When do end-clients have to and not have to determine IR35 status?

[JohntheBike]

Is it a large client you are working with? I imagine HMRC are targetting large companies with a large number of contractors for a potentially large return for them

Anyone who strongly disputes an inside IR35 assessment through the disputes process and fails to overturn that assessment, should lodge a claim in the ET. Even if there were to be some behind the scenes horse trading with such large companies, as there was with Susan Winchester and apparently was attempted in the Alcock case, this might just sober clients up to adopting the approach that they will be required to take by law and assess each contract individually. But then that's a big ask.

Anyone have any news on the ET case IPSE is supporting? We should be hearing the judgement in the Alcock case soon, unless there has been some political skulduggery
