To ask the Chancellor of the Exchequer, with reference to paragraph 4.25 of the Office for Budget Responsibility's Economic and Fiscal Outlook, published in March 2019, if he will publish the most recent data by (a) percentile and (b) decile relating to mean total pay.

HM Revenue and Customs (HMRC) publishes information on income and tax by percentile groupings in Table 2.4 of their Income Tax statistics and distributions publication, available here: https://www.gov.uk/government/statistics/shares-of-total-income-before-and-after-tax-and-income-tax-for-percentile-groups.

HMRC also releases a publication containing quarterly statistics about pay earnings derived from Real Time Information. These statistics are relatively new and their content is under development.
