As i said previously in this thread and about 18 months ago when I first found out about it, HMRC have employed new staff purely to hunt out this kind of evil, tax dodging, illiterate, badly informed scum.
Also, as before don’t stop claiming it, just put it aside and pay back when you get your bill, people’s situations change and according to our accountant it can contribute to a partners ni payments and it can be a real bastard to set back up once cancelled.
