Why a pay rise can feel like a pay cut — and the income that didn't get frozen

Strip the week's loudest worry down and it isn't really about robots. It's a question millions of people are asking in kitchens: I earn more than I used to — so why doesn't it feel like it? The machines are one answer, and this paper spends most of its time on them. But there's a second answer, closer to home and entirely man-made, and it's worth seeing plainly.

For most of a working life, the tax you pay is governed by thresholds — the point where each rate kicks in. Since 2021 those thresholds have been frozen in cash terms, and in the Autumn 2025 Budget the freeze was extended to April 2031. Wages rise; the thresholds don't. So each pay rise drags a little more of your income into a higher band, even when you're no better off in real terms. The Office for Budget Responsibility reckons the freeze will raise an extra £55bn a year by the end of the decade — a tax rise nobody ever had to announce.

Then there's the cliff almost nobody plans for. Cross £100,000 and your tax-free personal allowance is withdrawn, £1 for every £2, until it's gone at £125,140. In that band, every extra pound is taxed at an effective 60% — 62% once National Insurance is counted. It appears on no rate card. It just sits there, waiting.

Here's the tell, and it's in what didn't move. While the thresholds on earned income were frozen, the state pension kept its "triple lock" — rising each year by the highest of earnings, inflation or 2.5%. Read the two policies together and the machinery says something quiet but real: the system now shields the income you get for not working from inflation, while letting inflation quietly tax the income you get for working. That's the "does work pay" feeling, and it has a mechanism.

None of this tells you what to do with a single pound. But if a pay rise or a bonus is on the horizon, it's worth understanding how the frozen bands and the £100,000 edge actually work — because the number on the offer letter and the number that reaches your account have quietly drifted further apart.
