Medicare Levy Surcharge Calculator: How Much Extra Tax Will You Pay in 2025-26?

If you're a higher-income earner in Australia without private hospital cover, you might be paying more tax than you need to. The Medicare Levy Surcharge (MLS) is an additional tax charged on top of the standard Medicare Levy, and it can add hundreds—or even thousands—of dollars to your annual tax bill. The good news? This surcharge is entirely avoidable with the right health insurance. In this guide, we'll walk you through everything you need to know about the MLS, including the 2025-26 income thresholds, surcharge rates, and how to use a Medicare Levy Surcharge calculator to estimate your liability.

What Is the Medicare Levy Surcharge?

The Medicare Levy Surcharge is an extra tax designed to encourage higher-income Australians to take out private hospital cover and reduce the burden on the public Medicare system. Unlike the standard Medicare Levy—which applies to most taxpayers—the MLS only affects those who earn above certain income thresholds and don't have an appropriate level of private hospital insurance.

It's important to distinguish between the two: the Medicare Levy is a universal charge (currently 2% of taxable income) that nearly everyone pays to fund Australia's public health system. The Medicare Levy Surcharge, on the other hand, is an additional penalty ranging from 1% to 1.5% of your income, depending on how much you earn. If you're confused about your overall tax obligations, our income tax calculator can help you understand your complete tax picture, including levies and surcharges.

The Australian government introduced the MLS in 1997 to encourage people who could afford private health insurance to use the private hospital system, thereby freeing up public hospital resources for those who need them most. While some view it as a penalty, others see it as an incentive to get better health coverage while potentially saving money on taxes.

Medicare Levy Surcharge Income Thresholds for 2025-26

The MLS income thresholds are adjusted each financial year based on average weekly earnings. For the 2025-26 financial year, the thresholds remain consistent with the 2024-25 levels. Your liability depends on your income tier and whether you're single or have a family.

Here's the complete breakdown of the Medicare Levy Surcharge tiers for 2025-26:

Note: The family income threshold increases by $1,500 for each MLS dependent child after the first. If you have a partner, your combined income determines your family threshold.

If your income falls below these thresholds ($97,000 or less for singles, $194,000 or less for families), you won't pay the Medicare Levy Surcharge, regardless of whether you have private health insurance. However, crossing even slightly into Tier 1 means you'll owe an additional 1% of your entire income in tax if you don't have hospital cover.

For example, if you're single earning $100,000 in 2025-26 without private hospital cover, you'll pay $1,000 in MLS on top of your regular income tax and the standard Medicare Levy. That's money that could potentially be better spent on actual health insurance.

How to Calculate Your Medicare Levy Surcharge

Calculating your potential Medicare Levy Surcharge is straightforward once you know your income tier. A Medicare Levy Surcharge calculator works by comparing your taxable income against the thresholds and applying the appropriate percentage to your total income.

Here's how to estimate your MLS liability:

1. Determine your taxable income for the financial year (including reportable fringe benefits, super contributions, and investment losses)
2. Check which income tier you fall into based on the table above
3. Multiply your total income by the corresponding MLS rate

For instance, a single person earning $120,000 in 2025-26 falls into Tier 2 and would pay:

$120,000 × 1.25% = $1,500 Medicare Levy Surcharge

This surcharge is calculated when you lodge your tax return. If you want to understand how this affects your overall take-home pay, our comprehensive calculator can show you exactly how much you'll receive after all taxes, levies, and surcharges are deducted.

Remember that the MLS is calculated on your income for the full financial year. If you take out private hospital cover partway through the year, you'll only avoid the surcharge for the days you were covered. This is why it's worth considering your insurance options before the financial year begins if you're approaching the income thresholds.

How to Avoid the Medicare Levy Surcharge

The simplest and most effective way to avoid paying the Medicare Levy Surcharge is to maintain an appropriate level of private hospital cover throughout the financial year. But what counts as "appropriate"? According to the Australian Taxation Office (ATO), your policy must be issued by a registered Australian health insurer and provide hospital cover with an excess of no more than $750 for singles or $1,500 for families/couples.

It's worth noting that extras-only policies (covering dental, optical, physiotherapy, etc.) do not exempt you from the MLS. You need genuine hospital cover that includes accommodation and medical treatment in a hospital setting. Many Australians mistakenly believe their extras policy protects them from the surcharge, only to discover the extra tax bill at EOFY.

Before taking out hospital cover to avoid the MLS, consider these factors:

• Premium costs vs. MLS savings: Compare your annual MLS liability with the cost of basic hospital cover premiums
• Lifetime Health Cover loading: If you're over 31 and haven't had hospital cover, you may pay an additional 2% loading for every year you're over 30
• Waiting periods: Most hospital policies have waiting periods for pre-existing conditions and pregnancy
• Excess and coverage limits: Understand what you're actually covered for and what out-of-pocket costs you might face

For many higher-income earners, taking out basic hospital cover is actually cheaper than paying the MLS. Plus, you get the benefit of private healthcare options when you need them. It's a financial win-win that also gives you more control over your medical care.

Medicare Levy Surcharge vs. Private Health Insurance Rebate

While the Medicare Levy Surcharge penalizes higher-income earners without hospital cover, the Private Health Insurance Rebate does the opposite—it provides a government subsidy to help with the cost of your premiums. Understanding both can help you make an informed decision about whether private health insurance makes financial sense for your situation.

The rebate is income-tested and decreases as your earnings increase. For the 2025-26 financial year, singles earning above $151,000 and families above $302,000 receive no rebate at all—the same thresholds where the MLS peaks at 1.5%. This means if you're in Tier 3, you pay the maximum surcharge and receive zero rebate on any insurance you do purchase.

However, for those in Tier 1 and Tier 2, the combination of avoiding the MLS and receiving a partial rebate often makes private hospital cover financially attractive. You can claim the rebate as a reduction in your premiums throughout the year or as a refundable tax offset when you lodge your return.

If you're also dealing with HECS-HELP repayments or considering salary sacrifice arrangements, these can affect your taxable income and potentially your MLS tier. Structuring your income efficiently could drop you into a lower tier or even below the threshold entirely, saving you thousands in combined taxes and surcharges.

Understanding Your Complete Tax Position

The Medicare Levy Surcharge is just one piece of Australia's complex tax puzzle. To get a complete picture of your tax obligations, you need to consider how it interacts with other levies and obligations. The standard Medicare Levy is 2% of your taxable income for most Australians. On top of that, the MLS can add another 1% to 1.5% if you don't have hospital cover and earn above the thresholds.

Additionally, your superannuation contributions—both employer and personal—can affect your income calculations for MLS purposes. Reportable employer super contributions and deductible personal contributions are added back to your income when determining your MLS tier, so even salary sacrificing into super won't necessarily reduce your surcharge liability.

If you're a high-income earner, you might also be subject to the Division 293 tax, which adds an extra 15% tax on concessional super contributions for those earning over $250,000. Understanding all these moving parts is essential for effective tax planning and maximizing your after-tax income.

Conclusion

The Medicare Levy Surcharge is an important consideration for any Australian earning above the income thresholds. While nobody enjoys paying extra tax, understanding how the MLS works gives you the power to make informed decisions about your health insurance and potentially save hundreds or thousands of dollars each year.

For the 2025-26 financial year, take the time to assess where your income falls in relation to the MLS tiers. If you're earning above $97,000 (or $194,000 as a family) and don't have private hospital cover, getting a quote for basic hospital insurance could be one of the smartest financial moves you make this year. Not only will you avoid the surcharge, but you'll also gain access to private healthcare options when you need them.
