You can open an HSA on your own, but only if you have the right insurance plan

A Health Savings Account (HSA) does not require an employer. You can open one independently as long as you are enrolled in a High Deductible Health Plan (HDHP) — either through the individual market, a spouse's plan, or Medicare. The plan itself is what matters, not where you get it. If you buy your own HDHP through the healthcare marketplace or a private insurer, you can open an HSA at a bank, credit union, or investment firm without involving an employer at all.

The catch is that not every health plan qualifies. Your plan must meet specific deductible and out-of-pocket limits set by the IRS each year. For 2024, a self-only HDHP must have a deductible of at least $1,600 and out-of-pocket maximum of no more than $8,050. Family plans have higher thresholds. If your plan does not meet these numbers, you cannot open an HSA, even if you want to.

Key Takeaways

  • You need a High Deductible Health Plan to open an HSA — employer coverage is not required, but the right insurance plan is.
  • Individual market plans, spouse's employer plans, and some Medicare plans all may have access to as long as they meet IRS deductible and out-of-pocket limits.
  • You can open an HSA at any bank, credit union, or brokerage that offers them — there is no single provider or government portal.
  • You will need your plan documents or a letter from your insurer confirming HDHP status before you open the account.

Where to buy an HDHP if you do not have employer coverage

The healthcare marketplace (Healthcare.gov or your state's exchange) is the main place to find individual HDHPs. During open enrollment — usually November through January — you can filter plans by deductible amount and see which ones may have access to as HDHPs. The marketplace shows you the monthly premium and the deductible side by side, so you can compare cost.

Outside open enrollment, you can only buy a marketplace plan if you have a may have access to life event: losing job-based coverage, moving to a new state, getting married, having a child, or losing Medicaid. If none of those explore to you, you will have to wait for the next open enrollment period.

Private insurers also sell HDHPs directly. You can contact them outside of open enrollment, though availability and pricing vary by state and age. Some people find better rates this way, especially if they are young and healthy, but you lose the subsidy you might get through the marketplace.

How to confirm your plan qualifies before opening an account

Do not assume your plan is an HDHP just because it has a high deductible. Some plans are called "high deductible" in marketing but do not meet the IRS definition. You need written confirmation from your insurer.

Call your insurance company and ask them directly: "Is my plan an HSA-may have access to High Deductible Health Plan?" Ask them to send you a letter or email stating the plan name, deductible amount, and out-of-pocket maximum. Keep this document — you will need it when you open the account. Many insurers also post this information in your online account portal under plan details or coverage information.

If your insurer says no, your plan does not may have access to, and opening an HSA would violate IRS rules. You would face penalties and have to close the account.

The steps to open an HSA on your own

Once you have confirmed your HDHP status, you can open an account at any financial institution that offers HSAs. Banks, credit unions, and brokerages all compete for this business, and there is no single "official" place to open one.

Start by deciding what you want from the account. If you plan to use it mainly for near-term medical expenses, a bank HSA with a debit card and low or no fees is usually the right choice. If you want to invest the money for long-term growth, look for an HSA provider that offers investment options — typically a brokerage or a bank with investment services.

Then contact the provider and ask what documents they need. Most will ask for: your name, Social Security number, proof of HDHP coverage (the letter from your insurer or a copy of your plan documents), and your plan's deductible and out-of-pocket limits. Some providers have online applications; others require you to mail or fax documents. The process usually takes a few days to a week.

What happens if you lose your HDHP coverage

If you switch to a non-may have access to plan — a standard PPO, HMO, or any plan that does not meet the HDHP definition — you can no longer contribute to your HSA. You can keep the account and the money in it, but you cannot add new funds. If you contribute after losing HDHP status, you will owe taxes and a 20% penalty on the excess amount.

If you regain HDHP coverage later, you can resume contributions. There is no limit to how many times you can stop and restart, as long as you do not contribute while ineligible.

HSA fees and what to watch for

HSA providers charge different fees, and they matter over time. Some charge monthly maintenance fees ($2 to $5), per-transaction fees, or investment management fees. Others charge nothing as long as you keep a minimum balance. A few charge no fees at all.

Compare providers before you open. If you plan to keep less than $1,000 in the account, a provider with no monthly fee is worth more than one with investment options you will not use. If you plan to invest, check whether the investment fees are reasonable — some HSA providers charge higher expense ratios than you would pay at a regular brokerage.

Read the fine print on debit card fees too. Some providers charge for out-of-network ATM withdrawals or charge a fee if you use the card at a non-medical merchant and have to dispute it later.

Frequently Asked Questions

Can I open an HSA if I am on Medicare?

Only if you are under 65 and enrolled in an HDHP before you turn 65. Once you are on Medicare, you cannot open a new HSA or make new contributions. If you already had an HSA before Medicare, you can keep it and withdraw money tax-free for medical expenses, but you cannot add new funds.

What if my spouse has employer coverage and I do not?

If your spouse's plan is an HDHP and covers both of you, you can open a family HSA. If your spouse's plan is not an HDHP but you have your own HDHP, you can open an individual HSA. You cannot have both a family HSA and an individual HSA in the same year — the IRS treats them as one account for contribution limits.

Do I have to use the HSA provider my insurance company recommends?

No. Your insurer may suggest a provider, but you can open an account anywhere. Shop around for fees and features. Your insurance company does not get a cut, and they do not care which provider you choose.

What if I open an HSA and then find out my plan does not may have access to?

Contact your HSA provider and the IRS when ready. You will need to withdraw the money you contributed (called a "correction") and report it on your tax return. You may owe taxes and penalties depending on how long the money sat in the account and whether you spent any of it.

Can I open an HSA if I am self-employed?

Yes, as long as you have an HDHP. Self-employed people often buy plans through the healthcare marketplace or directly from insurers. Once you have the HDHP, opening an HSA works the same way as it does for anyone else.
