How an HSA actually works once you have one

An HSA (Health Savings Account) is a bank account that holds money specifically for medical expenses. You put money in (usually through payroll deductions), the money grows tax-free, and you withdraw it to pay for may have access to medical costs. The account stays yours even if you change jobs or health plans — unlike a Flexible Spending Account, which you lose at the end of the year.

The mechanics are straightforward: your employer or you deposits money, the account earns interest or investment returns, and you spend it on things like doctor visits, prescriptions, dental work, and medical equipment. You keep receipts and can withdraw money anytime. The tax benefit comes because the money going in is not taxed, the growth is not taxed, and withdrawals for medical expenses are not taxed.

Most HSAs come with a debit card, a checkbook, or online access to request reimbursement. Some people use the card at the pharmacy or doctor's office directly. Others pay out of pocket and then request the HSA reimburse them later — sometimes months or years later, as long as you have the receipt.

Key Takeaways

  • You can spend HSA money on may have access to medical expenses like copays, prescriptions, dental work, vision care, and medical equipment without paying taxes on the withdrawal.
  • Most HSAs come with a debit card or online portal, and you can request reimbursement for expenses you paid yourself if you have a receipt.
  • Money left in your HSA at the end of the year rolls over to the next year — you never lose it like you would with a Flexible Spending Account.
  • If you withdraw money for something that is not a may have access to medical expense, you pay income tax on that amount plus a 20 percent penalty.
  • You can invest HSA money in stocks, bonds, or mutual funds once your balance reaches a certain threshold, usually $1,000 to $2,500 depending on your provider.

What counts as a may have access to medical expense

The IRS has a specific list of what you can pay for with HSA money tax-free. The broad categories are doctor visits, hospital stays, prescription medications, dental care, vision care, and medical equipment or supplies. This includes copays, coinsurance, and deductibles — essentially anything your health insurance does not cover.

Common expenses that may have access to: prescription eyeglasses and contact lenses, dental cleanings and fillings, hearing aids, crutches, blood pressure monitors, and over-the-counter medications like ibuprofen or allergy pills (though you need a prescription for those as of 2020). Physical therapy, mental health counseling, and substance abuse treatment also count. Fertility treatments, including IVF, are covered.

Things that do not may have access to: cosmetic procedures (unless medically necessary), gym memberships, vitamins (unless prescribed by a doctor for a specific condition), and general wellness products. Health insurance premiums do not count, except for COBRA continuation coverage, long-term care insurance, or health coverage while you are unemployed and receiving unemployment benefits.

When in doubt, check your HSA provider's website or the IRS Publication 502, which lists may have access to expenses in detail. Some providers have a tool where you can search a specific item.

How to access and spend your HSA money

Most HSA providers give you a debit card that works like any other bank card. You can use it at pharmacies, doctor's offices, hospitals, and medical supply stores. The transaction posts to your HSA account, and the money is gone. This is the simplest method if you know the expense is may have access to.

If you do not have a debit card or prefer not to use it, you can pay for the medical expense yourself and then request reimbursement. Log into your HSA provider's website or app, upload a photo of the receipt, and request a transfer to your bank account. Most providers process this within a few business days. You can do this months or even years after the expense — the IRS does not set a time limit as long as you have the receipt and the expense happened after you opened the account.

Some HSA providers let you set up automatic bill pay to send money directly to your doctor or pharmacy. Others allow you to write checks from the account. Check what your specific provider offers when you open the account or log in for the first time.

Keep all receipts and documentation. If the IRS ever audits your HSA, you need to show that the money went to may have access to expenses. A receipt with the date, provider name, and what was purchased is usually enough.

Rolling over unused money and long-term growth

Unlike a Flexible Spending Account, an HSA has no "use it or lose it" rule. Money you do not spend in one year stays in the account and carries over to the next year. This means you can build a balance over time and use it for future medical expenses — or even save it for retirement.

Many people treat an HSA as a retirement savings tool. Once you turn 65, you can withdraw money for any reason without penalty (though you pay income tax on non-medical withdrawals). Before 65, non-medical withdrawals trigger a 20 percent penalty plus income tax, so most people save their HSA for actual medical expenses.

If your HSA balance reaches a certain threshold — usually $1,000 to $2,500 depending on your provider — you can invest the money in stocks, bonds, mutual funds, or other securities. This lets your HSA grow faster than it would sitting in a savings account. The investment gains are also tax-free as long as you use the money for medical expenses.

What happens if you use HSA money for non-medical expenses

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. You also pay a 20 percent penalty on top of the tax. For example, if you withdraw $500 for a non-medical expense and you are in the 22 percent tax bracket, you owe $110 in taxes plus a $100 penalty — a total of $210.

The penalty does not apply after age 65. Once you turn 65, you can withdraw HSA money for any reason and only pay income tax on non-medical withdrawals. This is one reason some people save their HSA for retirement rather than spending it all on current medical costs.

If you make a mistake — for example, you accidentally use the debit card for a non-medical purchase — contact your HSA provider right away. Some providers will reverse the transaction or let you correct it. The sooner you catch the error, the easier it is to fix.

Keeping track of your HSA across jobs and providers

Your HSA belongs to you, not your employer. If you leave your job, the account stays open and the money stays yours. You can keep it with the same provider or roll it over to a different HSA provider — the process is similar to rolling over a 401(k).

When you change jobs, check whether your new employer offers an HSA. If it does, you can roll your old HSA into the new one. If it does not, you can keep your old HSA open and continue using it for medical expenses. You just cannot make new contributions to it unless you are self-employed or have individual health insurance that qualifies.

Some people have multiple HSAs from different employers or providers. This is allowed, but your total contributions across all accounts cannot exceed the annual limit set by the IRS (which varies by year and whether you have individual or family coverage). Track all your accounts so you do not over-contribute by accident.

Common mistakes to avoid

The most common mistake is using your HSA debit card for something you think is medical but is not — like a gym membership or a vitamin that does not have a prescription. The transaction goes through, but you owe the penalty and taxes when you file your return.

Another mistake is losing track of receipts. The IRS does not require you to submit receipts when you file your taxes, but you need them if you are audited. Keep receipts for at least three to seven years, depending on your tax situation.

A third mistake is over-contributing. If you contribute more than the annual limit across all your HSAs, you owe a 6 percent excise tax on the excess amount each year until you correct it. Check the IRS limit for your coverage type (individual or family) before you contribute.

Finally, do not assume your HSA provider will catch errors. It is your responsibility to track contributions, withdrawals, and may have access to expenses. Review your account statements regularly and report any problems to your provider.
