What you can spend HSA money on right now
Your HSA funds work like a debit card for medical expenses the IRS allows. You can spend them on doctor visits, prescriptions, dental work, vision care, mental health treatment, and medical equipment—but only if you have a high-deductible health plan (HDHP) and meet the income limits your plan sets. The moment you spend HSA money on a non-medical expense, you owe income tax on that amount plus a 20% penalty, so the line between allowed and forbidden matters.
The IRS publishes a list of covered expenses in Publication 969, but the practical version is simpler: if a doctor prescribes it or a licensed provider bills for it, it usually counts. Over-the-counter items are trickier—you can buy pain relievers, allergy medicine, and bandages, but you need a prescription or a letter from your doctor saying the item is medically necessary. Gym memberships and vitamins do not count, even if your doctor recommends them. Cosmetic procedures do not count unless they treat an injury or illness.
Key Takeaways
- HSA money rolls over year to year and grows tax-free if you invest it, making it the only account that saves you money three ways: on deposits, growth, and withdrawals.
- You can spend HSA funds on any IRS-approved medical expense without a receipt at the time of purchase, but keep records in case the IRS audits you later.
- If you leave your HDHP or turn 65, you can still use your HSA balance, but the rules change—after 65, non-medical withdrawals are taxed as income but the 20% penalty disappears.
- Investing HSA money in mutual funds or stocks instead of leaving it in cash means your balance grows tax-free and compounds over decades, turning it into a retirement account.
- You can reimburse yourself for past medical expenses years later using HSA funds, as long as you have receipts and the expense happened after your HSA opened.
Spending without receipts and keeping records anyway
You do not need a receipt to spend HSA money at the time you buy something—you can swipe your HSA debit card at a pharmacy or doctor's office and walk out. But the IRS can audit you years later and ask for proof that the expense was medical. If you cannot show a receipt or an explanation of benefits from your insurance, the IRS will treat that withdrawal as taxable income plus the 20% penalty.
Keep receipts in a folder, take photos of them, or save emails from your provider showing what you paid for. If you lose a receipt, ask your doctor's office or pharmacy for a duplicate—most will print one. For insurance claims, your explanation of benefits is proof enough. The key is having something that shows the date, the provider, and what the money was for. You do not need to send receipts to your HSA provider unless they ask; you just need them if an audit happens.
Investing your HSA instead of leaving it in savings
Most HSA providers let you invest your balance in mutual funds, index funds, or stocks the same way you would in a brokerage account. The money grows tax-free, and when you withdraw it for medical expenses, you pay no tax on the growth. This turns your HSA into a long-term retirement account if you do not need the money for medical bills right now.
The trade-off is risk: if you invest in stocks and the market drops, your balance drops too. If you invest in bonds or stable-value funds, your growth is slower but steadier. Many people keep a small amount in the HSA savings account (enough to cover a deductible or two) and invest the rest. Check your HSA provider's website to see what investment options they offer—some have low fees and broad choices, others charge per trade or limit you to a few funds. Starting to invest early means decades of tax-free growth, which compounds into real money by retirement.
Reimbursing yourself for old medical bills
You can withdraw HSA money to pay yourself back for medical expenses you paid out of pocket years ago, as long as the expense happened after your HSA opened and you have a receipt. This is useful if you paid for something with a personal credit card or cash and did not have HSA funds at the time. You can reimburse yourself at any point in the future—there is no time limit.
The process is simple: gather the receipt, calculate the amount you paid, and request a withdrawal from your HSA provider. Some providers let you do this online; others require a form. This strategy lets you keep HSA money invested longer—if you paid $500 for dental work five years ago and your HSA balance has grown to $8,000, you can withdraw $500 now and let the rest keep growing tax-free. Just make sure you have the receipt and that the expense is IRS-approved.
What happens when you leave your HDHP or turn 65
If you switch to a different health plan that is not an HDHP, you stop being able to contribute to your HSA, but the money you already have stays yours and keeps growing tax-free. You can still withdraw it for medical expenses at any time without penalty. You just cannot add new money to it.
At age 65, the rules shift: you can withdraw HSA money for any reason without the 20% penalty, though non-medical withdrawals are taxed as regular income. This makes your HSA function like a traditional IRA at that point—useful if you need the money for living expenses in retirement. Medical expenses still come out tax-free. If you die, your beneficiary inherits the HSA, but the tax treatment depends on who the beneficiary is and what they use the money for—check your HSA provider's rules on this.
Avoiding the 20% penalty and tax mistakes
The 20% penalty applies only to non-medical withdrawals before age 65. If you withdraw $1,000 for something the IRS does not allow, you owe income tax on that $1,000 plus $200 in penalties. The income tax rate depends on your tax bracket, so the total cost could be 32% to 47% of the withdrawal.
To avoid this, know the line between medical and non-medical: cosmetic procedures, gym memberships, vitamins without a prescription, and over-the-counter items without a doctor's letter are all forbidden. If you are unsure, ask your HSA provider or check Publication 969 on the IRS website. Some expenses are gray—ask your provider in writing and keep their response. If your provider says it is allowed and you follow their guidance, you have a defense if the IRS questions it later.
Using HSA funds for family members
You can spend your HSA money on medical expenses for your spouse and dependents, even if they are not on your health plan. Your spouse's dental work, your child's glasses, your parent's prescription—all count if they are your dependent for tax purposes. You do not need to be on the same insurance plan.
The key is that the person must be your dependent or spouse. If you pay for a friend's medical bill, that does not count. Keep receipts showing who the expense was for, especially if the name on the receipt is not yours. This matters if the IRS audits you and asks why you withdrew money but have no medical bills in your own name.
Frequently Asked Questions
Can I use my HSA to pay my health insurance premium?
No, not your regular monthly premium. You can use HSA funds to pay for COBRA continuation coverage, long-term care insurance, or health insurance premiums while you are unemployed and receiving unemployment benefits. You cannot use it for your employer's health plan premium or Medicare premiums before age 65.
What if I withdraw money and later find out it was not a covered expense?
You owe income tax plus the 20% penalty on that amount. If you catch the mistake before filing taxes, you can deposit the money back into your HSA and avoid the penalty. If you discover it after filing, you may need to amend your return or pay the penalty when the IRS audits you.
Do I have to spend my HSA money every year or lose it?
No. HSA money rolls over year to year with no limit. You can accumulate it for decades and spend it whenever you want, even in retirement. This is different from a flexible spending account (FSA), which has a "use it or lose it" rule.
Can I use my HSA to pay for therapy or mental health treatment?
Yes. Mental health care from a licensed therapist, psychiatrist, or counselor counts as a covered medical expense. Copays, deductibles, and out-of-pocket costs all may have access to. You can use HSA funds for both in-person and telehealth mental health visits.
What happens to my HSA if I die?
Your beneficiary inherits the balance. If your spouse is the beneficiary, they can treat it as their own HSA and continue using it tax-free for medical expenses. If someone else is the beneficiary, they owe income tax on the full balance, though the 20% penalty does not apply. Check your HSA provider's beneficiary form to make sure it is filled out correctly.
