It's almost never the bracket math — it's that nobody tracked the business expenses. Verticals that handle invoicing, payments, and expense capture in one place (VitalCoach, Horizon, Keyring, DealDesk) hand your accountant a clean P&L instead of a year of bank statements. The deduction column is the lever, and most people leave it empty.
