OK, my friend - the same one as previous post - is self employed but has only one employer. (Works for Oxford University in regular job as well on PAYE etc) He invoices this guy every month. I quizzed him a little while about his tax and NI as a self employed person and he told me that his "boss" paid it on his tax returns.
Now, I know that the construction industry works like this and I know that if you are self emplyed with only one employer things are slightly different but what has happened is that now it looks like his boss has not paid his TAX/NI (ever!)
Does any tax experts out there know if there is any reason for my friend to think his boss would pay these things? Or if, as I suspect, he has got a serious problem on his hands, any idea what he should do.
