Corporate tax rate reduction—large businesses

Budget Review 2016–17 Index

Les Nielson

Proposed changes

Over a 10 year period, starting from 1 July 2016, the company tax rate for all companies is to be reduced to 25 per cent. This will be achieved by progressively lifting the aggregated turnover threshold at which the small company tax rate of 27.5 per cent applies (see separate brief - Small company tax rate reduction). [1] The 27.5 per cent rate will then apply to all companies at which point in time, in 2024–25, the overall company tax rate will progressively reduce to 25 per cent. Table 1 sets out this time line:

Table 1: Time line for reduction in large company tax rate

Year Aggregated turnover threshold ($m) Rate (%)
2016–17 10 27.5
2017–18 25 27.5
2018–19 50 27.5
2019–20 100 27.5
2020–21 250 27.5
2021–22 500 27.5
2022–23 1,000 27.5
2023–24 1,000 27.5
2024–25 All companies regardless of turnover 27.0
2025–26 All companies regardless of turnover 26.0
2026–27 All companies regardless of turnover 25.0

Companies with an aggregated turnover above the relevant threshold in any one year would, until 2024–25, still be subject to a tax rate of 30 per cent.

The above table shows the combined corporate tax rate for central and sub-central governments, where the latter also imposes corporate tax. While is tempting to compare Australia’s headline corporate tax rate with those of other countries, regard should be had to the existence of the dividend imputation system, which only Australia and New Zealand have full implemented, which dramatically lowers the total tax collected from corporate profits.[12] The future tax rates are those that have been publically declared to date. They are unlikely to be the only such reductions.

Economic impact

The government claims that a more competitive company tax rate will generate economic activity encouraging investment, raising productivity, increasing Gross Domestic Product (GDP) and, over time, raising real wages and living standards.[13]

Any relationship between corporate tax rates and economic benefits is complex.[14] Further, the research is not conclusive and support can be found for both sides. [15] To the extent that there are benefits to lowering the corporate tax rate, there is a question about the time they will take to materialise and whether that will occur over the timeframe indicated by the Government. The Parliamentary Library can provide members and Senators with information about the available research.


Over the forward estimates period (to 2019–20) the proposed changes are to cost about $2.7 billion.[16] Over the full ten-year phase-in period to 2026–27, the Treasury Secretary has estimated that the changes in the main corporate tax rate, together with all the changes flowing from lifting the small business entity threshold, will cost the Commonwealth Budget $48.2 billion in cash terms.[17]

According to Section 328–120 of the Income Tax Assessment Act 1997 ‘annual turnover for an income year is the total ordinary income that the entity derives in the income year in the ordinary course of carrying on a business’.
