Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate she has made of the number of additional people in (a) Witham constituency and (b) Essex who will be earning incomes that will be taxed by surpassing (i) the income tax threshold; and (ii) the higher rate of income tax threshold as a consequence of her policy to freeze those thresholds until 2030/31.

HMT/HMRC does not publish this information at constituency or local authority level.

By 2025-26 there were an estimated 5.66 million individual income taxpayers in the South East region which includes the Parliamentary Constituency of Witham and the Ceremonial County of Essex.

Regional breakdowns can be found in HMRC’s published Income Tax Liabilities Statistics in Collated Tables, Table 2.2.

This estimate is based on the 2022-23 Survey of Personal Incomes, projected to 2025-26 using economic assumption consistent with the Office for Budget Responsibility’s March 2025 Economic and Fiscal Outlook.
