Victims of the tax blunder which will see 1.4 million people asked to pay cash back to the taxman may qualify for increased benefits to soften the blow.
Beleaguered government department HM Revenue & Customs (HMRC) is facing fresh anger as its helpline for tax credits renewals is jammed, with some benefit recipients unable to get through for two weeks.
A whopping 1.4 million taxpayers will be asked to pay an average £1,400 back because they've been charged too little tax after an HM Revenue & Customs (HMRC) blunder.
Many of the nearly six million people who paid too much or too little income tax will find out today whether they are due a rebate or have to make additional payments.
