And what about type rating costs being used to off set tax through the pseudo company? Is this true? If so that's a pretty big claim back for HRMC in its self.
As said, HRMC are quite happy to go after individuals, and they don't let go....ever. They'll probably investigate a couple then issue demand to the rest, with the onus to provide evidence that self employed status is justified. Providing your services to more than one company is a pretty big part of it. Hopefully this'll be the end of this, frankly, shoddy practice
