Sole trader 18600 gross profit after deductions is beyond si

I was under the impression that it was gross before expenses but it's £18600 after expenses . I've re read the paragraph and it it is indeed gross income after tax. I find this absolutely RIDICILOUS as how on earth are the employed allowed to use their annual gross salary without tax deductions whereas the sole traders have to show the figure after all deductions and personal allowance. Beyond ridiculous. Well that's made things extremely hard now.

Please continue in your other thread to avoid several threads discussing the same issue.
