Chancellor Rachel Reeves is set to deliver her inaugural full autumn budget on 26 November, as announced by the Treasury, amidst growing speculation about possible tax increases to address a public finance deficit of up to £40 billion. This announcement provides Reeves with ten weeks to prepare a crucial package of tax and spending measures, at a time when borrowing costs, persistent inflation, and a weak growth outlook are impacting the economy. The Treasury has confirmed that the Office for Budget Responsibility (OBR) has been tasked with producing updated forecasts for the economy and public finances.
Reeves and Prime Minister Sir Keir Starmer have consistently pledged not to raise taxes on “working people” by increasing income tax, national insurance, or VAT. However, Reeves is exploring options to generate more revenue from wealthier taxpayers, including potential changes to capital gains tax, inheritance tax, and property levies. Some left-wing Labour MPs and campaigners have urged her to introduce a wealth tax, though Treasury insiders suggest Reeves has privately dismissed this idea.
Business leaders have cautioned that significant tax increases in November could exacerbate challenges for households and companies, potentially hindering growth. The timing of the budget allows Reeves to use the party’s autumn conference in Liverpool, starting in late September, to shape the political narrative. Treasury officials are also hopeful that updated International Monetary Fund forecasts, due at its annual meeting in mid-October, could provide more favourable news for the chancellor.
Nonetheless, external risks remain significant. The government is concerned about rising global inflationary pressures, Donald Trump’s escalating trade war, and volatility in financial markets potentially worsening Britain’s outlook ahead of budget day. The announcement on 26 November highlights the delicate balance Reeves must maintain. Having already introduced £40 billion in tax rises in last year’s budget to stabilise public finances, she now needs to persuade markets and voters that Labour can balance fiscal responsibility with its commitment to driving growth.
For businesses and households alike, the November budget is poised to be one of the most significant in recent years, setting the tone for Labour’s economic credibility after a challenging first year in government.
