For years, “HSA-eligible” basically meant “true HDHP.” That locked a lot of Exchange bronze and catastrophic enrollees out of HSA contributions even when their coverage was high-deductible in spirit.
Under the One Big Beautiful Bill Act, as clarified in Notice 2026-5, bronze and catastrophic plans are treated as HSA-compatible beginning January 1, 2026 — and the IRS clarified they do not have to be purchased on an Exchange to get that treatment, as long as they are bronze or catastrophic plans of the relevant type.
Why TPAs and employers care
If you sponsor an ICHRA (or are exploring one), employees shopping individual coverage suddenly have a clearer path to pair a bronze/catastrophic policy with an HSA. That changes how you talk about account-based benefits during ICHRA education sessions.
If you stick with a traditional group HDHP, this may not rewrite your plan design — but it does change the competitive landscape and the questions HR will field from dual-income households comparing options.
Talking points for January conversations
- HSA eligibility still fails if the person has other disqualifying coverage (a general-purpose health FSA is still the classic example).
- Contribution limits for 2026 remain $4,400 / $8,750 (plus catch-up).
- Don’t promise HSA eligibility from a screenshot of a plan name alone — confirm plan category and other coverage.
This is one of those quiet statutory shifts that won’t trend on social media but will show up in employee “why can’t I open an HSA?” tickets all year.
