Gross to Net report

The 'gross' column with sub-columns 'total' and 'taxable' is misleading where they are salary sacrifice pension deductions. If someone earns £2000 gross and has a pension ded of £500; I would expect the columns to read 'total' £2000 and 'taxable' £1500. Currently this would show as gross total & taxable £1500.Would be great if this could happen
