Your HSA money does not expire, but the account itself can close if you stop meeting the requirements

The funds you put into a health savings account stay in the account indefinitely—there is no "use it or lose it" deadline on the money itself. However, the account can close if you no longer have a high-deductible health plan (HDHP), which is the insurance requirement to keep an HSA open. Once the account closes, you can still access the money that remains, but you cannot add new contributions, and withdrawals for non-medical expenses will be taxed as income plus hit with a 20% penalty.

The confusion often comes from mixing up two different things: the money inside the account (which does not expire) and your ability to contribute to it (which stops when you lose HDHP coverage). Understanding the difference matters because it changes what you can do with the account going forward.

Key Takeaways

  • HSA funds never expire and roll over year to year, even if you do not spend them in the calendar year you contributed.
  • Your HSA account closes automatically if you switch to a non-HDHP insurance plan, Medicare, or Medicaid, but the money stays accessible.
  • After your account closes, you can withdraw money for past or current medical expenses without penalty, but new non-medical withdrawals are taxed as income plus 20%.
  • If you regain HDHP coverage later, you can reopen an HSA and resume contributions, but you cannot recover the closed account itself.

What happens to the money when your account closes

When you lose HDHP coverage—whether by switching to a standard PPO plan, enrolling in Medicare, or signing up for Medicaid—your HSA account closes. The money does not disappear. You retain ownership of every dollar in the account and can withdraw it at any time. The account simply stops accepting new contributions from you or your employer.

The tax treatment of withdrawals changes once the account is closed. Money you withdraw for may have access to medical expenses (past, present, or future) remains tax-free and penalty-free, even years after the account closed. But if you withdraw money for anything else—groceries, rent, a vacation—that withdrawal is taxed as ordinary income, and you owe a 20% penalty on top of the income tax.

Some people keep closed HSA accounts open indefinitely just to hold the money, since there is no annual fee or requirement to use it. Others roll the remaining balance into a new HSA if they regain HDHP coverage later. The choice is yours.

When you lose HDHP coverage and what triggers account closure

Your HSA account closes automatically when you no longer meet the HSA may be able to access rules. The most common trigger is switching health insurance. If you move from an HDHP to a standard health plan, your account closes at the moment your new coverage begins. You do not have to do anything—the closure is automatic.

Other events that close an HSA include enrolling in Medicare (even Part A alone), signing up for Medicaid, or becoming a dependent on someone else's tax return if that person claims you. Some employers also close HSAs when an employee leaves the company, though the money remains yours and you can often transfer it to an HSA with a different provider.

The closure date matters for tax purposes. If you close your account partway through the year, you can only contribute to the HSA for the months you were may be able to access. The IRS has specific rules about this, and your HSA provider should send you a form documenting when the account closed.

Withdrawing money after your account closes

Once your account is closed, you can withdraw money whenever you need it. There is no time limit. You can take out $100 today and $500 five years from now—the money is yours to access.

The key is documenting what the withdrawal is for. If you withdraw $2,000 and claim it was for medical expenses, keep receipts or invoices showing those expenses. The IRS can audit HSA withdrawals years later, so a paper trail protects you. may have access to medical expenses include doctor visits, prescriptions, dental work, vision care, medical equipment, and many other health-related costs—but not insurance premiums (with limited exceptions) or over-the-counter items unless prescribed by a doctor.

If you cannot document a withdrawal as a may have access to medical expense, it will be taxed as income plus the 20% penalty. Some people withdraw money gradually over time, documenting each withdrawal carefully. Others leave the money in the closed account and only withdraw it when they have clear medical expenses to match against it.

Reopening an HSA if you regain HDHP coverage

If you switch back to an HDHP later—whether with the same employer, a different employer, or through the individual market—you can open a new HSA. You cannot reopen the old closed account, but you can open a fresh one and resume contributions immediately.

When you open a new HSA, you start with a zero balance. The money in your old closed account stays there; it does not transfer automatically. You can request a trustee-to-trustee transfer to move the balance from the old account to the new one, but you have to initiate that transfer yourself. Contact the provider holding the old account and ask them to transfer the balance to your new HSA provider. This process typically takes one to two weeks.

If you do not transfer the old balance, it simply remains in the closed account. You can still withdraw from it for medical expenses, but it will not be part of your active HSA that you are contributing to and using regularly.

The difference between account closure and money expiration

Many people worry that if they do not spend their HSA money by December 31, it disappears. That is not how HSAs work. Unlike a flexible spending account (FSA), which has a strict "use it or lose it" rule, HSA money rolls over year after year. You can accumulate thousands of dollars in an HSA over your working life and never touch it.

The only time you lose access to HSA money is if the account provider goes out of business or if you do something that violates HSA rules (like using the money for non-medical expenses while the account is still active, which triggers penalties). But the money itself does not expire based on time.

This is why HSAs are often called "triple tax-advantaged": contributions are tax-deductible, growth is tax-free, and withdrawals for medical expenses are tax-free. The long-term nature of the account—the fact that money does not expire—makes it a powerful tool for saving for future healthcare costs, even in retirement.

Using a closed HSA in retirement

A closed HSA can be particularly useful in retirement. Once you turn 65, you can withdraw money from your HSA for any reason without the 20% penalty (though non-medical withdrawals are still taxed as income). This makes a closed HSA function like a traditional IRA at that point, except the money is still available tax-free for medical expenses.

Many people close their HSAs when they enroll in Medicare at 65, but they keep the account open to hold the money. They can then withdraw for Medicare premiums, copays, deductibles, and other medical costs tax-free. Any money they do not use for medical expenses can be withdrawn for living expenses without penalty, though it will be taxed as income.

If you plan to use your HSA this way, keep good records of your medical expenses throughout retirement. The IRS allows you to reimburse yourself for medical expenses from years past, as long as you have documentation. Some retirees use this strategy to let their HSA grow untouched for decades, then reimburse themselves for old medical expenses in retirement when they need the cash.

Frequently Asked Questions

Can I use my HSA money after I turn 65?

Yes. After 65, you can withdraw HSA money for any reason without the 20% penalty. Medical withdrawals remain tax-free; non-medical withdrawals are taxed as income but not penalized. This makes a closed HSA valuable in retirement for covering Medicare costs and other healthcare expenses.

What happens to my HSA if I switch jobs?

Your HSA stays with you—it is not tied to your employer. You can keep the account open with the same provider, or you can transfer the balance to a new HSA with a different provider. Your new employer may offer their own HSA, but you are not required to use it. You can keep your old account and contribute to it through payroll deductions if your new employer allows it.

Do I have to close my HSA when I enroll in Medicare?

Your HSA closes automatically when you enroll in Medicare Part A or B. However, you can keep the account open and continue to withdraw money from it. You simply cannot make new contributions once Medicare coverage begins. Some people intentionally delay Medicare enrollment to keep contributing to their HSA longer.

Can I withdraw money from a closed HSA for expenses from years ago?

Yes. You can withdraw money from a closed HSA to reimburse yourself for medical expenses from any year in the past, as long as the expenses occurred after you opened the HSA. Keep receipts or invoices as proof. The IRS allows this strategy, and it is commonly used to access HSA money in retirement.

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

HSA money passes to your beneficiary as part of your estate. If your spouse inherits the HSA, they can treat it as their own and continue using it. If a non-spouse inherits it, the full balance becomes taxable income to them in the year of your death, though withdrawals for your medical expenses remain tax-free.
