Calculate the Australian Medicare Levy and Medicare Levy Surcharge for sole traders and self-employed workers.
Last updated: February 23, 2026
Enter your net income from self-employment (business schedule).
Self-employed individuals (sole traders) in Australia do not pay a separate self-employment tax like in the US. However, you are subject to the Medicare Levy and potentially the Medicare Levy Surcharge (MLS).
The MLS is an additional charge for taxpayers who earn above a certain threshold and do not hold an appropriate level of private health insurance. If you earn over $75,000 per year from your business, you must also register for GST.
