How to Use Your HSA: Spending, Saving, and Tax Benefits

How to spend and save money in your HSA

An HSA works like a checking account with a debit card, but the money you withdraw for may have access to medical expenses comes out tax-free. You can spend from your HSA immediately on may be able to access costs — copays, prescriptions, dental work, vision care, medical equipment — or leave the money untouched to grow as an investment for future health costs. The choice is yours each time you need care.

Most HSAs come with a debit card that works at pharmacies and medical offices. Some require you to pay out of pocket first, then submit a receipt to your HSA provider for reimbursement. A few plans let you do both. Check with your specific HSA provider to see which method they support.

The tax benefit works the same whether you spend the money now or later: money going in is not subject to income tax, money coming out for medical expenses is not taxed, and any interest or investment gains stay tax-free as long as you use them for may have access to medical costs. This makes an HSA different from a regular savings account, where you pay taxes on the interest.

Key Takeaways

• You can withdraw HSA money tax-free for may have access to medical expenses like copays, prescriptions, dental care, and medical equipment whenever you need it.
• Most HSAs come with a debit card for direct payment at medical providers, or you can pay yourself and request reimbursement from your HSA provider.
• Money left unspent in your HSA rolls over year to year and can be invested to grow, unlike flexible spending accounts that have a use-it-or-lose-it rule.
• Withdrawals for non-medical expenses are taxed as income plus a 20 percent penalty, so keep receipts to prove your spending was medical.
• You can withdraw money to reimburse yourself for medical expenses from years past, even decades ago, as long as you have the original receipt.

What counts as a may have access to medical expense

The IRS publishes a list of may have access to medical expenses, and it is longer than most people expect. The obvious ones are copays, deductibles, prescriptions, and hospital bills. But it also includes dental work, vision care, hearing aids, crutches, wheelchairs, insulin, and over-the-counter medications like pain relievers and allergy pills — as long as you have a prescription or a doctor's note saying you need them.

Some costs that sound medical do not count. Cosmetic surgery, gym memberships, and vitamins without a medical reason are not covered. Teeth whitening is not covered, but root canals are. Sunscreen for general use is not covered, but sunscreen prescribed for a skin condition is. The rule is whether a doctor prescribed or recommended the expense to treat or prevent a specific medical condition.

Keep every receipt. If you withdraw money and the IRS later questions whether it was a medical expense, you need the original receipt to prove it. Many people keep a folder or take photos of receipts and store them digitally. You do not have to submit receipts when you withdraw the money — you only need them if you are audited.

Using your HSA as a long-term investment account

Unlike a flexible spending account (FSA), which requires you to spend the money within the calendar year or lose it, an HSA rolls over every year. Money you do not spend stays in the account and can be invested in mutual funds, stocks, or bonds through your HSA provider. This turns an HSA into a retirement savings tool if you do not need the money for medical expenses right now.

The investment options vary by provider. Some HSAs offer only a savings account with minimal interest. Others let you invest in a range of funds similar to a 401(k). Check your provider's website or call their customer service line to see what investment choices are available to you. If your current provider has limited options, you can sometimes roll your HSA to a different provider that offers better investments.

If you invest HSA money and the market goes down, you can still withdraw it tax-free for medical expenses. If the market goes up, the gains are tax-free as long as you use the money for may have access to medical costs. This is a significant advantage over a taxable brokerage account, where you would owe capital gains tax on the profits.

The mechanics of HSA withdrawals and reimbursements

When you use your HSA debit card at a pharmacy or doctor's office, the transaction is usually processed immediately and the money leaves your account. Some providers require you to categorize the expense or submit a receipt within a certain time frame to keep the withdrawal tax-free. If you do not provide proof that it was a medical expense, the provider may treat it as a non-medical withdrawal and report it to the IRS.

If you pay for medical care with your own money and want to reimburse yourself from your HSA later, contact your provider and request a reimbursement. You will need to submit a receipt or invoice showing the date, amount, and nature of the expense. The provider will transfer the money to your bank account or HSA debit card, usually within a few business days.

