California DE 44 (2026), Method B examples A–F · Rev. 52 (4-26), pages 43–45

Virginia Employer Withholding Instructions, John example · Rev. 05/25, pages 21–22

The printed example rounds annual tax to a whole dollar before dividing. The exact formula with final cents gives $109.48 instead of $109.50; the engine retains the exact formula.
