I got an e-mail this morning claiming to be from HMRC saying I was entitled to a refund of over £500. I was a bit puzzled by this as I've already had a refund from them this year. I was also suspicious as did not come on any headed paper or have any contact details on it and said you had to click a link and fill out an application form to claim the refund, which is not the usual behaviour of a Government Dept I don't think!
I looked on the HMRC website and it confirms it is a hoax. I also see from googling that it's been about a while, but for those who don't know about it already (like me!), don't open the link if you get one of these.
