You can use your HSA (Health Savings Account) in three main ways: pay for qualified medical expenses now, invest the balance for long-term growth, or save receipts and reimburse yourself years later for tax-free cash. Most people only use the first option, but the real power of an HSA comes from understanding all three.
Ways to Pay With Your HSA
The most straightforward way to use your HSA is to pay for medical expenses directly. Most HSA providers issue a debit card linked to your account, and you can swipe it at the doctor’s office, pharmacy, dentist, or vision center just like any other card. The money comes out of your HSA balance immediately, tax-free.
If you pay out of pocket first, you can reimburse yourself afterward. The process depends on your provider, but the options typically include an online transfer to a linked bank account, an electronic transfer to another account with the same provider, or writing yourself a check from your HSA checkbook. You’ll want to keep your receipt in case the IRS ever asks you to prove the expense was qualified.
What You Can Spend HSA Money On
The IRS defines “qualified medical expenses” broadly. The obvious ones include doctor visits, hospital stays, surgeries, dental work (cleanings, fillings, braces, extractions), prescription medications, and vision care (eye exams, glasses, contacts, laser eye surgery). But the list goes well beyond routine care.
- Mental health and therapy: Psychiatric care, psychologist fees, psychoanalysis, and drug or alcohol addiction treatment all qualify.
- Reproductive health: Birth control pills (when prescribed), fertility treatments, pregnancy test kits, and breast pumps and supplies.
- Mobility and assistive devices: Wheelchairs, crutches, artificial limbs, hearing aids, guide dogs and other service animals.
- Home modifications for medical needs: Ramps, widened doorways, and other capital improvements that accommodate a disability or medical condition.
- Alternative care: Acupuncture, chiropractic adjustments, and osteopath fees.
- Over-the-counter items: Bandages, blood sugar test kits, contact lens solution, condoms, and personal protective equipment like masks and hand sanitizer.
- Other: Ambulance services, medical transportation costs, stop-smoking programs, special education tuition for learning disabilities, and even lodging when traveling for medical care (up to $50 per night per person).
One important limit: nonprescription drugs (other than insulin) generally don’t qualify unless a doctor prescribes them. So a bottle of ibuprofen you grab off the shelf isn’t an eligible expense on its own, but the same medication with a prescription would be.
Investing Your HSA Balance
Most HSA providers let you invest your balance in mutual funds or other options once you hit a minimum cash threshold. That threshold varies by provider but typically falls between $1 and $1,000. Any cash above that amount can be moved into an investment account within your HSA, where it grows tax-free.
This is where the HSA becomes more than a medical spending account. Contributions are tax-deductible (or pre-tax if made through payroll), the investments grow without being taxed, and withdrawals for qualified expenses are tax-free. No other account in the tax code offers all three benefits. For 2026, you can contribute up to $4,400 with self-only coverage or $8,750 with family coverage. If you’re 55 or older, you can add an extra $1,000 per year as a catch-up contribution.
If you can afford to pay medical bills out of pocket and leave your HSA invested, even a few years of compounding can make a meaningful difference. Someone contributing the family maximum and earning average market returns could accumulate a six-figure balance over a couple of decades.
The Receipt Strategy for Long-Term Growth
Here’s the detail most people miss: the IRS sets no deadline for HSA reimbursements. If you pay for a qualifying expense today out of your own pocket, you can reimburse yourself from your HSA tomorrow, next year, or 30 years from now. The only requirement is that you keep the receipt.
This creates a powerful strategy sometimes called the “shoebox” approach. Instead of swiping your HSA debit card at the pharmacy, you pay with a regular credit card (earning points in the process), then save the receipt digitally. Meanwhile, you max out your HSA contributions and invest the full balance. Years later, when you want tax-free cash for any reason, you pull out your old receipts and reimburse yourself. The withdrawal is completely tax-free because it’s reimbursement for a qualified medical expense, even though the expense happened years ago.
The key is organized recordkeeping. Save digital copies of every receipt, explanation of benefits statement, and pharmacy printout. A dedicated folder on your computer or a receipt-scanning app works well. If the IRS ever questions a withdrawal, you need to show that a qualifying expense occurred while you had the HSA and that you hadn’t already been reimbursed for it.
Using Your HSA After Age 65
Before you turn 65, any withdrawal that isn’t for a qualified medical expense gets hit with income tax plus a 20% penalty. That’s steep enough to make non-medical withdrawals a bad idea for most people.
After 65, the penalty disappears entirely. You can withdraw money for any purpose, whether it’s medical or not. If the withdrawal is for a qualified medical expense, it’s still completely tax-free. If it’s for something else, like general retirement spending, you’ll owe ordinary income tax on the amount, similar to how a traditional IRA or 401(k) withdrawal works. You won’t owe the 20% penalty regardless of what you spend it on.
This makes the HSA a flexible retirement tool. In a best-case scenario, you accumulate decades of medical receipts and can pull out large sums tax-free whenever you choose. In a worst case, you treat it like a traditional retirement account and pay income tax on non-medical withdrawals after 65. Either way, you’ve benefited from years of tax-free growth.
Practical Tips for Getting Started
If you’re new to your HSA, start by setting up your online account and linking a bank account for transfers. Order your debit card if your provider hasn’t already sent one. Check whether your provider offers investment options and what the minimum balance requirement is before you can start investing.
Decide on your approach: are you going to use your HSA as a spending account for current medical costs, or are you in a financial position to pay expenses out of pocket and let the HSA grow? You don’t have to pick one exclusively. Many people use the debit card for large expenses they can’t easily cover and pay smaller bills out of pocket while saving those receipts for future reimbursement.
If you’re investing, choose low-cost index funds when available. Your HSA is a long-term account, especially if you’re years away from 65, and keeping fees low matters over decades. Review your provider’s fund options the same way you’d review a 401(k) lineup, focusing on expense ratios and broad diversification.
