Employer Costs and Employee Taxes in Australia
Australia's employer cost structure is deceptively simple on the surface (12% super, no social security) but state-based payroll taxes, modern award penalty rates and leave loading can push total costs well above the headline percentage.

Good to Know: Australia’s effective employer cost varies dramatically by state. Take an employee earning AUD 100,000 in Sydney: super AUD 12,000 (12%), NSW payroll tax ~AUD 5,450 (5.45% above threshold, prorated), workers’ comp ~AUD 1,500, leave loading ~AUD 1,350. Total employer cost: approximately AUD 120,300 or 1.20x salary. The same employee in Queensland triggers lower payroll tax (4.75%). In the ACT, it’s 6.85%. The super cap at AUD 62,500/quarter means employer super obligation flattens at AUD 7,500/quarter for very high earners, but few employees outside mining and finance hit that ceiling.
