Not everyone can open an HSA — you need a specific type of health insurance first

You can open a Health Savings Account only if you are enrolled in a High Deductible Health Plan (HDHP). That is the hard requirement. If your employer offers a standard PPO or HMO, or if you are on Medicare, Medicaid, or Tricare, you cannot open an HSA, no matter how much you want to save for medical expenses.

The IRS sets the rules, and they are strict about this pairing. An HDHP is not just any plan with a high deductible — it is a specific category of coverage that meets IRS minimums for deductible amounts and out-of-pocket limits. Your insurance company will tell you whether your plan qualifies. If it does, you become HSA-may be able to access, and you can then open an account at a bank, credit union, or investment firm.

The timing matters. You can open an HSA only during the months you are actually covered by an HDHP. If you switch to a different plan type mid-year, you lose HSA may be able to access when ready, though you keep the money already in the account.

Key Takeaways

  • You must be enrolled in an HDHP to open an HSA; standard health plans, Medicare, Medicaid, and Tricare do not may have access to.
  • Your insurance company confirms whether your specific plan meets IRS standards for HDHP status.
  • You can open an HSA at any bank, credit union, or brokerage that offers them — not just through your employer.
  • Self-employed people and those buying individual plans can open HSAs if their plan is an HDHP, even without employer sponsorship.
  • You lose HSA may be able to access the moment you switch away from an HDHP, but the money in your account stays yours.

What counts as an HDHP and who offers them

An HDHP must meet IRS deductible minimums that change each year. For 2024, a self-only HDHP must have a deductible of at least $1,600, and a family plan must have a deductible of at least $3,200. The out-of-pocket maximum — the most you pay before insurance covers everything — cannot exceed $8,050 for self-only or $16,100 for family coverage. These numbers shift annually.

Most HDHPs are offered by employers, but they are also sold on the individual market through healthcare.gov or state exchanges. If you buy your own insurance and choose an HDHP, you become HSA-may be able to access. Some insurers label their plans clearly as HSA-compatible; others require you to check the deductible and out-of-pocket limits against the current IRS thresholds.

Not all insurers offer HDHPs in all states. Availability depends on the insurer and your location. If your employer offers only traditional plans, or if you live in an area where no insurer sells HDHPs, you cannot open an HSA — the requirement is not optional.

Self-employed and individual plan holders

If you are self-employed or buy your own health insurance, you can open an HSA as long as your plan is an HDHP. You do not need an employer to sponsor the account. You can open it at any financial institution that offers HSAs — banks like Fidelity, Lively, or HealthEquity, or your own bank if they provide them.

The process is straightforward: you enroll in an HDHP, confirm with the insurer that it meets HDHP standards, then contact a financial institution and provide proof of your HDHP coverage. You will need your insurance policy number or a letter from your insurer stating that your plan qualifies.

Self-employed people often use HSAs as a tax-advantaged savings tool because contributions reduce taxable income and withdrawals for medical expenses are tax-free. The contribution limits are the same as for employees — $4,150 for self-only coverage and $8,300 for family coverage in 2024 — but you control the account entirely.

Who cannot open an HSA, even with an HDHP

If you are claimed as a dependent on someone else's tax return, you cannot open your own HSA, even if you have an HDHP. The IRS does not allow it. Your parent or guardian could open an HSA on your behalf if they are the account owner, but you cannot own it yourself.

If you are enrolled in Medicare, you lose HSA may be able to access the month you turn 65 and enroll, regardless of your plan type. You can keep the money in your HSA and withdraw it for any reason without penalty after 65 (though non-medical withdrawals are taxed as income), but you cannot make new contributions once Medicare starts.

Tricare beneficiaries and people on Medicaid cannot open HSAs because these programs are not HDHPs. Veterans using VA coverage also cannot open HSAs. If you have any of these coverages as your primary insurance, HSA may be able to access is closed to you.

Opening an HSA outside your employer's plan

You do not have to open an HSA through your employer, even if your employer offers one. You can open an account at any bank or investment firm that offers HSAs. Some people do this to get better investment options, lower fees, or straightforward to keep their HSA separate from their employer.

The only requirement is that you prove you are covered by an HDHP. Most financial institutions ask for a copy of your insurance card or a letter from your insurer confirming HDHP status. The process takes a few days to a week.

If your employer offers an HSA but you want to open one elsewhere, you can do both — but your total contributions across all accounts cannot exceed the annual IRS limit. If you contribute $2,000 through your employer's plan, you can contribute only $2,150 more to an outside account (assuming self-only coverage at 2024 limits). You are responsible for tracking the total.

What happens if you lose HDHP coverage

The moment you switch to a non-HDHP plan — whether through a job change, a plan switch during open enrollment, or aging into Medicare — you lose the right to make new HSA contributions. This happens when ready, not at the end of the month.

The money already in your HSA is yours forever. You can withdraw it for medical expenses at any time, tax-free. If you withdraw it for non-medical reasons, you pay income tax plus a 20% penalty — but only on the earnings, not on your contributions. After age 65, the penalty goes away, though non-medical withdrawals are still taxed as income.

If you switch back to an HDHP later — say, you change jobs and your new employer offers an HDHP — you can resume contributions when ready. There is no waiting period or re-qualification process.

Frequently Asked Questions

Can I open an HSA if my employer does not offer one?

Yes. If you buy an HDHP on the individual market or through a spouse's plan, you can open an HSA at any bank or investment firm that offers them. You do not need employer sponsorship. You will need proof of HDHP coverage, usually your insurance card or a letter from your insurer.

What if I have an HDHP but my spouse does not?

You can open an HSA because you are covered by an HDHP. Your spouse cannot open one unless they are also enrolled in an HDHP. If you have family coverage under an HDHP, both of you are HSA-may be able to access, but if your spouse is on a separate non-HDHP plan, they are not.

Can I open an HSA if I am on my parents' health insurance?

Not if you are claimed as a dependent on their tax return. The IRS prohibits dependents from owning their own HSAs. Your parent could open an HSA on your behalf if you are covered by their HDHP, but you would not control the account.

Do I have to use my employer's HSA provider?

No. You can open an HSA at any financial institution that offers them, even if your employer sponsors a different one. Keep in mind that if you contribute through your employer's plan, your total contributions across all accounts cannot exceed the annual limit.

What if I turn 65 and enroll in Medicare?

You lose HSA may be able to access the month Medicare begins. You cannot make new contributions, but you keep the money in your account and can withdraw it for medical expenses tax-free. After 65, you can withdraw for any reason without the 20% penalty, though non-medical withdrawals are taxed as income.
