Compare Payroll Tax Across States
Payroll tax at this wage level
At wages under $1.5 million, you fall below the threshold in many states — ACT ($2M), SA ($1.5M), QLD ($1.3M), TAS ($1.25M), and NSW ($1.2M) all have thresholds in this range. You may only be liable in VIC ($900k) and WA ($1M). For a single-state employer at this level, payroll tax may be zero or minimal. The biggest risk is inadvertently crossing the threshold through hiring or wage increases mid-year.
Registration threshold
You must register for payroll tax once your total Australian wages exceed (or are expected to exceed) the state threshold within a financial year. Registration is required within 7 days. Failing to register and pay can result in penalties and interest backdated to when the liability first arose.
Watch for threshold crossing mid-year
If you hire staff or increase wages partway through the year, you may cross the threshold for the full year — not just from the date of crossing. Payroll tax is calculated on annual wages, so a December hire can mean payroll tax applies from the preceding July.
Typical businesses: Small businesses with 5-15 employees, sole traders with a few staff, early-stage startups, and small professional practices.
Payroll Tax in Western Australia
Western Australia has a threshold of approximately $1 million and a rate of 5.5%. WA is unique in using a diminishing threshold — the threshold reduces as wages increase above the upper limit, eventually reaching zero for very large employers. This creates a smooth ramp-up in effective rate rather than the sharp jump seen in other states.
