Notes about tax statistics

  • Tax statistics include only data collected by Inland Revenue.
  • Statistics cover the period from 2001 onwards. For the years before 2006 please go to the second worksheet in the Excel workbook.
  • Some numbers in the tables are rounded, which means the totals are not always consistent with the sums across the corresponding categories.
  • We provide revenue and debt statistics for each fiscal year ending 30 June. All other data is at or for the tax year ending, 31 March.
  • Tax statistics are dynamic and are continuously updated due to return filing processes. The data is correct as of the date of extraction.
