Who is eligible for a Health Savings Account (HSA)?

Not everyone qualifies for a Health Savings Account (HSA). Eligibility is determined by a specific set of IRS rules tied to your health coverage, tax status, and other factors.

This guide explains who is eligible to open and contribute to an HSA, common disqualifiers, and important exceptions many people overlook.

The four IRS requirements for HSA eligibility

To be eligible for an HSA, you must meet all four of the following conditions:

1. You are enrolled in an HSA-qualified high-deductible health plan (HDHP)
2. You have no other disqualifying health coverage
3. You are not enrolled in Medicare
4. You cannot be claimed as a dependent on someone else's tax return

1. You must be enrolled in a qualified HDHP

HSAs are only available to individuals covered by a high-deductible health plan (HDHP) that meets IRS requirements. Not all high-deductible plans qualify.

For plan years beginning in 2026, an HSA-qualified HDHP must meet the following limits:

Always confirm that your plan is officially designated as HSA-qualified. A high deductible alone does not guarantee eligibility. If you are new to the rules, see what qualifies as an HDHP.

For plan years beginning after Dec. 31, 2024, an HSA-qualified HDHP may cover telehealth and other remote care services before the deductible without disqualifying HSA eligibility, as long as the plan remains otherwise HSA-qualified.

2. You cannot have other disqualifying health coverage

You generally cannot have additional health coverage that pays for medical expenses before you meet your HDHP deductible.

Common examples of disqualifying coverage include:

• A spouse's non-HDHP health plan that covers you
• A general-purpose health FSA
• Most employer-sponsored HRAs that reimburse medical expenses before the deductible

Other permitted coverage, such as dental, vision, accident, disability, and specific disease coverage, also does not make you ineligible. For a deeper comparison, see HSA vs FSA vs HRA.

3. You cannot be enrolled in Medicare

Once you enroll in Medicare, you are no longer eligible to contribute to an HSA. This includes Medicare Part A, Part B, and Medicare Advantage.

You may continue using existing HSA funds after enrolling in Medicare, but new contributions are not allowed.

4. You cannot be claimed as a dependent

If another taxpayer can claim you as a dependent, you are not eligible to contribute to an HSA, even if you are enrolled in an HDHP. This scenario commonly affects students and young adults.

Special rule for veterans

VA benefits do not automatically disqualify you from contributing to an HSA. The key issue is whether you receive VA medical care for a condition that is not service-connected.

• If you receive VA care for a service-connected disability, you can still be HSA eligible.
• If you receive VA care for a non-service-connected condition, you are not eligible to contribute to an HSA for the next 3 months.

Common eligibility scenarios

Power user tip: the last-month rule

If you become HSA-eligible late in the year (for example, on December 1), the IRS may allow you to contribute the full annual maximum for that year.

Because eligibility is determined month by month, even a small coverage change can have tax consequences. If you are planning contributions, see HSA contribution limits.
