One million people to receive new tax demands - Telegraph

One million people to receive new tax demands - Telegraph: "They will be told they have underpaid or overpaid after HM Revenue & Customs made errors on their tax codes.
The victims will join nearly six million people sent revised demands last year after a new computer system picked up on the errors dating back to 2008.
A Government insider told The Sun newspaper: 'At least one million more will learn they too are on the wrong tax code. Some have overpaid and some have underpaid. It is another tax fiasco.'
Last year, HMRC admitted it had got the tax of 5.7 million people wrong since 2008.
Of those, 1.4 million taxpayers had paid too little and had to pay an average of almost £1,500 each, while an extra 4.3 million pocketed rebates averaging £419."
