When it comes to doing business in Australia, understanding the taxation system is crucial for achieving both compliance and financial success. For small businesses, grasping the nuances of company tax can be particularly challenging but essential nonetheless. In this blog post, we at AE Wide Accountants aim to offer an overview of company tax in Australia, specifically in the context of small businesses.

What is Company Tax?

Company tax is levied on the earnings or profits of companies operating in Australia. This includes both Australian-based companies and international companies with Australian profits. It is a major source of revenue for the government and plays a crucial role in shaping the business landscape in the country.

Company Tax Rate

The company tax rate in Australia varies depending on the size and type of your business. Here are some general categories:

  • Small Business: Companies with an aggregated turnover of less than $50 million pay a reduced corporate tax rate, which is currently at 25% for the 2023-24 income year.
  • General Rate: Companies that do not qualify as small businesses are subject to the general company tax rate of 30%.

The table below shows the progressive changes to the company tax rate:

How Does Company Tax Affect Small Businesses?

Understanding company tax is essential for small businesses for several reasons:

Financial Planning

The amount of tax you pay has a direct impact on your bottom line. Understanding your tax obligations can help you with budgeting and financial planning.


Meeting your tax obligations on time is vital for avoiding fines and penalties. It’s important for small businesses to be diligent about compliance, given that they often have fewer resources to handle such financial setbacks.

Tax Benefits and Incentives

Australia offers several tax incentives targeted at small businesses, such as instant asset write-offs and simplified depreciation rules. Being informed about these can result in significant financial advantages.

Investment and Growth

For small businesses looking to expand or attract investors, a transparent and optimised tax strategy can make the company more appealing and financially stable.

Record-Keeping and Documentation

For both compliance and potential audits, maintaining accurate records is essential. You’ll need to keep records related to income, expenses, GST, payments to employees, and other business transactions. Proper documentation can also help you claim all the deductions you’re entitled to.


Understanding company tax is essential for any business operating in Australia, and the importance is magnified for small businesses that often operate with limited financial leeway. Company tax is not just a financial obligation but an integral aspect of business strategy and planning. Ensuring that you understand the basics can be the first step towards better financial health and long-term business success.
