Not everyone can open a Health Savings Account — you must be enrolled in a high-deductible health plan and meet income and citizenship requirements

To open an HSA, you need three things at the same time: enrollment in a high-deductible health plan (HDHP), no other health coverage that disqualifies you, and U.S. citizenship or permanent resident status. If you have Medicare, Medicaid (with rare exceptions), or a spouse's non-HDHP plan, you cannot open an HSA even if you have an HDHP yourself. The rules are strict because HSAs are tax-advantaged accounts — the IRS enforces who gets to use them.

Your HDHP is the gatekeeper. The plan itself must meet IRS minimum deductible amounts, which change each year. For 2024, a self-only HDHP must have a deductible of at least $1,600; a family HDHP must have at least $3,200. Your plan documents will state whether it qualifies as an HDHP. If you are unsure, ask your employer's benefits administrator or your insurance company directly — they know whether the plan meets IRS standards.

Key Takeaways

  • You must be enrolled in an HDHP with a deductible that meets IRS minimums for the year you want to open an HSA.
  • You cannot have Medicare, Medicaid (except in specific circumstances), or other non-HDHP health coverage, even if your spouse has it.
  • You must be a U.S. citizen or permanent resident and cannot be claimed as a dependent on someone else's tax return.
  • Your employer may offer HSA accounts through payroll, or you can open one independently at a bank or financial institution that administers HSAs.
  • You can open an HSA only during the months you are actually enrolled in an HDHP, not before or after.

The HDHP requirement: what counts and what does not

Your health plan must be designated as an HDHP by your employer or insurer. This is not something you decide — the plan either meets IRS rules or it does not. The deductible threshold changes yearly. In 2024, self-only coverage requires at least $1,600; family coverage requires at least $3,200. Out-of-pocket maximums also have IRS limits: $8,050 for self-only and $16,100 for family in 2024. Your plan documents or benefits summary will state these numbers.

Plans that do not count as HDHPs include most employer plans with low deductibles, HMOs without HDHP designation, PPOs that do not meet the deductible floor, and any plan that covers preventive care with a copay instead of after you meet the deductible. Some employers offer both HDHP and non-HDHP options — you must choose the HDHP to open an HSA. If your plan is not labeled as an HDHP, you cannot use it as the basis for an HSA.

Coverage that blocks you from opening an HSA

Even if you have an HDHP, certain other coverage makes you ineligible. Medicare is the biggest barrier — once you enroll in any part of Medicare (Part A, B, C, or D), you cannot open a new HSA or contribute to an existing one. If you already have an HSA when you turn 65 and enroll in Medicare, you can keep the account and withdraw money tax-free for may have access to medical expenses, but you cannot add new contributions.

Medicaid also blocks HSA may be able to access in most cases, though some states have carved-out programs that allow it. If you are on Medicaid, check with your state's Medicaid office or your HSA provider to confirm whether your specific coverage disqualifies you. Medicaid and HSA rules vary by state.

Coverage through a spouse's non-HDHP plan disqualifies you, even if you also have your own HDHP. The IRS rule is strict: you cannot have any non-HDHP coverage at any point during the month you want to contribute. If your spouse is on a traditional PPO or HMO, you cannot open an HSA. Your spouse can have an HDHP and their own HSA, but your coverage must also be HDHP-only.

Certain other coverage also blocks you: TRICARE (military health coverage), Veterans Affairs coverage, Indian tribe health plans, and some workers' compensation plans. If you have any of these, you are not may be able to access for an HSA.

Citizenship and tax filing status

You must be a U.S. citizen or a permanent resident (green card holder). Temporary visa holders, undocumented immigrants, and non-residents cannot open an HSA. You will need to provide proof of citizenship or permanent resident status when you open the account — typically a Social Security number, which the HSA provider will verify with the IRS.

You also cannot be claimed as a dependent on someone else's tax return. If your parents or another person claims you as a dependent, you are ineligible, even if you have your own income and an HDHP. This rule applies most often to adult children living at home or full-time students whose parents claim them.

When you can and cannot open an HSA

You can open an HSA only during the months you are enrolled in an HDHP. If you enroll in an HDHP on March 1, you can open an HSA in March. If you drop the HDHP on June 30, you cannot open a new HSA in July. This timing rule matters if you are switching plans mid-year or starting a new job with HDHP coverage.

There is one exception: if you enroll in an HDHP during the annual open enrollment period (usually November through December for coverage starting January 1), you can open an HSA in January even though you enrolled in December. The IRS allows this grace period for annual enrollment.

Once you open an HSA, you can keep it and continue to contribute as long as you remain enrolled in an HDHP. If you switch to a non-HDHP plan, you stop being able to contribute, but you keep the account and can withdraw money for medical expenses tax-free.

Where to open an HSA if you are may be able to access

Many employers offer HSA accounts through payroll, often paired with their HDHP option. If your employer offers one, you can enroll during open enrollment or when you first become may be able to access. The employer may contribute to your account, and contributions come out of your paycheck pre-tax.

If your employer does not offer an HSA, or if you are self-employed or have individual HDHP coverage, you can open an HSA at a bank, credit union, or financial services company that administers HSAs. Common providers include Fidelity, Lively, HealthEquity, and many regional banks. You will need to provide proof of HDHP enrollment (usually a copy of your plan documents or an enrollment confirmation from your insurer) and proof of citizenship or permanent resident status.
