You can have only one HSA at a time, and the IRS enforces this rule strictly

The Internal Revenue Service allows you to own one HSA per person per year. If you open a second HSA while the first one is still active, you have violated the rule, and both accounts are considered out of compliance. The IRS does not distinguish between accounts at different banks or with different HSA administrators — if two accounts are in your name and both are active in the same calendar year, you are over the limit.

This rule exists because HSAs are designed to work alongside a specific type of health insurance plan (a high-deductible health plan, or HDHP). One HSA per person per year prevents people from accumulating multiple tax-advantaged accounts and exceeding the annual contribution limit, which varies by whether you have individual or family coverage.

If you already have an HSA and you want to move your money to a different bank or HSA provider, you do not open a new account — you transfer the existing one. That transfer does not count as a second account and does not trigger the one-per-year rule.

Key Takeaways

  • The IRS limits you to one HSA per calendar year, regardless of how many banks or providers you use.
  • Opening a second HSA while the first is active makes both accounts non-compliant and can result in tax penalties.
  • Moving your HSA to a different provider is a transfer, not a new account, and does not violate the one-per-year rule.
  • If you close an HSA before the end of the year, you can open a new one in the same year, but contribution limits still apply to the total across both.
  • Married couples can each have one HSA, so a household can have two accounts if both spouses have HDHP coverage.

What happens if you accidentally open two HSAs

If you discover you have two active HSAs in the same year, the IRS treats this as an excess contribution. You must close one of the accounts and withdraw the excess funds. The funds you withdraw are subject to income tax, and you also owe a 6 percent excise tax on the excess amount for each year it remains in the account.

The best way to fix this is to contact both HSA providers immediately and ask which account to close. The provider you keep should be able to help you understand the tax consequences. You will need to report the excess contribution on your tax return (Form 8889) when you file, and you may want to consult a tax professional to make sure you handle it correctly and avoid additional penalties.

The IRS does not automatically catch duplicate HSAs — it relies on the HSA providers to report contributions to the IRS. However, when you file your taxes, the IRS will see multiple Form 5498-SA filings (the form HSA providers use to report contributions) and will flag the discrepancy. It is better to fix it yourself than to wait for the IRS to contact you.

Transferring an HSA to a new provider without opening a second account

If you want to move your HSA to a different bank or provider — because of lower fees, better investment options, or simply better customer service — you do this through a trustee-to-trustee transfer. You contact your new HSA provider and ask them to initiate the transfer. They will request the funds directly from your old provider, and the money moves without ever passing through your hands.

A trustee-to-trustee transfer does not count as a withdrawal, does not trigger taxes, and does not create a second account. From the IRS perspective, you still have one HSA — it just has a new custodian. The transfer can take one to four weeks, depending on how quickly the old provider processes the request.

Do not withdraw the money yourself and deposit it into a new HSA. If you do, the IRS may treat it as a distribution from the old account and a contribution to a new account, which could trigger the excess contribution rules. Always ask the new provider to handle the transfer directly.

Married couples and HSA accounts

If you are married and both you and your spouse have individual HDHP coverage (not family coverage), you can each have your own HSA. That means a married household can have two active HSAs at the same time — one in each person's name. Each account has its own contribution limit and its own investment options.

If you have family HDHP coverage that covers both of you, only one HSA can be opened and funded. The account can be in either spouse's name, but there is only one account for the household. If you already have an individual HSA and then switch to family coverage, you must close the individual account or convert it to a different type of savings account (which may trigger tax consequences).

When you file taxes as a married couple, each HSA is reported separately on Form 8889. Make sure both spouses understand which account belongs to whom and who is responsible for tracking contributions and withdrawals.

Changing jobs or losing HDHP coverage mid-year

If you close your HSA because you no longer have HDHP coverage, you can open a new HSA later in the same year if you regain HDHP coverage. However, your total contributions across both accounts for that year cannot exceed the annual limit. For example, if you contributed $2,000 to your first HSA before losing coverage, and you regain coverage later and open a second HSA, you can contribute only $1,850 more (assuming the 2024 individual limit of $3,850) before hitting the annual cap.

You must report both accounts on your tax return and calculate the total contributions yourself. The HSA providers will not do this for you. If you exceed the limit, you owe the 6 percent excise tax on the overage for each year it sits in the account.

To avoid confusion, close the first account completely before opening a second one. Get written confirmation from the old provider that the account is closed and that all funds have been distributed or transferred. Keep this documentation for your tax records.

HSA rollovers and the one-account rule

An HSA rollover is different from a transfer. A rollover happens when you withdraw money from one HSA and deposit it into another HSA within 60 days. The IRS allows one rollover per HSA per 12-month period. However, a rollover does not exempt you from the one-HSA-per-year rule — you still cannot have two active HSAs at the same time.

If you perform a rollover, the old account should be closed as part of the process. If it remains open and active, you are in violation. Always confirm with both providers that the old account is closed before the 60-day rollover window ends.

Rollovers are less common than transfers because transfers are simpler and do not require you to handle the money yourself. Unless you have a specific reason to do a rollover (such as moving money between accounts at the same provider), a trustee-to-trustee transfer is the safer option.

Frequently Asked Questions

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

No. If you have an FSA (Flexible Spending Account), you cannot have an HSA in the same year. The IRS treats these as competing accounts because both are tax-advantaged health savings vehicles. You must choose one or the other. Some employers offer both, but you can only enroll in one during open enrollment.

What if I inherit an HSA from a spouse?

If your spouse dies and leaves you their HSA, you can treat it as your own HSA. This is the only exception to the one-HSA rule — a surviving spouse can combine the inherited HSA with their own without penalty. You will need to contact the HSA provider and provide a death certificate to change the account ownership.

Do I need to close my old HSA before opening a new one at a different provider?

No. You should initiate a trustee-to-trustee transfer instead, which moves the money without closing the account first. The old provider will close the account once the transfer is complete. If you close it manually before transferring, you may trigger a taxable distribution.

What if I have two HSAs and do not realize it until tax time?

Contact both providers immediately and close one account. Withdraw the excess contributions and report the overage on Form 8889 when you file your taxes. You will owe income tax and a 6 percent excise tax on the excess. A tax professional can help you calculate the exact amount and file an amended return if needed.

Can I have an HSA in one state and another HSA in a different state?

No. The one-HSA-per-year rule is federal and applies regardless of where you live or where the HSA provider is located. State residency does not create an exception to the IRS limit.
