National Insurance contributions are due to go up by 1.25 percentage points next month as consumers face mounting cost-of-living pressures.
The tax rise will come on top of soaring energy bills and escalating UK inflation, which has now reached a fresh 30-year high of 5.5%.
However, despite the National Insurance decision causing a row in Westminster, with some Conservative MPs calling on Prime Minister Boris Johnson to drop or at least postpone the increase, a survey of 1,050 British adults has found that 31 per cent of people do not know very much about the tax rise and 12 per cent know nothing about it.
