KPMG has begun a consultation on reducing pensions contributions, affecting around 20% of staff if agreed on, Professional Pensions finds.
The audit giant told PP it was consulting on a "proposed temporary change" to employer contributions as it looked to offset the financial damage caused by the Covid-19 pandemic.
A spokeswoman said: "We are operating in highly volatile times and are proposing a series of actions to safeguard out business in the medium and long term.
"At this stage, no final decision has been made."
KPMG is also discussing the potential cutting of up to 100 positions across its consulting business due to the changing demand of clients as a result of coronavirus.
The spokeswoman said: "As a result of the Covid-19 pandemic, we have seen a change in demand in some areas of our internal support provision, and as a result, we are proposing to make fewer than 100 roles within our business services function redundant.
"Our consulting practice employees more than 3,000 people and is continuing to see high demand for a range of core services such as digital transformation, supply chain management and cyber security."
This follows a programme of work started at the auditor last year to analyse its internal business services functions.
The spokeswoman said: "That work was undertaken with long-term sustainability in mind, but it has also proved integral to the resilience our firm has shown in the last few months."
The Financial Conduct Authority (FCA) has issued a warning after its website was copied onto a spoof domain.
