Fall open enrollment copy is already being drafted. If your 2027 HSA slides still say “TBD” or recycle 2026 figures, replace them with Revenue Procedure 2026-24. The IRS issued the procedure in late May; it appears in IRB 2026-25. The numbers are not breaking news this week — they are the ones employers still need to act on before OE locks.

2027 HSA and HDHP amounts

| Item | 2026 | 2027 | | --- | ---: | ---: | | HSA annual contribution (self-only) | $4,400 | $4,500 | | HSA annual contribution (family) | $8,750 | $9,000 | | HDHP minimum deductible (self-only) | $1,700 | $1,750 | | HDHP minimum deductible (family) | $3,400 | $3,500 | | HDHP out-of-pocket maximum (self-only) | $8,500 | $8,700 | | HDHP out-of-pocket maximum (family) | $17,000 | $17,400 |

The age-55 catch-up remains $1,000 (statutory; not re-indexed in this revenue procedure). 2026 comparison figures are from Rev. Proc. 2025-19.

Direct primary care and excepted-benefit HRAs

Rev. Proc. 2026-24 also addresses two adjacent limits employers ask about in the same OE meeting:

Health FSA salary-reduction and carryover caps for 2027 are not in Rev. Proc. 2026-24. Keep using current guidance for 2026 FSA administration, and wait for the IRS inflation procedure that covers §125(i) before reprinting 2027 FSA election maximums.

Why August matters

Contribution grids, SPD/SBC footnotes, HSA payroll caps, and vendor configuration files get frozen weeks before the first OE meeting. Pair these HSA/HDHP figures with the 10.22% 2027 ACA affordability percentage from Rev. Proc. 2026-26 so finance is not modeling next year’s HDHP employee cost against last year’s rule set.

What employers should do

  1. Update OE worksheets, plan comparison charts, and payroll HSA annual maximums to $4,500 / $9,000.
  2. Confirm 2027 HDHP designs still clear the $1,750 / $3,500 deductible floors and stay at or under the $8,700 / $17,400 OOP caps (embedded family deductible designs need a second look).
  3. If you offer an excepted-benefit HRA, reset the newly available amount to $2,250 for 2027 plan years.
  4. If employees use DPC alongside an HSA, keep communicating the $150 / $300 monthly fee ceilings until a later inflation adjustment says otherwise.
  5. Do not invent 2027 health FSA limits — flag them as pending IRS release.

When those numbers are wrong in the enrollment system, the cleanup is not a typo fix — it is contribution corrections, midyear eligibility noise, and participant trust you would rather not spend October rebuilding.
