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, you are not claimed as a dependent on someone else's tax return, and you are not enrolled in Medicare. The HDHP itself is the gateway — without it, you cannot open an HSA, regardless of your income or employment status.

The IRS sets the deductible thresholds that define an HDHP each year. For 2024, an HDHP must have a deductible of at least $1,600 for individual coverage or $3,200 for family coverage. Your employer or insurance marketplace will tell you whether your plan qualifies. If you are unsure, check your plan documents or ask your benefits administrator directly — they can confirm the deductible amount in writing.

Key Takeaways

  • You must be enrolled in a High Deductible Health Plan to open an HSA; no HDHP means no HSA, regardless of income.
  • You cannot have other health coverage at the same time, including coverage through a spouse's plan or Medicaid, with limited exceptions for specific plans like dental or vision.
  • You cannot be claimed as a dependent on someone else's tax return or enrolled in Medicare, even if you have an HDHP.
  • Self-employed people, part-time workers, and those between jobs can all open HSAs as long as they have an HDHP and meet the other conditions.

What "No Other Health Coverage" Actually Means

The rule against other coverage is strict but has exceptions. You cannot be covered by a spouse's health plan, a parent's plan, Medicaid, or most employer plans at the same time you hold an HSA. However, you can have dental insurance, vision insurance, accident insurance, disability insurance, long-term care insurance, and workers' compensation without losing HSA may be able to access. You can also have coverage for specific conditions like cancer or hospital indemnity plans.

If you are married and your spouse has a traditional health plan, only one of you can have an HSA — the one with the HDHP. If both spouses have HDHPs, each can open their own HSA. If you lose other coverage during the year — for example, your spouse's employer plan ends — you can open an HSA mid-year, though you will need to track which months you were may be able to access to make contributions.

Employment Status Does Not Disqualify You

You do not need to be employed full-time to open an HSA. Self-employed people with an HDHP can open one. Part-time workers can open one. People between jobs can open one if they have an HDHP through the marketplace or COBRA. Retirees under 65 can open one if they have an HDHP. The only employment-related rule is that your employer cannot prevent you from opening an HSA if you are enrolled in their HDHP — they may offer one through payroll, but you can open one independently at a bank or financial institution instead.

If you are self-employed and buy your own HDHP through the marketplace, you are may be able to access to open an HSA. The same applies if you buy coverage during open enrollment or a special enrollment period. The plan itself must meet the HDHP definition; the source of the plan does not matter.

Age Limits and Medicare Enrollment

You can open an HSA at any age as long as you are not enrolled in Medicare. Once you turn 65 and enroll in Medicare Part A, you can no longer make new contributions to an HSA. However, you can continue to withdraw money from an existing HSA for may have access to medical expenses at any age without penalty. If you delay Medicare enrollment past 65, you can continue contributing to an HSA as long as you remain unenrolled and have an HDHP.

If you are approaching 65, you have a choice: enroll in Medicare and stop HSA contributions, or delay enrollment and keep contributing. Some people delay Medicare specifically to continue building HSA savings. Be aware that delaying Medicare Part B past your initial enrollment window can result in permanent premium penalties, so weigh the HSA benefit against the Medicare cost before deciding.

Dependent Status and Tax Filing

You 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 to adult children claimed by parents, not just minors. If you are 26 or older and your parents still claim you as a dependent, you cannot open an HSA until that changes. Once you file independently, you become may be able to access.

If you are married and file jointly, both spouses can have HSAs if both have HDHPs and neither is claimed as a dependent. The dependent rule is about your own tax status, not your spouse's or children's status.

Special Situations: COBRA, Marketplace Plans, and Tribal Coverage

If you are on COBRA continuation coverage and your COBRA plan is an HDHP, you can open an HSA. COBRA does not disqualify you — the plan type is what matters. Similarly, if you buy an HDHP through the marketplace during open enrollment or a special enrollment period, you can open an HSA when ready. You do not have to wait for coverage to begin; you can open the account as soon as you enroll in the plan.

If you are a member of a federally recognized Indian tribe, you have additional options. Certain Indian Health Service plans and tribal health plans are treated as HDHPs for HSA purposes, even if their deductibles are lower than the standard HDHP threshold. If you have coverage through an Indian tribe, contact the IRS or your tribal health administrator to confirm whether your plan qualifies.
