GP Contractor vs Employee: Payroll and Tax Implications

Why This Classification Matters More Than It Used To

Medical practice arrangements involving GPs working under service agreements have been specifically targeted by state revenue offices in recent years, with payroll tax assessments applied retrospectively to clinics that assumed their doctors were straightforward contractors. This makes correct classification — and proper documentation of the actual working arrangement — more important than it's ever been.

What Determines the Classification

Most GPs working under a service agreement bill the clinic or patients directly and manage their own tax and superannuation, which points toward genuine contractor status. But the label in the agreement doesn't settle the question on its own — control over hours, exclusivity arrangements, and exactly how billing and payment flow through the practice all factor into the actual classification.

Superannuation Can Still Apply to Contractors

Superannuation guarantee obligations can extend to contractors paid principally for their labour, regardless of how the relationship is labelled in the service agreement. This is a commonly underestimated obligation — clinics assume "contractor" means no super obligation, which isn't necessarily correct.

What a Clinic Should Actually Do

• Document the real arrangement — how billing actually flows, who controls scheduling, and the degree of independence in practice.
• Get specific advice — given the payroll tax exposure for medical practices, generic templates aren't enough.
• Review existing arrangements — don't assume historical classifications are still correct as service agreements evolve.

Why a Bookkeeper's Involvement Matters Here

A bookkeeper who understands medical practice structures can flag where the bookkeeping evidence (how payments actually flow, what's recorded where) doesn't match the stated classification — often before it becomes a problem during an audit or review.
