HMRC gives ebay traders a chance to hand themselves in. And electricians too!
Contrary to popular belief the people at HMRC are actually very kind.
Yes, they chase you down when you don't pay your taxes, and yes, they can make you pay massive penalty fines – or even bang you in prison if you're a serial offender! But they also regularly give you a chance to hand yourself in when your dealings have not been quite ... above board!
