March 18, 2022         Fatima Raza

Calculating your company tax can be a confusing process due to the many factors that depend on it. Many elements play a part into how much tax your business has to pay such as business income, deductibles, company type etc. 

Who pays company tax? 

Companies that are Australian residents other than those that are considered as a corporate collective investment are subject to Australian income tax on their worldwide income. Non resident companies are also subject to Australian income tax but only on their Australian sourced income. 

The two tax rates

There are two tax rates and they depend on the annual turnover of the company:

30%

The full tax rate– All companies with an annual turnover exceeding $10 million pay the full business tax rate of 30%. Company types that fall under this rate include: 

  • Public trading trusts.
  • Regular company. 
  • Trustees of corporate unit trusts.
  • Corporate limited partnerships. 
  • Starte title bodies corporate.

27.5%

The lower tax rate– the lower tax rate is 27.5% and is eligible for:

  • Small or medium businesses if their annual turnover is less than $10 million. Keep in mind if you operate your business as a sole trader you won’t have to pay taxes on the first $18,200.
  • Base rate entities companies that have an aggravated turnover of $50 million from 2018-2019 or $25 million from 2017-2018. Furthermore 80% or less of their income is base rate entity passive income such as interest or rent. 

How to calculate company tax

Company tax is calculated from your assessable income minus deductions.  

              Taxable income= (Business income – Deductions)

Business/Assessable income

Most business income is an assessable income. However, your accounting method may alter which amounts will be included.

Your business assessable income should include:

  • All gross income (before tax): everyday business activities, foreign income, internet sales, income from sales (both cash and electronic). Just remember that gross income doesn’t include the goods and services tax (GST).
  • All other business income which isn’t a part of your everyday business activities such as: capital gains, cash prizes, changes in the trading stock value, cryptocurrencies etc. 

What NOT to include in your business’s assessable income

  • GST you’ve collected.
  • Borrowed money.
  • Betting and gambling wins.
  • Hobby earnings.
  • Inheritance or gifts.

Deductions
