Every figure in Ignis Tools comes from 2026 law — IRS Rev. Proc. 2025-32 and 2025-25, CMS, HHS, SSA, the OBBBA statute and each state’s own sources — and from calculation code tested against values worked out by hand.
This page lists those sources with the date each was checked, how the tests gate every deploy, the assumptions every tool shares, what each of the nine tools models and leaves out, how state income tax is handled, and a dated log of the errors we have corrected.
