Why a practice tax check matters in 2026
Since the Thomas and Naaz decision was upheld by the NSW Court of Appeal in April 2024, every state revenue office has treated contractor doctor arrangements as a priority audit area. Arrangements that were standard for a decade — service agreements, facility fees, tenant GP leases — are the first thing an auditor tests, and payroll tax is assessed on those payments as if they were wages, with retrospective assessments, interest and penalty tax all in play.
The exposures rarely arrive one at a time. A practice that engages contractor doctors usually also sits inside a group, invoices through practitioner entities, and pays contractors who may attract superannuation — so a single-rule answer is not enough. The check walks the whole structure in one pass and tells you which of the eight areas actually needs attention, with a direct link to the calculator or guide that works out the dollars.
One honest limitation: a self-assessment scores what you can see. It cannot read your agreements or your lodgement history. Where the check flags contractor arrangements or grouping, the score is a prompt to have the documents reviewed, not a clearance.
What the check covers, domain by domain
Payroll tax registration. Whether your group's combined wages exceed your state's threshold, and whether you are registered in every state where you pay wages or engage contractors — a practice can owe payroll tax in a state where it has no employees.
Contractor doctor arrangements. The relevant contracts tests that the revenue offices now apply first: what the agreement says, what happens in practice, and whether it has been reviewed since Thomas and Naaz.
Grouping and DGE. Whether related entities share your threshold, who the designated group employer is, and what that does to the group's total liability.
State exemptions. The GP exemptions (Victoria's 80% exemption with caps, Queensland's exclusion for eligible GP and specialist services) and the 90-day contractor exemption, each of which turns on how the practitioner actually works.
Structure and PSI. Whether practitioners invoicing through companies or trusts have documented results tests, and what the PSI rules would do if they do not.
GST, super and Division 7A. Whether your service mix is really all GST-free, which contractors attract superannuation under s 12(3) regardless of their ABN, and whether related-party loans need minimum Division 7A repayments.
Practice tax check: frequently asked questions
What is a practice tax check?
A practice tax check is a structured review of the tax exposures that apply to an Australian healthcare practice: payroll tax registration and thresholds, payments to contractor doctors, grouping and the designated group employer rules, state exemptions, personal services income, GST on health services, and Division 7A. This check scores each area and produces a prioritised action list in about 10 minutes.
Is the practice tax check really free?
Yes. The check is free, needs no signup, and runs entirely in your browser — the answers are never uploaded. PracticeTax is published by eHealth Systems Pty Ltd (ABN 29 647 383 588) and the questions are built on the same verified rates and rules that power the site's calculators.
What taxes does a healthcare practice pay in Australia?
A typical practice deals with payroll tax (state-based, on wages and many contractor payments), GST and BAS obligations, superannuation guarantee, PAYG withholding, the personal services income rules for practitioner entities, and Division 7A where the practice entity has lent money to directors, shareholders or related trusts. The check above covers all of these areas in one pass.
Do medical practices pay payroll tax on contractor doctors?
Often yes. Under the relevant contracts rules, payments to contractor doctors can be taxable wages for the practice even though the doctors are not employees. The Thomas and Naaz litigation confirmed that common GP arrangements are caught, and revenue offices across the states have since made medical practice contractor arrangements a priority audit area.
What is the Thomas and Naaz decision and why does it matter?
Thomas and Naaz Pty Ltd v Chief Commissioner of State Revenue was decided by the NSW Supreme Court in 2023 and upheld by the NSW Court of Appeal in April 2024. It held that payments under the practices' doctor arrangements were relevant contracts and therefore taxable wages. It is now the reference point every state revenue office brings to a medical practice audit, which is why agreements drafted before 2024 should be reviewed against it.
Which states exempt GP wages from payroll tax?
Victoria applies a payroll tax exemption for 80% of eligible GP wages up to annual caps, and Queensland excludes wages for eligible GP and specialist services delivered to the public. New South Wales has no GP exemption — a flat 5.45% applies above the $1.2 million threshold. Check the state page for your jurisdiction for caps, eligibility conditions and current dates.
What is the 90-day contractor exemption?
Most state payroll tax laws provide an exemption for services under a relevant contract where the contractor provides services to the practice on no more than 90 days in a financial year. The days are counted across the whole grouped group, the conditions vary by state, and the exemption is lost by assumption — a simple day log per contractor is the evidence that settles it.
How does grouping affect my practice's payroll tax?
Related businesses — those with common owners, directors or trustees, or that use common employees — can be grouped, and a group shares a single payroll tax threshold rather than one each. Only the designated group employer (DGE) claims the threshold, which is why DGE status and the annual election matter for any practice operating through more than one entity.
What is a designated group employer (DGE)?
Where several entities are grouped for payroll tax, the members can elect a designated group employer. The DGE pays payroll tax on the group's combined Australian wages and is the only member that can claim the threshold. A non-DGE member pays tax on its wages from dollar one, so getting the election wrong changes the group's total liability.
How do the personal services income (PSI) rules affect doctors?
Where a practitioner earns most of their income from personal efforts — commonly through a company or trust invoicing the practice — the PSI rules can attribute that income back to them personally unless the entity passes the results test. A documented results test for each practitioner entity is the core evidence, and it should be refreshed whenever the arrangement changes.
Is GST payable on medical services?
Most health services that are Medicare-eligible (or would be) are GST-free under s 38-7 of the GST law, which is why a typical GP practice charges no GST and still claims input tax credits. Most cosmetic procedures, medical reports for third parties such as insurers or employers, and some non-clinical services are taxable. A practice providing a mix of both needs to register and apportion correctly.
How often should I run a practice tax check?
At least once a financial year, and always after a structural change: adding a contractor or a location, crossing a wage threshold, forming or joining a group, or changing how practitioners are engaged. The check takes about 10 minutes and flags which answers create exposure.
