How an HSA works once you have one

An HSA (Health Savings Account) is a bank account that holds money specifically for medical expenses. You put pre-tax dollars in, the money grows tax-free, and you withdraw it to pay for may have access to medical costs without paying taxes on those withdrawals. Unlike a flexible spending account (FSA), money you don't spend stays in the account year to year — it does not disappear on December 31st.

The account itself is held at a bank or financial institution, similar to a regular savings account. Your employer may set one up for you, or you can open one independently if you have a high-deductible health plan (HDHP). Once the account exists, you control when and how you spend the money.

Key Takeaways

  • You can withdraw HSA money for any may have access to medical expense — copays, deductibles, prescriptions, dental work, vision care, and some medical equipment — without paying income tax on the withdrawal.
  • Most HSAs come with a debit card or checkbook, so you can pay providers directly; some require you to pay out of pocket first and then request reimbursement from the HSA.
  • Money left in your HSA at the end of the year rolls over and earns interest or investment returns, so the account can grow into a long-term savings tool.
  • Withdrawals for non-medical expenses are taxed as income and charged a 20 percent penalty if you are under age 65; after 65, the penalty goes away but income tax still applies.
  • You must keep receipts and records showing that each withdrawal was for a may have access to medical expense, in case the IRS asks for proof.

What counts as a may have access to medical expense

The IRS maintains a list of medical expenses you can pay with HSA funds without tax consequences. The list is long and includes the obvious ones: doctor visits, hospital stays, prescription drugs, and dental and vision care. It also covers less obvious items like hearing aids, crutches, wheelchairs, and insulin supplies.

Some expenses that sound medical do not may have access to. Over-the-counter pain relievers, cold medicine, and vitamins are not covered unless a doctor prescribes them. Cosmetic procedures, gym memberships, and general wellness programs are not covered. If you are unsure whether a specific expense qualifies, ask your HSA provider or check the IRS Publication 502, which lists may have access to and non-may have access to expenses in detail.

Dental and vision expenses are fully covered if they treat a medical condition — a root canal, crown, or glasses for vision correction all count. Orthodontics and cosmetic dentistry typically do not, unless they are medically necessary.

How to access and spend HSA money

Most HSAs come with a debit card that works like a regular bank card. You can use it at pharmacies, doctor offices, and hospitals to pay for may have access to expenses directly. The card is linked to your HSA account, so the money comes straight from your HSA balance. Some providers also issue a checkbook or allow online bill pay.

If your HSA does not have a debit card, or if you prefer to pay out of pocket, you can request a reimbursement. You pay the medical provider with your own money, then submit a claim to your HSA provider with a receipt or invoice showing what you paid for. The HSA provider reviews the claim and transfers the money to your bank account, usually within one to two weeks.

A few HSAs allow you to invest your balance in mutual funds or other securities, similar to a retirement account. If your HSA offers this option, money you do not plan to spend soon can grow over time. Investment options and fees vary by provider, so check what your specific HSA offers.

Keeping records and proving expenses

The IRS does not require you to submit receipts when you withdraw HSA money, but you must keep them. If the IRS audits your account, you need to show that each withdrawal was for a may have access to medical expense. A receipt from a pharmacy, doctor's office, or hospital is the standard proof. For reimbursement claims, your HSA provider will ask for the receipt before they approve the payment.

Store receipts in a folder, envelope, or digital file — however works for you. Many people photograph receipts with their phone or scan them. Keep records for at least three years after the year in which you made the withdrawal, since that is how far back the IRS can typically audit.

If you use the debit card, the transaction will show up on your HSA statement, but the statement alone does not prove the expense was medical. The receipt is what proves it. If you lose a receipt, contact the provider and ask for a duplicate or a statement showing the date, amount, and nature of the charge.

What happens if you spend HSA money on non-medical expenses

If you withdraw HSA money for something that is not a may have access to medical expense, you owe income tax on that amount plus a 20 percent penalty. For example, if you withdraw $500 for a non-medical expense and you are in the 22 percent tax bracket, you would owe $110 in income tax plus $100 in penalty — a total of $210 on top of the $500 you spent.

The penalty does not apply after you turn 65. At that point, you can withdraw money for any reason, and you only owe income tax on non-medical withdrawals. This makes an HSA a useful long-term savings tool if you do not spend all the money while you are working.

If you accidentally use your HSA debit card for a non-medical expense, contact your HSA provider right away. Some providers allow you to return the funds within a short window to avoid the tax and penalty. The sooner you catch the mistake, the better your options.

HSA rules when you change jobs or leave your employer

Your HSA belongs to you, not your employer. If you change jobs, leave your job, or retire, the account stays open and the money stays yours. You can continue to use it for medical expenses for the rest of your life. Some employers stop contributing to your HSA when you leave, but your existing balance does not disappear.

If your new employer offers an HSA, you can keep your old account or roll the balance into the new one. Many people keep the old account because it may have lower fees or better investment options. You can have multiple HSAs at the same time, though your total contributions across all accounts cannot exceed the annual IRS limit.

If your new job does not offer an HSA, or if you are self-employed, you can open an individual HSA on your own as long as you have a high-deductible health plan. The rules and contribution limits are the same.

Frequently Asked Questions

Can I use my HSA to pay for my spouse's or child's medical expenses?

Yes. HSA money can pay for the medical expenses of your spouse and any dependent you claim on your tax return, even if they are not covered by your health plan. You do not need to be on the same insurance plan. Keep receipts showing the expense and who it was for.

What if I do not spend all my HSA money in a year?

The money rolls over to the next year. Unlike a flexible spending account, there is no "use it or lose it" rule. Your HSA balance can grow year after year, and you can use it whenever you need it — even decades later in retirement.

Can I withdraw HSA money to pay my health insurance premium?

No, with one exception: you can use HSA funds to pay for COBRA continuation coverage or health insurance premiums while you are receiving unemployment benefits. You cannot use it for regular monthly premiums while you are employed. You can use it for out-of-pocket costs like copays and deductibles.

Do I have to report HSA withdrawals on my tax return?

No, as long as all withdrawals were for may have access to medical expenses. If you made any non-medical withdrawals, you report those on Form 8889 when you file your taxes. Your HSA provider sends you a Form 1099-SA showing all withdrawals; keep it with your tax records.

What if my HSA provider goes out of business?

Your money is protected. HSA funds are held in trust and are not considered the provider's assets, so they cannot be seized if the company fails. Your funds would be transferred to another HSA provider or returned to you. Contact your state's banking regulator if you have concerns about your provider's stability.
