How does an associate dentist pay split usually work?

Most practices pay associates a percentage of the billings they generate, commonly between 40% and 50%, after deducting lab fees. The practice keeps the remainder to cover overheads, equipment, reception and its own margin. The exact split varies by practice and experience level.

Do associate dentists charge GST on their invoices?

If the associate is operating as a genuine contractor and is GST registered, yes — their invoice to the practice should include GST, which the practice claims back as an input tax credit. This needs to be set up correctly in Xero from the first invoice.

How should lab fees be handled in an associate split?

Lab fees are typically deducted from billings before the split is calculated, since they're a direct cost of the treatment provided. This needs to be tracked accurately per associate, not lumped into general practice expenses, so each split calculation is correct.

Q: Is an associate dentist a contractor or an employee?

This depends on the actual working arrangement, not just what the contract says. Genuine contractor arrangements involve real independence — the associate invoices the practice, manages their own tax and super, and isn't directed like an employee. Getting this classification wrong creates serious payroll tax and superannuation exposure.

How Associate Splits Typically Work

Most Melbourne dental practices pay associates a percentage of the billings they generate, commonly 40–50%, calculated after lab fees are deducted. The practice retains the remainder to cover overheads, equipment, reception staff and its own margin. The exact percentage varies by practice, location and the associate's experience.

Contractor or Employee? Get This Right First

This classification matters far more than most practices realise. A genuine contractor arrangement requires real independence — the associate invoices the practice, manages their own tax and superannuation, and isn't directed in the way an employee would be. If the actual working relationship looks more like employment, treating someone as a contractor creates serious exposure to back-payment of payroll tax and superannuation guarantee charges.

        Common mistake: a contract labelled "contractor agreement" doesn't change the actual classification if the working relationship functions like employment. The ATO and Fair Work look at substance, not just the paperwork.
      

GST on Associate Invoices

If the associate is a genuine, GST-registered contractor, their invoice to the practice includes GST, which the practice claims back as an input tax credit. This needs correct GST coding in Xero from the very first invoice — getting it wrong understates input credits and overstates what the practice actually owes.

Lab Fees Need to Be Tracked Per Associate

Lab fees are typically deducted from billings before calculating the split, since they're a direct cost of the treatment. This means lab fees need to be tracked accurately against each associate's billings, not lumped into general practice expenses — otherwise every split calculation downstream is wrong.
