Rachel Reeves's stealth tax raid explained...in pies

Key Concepts

• Income Tax Brackets: Thresholds at which different tax rates apply to income.
• Higher Rate Tax: A tax rate of 40% applied to income earned above a specific threshold.
• Frozen Tax Brackets: When the income thresholds for tax rates are not adjusted for inflation, leading to more people being pulled into higher tax brackets as their nominal income increases.
• Fiscal Drag: The phenomenon where inflation pushes taxpayers into higher tax brackets, even if their real income hasn't increased.

Income Tax and the "Pie" Analogy

This analysis uses the analogy of a "pie" to explain the impact of income tax on taxpayers, particularly focusing on the higher rate of income tax.

The Shrinking Slice of Take-Home Pay

• Historical Context (1991-92): In the fiscal year 1991-92, only 6% of UK taxpayers paid the higher rate of income tax. This represented a small "slice" of the overall taxpayer population.
• The Higher Rate Tax: This rate means that for every £1 earned above a certain threshold, 40 pence is paid to HMRC (Her Majesty's Revenue and Customs).
• Tory Policy and the Freeze (2021): By 2021, the Conservative government had frozen income tax brackets. This policy led to approximately 15% of taxpayers paying the higher rate.
• Rachel Reeves' Extension of the Freeze: The current Labour leader, Rachel Reeves, has extended this freeze for an additional three years.
• Projected Impact by 2030: It is projected that by 2030, one in four taxpayers (more than 10 million people) will be paying the higher rate of income tax. This signifies a substantial increase in the proportion of the population subject to this higher tax burden.

Impact on Take-Home Pay: A Case Study

To illustrate the effect on individual take-home pay, the analysis considers a hypothetical individual earning £45,000 per year in 2021.

• 2021 Scenario: In 2021, with an income of £45,000, the individual's income tax "slice" was less than 15% of their earnings. This left a significant portion of their "pie" (take-home pay) remaining.
• Projected Scenario (2031): If this individual's salary increases in line with average earnings, they are projected to be "dragged" into the higher rate of tax by the end of the decade.
  • By 2031, their annual income is estimated to reach £62,000.
  • At this income level, they will be sacrificing one-fifth (20%) of their "beautiful pie" to HMRC, meaning a substantial portion of their increased earnings will be absorbed by higher income tax.

Logical Connections and Arguments

The core argument presented is that the freezing of income tax brackets, while seemingly a neutral policy, has a significant and increasing impact on the proportion of the population paying higher rates of tax. This is due to fiscal drag, where inflation erodes the real value of tax thresholds, effectively pulling more people into higher tax brackets as their nominal incomes rise to keep pace with the cost of living. The "pie" analogy effectively visualizes this phenomenon, showing how the slice taken by the taxman grows disproportionately larger for individuals as their earnings increase, especially when tax thresholds are not adjusted for inflation.

Conclusion

The extended freeze on income tax brackets, initiated by the Tories and continued by Rachel Reeves, is projected to significantly increase the number of higher-rate taxpayers. This policy, combined with nominal wage growth, will lead to a larger proportion of individuals' earnings being paid in income tax, thereby reducing their take-home pay relative to their gross earnings. The "pie" analogy clearly demonstrates how the tax burden on individuals escalates under these conditions.
