Allied health is one of the highest-risk sectors for GST classification errors because practitioners routinely supply both GST-free therapeutic services and taxable non-therapeutic services from the same premises, sometimes within the same client appointment.
GST-Free Health Services: Scope and Limits
The GST-free health services provisions in Subdivision 38-B of the GST Act exempt supplies made by recognised health professionals in their professional capacity. Physiotherapists, chiropractors, osteopaths, speech pathologists, occupational therapists, podiatrists, optometrists, audiologists, and psychologists all fall within the definition of "recognised health professional" for GST purposes.
The exemption applies to services that are generally accepted in the health profession as being necessary for the appropriate treatment of the patient's condition. This means an initial assessment, treatment sessions, and home exercise programs produced in the course of treating a clinical condition are all GST-free.
The exemption does not apply to services that are not directly connected to treatment: gym memberships sold by the physio clinic, sports performance coaching with no clinical component, workplace ergonomic assessments for healthy workers (contested — some fall within the exemption, some do not depending on the clinical context), and cosmetic or aesthetic treatments. Botulinum toxin (Botox) injections and cosmetic injectables supplied even by registered health professionals are taxable supplies — they do not treat a recognised condition. The bookkeeper must set up separate income accounts for GST-free therapeutic revenue and taxable non-therapeutic revenue, and ensure the HICAPS terminal coding matches the tax treatment of each service type.
Private Health Fund Payments and HICAPS Reconciliation
Physiotherapy is not covered by Medicare, unlike GP and specialist consultations. Revenue flows from a mix of private health fund gap payments (via HICAPS), DVA-funded sessions, WorkCover claims, and direct patient payments. The HICAPS terminal splits each appointment into a health fund benefit (paid directly to the clinic) and a patient gap (paid by the patient). The clinic receives two streams for the one service.
The HICAPS settlement report summarises daily transactions and is the source document for reconciling health fund receipts against the practice management system. Common reconciliation issues include: HICAPS settlements arriving in the bank account 1–2 business days after the appointment date (creating timing differences); claim adjustments and reversals processed after the original settlement; and the health fund retaining amounts from current settlements to recover previously overpaid benefits. Each of these requires a systematic reconciliation process in the bookkeeping workflow, not just matching individual deposits.
NDIS Service Delivery: Pricing, GST, and Payment Flows
Allied health services provided to NDIS participants — physiotherapy, occupational therapy, speech pathology, psychology — are billed against the NDIS Support Catalogue rates. These services are GST-free for the same reasons as private practice services: they are therapeutic health services supplied by recognised health professionals.
The payment mechanics vary by plan management type. For agency-managed participants, the provider claims directly through the NDIS myplace portal (or via the bulk payment request system for high-volume providers), and the NDIA pays within approximately three business days of a claim being approved. For plan-managed participants, the provider invoices the plan manager, who pays the provider and then claims reimbursement from the NDIA. Accounts receivable management differs substantially between these two pathways — plan manager payment terms can be 30 days or longer.
NDIS pricing is set by the NDIA in the Support Catalogue and is reviewed annually. The bookkeeper should ensure the practice management system's rate tables are updated each 1 July when the new pricing takes effect. Overbilling the NDIS (even inadvertently) carries significant compliance consequences under the NDIS Act 2013 and the fraud provisions of the Criminal Code.
Contractor vs. Employee: The Room Rental Test
The room rental model is pervasive in allied health: a practitioner leases a treatment room from the clinic operator, pays a room fee per session or as a percentage of billings, and ostensibly operates as an independent business. The arrangement reduces the clinic operator's payroll tax, superannuation, and workers' compensation costs — but only if the practitioners are genuinely independent contractors.
The Full Federal Court's decision in CFMMEU v Personnel Contracting (2022) confirmed that the totality of the legal relationship, as expressed in the contract, determines the status. In many allied health room rental arrangements, the clinic controls the appointment booking system, retains the health fund payments and the HICAPS terminal, sets or approves the fee schedule, and remits the net payment to the practitioner. In this structure the practitioner is not billing their own patients — the clinic is. The economic and legal reality is employment, and the room rental fee is a method of disguising a wage.
Where practitioners are misclassified as contractors, the clinic operator is liable for unpaid SGC (including the ATO SGC uplift), PAYG withholding, and potentially payroll tax — all on a retrospective basis. The ATO's contractor vs. employee guidance and the multi-factor test in Taxation Ruling TR 2023/4 should be applied to each practitioner arrangement annually.
Equipment Finance and Capital Allowances
Physiotherapy clinics invest heavily in treatment and diagnostic equipment — ultrasound machines, electrotherapy units, traction tables, shockwave therapy devices, and hydrotherapy pools. Under the instant asset write-off provisions, equipment costing under the applicable threshold and used principally for income-producing purposes can be immediately deducted in the year of acquisition.
The key distinction for capital works is between plant (Div. 40) and building improvements (Div. 43). A hydrotherapy pool that is a freestanding above-ground unit installed in a leased premises is likely plant. A hydrotherapy pool that is an excavated below-ground structure forming part of the building is a capital work and must be depreciated over 40 years under Div. 43 — it cannot be instantly written off. Structural modifications to the building to accommodate heavy treatment equipment (reinforced flooring, specialised plumbing) are similarly capital works. The bookkeeper should obtain quotes that separate the cost of the equipment from any structural installation costs to allow correct categorisation.
