Frequently Asked Questions
What makes the HSA 'Triple Tax Advantaged'?
1. Contributions are 100% tax-deductible (and exempt from FICA if payroll deducted). 2. Investment growth is tax-free. 3. Withdrawals for qualified medical expenses are completely tax-free at any age.
What is the difference between HSA and FSA rollover rules?
HSA funds never expire and roll over indefinitely year after year. Healthcare FSAs are 'use-it-or-lose-it' with an IRS maximum rollover cap of roughly $640 into the next year.
Who is eligible to contribute to an HSA?
To qualify for an HSA, you must be enrolled in an eligible High Deductible Health Plan (HDHP) and have no other non-HDHP medical coverage.
Can an HSA be used as a stealth retirement account?
Yes. After age 65, you can withdraw HSA funds for non-medical expenses penalty-free (taxed as ordinary income, identical to a traditional 401k), while medical withdrawals remain 100% tax-free.
