How Frozen Personal Allowances Increase Your Tax Bill

Individuals whose income is rising due to inflation or pay increases and who may be affected by frozen tax thresholds. What fiscal drag means, how frozen personal allowances affect taxpayers, and why inflation and wage growth can increase tax liabilities. When personal allowances and tax thresholds remain fixed while income increases, more income can become taxable or move into higher tax bands.

What Is Fiscal Drag?

Fiscal drag occurs when tax thresholds are frozen and incomes increase. As earnings rise but allowances remain unchanged, a greater proportion of income may be subject to tax.

Frozen Personal Allowances

Personal allowances and tax thresholds have been frozen. This means that, despite rising wages or inflation, the amount of income that can be earned before tax applies does not increase.

Impact of Inflation and Wage Growth

Inflation and wage growth can result in higher nominal incomes. However, if tax thresholds remain unchanged, individuals may pay more tax even if their real purchasing power has not significantly increased. Projections from the Office for Budget Responsibility (OBR) indicate that more individuals may be drawn into higher tax bands over time as a result.

Real-World Impact

  • An employee receiving a pay rise in line with inflation may move into a higher tax band.
  • An individual previously below a tax threshold may find more of their income taxable.
  • Over time, frozen allowances can increase overall tax exposure without changes in lifestyle or spending power.

Key Considerations

  • Frozen allowances can increase tax liabilities gradually.
  • Rising income does not necessarily equate to increased real income after tax.
  • Fiscal drag can affect a growing number of taxpayers over time.
You may wish to review your income position in light of frozen personal allowances and projected wage growth.
