'Get off your backsides' and register to avoid a fine over child benefit, HMRC boss tells 200,000 higher rate taxpayers - Telegraph
Hundreds of thousands of higher rate taxpayers who have claimed child benefit need to “get off their backsides” and register for self-assessment by tomorrow to avoid a fine, the head of HM Revenue and Customs has said.
Yeah muppet if you did your job you would know who they were.

Of course they could have incorrectly asked to de register, or have incorrect amounts added to their tax code by some not fit for purpose department.

DOH!
