How to read this sheet

Questions

What are the 2026 HSA contribution limits?

$4,400 for self-only HDHP coverage and $8,750 for family coverage, plus $1,000 if you are 55 or older by the end of the year. The IRS set them in Rev. Proc. 2025-19.

Which 2026 figures are set by statute and never move with inflation?

The HSA age-55 catch-up ($1,000), the estimated-tax high-income AGI threshold ($150,000 ($75,000 if married filing separately)), the estimated-tax de-minimis amount ($1,000) and the dependent-care FSA limit ($7,500 ($3,750 if married filing separately)). None of them is indexed.

How do I cite one figure from this page?

Every row has its own anchor: the registry id in the left column is the fragment, so https://thresholds.pages.dev/numbers/2026/#hsa-limit-self-2026 links to that one line. The copy button on each row copies the threshold, the value, the effective period and the source URL as a single line.
