Compare Payroll Tax Across States
Payroll tax at this wage level
Between $5 million and $50 million in wages, payroll tax is a significant cost line — typically $250,000 to $2.5 million annually. Surcharges start applying in some states: QLD's higher rate kicks in at $6.5M, VIC's surcharge at $10M. At this level, payroll tax planning is a regular part of financial management, and multi-state employers need to actively optimise their interstate wage allocation and threshold utilisation.
State surcharges activate
VIC applies a 0.5% surcharge above $10M total Australian wages. QLD charges 4.95% (vs 4.75%) above $6.5M and adds a 0.25% mental health levy above $10M. These surcharges are based on total Australian wages, not just the wages in that state, so they can affect multi-state employers who have only a small presence in VIC or QLD.
Regional employee strategies (VIC)
Victoria's regional rate of 1.2125% (vs 4.85% standard) can save over $36,000 per $1M of regional wages. If your business can genuinely locate roles regionally — customer service, back office, warehousing — the payroll tax savings are substantial. Employees must work primarily (50%+) in regional VIC to qualify.
Typical businesses: Mid-to-large employers with 50-500 employees, national companies with multi-state presence, labour hire firms, and growing tech companies.
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.
