UK Tax System Shift: Top Earners Now Pay More Without Rate Hikes

The top income tax bracket in the UK is now contributing significantly more revenue than in the post-financial crisis era, despite no dramatic tax rate increases. This shift is largely attributed to the erosion of tax thresholds, meaning more individuals are pulled into higher tax brackets as wages rise and inflation increases.

Introduced in 2010 at 50% on income over £150,000, the top tax rate has seen its threshold remain largely static in real terms. While the rate was reduced to 45% in 2013, the £150,000 threshold was not adjusted for inflation. This meant that as salaries grew, more people entered this bracket. The situation was exacerbated by high inflation following the pandemic, and in 2023, the threshold was lowered to £125,140.

Consequently, the top 3% of UK income taxpayers now account for 12% of all income tax revenue, a substantial increase from 6% in 2010. This group now pays £100 billion more annually than in the period after the financial crisis. The real value of the £150,000 threshold from 2010 is now equivalent to approximately £240,000.

While some high-profile individuals have relocated to countries like Greece, more common responses to increased tax burdens include larger pension contributions, charitable donations, and asset transfers to family members to mitigate inheritance taxes. These actions reduce tax collection without individuals leaving the country, complicating government financial planning.

This trend mirrors the situation in Israel, where the top 10% of earners pay 63% of direct taxes while accounting for 46% of income. The article notes that the highest earners in Israel, particularly those with income from capital, may pay a lower effective tax rate than other high earners due to the tax structure. The UK's experience over 15 years offers a case study for ongoing debates in Israel regarding tax brackets, capital gains, and threshold freezes.
