Capita Self Invested Pensions (CSIP) has told 520 staff their jobs are potentially at risk in a bid to cut costs.
The decision follows a review of the firm's operations as market conditions force it to drive further efficiencies in the business.
A total of 520 jobs are at risk across the firm's Salisbury and Mumbai offices, but it cannot say how many of its staff will be made redundant.
However, it expects axe less than 100 jobs in Salisbury.
Staff at CSIP's Salisbury office were informed of the streamlining exercise on 30 June and a consultation process will begin on 15 July to cut the number of staff in both locations.
