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

You can open an HSA 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 or Medicaid, you cannot open an HSA, no matter how much money you want to set aside. The account itself is not the barrier — the insurance plan you carry is.

An HDHP is a specific category of health insurance with a higher deductible than traditional plans. In 2024, an HDHP for individual coverage must have a deductible of at least $1,600, and for family coverage at least $3,200. These numbers change each year. If your plan meets that threshold and is labeled as HSA-compatible by your insurer, you are may be able to access to open an account. If it is not labeled that way, do not assume — call your insurer and ask directly whether your plan qualifies.

Self-employed people and people who buy their own insurance can open an HSA if they choose an HDHP on the individual market. You do not need an employer to sponsor the plan. You also do not need to be young or healthy — age and medical history do not factor into HSA may be able to access. What matters is the plan type alone.

Key Takeaways

  • You must be enrolled in an HDHP to open an HSA; standard health plans, Medicare, and Medicaid disqualify you.
  • Your insurer must label the plan as HSA-compatible; not all high-deductible plans may have access to, so verify with the insurance company.
  • Self-employed people and individual insurance buyers can open an HSA if they choose an HDHP on the open market.
  • You cannot have an HSA and a Flexible Spending Account (FSA) at the same time, though you can switch between them in different years.
  • Once you open an HSA, you keep it even if you change jobs or switch to a different health plan — the account belongs to you.

Who is blocked from opening an HSA

Medicare enrollees cannot open an HSA, even if they are still working and have employer coverage. Once you turn 65 and enroll in Medicare Part A, you lose HSA may be able to access immediately. If you already have an HSA, you can keep the money in it and spend it on may have access to medical expenses, but you cannot make new contributions.

Medicaid recipients are also ineligible. Some states run Medicaid programs that include an HDHP option, but those plans do not may have access to for HSA status under federal rules. If you are on Medicaid, you cannot open an HSA.

People covered by a spouse's FSA or by a general-purpose FSA cannot open an HSA in the same year. The IRS treats these accounts as incompatible — you can use one or the other, but not both. If you have an FSA through your employer and want to switch to an HSA, you must wait until the next plan year and drop the FSA first. Some employers allow you to make this switch during open enrollment; others do not.

Dependents claimed on someone else's tax return can still open an HSA if they have their own HDHP, but the rules around who can claim the account as a dependent get complicated. If you are in this situation, check with a tax professional or your HSA provider before opening the account.

What happens if your employer switches your plan

If your employer moves you from an HDHP to a standard plan, you stop being able to contribute to your HSA that year. You keep the account and the money already in it, but new contributions are blocked. You can still spend the balance on may have access to medical expenses without penalty.

If your employer switches you to a different HDHP, you remain may be able to access and can keep contributing. The account itself does not change — you just update your payroll deduction if your employer offers one.

If you leave your job, your HSA goes with you. You own it outright. You can continue to contribute if you buy an HDHP on the individual market, or you can stop contributing and just spend down the balance. The account does not close and the money does not disappear because you changed employers.

Self-employed and gig workers

If you are self-employed or a gig worker, you can open an HSA as long as you buy an HDHP for yourself on the individual market (through your state's health insurance marketplace or directly from an insurer). You do not need an employer to sponsor the plan. You also do not need to have employees or a formal business structure — sole proprietors may have access to.

Self-employed people can deduct HSA contributions on their tax return, just like they deduct health insurance premiums. This is one of the few tax deductions available to self-employed people for health costs. Keep records of your contributions and your HDHP enrollment to document this deduction.

How to verify your plan qualifies

Do not assume your high-deductible plan is HSA-compatible. Some insurers offer high-deductible plans that do not meet the IRS definition of an HDHP. The difference is usually in the out-of-pocket maximum or the coverage rules for preventive care.

Call your health insurance company directly and ask: "Is my plan HSA-may be able to access?" or "Is my plan an IRS-may have access to HDHP?" They will tell you yes or no. If yes, ask them to confirm the plan name and policy number. If no, ask what would need to change for you to switch to an HSA-may be able to access plan.

If you are shopping for insurance and want an HSA, search the marketplace or insurer websites for plans labeled "HDHP" or "HSA-may be able to access." These are usually listed as a separate category from standard plans. The plan documents will state whether it qualifies for HSA contributions.

Opening an account once you confirm may be able to access

Once you know your plan qualifies, you can open an HSA through a bank, credit union, or financial institution that offers them. You do not have to use the provider your employer recommends, though many employers offer payroll deduction through a specific provider. Payroll deduction is convenient because the money comes out before taxes, but it is not required.

You will need your Social Security number, proof of HDHP enrollment (usually your insurance card or a letter from your insurer), and a valid ID. The process typically takes a few minutes online or over the phone. Some providers charge a monthly maintenance fee; others do not. Compare providers before you choose one.

Once the account is open, you can start contributing immediately. If you are contributing through payroll, the deduction usually starts in the next pay period. If you are contributing on your own, you can deposit money whenever you want, up to the annual limit set by the IRS.
