Scientific Background

Assumptions: user-entered category totals; no mortgage acquisition-debt limits, charitable AGI ceilings, or Pease-like 37% benefit haircut modeled in detail. SALT 2026 cap/phase figures follow OBBBA statutory design with commonly published 1% annual step-ups—confirm on IRS Schedule A instructions if later official tables differ.
