You cannot open an HSA without may have access to health insurance

The IRS requires that you be enrolled in a high-deductible health plan (HDHP) to open or contribute to a Health Savings Account. You cannot have an HSA sitting alone without insurance behind it. If you lose your HDHP coverage, you can keep the HSA and the money in it, but you cannot add new contributions until you re-enroll in an HDHP.

This is a hard rule, not a workaround situation. The HSA exists specifically as a tax-advantaged savings tool paired with high-deductible insurance. Without that insurance, the account has no legal basis to exist.

Key Takeaways

  • An HSA requires active enrollment in an HDHP; you cannot open one with any other insurance type or without insurance at all.
  • Once you open an HSA, you keep the account and its money even if you switch to different insurance, but you cannot contribute new funds until you return to an HDHP.
  • If you are uninsured or on a non-HDHP plan, you can save for medical costs in a regular savings account instead, though without the tax advantages.
  • Some employers offer HDHPs as their only plan option, while others offer them alongside traditional plans — check what your employer provides.

What qualifies as an HDHP for HSA purposes

An HDHP is not just any plan with a high deductible. The IRS sets specific minimum deductible amounts and maximum out-of-pocket limits each year. For 2024, an individual HDHP must have a deductible of at least $1,600 and a maximum out-of-pocket limit of $3,200. Family plans must have a deductible of at least $3,200 and a maximum out-of-pocket limit of $6,400. These numbers change annually.

Your plan must also meet other requirements: it cannot cover preventive care before you meet the deductible (though preventive care itself is usually free), and it cannot have features that disqualify it, such as a Health Reimbursement Arrangement (HRA) that pays claims before the deductible is met. If you are unsure whether your current plan qualifies, your insurance company or employer's benefits office can confirm this in writing.

Where to find an HDHP if you don't have one

If your employer offers health insurance, check whether an HDHP is one of the options. Many employers now offer at least one HDHP alongside traditional plans. If your employer does not offer an HDHP, or if you are self-employed or uninsured, you can purchase one directly from an insurance company or through the Health Insurance Marketplace (Healthcare.gov or your state's equivalent).

Plans sold on the Marketplace are labeled by metal tier (Bronze, Silver, Gold, Platinum) and some Bronze and Silver plans are structured as HDHPs. When you search the Marketplace, you can filter by deductible amount to find plans that meet the HDHP threshold. Costs vary by state, age, and income, and you may be may be able to access for subsidies that lower your monthly premium.

What happens to your HSA if you lose HDHP coverage

If you leave your HDHP — whether by switching to a traditional plan, losing coverage, or changing jobs — you keep the HSA and all the money in it. The account does not close. However, you cannot make new contributions while you are not enrolled in an HDHP. You can continue to withdraw money from the account for may have access to medical expenses without penalty, and the money continues to grow tax-free if you invest it.

If you later re-enroll in an HDHP, you can resume contributions when ready. There is no waiting period or re-process process for the HSA itself — you straightforward need the HDHP enrollment to restart contributions. This makes an HSA a long-term tool even if your insurance situation changes.

Alternatives if you cannot get an HDHP

If you are on a traditional health plan, Medicare, Medicaid, or uninsured, you cannot use an HSA. In these situations, a regular savings account is the most straightforward option for setting aside money for medical costs. You do not get the tax deduction or tax-free growth that an HSA provides, but you have full control and no restrictions on how you use the money.

Some employers also offer a Flexible Spending Account (FSA), which is a different tax-advantaged account available with any health plan type. FSAs have lower contribution limits than HSAs and operate on a "use it or lose it" basis — unspent money at the end of the year is forfeited (though there is usually a grace period). If your employer offers an FSA and you are not may be able to access for an HSA, an FSA may be worth considering.

How to open an HSA once you have HDHP coverage

Once you are enrolled in an HDHP, you have several options for opening an HSA. Many employers that offer HDHPs also offer an HSA through a payroll administrator — you straightforward enroll during open enrollment or when you first become may be able to access. If your employer does not offer one, you can open an HSA directly with a bank, credit union, or investment company. Common providers include Fidelity, Lively, HealthEquity, and many regional banks.

You will need to provide proof of HDHP enrollment, usually a copy of your insurance card or a letter from your employer confirming your plan type. The account setup typically takes a few days to a week. Once open, you can contribute up to the annual IRS limit (for 2024, $4,150 for individual coverage or $8,300 for family coverage) either through payroll deductions or direct deposits.
