Economics Snapshot - The Impact of Tax and Benefits on Inequality

Progressive income tax and cash welfare benefits help to reduce the gap between the richest and poorest households in the UK. In 2007/08, original income (before taxes and benefits) of the top fifth of households in the UK was £72,600. This is approximately 16 times as great as the figure of £4,700 for the bottom fifth. After taking account of all taxes and benefits, the top fifth had an average final income of £52,400 per year compared with £14,300 for the bottom fifth of households, a ratio of four to one.

The latest figures for the impact of tax and benefits on the UK income distribution reveal the importance of cash benefits such as Income Support, Pension Credit, Child Benefit, Incapacity Benefit and Retirement Pension as a means of redistribution. play a major role in reducing income inequality. Of the total amount of cash benefits received, the bottom two quintile groups together receive 57 per cent. Cash benefits represent around 58 per cent of gross income for the bottom quintile group and 36 per cent for the second quintile group, falling to 2 per cent for the top fifth of households.

Direct taxation, with the exception of Council tax and Northern Ireland rates, is progressive; that is households at the lower end of the income distribution pay smaller proportion of their income in direct tax compared with higher income households. As a proportion of their gross incomes, households in the bottom quintile group pay an average of 11 per cent in direct taxes compared with 25 per cent for those in the top quintile group.

In contrast indirect taxes are found to have a regressive effect on the final distribution of income. Overall the latest figures from the ONS find that income inequality in the UK in 2007-08 was little changed from the year before. This BBC news article provides more background.
