Many people getting their tax notice of assessment wonder why they see amounts for the Medicare levy and Medicare levy surcharge. Here’s how it works.

Medicare Levy

The Medicare levy’s a compulsory charge that helps fund Australia’s public healthcare system. Almost all Australians pay this levy, which is 2% of your taxable income. The levy’s generally withheld from your pay by your employer throughout the year, so you may not notice it until tax time.

It’s important to note that having private health insurance doesn’t exempt you from paying the Medicare levy; it only affects your liability for the Medicare levy surcharge.

In certain limited cases, such as if you’re a low-income earner, a foreign resident or have a medical exemption, you may qualify for a reduced rate or full exemption.

Medicare Levy Surcharge

The Medicare levy surcharge (MLS) is an additional charge designed to encourage higher-income earners to take out private hospital insurance, reducing the strain on the public healthcare system. The MLS isn’t automatically withheld from your income, but is calculated when you lodge your tax return.

You may be liable for the MLS if your income exceeds the MLS threshold and you, your spouse and your dependent children don’t all have an appropriate level of private patient hospital cover for the entire income year. The surcharge rates vary based on your income tier, beginning at 1% for singles with 2025-26 income over $101,000 and families with income over $202,000.

Your income for MLS purposes includes several components beyond your taxable income, like reportable fringe benefits, total net investment losses and reportable super contributions. If you have a spouse, their income’s also considered.

Private Health Insurance

To avoid the MLS when your income’s over the threshold, you need an appropriate level of private patient hospital cover. Singles need a policy with an excess of $750 or less, and couples or families need a policy with an excess of $1,500 or less. Your policy must cover you, your spouse and all dependants for the full income year to avoid the surcharge.

Keep in mind that extras-only cover (such as for dental or optical) and travel insurance don’t qualify as private patient hospital cover for MLS purposes.
