Updated August 3, 2026. Quick answer: the HSA is yours, not your employer’s. Leaving the job does not affect the money at all. What often changes is the fees — employers frequently subsidise account fees for current staff and stop when you leave — and you can move it, as often as you like, by trustee-to-trustee transfer.
It is portable, and the IRS says so plainly
An HSA is “portable.” It stays with you if you change employers or leave the work force. … [Rollovers section:] You must roll over the amount within 60 days after the date of receipt. You can make only one rollover contribution to an HSA during a 1-year period. Note: If you instruct the trustee of your HSA to transfer funds directly to the trustee of another of your HSAs, the transfer isn’t considered a rollover. There is no limit on the number of these transfers.
— IRS Publication 969 (2025 rev.), “Qualifying for an HSA Contribution” and “Rollovers” sections; see also IRC 223(d)(1) (HSA established for benefit of an individual) and Notice 2004-50 Q&A-56
Two distinct mechanisms, and confusing them causes real problems:
| Trustee-to-trustee transfer | 60-day rollover | |
|---|---|---|
| Who touches the money | The custodians, directly | You do |
| How often | No limit | Once in a 1-year period |
| Deadline risk | None | 60 days, and missing it is costly |
Use the transfer. It is unlimited, there is no clock, and the money never passes through your hands. The rollover exists for cases where a transfer is not available, and its one-per-year limit is a trap for anyone consolidating several old accounts.
What to actually check after you leave
- The monthly maintenance fee. Often waived for employees and charged to everyone else. On a small balance it can outrun the interest.
- Whether investing is available and what it costs — some employer accounts require a large cash balance before you may invest at all. Whether to invest it depends on what you can access.
- Whether contributions can continue. They can, if you are still covered by a qualifying high-deductible plan — but they lose the payroll tax advantage once they are not made through an employer.
- The beneficiary designation. It moves with the account only if you set it on the new one. Who inherits an HSA matters a great deal, and a spouse is treated very differently from anyone else.
🔴 Do not apply any of this to a health FSA. An HSA is yours and moves with you; an FSA generally stops covering you on your last day and the balance is usually forfeited. The rules are genuinely opposite, and confusing them is the common and expensive mistake — what happens to your FSA when you are laid off.
Two adjacent HSA questions that catch people in the same year: how the catch-up works when both spouses are eligible — it is not one shared amount — and what to do about an over-contribution, which has a deadline and gets more expensive after it.
One thing not to do
Do not close a small old HSA by cashing it out. A distribution not used for qualified expenses is taxable and, before 65, carries an additional tax. Transferring it costs nothing and keeps the money in the only triple-tax-advantaged account there is — along with its original establishment date, which is the boundary for reimbursing older expenses.
