Payroll Tax: The State-Based Bill Growing Businesses Don’t See Coming
Payroll tax is one of the most commonly misunderstood obligations in Australian small business. Many owners assume it doesn’t apply to them. Some discover it applies when they weren’t expecting it. A few find out only after a state revenue office makes contact.
The confusion is understandable. Unlike GST or income tax, payroll tax is administered state by state, with different thresholds, different rates, and different rules in every jurisdiction. There’s no single ATO registration that covers it.
Here’s how it actually works, what the current thresholds are across the key states, and the three traps that catch growing businesses most often.
What Payroll Tax Actually Is
Payroll tax is a state and territory tax paid by employers on wages above a set threshold. It’s not deducted from employees. It’s a cost to the business on top of what it already pays in wages.
The rate is applied only to wages above the threshold, not to the full payroll. So, if your annual wages in NSW are $1.4 million and the threshold is $1.2 million, you pay 5.45 percent on the $200,000 excess, not on the full $1.4 million.
That distinction matters. It’s also where many business owners make their first calculation error.
The 2026 Thresholds for the Key States
Each state sets its own numbers, and they differ meaningfully.
In New South Wales, the annual threshold is $1.2 million at a rate of 5.45 percent. In Queensland, it’s $1.3 million at 4.75 percent, rising to 4.95 percent for larger employers. Victoria sits lower at $900,000, with a base rate of 4.85 percent, making it the earliest trigger point among the major states.
Western Australia’s threshold is $1 million at 5.5 percent. South Australia sits at $1.5 million. The ACT has the highest rate at 6.85 percent on a lower base.
These numbers can change with state budgets, so confirming directly with the relevant state revenue office before making decisions is always worthwhile.
Trap One: Total Australian Wages, Not Just Local Wages
This is the most common misunderstanding, and it catches businesses every year.
Registration is triggered in each state based on your total Australian wages, not just the wages you pay in that state. A business paying $600,000 in NSW and $700,000 in Victoria has $1.3 million in total Australian wages. That can trigger obligations in both states, even though neither state’s wages alone crossed the local threshold.
Many business owners calculate their position state by state and conclude they’re under the threshold. The rules don’t work that way.
Trap Two: Super Contributions Count Toward the Threshold
Most business owners know wages count toward payroll tax. Fewer know that employer superannuation contributions count too.
If you’re paying 12 percent super on top of salaries, that additional amount is included in your taxable wages for payroll tax purposes. For a business close to the threshold, this can be the difference between sitting below it and tripping over it without realizing.
As the super guaranteed rate sits at 12 percent from 1 July 2026, this is more relevant now than it’s ever been for businesses approaching the relevant thresholds.
Trap Three: The Grouping Rules
This one surprise business owners who operate through multiple related entities.
Most states have grouping provisions that aggregate wages across related businesses when determining payroll tax liability. If you own two separate companies under a common structure, their combined wages are generally treated as one employer’s wages for threshold purposes.
That means splitting a payroll across multiple entities doesn’t create multiple thresholds. It creates one group threshold, shared between all of them. Businesses that set up separate entities expecting separate thresholds often discover this the hard way.
What’s Included in Taxable Wages
Payroll tax is broader than most business owners expect when they first encounter it.
Gross salaries and wages are included, as expected. Superannuation contributions are included. So are allowances, bonuses, commissions, and fringe benefits in many circumstances. Contractor payments can also be included in some situations, depending on the nature of the arrangement and the state’s specific rules.
The practical implication is that a business whose salary bill alone sits comfortably below the threshold may still cross it once all relevant payments are added.
When to Register, and What Happens If You Don’t
Registration is required when your total Australian wages exceed the monthly threshold in any calendar month, which works out to roughly $100,000 per month in NSW.
Failing to register on time doesn’t remove the liability. It adds to it. Penalties for late registration can reach significant amounts, plus interest on unpaid tax calculated from when the obligation first arose. Proactively registering when you approach the threshold is always preferable to being contacted by a state revenue office after the fact.
Frequently Asked Questions
Is there a small business exemption for payroll tax? No. There’s no specific exemption for small businesses. The threshold itself is the only protection, and it’s based on total Australian wages, not the size of the business.
Do I need to register in every state where I have employees? You register in the state where your employees perform their work. If you have staff in multiple states, you may have obligations in each one.
My wages are below the threshold this year. Should I still monitor it? Yes. As wages grow, many businesses cross the threshold without realizing it, especially once super contributions and allowances are factored in.
What if I’ve been over the threshold for a while without registering? Contact the relevant state revenue office as soon as possible. Early engagement is consistently treated better than waiting to be discovered.
