Connects to IRS Rev. Proc. 2026-35 figures for tax years 2026 and 2027. Muse can pull brackets by filing status, standard deduction amounts including age and blindness extras, and other inflation-adjusted figures, then estimate federal income tax with a bracket-by-bracket breakdown and a year-over-year comparison.

Example request: "What would my federal income tax be in 2027 if I file married jointly with $140,000 of income?"
