Yeah, @mark65 You've got to love the tool that assesses and produces a judgement regarding your IR35 status; to help HMG depts. make the correct judgement....so that the can ignore it because its not the right answer....
I'm pretty sure its crapness (low bar) was the get out of jail free card provided by HMRC to both departments (and therefore contractors) after a clueless attempt at a vote winning ministerial announcement (he won't do that again, er) to prevent the mass exodus of contractors from the public sector and collapse of GDS principles (and therefore GDS).... but in true HMG gov. style depts. are actively ignoring that outstretched arm and have decided to fall of the cliff instead.......Nailed it!!
