HMRC have sent a man in Bristol a tax demand for £14,301,369,864,489.03. This is double the size of the UK economy. He thinks it would take him 369 million years to pay off the bill using his salary.
An HMRC employee has conceded that it looks as if somebody fell asleep on the keyboard when they were getting his new tax coding notice ready.
The thing I like best about this story is the .03 at the end of the £14 trillion sum. Nothing like absolute accuracy!
