You keep the money in your HSA—it does not disappear at the end of the year

Your HSA balance rolls forward every year. Unlike a flexible spending account (FSA), which has a "use it or lose it" rule, an HSA lets you keep whatever you do not spend. The money stays in your account indefinitely, and you can use it for may have access to medical expenses whenever you need it—this year, next year, or decades from now.

The account itself belongs to you, not your employer. Even if you leave your job, change health plans, or retire, the HSA goes with you. You control it, and the money inside it is yours to keep.

Key Takeaways

  • HSA funds do not expire at the end of the year and carry over automatically to the next year.
  • You own the HSA and the money in it, even if your employer contributed to it or you opened it through your job.
  • Once you turn 65, you can withdraw HSA money for any reason without penalty, though non-medical withdrawals are taxed as income.
  • If you close your HSA or stop contributing, the money already in the account remains yours and can still be used for medical expenses.

How the money stays in your account year to year

Each January, your HSA balance from the previous December carries forward. There is no deadline to spend it, no forfeiture date, and no requirement to empty the account. This is the core difference between an HSA and an FSA. An FSA typically has a "use it or lose it" rule—you forfeit unspent money at the end of the plan year (though some employers offer a short grace period or a small carryover amount).

An HSA has no such limit. You can accumulate money in the account for years, even decades. Some people use their HSA as a long-term savings vehicle, contributing the maximum each year and only withdrawing for medical expenses when they truly need to. Others spend down their balance regularly. Both approaches are allowed.

What counts as a may have access to medical expense you can pay from your HSA

You can withdraw HSA money tax-free to pay for may have access to medical expenses—costs that the IRS recognizes as legitimate healthcare. These include doctor visits, prescriptions, dental work, vision care, mental health treatment, and hospital stays. Copays, coinsurance, and deductibles all count. So do medical equipment like crutches, wheelchairs, and hearing aids, as well as certain over-the-counter items like pain relievers and allergy medicine (though you need a prescription or doctor's note for OTC drugs as of 2020).

Expenses do not have to be for you alone. You can use HSA money to pay for may have access to medical costs for your spouse and dependents, even if they are not covered under your health plan. The IRS publishes a full list of what qualifies; when in doubt, check the IRS Publication 502 or ask your HSA provider.

What happens if you withdraw money for non-medical reasons

If you withdraw HSA money for something that is not a may have access to medical expense, you owe income tax on that amount. You also owe a 20 percent penalty on the withdrawal—unless you are 65 or older. Once you turn 65, the penalty goes away, and you can withdraw money for any reason. You will still owe income tax on non-medical withdrawals, but not the penalty.

This penalty applies only to the amount you withdraw for non-medical use, not to your entire HSA balance. If you have $5,000 in your account and withdraw $500 for a non-medical reason, you pay tax and the 20 percent penalty only on that $500.

What happens to your HSA if you leave your job

Your HSA is yours to keep. When you leave your employer, the account does not close and the money does not go back to your company. You own it outright. You can take the HSA with you to a new job, roll it into a new HSA if your new employer offers one, or keep it open on your own through an HSA provider like a bank or investment firm.

The only requirement is that you remain enrolled in a high-deductible health plan (HDHP) to continue contributing new money to the HSA. If you switch to a non-HDHP plan—such as a traditional PPO or HMO—you can no longer add money to the account. But the money already in the HSA stays there and can still be used for medical expenses for the rest of your life.

Using your HSA after retirement or at age 65

At 65, your HSA becomes more flexible. You can withdraw money for any reason without the 20 percent penalty. Non-medical withdrawals are still taxed as ordinary income, but the penalty disappears. Many people use this as an opportunity to reimburse themselves for past medical expenses they paid out of pocket, or to use the HSA like a regular retirement account once they reach Medicare age.

If you are on Medicare, you can still use HSA funds to pay Medicare premiums, copays, coinsurance, and deductibles. You cannot use HSA money to pay for Medicare supplemental insurance premiums, but you can use it for most other Medicare-related costs. Keep receipts for any medical expenses you pay out of pocket—you can reimburse yourself from your HSA years later, even decades later, as long as you have documentation.

Keeping records of your HSA spending

The IRS does not require you to submit receipts when you withdraw HSA money, but you must keep records to prove that withdrawals were for may have access to medical expenses. If the IRS audits you, you need to show documentation—receipts, invoices, or statements from providers—that the money went toward legitimate healthcare costs.

Many HSA providers send you an annual statement showing your balance and transactions. Keep that statement along with your receipts. If you reimburse yourself for an old medical expense years later, keep the original receipt or a record of the expense date and amount. The longer you hold money in your HSA without withdrawing it, the more important it is to maintain clear records of what you spent it on.
