Medicare Levy Low-Income Reduction Explained (Australia 2025-26)

General information only. Speak with a registered tax agent for advice.

Many Australians assume the Medicare levy is always a flat 2% of taxable income. That is not true for low-income earners.

The ATO says low-income individuals can pay a reduced Medicare levy or no Medicare levy at all, depending on their income and circumstances. This is separate from the Medicare Levy Surcharge (MLS), which applies under a different test.

The core rule

For the 2025-26 income year, the Medicare levy does not simply switch on in full at one exact dollar figure.

Instead, there is:

• a full exemption threshold
• a shade-in range
• then the normal 2% levy once income is high enough

That means someone just above the low-income threshold may pay only a partial levy, not the full 2%.

Why the shade-in range matters

This is the part people often miss.

If you are inside the shade-in range, the levy increases gradually until it reaches the ordinary 2% amount. That prevents a sharp cliff where earning one extra dollar would suddenly trigger the full levy.

This matters most for:

• part-time workers
• students with mixed work patterns across the year
• retirees with modest taxable income
• people comparing whether extra income will materially change take-home pay

Low-income reduction is not the same as MLS

The Medicare Levy Surcharge is a different rule.

The ATO applies MLS to higher-income taxpayers who do not have an appropriate level of private patient hospital cover. A person can be below the low-income Medicare levy thresholds and pay no levy, while someone else on much higher income may still face MLS on top of the ordinary levy.

Do not mix the two tests together.

Why calculator outputs can differ

Some general tax calculators model the standard 2% levy but do not fully model the low-income Medicare levy reduction.

That is why low-income earners can see a rough estimate that looks too high. If you are near the levy thresholds, it is worth checking the dedicated Medicare levy settings rather than assuming the simple 2% rule is the final answer.

Practical checklist

• Check whether your taxable income falls under the low-income threshold or shade-in range
• Do not confuse the ordinary Medicare levy with MLS
• Recheck the result if your income is close to the threshold
• Review whether family or seniors-and-pensioners thresholds apply instead of the standard single threshold
• Use a levy-specific calculator if the levy outcome materially changes your refund or tax bill

Run this if the 2% levy estimate looks wrong

If the risk is “a rough tax estimate is charging me the full Medicare levy even though my income is low”, check the levy separately before trusting the number.

• Use the Medicare Levy & MLS Calculator to isolate the levy and surcharge position and see whether you are near the thresholds.
• Use the Income Tax Calculator if you want the wider annual tax view after you have checked whether a levy reduction may apply.
