Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate she has made of the total income tax receipts from income taxpayers in (a) Witham constituency and (b) Essex in (i) the current financial year and (ii) each of the next five financial years; and the additional income as a result of her policy to extend the freeze in income tax thresholds to 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.
