An ex Concentrix employee, who was made redundant last week, told the Belfast Telegraph it had been "tough and stressful" for the workforce since the news broke that the contract would not be renewed in 2017.
The Government said Concentrix had "not been providing the high levels of customer service that the public expect and which are required in their contract".
However, the ex employee disagrees:
"I don't agree that it was Concentrix's fault. It's the HMRC's systems - everything needs updated.
They need systems to be able to take on information much quicker.
It takes up to 48 hours. The staff are trained in exactly what they have to do. We worked on behalf of HMRC carrying out compliance checks. Sometimes you would be on the phone, or off the phone working on cases."
The former employee claimed that once staff had dealt with and processed a case, as well as the massive delay, the systems used by the Government body were not up to scratch.
"After we were closing cases off... it then sits in a sort of limbo stage."As ever, views and comments are welcome.
Tax does have to be taxing.
