Multi-state payroll tax calculator
Calculate payroll tax across all eight states and territories, with the medical exemptions and contractor rules already in the engine. Change the financial year at the top to work with historical rates.
Payroll Tax Calculator
Enter annual or monthly taxable wages for each jurisdiction where your group operates. The engine apportions thresholds, evaluates surcharges, and produces an itemised liability breakdown instantly.
Toggle off if this entity is a non-DGE group member (no threshold).
Enter wages for at least one state to see the breakdown
The chart and the table fill in as you type. Nothing is sent anywhere and there is no account to create.
Where the detail lives
Payroll tax is set by each state and territory, so the rate that applies depends on where the wages are paid. Every figure is published with its source and the date it was last checked.
Frequently Asked Questions
Who has to register, how the threshold is split across states, how contractor doctors are treated, and what the Victorian surcharges add.
