What the 2026 OBBBA law actually changed for HSAs
The One Big Beautiful Bill Act (Pub. L. 119-21, signed July 4, 2025) made three real HSA changes — and left several widely-rumored ones on the cutting-room floor. Here's the accurate, apolitical version.
The three enacted changes
All three amend Internal Revenue Code §223, with interim IRS guidance in Notice 2026-5:
1. Bronze and catastrophic Exchange plans now count as HDHPs
For months beginning after December 31, 2025 (so, effectively 2026), individual bronze and catastrophic plans available through the Exchange are treated as HSA-qualifying high-deductible plans. The important qualifier: they must be Exchange-available individual coverage. "Any bronze plan qualifies" is wrong — SHOP and small-group bronze plans do not, and catastrophic coverage is still limited to people under 30 or those with a hardship exemption. If you buy a marketplace plan, this is worth checking against your subsidy math (see acacalc.com).
2. Direct Primary Care is compatible — up to a fee cap
Also effective for months beginning after December 31, 2025, a Direct Primary Care (DPC) arrangement no longer automatically disqualifies you from HSA eligibility. But there's a hard cap: a DPC fee over $150/month for an individual or $300/month becomes disqualifying coverage — meaning you lose HSA eligibility entirely, not just a reimbursement cap. Those dollar caps are indexed after 2026, so the 2026 figures are a point-in-time value.
3. The telehealth safe harbor is permanent — and it's not new for 2026
The provision letting an HDHP cover telehealth before you meet the deductible without breaking HSA eligibility is now permanent. Note the effective date: it applies retroactively to plan years beginning after December 31, 2024 — that is, 2025 — so treat it as already in effect, not as a 2026 novelty. Many summaries mislabel this as a 2026 change.
The Senate stripped several House provisions that circulated widely. None became law: doubled contribution limits for lower-income filers; letting Medicare Part A seniors contribute (this is why the $0-on-Medicare rule still stands); HSA eligibility despite a spouse's general-purpose FSA; pooling both spouses' catch-ups into one HSA; gym/fitness memberships as qualified expenses; and FSA/HRA-to-HSA conversions. Also — the OBBBA "Trump Accounts" are child investment accounts, not health accounts; don't conflate them with HSAs.
What this means for your 2026 planning
The practical upside is broader eligibility: if you're on a bronze Exchange plan or use a modest DPC membership, you may now be able to open and fund an HSA where you couldn't before. The practical caution is that the biggest rumored expansions — especially Medicare-senior contributions — did not happen, so the high-stakes Medicare rules are unchanged. The 2026 dollar limits themselves ($4,400 self-only, $8,750 family, $1,000 catch-up) come from IRS Rev. Proc. 2025-19, not from OBBBA.

Reflects current federal law as of June 1, 2026. The three HSA provisions are enacted under Pub. L. 119-21 (signed July 4, 2025) with interim guidance in IRS Notice 2026-5, whose comment period closed March 6, 2026 — DPC "primary care" definitions and bronze/catastrophic mechanics may be refined on finalization. The DPC $150/$300 caps index after 2026. Verify current status on congress.gov and with the IRS. This guide is educational, not advice; see our disclaimer.
