The company, which publishes the Daily Mirror, Scottish Daily Record and Sunday People as well as 260 regional newspapers, last week outlined a three-phase plan to revitalise and grow its business.
Speaking as Trinity Mirror announced its half yearly results last week, the group's chief executive Sly Bailey said "significant" savings would be made in all areas, with IT, finance and human resources coming under the spotlight first.
A spokesman for Trinity Mirror said the centralisation of the company's IT operations would be key to achieving the savings outlined by Bailey. "In the past, we feel more effort could have been made in areas such as IT, where we have economies of scale," he said.
"Expert functions, such as IT, have been managed by individual businesses. We want to centralise so we can maximise benefits of scale."
Trinity Mirror has also announced plans to cut 550 jobs across all areas of the business, and these will include IT staff, the spokesman confirmed.
