To get a health savings account (HSA), you need two things: enrollment in an HSA-eligible high-deductible health plan (HDHP) and an HSA opened through your employer’s benefits program or directly with a financial institution. The process takes minutes once you confirm you qualify, but eligibility rules trip up a lot of people. Here’s how to make sure you can open one and what to do next.
Check Whether You’re Eligible
An HSA isn’t available to everyone with health insurance. You must be covered under a specific type of plan called a high-deductible health plan. For 2026, the IRS defines that as a plan with an annual deductible of at least $1,700 for self-only coverage or $3,400 for family coverage. The plan must also cap your out-of-pocket expenses (excluding premiums) at no more than $8,500 for self-only coverage or $17,000 for family coverage.
Beyond the plan itself, you must meet all four of these conditions:
- You’re covered under an HDHP on the first day of the month you want to contribute.
- You have no disqualifying health coverage (more on this below).
- You aren’t enrolled in Medicare.
- You can’t be claimed as a dependent on someone else’s tax return.
If your employer offers a health plan, the enrollment materials will usually indicate whether it’s “HSA-eligible” or “HSA-compatible.” Not every HDHP qualifies, so look for that specific label rather than assuming a high deductible alone is enough.
Coverage That Can Disqualify You
Having a second health plan alongside your HDHP will generally make you ineligible for an HSA. The most common issue is a general-purpose flexible spending account (FSA) or health reimbursement arrangement (HRA). If either of those can reimburse medical expenses before your HDHP deductible is met, you cannot contribute to an HSA.
There are workarounds. A “limited-purpose” FSA or HRA that only covers dental, vision, and preventive care won’t disqualify you. Neither will a “post-deductible” FSA or HRA that kicks in only after you’ve met the HDHP’s minimum deductible. If your employer offers both an HDHP and an FSA, ask your benefits team which type of FSA it is before enrolling.
You can also keep coverage for accidents, disability, dental, vision, long-term care, and workers’ compensation without losing HSA eligibility. A separate prescription drug plan is fine too, as long as it doesn’t pay benefits until the HDHP deductible has been met. Medicare enrollment of any kind, including Part A, disqualifies you entirely.
Open an HSA Through Your Employer
The simplest path is through your workplace. If your employer offers an HDHP, they often partner with an HSA provider and let you enroll during open enrollment or when you first become eligible. The signup process typically takes five minutes or less online.
The main advantage of an employer-sponsored HSA is payroll deductions. Your contributions come out of your paycheck before federal income tax and before Social Security and Medicare taxes are calculated. That extra layer of tax savings, the payroll tax reduction, is something you can’t replicate when contributing on your own. Your employer may also make contributions to your HSA as a benefit, essentially giving you free money toward medical expenses.
One thing to know: even though your employer sets up the HSA, the account belongs to you. If you leave the job, the money goes with you. You can transfer or roll the balance to a different provider anytime.
Open an HSA on Your Own
You don’t need an employer to get an HSA. If you’re self-employed, work for a company that doesn’t offer one, or simply prefer a different provider than the one your employer chose, you can open an account directly with a bank, credit union, or investment firm that offers HSAs.
The process looks like opening any other financial account. You’ll provide your name, address, Social Security number, and information about your HDHP. Most providers let you complete the application online in a few minutes. Once the account is open, you fund it through bank transfers. You won’t get the payroll tax benefit this way, but you can still deduct your contributions on your tax return, which reduces your federal income tax.
If your employer does offer an HSA through a specific provider, you can still open a separate HSA elsewhere. Some people do this to access better investment options. You can even ask your employer to split payroll deductions into the account of your choice by providing your account number.
How Much You Can Contribute
For 2026, the IRS allows a maximum contribution of $4,400 for self-only HDHP coverage and $8,750 for family coverage. These limits include everything: your contributions, your employer’s contributions, and any other deposits. Going over triggers a 6% excise tax on the excess for every year it stays in the account.
If you’re 55 or older, you can contribute an extra $1,000 per year as a catch-up contribution. This amount has been fixed at $1,000 by statute and doesn’t adjust for inflation.
You have until your tax filing deadline (typically April 15 of the following year) to make contributions for a given tax year. So if you open an HSA partway through the year, you can still make a lump-sum deposit to cover earlier months, though special proration rules may apply if you weren’t covered by an HDHP for the full year.
Choosing a Provider
If you’re picking your own HSA provider, focus on three things: fees, investment options, and minimum balance requirements.
Some providers charge no monthly or annual account fees. Others charge around $24 to $48 per year, sometimes waiving the fee if your balance is above a certain threshold. Zero-fee providers exist, so there’s little reason to pay for basic account maintenance unless the provider offers something else you value.
Investment options matter if you plan to use your HSA as a long-term savings vehicle rather than spending it down each year. Most providers require a minimum cash balance, typically $500 to $2,000, before you can invest. Only the amount above that threshold goes into investments. A few providers, like Fidelity, have no minimum balance requirement for investing, letting you put every dollar to work from the start. Available investment choices range from mutual funds and ETFs to individual stocks and bonds, depending on the provider.
If your employer’s HSA provider charges high fees or offers limited investment choices, remember you can periodically transfer your balance to a different provider. There’s no limit on how many HSA transfers you can do, though some providers charge a transfer-out fee, so check before you move money.
The Triple Tax Advantage
An HSA is the only account in the tax code that offers a tax break at three stages. Contributions are tax-deductible (or pre-tax through payroll). The money grows tax-free through interest or investment gains. And withdrawals are tax-free when used for qualified medical expenses, which include doctor visits, prescriptions, dental work, vision care, and hundreds of other costs.
If you withdraw money for something other than a qualified medical expense before age 65, you’ll owe income tax plus a 20% penalty. After 65, non-medical withdrawals are taxed as ordinary income but carry no penalty, making the account function similarly to a traditional retirement account at that point.
Unlike a flexible spending account, there’s no “use it or lose it” deadline. Your HSA balance rolls over every year and stays yours indefinitely, even if you change jobs, switch health plans, or retire. This rollover feature is what makes the HSA work as both a short-term medical spending tool and a long-term savings account.
