The tax burden in the UK is now at a 50-year high: taxes reached 34.6 per cent as a proportion of GDP in 2018-19, the highest level since 1969-70. Whilst efforts have been made to lower the amount of direct taxes that are paid by the poorest, such as by increasing the personal allowance, the burden of taxes falls disproportionately on those who can least afford it.
New data out today shows this alarming trend in fuller detail. In real terms, the bottom 10 per cent of households paid £5,471 in direct and indirect taxes in 2017-18, or 47.6 per cent of their gross income. Whilst there have been fluctuations over the last 10 years, this represents a 10.2 per cent increase as a proportion of gross income from 2008-9.
- The bottom 10 per cent of households lost 43.2 per cent of their gross income to taxes in 2008-9. In 2017-18, that had risen to 47.6 per cent.
- In real terms, the poorest 10 per cent of households paid £4,409 in direct and indirect taxes in 2008-9. In 2017-18, this had risen to £5,471.
- The top 10 per cent of households lost 32.9 of their gross income to taxes in 2008-9. In 2017-18, that had risen to 33.5 per cent.
- Between 2008-9 and 2017-18, the poorest tenth of households on average lost 45.6 per cent of their gross income through taxes. The richest 10 per cent had 33.9 per cent of their gross income taken through the tax system over the same period.
- Across all households, 33.8 of gross income was lost to taxes in 2008-9. In 2017-18, this was at exactly the same level.
- On council tax, the bottom 10 per cent of households have seen the amount paid rise from £852 to £914 in real terms, an increase of 7.3 per cent. For the top 10 per cent, the change has been 4 per cent less in real terms.
