Are speech pathology services GST-free?

Clinical speech pathology services generally qualify as GST-free health supplies when provided to the patient as accepted treatment. But medico-legal reports, some third-party assessments, supervision fees and product sales can be taxable. A growing practice needs each revenue type coded deliberately, not a blanket GST-free assumption.

What happens if an NDIS claim misses the 90-day window?

Claims for agency-managed participants must be submitted within 90 days of the end of the service booking. Miss it and the practice generally wears the loss for work already delivered. A monthly reconciliation between practice software and portal remittances is the reliable way to catch unclaimed sessions while they can still be lodged.

When does an allied health practice need to worry about payroll tax?

When total wages, including some contractor payments, approach your state's threshold. Victoria's threshold catches practices earlier than many owners expect once several clinicians are on board. How practitioner agreements are structured and recorded in the books matters, because revenue offices are actively reviewing health practices' contractor arrangements.

What should a group practice see in its monthly reports?

Revenue by stream and by clinician, utilisation against available hours, unclaimed or unpaid sessions by funding type, payroll cost against revenue, and cash cover in weeks. Those five numbers tell an owner more than a standard profit and loss ever will.

What does bookkeeping cost for a group practice?

Fixed monthly pricing quoted after a free file assessment. Multi-clinician practices typically land between $600 and $1,200 or more per month depending on claim volume, payroll size and reporting depth. You will know the exact number before committing.

Bookkeeping for Speech Pathology and Allied Health Group Practices

Published July 2026By True Tally Bookkeeping9 min read

The short answer: bookkeeping for a speech pathology or allied health group practice is mostly about reconciling money that arrives in bulk against work delivered one session at a time. NDIS batches, Medicare deposits, health fund payments and private fees all land differently and carry different GST and reporting rules. A practice bookkeeper's job is making sure every session delivered becomes money received, on time, correctly coded, and visible per clinician.

Key takeaways

Group practices juggle four revenue streams with different rules: NDIS, Medicare, private health funds and private fees. Each needs its own handling in the books.
NDIS claims have a 90-day window and strict line-item pricing. Late or miscoded claims are revenue you already earned and simply lost.
GST in allied health is not one rule: most clinical services are GST-free, but reports, some assessments and product sales may not be.
As a practice grows past three or four clinicians, payroll and per-clinician reporting become the difference between busy and profitable.

The Four Revenue Streams and Where Each One Leaks

Revenue stream	How it arrives	Where practices lose money
NDIS	Portal claims (agency-managed), invoices to plan managers, or invoices to participants	Claims outside the 90-day window, wrong line items, price-limit breaches
Medicare	Bulk deposits covering many sessions	Deposits never matched to individual sessions, so gaps go unnoticed
Private health funds	HICAPS and fund batch payments	Batches that do not reconcile to the bank, rejected claims never resubmitted
Private fees	Card, invoice or on-the-day payment	Unpaid invoices nobody chases because nobody owns the list

Every one of those leaks is invisible in a file that just reconciles the bank. The deposit arrived, the software matched it, everything looks fine. Whether it was all the money you were owed is a different question, and it is the one that matters.

The NDIS Layer

For practices with significant NDIS caseloads, the billing rules are unforgiving: claims must be lodged within 90 days of the end of the service booking, line items must match the support delivered, and prices must sit within the published limits. The bookkeeping side is a monthly reconciliation between your practice software, the portal remittances and the bank, so that every delivered session is claimed, every claim is paid and every rejection is followed up while it can still be fixed. We cover the provider side in more depth in our NDIS bookkeeping service and the companion guide to bookkeeping for NDIS providers.

GST: Not One Rule, Several

Most clinical allied health services are GST-free when they meet the health supply rules. But the moment a practice grows, edge cases multiply: medico-legal reports, some workplace assessments, supervision sold to other providers, product sales, room rental to contractors. Coding everything GST-free because "health is GST-free" is one of the most common errors we find in practice files, and it surfaces at the worst time, during an ATO review.

Growing From Solo to Network: What Changes in the Books

Practice size	What the books must add
Solo clinician	Clean revenue-stream tracking, quarterly BAS, simple payroll or drawings
2 to 4 clinicians	Payroll under the Health Professionals award, per-clinician revenue, utilisation visibility
5 to 15 clinicians	Contractor versus employee treatment done properly, month-end management reports, cash flow forecasting
Multi-site network	Per-site profitability, consolidated reporting, payroll tax registration and monitoring across states

That last row deserves emphasis. Once a network's wages bill approaches the state payroll tax threshold, and how practitioner contractors are engaged and recorded starts to carry payroll tax consequences, the books stop being an admin function and become the practice's early-warning system. This is the same contractor scrutiny currently hitting medical centres, and allied health networks are not exempt from it.

Utilisation: the Number That Decides Your Next Hire

Revenue tells you what happened. Utilisation tells you why. When each clinician's delivered hours are visible against their available hours every month, the growth decisions make themselves: a practice sitting at 90% utilisation across the team is leaving referrals on the table and can hire with confidence, while one at 60% has a booking or retention problem that a new hire would only dilute. Very few practice owners have this number, not because it is hard to calculate, but because their books were never structured to produce it. It is the single most valuable report a group practice can add, and it falls straight out of bookkeeping that tracks revenue per clinician.

What to Ask a Bookkeeper Before Handing Over a Practice File

"Have you reconciled NDIS portal remittances against practice software before?"
"How do you handle the GST split between clinical services and everything else?"
"Have you run payroll under the Health Professionals and Support Services award?"
"Can you show revenue and utilisation per clinician, per month?"
"Are you a registered BAS agent?" Verify at tpb.gov.au.

The Bottom Line

A growing allied health practice does not usually have a revenue problem, it has a reconciliation problem. The work is being done; the money is arriving in bulk and nobody can prove it all arrived. Fix the books so every stream reconciles monthly and every clinician's numbers are visible, and the practice gets calmer and more profitable at the same time.
