Not everyone can open an HSA, and the rules are strict about who qualifies

You can open an HSA only if you are enrolled in a high-deductible health plan (HDHP) and meet three other conditions at the same time. If you have other health coverage—Medicare, Medicaid, a spouse's plan, or even a parent's plan if you are under 26—you cannot open an HSA, even if your main coverage is an HDHP. The IRS enforces these rules, and violations can trigger taxes and penalties on money you withdraw.

The timing matters too. You can open an HSA only during the months you are actually covered by an HDHP. If you switch to a regular health plan in July, you cannot keep contributing to the HSA for the rest of that year, though you can still spend money already in it.

Key Takeaways

  • You must be enrolled in an HDHP with no other health coverage (except specific exceptions like dental or vision plans) to open an HSA.
  • Medicare enrollment, Medicaid coverage, or being claimed as a dependent on someone else's health plan all disqualify you from HSA contributions.
  • You can open an HSA yourself through a bank or financial institution, not through your employer—though employers often offer HSA accounts as a payroll option.
  • The IRS sets minimum deductibles and maximum out-of-pocket costs each year; your HDHP must fall within those ranges to may have access to.
  • If you lose HSA may be able to access mid-year, you stop contributing when ready but keep the money already in the account and can still spend it.

The three conditions you must meet at the same time

First, you must be enrolled in an HDHP. For 2024, that means a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. Your plan's maximum out-of-pocket costs cannot exceed $4,050 for individual or $8,050 for family. These numbers change each year, so check the current year's limits before opening an account.

Second, you cannot have any other health coverage except specific carve-outs. Dental and vision plans do not disqualify you. Neither do accident, disability, long-term care, or workers' compensation plans. But a spouse's health plan, a parent's plan (if you are under 26), Medicare, Medicaid, TRICARE, or the Veterans Administration all block you from contributing to an HSA.

Third, you cannot be claimed as a dependent on someone else's tax return if that person has health coverage. This rule catches many people in their mid-20s who are still on a parent's plan and still claimed as dependents.

Who the IRS specifically excludes

Medicare beneficiaries cannot open an HSA or contribute to one they already have. Once you enroll in Medicare Part A or Part B, your HSA may be able to access ends when ready. If you are already contributing and you turn 65, you can still withdraw money from the account, but you cannot add more.

Medicaid recipients face a similar block. If you are enrolled in Medicaid at any point during a month, you cannot contribute to an HSA for that month, even if you also have an HDHP. Some states have programs that let you keep an HDHP while receiving Medicaid, but the IRS rule still applies—you cannot contribute during months you hold Medicaid coverage.

People covered under a spouse's health plan cannot open an HSA, regardless of whether that plan is an HDHP. The rule applies even if the spouse's plan is terrible and you would rather use your own HDHP. If both spouses have separate HDHP coverage with no overlap, each can open their own HSA.

How to open an HSA if you meet the conditions

You do not need your employer to open an HSA. You can open one yourself at any bank, credit union, or financial institution that offers HSA accounts. Many employers offer HSA accounts through payroll, which is convenient because contributions come out pre-tax. But if your employer does not offer one, or if you want to move your HSA to a different institution, you can open an account independently.

When you open an account, the institution will ask for proof that you are enrolled in an HDHP. This is usually your insurance card or a letter from your health plan showing the deductible and out-of-pocket maximum. Some institutions ask you to self-certify that you meet the other conditions (no other coverage, not on Medicare, not a dependent). The IRS can audit this later, so be honest.

Once the account is open, you can contribute up to the annual limit set by the IRS. For 2024, that is $4,150 for individual coverage or $8,300 for family coverage. If you are 55 or older, you can add an extra $1,000 per year. Your employer may contribute, you may contribute, or both—the limit is the total across all sources.

What happens if you lose may be able to access mid-year

If you switch to a non-HDHP plan, enroll in Medicare, or gain other health coverage, you stop being able to contribute to your HSA when ready. You cannot make contributions for the rest of that calendar year. However, you keep the money already in the account and can spend it on may have access to medical expenses for the rest of your life.

If you contributed too much before losing may be able to access, you may owe taxes and a 20 percent penalty on the excess. For example, if you contributed $2,000 in January and lost may be able to access in March, you can only keep the amount you contributed for the months you were may be able to access (January through March). You would need to withdraw the excess and report it on your tax return.

Self-employed people and HSA accounts

Self-employed people can open an HSA if they enroll in an HDHP and meet all other conditions. They can contribute through the HSA account itself or claim the contribution as a deduction on their tax return. The contribution limit is the same as for employees.

If you are self-employed and also have employees, you cannot discriminate in HSA contributions. If you contribute to your own HSA, you must offer the same opportunity to employees on the same HDHP. You do not have to match their contributions, but you cannot exclude them from opening accounts.

Common reasons people think they can open an HSA but cannot

Being on a spouse's plan is the most common disqualifier. Even if you have your own HDHP through your job, you cannot contribute to an HSA if your spouse has any other health coverage and you are covered under it. The rule is about coverage, not about who pays the premium.

Being claimed as a dependent also blocks many people. If your parents claim you on their taxes and they have health coverage, you cannot open an HSA even if you are enrolled in your own HDHP through your job. This changes once you are no longer claimed as a dependent, usually after age 26 or when you become financially independent.

Having a regular health plan with a high deductible is not the same as having an HDHP. Some plans have high deductibles but do not meet the IRS definition of an HDHP because their out-of-pocket maximum is too high or they cover preventive care differently. Check your plan documents or call your insurer to confirm it qualifies.

Frequently Asked Questions

Can I open an HSA if I am on my parent's health plan?

No. If you are covered under your parent's health plan, you cannot contribute to an HSA, even if you also have your own HDHP through your job. You can open an account once you are no longer covered under their plan and are no longer claimed as a dependent on their tax return.

What if my spouse has an HDHP but I have a regular plan?

You cannot open an HSA because you have other health coverage. Your spouse can open an HSA for their individual coverage. If you both want HSA accounts, you would both need to be on separate HDHP plans with no overlap in coverage.

Can I open an HSA if I am turning 65 soon?

You can open one now if you meet all conditions, but you will lose may be able to access the month you enroll in Medicare. You can continue to spend money already in the account after that, but you cannot add more contributions once Medicare begins.
