8 min If you’re running a business in Australia, chances are you’ve asked yourself: What is payroll tax, and how does it affect me as an employer? Payroll tax is one of those employer obligations that can’t be ignored. Even small missteps, like overlooking thresholds or filing late, can result in penalties that quickly eat into your business profits.
Payroll tax rules vary between states and territories, making it sometimes seem like a lot to comply with. This manual deconstructs the basics of payroll tax in Australia for 2025 so that you can spend less time confused and more time keeping your business running efficiently.
What Is Payroll Tax?
Payroll tax is a state and territory tax on wages, paid by employers. Payroll tax is different from income tax, which is levied by the federal government. The state and territory government collects the money, and it goes into supporting public health, education, and infrastructure.
Payroll tax applies once your business’s total wages exceed a certain threshold, and the amount payable is calculated as a percentage of your wages. Each state sets its own tax rates and thresholds, which means employers with staff across multiple states need to track obligations carefully.
In most cases, payroll tax is paid monthly, with an annual reconciliation to confirm the correct amount has been lodged.
Payroll Tax Rate and Thresholds in 2025
What is payroll tax? One of the first things to know about payroll tax is that there isn’t one, standard rate or threshold across Australia. Each state and territory is different.
For instance, in New South Wales, payroll tax is charged at 5.45% after yearly wages have been more than $1.2 million. Victoria charges metropolitan employers a fixed rate of 4.85%, but regional companies enjoy much lower coverage of 1.21%, provided they primarily have employees based in regional regions.
Queensland charges the basic rate of 4.75% if total wages are below $6.5 million, and 4.95% if they are more than that amount, with the cut-off at $1.3 million. Western Australia has a uniform 5.5% once wages exceed $1 million, and South Australia has a progressive system that starts at 0% and rises incrementally to 4.95% for larger wage bills.
In contrast, Tasmania imposes 4% payroll tax on employers with salaries up to $5 million and 6.1% for employers over that, with a minimum threshold of $1.25 million. One of the higher rates belongs to the ACT at 6.85% over a $2 million threshold, while the Northern Territory charges 5.5% after wages reach $1.5 million.
These distinctions are evident as to why companies can’t use a “one-size-fits-all” strategy. When you have employees in more than one state, you must register in each state and follow the applicable rules.
What is Considered Wages for Payroll Tax?
Payroll tax is not just limited to base wages. The definition of “wages” is more inclusive than many company owners assume, and this is often where compliance errors happen.
For pay-roll tax purposes, wages generally encompass:
- Gross salaries and wages paid to employees
- Employer contributions to superannuation
- Bonuses, commissions, and allowances
- Fringe benefits (defined under Fringe Benefits Tax)
- Some contractor payments, based on the criteria of the state
That final category, contractor payments, catches employers out. Contractor arrangements in some states can still be treated as taxable for pay-roll tax purposes if the contractor is essentially providing employee-like services.
Why Payroll Tax Compliance Matters
You might ask why payroll tax should be given such close scrutiny when your company is already meeting PAYG withholding and superannuation requirements. The answer is straightforward: non-compliance with payroll tax is expensive.
State revenue offices have also been more vigilant in detecting mistakes and underpayments. In most instances, they collaborate with the Australian Taxation Office (ATO) to cross-reference records, so even a minor miscalculation may initiate an audit. The penalties may include back-payments of tax, interest, and heavy penalties.
Aside from the monetary effect, not complying with payroll tax can hurt your reputation. Companies that compete for government contracts or grants tend to be required to prove complete compliance with state taxation. A payroll tax problem can cost you more than money, it may cost you opportunities for expansion that is why financial management is important too.
Best Practices for Managing Payroll Tax in 2025
Payroll tax does not have to be complicated. With the proper strategy, you can remain compliant and efficient in your business. Below are some best practices for 2025:
Use Automation Wisely:
Invest in payroll software like Xero Payroll, MYOB, or KeyPay to make automatic calculations, reporting, and lodgment. This eliminates human error and keeps you on track.
Stay Updated on State Rules:
Because each state has its own thresholds and rates, make it a habit to check your state revenue office’s website at the start of every financial year.
Keep Accurate Records:
Align payroll data with superannuation and contractor records to avoid discrepancies. Cloud-based solutions like Employment Hero or BambooHR can integrate multiple HR functions into one system and provide the ultimate HR support.
Train Your Payroll Team:
Technology is strong, but only if individuals understand how to deploy it. Ensure that your payroll staff receives training on the software and the particular tax requirements that pertain to your company for easier Workforce Management.
Review Regularly:
Don’t wait until annual reconciliation to verify your figures. Review payroll reports on a monthly or quarterly basis to identify mistakes early.
Streamlined payroll is not merely about compliance. It can also enhance employee experience through accuracy in pay and superannuation, enhancing trust and retention.
