The tax for Australian companies is a flat 30% on all income, unless it is a small business entity with a business turnover under $50 million and qualifies for the lower company tax rate of 26%.
The company doesn’t receive a discount for any capital gains. In this example the company only conducts investment activities and does not run a business, so tax still applies at 30% (or it would reduce to 26% if it was a small business entity).
The taxable income for the company is shown in the top table.
The tax payable by the company in 2020/21 is $21,300, as shown in the second table (or $17,660 for small business entities).
Note: if this money was subsequently paid as a dividend by the company to shareholders, there may be further tax to pay by the shareholders if they have a marginal tax rate higher than the company tax rate.
