TL;DR
Fiscal drag is what happens when tax thresholds stay frozen while wages rise. People pay more tax, and some move into higher bands, even though headline tax rates have not changed. UK Income Tax thresholds are frozen to 2031.

Key facts
- Fiscal drag = frozen thresholds plus rising incomes.
- Income Tax thresholds are frozen until the 2030/31 tax year.
- The Personal Allowance is £12,570; higher rate starts at £50,271.
- No rate change is needed for tax bills to rise under fiscal drag.
- Pension contributions can reduce taxable income and ease the effect.
What fiscal drag means
Income Tax is charged in bands. Each band has a threshold: a pound figure at which a higher rate starts to apply. When those thresholds are frozen but pay rises with inflation, a larger share of income falls into the taxed bands over time. The result is a higher tax bill without any change to the headline rates. Economists call this fiscal drag.
How it works in practice
The Personal Allowance is £12,570 and the higher rate threshold is £50,271. If these stay fixed while wages climb, someone who was comfortably a basic-rate taxpayer can, after a few years of pay rises, find part of their income taxed at the higher rate. They have not had a real-terms pay increase large enough to feel richer, but their tax bill has grown.
Why thresholds are frozen
Freezing thresholds raises revenue gradually without a visible rate increase. The current freeze on Income Tax thresholds runs to the 2030/31 tax year. Because the effect builds slowly, it is less noticeable than a rate rise, but over several years it can be significant.
Who is most affected
Anyone whose pay rises while thresholds are frozen is affected to some degree. The sharpest effects are felt by people whose income is near a threshold, since a modest pay rise can tip part of their income into the next band. People earning above £100,000 face an additional effect, as the Personal Allowance tapers away in that range.
What can ease the effect
Pension contributions reduce taxable income, which can keep income below a threshold. Salary sacrifice arrangements, ISA use and other allowances also play a part. The right approach depends on individual circumstances, including age, income mix and long-term plans.
Fiscal drag and the wider 2026 changes
Fiscal drag does not act alone. It runs alongside the dividend rate rise from April 2026, the savings rate rise, and the Personal Allowance allocation change from April 2027. Together these mean the tax position for many households is shifting even where headline Income Tax rates are steady.

Frequently asked questions
What is fiscal drag in simple terms?
It is when frozen tax thresholds, combined with rising incomes, increase tax bills and pull some people into higher bands without any change to tax rates.
How long are UK Income Tax thresholds frozen?
The freeze on Income Tax thresholds currently runs to the 2030/31 tax year.
Does fiscal drag mean tax rates went up?
No. The headline rates can stay the same. The extra tax comes from more income falling into the taxed bands as thresholds stay fixed and pay rises.
Can I reduce the effect of fiscal drag?
Pension contributions and other allowances can reduce taxable income, which may keep income below a threshold. The right step depends on individual circumstances.
Who is hit hardest?
People with income close to a threshold feel it most, since a small pay rise can move part of their income into the next band. Those earning above £100,000 also face Personal Allowance taper.
