The number of people reaching their qualifying state pension age with more than their required years of state pension contributions had risen by 70,000 to 430,000 in the tax year 2010 to 2011.
In total, 6.2 million people were still paying NICs despite achieving a full entitlement in 2008-9, figures show. They paid £10.6billion in 2008-9 – the latest tax year for which estimates are available.
This equates to £32 a week per person and is likely to have risen substantially in the most recent tax year, since the Government has dropped the number of years of contributions needed for a full pension to 30 from 44. The figures were revealed in a reply to a parliamentary question to Pensions Minister Steve Webb.
Pensions expert Tom McPhail, from pension investors Hargreaves Lansdown, said the system was “fundamentally dishonest”.
