Chancellor Rachel Reeves froze income tax thresholds, announced new levies on wealth and investment and scrapped the two-child benefit cap in a statement to parliament known as UK Budget 2025 — which has handed Britain another very large peacetime tax rise. She said the package was necessary to prop up public finances and meet welfare pledges, even as investors nudged gilt yields down and London stocks up in a gingerly, optimistic response to Britons desperate for Christmas gifts.

How Budget 2025 is changing the tax and welfare panorama in the UK
The Office for Budget Responsibility (OBR) has estimated that Reeves’s measures will raise around 26 billion pounds a year by the end of the decade, mainly via a three-year extension of the income tax threshold freeze from 2028, increased taxes on dividends, savings and property income and a new high-value council tax surcharge on homes valued at more than £2m – according to an RNZ detailed report based on Reuters. That takes the total tax burden to 38.3 per cent of G.D.P. by 2030–31, a peacetime high.
UK Budget 2025 raises taxes from several quarters. The defrosting of the long-frozen threshold, first extended under the last Conservative government and now due to run until at least April 2031, threatens to hoover up millions more workers into paying income tax or higher rates. A new “mansion tax” style surcharge on properties worth more than 2 million pounds, a mileage-based charge for electric and plug-in hybrid cars from 2028, higher duties on gambling and alcohol, plus a 2-percentage-point increase in dividend tax rates, underscore Reeves’s assertion that those with the “broadest shoulders” should pay more while also ensnaring many upper-middle-income households.
One of the most symbolic steps in the UK Budget 2025 will be the decision to end, from April next year, the two-child limit on welfare payments — a flagship Conservative policy from 2017 that was widely seen as targeting large families. Scrapping the cap would cost a little more than 3 billion pounds a year by 2029–30, would benefit about 560,000 low-income families, and independent analysts say it could lift hundreds of thousands of children out of poverty, even though polls continued to find majority public support for the cap.
Markets like UK Budget 2025 — for now
Financial markets signalled relief that the chancellor had delivered a tax-heavy but broadly orthodox package. Long-dated gilt yields dropped by roughly 11 basis points, the largest one-day fall since April, after the OBR said that Reeves now has nearly £22bn of headroom relative to her main fiscal rule; the FTSE 100 ended around 0.9 per cent higher, and sterling rose about 0.5 per cent against the dollar according to Reuters market coverage. Investors and major asset managers stepped up to buy UK government bonds following the statement, believing the risk of a repeat of the London 2022 event had receded.
Think tanks were swift to highlight that the ostensible fiscal toughness of the UK Budget 2025 is massively back-loaded. In a first assessment, the Institute for Fiscal Studies said taxes will rise from 36.3 percent of national income this year to 38.3 percent by 2030–31 — the highest in at least half a century — but much of that extra revenue comes only in the final years of the parliament while spending rises sooner, giving it “a spend now, pay later” profile that leaves future chancellors with tough choices.
The trajectory had been years in the making. The OBR’s March 2025 Economic and fiscal outlook already showed that earlier National Insurance rises, together with some fiscal drag, will drive the tax share of GDP to successive records over the forecast period. In its spring statement verdict, the Institute for Government said that Reeves had a mere sliver of headroom and was papering over deeper pressures in public services, suggesting that tax or spending decisions would become increasingly difficult later in the parliament.
Politically, the UK Budget 2025 provides Labour with the cover of finally being seen to have finally scraped a welfare policy many of its MPs found morally beyond the pale, while still reassuring markets that it will adhere to debt and deficit rules. But it welds Britain to a historically very high tax burden and depends on future governments making and sticking to tight spending settlements and elaborately designed new taxes that could prove hard to sustain. With a general election required by 2029, Reeves has decided to bank credibility with investors now and defer much of the political pain for another day.
