The Liberal Democrats say increasing income tax would raise more than £100 million for the people of Sheffield.
The party today announced its plan to raise more money for the NHS and social care services by adding a penny onto every pound of income tax people pay.
The tax, the Lib Dems say, would raise £103.7 million for Sheffield each year - £84 million for the NHS and £19.7 million for social care.
The party also plans to set out a five point recovery plan for the NHS and social care in its manifesto.
Nick Clegg, who is trying to keep is Sheffield Hallam seat, said: "Right now in Sheffield we are seeing patients lying on trolleys in hospital corridors, urgent operations being cancelled and the elderly being denied the care they need.
"The Liberal Democrats are prepared to be honest with people and say that to secure the future of the NHS we will all need to chip in a little more.
"A penny in the pound would allow us to invest in improving local NHS services and ensuring the elderly receive the care they deserve.
"This Conservative government has left our health and care services under serious pressure - and while the crisis gets worse they just don't seem to care.
"We cannot continue asking the system to deliver more and more, without giving it the resources to do so."
Liberal Democrat health spokesman and former health minister Norman Lamb added: “The NHS was once the envy of the world and this pledge is the first step in restoring it to where it should be.
“A penny in the pound to save the NHS is money well spent in our view.
“But simply providing more money on its own is not enough and that’s why this is just the first step in our plan to protect health and care services in the long-term."
