Total tax revenue, share of GDP
What the numbers are telling us
Total tax revenue, share of GDP was 29.9% in 2023, up 0.56 pts on the previous reading (29.3%).
It is above its 10-year average of 28.4%.
Across 32 OECD countries (2023), Australia ranks 23rd highest of 32 on total tax revenue, share of GDP, below the median of 34.9%.
Why it matters
How much of the economy government collects in tax, including social security contributions.
What it should be
There is no official target for this measure, so it is judged against its own 10-year average of 28.4%: a higher or lower reading is not in itself better or worse. The OECD median is 34.9%.
Every figure on this page is calculated from the stored official series (OECD, Revenue Statistics: comparative tax revenues); the summary is written from the numbers, not edited by hand.
