ATO benchmarks for dentists

General dentists earn from check-ups, cleans, fillings, crowns and other treatment paid for by patients and their health funds, while dental assistants, surgery rent, lab fees and consumables are their main costs.

General information

These are the Australian Taxation Office's published small business benchmarks for dentists, shown as the ATO publishes them for each turnover range. They describe the industry as a whole, not any one business, and they are not advice about a particular business. Sources checked 15 October 2026.

What sits behind these figures in the books

  • The main expense lines are staff costs for dental assistants and reception, surgery rent, lab fees for crowns and dentures, clinical consumables, equipment servicing and insurance.
  • Supplier orders for gloves, anaesthetic, impression materials and filling materials are entered from their bills as they arrive, so consumables are counted in the period they were bought.
  • A new dental chair, X-ray unit or steriliser is recorded apart from running costs, so total expenses reflect the cost of seeing patients from day to day.
