Demystifying Payroll Tax: A Guide for Businesses in Perth

Understanding the Key Components, Tax Allocations and Legal Requirements

Payroll is a crucial aspect of running a business, and understanding the intricacies of payroll tax is essential for compliance and financial stability. In this guide, we will demystify the complexities of payroll tax, providing businesses in Perth with valuable insights into calculating wages, taxes, deductions, and legal requirements.

Key Components of Payroll

Payroll encompasses various tasks, including salary and tax calculations, and compliance with legal regulations. Understanding these components is vital for accurate and efficient payroll management.

  • Salary Calculation: Accurately calculating wages or salary based on employment terms, including overtime, bonuses, and incentives.
  • Taxes: Calculating PAYG Withholding, Superannuation and other applicable deductions as per employment contracts and applicable laws. This also includes accounting for employee packaging benefits
  • Compliance and Reporting: Staying up to date with tax laws, minimum wage regulations, and labour laws to ensure legal compliance.


Payroll tax in Western Australia is a state and territory tax that businesses must pay to their local revenue office if they exceed the tax threshold in that state or territory. As a self-reported status, the onus is on you as the business owner to report your payroll amount to the revenue office.

You’ll need to check each state’s limits if you have employees in multiple states, as this is a cumulative figure. For example, in the financial year 2018 to 2019, QLD and NSW had a 31-day threshold of $91,666 and $72,192, respectively. If you employ staff in QLD and NSW and your total Australia-wide wage bill for those 31 days is:

$95,000 – you need to register for payroll tax in both states

$75,000 – you only need to register in NSW

You do not have to pay if your total Australian wage bill is under the maximum threshold for your state or territory.


Demystifying Payroll Tax Calculations

Navigating payroll tax calculations can be challenging. It involves understanding tax rates, employee tax codes, and the process of deducting and remitting taxes to the appropriate authorities.

In the context of Perth, businesses need to be aware of the specific tax regulations and rates applicable to their location. This includes state payroll taxes in addition to federal requirements.


What is the payroll rate in Western Australia?

Compliance with legal and regulatory requirements is fundamental to payroll tax management. Businesses must adhere to laws related to employee taxation, reporting, and remittance of taxes to the authorities.

In Perth, businesses are subject to Australian taxation laws, and staying informed about the latest updates and changes in tax regulations is imperative. Your payroll tax is calculated based on the total wages you pay each month. For businesses in WA, this threshold is $83,333 per month or $1 million annually.
