So if HMRC have made a cock up in what we all should of paid.
As i understand it is that its an old thing that noone update to keep things moving with the times.
Dont think anyone should pay anything at all, as its there cock up not ours, like everyone we assume we all paid what was expected to be correct amount to pay.
As most of us before doing w/c was working for some company so might effect some or maybe all of us.
