Question: I am aged 73. I became eligible for state pension when I was 65 but chose not to take it at that point because I was in full-time employment and already paying the higher rate of income tax. I retired completely from employment when I was 68 and then chose to take my state pension, which —with my work pension — meant that I was on the lower rate of income tax. However, when I was 70 I started working part-time. This now means that I am in the bizarre situation of effectively paying the higher rate of income tax on a minimum wage. Can I defer my state pension again temporarily.

Answer: For most people their state pension forms a valuable foundation for their income in retirement. Those who claim the new state pension could be receiving over £12,540 a year.

But the state pension is now hovering just slightly under the frozen personal allowance – the salary level over which people pay income tax – of £12,570.
