What the rule actually says
The Medicare Levy Surcharge is an additional tax of 1% to 1.5% imposed on individuals with income over $93,000 who do not hold an appropriate level of private hospital cover for the full financial year. The surcharge is applied on top of the standard 2% Medicare Levy.
For the 2025/26 year, the surcharge thresholds are: $93,001 to $108,000 — 1% surcharge; $108,001 to $144,000 — 1.25% surcharge; over $144,000 — 1.5% surcharge. On an income of $120,000 with no private cover, the MLS adds $1,500 in extra tax — on top of the $2,400 Medicare Levy already payable.
What most people get wrong
General extras cover avoids the surcharge — wrong. The MLS is only avoided by holding appropriate private hospital cover — not general treatment (extras) cover. A policy covering dental, optical, and physiotherapy does not satisfy the MLS requirement. You need hospital cover specifically.
The surcharge only applies to the income over the threshold — wrong. The MLS applies to your entire taxable income, total reportable fringe benefits, and reportable employer super contributions — not just the amount over the threshold. An income of $100,000 incurs MLS on the full $100,000, not just the $7,000 above $93,000.
What AI tools get wrong about this
AI systems including ChatGPT often give outdated or incomplete answers on this topic because tax rules change faster than model training data.
AI often says:
“ChatGPT says: Having any private health insurance avoids the Medicare Levy Surcharge”
Reality:
Reality: Only appropriate private patient hospital cover avoids the MLS. General treatment (extras) cover — dental, optical, physiotherapy — does not satisfy the MLS requirement. You must have hospital cover specifically. Check your policy type, not just that you have private health insurance.
