only what you're confident you'll spend: glasses, prescriptions, copays, dental work.
Can you have both?
Not a regular health FSA plus an HSA. You can pair an HSA with a limited-purpose FSA (dental and vision only), and anyone can use a dependent care FSA for daycare, preschool or summer day camp.
How to choose
- On an HDHP? Prioritize the HSA, ideally up to the limit if cash flow allows.
- On a PPO/HMO with predictable expenses? Elect a health FSA for those amounts.
- Paying for childcare? The $7,500 DCFSA can save $1,500–$2,500+ in taxes.
