​Could you provide the top 20th (80th percentile) of income before tax in the UK for each age group?

We said

Unfortunately, we do not hold information on the 80th percentile of income before taxes in the UK for each age group.

Within our effects of taxes and benefits on household income, disposable income estimate: 2019 data tables, we produce information on overall distribution of income (Table 3), and average income by different age groups (Table 7).

It is possible that we could create bespoke information on the 80th percentile of income before taxes for some age bands using existing data. If you'd like to request this bespoke dataset, please get in touch at hie@ons.gov.uk. Please be aware that this request would fall outside of the Freedom of Information reegime and would be subject to legal frameworks, disclosure controls, resources and agreement of costs, in line to our charging policy.
