Oh dear
The ruling isn't binding - this is a decision in principle only by the FTT. However, it may well be influential on others whose PSCs operate under similar terms.
Ms Ackroyd won't be paying any tax due - the legislation specifically charges her PSC with the liabiliy, not her.
Also, the quantum has *not* been decided by the FTT. She claims it's about half of what HMRC have assessed. The treatment of corporation tax that has been paid by her PSC is also in dispute.
