The Basic Requirements for an HSA

To open a Health Savings Account, you need three things: you must be enrolled in a high-deductible health plan (HDHP), you cannot be covered by other health insurance that isn't an HDHP, and you cannot be claimed as a dependent on someone else's tax return. That's the core of it. If all three are true, you can open an HSA.

The "high-deductible" part is the key gate. Your health plan must have a deductible of at least $1,600 for individual coverage or $3,200 for family coverage in 2024. These numbers change each year, so check with your plan or the IRS website for the current year's limits. Your plan also has a maximum out-of-pocket limit — the most you'd pay in a year before insurance covers everything — and that limit matters too, but the deductible is what determines whether you're may be able to access.

You don't have to choose an HDHP. Many employers offer standard health plans with lower deductibles, and those plans don't may have access to. If your employer offers both types, you get to pick which one to enroll in. If you buy insurance on your own through the marketplace, you can search for plans labeled as HSA-compatible or HSA-may be able to access.

Key Takeaways

  • You must be enrolled in a high-deductible health plan with a deductible of at least $1,600 (individual) or $3,200 (family) in 2024 to open an HSA.
  • You cannot have other health insurance at the same time, except for specific plans like dental-only or vision-only coverage.
  • You cannot be claimed as a dependent on someone else's tax return, even if you have your own income.
  • Your employer may offer an HSA through payroll, or you can open one independently through a bank or financial institution.
  • Once you stop being covered by an HDHP, you can no longer contribute to an HSA, but you keep the money that's already there.

What "Other Health Insurance" Actually Means

The rule sounds straightforward — you can't have other health insurance — but it has real exceptions. You can have dental-only coverage, vision-only coverage, or accident-only insurance at the same time as your HDHP. You can also have coverage for specific conditions like cancer or hospitalization. What you cannot have is another plan that covers general medical care, whether that's a standard PPO, an HMO, Medicare, Medicaid, or TRICARE.

If you're married and your spouse has a standard health plan, you cannot open an HSA. Both of you would need to be on an HDHP for both to be may be able to access. If you're on your parent's plan and it's not an HDHP, you're not may be able to access. If you're on Medicare, you cannot contribute to an HSA, though you can keep one you opened before turning 65.

The dependent rule is separate and strict. If someone else claims you as a dependent on their tax return — even if you pay for your own health insurance — you cannot open an HSA. This affects many people in their early twenties whose parents still claim them, and it's a common surprise.

How Your Employer's Plan Affects Your Options

If your employer offers an HDHP, they usually offer an HSA as well, often through payroll deduction. This is the easiest route because your employer handles the setup and your contributions come straight from your paycheck before taxes. You don't have to do anything except enroll during open enrollment or when you're first hired.

Some employers contribute money to your HSA as part of your benefits package. This is information programs — you don't have to contribute anything yourself to open the account. Even if your employer doesn't contribute, you can still open an HSA and add your own money.

If your employer doesn't offer an HSA, or if you buy insurance on your own, you can open an HSA independently through a bank, credit union, or investment firm. You'll need to show proof that you're enrolled in an HDHP — usually a copy of your insurance card or enrollment confirmation. The process takes a few days to a week.

Age and Citizenship Requirements

You must be a U.S. citizen or resident alien to open an HSA. You also cannot be enrolled in Medicare, even if you're still working. Once you turn 65, you become may be able to access for Medicare, and at that point you can no longer contribute new money to an HSA. The money already in the account stays there and you can still use it for medical expenses, but you cannot add more.

There's no minimum age to open an HSA — a parent can open one for a child if the child is covered by an HDHP. There's also no maximum age as long as you're not on Medicare.

What Happens If You Lose Your HDHP Coverage

Your HSA may be able to access is tied to your HDHP enrollment. If you switch to a standard health plan, you can no longer contribute to your HSA starting the month your coverage changes. The money already in the account is yours to keep and use for medical expenses whenever you need it, even years later. You just can't add new money.

If you leave your job and lose your employer's HDHP, you can open an HSA independently if you buy an HDHP on the marketplace. If you switch to a spouse's standard plan or enroll in Medicare, your contribution window closes but your account remains active.

Some people move in and out of HDHP coverage over their lifetime — working for an employer with an HDHP, then switching jobs to one without, then buying their own HDHP plan. Each time you're covered by an HDHP, you can contribute. Each time you're not, you can't. The account itself never expires.

Dependent Status and Tax Returns

The dependent rule is the one that catches people off guard. You cannot open an HSA if you're claimed as a dependent on someone else's tax return, even if you have your own job and pay for your own insurance. This applies whether you're 18 or 28, whether you live with that person or not, and whether they actually help pay for your care.

If you're in this situation, you have two paths: you can ask the person claiming you to stop, or you can wait until you're no longer claimed as a dependent. Many parents stop claiming adult children once they're working full-time, but some don't. If you're unsure whether you're being claimed, you can check your tax return or ask the person directly.

Once you're no longer claimed as a dependent and you're covered by an HDHP, you become may be able to access to open an HSA. There's no waiting period — you can open one the same month your dependent status ends.

Opening an HSA After You Confirm may be able to access

Once you've confirmed you meet all the requirements, opening an account is straightforward. If your employer offers one, you enroll during open enrollment or when hired, and they handle the rest. If you're opening one independently, you'll contact a bank, credit union, or investment company that offers HSAs. You'll need your Social Security number, proof of HDHP enrollment (your insurance card or a letter from your plan), and basic information like your address and employment status.

Some institutions charge monthly fees for HSAs, while others don't. Some offer investment options for money you're not using when ready, while others keep it in a savings account. Compare a few before choosing — the account is yours to manage, and you can switch providers later if you want to.

After you open the account, you can start contributing when ready. If you're contributing through payroll, your employer will deduct the money and deposit it into your HSA. If you're contributing on your own, you can set up automatic transfers from your bank account or make one-time deposits.

Check your insurance card or the plan documents your employer gave you. Look for the deductible amount — if it's at least $1,600 for individual coverage or $3,200 for family coverage in 2024, it qualifies. You can also call your insurance company or ask your employer's benefits department.

Can I open an HSA after I've already enrolled in my HDHP?

Yes. You don't have to open an HSA when you enroll in the HDHP. You can open one anytime you're covered by an HDHP and meet the other requirements. However, you can only contribute for the months you were actually covered by the HDHP, so opening sooner rather than later lets you contribute for more of the year.
