All taxpayers with investment income have been sorted into deciles by the total value of their investment income
Source: Survey of Personal Income (SPI)
HMRC holds comprehensive income information for taxpayers but not for the rest of the UK population. Therefore the SPI is not a suitably representative data source for non-taxpayers and no attempt has been made to estimate the number of non-taxpayers or the amount of their income. Some interest and dividend income data may be incomplete and it is necessary to impute these amounts in a manner consistent with information from external survey data and the National Accounts.
