Guides
Australian payroll tax on a medical practice turns on two questions before any rate applies: whether payments to practitioners are deemed wages at all, and whether related entities are grouped into a single employer. These seven guides work through both, plus what is taxable, when to register, and how to correct a historical position now every amnesty window has closed.
Each guide states the position and cites the revenue office that administers it. Where the answer differs by jurisdiction — and for medical practices it usually does — the guide says so per state rather than generalising, because a rule that holds in Queensland may be the opposite of the rule in Victoria.
If you want a number rather than an explanation, the calculators and the medical practice tax overview are the faster route. These guides are for the cases where the answer depends on how your practice is structured.
Structuring and grouping
Who counts as one employer, and how the threshold is shared between them. Getting this wrong changes the answer before any rate is applied.
Multi-state apportionment
How a group's single threshold is split between the jurisdictions it operates in, and why the DGE nomination decides which entity can claim it.
Read the guideGrouping and DGE
When separate entities are treated as one employer for payroll tax, and how the Designated Group Employer nomination works in practice.
Read the guideWhat is taxable
Which payments are wages, which are exempt, and why a contractor with an ABN can still create a payroll tax liability.
What counts as wages
What is included in taxable wages — salaries, superannuation, fringe benefits and deemed contractor payments — and what is exempt.
Read the guideContractors and relevant contracts
The relevant contract provisions, the five harmonised exemptions, and the Thomas and Naaz precedent that reset medical practice payroll tax.
Read the guideContractor doctor payroll tax
Why contractor doctors create a payroll tax exposure, why an ABN does not change the answer, and the billing structure that avoids it.
Read the guideRegistering, lodging and correcting
When the obligation starts, what is due and when, and what to do now that every amnesty window has closed.
Registration and lodgement
When registration is triggered, the monthly return and annual reconciliation deadlines, and each jurisdiction's medical-specific obligations.
Read the guideAmnesties and audit pauses
The amnesty or audit pause that operated in each jurisdiction, the window and condition for each, and why every one has now closed.

Where should I start with payroll tax for a medical practice?
Start with the structure question, not the rate. How practitioners are engaged and how billings flow determines whether payments are deemed wages at all, and whether related entities are grouped determines how much threshold you have. Both change the answer before any rate is applied.
Do I need to read all seven guides?
No. If you engage contractor practitioners under a Service Facility Agreement, start with the contractor doctor guide. If you operate in more than one state, start with multi-state apportionment. If you only want to know what is due and when, the registration and lodgement guide is self-contained.
Are these guides tax advice?
No. They explain how the rules work, cite the administering revenue office for each jurisdiction, and link to the primary source. They are general information for Australian medical and health practices, not advice on your circumstances, and they do not replace a registered tax agent.
How current are these guides?
Each guide is dated and links to the revenue office that administers the rule. Rates and thresholds are drawn from the same verified registry the calculators use, so a legislative change updates the guide content and the calculators together rather than letting them drift apart.