You can reimburse yourself for medical expenses from previous years, even many years ago, as long as you have the original receipt and the expense was incurred after you opened your HSA. Some people use this strategy to let their HSA grow invested for decades, then reimburse themselves for old medical costs when they need cash in retirement. This is legal and common.

Penalties and taxes for non-medical withdrawals

If you withdraw money from your HSA for something that is not a may have access to medical expense, you owe income tax on that amount plus a 20 percent penalty. The penalty applies only to the non-medical portion of the withdrawal, not to the entire account. For example, if you withdraw $1,000 and $200 of it is for a non-medical expense, you owe income tax and the 20 percent penalty only on the $200.

After age 65, the 20 percent penalty goes away. You can withdraw money for any reason without the penalty, though you still owe income tax on non-medical withdrawals. This makes an HSA similar to a traditional IRA at that point — you can use it for retirement expenses of any kind, but non-medical withdrawals are taxed as ordinary income.

If you are unsure whether an expense qualifies, do not withdraw the money until you have checked. The IRS publishes a full list of may have access to medical expenses on its website, and your HSA provider's customer service can also answer questions about specific costs. It is easier to ask before you withdraw than to deal with penalties and taxes later.

Coordinating your HSA with other health accounts

You cannot have an HSA and an FSA at the same time, with one exception: you can have a limited-purpose FSA that covers only dental and vision expenses while you have an HSA. A regular FSA and an HSA cannot coexist in the same year.

If you have a dependent care FSA (for childcare costs), that does not conflict with an HSA. Dependent care FSAs and HSAs serve different purposes and can run simultaneously. However, you cannot use HSA money to pay for dependent care — that is a separate category of expense.

If you switch from an FSA to an HSA, any money left in the FSA at the end of the year is forfeited. Plan your FSA spending carefully in your final year with that account, or you will lose the balance. Once you move to an HSA, you have the rollover protection that FSAs do not offer.

Keeping records and staying compliant

The IRS does not require you to submit receipts when you withdraw HSA money, but you must keep them for your records. If you are audited, you need to show that the money was spent on may have access to medical expenses. A receipt should show the date, the provider's name, the amount, and what was purchased or treated.

Many HSA providers send you an annual statement showing all withdrawals and deposits. This statement is for your records and is not filed with the IRS. Keep your receipts organized — in a folder, a spreadsheet, or a photo album on your phone — so you can match them to the statement if needed.

If you receive a notice from the IRS questioning an HSA withdrawal, respond promptly with your receipts. If you cannot provide proof that a withdrawal was for a medical expense, you will owe the income tax and 20 percent penalty retroactively, plus interest. This is rare, but it happens when people use HSAs for non-medical expenses and do not keep documentation.

Frequently Asked Questions

Can I use my HSA debit card at any store, or only at medical providers?

HSA debit cards are designed for medical expenses and work at pharmacies, doctor's offices, hospitals, and medical supply stores. They may not work at general retailers. If you try to use the card for a non-medical purchase, the transaction may be declined or flagged by your provider. Always use your HSA card only for may have access to medical expenses.

What happens to my HSA if I leave my job?

Your HSA belongs to you, not your employer. When you leave your job, the account stays open and the money remains yours. You can continue to use it for medical expenses and can keep investing it. You may need to move the account to a new provider if your employer's plan closes, but the money does not disappear. Contact your HSA provider to learn about your options.

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

Yes. HSA money can be used for may have access to medical expenses of you, your spouse, and your dependents, regardless of whether they are covered under your health plan. You do not need to be on the same insurance policy. Keep receipts showing the person's name and the medical expense to document the withdrawal.

What if I do not spend all my HSA money by the end of the year?

Unlike a flexible spending account, HSA money rolls over to the next year with no limit. You can let it accumulate for decades if you choose. Some people use this to build a large balance and invest it for retirement, then withdraw money for medical expenses later in life. There is no deadline to spend HSA money.

Can I withdraw HSA money to pay for health insurance premiums?

You cannot use HSA money to pay premiums for regular health insurance. However, you can use it to pay premiums for long-term care insurance, COBRA coverage (if you lose your job), and Medicare premiums after age 65. Check with your HSA provider about which types of insurance premiums may have access to in your situation.
