Medical and healthcare practices are among the most bookkeeping-intensive businesses an accountant or bookkeeper can work with. The GST treatment of health services is not straightforward, contractor arrangements with GPs create employment classification complexity, and multi-disciplinary clinics often blend taxable and exempt revenue streams in ways that require careful separation. Here is what every bookkeeper working in this sector needs to understand.
GST-Free Health Services: What Qualifies
Under the GST Act, most health services are GST-free when provided by a recognised health professional to treat an individual patient. The ATO's list of recognised health professionals is specific and includes medical practitioners, nurses, dentists, optometrists, chiropractors, physiotherapists, psychologists, and speech pathologists, among others.
The key conditions for GST-free treatment:
- The supply must be a health service (treatment, examination, or advice relating to health).
- It must be provided by (or on behalf of) a recognised health professional.
- It must be generally accepted in Australia as appropriate treatment.
The last condition is what makes complementary medicine tricky. Naturopathy, homeopathy, and some other complementary services are not universally GST-free — it depends on the specific practitioner's registration and the nature of the service. When in doubt, seek a private binding ruling rather than assuming.
Mixed Supplies: Where Practices Go Wrong
Most clinics do not deliver exclusively GST-free services. Common taxable supplies in healthcare settings include:
- Cosmetic procedures not for medical reasons (laser hair removal, Botox for cosmetic purposes, skin treatments)
- Sale of products — supplements, orthotics, glasses frames above the basic level, health foods
- Gym memberships or fitness classes attached to a clinic
- Administrative fees (copying of medical records, missed appointment fees in some interpretations)
- Workcover and insurance reports — these are taxable supplies, not health services
When a clinic has mixed supplies, the bookkeeper must apportion costs appropriately. Direct costs (a consultation room used only for Medicare-billed services) can be fully attributed to the GST-free stream. Overhead costs (reception staff, rent, utilities) need apportionment based on a reasonable method — revenue ratio, floor area, or time are all acceptable, but the method must be documented and applied consistently.
Pathology and Diagnostic Services
Pathology services, radiology, and other diagnostic services are generally GST-free when the service is performed for the purpose of diagnosing or monitoring a medical condition. The complication arises with specimen collection centres (which may charge a co-payment) and diagnostic equipment hired or leased to the practice. Equipment leases are taxable — a clinic cannot claim that a MRI machine lease is GST-free simply because it produces GST-free services.
Contractor GPs: The Employment Status Issue
Many general practices engage GPs as contractors rather than employees. This arrangement has significant bookkeeping and tax implications:
If the GP is a genuine contractor, the practice pays a service fee (often a percentage of billings), the GP invoices the practice (and must have their own ABN), and the GP is responsible for their own GST registration, superannuation, and tax. The practice records the service fee as a contractor expense and can claim an ITC if GST is charged.
If the arrangement does not pass the contractor tests (the ATO's multi-factor test looks at control, integration, results-based payment, and more), the GP may be deemed an employee for PAYG withholding and superannuation purposes — regardless of what the contract says. The Superannuation Guarantee applies to contractor arrangements where the person works under a contract that is wholly or principally for their labour.
Bookkeepers should flag any contractor arrangement where the same person works regular hours at a single clinic to the supervising accountant. The personal services income rules may also be relevant.
Payroll Complexity in Multi-Disciplinary Clinics
Healthcare payroll is complicated by award coverage. Most allied health employees fall under the Health Professionals and Support Services Award, while medical receptionists may fall under the Clerks Award. Correctly identifying the applicable award, classification level, and entitlements (including weekend penalties, overtime, and allowances) is essential before setting up payroll.
Nurses are covered by their own award. If a practice employs both nurses and administrative staff, two separate award frameworks apply simultaneously. STP Phase 2 reporting requires each income type to be correctly disaggregated — salary sacrifice, allowances, and leave must be separately identified in payroll.
Payroll tax thresholds also catch healthcare practices. In a large state like Victoria or NSW, a practice with several employed GPs and allied health staff can clear the payroll tax threshold without realising it, particularly if related entities are grouped for assessment purposes.
Practical Steps for Bookkeepers Taking On a Healthcare Client
When onboarding a medical or healthcare client, work through this checklist before touching any transactions:
- Map every revenue stream and classify it as GST-free, taxable, or input-taxed.
- Review all contractor arrangements and assess genuine contractor status.
- Identify all applicable awards for payroll staff and confirm classification levels.
- Set up separate income accounts for GST-free and taxable revenue in the COA.
- Establish an apportionment methodology for shared overhead costs and document it.
- Check whether the practice participates in bulk billing — billing agents sometimes have their own GST implications.
Healthcare bookkeeping rewards accuracy and domain knowledge. Getting the GST classification right at the transaction level saves significant rework at BAS time and protects the client from ATO scrutiny.
