How to Access an Old HSA Account From a Previous Employer

To access an old HSA from a previous employer, you need to identify which financial institution holds the account, prove your identity to that custodian, and reset your login. Old tax forms are the fastest way to find the custodian’s name, and if the balance has already been turned over to the state as unclaimed property, a national database will point you to it. The money is still yours: HSA balances belong to you permanently and never expire, regardless of whether you still work for the employer who set up the account.¹

Move quickly. Dormant HSAs quietly accumulate monthly fees, and after a few years of inactivity the custodian is legally required to escheat the balance to your state. The sooner you track the account down, the more of it you keep.

Finding the Custodian That Holds Your Account

Start with old tax paperwork. On the W-2 from the employer who offered the HSA, look at Box 12 for an entry labeled “Code W.” That code confirms HSA contributions were made through payroll that year, which tells you the account existed and pins down the time frame.² The W-2 alone won’t name the custodian.

Two IRS forms will. Form 1099-SA reports distributions from the account, and Form 5498-SA reports contributions and the year-end balance. Both are required to display the financial custodian’s name and address, so if you can find either one, you have the institution’s identity.³ Search old email for electronic copies. If nothing turns up, you can request prior-year tax transcripts from the IRS.

No tax documents? Call the Human Resources department at your former employer. HR can generally identify which bank or benefits administrator ran the HSA program during the years you worked there. Give them the specific calendar year, since employers occasionally switch custodians.

If the Custodian No Longer Exists

HSA custodians get acquired, merged, and rebranded often. If you remember your old provider but it seems to have vanished, the account most likely transferred to a successor institution. A web search for the old name plus “acquired by” or “merged with” is usually the quickest path to the answer. The FDIC’s BankFind tool also lets you look up any FDIC-insured bank and review its merger history.⁴

What You Need to Prove You Own the Account

Federal law requires custodians to verify the identity of every account holder, and that requirement doesn’t relax because the account is old. At a minimum, have your Social Security number ready, since that’s the primary identifier linking you to the account.⁵ Also gather your full legal name as it appeared on the account, your date of birth, and the mailing address on file when the account was last active.

Knowing which employer sponsored the plan helps the custodian narrow their records, especially at large institutions administering accounts for hundreds of companies. Any old account numbers, contribution confirmations, or HSA debit card numbers should go on the same list. Having this ready is often the difference between one phone call and weeks of follow-up.

Expect additional documentation if your name or address has changed. A current driver’s license, Social Security card, utility bill at your new address, or marriage certificate covering a name change will usually satisfy the custodian.

Regaining Login Access

Try the custodian’s website first. Most offer a “forgot password” or account recovery flow that uses your email address or Social Security number to reset credentials. If the site doesn’t recognize you, the usual cause is an outdated email on file or a platform migration after an acquisition. That doesn’t mean the account is gone.

Call member services next. A representative will walk you through identity verification, and once you’re confirmed as the account holder, they’ll issue new credentials and update your contact information. If the account was flagged as dormant or restricted for inactivity, you may need to submit a written request or complete an identity verification form before the hold is lifted. Federal anti-money-laundering rules require custodians to re-verify identity in these situations, and if verification fails the custodian can close the account and return the funds to you or your employer.⁶

Fees Draining a Dormant Balance

While an old HSA sits untouched, the custodian may be charging monthly maintenance fees that slowly cut into the balance. A 2024 CFPB review of the largest HSA trustees found monthly maintenance fees ranging from zero to $4 depending on the custodian and how the account was opened.⁷ At the top of that range, $48 a year is disappearing from an account you may not even remember exists.

The fees usually get worse after you leave the employer. Many companies pay the maintenance fee for active employees, but once you separate, the custodian starts billing you directly. The CFPB found that consumers are frequently blindsided by that switch, sometimes discovering the charges only after months of deductions.⁷ Paper statement fees of $1 to $1.50 per cycle add to the drain. On a small balance, a couple of years of neglect can wipe out the account entirely.

If you plan to close the account or move the funds, budget for that too. Account closure fees of $25 and outbound transfer fees of $20 are common at major custodians, and both come out of the HSA balance itself.⁷ On a very small remaining balance, spending it down on qualified medical expenses may leave you with more than transferring it does.

If the Money Has Already Been Turned Over to the State

Sit dormant long enough and the custodian is legally required to transfer the balance to the state where you last lived, through a process called escheatment. Timelines vary. The Revised Uniform Unclaimed Property Act sets a three-year dormancy period for health savings accounts, but not every state has adopted it, and actual timelines run from roughly one to five years depending on the jurisdiction. Once escheatment happens, the custodian no longer holds your money and can’t help recover it.

Escheated funds don’t disappear. States hold them indefinitely, and most do not charge fees or reduce the balance. To search, go to MissingMoney.com, the free national database endorsed by the National Association of Unclaimed Property Administrators.⁸ Enter your full name and any previous addresses. The site queries participating state databases and shows matches if your funds are being held.⁹

When you find a match, file a claim directly with the state treasurer or comptroller’s office holding the funds. Claims typically require a copy of your driver’s license or other government-issued ID plus documentation tying you to the original account, such as an old tax form or a statement from the former custodian. Processing runs from a few weeks to several months depending on the state, and you’ll receive the money by check or electronic transfer once the claim is approved.

One thing to know before withdrawing: recovering the money doesn’t trigger any tax. But if you take funds out for non-medical purposes before age 65, you’ll owe income tax plus a 20% penalty on the distribution.¹⁰ Using the money for qualified medical expenses stays fully tax-free, and after 65 the 20% penalty disappears.¹

Consolidate So You Don’t Lose Track Again

Once you have the old account back, moving it into a single active HSA eliminates the risk of losing it a second time and usually reduces total fees. The safer way is a direct trustee-to-trustee transfer: your new custodian pulls the funds from the old one, the money never passes through your hands, there’s no limit on how often you can do it, and nothing goes on your tax return.¹¹ The old custodian may charge an outbound transfer fee, and any invested balances are typically sold before the transfer unless both custodians support an in-kind move.

A 60-day rollover, where you withdraw the funds and redeposit them into another HSA yourself, is also allowed but limited to once every 12 months across all your HSAs.¹⁰ Miss the 60-day window and the IRS treats the whole amount as a taxable distribution, with the 20% penalty on top if you’re under 65. For most people recovering an old account, the direct transfer is the safer choice.
