How to use an HSA: the basic steps
A Health Savings Account works like a bank account that holds money specifically for medical costs. You put money in (usually through payroll deduction), the money grows tax-free, and you withdraw it to pay for may have access to medical expenses—doctor visits, prescriptions, dental work, vision care, and many other health costs. The account stays yours even if you change jobs or retire.
To use your HSA, you need three things: a high-deductible health plan (HDHP), an HSA opened with a bank or financial institution, and knowledge of which expenses may have access to. Most employers that offer HSAs set them up automatically, but if you have an HDHP through the individual market, you open an HSA yourself at a bank, credit union, or investment firm.
Once the account is open, you can fund it in three ways: through payroll deduction (the most common), by depositing money yourself, or by rolling over funds from another HSA. You then use the money by paying out of pocket for a may have access to expense and either reimbursing yourself from the HSA or paying the provider directly from your HSA debit card or checkbook.
Key Takeaways
- You can withdraw HSA money for any may have access to medical expense without penalty, and the withdrawal is not taxed.
- Common may have access to expenses include copays, deductibles, prescriptions, dental and vision care, mental health treatment, and medical equipment like hearing aids and wheelchairs.
- You do not have to spend HSA money in the year you contribute it—unused funds roll over and grow tax-free indefinitely.
- Withdrawals for non-medical expenses before age 65 are taxed as income plus a 20 percent penalty; after 65, they are taxed as income only.
- Keep receipts for all HSA withdrawals in case the IRS asks you to prove the expense was may have access to.
Which medical expenses you can pay for with an HSA
The IRS maintains a list of may have access to medical expenses, and it is longer than most people realize. The obvious ones are doctor visits, hospital stays, surgery, and prescription medications. But the list also includes dental work (fillings, root canals, orthodontia), vision care (eye exams, glasses, contact lenses), hearing aids, mental health counseling, physical therapy, and medical equipment like crutches, wheelchairs, and blood pressure monitors.
Some expenses that sound medical do not may have access to. Over-the-counter pain relievers, cold medicine, and vitamins do not count unless a doctor prescribes them specifically. Cosmetic procedures do not may have access to unless they treat an injury or illness—reconstructive surgery after an accident counts, but a facelift does not. Gym memberships and general wellness programs do not may have access to, though treatment for a specific condition (like physical therapy for a knee injury) does.
Long-term care insurance premiums may have access to, as do certain expenses for a spouse or dependent, even if they are not on your health plan. If you are unsure whether a specific expense qualifies, ask your HSA provider or check IRS Publication 502, which lists hundreds of may have access to and non-may have access to expenses by category.
How to withdraw money and pay for expenses
Most HSAs come with a debit card that works like a regular bank card. You can swipe it at a pharmacy, doctor's office, or hospital to pay for a may have access to expense directly. The money comes out of your HSA balance immediately. This is the simplest method and requires no paperwork at the time of purchase.
If you do not have a debit card or prefer not to use it, you can pay out of pocket with your regular bank account or credit card, then request a reimbursement from your HSA. You submit a claim (usually online through your HSA provider's website) with a receipt or explanation of benefits showing the date, provider, and amount. The HSA provider transfers the money to your bank account within a few business days.
A third option is to write a check directly from your HSA if your provider offers a checkbook. This is less common but works the same way as a debit card—the money comes out of the HSA balance when the check clears.
Keep all receipts and explanations of benefits for at least three years. The IRS can audit HSA withdrawals and ask you to prove that an expense was may have access to. If you cannot show documentation, the withdrawal may be treated as non-medical and subject to income tax plus a 20 percent penalty.
What happens to money you do not spend
Unlike a flexible spending account (FSA), an HSA does not have a "use it or lose it" rule. Any money you do not spend in a given year rolls over to the next year and stays in the account indefinitely. The balance grows tax-free, which means you can let it accumulate over many years if you do not need it right away.
Some people use this feature strategically: they pay for small medical expenses out of pocket and leave the HSA untouched, letting it grow like an investment account. This works especially well if you are healthy, have a low deductible relative to your income, and can afford to pay for routine care without touching the HSA. By retirement, the account can become a significant source of tax-assistance programs for medical expenses in later life.
If you change jobs or lose your HDHP coverage, you keep the HSA and the money in it. You can continue to withdraw for may have access to medical expenses even if you are no longer enrolled in an HDHP, though you cannot make new contributions once you lose HDHP coverage.
Penalties and taxes for non-may have access to withdrawals
If you withdraw money from your HSA for something that is not a may have access to medical expense before age 65, you owe income tax on the withdrawal plus a 20 percent penalty. For example, if you withdraw $500 for a non-may have access to expense and your tax bracket is 22 percent, you owe $500 × 0.22 = $110 in income tax, plus $500 × 0.20 = $100 in penalty, for a total of $210 in taxes and penalties on a $500 withdrawal.
After age 65, the penalty goes away. You can withdraw money for any reason without the 20 percent penalty, though you still owe income tax on non-medical withdrawals. This makes an HSA similar to a traditional IRA in retirement—a tax-advantaged account that becomes more flexible once you reach 65.
If you accidentally withdraw money for a non-may have access to expense, you can sometimes correct it. If you realize the mistake within a short time, some HSA providers allow you to redeposit the money. Check with your provider about their correction policy.
How to track and manage your HSA
Most HSA providers offer an online portal or mobile app where you can see your balance, review past withdrawals, and submit reimbursement claims. Log in regularly to make sure the balance is correct and that all transactions match your records. Some providers also send quarterly or annual statements.
Keep a personal record of medical expenses separate from your HSA provider's records. A simple spreadsheet with the date, provider, expense type, amount, and whether you paid from the HSA or out of pocket helps you track what you have spent and what you still have available. This is especially useful if you have a family HSA and multiple people are using it.
If your HSA provider offers investment options (many do), you can invest the money in mutual funds or other securities rather than keeping it in a cash account. This allows the balance to grow faster, though it also carries investment risk. Some people invest HSA money they do not plan to use for several years and keep a smaller cash balance for immediate medical expenses.
HSA rules if you have a spouse or dependents
If you are married and both spouses have HSAs, each account is separate and has its own contribution limit. You cannot combine them or transfer money between them. Each spouse can withdraw from their own HSA for their own medical expenses or for the other spouse's or dependents' medical expenses.
If you have dependents, you can use your HSA to pay for their may have access to medical expenses even if they are not on your health plan. This includes children, parents, and other relatives you claim as dependents on your tax return. Keep documentation showing the relationship and the expense.
If you are divorced or separated, your HSA remains yours. You cannot use it to pay for an ex-spouse's medical expenses after the divorce is final, though you can continue to use it for your children's expenses if you claim them as dependents.
