You need three things: a high-deductible health plan, U.S. citizenship or residency, and no other health coverage that blocks HSA may be able to access
Not everyone can open a Health Savings Account. The IRS sets specific rules, and the most important one is that you must be enrolled in a high-deductible health plan (HDHP) — a plan with a deductible of at least $1,600 for individual coverage or $3,200 for family coverage in 2024. These thresholds change yearly. If your plan has a lower deductible, you cannot open an HSA, even if you want to.
Beyond the HDHP requirement, you must be a U.S. citizen or resident alien with a valid Social Security number or Individual Taxpayer Identification Number (ITIN). You also cannot be claimed as a dependent on someone else's tax return, and you cannot be enrolled in Medicare. If you turn 65 and start Medicare, your HSA may be able to access ends that month, though you can still withdraw money from an existing account.
The third barrier is other health coverage. If you have any health insurance besides your HDHP — including coverage through a spouse's plan, a parent's plan, or government programs like Medicaid or TRICARE — you are blocked from opening an HSA. The only exceptions are specific plans that do not count: dental-only, vision-only, workers' compensation, disability insurance, and long-term care insurance do not disqualify you.
Key Takeaways
- Your health plan must be a high-deductible plan with a deductible of at least $1,600 (individual) or $3,200 (family) in 2024 to open an HSA.
- You cannot have any other health insurance at the same time, with narrow exceptions for dental, vision, and workers' compensation coverage.
- You must be a U.S. citizen or resident alien, not claimed as a dependent, and not enrolled in Medicare.
- If you have an HSA and then enroll in Medicare or gain other health coverage, you must stop making contributions immediately to avoid tax penalties.
Who is blocked from opening an HSA
Medicare enrollment is an automatic disqualifier. The month you turn 65 and enroll in Medicare Part A or Part B, your HSA may be able to access stops. You can keep the money already in your account and withdraw it tax-free for may have access to medical expenses, but you cannot add another dollar. If you delay Medicare enrollment past 65, you can keep contributing to your HSA during that delay — but the moment you enroll, contributions must stop.
Medicaid coverage also blocks HSA may be able to access. If you are enrolled in any Medicaid plan, you cannot open an HSA or contribute to one you already have. This applies even if Medicaid is your secondary coverage. Some states have programs that let you keep Medicaid while working, and those still disqualify you from HSAs.
Dependents cannot open HSAs. If someone else claims you as a dependent on their tax return — whether you are a child, a young adult, or an adult relative — you are ineligible. This rule applies even if you have your own income and your own HDHP.
Spouses with non-HDHP coverage create a household problem. If you are married and your spouse has a traditional health plan (PPO, HMO, or other non-HDHP), your spouse cannot open an HSA. You can open one if you are on a separate HDHP, but only if your spouse's plan does not cover you. If you are both on the same family plan and it is not a high-deductible plan, neither of you can open an HSA.
How to check if your specific plan qualifies
Your employer or insurance company can tell you whether your plan is HDHP-may have access to. Ask your benefits administrator or HR department directly — do not assume based on the plan name. Some plans are marketed as "high-deductible" but do not meet IRS thresholds. Others meet the deductible requirement but have out-of-pocket maximums that are too low, which also disqualifies them.
If you buy insurance on the individual market, check the plan documents or call the insurer's customer service line. They can confirm whether the plan is HSA-may be able to access. The marketplace website (Healthcare.gov or your state's equivalent) sometimes labels plans as HSA-compatible, but verify with the insurer before opening an account.
The IRS publishes a list of HDHP-may have access to plans, but it is not a complete directory — it is mainly for reference. Your insurance company's confirmation is what matters for your specific enrollment.
What happens if you lose HSA may be able to access mid-year
If you gain other health coverage during the year — through a spouse's job, a new employer, or enrollment in Medicaid — you must stop contributing to your HSA immediately. Contributions made after you become ineligible are subject to a 20% penalty tax plus income tax on the amount contributed. The IRS does not give you a grace period.
The money already in your account stays yours. You can withdraw it tax-free for may have access to medical expenses at any time, even after you are no longer may be able to access to contribute. You just cannot add new money.
If you contributed too much before realizing you were ineligible, you can request a correction from your HSA provider. They can remove the excess contribution and any earnings on it before your tax filing deadline, which avoids the penalty. This is called an excess contribution correction, and it requires paperwork, so contact your HSA provider as soon as you realize the problem.
Self-employed people and HSA may be able to access
Self-employed people can open an HSA if they buy their own HDHP on the individual market or through a professional association plan. The same rules apply: the plan must meet the deductible threshold, and you cannot have other health coverage. You also cannot be enrolled in Medicare.
If you are self-employed and have employees, your business can offer an HDHP to employees, and those employees can open HSAs if they meet all other requirements. You, as the owner, can also open an HSA if you are enrolled in the same HDHP or a separate HDHP.
Contribution limits and who can contribute on your behalf
Once you are may be able to access, you can contribute up to $4,150 for individual coverage or $8,300 for family coverage in 2024 (these limits increase yearly). Your employer can contribute to your HSA, your spouse can contribute, or you can contribute yourself. Contributions from any source count toward the same annual limit — they do not stack.
If you are over 55, you can contribute an extra $1,000 per year as a catch-up contribution. This applies only to you as an individual, not to your spouse, even if your spouse is also over 55 and has an HSA.
Contributions must be made by your tax filing deadline (usually April 15 of the following year) to count toward that tax year. Employer contributions are typically made during the plan year, but you can make personal contributions up until the deadline.
Frequently Asked Questions
Can I open an HSA if my spouse has a regular health plan?
Only if you are not covered by your spouse's plan. If you are enrolled in your own separate HDHP and your spouse has a non-HDHP plan, you can open an HSA. But if you are both on the same family plan and it is not a high-deductible plan, neither of you can open an HSA.
What if I turn 65 and enroll in Medicare?
Your HSA may be able to access ends the month you enroll in Medicare Part A or Part B. You cannot make new contributions after that month, but you keep the money in your account and can withdraw it tax-free for may have access to medical expenses for the rest of your life.
Can I open an HSA if I have Medicaid?
No. Medicaid enrollment disqualifies you from opening an HSA or contributing to one you already have. This applies even if Medicaid is secondary coverage or if you are in a work-incentive program that lets you keep Medicaid while employed.
What if I contribute to an HSA and then find out I was ineligible?
Contact your HSA provider immediately and ask about an excess contribution correction. They can remove the ineligible contribution and related earnings before your tax deadline, which avoids the 20% penalty. If you do not correct it, you will owe the penalty plus income tax on the amount.
Do I need to open an HSA through my employer?
No. If your employer offers an HSA, you can use it, but you can also open an HSA with a bank, credit union, or investment company on your own. You are not required to use your employer's plan. Some people open their own HSA to get better investment options or lower fees.
