IT Contractors in the UK right now are facing demands to pay retroactively for tax stretching back over a decade in some cases that they purposefully avoided at the time using a scheme called EBT (or, being paid in loans by a trust because loans aren't taxed). They had advice at the time that these schemes were legit (though every adviser would deliver that with a wink), any adult human must have known there was a large risk HMRC would disagree eventually (just as Apple knew they were running a risk), and now they face demands to pay the tax they failed to pay in the first place. Are they the victims? Certainly they will tell you so. Sympathy I have for them? Nil.
