A Health Savings Account (HSA) is a tax-advantaged account that lets you set aside money specifically for medical expenses. You contribute pre-tax dollars, the balance grows tax-free, and withdrawals for qualified medical costs are also tax-free. That triple tax benefit makes HSAs one of the most powerful savings tools available, but you need a specific type of health insurance plan to open one.
Who Can Open an HSA
To be eligible, you must be enrolled in a high-deductible health plan (HDHP). For 2026, that means your plan’s annual deductible is at least $1,700 for self-only coverage or $3,400 for family coverage. Your plan must also cap out-of-pocket expenses (deductibles, copays, and coinsurance, but not premiums) at no more than $8,500 for an individual or $17,000 for a family.
Beyond the plan requirement, you can’t be enrolled in Medicare, claimed as a dependent on someone else’s tax return, or covered by a non-HDHP health plan (like a spouse’s traditional insurance that covers you). If you meet all these criteria, you can open an HSA through your employer or independently at a bank, credit union, or brokerage that offers them.
How Much You Can Contribute
For 2026, the IRS allows you to 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. These limits include everything that goes into the account: your contributions, your employer’s contributions, and any other deposits.
If your employer contributes to your HSA, that money counts toward your annual cap. So if your employer puts in $1,000 and you have self-only coverage, you can contribute up to $3,400 yourself. Many employers do contribute as an incentive for choosing the high-deductible plan option, so check your benefits summary before maxing out your own deposits.
The Triple Tax Advantage
HSAs offer three layers of tax savings that no other account type matches.
First, contributions reduce your taxable income. If you contribute through payroll deductions, the money comes out before federal income tax and FICA taxes are calculated. If you contribute on your own, you deduct the amount on your tax return. Second, any interest or investment gains inside the account grow without being taxed. Third, when you withdraw money for qualified medical expenses, you pay zero tax on the distribution.
One caveat: a couple of states do not recognize HSA tax benefits at the state level. If you live in one of those states, your contributions will be treated as taxable income on your state return, and any employer contributions will show up as imputed income. Your federal tax benefits still apply in full.
What You Can Spend HSA Money On
The IRS defines qualified medical expenses broadly. You can use your HSA for doctor visits, surgery, dental work, vision care, mental health services, prescription medications, insulin, and chiropractic care. Medical equipment like crutches, wheelchairs, blood sugar test kits, and hearing aids also qualifies. So do fertility treatments, birth control pills, and stop-smoking programs.
Less obvious qualified expenses include transportation costs to get medical care (mileage, bus fare, ambulance fees), lodging up to $50 per night when traveling for treatment, home modifications to accommodate a disability, and premiums for qualified long-term care insurance. Once you’re on Medicare, you can use HSA funds to pay Medicare Part B and Part D premiums.
What doesn’t qualify: gym memberships, cosmetic procedures (unless correcting a deformity from injury or disease), vitamins and supplements, teeth whitening, over-the-counter drugs that aren’t prescribed (except insulin), and general wellness items like toothpaste. If you use HSA funds on non-qualified expenses before age 65, you’ll owe income tax on the amount plus a steep 20% penalty.
How Withdrawals Work Before and After 65
At any age, withdrawals for qualified medical expenses are completely tax-free. You simply pay with your HSA debit card at the point of sale, or reimburse yourself after paying out of pocket. Keep your receipts. The IRS can ask you to prove that a distribution was for a qualified expense, and there’s no time limit on when they might ask.
If you withdraw money for something other than medical care before you turn 65, you’ll pay regular income tax on that amount plus the 20% penalty. On a $1,000 non-medical withdrawal, someone in the 22% tax bracket would lose $420 to taxes and penalties.
After age 65, the penalty disappears. You can withdraw HSA funds for any reason and only pay ordinary income tax on non-medical distributions, similar to how a traditional IRA works. Medical withdrawals remain completely tax-free even after 65, so there’s still an advantage to using the money for healthcare.
Using Your HSA as a Long-Term Savings Tool
Unlike a flexible spending account (FSA), your HSA balance rolls over every year. There’s no “use it or lose it” deadline. The money stays in your account indefinitely, even if you change jobs or switch to a non-HDHP plan. You just can’t make new contributions while you’re on a non-qualifying plan.
Many HSA providers let you invest your balance in mutual funds, index funds, or other options once you hit a minimum cash threshold (often $1,000 or $2,000). This turns the HSA into a long-term investment vehicle. Because contributions, growth, and qualified withdrawals are all tax-free, some people intentionally pay current medical bills out of pocket and let their HSA balance grow for decades. You can reimburse yourself for those out-of-pocket costs at any point in the future, as long as you have documentation showing the expense occurred after you opened the account.
This strategy works especially well for younger, healthy individuals who don’t have major medical costs yet. A $4,400 annual contribution invested over 20 or 30 years can grow into a significant medical fund for retirement, when healthcare expenses tend to be highest.
How to Open and Manage an HSA
If your employer offers an HSA alongside its high-deductible plan, enrolling during open enrollment is the easiest route. Payroll deductions are set up automatically, and you get the additional benefit of avoiding FICA taxes on contributions. Some employers also match or seed the account with their own contributions.
You can also open an HSA independently at banks, credit unions, or investment brokerages. Compare providers based on monthly fees (some charge $2 to $5 per month, while others waive fees entirely), investment options, and the minimum balance required before you can invest. Once open, you contribute directly and claim the tax deduction when you file your return.
Your HSA belongs to you. If you leave your job, the account and its full balance go with you. You can transfer or roll over your HSA to a different provider at any time without tax consequences, which is worth doing if your employer’s default provider charges high fees or offers limited investment choices.
