The Basic Requirements for an HSA

To open a Health Savings Account, you must be enrolled in a High Deductible Health Plan (HDHP) — a specific type of health insurance with a deductible of at least $1,600 for individual coverage or $3,200 for family coverage in 2024. You cannot have other health coverage at the same time, with narrow exceptions for specific plans like dental, vision, or workers' compensation. You also cannot be claimed as a dependent on someone else's tax return, and you cannot be enrolled in Medicare.

The HDHP requirement is the hard boundary. If your employer offers a traditional PPO or HMO plan, or if you have coverage through a spouse's plan that is not an HDHP, you cannot open an HSA. If you are on Medicare, you lose HSA may be able to access the month you enroll, even if you keep an HDHP as secondary coverage.

You must be a U.S. citizen or resident alien with a valid Social Security number. Non-citizens on certain visa types may not open an HSA, though the rules vary by visa category.

Key Takeaways

  • You must be enrolled in an HDHP with a deductible of at least $1,600 (individual) or $3,200 (family) as of 2024, and have no other health coverage except specific carve-outs like dental or vision.
  • You cannot be on Medicare, claimed as a dependent, or covered by a spouse's non-HDHP plan at any point during the month you want to contribute to an HSA.
  • Your employer does not have to offer an HSA for you to open one — you can open an individual HSA if you buy an HDHP on the private market or through the ACA marketplace.
  • If you lose HDHP coverage mid-year, you can still make contributions for the months you were covered, but you cannot make contributions for months after coverage ends.
  • Married couples can each open separate HSAs if both are enrolled in individual HDHPs, or one joint HSA if both are on a family HDHP.

HDHP Coverage and Where to Find It

An HDHP is a real insurance plan, not a savings account. Your employer may offer one as an option during open enrollment — if they do, you will see it listed alongside other plan choices. If your employer does not offer an HDHP, you can purchase one directly from an insurance company or through the ACA marketplace (Healthcare.gov or your state's equivalent). Plans sold on the marketplace are clearly labeled by metal tier (Bronze, Silver, Gold, Platinum) and deductible amount.

Not every plan sold as "high deductible" meets the IRS definition required for HSA may be able to access. The plan must have an out-of-pocket maximum (the most you pay in a year for covered services) of no more than $4,150 for individual coverage or $8,300 for family coverage in 2024. If a plan has a lower deductible but a very high out-of-pocket maximum, it may not may have access to. When shopping, look for plans explicitly labeled as HSA-may be able to access or HSA-compatible.

If you are self-employed or a business owner, you can purchase an HDHP on the individual market and open an HSA. You do not need employees or a group plan.

Coverage Conflicts That Disqualify You

You cannot have any other health coverage in the same month you contribute to an HSA, with specific exceptions. Dental and vision plans do not disqualify you, nor do accident, disability, long-term care, or workers' compensation coverage. Retiree health plans, TRICARE (military coverage), or the Veterans Administration also do not block HSA may be able to access.

Spousal coverage is the most common conflict. If your spouse has a non-HDHP plan and you are covered under it, you cannot open an HSA — even if you also have your own HDHP. The rule applies to the entire month: if you are covered by a disqualifying plan on even one day of the month, you cannot contribute to an HSA for that month. If your spouse's coverage ends mid-month, you can contribute starting the following month.

If you are covered by both an HDHP and a non-HDHP plan (for example, your employer offers both and you enroll in both by mistake), you lose HSA may be able to access for as long as both are active. You must drop the non-HDHP plan to restore may be able to access.

Age, Medicare, and Dependent Status

There is no age limit to open an HSA — you can open one at 25 or at 55. However, Medicare enrollment ends HSA may be able to access immediately. The month you turn 65 and enroll in Medicare Part A or Part B, you can no longer contribute to an HSA. If you delay Medicare enrollment past 65, you can continue contributing to an HSA as long as you are not actually enrolled. Once you enroll, contributions stop.

If you are claimed as a dependent on someone else's tax return — typically a parent claiming an adult child — you cannot open an HSA, even if you have your own HDHP. This rule applies regardless of whether the dependent actually receives financial support. The tax filing status is what matters. If you stop being claimed as a dependent, you can open an HSA starting the following year.

Married couples filing jointly can each have their own HSA if both are on individual HDHPs, or one joint HSA if both are on a family HDHP. If one spouse is on Medicare and the other is on an HDHP, only the non-Medicare spouse can contribute.

Contribution Limits and Timing

Your HSA contribution limit depends on your coverage type and the calendar year. For 2024, the limit is $4,150 for individual coverage or $8,550 for family coverage. If you are 55 or older, you can contribute an additional $1,000 per year (called a catch-up contribution). These limits change annually and are set by the IRS.

You can only contribute to an HSA for months in which you meet all the requirements. If you enroll in an HDHP on March 1, you can contribute for March through December of that year — nine months. If you lose HDHP coverage on August 15, you can contribute for January through August, but not September through December. Your HSA provider will track your contribution room and may reject contributions that exceed your may be able to access months.

If your employer contributes to your HSA, that amount counts toward your annual limit. If your employer contributes $2,000 and you want to contribute $2,150, your total is $4,150 — you can only add $2,150 yourself.

Self-Employed and Business Owner Rules

If you are self-employed or own a business with no employees, you can open an HSA by purchasing an HDHP on the individual market. You are not required to offer an HSA to employees (though you may). If you do have employees, you can still open a personal HSA as long as you are enrolled in an HDHP and meet all other requirements.

Self-employed people can deduct HSA contributions as a business expense on Schedule C (Form 1040), separate from the standard HSA deduction. This can lower your self-employment tax as well as your income tax. Keep records of your HDHP enrollment and HSA contributions in case of an audit.

Frequently Asked Questions

Can I open an HSA if my employer does not offer one?

Yes. You can purchase an HDHP on the individual market or through the ACA marketplace and open an HSA at a bank, credit union, or investment firm. You do not need your employer's involvement. Many people use this route when their employer offers only traditional plans or when they are self-employed.

What happens to my HSA if I change jobs or lose HDHP coverage?

Your HSA stays yours. The money does not disappear, and you do not lose access. However, you cannot make new contributions for months when you are not enrolled in an HDHP. You can withdraw money for medical expenses anytime, and after age 65 you can withdraw for any reason (though non-medical withdrawals are taxed as income).

Can I have an HSA if my spouse is on Medicare?

Yes, if you are not on Medicare and you are enrolled in an HDHP. Your spouse cannot contribute to an HSA once enrolled in Medicare, but that does not affect your may be able to access. You can have separate HSAs if you are both on individual HDHPs and neither is on Medicare.

Do I lose HSA may be able to access if I go on my spouse's health plan?

Only if your spouse's plan is not an HDHP. If your spouse has a traditional PPO or HMO, you lose HSA may be able to access the month you enroll in their coverage. If your spouse's plan is also an HDHP, you can continue contributing to your HSA.

What if I enroll in an HDHP partway through the year?

You can contribute to an HSA only for the months you are actually enrolled in an HDHP. If you enroll on July 1, your contribution limit for that year is reduced proportionally — you can contribute for seven months instead of twelve. Your HSA provider can tell you your exact limit based on your enrollment date.
