The budget vs your wallet: How the chancellor could raise billions

Key Concepts

• Productivity Flatlining: A significant issue in the UK economy where productivity growth has stagnated since 2008, leading to a 23% gap between potential and actual economic output.
• Fiscal Drag (Stealth Tax): A mechanism where inflation and wage increases push individuals into higher tax brackets or increase the proportion of their income subject to tax, even if tax rates remain unchanged. This occurs when tax thresholds and allowances are not adjusted in line with inflation.
• Personal Allowance: The amount of income an individual can earn before being subject to income tax.
• Austerity: Government policies aimed at reducing budget deficits through spending cuts and/or tax increases.
• Fiscal Drag vs. Tax Rate Increases: The transcript highlights that fiscal drag is becoming a primary method for governments to raise revenue, as direct increases to major tax rates (like the basic rate of income tax) are politically difficult.
• Complexity of Budgets: As governments avoid large, direct tax increases, budgets become more complex, incorporating numerous smaller measures to achieve revenue targets.

Economic and Fiscal Challenges

The UK economy is currently facing two major challenges that are overshadowing its fiscal situation.

1. Poor Economic Performance and Productivity Stagnation:

   • Productivity growth has flatlined since 2008.
   • This has resulted in a 23% gap between where the UK economy could be and where it is, making the nation "23% poorer."
   • This economic underperformance directly impacts public finances, as lower incomes lead to reduced tax revenues.
   • The Office for Budget Responsibility (OBR) is expected to provide a new assessment of future fiscal projections, which are not anticipated to be positive.

2. Unfulfilled Spending Commitments and Rising Welfare Costs:

   • Previous government promises, such as improving the welfare state and cutting certain allowances (e.g., winter fuel allowance), have not been fully realized.
   • Consequently, spending on welfare programs, including pensions and Universal Credit, is projected to increase significantly in the coming years.
   • The combination of lower tax revenues due to economic weakness and higher welfare spending creates a substantial hole in public finances.

Historical Context of Budgets

The transcript analyzes past UK budgets since 2010 to illustrate government fiscal strategies:

• George Osborne Era (Austerity): Budgets often involved significant spending cuts (represented by pink bars) to reduce deficits.
• Pre-Election Spending: In some instances, like before the 2015 election, there was a temporary increase in government spending.
• Post-COVID Response: The pandemic led to a large "splurge" of spending, followed by tax increases (e.g., National Insurance, Social Care Levy) to recoup funds.
• Mini-Budget and Jeremy Hunt: Following the mini-budget, Jeremy Hunt stepped in as Chancellor and implemented tax rises to address the fiscal situation.
• Spring Statement 2024 (Rachel Reeves): This budget involved significant extra spending, particularly on investments, alongside some tax levies.

The Upcoming Budget and Potential Tax Rises

The current outlook for the upcoming budget suggests it could be "miserable" and involve substantial tax raising measures.

• Estimated Tax Measures: It is anticipated that the budget will include around £35 billion in measures, predominantly tax rises.
• Scale of Squeeze: If this estimate is accurate, it would represent one of the largest fiscal "squeezes" since the George Osborne austerity period, though achieved through tax rises rather than spending cuts.
• Complexity: The budget is expected to be complex, with numerous smaller measures rather than large, overarching tax rate changes.

Fiscal Drag: The Primary Revenue Raiser

Fiscal drag is identified as the main mechanism for raising the projected £35 billion.

• Definition: Fiscal drag is a "stealth tax" where individuals pay more tax as their income rises, even if tax rates remain the same, because tax thresholds and allowances are not adjusted for inflation.
• Mechanism:
  • The personal allowance is the income level below which no income tax is paid.
  • Historically, the personal allowance increased, reducing the proportion of income taxed.
  • In recent years, the personal allowance has been frozen.
  • As incomes (median and top earners) have risen, a larger percentage of their income now falls above the frozen personal allowance, leading to increased tax contributions.
• Impact:
  • For the median household, the proportion of income taxed is projected to rise from approximately 52% in 2019 to 64% by the end of the current freeze period.
  • This increase in the taxed portion of income occurs without any change to the basic rate of income tax.
• Revenue Generation: Freezing allowances is estimated to generate around £8 billion.

Other Potential Tax Measures

To reach the £35 billion target, additional measures are likely:

• Mansion Tax: This is described as an additional council tax for properties in the top two council tax bands. While affecting a limited number of households, it could raise a few billion pounds.
• Comparison with Wealth Taxes: The UK does not have a wealth tax on financial assets, unlike countries like Norway, Spain, and Belgium. However, the UK already has high property taxes (council tax and business rates) compared to other developed nations. A mansion tax would further increase this burden.
• Miscellaneous Measures: Other potential revenue-raising measures include:
  • Changes to Capital Gains Tax.
  • A gambling duty.
  • Various other unspecified "itty bitty things" that the Chancellor has room to implement.

Increasing Complexity of Budgets

The transcript notes a trend towards more complex budgets over time:

• Historical Simplicity: Budgets in the 1970s and early 2000s often involved straightforward changes, such as increases to the basic rate of income tax or National Insurance.
• Avoidance of Major Tax Hikes: Governments have increasingly committed to not raising major tax rates, leading to a need for more numerous and smaller measures to achieve revenue targets.
• Consequences: This complexity can lead to budgets with many intricate details, potentially resulting in unintended consequences or measures that are politically unpopular or difficult to justify (e.g., the "omni shambles" budget).
• Future Outlook: The upcoming budget is likely to be complex, with a high number of measures, raising the possibility of "grenades" that could cause future problems.

Conclusion

The upcoming UK budget is poised to be a challenging one, driven by a combination of weak economic performance, rising welfare costs, and the government's need to raise significant revenue. Fiscal drag, achieved through the continued freeze of personal allowances, is expected to be the primary method of tax raising. This will be supplemented by a range of other measures, potentially including a mansion tax and various smaller adjustments, leading to a more complex and potentially contentious budget than in recent years. The transcript emphasizes that the scale of these measures and their potential impact are still subject to speculation, but the overall direction points towards a significant fiscal squeeze.
