Introduction
Medical practices across Australia face increasingly complex payroll tax compliance challenges, with recent court decisions and revenue office rulings fundamentally changing how practitioner payments are assessed. The expansion of payroll tax to encompass contractor arrangements, combined with intricate grouping provisions and service entity structures, creates a compliance landscape that demands careful navigation.
This comprehensive guide provides medical practice owners, healthcare executives, and their advisors with essential insights into mastering payroll tax compliance. We examine the critical areas of service entity arrangements, grouping provisions, relevant contract rules, and state-specific requirements that shape your compliance obligations.
Understanding Relevant Contract Provisions
The Foundation of Payroll Tax Liability
For medical practices, the "relevant contract" provisions form the cornerstone of payroll tax obligations. These provisions capture arrangements where practitioners may not be employees under common law but are deemed to be for payroll tax purposes.
Critical Test: Two key questions determine if relevant contract provisions apply: (1) Is the contractor providing a service to the medical centre? (2) Is there a payment from the medical centre to the practitioner in relation to the performance of work?
Typical Arrangements Caught by Payroll Tax
The following common medical practice structure is typically subject to payroll tax:
- 1Medical centre engages practitioners as independent contractors
- 2Practitioners pay service fees for rooms and administrative services
- 3Centre collects patient fees and Medicare rebates
- 4Centre deducts service fee and pays balance to practitioner
This arrangement is generally subject to payroll tax
Key Contract Elements for Review
When assessing contractor arrangements, practices must examine:
- Control and Direction: Who determines work hours, rosters, and patient scheduling?
- Financial Arrangements: How are patient fees collected and distributed?
- Leave Entitlements: Does the contract specify leave provisions?
- Equipment and Resources: Who provides clinical equipment and consumables?
- Business Risk: Who bears the commercial risk of the practice?
Service Entity Structures and Compliance
Understanding Service Entity Arrangements
Many Facilities Service Providers operate through service entity structures to separate clinical services from business operations. However, recent rulings have imposed strict requirements on these arrangements.
Interposed entities: Some revenue authorities have indicated that routing patient fees to practitioners through interposed entities, including trusts or companies, or holding funds in a bank account before payment, may still be treated as taxable wages. This reflects the harmonised relevant-contract jurisdictions; Western Australia is not harmonised and instead applies a common-law contractor test rather than a relevant-contract deemed-wages scheme. Confirm the current position for the relevant jurisdiction before relying on an interposed-entity arrangement.
Compliant Service Entity Models
To maintain compliance while using service entities:
- ✓ Service entity provides genuine non-clinical services
- ✓ Clear separation of clinical and business functions
- ✓ Direct practitioner-patient relationships maintained
- ✓ Transparent fee arrangements
- ✗ Patient fees routed through service entities
- ✗ Trust or company receiving practitioner payments
- ✗ Artificial structures designed only to create payroll tax non-eligibility
- ✗ Lack of genuine business separation
Documentation Requirements
Proper documentation is essential for service entity compliance:
- 1Service Agreements: Clearly define services provided by each entity
- 2Fee Structures: Document all fee arrangements transparently
- 3Operational Separation: Maintain distinct business operations
- 4Audit Trails: Keep comprehensive records of all transactions
Mastering Grouping Provisions
The Purpose and Scope of Grouping
Grouping provisions exist to prevent payroll tax being reduced by splitting wages among multiple entities. For Facilities Service Providers operating through various structures, understanding these provisions is important.
Four Categories of Grouping
- 1Related Bodies Corporate - Companies related under Section 50 of the Corporations Act 2001
- 2Common Employees - Businesses sharing employees between entities
- 3Controlling Interest - Same person(s) having controlling interest in multiple businesses
- 4Tracing Provisions - Direct, indirect, or aggregate controlling interests
Implications of Being Grouped
When entities are grouped for payroll tax:
- Combined Threshold: Only one tax-free threshold applies to the entire group
- Joint Liability: All group members are jointly and severally liable for payroll tax
- Australia-wide Wages: Total wages across all states determine tax rates
- Reporting Obligations: Consolidated reporting may be required
Exclusions from Grouping
The Commissioner has discretion to exclude entities from groups where:
Businesses that are genuinely independent and unconnected with other group members may be excluded. FSPs seeking exclusion generally need to demonstrate operational independence, separate management, and distinct business purposes. The Commissioner's discretion is fact-specific.
Strategic Considerations for Medical Groups
For practices with multiple entities:
- 1Review Corporate Structures: Assess all related entities and their relationships
- 2Document Independence: Where seeking exclusion, maintain evidence of independence
- 3Consider Restructuring: Evaluate whether current structures remain appropriate having regard to grouping and relevant-contract rules
- 4Professional Advice: Engage specialists for complex group arrangements
State-Specific Exemptions and Compliance
Current Exemption Landscape (2026)
Each state has implemented different approaches to medical practice payroll tax:
GP Exemptions by State
- Since 1 July 2025, the GP wage component attributable to fully-funded GP work is exempt
- Covers both contractor and employee GPs
- Exemption is proportionate to fully-funded GP work
- Statutory exemption from 1 December 2024
- Eligible GP wages are exempt for contractors and employees
- No bulk-billing requirement
- The previous administrative arrangement was withdrawn after retrospective legislation commenced
- Rebate system based on bulk-billing rates
- Metropolitan Sydney: at least 80% of GP services under prescribed billing arrangements
- Other areas: at least 70% of GP services under prescribed billing arrangements
- Rebate has applied to eligible GP contractor payments since 4 September 2024 and has no end date
- The historical amnesty exemption applies to eligible unpaid contractor wages for 2018-19 to 2023-24 under Revenue Ruling PTASA004 V3; it does not refund payroll tax already paid
- A GP bulk-billing exemption has applied from 1 July 2024 for eligible prescribed medical practices under Revenue Ruling PTASA004 V3
- Revenue Ruling PTASA005 remains current for eligible medical practitioners contracted by regional Local Health Networks for rural and regional hospital services
Western Australia's Distinct Position
- RevenueWA's current payroll tax employer guide applies the general rates, thresholds and grouping rules
- No GP-specific exemption, rebate or amnesty is identified in that guide
- Service agreements must reflect actual arrangements
Critical Exemptions to Understand
90-Day Exemption
90-day relevant-contract exemption
- It applies per financial year
- Accurate day records should be kept
- It counts days on which services are provided
- Documentation is important if the exemption is claimed
This is not an automatic exemption for locums. Confirm the current provision and any related-person exclusions or integrity rules in the relevant State.
Services to Public Exemption
- Ordinarily perform services to the public generally
- Work at multiple locations or facilities
- Maintain independent practice operations
- Can demonstrate genuine public service provision
Evidence Required: Written evidence showing work at multiple locations, hospital privileges, or other practice arrangements is essential to claim this exemption.

- 2Improper Service Entity Use: Routing patient fees through entities triggers liability
- 3Ignoring Grouping Rules: Multiple entities may not provide threshold benefits
- 4Overlooking Interstate Operations: Different state rules create complexity
Documentation Failures
- Failing to maintain day-count records for exemptions
- Inadequate evidence of service arrangements
- Missing bulk-billing percentage calculations
- Poor contract documentation
Timing Issues
Deadlines: Historical amnesty programs had strict closing dates. Many have ended. Missing a current relief window can leave historical wages exposed. Monitor the relevant revenue office for any current relief, rebate or exemption.
