Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what analysis her Department has carried out of the potential macro-economic effects (on investment, business growth, rental markets, and savings behaviour) of raising dividend, property and savings income tax rates by two percentage points as part of the 2025 Autumn Budget.

Economic 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, investment, or savings behaviour as a result of Budget 2025 tax changes.
