Opening a health savings account (HSA) takes about 15 minutes online, either through your employer or directly with an HSA provider like Fidelity or Lively. The bigger question is whether you qualify, which depends entirely on the type of health insurance you carry. Here’s what you need to know before you start, and exactly how the process works.
Check Your Eligibility First
You can only open and contribute to an HSA if you’re enrolled in a high-deductible health plan (HDHP). For 2026, that means your plan’s deductible is at least $1,700 for self-only coverage or $3,400 for family coverage. Your plan’s out-of-pocket maximum also can’t exceed $8,500 (self-only) or $17,000 (family). These thresholds are set by the IRS and adjust each year.
Beyond the health plan requirement, you also can’t be enrolled in Medicare, claimed as a dependent on someone else’s tax return, or covered by a non-HDHP plan (like a spouse’s traditional health insurance that covers you). If your spouse has a general-purpose flexible spending account (FSA) that could reimburse your expenses, that can also disqualify you. A limited-purpose FSA restricted to dental and vision is fine.
Decide Where to Open Your Account
You have two paths: open an HSA through your employer’s benefits program, or open one on your own with any provider that offers individual HSAs.
If your employer offers an HSA alongside its high-deductible plan, that’s usually the easiest route. Your contributions come out of your paycheck before taxes, which means you skip not just income tax but also Social Security and Medicare taxes on those dollars. Your employer handles the paperwork, and some employers even contribute money to your HSA as a benefit.
If your employer doesn’t offer an HSA, or if you’re self-employed, you can open one independently. Fidelity is a popular choice because it charges no account management fees and has no minimum balance to start investing. Other providers like Lively also offer individual accounts, though fee structures vary. When comparing providers, look at three things: monthly or annual account fees, the investment options available once your balance grows, and whether the provider charges you to transfer your money out later.
What You Need to Apply
The application is straightforward. Have these ready before you start:
- Social Security number or tax identification number
- Government-issued ID such as a driver’s license or passport for identity verification
- Bank account details (routing and account numbers) if you plan to fund the HSA with a transfer from your checking or savings account
- Beneficiary information including names, addresses, birthdates, and Social Security numbers for anyone you want to designate
If you’re opening through an employer, you typically won’t need to provide bank account details since contributions flow through payroll. Some providers also ask for basic employment information, especially if you’re a new customer at that financial institution.
Know Your Contribution Limits
For 2026, you can contribute up to $4,400 if you have self-only coverage, or up to $8,750 for family coverage. If you’re 55 or older, you can contribute an extra $1,000 per year on top of those limits as a catch-up contribution.
These limits include everything that goes into your HSA: your own contributions, your employer’s contributions, and contributions anyone else makes on your behalf. If your employer puts in $1,000 toward your self-only HSA, you can add up to $3,400 more yourself.
You don’t have to contribute the full amount all at once. You can set up automatic transfers throughout the year or make lump-sum deposits whenever you have extra cash. You even have until the tax filing deadline (typically April 15 of the following year) to make contributions that count toward the prior year.
How to Fund Your HSA
If your HSA is through your employer, contributions are deducted from your paycheck pre-tax. You choose a per-paycheck amount during benefits enrollment, and the money flows in automatically.
If you opened your HSA independently, you’ll fund it with after-tax dollars, typically by transferring money from a bank account. The good news is you still get the tax break. You claim the deduction when you file your taxes by completing Form 8889 and attaching it to your return. The deduction reduces your taxable income even if you don’t itemize, which makes it one of the more valuable “above the line” deductions available.
The one difference between employer and individual contributions is payroll taxes. Employer-based pre-tax contributions avoid Social Security and Medicare taxes (a combined 7.65% savings). Individual contributions you deduct on your tax return reduce your income tax but don’t reduce those payroll taxes.
Using and Investing Your HSA
Most HSA providers give you a debit card linked to your account so you can pay for qualified medical expenses directly. Eligible expenses include doctor visits, prescriptions, dental work, vision care, and a long list of other health-related costs. If you pay out of pocket instead, you can reimburse yourself from the HSA later, and there’s no deadline for doing so.
One of the most powerful features of an HSA is that it doubles as an investment account. Once your balance reaches a comfortable level for near-term medical costs, you can invest the rest in mutual funds, index funds, or other options your provider offers. Fidelity, for instance, lets you start investing with no minimum balance. Investment growth inside an HSA is tax-free, and withdrawals for qualified medical expenses are also tax-free, giving you a rare triple tax advantage: deductible going in, tax-free growth, and tax-free coming out.
Unlike a flexible spending account, your HSA balance rolls over every year. There’s no “use it or lose it” rule. The money is yours permanently, even if you change jobs or switch health plans. If you later move to a non-HDHP plan, you can still spend the money already in your HSA on qualified expenses. You just can’t make new contributions until you’re back on a qualifying plan.
What Happens If You Withdraw for Non-Medical Expenses
If you pull money from your HSA for something other than a qualified medical expense, you’ll owe income tax on the withdrawal plus a 20% penalty. That penalty disappears once you turn 65, at which point your HSA essentially works like a traditional retirement account for non-medical spending (you’ll still owe income tax, just no penalty). For medical expenses, withdrawals remain completely tax-free at any age.
