"The HMRC statement not to renew the contract attacks our professional credibility, and the commitment of our staff who have performed determinedly, despite the issues with HMRC policies and procedures," said a spokesperson. Concentrix won a £75m contract to try to save the government more than £1bn in incorrect or fraudulent tax credit payments in May last year.
