Contractor & IR35 Take-Home Calculator

Overview

Contract rates are often quoted differently inside and outside IR35, so a straight comparison of day rates can mislead. This workbook takes each rate through every deduction to show what actually reaches your bank account – and what goes into your pension – for a full year.
