To set up a health savings account (HSA), you need to be enrolled in a high-deductible health plan (HDHP), then open an HSA through a bank, credit union, or other financial institution. You can do this through your employer’s benefits program or independently on your own. The whole process takes about the same effort as opening a checking account, but there are eligibility rules, contribution limits, and provider differences worth understanding before you start.
Check Your Eligibility First
You can only contribute to an HSA if you’re covered by a qualifying high-deductible health plan. For 2026, that means your plan must have a minimum annual deductible of $1,700 for self-only coverage or $3,400 for family coverage. Your plan’s out-of-pocket maximum (the most you’d pay in a year for covered services, not counting premiums) can’t exceed $8,500 for self-only or $17,000 for family coverage.
Beyond the plan itself, you also can’t be enrolled in Medicare, claimed as a dependent on someone else’s tax return, or covered by another health plan that isn’t high-deductible. If your spouse has a traditional health plan through their employer that covers you, that generally disqualifies you from contributing to an HSA, even if your own plan meets the deductible threshold.
Through Your Employer or On Your Own
There are two paths to opening an HSA, and the one you choose affects how your contributions are taxed.
If your employer offers an HDHP with an HSA option, they’ll typically set up payroll deductions that go directly into your HSA before taxes are withheld. This is the better deal: contributions made through payroll deductions skip federal income tax, Social Security tax, and Medicare tax (FICA). That extra FICA savings, worth 7.65% of every dollar you contribute, is something you can’t get any other way. Your employer handles sending the money to the HSA custodian, and you can usually start, change, or stop contributions at any time during the year.
If your employer doesn’t offer an HSA option, or if you’re self-employed or buying your own HDHP through the marketplace, you can open an HSA independently at any financial institution that offers them. You’ll fund the account with after-tax dollars from your bank account, then claim a deduction when you file your taxes using Form 8889. You’ll get the income tax deduction, but you won’t avoid the FICA taxes the way payroll contributions do.
How to Open the Account
Opening an HSA is straightforward. If you’re going through your employer, they’ll direct you to their partnered HSA provider during benefits enrollment. You’ll fill out an application, provide basic personal information, and select your contribution amount per paycheck.
If you’re opening one independently, you have more choices. Start by searching for HSA providers online, checking whether your health insurance company partners with a specific institution, or asking your current bank if they offer HSAs. You’ll need to provide your name, address, Social Security number, and proof that you’re enrolled in a qualifying HDHP. Most providers let you complete the application online in 15 to 20 minutes.
Choosing the Right Provider
Not all HSA providers charge the same fees or offer the same features, so it pays to compare before you sign up.
Some providers charge monthly maintenance fees, typically a few dollars a month that add up over time. Others charge fees for paper statements, account closings, or excess contribution returns. A handful of providers, like Fidelity, charge no monthly maintenance fees at all on self-directed accounts. Lively, another popular option, charges $24 per year for account management, though that fee is sometimes waived through promotional links.
Beyond fees, look at practical banking features: whether the provider offers a debit card for medical expenses, mobile app access, and easy options for depositing money. If you plan to use your HSA primarily for current medical bills, convenient access matters most. If you want to invest the balance for long-term growth, the investment options matter more.
Investing Your HSA Balance
One of the most powerful features of an HSA is the ability to invest the funds, not just save them. Money in an HSA grows tax-free, and withdrawals for qualified medical expenses are also tax-free. That triple tax advantage (deductible going in, tax-free growth, tax-free withdrawals) makes HSAs one of the most efficient savings vehicles available.
Most providers require a minimum cash balance before you can start investing, typically between $500 and $2,000. Any amount above that threshold can be moved into mutual funds, index funds, or other investment options. Fidelity is an exception, requiring no minimum balance to begin investing. Some providers waive the minimum balance requirement if you pay an additional fee. When comparing providers, check what investment options are available and what expense ratios the funds charge, since those ongoing costs eat into your returns over time.
Contribution Limits
The IRS sets annual limits on how much you can put into an HSA. For 2026, the limit is $4,300 for self-only coverage and $8,550 for family coverage. If you’re 55 or older, you can contribute an extra $1,000 per year as a catch-up contribution.
These limits apply to the combined total of your contributions and any employer contributions. So if your employer puts $500 into your HSA, your own contributions for the year are reduced by that amount. You have until the tax filing deadline (typically April 15 of the following year) to make contributions that count toward the prior year’s limit, giving you extra time to max out if you want to.
If you contribute more than the limit, the excess is subject to a 6% penalty tax for each year it stays in the account. You can avoid this by withdrawing the excess amount (and any earnings on it) before you file your tax return for that year.
How HSA Taxes Work
If your contributions go in through payroll deductions, they’ll show up on your W-2 in box 12 with code W. You won’t need to claim a separate deduction for those, since they were already excluded from your taxable wages.
If you contribute on your own with after-tax money, you’ll attach Form 8889 to your tax return to claim the deduction. This is an “above the line” deduction, meaning you get it whether or not you itemize. Your HSA custodian will send you Form 5498-SA showing your total contributions for the year and Form 1099-SA reporting any distributions you took. Keep receipts for all medical expenses you pay from the account, since the IRS can ask you to prove that withdrawals were used for qualified expenses.
Withdrawals for non-medical expenses before age 65 are taxed as income and hit with a 20% penalty. After 65, non-medical withdrawals are taxed as ordinary income but the penalty goes away, making the account function similarly to a traditional IRA at that point.
What You Can Pay For With HSA Funds
Qualified medical expenses include doctor visits, prescriptions, dental care, vision care, lab work, mental health services, and many over-the-counter medications and health products. You can also use HSA funds for expenses that insurance rarely covers, like glasses, contact lenses, hearing aids, and certain first-aid supplies. The IRS publishes a detailed list in Publication 502, but the practical scope is broad enough that most out-of-pocket health spending qualifies.
You don’t have to spend your HSA funds in the year you contribute them. Unlike a flexible spending account (FSA), there’s no “use it or lose it” deadline. Your balance rolls over indefinitely, and the account stays yours even if you change jobs, switch insurance plans, or retire.
