How these numbers were calculated
The headline $100,000 single-filer figures start from 2026 federal income tax brackets and FICA (Social Security + Medicare) withholding, then apply Iowa's own flat 3.80% rate sourced from its Department of Revenue's published 2026 schedule -- we do not estimate or interpolate bracket boundaries.
Corpus rankings (shown above) compare Iowa against the same computed figure for every other state and D.C., recalculated the same way for all 51 jurisdictions so the comparison is apples-to-apples.
