In brief

On 26 November 2025, the Chancellor, Rachel Reeves MP, delivered the UK Budget saying that it makes the “fair and necessary choices” to deliver on the government’s promises. We highlight below some of the key business tax announcements made in the Autumn Budget, including changes to the UK capital allowances regime, reform of transfer pricing, permanent establishment and the diverted profits tax rules and new advance tax clearance services.

For details on other announcements made in the Budget, including the freezing of personal income tax thresholds to April 2031 and changes to salary sacrifice for pensions from April 2029, please see our Wealth Management alert here, Employee Benefit alert here and Pensions alert here.
