Assumptions

  • Requires an HSA-eligible high-deductible health plan. Withdrawals for qualified medical expenses are tax-free; after 65, other withdrawals are taxed like a traditional IRA.
  • California and New Jersey tax HSA contributions at the state level — leave state tax out of the rate there.

Frequently asked questions

What are the 2026 HSA contribution limits?+

$4,400 for self-only coverage and $8,750 for family coverage, plus a $1,000 catch-up if you're 55 or older. Employer contributions count toward the limit.

Why is an HSA called triple tax-advantaged?+

Contributions are tax-deductible (and skip Social Security and Medicare taxes through payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free.

Who can contribute to an HSA?+

You must be covered by an HSA-eligible high-deductible health plan, have no other disqualifying coverage, not be enrolled in Medicare and not be claimed as someone's dependent.

What happens to my HSA after 65?+

It keeps working for medical expenses tax-free. For anything else, withdrawals after 65 are taxed as income — like a traditional IRA — with no penalty.
