A pay rise should feel like progress. A pension increase should feel like protection. In both cases, the aim is the same: to help income keep pace with life. For many people in the UK, the reality is more complicated.
What is fiscal drag — and why does it matter now?
Key tax thresholds are frozen until 5 April 2031. The personal allowance remains at £12,570, the higher-rate threshold remains fixed, and the Inheritance Tax nil-rate band and residence nil-rate band are locked in place through the 2030/31 tax year.
When income rises but thresholds do not, more of what you earn is pulled into tax — or into a higher rate of it. You may be better paid without being meaningfully better off. This is fiscal drag, and it is why the effect is often called a stealth tax: tax rates do not need to change for the amount of tax you pay to increase.
The 6 April reality check
The new tax year begins on 6 April, but the personal allowance stays frozen at £12,570. The higher-rate threshold remains at £50,270 across England, Wales and Northern Ireland.
As wages rise, more people are being drawn into the 40% band — not because of a fresh policy change, but because their income has moved while the boundary has not. Those earning above £100,000 face a sharper effect still, as the personal allowance tapers away. This can create an effective marginal tax rate of 60% on part of their income.
The same dynamic applies to estates. Frozen Inheritance Tax thresholds, combined with rising property values and investment growth, are quietly pulling more families into scope.
Fiscal drag does not stop at retirement
This is the part of the story that is often missed.
Many retirees receive income that grows each year. The State Pension rose by 4.8% from 6 April 2026 under the triple lock. Many Defined Benefit pensions also increase annually, often with some link to inflation. That is welcome, because rising income helps protect spending power.
But with the personal allowance frozen, those same increases can push more retirement income into tax. Someone who once paid little or nothing in retirement may gradually find that more of their State Pension, workplace pension or private pension income becomes taxable. The effect may be slower in retirement, but it is no less real.
What can be done about it?
You cannot move the thresholds. But you can often control how income, pensions and investments are structured around them.
For working clients, pension salary sacrifice is worth examining where it is available. Exchanging part of salary for an employer pension contribution reduces taxable income. This can help manage exposure to higher-rate tax, preserve the personal allowance for those approaching £100,000, and build retirement provision at the same time.
For both working and retired clients, ISAs continue to earn their place. Growth and income within an ISA are free from Income Tax and Capital Gains Tax, withdrawals are tax-free, and using the allowance early in the tax year gives investments more time to compound in a sheltered environment.
For those in retirement, the focus often shifts to withdrawal sequencing: deciding when to draw from pensions, ISAs, cash savings or other investments. The goal is not to avoid tax at any cost, but to draw income in a considered order and avoid unnecessary leakage.
Planning before it happens to you
Fiscal drag is easy to miss because nothing dramatic announces itself. Rates stay the same. Thresholds stay the same. But income, pension values and assets keep moving — and the gap quietly widens.
A pay rise is still good news. So is a pension increase. But in the frozen years, both need to be seen in context.
The practical step is to review income, contributions, ISA use and withdrawal strategy early in the tax year — before tax becomes something that simply happens, rather than something that has been planned for.
