The Basic Requirements for an HSA

You can open a health savings account if you are enrolled in a high-deductible health plan (HDHP) and meet three conditions: you have no other health coverage, you are not claimed as a dependent on someone else's tax return, and you are not enrolled in Medicare. The HDHP itself sets the floor—without one, you cannot open an HSA, regardless of income or employment status.

The IRS updates the deductible thresholds each year. For 2024, an HDHP for individual coverage must have a deductible of at least $1,600 and out-of-pocket maximum of no more than $8,050. For family coverage, the deductible must be at least $3,200 with an out-of-pocket maximum of no more than $16,100. These numbers change annually, so confirm the current year's limits with your plan or the IRS website before opening an account.

You do not need to be employed to open an HSA. Self-employed people, part-time workers, and those with individual market plans can all open one, as long as they are enrolled in an HDHP and meet the other three conditions.

Key Takeaways

  • You must be enrolled in a high-deductible health plan to open an HSA; no HDHP means no account, regardless of other circumstances.
  • You cannot have other health coverage, be claimed as a dependent, or be enrolled in Medicare while holding an HSA.
  • The IRS sets minimum deductibles and maximum out-of-pocket limits for HDHPs each year, and your plan must fall within those ranges.
  • Employment status does not matter—self-employed and part-time workers can open HSAs if they meet the coverage and dependent requirements.
  • You can open an HSA through your employer's plan, through an insurance marketplace, or through a bank or financial institution that offers HSA accounts.

When Other Health Coverage Disqualifies You

Having any other health insurance—beyond your HDHP—blocks you from opening or contributing to an HSA. This includes coverage through a spouse's employer plan, a parent's plan (if you are under 26), Medicaid, or a separate accident or dental plan. The rule is strict: even if the other coverage is minimal, it counts as disqualifying.

The exception is limited-scope coverage that the IRS explicitly allows. Dental-only plans, vision-only plans, workers' compensation, and specific disease insurance (like cancer coverage) do not disqualify you. Likewise, coverage for accidents, disability, or long-term care does not block an HSA. But if you have any general health coverage outside your HDHP, you cannot contribute.

If you lose other coverage during the year—say your spouse's plan ends—you can open an HSA in the month you lose that coverage and contribute for the remainder of the year. You do not have to wait until January.

Dependent Status and Tax Return Rules

If someone else claims you as a dependent on their tax return, you cannot open an HSA, even if you are enrolled in an HDHP. This rule applies regardless of age or whether you pay your own premiums. The IRS treats dependent status as disqualifying because dependents cannot claim their own HSA deductions.

Once you are no longer claimed as a dependent—typically when you file your own return and meet the IRS definition of independence—you become may be able to access. This often happens when you turn 24 or 25, but the exact age varies by your family's income and living situation. If you are unsure whether you will be claimed as a dependent in a given year, ask the person supporting you before opening an account.

Medicare Enrollment and Age Limits

Enrolling in Medicare ends your HSA may be able to access immediately. You cannot contribute to an HSA once you are on Medicare, even if you are still working or have an HDHP. This applies to all parts of Medicare—Part A, Part B, or Part D—and the restriction is permanent for that year and forward.

If you are approaching 65, you can continue contributing to your HSA up until the month you enroll in Medicare. Many people delay Medicare enrollment to keep their HSA contributions open longer, but once enrolled, contributions stop. You can still withdraw money from an existing HSA for may have access to medical expenses at any age, even after Medicare enrollment.

Self-Employed and Gig Worker may be able to access

Self-employed people and gig workers can open HSAs as long as they purchase an HDHP through the individual market (not through an employer) and meet the other requirements. You do not need W-2 income or a traditional job—only an HDHP and the absence of other disqualifying coverage.

If you are self-employed and have employees, you can offer an HDHP through a small business health plan, and both you and your employees can open HSAs. The rules are the same: each person must be enrolled in the HDHP and meet the dependent and Medicare conditions. Self-employed people also deduct HSA contributions on their tax return, similar to traditional employees.

Opening an HSA Through Your Employer or Independently

If your employer offers an HDHP, they often partner with a bank or financial institution to provide HSA accounts. You can open an account through that provider during your employer's open enrollment period. Contributions are usually deducted from your paycheck pre-tax, which lowers your taxable income.

If your employer does not offer an HSA, or if you are self-employed or have an individual market plan, you can open an HSA independently through a bank, credit union, or financial services company. Search for "HSA provider" or "HSA bank" to find institutions in your area. You will need to provide proof of HDHP enrollment (usually a copy of your plan documents or insurance card) when you open the account.

Some employers offer multiple HSA providers to choose from. Compare fees, investment options, and customer service before selecting one. Once you open an account, you can change providers later, though you will need to roll over your existing balance to the new account.

Frequently Asked Questions

Can I open an HSA if I have a spouse on a different health plan?

No. If your spouse has any health coverage outside your HDHP—even if it is their own separate plan—you cannot contribute to an HSA. Both spouses must either be on the same HDHP or have no other coverage. Some couples solve this by both enrolling in the same family HDHP.

What if I turn 26 and age off my parents' plan?

Once you are no longer claimed as a dependent and you enroll in your own HDHP, you become may be able to access to open an HSA. You can open one in the month you lose your parents' coverage and contribute for the rest of that year. Confirm with your parents whether they will claim you as a dependent before opening the account.

Can I open an HSA if I am on Medicaid?

No. Medicaid is considered health coverage, and having it disqualifies you from opening or contributing to an HSA. If you lose Medicaid coverage, you can open an HSA in the month you lose it and contribute for the remainder of the year.

Do I need a job to open an HSA?

No. You need an HDHP, but you can purchase one through the individual market as a self-employed person, freelancer, or gig worker. Employment status does not matter as long as you meet the other requirements: no other coverage, not a dependent, and not on Medicare.

Can I open an HSA if my HDHP deductible is lower than the IRS minimum?

No. Your plan must meet the IRS minimum deductible for the year. If your deductible is below the threshold, you cannot open an HSA with that plan. You would need to switch to a plan that meets the minimum to become may be able to access.
