You can have only one HSA at a time, but you can move money between accounts or switch providers without losing what you've saved

The IRS rule is straightforward: you cannot hold more than one Health Savings Account in the same calendar year. If you try to open a second one while the first is active, you will trigger an excess contribution penalty of 6% per year on the money in the second account, plus income tax on the earnings. The rule applies even if the accounts are at different banks or with different employers.

What you can do is close one account and open another, or consolidate multiple accounts into a single one. You can also change HSA providers without closing the account itself. The money you have already saved stays yours and keeps growing tax-free, regardless of which provider holds it.

Key Takeaways

  • Federal law limits you to one active HSA per calendar year, and opening a second one triggers a 6% annual penalty on excess contributions.
  • You can move money from one HSA to another through a trustee-to-trustee transfer without closing either account or paying taxes.
  • If you have multiple old HSAs from previous jobs, you can combine them into one account at any time.
  • Switching HSA providers does not require you to close your account; you can keep the same account number and move the funds.
  • If you accidentally open two HSAs in the same year, you must close one and file Form 8889 to report the excess contribution to avoid penalties.

Why the one-account limit exists

The IRS treats an HSA like a retirement account in this respect: the contribution limit is per person, not per account. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. If you could open multiple accounts, you could contribute that amount to each one and multiply your tax-free savings. The one-account rule closes that loophole.

The rule applies to the calendar year, not to your employment. If you leave a job in June and your employer closes your HSA, you can open a new one with a different provider in July without penalty. What you cannot do is have both accounts open and funded at the same time.

Moving money between HSAs without penalty

If you want to consolidate accounts or switch to a provider with lower fees, use a trustee-to-trustee transfer. You contact the new HSA provider and give them the account number and routing information of your old one. The two institutions handle the transfer directly; the money never touches your hands. No taxes are owed, no penalties explore, and the transfer typically takes one to two weeks.

Do not withdraw the money yourself and deposit it into a new account. That counts as a distribution, which is taxable unless you use it for may have access to medical expenses. A trustee-to-trustee transfer is the only way to move the full balance tax-free.

You can do a trustee-to-trustee transfer as many times as you want. Some people move their HSA every few years to chase lower fees or better investment options. Each transfer is treated as a continuation of the same account for contribution-limit purposes.

What happens if you accidentally open two HSAs

If you discover you have two active HSAs in the same year, close one when ready. The IRS will not automatically penalize you if you catch the error and fix it before filing your tax return. You will need to file Form 8889 (Health Savings Accounts) and report the excess contribution. The penalty is 6% of the excess amount for each year it remains in the account.

Example: You open an HSA in January and contribute $2,000. In September, you open a second one and contribute $1,500. Your annual limit is $4,150, so the excess is $350. If you close the second account before year-end and report it on Form 8889, you owe 6% of $350 ($21) in penalties plus income tax on any earnings in that account. If you leave both accounts open, you owe 6% per year until you close one.

The key is to report it yourself. The IRS learns about duplicate accounts through employer filings and 1099-SA forms (which HSA providers send to the IRS). If the IRS catches it first, penalties and interest compound.

HSAs from old jobs and what to do with them

You can leave an HSA with a former employer's plan indefinitely. The account continues to grow tax-free, and you can still withdraw money for may have access to medical expenses. However, many employer plans charge higher fees or offer limited investment choices once you leave the company.

You have the option to roll the old account into a new HSA at a bank or brokerage of your choice through a trustee-to-trustee transfer. This does not count as a second account; it is a consolidation. After the transfer, you have one HSA with one provider, and the money from your old job is now part of it.

If you have three old HSAs from three different jobs, you can consolidate all three into one new account in a single year. Each transfer is separate, but the result is one active account. This is often worth doing because it simplifies record-keeping and lets you choose a provider with lower fees.

HSA ownership and what changes when you switch jobs

Your HSA is yours, not your employer's. When you leave a job, the account stays with you. Your employer cannot close it or take the money. What sometimes changes is the provider: some employers use a specific bank or plan administrator, and you may need to move the account if that provider does not allow former employees to keep accounts open.

If your employer's HSA plan requires you to move the account, you have 30 to 60 days (depending on the plan) to initiate a trustee-to-trustee transfer to a new provider. Do this before the important date, because after that window closes, you may only be able to withdraw the money, which triggers taxes and penalties if you do not use it for medical expenses.

Check your plan documents or call your HSA provider to find out whether you can keep the account open after leaving the job. If not, start the transfer process as soon as you know you are leaving.

Frequently Asked Questions

Can I have an HSA and an FSA at the same time?

No. An HSA and a Flexible Spending Account (FSA) cannot be active in the same year, with one exception: a limited-purpose FSA that only covers dental and vision expenses. If you have a general FSA through your employer, you cannot open an HSA until that FSA is closed or the plan year ends.

What if my spouse has an HSA—can I open one too?

Yes. Each person can have one HSA. If you are married and both have individual health insurance plans, you can each have your own HSA. If you are both on a family plan, only one of you can have the HSA (the one whose name is on the account), but the money can be used for medical expenses for any family member.

If I close an HSA, can I open a new one later in the same year?

Yes. The rule is one active account per year, not one account total. If you close an HSA in March, you can open a new one in April. Your contribution limit for the year is still the same ($4,150 or $8,300), so you would need to track contributions across both accounts to avoid exceeding it.

Do I lose my HSA money if I change jobs?

No. The money in your HSA is always yours. When you change jobs, the account may need to move to a new provider, but the balance transfers with it. You never lose access to the money or the tax-free growth, as long as you use it for may have access to medical expenses.

What if I have an old HSA I forgot about—do I need to close it?

Not unless you have opened a new HSA in the same calendar year. If your old account is from a previous year and you have not contributed to it recently, it can stay open. You can still withdraw money from it for medical expenses. If you want to consolidate it with a current HSA, you can do a trustee-to-trustee transfer at any time.
