Health Savings Account (HSA)
Content context: plan year 2026
In plain terms
A Health Savings Account (HSA) lets eligible people make tax-deductible or excluded contributions, grow the balance tax-free and take tax-free withdrawals for qualified medical expenses under federal rules. You keep the balance when you change jobs or plans. Contribution eligibility generally requires qualifying coverage and no disqualifying other coverage. Starting January 1, 2026, bronze and catastrophic plans available through an Exchange are treated as HSA-compatible even if they fail the usual HDHP limits; they do not have to be purchased through the Exchange. Medicare enrollment, a general-purpose health FSA, tax-dependent status and other rules can still prevent contributions. Existing HSA funds can still be used for qualified expenses when you cannot make new contributions.
This is an explanation, not an eligibility decision. A plan-year label is not a source-check date. Source for this entry: Read the cited reference.
A plain example
Illustration: you have HSA-compatible coverage and meet the personal eligibility rules, so you contribute within your applicable annual limit. You use $400 for a qualified lab bill. Unspent funds remain yours and roll forward. If you later lose contribution eligibility, the existing balance does not disappear, but new contributions must stop or be adjusted as required.
Why it matters
Separate eligibility to contribute from the ability to spend an existing balance. Compare the plan's premium, network and total costs alongside any federal HSA tax benefit; HSA-compatible coverage is not automatically the least expensive plan.
A common point of confusion
A high deductible alone does not establish HSA eligibility. Traditional HDHP rules remain, but eligible bronze/catastrophic plans have a new 2026 pathway. An HSA is not an FSA, and an otherwise eligible plan does not override Medicare, other coverage or tax-dependent restrictions. Employer and personal contributions share the applicable limit; state tax treatment can differ.
