According to Hargreaves Lansdowne, a financial services firm, an employee on £25,000 will pay an extra £270 a year in national insurance. For someone paid £40,000, the increase will be £481.
Large organisations, including the NHS, will also have to increase their employer’s national insurance contributions by as much as 3.4p in the pound.
The biggest beneficiaries of the flat-rate pension will be part-time workers, carers and people who take time out of work to bring up their children. The self-employed could also gain. But some higher-paid workers will get a smaller state pension than they would have received under current rules.

Employers who offer final salary pensions face much larger increases in their national insurance payments.
For each worker paid £25,000, an employer could have to contribute an extra £657. For a worker paid £40,000, the employer’s increase will be £1,168.
Those costs have led to warnings that many of the 6,300 or so remaining final salary schemes in the private sector will be forced to close.

the political elite of all three parties really do hate pensioners and their pensions.
