1. The Raise That Made You Poorer

You are 24. You earn £28,000. Your employer gives you a 4% pay rise — £1,120 gross. You feel good for about a week.

Then the numbers land.

Income tax takes 20%. National Insurance takes 8%. Your Plan 5 student loan takes 9%. That is a 37% marginal rate on your raise. Of the £1,120 your employer handed you, £414 goes straight to the government and the Student Loans Company. You keep £706.

CPI inflation is running at 3.0% as of February 2026. On a £28,000 salary, 3% inflation means you need £840 more per year just to stand still. Your net raise was £706.

Your 4% pay rise left you £134 a year worse off in real terms. That is £11 a month. You earned more. You took home less. The system pocketed the difference and nobody told you.

2. The Threshold Freeze: A Decade of Invisible Tax Rises

The personal allowance — the amount you can earn before paying income tax — has been frozen at £12,570 since April 2021. The higher rate threshold has been frozen at £50,270 over the same period. In the Autumn 2025 Budget, Rachel Reeves extended the freeze by three more years, to April 2031. A full decade.

This is called fiscal drag. Prices rise. Wages rise to keep pace. But the tax-free threshold stays pinned. Every year, a larger share of your income falls above the line and gets taxed. No Chancellor has to stand at the dispatch box and announce a tax increase. The inflation does it for them.

Since 2021, CPI has risen by 25.5%. If the personal allowance had tracked CPI — as it was supposed to before the freeze — it would now be £15,780, not £12,570. That is £3,210 of income that should be tax-free but is not. At the basic rate, that is £642 a year taken from every single worker in the country. Quietly. Automatically. Without a vote.

The Office for Budget Responsibility estimates that frozen personal tax thresholds will raise £29.3 billion a year by 2027-28 — equivalent to a 4p rise in the basic rate of income tax. The OBR also projects that 3.2 million people have been dragged into paying income tax who otherwise would not, and 2.1 million have been pushed into the higher rate who would have stayed in the basic band.

Nobody voted for any of this. No party put "stealth tax rise worth 4p in the pound" on a manifesto.

3. Why Under-30s Get Hit Hardest

Fiscal drag does not hit everyone equally. It hits young workers hardest, for four compounding reasons.

First: you entered the workforce after the freeze began. If you graduated in 2021 or later, you have never known a tax system where thresholds rose with inflation. The threshold was £12,570 on the day you started your first job. It will be £12,570 the day you turn 30. Every pay rise you receive between now and then will be partially or fully consumed by the gap between what you earn and where the tax line should be.

Second: your salary is in the exact bracket where fiscal drag bites hardest. The median salary for 22-29 year olds is approximately £32,000. That puts you squarely in the £25,000-35,000 range where the frozen personal allowance extracts the most from each additional pound.

Third: you carry student loans that previous generations did not. Plan 5 student loans — the terms for anyone starting university from September 2023 onwards — charge 9% on income above £25,000. That threshold is the lowest of any plan in recent history. Plan 2 graduates (2012-2023) start repaying at £27,295, which has itself been frozen since 2021. Another threshold that does not move. Another invisible deduction that grows as wages rise.

Fourth: the minimum wage is rising into the tax band. The National Living Wage rises to £12.71 per hour from April 2026. At just 20 hours per week for 50 weeks, that is £12,710 — breaching the personal allowance. A part-time worker on minimum wage is now an income taxpayer. In 2021, when the freeze began, the minimum wage was £8.91. You would have needed to work 28 hours a week to breach the threshold. The line has not moved. The wage has.

4. The Numbers: What You Actually Take Home

Here is what a young worker in England or Wales actually keeps in 2026, after income tax, National Insurance, and a Plan 5 student loan:

Gross Salary Income Tax NI (8%) Student Loan Total Deducted Take-Home Monthly
£22,000 £1,886 £754 £0 £2,640 £19,360 £1,613
£25,000 £2,486 £994 £0 £3,480 £21,520 £1,793
£28,000 £3,086 £1,234 £270 £4,590 £23,410 £1,951
£30,000 £3,486 £1,394 £450 £5,330 £24,670 £2,056
£33,000 £4,086 £1,634 £720 £6,440 £26,560 £2,213
£35,000 £4,486 £1,794 £900 £7,180 £27,820 £2,318
£40,000 £5,486 £2,194 £1,350 £9,030 £30,970 £2,581
£50,000 £7,486 £2,994 £2,250 £12,730 £37,270 £3,106

At £35,000 — a decent salary for someone a few years into their career — you lose one in every five pounds to deductions. At £50,000, it is one in four. And that is before rent, council tax, and every other cost of living that has outpaced your wage growth.

5. The £33,000 Test

Here is a comparison that puts the whole thing in relief.

In 2010, someone earned £33,000. A solid middle-income salary. They were £11,000 below the higher rate tax threshold of £43,875. Comfortable margin. Firmly in the basic rate band.

If that salary had kept pace with CPI inflation — just holding its real value, no real raise at all — it would now be £51,715. The higher rate threshold is £50,270. That person is now a higher rate taxpayer despite being no better off in real terms. Eleven thousand pounds of headroom has evaporated.

If the threshold had tracked inflation from 2010, it would be approximately £68,750. Instead, it is £50,270. The gap is £18,480 of income that was never supposed to be taxed at 40%.

In 1991, 3.5% of UK adults paid higher rate tax — 1.6 million people. By 2027-28, the IFS projects that figure will be 14% — 7.8 million people. One in four teachers. One in eight nurses. One in five electricians. The 40% rate used to mean you were well off. Now it means you are an experienced professional who has not changed jobs.

6. The Older Sibling Problem

If you are 25 and earning £30,000, the same job seven years ago paid approximately £23,100 in today's purchasing power. Your older sibling, doing that job in 2019, had an effective deduction rate 1.1 percentage points lower than yours. That sounds small. It is not. It means the government takes a bigger share of every pound you earn than it took from the person doing the same work before you — even though your real purchasing power is identical.

The difference compounds. Over a decade, fiscal drag on a modest salary accumulates into thousands of pounds. Over a career, it is six figures. A graduate starting at £28,000 today, receiving 3% annual pay rises, will pay an estimated £122,000 more in income tax over a 40-year career than they would if thresholds rose at the Bank of England's 2% inflation target. That is not a rounding error. That is a house deposit. That is a pension. That is the margin between getting ahead and treading water.

7. The System Is the Problem

Nobody designed this to target young workers specifically. But that is who it targets.

The freeze was introduced by Rishi Sunak in March 2021, extended by Jeremy Hunt in November 2022, continued by Rachel Reeves in October 2024, and extended again in October 2025. The freeze is expected to have raised £67 billion for the Exchequer by the end of the decade. Both parties have used it. Neither has had to announce a tax rise. The mechanism is politically frictionless.

It is also deeply regressive in its generational impact. Older workers who locked in mortgages at low rates, bought houses before the surge, and built their careers when thresholds rose with inflation have been partially insulated. Young workers have had none of those advantages and face all of the costs.

If you are under 30 and you feel like the system is not built for you, the data confirms it. You are not imagining it. You are not bad with money. You are not failing to budget properly. The structure of the tax system takes more from you than it took from your predecessors at the same real income, and it will continue doing so for the rest of the decade at minimum.

You are doing everything right. The system is not.
