Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the policy document entitled Motability Scheme: reforming tax reliefs’ policy, published on 26 November, if she will publish the calculations used for the conclusion that the proposed changes are not expected to have any macroeconomic impacts.

The information set out in the macroeconomic impacts section of all Tax Information and Impact Notes (TIINs) corresponds to the assessments contained in the Office for Budget Responsibility’s (OBR) Economic and Fiscal Outlook. The OBR, as the Government's official forecaster, is responsible for judging the impact of policy decisions on its forecasts, including any underlying calculations.
