Article Preview: Recently retired women could be missing out on a little known concession under the new state pension system. This concession applies to women who paid the ‘married woman’s stamp’ at any time during the past 35 years. An insurer is encouraging newly retired women, and those who are approaching state pension age, to check they are benefiting from this concession. It was designed to ensure women who paid a reduced rate of National Insurance contributions are protected financially in retirement. This concession dates back to the 1940s when the modern welfare state was designed.
