How Health Savings Account Money Carries Forward Year to Year

HSA funds roll over automatically — there is no "use it or lose it" rule

Money in a health savings account does not disappear at the end of the year. Unlike a flexible spending account (FSA), which has a strict use-it-or-lose-it deadline, an HSA balance carries forward indefinitely. Any funds you do not spend in one year remain in your account and are available to use in future years, with no annual limit on how much can accumulate.

This rollover happens automatically. You do not need to do anything to preserve the balance. As long as your HSA account remains open and you maintain your high-deductible health plan (HDHP) coverage, the money stays there and grows tax-free.

Key Takeaways

• HSA balances roll over to the next year with no deadline — funds never expire as long as the account stays open.
• Unlike FSAs, HSAs have no annual spending requirement and no "use it or lose it" rule.
• If you drop your HDHP coverage, you can no longer contribute to the HSA, but existing funds remain available for may have access to medical expenses.
• The rollover balance grows tax-free and can be invested, making HSAs a long-term savings tool as well as a short-term spending account.
• If you close an HSA account, you forfeit the funds unless you roll them over to another HSA within 60 days.

What happens to your HSA balance when the calendar year ends

On January 1, your HSA balance simply carries forward. There is no reset, no forfeiture, and no action required on your part. The account balance you see on December 31 is the same balance you will see on January 1, minus any transactions that occur between those dates.

This is fundamentally different from an FSA, where you typically lose any unspent money at the end of the plan year (though some plans offer a limited grace period or carryover of up to $610 in 2024). An HSA has no such restriction. You can accumulate funds year after year, decade after decade, if you choose to.

The only requirement is that you remain enrolled in an HDHP. If you switch to a different type of health insurance plan, you can no longer make new contributions to the HSA, but the money already in the account stays there and remains available for may have access to medical expenses.

How the rollover works if you change jobs or health plans

Your HSA is portable — it belongs to you, not to your employer or your health plan. If you change jobs, your HSA balance goes with you. You do not need to do anything; the account is yours to keep.

If you leave your employer's health plan and enroll in a different HDHP (through a new employer, the marketplace, or as an individual plan), you can continue contributing to the same HSA. If you switch to a non-HDHP plan, you stop being able to contribute, but the existing balance remains in the account and can still be used for may have access to medical expenses.

Some people choose to move their HSA to a different financial institution — for example, from their employer's plan administrator to a bank or investment firm that offers HSA accounts. This is called a rollover or transfer. You have 60 days to complete the transfer without tax consequences. If you miss the deadline, the IRS treats the withdrawal as a non-may have access to distribution, which means you owe income tax plus a 20% penalty on the amount transferred.

When you might lose HSA funds and how to prevent it

The main way to lose HSA money is to close the account without rolling it over. If you close your HSA and do not transfer the balance to another HSA within 60 days, you forfeit the funds. The money does not go back to your employer or your health plan — it is simply gone, and you cannot recover it.

Another scenario is withdrawing funds for non-may have access to expenses. If you use HSA money to pay for something that does not count as a may have access to medical expense (such as gym memberships, cosmetic procedures, or over-the-counter items not prescribed by a doctor), you owe income tax on the withdrawal plus a 20% penalty. The funds are spent, the penalty is paid, and the balance is reduced.

To protect your balance, keep your HSA account open even if you change jobs or health plans. If you are switching to a non-HDHP temporarily, you can leave the HSA untouched and use it later when you re-enroll in an HDHP. If you want to move the account to a different provider, initiate the transfer request with your new provider and confirm it is completed within 60 days.

How HSA rollovers interact with investment growth

Many HSA providers allow you to invest the balance in mutual funds, stocks, or other securities, similar to a retirement account. Any investment gains are tax-free, and those gains roll over along with your principal balance. This means an HSA can function as a long-term savings tool, not just a spending account for immediate medical bills.

If you invest your HSA balance and the investments lose value, the lower balance rolls over as well. You do not have to "lock in" losses or take any action — the account simply reflects the current value of your holdings.

Some HSA providers charge fees for investment management or account maintenance. These fees are deducted from your balance and do not affect the rollover itself, but they do reduce the amount that carries forward to the next year. Review your provider's fee schedule to understand what you are paying.

HSA rollover rules if you become ineligible for an HDHP

If you lose may be able to access for an HDHP — for example, because you enroll in Medicare, Medicaid, or a spouse's non-HDHP plan — you can no longer contribute to the HSA. However, the balance you have accumulated remains in the account and can be used for may have access to medical expenses at any time in the future, even after you are no longer enrolled in an HDHP.

Once you are ineligible, you cannot make new contributions, but you can withdraw funds for may have access to medical expenses without penalty. Non-may have access to withdrawals still trigger income tax plus a 20% penalty. The rollover continues indefinitely — the funds do not expire when you lose HDHP may be able to access.

If you become may be able to access for an HDHP again later (for example, if you switch employers or enroll in a marketplace HDHP), you can resume contributions to the same HSA account. The old balance remains, and new contributions are added on top of it.

Frequently Asked Questions

Can I roll over my HSA to a retirement account like an IRA?

No. An HSA can only be rolled over to another HSA. If you withdraw funds and deposit them into an IRA or other retirement account, the withdrawal is treated as a non-may have access to distribution, and you owe income tax plus a 20% penalty on the amount. The HSA and IRA are separate accounts with different rules.

What happens to my HSA if I die?

The HSA becomes part of your estate. If you name a beneficiary on the account, the funds pass to that person. If you do not name a beneficiary, the account goes through probate. The beneficiary or your estate owes income tax on the balance, but there is no 20% penalty. The funds do not disappear — they transfer to whoever inherits the account.

Do I have to spend my HSA balance before I turn 65?

No. You can let the balance accumulate for decades. After age 65, you can withdraw HSA funds for any reason without the 20% penalty, though non-medical withdrawals are still subject to income tax. Many people use HSAs as retirement savings vehicles and do not touch the balance until later in life.

If I have two HSAs, do the balances roll over separately?

Yes. Each HSA account is separate, and each balance rolls over independently. However, the IRS limits total contributions across all your HSAs combined. If you have two accounts, you cannot contribute the full limit to each one — the combined contributions cannot exceed the annual limit for your coverage type. Any balances you have accumulated roll over without issue, but future contributions are limited.

Can my employer take back HSA funds if I leave the company?

No. The HSA is your personal account, and your employer cannot reclaim the balance. If your employer contributed money to the account, that money is yours to keep once it is deposited. You can take the account with you when you leave, and the balance remains available for your use.
