Taxation can increase without the government ever officially raising tax rates. In the UK, this phenomenon is currently happening on a massive scale through a mechanism called fiscal drag. By freezing the personal allowance and higher-rate thresholds while wages rise due to inflation, the government is secretly collecting billions of pounds of extra revenue. In this guide, we explain what fiscal drag is, how it secretly affects your paycheck, and what you can do to protect your earnings in the 2026/27 tax year.
Understanding Fiscal Drag
Fiscal drag occurs when inflation-linked wage rises push taxpayers into higher tax bands because the thresholds for those bands remain frozen. In the UK, the core income tax thresholds have been frozen at their current levels since 2021:
- Personal Allowance: Frozen at **£12,570** (the income you can earn before paying any tax).
- Higher Rate Threshold: Frozen at **£50,270** (the income level where the tax rate jumps from 20% to 40%).
Under normal circumstances, these bands would rise in line with inflation (CPI). By keeping them frozen, inflation-fueled pay increases are taxed at higher rates, eroding your real purchasing power.
An Example of Fiscal Drag in Action
Imagine you earn £48,000 a year and receive a **5% pay rise** to offset inflation. Your new salary is **£50,400**:
- Although your salary increase only matches inflation, your purchasing power has not actually grown.
- However, because the higher rate threshold is frozen at £50,270, you are dragged over the limit.
- You must now pay **40% tax** on the £130 excess, rather than the 20% basic rate you paid previously. You pay more tax in real terms, making you worse off.

The Real Cost of the Frozen £12,570 Threshold
The standard tax-free Personal Allowance of £12,570 has been frozen since the 2021/22 tax year. According to calculations by leading tax institutes, if the threshold had risen in line with inflation (CPI) over the last five years, the allowance would be over **£15,500** for the 2026/27 tax year. By keeping it frozen, HMRC effectively taxes an extra £3,000 of every worker’s income, costing basic rate taxpayers an extra £600 per year, and higher rate taxpayers an extra £1,200 per year in real terms.
How Fiscal Drag Impacts Pensioners
Fiscal drag does not only affect working professionals. Because the UK State Pension increases annually under the “triple lock” mechanism to match inflation or wage growth, but the tax-free Personal Allowance remains frozen at £12,570, millions of pensioners are finding their retirement incomes dragged into the tax bracket. If your combined state and private pensions exceed £12,570, you will begin paying 20% income tax on the excess, even if your real-world standard of living has not increased at all.
What People Search For: FAQs on Fiscal Drag
1. What is fiscal drag in the UK?
Fiscal drag is a tax effect where inflation and rising wages push workers into paying more tax or entering higher tax brackets because the tax-free allowances and tax bands remain frozen.
2. When were the UK tax thresholds frozen?
The UK government froze the main income tax thresholds, including the £12,570 Personal Allowance and the £50,270 Higher Rate threshold, in April 2021, and they remain frozen for the 2026/27 tax year.
3. How does fiscal drag affect my net take-home pay?
Even if you get a pay rise that matches inflation, fiscal drag ensures that a larger proportion of your income is taxed at 20% or 40%, reducing your net take-home pay in real terms.
4. Is fiscal drag a hidden tax?
Yes. Economists call fiscal drag a “hidden tax” because it allows the government to increase overall tax revenue without having to announce politically unpopular rises in the headline tax rates.
5. How many people are affected by fiscal drag in the UK?
Millions of workers have been affected. Frozen thresholds have dragged millions of low earners into paying basic rate tax, and pushed millions of middle-income earners into the 40% Higher Rate band.
6. Will tax brackets change in 2026/27?
No. The core income tax brackets in England, Wales, and Northern Ireland remain frozen at £12,570 and £50,270 for the 2026/27 tax year.
7. How can I protect my income from fiscal drag?
You can mitigate fiscal drag by using salary sacrifice arrangements (e.g. paying more into your pension, cycle-to-work schemes) to lower your taxable salary and keep yourself below the frozen thresholds.
8. Does fiscal drag affect National Insurance?
Yes. The thresholds for National Insurance contributions have also been frozen alongside income tax bands, magnifying the tax drag effect for employees and self-employed workers.
9. Does fiscal drag impact pensioners?
Yes, significantly. Because the state pension increases with inflation (under the triple lock) but the £12,570 Personal Allowance is frozen, millions of pensioners are being dragged into paying tax on their pensions.
10. How does fiscal drag impact salary sacrifice schemes?
Fiscal drag makes salary sacrifice schemes far more appealing. As workers are pushed into higher tax brackets, the tax savings from sacrificing salary for benefits or pension contributions increase.
