Australian Corporate Taxation

Company Taxation in Australia : A Short Summary

We regularly receive inquiries about establishing companies in Australia and particularly their taxation. In the paragraphs below we summarise some of the major issues, although there is a reasonable degree of complexity and we strongly recommend specific advice from an experienced tax and corporate advisor before proceeding to establish a company or other entity, such as a trust; access to professional advice is available through the Inquiry form at the bottom of this page.

The main types of business entities

  • Company
  • Branch of overseas company
  • Partnership/ Joint venture
  • Trust
  • Corporate limited partnership

The most common operating entity is an Australian incorporated company.

Business Taxation

  • Company tax rate is 30%, except for "small businesses" (aggregate turnover below $50 million), which are subject to a reduced tax rate of 25% for 2021-22 and future years
  • No branch profits tax
  • Assessable income includes most business revenue including gross income from sales and services, dividends, interest, royalties and capital gains.
  • Allowable deductions include most business expenses including depreciation, royalties, interest, management fees, and payroll taxes. Entertainment costs are not deductible.
  • Prior year losses can be deducted against current year profits and capital gains provided the company passes a Same Owner test or Same Business test. Capital losses can only offset capital gains. Current year losses can be carried back to offset prior year profits in limited circumstances.
  • Tax incentives are available for certain R&D activities carried on by Australian companies.
  • Deductions are not allowed for allowances such as holiday pay, sick leave and long service leave until actually paid to the employee
  • Strict transfer pricing rules require international dealings to be on an arm’s length basis which could impact interest, management fees, royalties paid to related parties overseas.
  • Interest on borrowings is not deductible where total debt to equity is greater than 1.5:1.Non-deductible interest is still subject to withholding tax.
  • Dividends from the foreign subsidiaries of Australian companies are generally exempt from tax, but no credit is available for foreign dividend withholding taxes paid

Withholding Taxes


  • Dividends from previously taxed profits (franked dividends) are not subject to withholding tax.
  • Unfranked dividends are subject to 30% withholding tax, which may be reduced under applicable double tax treaties. Australia’s tax treaties reduce dividend withholding tax to between 0% - 15% depending upon the country of residence of the shareholder


  • Interest withholding tax is 10% and is generally not reduced by treaties.


  • Royalty withholding tax is 30%, generally reduced to 10% or less by treaties.

Wage Tax/ Social Security Contributions

  • Employers are required to contribute 11% of each employee’s ordinary time earnings (up to a quarterly salary cap) to an Australian superannuation fund. The rate is scheduled to increase over time to 12%
  • Employers must withhold tax from each employee’s regular salary and wages and forward them to the Australian Taxation Office
  • Fringe Benefits Tax (at 47%) is paid on most non-cash benefits paid to employees. The FBT is tax deductible.
  • There is no capital duty on value of outstanding shares

Goods and Services Tax (GST)

  • GST at 10% is payable on most supplies of goods and services in Australia. GST is not payable on certain financial transactions, food, health and educational services.

State Taxes

  • The Australian states and territories impose a range of taxes and charges on business including payroll taxes (generally around 5% of total payroll above a threshold amount), land taxes, stamp duties on certain transfers and documents


  • Income tax returns are lodged annually based on a 30 June year end. Different year ends can be granted by the Australian Taxation Office.
  • Income tax is paid based on quarterly instalments with any balance paid 5 months after year end
  • Separate returns need to be prepared for GST, FBT and the various state taxes
