The tax rise no one announced

Two numbers have been doing Britain's taxing for five years, and they are about to meet. One is £12,570 — the personal allowance, the amount you can earn before income tax begins — which has not moved since 2021. The other is the state pension, which rises every April by law. The mechanism is called the triple lock: the pension goes up each year by whichever is highest of inflation, average earnings growth, or 2.5%, whatever the state of the public finances. Hold one number still while the other climbs, and they cross. Steve Webb, the former pensions minister who now tracks the system for the consultancy LCP, has put it plainly.

Two separate policies – triple lock uprating of the state pension and freezing of tax thresholds – will collide next year. — Steve Webb

The crossing is already on the schedule — the full new state pension is forecast to outgrow the £12,570 allowance by 2028 ^[1] — but the mechanism behind it has been running far longer. It is called fiscal drag: when tax thresholds are frozen, inflation and pay rises quietly pull people across them. You get a pay rise, the allowance stays where it is, and the Treasury keeps more of your money without a vote and without an announcement. No chancellor has announced a rise in the tax working people pay since Rishi Sunak first froze the thresholds in 2021. Rachel Reeves extended the freeze in her November 2025 budget, and John Healey kept it in the budget three days ago ^[2]. Reeves pushed it out to 2031; the Office for Budget Responsibility expects the freeze to pull 4.2 million more people into the income tax net by 2030 and to be raising about £23bn a year by 2030-31 ^[3]. The Centre for Policy Studies called it "fiscal drag in action, raising taxes for millions of workers through the back door." Reeves's answer was that she is asking everyone to make a contribution. Same fact, two framings — one quiet, the other, in her telling, merely fair. Either way, the revenue arrives without a rate rising. Once you know the trick, you see it everywhere. Nearly nine million pensioners are projected to pay income tax in the coming year — not because the tax was raised, but because their pension income no longer fits under the frozen £12,570 allowance ^[4]. The same arithmetic drives a second, smaller machine: the £35,000 means-test for the winter fuel payment is itself frozen, so the triple-lock rise alone was projected to push more than 100,000 pensioners over the line by April 2026, and up to half a million over four years ^[5]. Webb calls it a rollercoaster — the payment taken away in 2024, handed back in 2025, and lost again as the rising pension crosses the static cut-off. And HMRC claws the payment back from anyone above the line, through their tax code or a self-assessment return ^[6]. Higher up the income scale the freeze does stranger things: because the threshold where the 60% trap begins — the point where the personal allowance is withdrawn, so each extra pound is effectively taxed at 60p — has not moved, it now starts at £100,000 rather than the £155,000 it would have reached with inflation, and around 77,000 people over 66 sit inside it ^[7]. When the full pension crosses the allowance, the first bills land in April and May 2027 ^[1]. The fight over whether to switch any of it off is scheduled for April 2030 ^[8]. Then the machine hit the country, and the country hit back. The February 2026 poll that first put Reform UK ahead of the government blamed the lead on three things voters could name: council tax, energy bills, and the loss of winter fuel payments ^[9]. They were not abstractions — four in five of England's top-tier councils had just raised council tax by the legal maximum ^[10]. On 7 May the voters delivered it: Reform gained more than 1,400 seats, Labour lost more than 1,400 and about forty councils ^[11]. Starmer faced the cameras.

The results are tough, they are very tough, and there's no sugarcoating it. — Keir Starmer

He refused to resign that night ^[11], but by July he was gone and Burnham was prime minister on a promise to give the money back ^[12]. The strange part is what happened next, which is that almost nothing was switched off. Burnham's "reinstatement" of the winter fuel payment kept the £35,000 means-test and kept the HMRC clawback ^[12]. Healey's budget kept the threshold freeze ^[2]. And the party born of the backlash is meeting the same arithmetic in the councils it runs: as many as eight of the thirteen Reform-controlled councils have hinted at raising tax despite promises to cut it ^[13].

It would be easy to read that as hypocrisy, but it is closer to a confession about the arithmetic itself: no one who actually runs a council can afford to switch the squeeze off, because the squeeze is what pays for everything. By late October the backlash was already receding ^[14], and borrowing had already fallen to a three-year low in the year to March ^[15] — which made it easier, not harder, for the winners to keep the machine running. Now the wall. The IMF has told Britain it has reached the limit of what taxes can raise — the tax take is heading to a record 38.5% of national income — and that the next cuts must come from spending, naming the welfare bill and the triple lock ^[16]. The government's own Pensions Secretary has said reforming the triple lock is inevitable.

reforming the triple lock is the "right answer to a difficult question" — Pat McFadden

The decision is scheduled for April 2030, and both parties are now bidding on the same pot of money for different purposes. Labour would link the pension to earnings and bank a saving of around £22bn to fund a national care service ^[17]; the Conservatives want inflation-only rises from 2027 to fund defence ^[18]. The last fight was conducted in silence, item by item, by arithmetic. This one will be in the open, on the exact ground where that government fell. Steve Webb has an answer for anyone who says the country cannot afford the pension.

We need to rebalance. — Lord David Willetts
