Yes, health savings account money carries over year to year, and you never lose it by not spending it

Unlike a flexible spending account (FSA), which operates on a "use it or lose it" rule, an HSA is yours to keep. Any money you contribute and don't spend in a given calendar year rolls into the next year. The balance stays in your account indefinitely—even if you change jobs, switch health plans, or retire. You own the account and the money in it, which is why HSAs are sometimes called "triple tax-advantaged": contributions are tax-deductible, growth is tax-free, and withdrawals for may have access to medical expenses are tax-free.

The one exception is if you withdraw money for non-medical expenses before age 65. In that case, you owe income tax on the withdrawal plus a 20% penalty. After age 65, you can withdraw money for any reason without the penalty (though you still owe income tax on non-medical withdrawals).

Key Takeaways

  • HSA balances roll over automatically each year and never expire, unlike FSAs which reset annually.
  • You can accumulate HSA money over decades and use it for medical expenses whenever you need it, even years later.
  • If you withdraw HSA money for non-medical expenses before age 65, you pay income tax plus a 20% penalty on that amount.
  • Your HSA remains yours even if you change employers, health plans, or retire, as long as you keep the account open.
  • After age 65, you can withdraw HSA money for any reason without penalty, though non-medical withdrawals are still taxable income.

How the rollover works in practice

On December 31, whatever balance sits in your HSA account stays there. On January 1, that same balance is available to you. There is no deadline to spend it, no forfeiture, no reset button. If you contribute $4,000 in 2024 and spend $1,500 on medical expenses, you have $2,500 left. That $2,500 is still yours in 2025, 2026, and beyond.

Many people use this feature strategically: they contribute the maximum allowed each year, spend only what they must on current medical expenses, and let the rest grow. Over time, an HSA can become a substantial medical savings fund. Some people treat it as a retirement account specifically for health costs, contributing and investing the money rather than spending it immediately.

The account itself must stay open for the money to remain yours. If you close an HSA, you can withdraw the balance without penalty (though you owe income tax on any earnings), but the account no longer exists. Most people keep their HSA open even after leaving a job or changing health plans.

What happens when you change jobs or health plans

Your HSA is separate from your employer and your health insurance plan. When you leave a job, your HSA does not disappear and does not revert to your employer. The money is yours, and you keep it. You may need to move the account to a new HSA custodian (a bank or financial institution that holds HSA accounts), but the balance transfers with you.

Similarly, if you switch health plans—even to a plan that is not HSA-compatible—your existing HSA balance remains yours. You cannot make new contributions to an HSA if your new plan does not may have access to, but you can still withdraw from the old balance for medical expenses. Some people keep an HSA open for years after switching to a non-HSA plan, using it as a dedicated medical fund.

Investment growth and how it affects your balance

Many HSA custodians let you invest your balance in mutual funds, stocks, or other securities, similar to a 401(k). Any growth on that investment is tax-free as long as you use the money for may have access to medical expenses. If your $5,000 HSA balance grows to $7,000 through investment gains, that entire $7,000 can be withdrawn tax-free for medical costs.

If you withdraw invested HSA money for non-medical expenses before age 65, you owe income tax and a 20% penalty on the earnings portion only, not on your original contributions. For example, if you contributed $5,000 and it grew to $7,000, and you withdraw $7,000 for a non-medical reason at age 50, you owe tax and penalty only on the $2,000 gain.

Withdrawals after age 65

At age 65, the rules change significantly. You can withdraw HSA money for any reason without the 20% penalty. However, if the withdrawal is for a non-medical expense, you still owe ordinary income tax on it. This makes an HSA function like a traditional IRA after 65—you can use it for anything, but non-medical withdrawals are taxable.

Many people use this feature to their advantage: they contribute and invest in their HSA during their working years, let it grow tax-free, and then use it to cover medical expenses in retirement (which are typically substantial). If they need the money for something else after 65, they can take it without penalty, though they pay income tax.

Tracking your balance and keeping records

Your HSA custodian sends you statements showing your balance and all transactions. Keep these records, especially if you plan to reimburse yourself for past medical expenses years later. The IRS does not require you to submit receipts when you withdraw, but you must be able to prove that the expense was medical and that you have not already been reimbursed by insurance or another source.

Some people save receipts and invoices for years, then withdraw from their HSA to reimburse themselves long after the expense occurred. This is legal and common—there is no time limit on when you can withdraw for a past medical expense, as long as the expense happened after you opened the HSA.

What counts as a may have access to medical expense

may have access to expenses include doctor visits, prescriptions, dental work, vision care, mental health treatment, and many other health-related costs. They do not include health insurance premiums (with narrow exceptions for COBRA, Medicare, or long-term care insurance), cosmetic procedures, or over-the-counter items like vitamins unless prescribed by a doctor.

The IRS publishes a detailed list of may have access to expenses. When in doubt, check the list or ask your HSA custodian before withdrawing. If you withdraw for a non-may have access to expense, you owe tax and penalty on that amount, even if you thought it was covered.

Frequently Asked Questions

Yes, as long as your spouse is a dependent on your tax return. You can withdraw HSA money to pay for your spouse's may have access to medical expenses, and the money rolls over to cover future expenses for either of you.

What if I have money left in my HSA when I die?
