If you earn above a certain income and don't have private hospital cover, the Australian Government charges you an extra tax at the end of the financial year. It's called the Medicare Levy Surcharge (MLS), and a lot of Australians don't realise they're paying it until they lodge their return.
The good news: it's avoidable. And with thresholds changing for 2026–27, now is a good time to check exactly where you stand.
What is the Medicare Levy Surcharge?
The Medicare Levy Surcharge (MLS) is a tax on top of the standard 2% Medicare Levy that all Australian taxpayers pay. It exists to encourage higher earners to take out private hospital cover and take some pressure off the public health system.
The surcharge ranges from 1% to 1.5% of your income depending on how much you earn and it only applies if you don't hold an eligible private hospital policy for the full year.
A few things worth knowing about the MLS:
- It's not the same as the Medicare Levy. Everyone pays the 2% Medicare Levy. The MLS is an additional charge on top of that, and only applies to people above the income threshold without cover.
- Extras-only cover doesn't count. You need hospital cover specifically. A policy that only covers things like dental and physio won't exempt you from the surcharge.
- It's calculated on more than just your salary. Your income for MLS purposes includes reportable fringe benefits and net investment losses, not just your taxable income.
- It's pro-rata. If you had cover for part of the year, you'll only be charged for the days you were uninsured.
The 2026-27 financial year thresholds
The income thresholds that trigger the MLS are indexed each year. For the 2026–27 financial year, the entry points have increased:
- Singles: $105,001 (up from $101,000 in 2025–26)
- Couples and families: $210,001 (up from $202,000 in 2025–26)
- Family threshold: increases by $1,500 for each dependent child after the first
If your income sits above these figures and you don't hold eligible hospital cover, you'll pay the surcharge on your next tax return. If you've had a pay rise recently, you're right on the edge, it's worth checking your position now rather than getting a surprise bill later.
How to use the Finder MLS calculator
The calculator below is designed to give you a quick, clear picture of your MLS position for 2026–27. Here's how to use it:
- Enter your income: Plug in your annual income and state.
- Select your cover status: Tell the calculator whether you currently hold eligible private hospital cover and for how many days of the financial year.
- Add family details if relevant: If you have a spouse or dependants, enter your combined household income to get an accurate result.
- See your result: The calculator will show your estimated MLS liability and some of the cheaper options based on your circumstances.
What's next?
If the calculator shows you're better off with cover, it's worth comparing your options. Basic hospital policies can start from as little as a few dollars a day, and with the government rebate factored in, the real cost is often lower than people expect.
Use the health insurance quiz above to compare policies and find one that fits your budget. You might be surprised how little it takes to avoid the surcharge entirely.
