You need a high-deductible health plan to open an HSA

The single requirement to open a Health Savings Account is that you are enrolled in a high-deductible health plan (HDHP). Your health insurance provider will tell you whether your plan qualifies. If your plan meets the IRS definition of an HDHP—which means it has a minimum deductible and maximum out-of-pocket costs set by the IRS each year—you become HSA-may be able to access the moment your coverage starts.

You do not need to be self-employed, work for a large employer, or have any particular income level. You do not need to have used up your deductible or spent money on medical care. The only thing that matters is the type of plan you hold.

If you are unsure whether your plan is an HDHP, check your insurance documents or call your plan's customer service line. They can confirm your plan's deductible and out-of-pocket maximum, which you can then compare to the IRS limits for the current year.

Key Takeaways

  • You must be enrolled in a high-deductible health plan (HDHP) to open an HSA; this is the only requirement.
  • Your employer does not have to offer an HSA or contribute to one for you to open and fund your own account.
  • You cannot have other health coverage at the same time, such as a spouse's traditional PPO or HMO plan, unless that plan also qualifies as an HDHP.
  • You must be a U.S. citizen or resident alien with a valid Social Security number to open an HSA.
  • You cannot be claimed as a dependent on someone else's tax return and also open your own HSA.

Who is disqualified from opening an HSA

Even if you have an HDHP, you cannot open an HSA if you have other health coverage running at the same time. This includes Medicare, Medicaid, TRICARE (military health coverage), the Veterans Health Administration, or a spouse's traditional health plan. The rule exists because HSAs are designed to pair with high-deductible plans, not to sit alongside comprehensive coverage.

If your spouse has an HDHP and you have a traditional plan, only your spouse can open an HSA. If both of you have HDHPs, you can each open your own account. If one of you switches to a traditional plan later, that person must stop contributing to their HSA, though they can keep the account and the money already in it.

You also cannot open an HSA if you are claimed as a dependent on someone else's tax return, even if you have your own HDHP. This rule applies most often to adult children living with parents. Once you file your own return and are no longer a dependent, you become HSA-may be able to access.

Age and citizenship requirements

You must be a U.S. citizen or resident alien to open an HSA. You will need a valid Social Security number. There is no age limit—you can open an HSA at any age as long as you have an HDHP and meet the other requirements.

Once you turn 65, you become may be able to access for Medicare. At that point, you can no longer make new contributions to an HSA. However, you can keep the account open and withdraw money from it for any reason without penalty, though non-medical withdrawals will be taxed as ordinary income.

Self-employed and gig workers

If you are self-employed or work as an independent contractor, you can open an HSA as long as you purchase an HDHP on your own. You do not need to work for an employer that offers one. Many self-employed people buy HDHPs through the Health Insurance Marketplace or directly from insurers.

You can contribute to your HSA even if your business has no employees or minimal income in a given year. The contribution limits are the same as for anyone else with an HDHP. If you are self-employed, you may also be able to deduct HSA contributions as a business expense on your tax return, though the rules vary depending on your business structure.

Employer-sponsored plans and employee choice

If your employer offers an HDHP, you can enroll in it during open enrollment or when you first become may be able to access. Your employer may also offer to contribute money to your HSA—this is called an employer contribution or employer match. However, your employer's contribution is optional; they are not required to fund your account.

If your employer offers both an HDHP and a traditional plan, you choose which one to enroll in. Only the HDHP makes you HSA-may be able to access. If you choose the traditional plan, you cannot open an HSA that year, even if you have an HDHP from another source (such as a spouse's plan).

If you leave your job, you keep your HSA. The account belongs to you, not your employer. You can continue to use the money in it for medical expenses, and you can keep contributing to it if you maintain an HDHP through another source, such as the Marketplace or a spouse's plan.

Married couples and family coverage

If you and your spouse both have individual HDHPs, you can each open your own HSA and contribute separately. If you have family coverage under one HDHP, only one of you can open an HSA—typically the person whose name is on the policy. The other spouse cannot open a second account for the same family plan.

If you have family coverage and want both spouses to have HSAs, you would need to switch to two individual HDHP plans, one for each person. This is sometimes more expensive than family coverage, so compare the costs before making the change.

Money in one spouse's HSA can be used to pay for the other spouse's medical expenses, and after one spouse dies, the surviving spouse can inherit the HSA. However, each account is separate for contribution and withdrawal purposes while both spouses are living.

Students and part-time workers

Students can open an HSA if they are enrolled in an HDHP and meet all other requirements. If a student is claimed as a dependent on a parent's tax return, they cannot open an HSA, even if they have their own HDHP. Once they file their own return and are no longer a dependent, they become HSA-may be able to access.

Part-time workers can open an HSA if their employer's plan is an HDHP. If you work part-time and also have coverage through another source—such as a spouse's plan or a parent's plan—you can only open an HSA if all your coverage is HDHP-based. Having both an HDHP and any other type of health plan disqualifies you.
