Ministers are to set out precise details of the additional contributions facing millions of doctors, nurses, teachers and civil servants.
According to leaked details obtained by the Daily Telegraph, while 750,000 of the lowest paid staff face no increase, the remaining five million in pension schemes will be hit, with the top earners paying the most.
In the first year, the best-paid 40,000 public sector workers, earning well over £100,000, will pay an additional £284 a month - £3,400 a year - for their final salary schemes. The paper said that a doctor on £100,000 a year would pay almost £2,000 a year more.
For staff in the £50,000 pay bracket, those working in the NHS would pay £768 a year extra. Workers with a £35,000 salary will have to find an extra £516 a year while those on £21,000 a year will pay an additional £108 a year.
The paper said further increases will be introduced until 2015 so that the overall extra contributions rise to almost £3bn a year, accounting for an average 3.2% of each worker’s gross salary before tax.
The paper said that the figures show that when tax is taken into account, a nurse on £25,000 would be only £12 a month worse off, whereas a hospital consultant on £130,000 a year will have to pay £160 a month extra.
