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 South Australia
South Australia has one of the highest thresholds at approximately $1.5 million, with a standard rate of 4.95%. SA uses a unique 'shade-in' mechanism: between the threshold and approximately $1.7 million, the effective rate ramps up gradually rather than jumping to 4.95% immediately. This smooths the impact for businesses near the threshold.
