Percentile points from 1 to 99 for total income before and after tax

This table shows the percentile points of the income distribution, estimated from the Survey of Personal Incomes each year.



The table only covers individuals who have some liability to Income Tax. The percentile points have been independently calculated on total income before tax and total income after tax.

As of 2023 to 2024, these statistics have been reclassified from National Statistics to National Accredited Statistics.

You can find more information about these statistics and collated tables for the latest and previous tax years on the Statistics about personal incomes page.

Supporting documentation on the methodology used to produce these statistics is available in the release for each tax year.

Note: comparisons over time may be affected by changes in methodology. Notably, there was a revision to the grossing factors in the 2018 to 2019 publication, which is discussed in the commentary and supporting documentation for that tax year. Further details, including a summary of significant methodological changes over time, data suitability and coverage, are included in the Background Quality Report.
