Fiscal Drag UK Explained: Frozen Tax Allowances and Their Impact on Income Tax
Fiscal drag UK explained refers to a tax effect where individuals pay more tax over time due to rising incomes combined with frozen tax thresholds, rather than any change in tax rates themselves.

Over time, this leads to more taxpayers paying higher rates without any change in real purchasing power. For a full reference of where these frozen thresholds currently sit and how the bands are structured, see our guide on the current UK income tax bands and personal allowances.
How Frozen Tax Thresholds Affect Income Growth

- More income becomes subject to tax
- Individuals move into higher tax brackets sooner
- Real take-home pay may not increase proportionally to salary growth
This creates a hidden tax increase effect even when tax rates remain unchanged.
