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 except what the plan allows, 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—if your plan does not meet the IRS definition of a high-deductible plan, you cannot open an HSA, even if you want to.

The IRS updates the deductible thresholds each year. For 2024, a high-deductible plan means a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. Your employer or insurance company will tell you whether your plan qualifies; you do not have to calculate this yourself. If you are unsure, ask your benefits administrator or check your plan documents for the phrase "HSA-may be able to access" or "HSA-may have access to."

Key Takeaways

  • You must be enrolled in a high-deductible health plan (HDHP) with a deductible of at least $1,600 for individual or $3,200 for family coverage in 2024 to open an HSA.
  • You cannot have other health coverage at the same time, with limited exceptions for specific plans like dental-only or vision-only coverage.
  • You cannot be claimed as a dependent on someone else's tax return or enrolled in Medicare, even if you have an HDHP.
  • Your employer may offer an HSA through payroll, or you can open one independently at a bank or financial institution that administers HSAs.
  • The IRS updates deductible thresholds annually, so verify your plan's status each year rather than assuming it remains HSA-may be able to access.

What "Other Health Coverage" Actually Means

The rule against other coverage is stricter than it sounds at first. You cannot have a spouse's health plan, a parent's plan, or coverage through a second job. You also cannot have coverage from the Veterans Administration, TRICARE, or most Medicaid plans. However, some types of coverage do not disqualify you: dental-only plans, vision-only plans, workers' compensation, accident or disability insurance, and long-term care insurance all allow you to keep your HSA.

The tricky part is coverage that overlaps with your HDHP in ways that are hard to see. If your spouse has a family plan that covers you, you are disqualified, even if you do not use it. If you have a health plan through a second employer, you are disqualified. If you are covered under a parent's plan and are under 26, you are disqualified. The rule is about what coverage exists, not whether you actually use it.

Medicare and Age-Related Restrictions

Once you enroll in Medicare—Part A, Part B, or Part D—you can no longer contribute to an HSA, even if you also have an HDHP. This is true even if you enroll in Medicare while still working. Many people assume they can keep both, but the IRS does not allow it. If you have already contributed to your HSA for the year and then enroll in Medicare, you may owe taxes and a penalty on the contributions made after your Medicare enrollment date.

There is no age limit for opening an HSA before Medicare. You can open one at 30, 50, or 62, as long as you have an HDHP and meet the other requirements. The restriction only kicks in when you actually enroll in Medicare, which typically happens at 65 but can happen earlier if you receive Social Security disability benefits.

Dependent Status and Tax Filing

If someone else claims you as a dependent on their tax return, you cannot open an HSA, regardless of whether you have your own HDHP. This affects many people in their early twenties who are still claimed by parents, and also affects adult children claimed by parents for tax purposes. The restriction is based on tax filing status, not on whether the other person actually pays for your health plan.

If you are unsure whether you are claimed as a dependent, ask the person who files your taxes or check your own tax return from the previous year. If you are claimed, you will need to stop being claimed before you can open an HSA. This usually means waiting until the next tax year, when you can file independently.

How to Verify Your Plan's HSA may be able to access

Do not assume your high-deductible plan is HSA-may be able to access just because it has a high deductible. The IRS has specific rules about out-of-pocket maximums, copayments, and other features. Your employer's benefits guide or your insurance company's website should state clearly whether the plan is "HSA-may be able to access" or "HSA-may have access to." If it does not say so explicitly, contact your benefits administrator or insurance company and ask directly.

If you buy your own plan on the health insurance marketplace, the plan listing will show whether it is HSA-may be able to access. Some plans are designed to be HSA-compatible; others are not. The marketplace does not always make this obvious, so read the plan details or call the insurer to confirm before you enroll.

Opening an HSA If Your Employer Does Not Offer One

Many employers offer HSAs through payroll, which makes contributions straightforward and reduces your taxable income automatically. If your employer does not offer one, you can open an HSA independently at a bank, credit union, or financial services company that administers HSAs. You will need to provide proof that you are enrolled in an HSA-may be able to access plan—usually a copy of your plan documents or a letter from your insurance company.

Opening an independent HSA takes a few days to a week. You will fill out an process, provide your plan information, and choose how to fund the account (lump sum, monthly transfers, or both). You will also choose how the money is invested—some HSAs offer savings accounts only, while others offer investment options like mutual funds. Once the account is open, you can contribute up to the annual limit set by the IRS.

What Happens If Your Plan Status Changes

If you lose your HDHP coverage or gain other health coverage during the year, you can no longer contribute to your HSA for the remainder of that year. However, money already in the account stays there and can be used for medical expenses at any time. If you regain HDHP coverage later, you can resume contributions in the month you re-enroll.

If your employer's plan stops being HSA-may be able to access—for example, because the deductible was lowered—you will be notified by your benefits administrator. You will not be able to contribute further, but again, existing funds remain yours to use. Keep track of these changes each year, especially if you switch jobs or your employer changes plans.
