Frequently Asked Questions
Who can contribute to an HSA?
You must be enrolled in a High Deductible Health Plan (HDHP), not
covered by other non-HDHP insurance, not enrolled in Medicare, and not claimed as a
dependent.
What qualifies as an HDHP?
For 2026: minimum deductible of $1,650 (self) or $3,300 (family),
with maximum out-of-pocket of $8,300 (self) or $16,600 (family).
What can I use HSA funds for?
Qualified medical expenses including doctor visits, prescriptions,
dental, vision, and many others. After 65, funds can be used for anything (taxed as income
if non-medical).
Do HSA funds expire?
No! Unlike FSAs, HSA funds roll over indefinitely. You own the
account and keep it even if you change jobs or health plans.
Payroll vs direct contribution?
Payroll deduction saves FICA taxes (7.65%). Direct contributions
only save income tax. Use payroll deduction if available for maximum savings.
Can I invest my HSA?
Yes! Most HSA providers offer investment options. This can
significantly grow your balance over time, especially if you pay current medical expenses
out-of-pocket.
