Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the potential impact of the level of taxation as a result of the Autumn Budget 2025 on the economy.

HM Treasury does not publish forecasts of the economy. Forecasts, including assessments of the impact of policy decisions, are the responsibility of the independent Office for Budget Responsibility (OBR). The OBR publishes its forecast in the Economic and Fiscal Outlook (EFO). The OBR’s latest EFO can be found here: Economic and fiscal outlook – November 2025 - Office for Budget Responsibility. 

The OBR does not expect a material impact on economy-wide growth as a result of Budget 2025 tax changes.
