Australia’s Medicare levy surcharge is easy to miss because it is not the same as the ordinary Medicare levy. Most taxpayers pay the 2 percent Medicare levy through the income tax system. The surcharge is extra, and it is aimed at higher-income people who do not hold suitable private hospital cover. For the 2026-27 income year the first surcharge threshold is $105,000 for singles and $210,000 for families, so a pay rise, a bonus or investment income can turn a private health decision into a tax calculation.
The surcharge does not pay for a policy. It is an additional tax on income. That is why the comparison is not “cover versus no cover” in the abstract. The practical question is whether the extra tax you would pay without hospital cover is close to, below or above the premium you would pay for a complying policy. The answer changes by income, family status and state, but the starting arithmetic is the same for everyone.
The 2026-27 MLS thresholds
The Australian Taxation Office raised the private health income thresholds from 1 July 2026. These are the Medicare levy surcharge tiers for the 2026-27 income year.
| Tier | Singles income for MLS purposes | Families income for MLS purposes | Surcharge rate |
|---|---|---|---|
| Base tier | $105,000 or less | $210,000 or less | 0% |
| Tier 1 | $105,001 to $123,000 | $210,001 to $246,000 | 1% |
| Tier 2 | $123,001 to $164,000 | $246,001 to $328,000 | 1.25% |
| Tier 3 | $164,001 or more | $328,001 or more | 1.5% |
For families, the threshold increases by $1,500 for each dependent child after the first. A couple with three dependent children starts with the $210,000 family base, then adds $3,000 because the second and third children each lift the line by $1,500. Their base tier therefore reaches $213,000 before the 1 percent surcharge starts.
The family threshold applies to couples, including de facto couples, and to single parents with dependent children. The ATO looks at income for surcharge purposes, not only taxable income, so the figure can be higher than the salary line on your payment summary.
How the surcharge is calculated
The rate applies to your income for MLS purposes, not only the slice above the threshold. That makes the first dollar over a threshold expensive. A single person on $105,000 owes no Medicare levy surcharge if they do not have suitable hospital cover. At $105,001 they are in tier 1, so the surcharge is about $1,050 for the year.
Here are three single-person examples using the 2026-27 bands.
| Income for MLS purposes | MLS tier without hospital cover | Approximate surcharge |
|---|---|---|
| $110,000 | Tier 1 at 1% | $1,100 |
| $135,000 | Tier 2 at 1.25% | $1,687.50 |
| $180,000 | Tier 3 at 1.5% | $2,700 |
For a couple, the same rates apply to family income. A household on $230,000 with no dependent children is in tier 1, so the surcharge is $2,300. At $270,000 it is tier 2, or $3,375. At $350,000 it is tier 3, or $5,250.
You can use the Australia salary and tax calculator to estimate income tax and the ordinary Medicare levy first, then add the surcharge manually if your situation lands in one of these tiers. For premium comparisons, the budget calculator is useful because private hospital cover is a recurring annual cost, not a one-off tax bill.
What counts as income for MLS purposes
Income for surcharge purposes is broader than taxable income. The ATO starts with taxable income, then adds items that are meant to stop people moving income out of the measure. These include reportable fringe benefits, reportable employer super contributions, net financial investment losses, net rental property losses and some exempt foreign employment income.
That matters when the threshold is close. Salary sacrifice into super can reduce taxable income, but reportable employer super contributions may be added back for the MLS test. A negatively geared property can reduce taxable income, but the net rental loss is also added back. The surcharge therefore catches the broader economic income that sits behind the tax return.
The ATO also has specific rules for lump sums, spouse income and periods when you had hospital cover for only part of the year. If you held a complying policy for six months and were uninsured for six months, the surcharge can apply only to the uninsured days, subject to the rest of the test.
What hospital cover avoids the surcharge
Extras cover by itself does not remove the Medicare levy surcharge. Ambulance-only cover does not remove it either. You need complying private patient hospital cover from a registered health insurer.
For 2026, a policy can still count if it carries an excess of up to $750 for a single person or $1,500 for couples and families. If the excess is above the allowed level, the policy may not protect you from the surcharge even though it is hospital insurance in everyday language. This is one reason a low-premium policy needs a careful read before you count on it for tax purposes.
The cover must be held for you, your spouse if you have one, and your dependent children if the family rules apply. If one member of the family is not covered, the family can still have an MLS issue.
The rebate and Lifetime Health Cover are separate
Three private health rules often get bundled together, but they do different jobs.
The Medicare levy surcharge is a tax charge for higher-income people without suitable hospital cover. The private health insurance rebate is a government contribution toward eligible premiums, and it also uses income tiers. Lifetime Health Cover is a loading on hospital premiums for people who first take out cover after their Lifetime Health Cover base day, usually 1 July after turning 31. The loading is 2 percent for each year over 30, capped at 70 percent, and can be removed after 10 continuous years of hospital cover.
The decisions interact. A 34-year-old single person above the MLS threshold may face a surcharge if uninsured and a Lifetime Health Cover loading if they wait longer to buy hospital cover. Someone below the threshold may still care about Lifetime Health Cover, but the surcharge itself is not the reason.
A practical decision process
Start by estimating your income for MLS purposes, not only your salary. Add expected investment losses, reportable super contributions and fringe benefits if they apply. Then compare that figure with the 2026-27 tier table.
Next, work out the annual surcharge you would pay without hospital cover. If you are single on $118,000, the tax cost is about $1,180. If the cheapest suitable hospital policy costs less than that after any rebate, the tax arithmetic points toward cover, although policy value and personal health needs still matter. If the premium is much higher than the surcharge, the tax saving alone does not justify it.
Finally, check the timing. The surcharge is based on days without suitable cover during the income year, so buying a policy late in June does not erase the whole year’s exposure. It may still reduce the number of uncovered days, but it is not the same as being covered from 1 July.
These figures are for orientation, not tax or health insurance advice. The right policy decision depends on the hospitals, exclusions, waiting periods and excesses in the product you are comparing.
FAQ
What is the Medicare levy surcharge threshold for 2026-27? For singles, the surcharge starts once income for MLS purposes is above $105,000. For families, it starts above $210,000, plus $1,500 for each dependent child after the first.
Is the Medicare levy surcharge the same as the Medicare levy? No. The ordinary Medicare levy is generally 2 percent and applies broadly through the income tax system. The surcharge is extra and applies only when your income is above the relevant threshold and you do not have suitable private hospital cover.
Does extras cover avoid the surcharge? No. Extras-only cover does not count. You need complying private patient hospital cover, with the excess no higher than the allowed single or family limit.
Is the surcharge charged only on income above the threshold? No. Once you are in a tier, the rate applies to your income for MLS purposes. A single person on $110,000 without suitable cover faces about $1,100 of surcharge, not 1 percent of only the amount above $105,000.
Can a family threshold be higher than $210,000? Yes. The family threshold rises by $1,500 for each dependent child after the first. With three dependent children, the base threshold becomes $213,000.
