The Medicare levy is a flat 2% of your taxable income that most Australian taxpayers pay to help fund the public health system. The Medicare Levy Surcharge is a separate, extra charge of 1% to 1.5% aimed at higher earners who do not hold an appropriate level of private hospital cover, and it is easy to confuse the two.
So there are really two things going on here, and they catch a lot of people out at tax time. One is the levy nearly everyone pays. The other is a surcharge that, with a bit of planning, plenty of people can avoid altogether.
What the Medicare levy actually is
The Medicare levy is 2% of your taxable income, and it is calculated as part of your tax return rather than being a separate bill. If your taxable income for the year was $80,000, the levy alone works out to roughly $1,600 on top of your income tax. It applies to most residents for tax purposes, and it is the standard contribution that helps pay for Medicare, the public system that covers things like GP visits, public hospital treatment and subsidised medicines.
A few important caveats. Low-income earners may pay a reduced levy or none at all, because the Australian Taxation Office sets thresholds below which the levy phases in gradually rather than hitting in full. There are also full or partial exemptions for some people, such as certain low earners, some foreign residents, and people who held a Medicare entitlement statement for part of the year. The exact thresholds shift each financial year, so treat any figure here as illustrative and confirm the current numbers with the ATO.
If you want to see how the levy interacts with the rest of your tax, a good income tax calculator for Australia will fold it into the estimate so you are not surprised by the final figure.
The Medicare Levy Surcharge is a different beast
Here is where it gets interesting. The Medicare Levy Surcharge, usually shortened to MLS, is an additional charge of between 1% and 1.5% of income for medicare levy surcharge purposes. It is designed to nudge higher-income earners towards private hospital cover so they lean less heavily on the public system.
Two conditions generally have to be met before the surcharge applies. First, your income for surcharge purposes needs to be above the relevant threshold, which differs for singles and families and steps up as income rises. Second, you do not hold an appropriate level of private hospital cover for yourself and your dependants. Meet both, and the surcharge applies on top of the ordinary 2% levy. Hold the right cover, and the surcharge simply does not apply, no matter how high your income.
That word “appropriate” matters. Extras or ancillary cover, the kind that pays for dental and physio, does not count. You need hospital cover that meets the qualifying standard. It is worth reading the fine print, or our broader guide to health insurance in Australia, before assuming a policy gets you over the line.
When private cover can be cheaper than the surcharge
This is the genuinely useful part. For some higher earners, a basic private hospital policy costs less over a year than the surcharge they would otherwise pay. In that situation you are spending money either way, so you may as well get an insurance product for it rather than handing the surcharge to the ATO and receiving nothing back.
The maths is personal and depends on your income, your family situation and the policy price, so it is worth running your own numbers. A good first step is to check whether private cover saves you tax and compare that against the surcharge you would face without it.
If a basic hospital policy costs less than the surcharge you would otherwise pay, you are buying cover with money you were going to lose anyway.
The catch is that this only works cleanly when the policy genuinely costs less than the surcharge. Buy an expensive policy you will never use purely to dodge a small surcharge, and you have not saved anything. Run the comparison honestly.
A quick way to see where you sit
Use this as a rough decision path, not gospel, and confirm the thresholds with the ATO for the current year.
- Work out your taxable income and your income for surcharge purposes, which can differ because the surcharge calculation adds back certain items.
- Check whether that surcharge income is above the relevant single or family threshold for the year.
- If it is below the threshold, you generally pay the 2% levy only and no surcharge.
- If it is above the threshold, check whether you held appropriate private hospital cover for the full year.
- No qualifying cover plus income over the threshold usually means the surcharge applies on top of the levy.
Levy versus surcharge at a glance
The table below is a simplified summary. Figures and thresholds change, so the rates are described in ranges rather than exact dollar amounts. Last checked June 2026.
| Feature | Medicare levy | Medicare Levy Surcharge |
|---|---|---|
| Who pays | Most taxpayers | Higher earners without appropriate private hospital cover |
| Rate | 2% of taxable income | 1% to 1.5% of surcharge income |
| Avoidable | Generally no, beyond low-income reductions or exemptions | Yes, by holding qualifying hospital cover or earning under the threshold |
| Purpose | Funds the public health system | Encourages private hospital cover among higher earners |
| Based on | Taxable income | Income for surcharge purposes |
How it shows up at tax time
You do not pay the levy or the surcharge as a separate invoice during the year. Both are reconciled when you lodge your return, which is one reason a surprise surcharge can sting. Your employer’s withholding may or may not have accounted for it, depending on what you told them, so the balancing happens at lodgement. If you are unsure how the figures flow through, our guide to lodging a tax return in Australia walks through where these amounts appear.
If you only held private hospital cover for part of the year, the surcharge can apply on a pro-rata basis for the uncovered days, which trips people up when they let a policy lapse mid-year. Keep your cover continuous if avoiding the surcharge is the goal.
A note on advice
This article is general information only. It is not personal financial, tax or legal advice, and it does not take your circumstances into account. Thresholds, rates and the rules around exemptions and qualifying cover change, sometimes from one financial year to the next. Before you act, confirm the current figures and your own position with the official source, which means the ATO for tax matters and your health fund for what your policy actually covers.
The bottom line
The Medicare levy is the easy bit: 2% of taxable income for most of us, with reductions or exemptions at the lower end. The surcharge is the part worth thinking about, because higher earners who skip private hospital cover can end up paying an extra 1% to 1.5% for nothing in return. Run your own numbers, check whether a basic policy beats the surcharge, and confirm the current thresholds with the ATO before tax time rather than after it.
