Plain-English glossary
- Taxable wages
- Wages and wage-like payments that count for payroll tax under the relevant state or territory law.

Common questions
Is payroll tax the same as PAYG withholding?
No. PAYG withholding is a Commonwealth tax withholding system for worker pay. Payroll tax is a state or territory tax on taxable wages once the relevant threshold and rules are met.
Does payroll tax only count ordinary salary?
No. Payroll tax laws can treat a wider set of payments as wages, including some superannuation, allowances, fringe benefits, bonuses, commissions, contractor payments and employment agency arrangements.
Why do groups matter?
Related businesses can be grouped, which can affect threshold access and liability. That can matter for founders running multiple entities, franchise groups, family businesses and roll-up structures.
