Medicare Levy Surcharge: The Tax That Buys You Nothing

A single professional earning $130,000 without hospital cover will hand the ATO an extra $1,625 this year. Not for faster treatment, not for a private room, not for anything. That is the Medicare levy surcharge: the only line on your notice of assessment where roughly the same money, pointed at a qualifying insurance policy instead, would have bought you an actual benefit.

Every July we see the same surprise on tax returns: clients who did not realise they had crossed the income threshold, or assumed their extras cover protected them, or did not know their spouse's income counted. This guide explains what the surcharge is, the current rates and thresholds, how the family and dependant rules work, and the simple comparison we recommend every client above the threshold runs.

What Is the Medicare Levy Surcharge?

The surcharge exists as a policy lever. The government wants higher earners to take out private hospital insurance and ease pressure on the public system, so it makes not having cover cost real money. The ATO's Medicare levy surcharge guidance sets out when it applies and at what rates.

Here is the part that matters for planning: the surcharge is calculated on your whole income for MLS purposes, not just the amount above the threshold. Earn one dollar over a tier boundary and the higher rate applies to every dollar you earned. That cliff effect is why a small salary movement in June can create a four-figure tax difference, and why the surcharge belongs in any serious tax planning conversation.

What Is the Difference Between the Medicare Levy and the Medicare Levy Surcharge?

The two are confused constantly, including by people who have been paying both for years. The 2% Medicare levy is close to universal; low-income earners get a reduction or exemption, but private health insurance has no effect on it. The surcharge is the optional extra. It is the one you control.

So a single person on $170,000 with no hospital cover pays both: $3,400 in Medicare levy plus $2,550 in surcharge for 2026–27, a combined $5,950. With qualifying hospital cover, the second amount disappears. You can test your own position with the ATO's Medicare levy calculator.

What Are the Medicare Levy Surcharge Thresholds and Rates?

Two sets of thresholds matter right now. The return you lodge this tax season covers 2025–26, while any decision you make about cover today plays out against the 2026–27 thresholds. Both tables below come from the ATO's income thresholds and rates page.

2025–26 income year (the return you lodge now)

2026–27 income year (the year you are in now)

Remember the cliff. A single person on exactly $105,000 in 2026–27 pays no surcharge. On $105,001, the surcharge is roughly $1,050, because 1% applies to the whole amount. If your income sits near a boundary, timing a deductible expense or a concessional super contribution before 30 June can matter far more than it first appears.

What Income Counts for Medicare Levy Surcharge Purposes?

This definition is where most of the surprises come from. Negative gearing reduces your taxable income, but the loss is added straight back for surcharge purposes; a reader weighing up property investment should also see our analysis of the proposed negative gearing changes. Salary-sacrificed super does the same, which surprises clients using contributions as their main tax lever, including those with a self managed super fund.

In our experience working with professional services clients, reportable fringe benefits are the most common blind spot. One Melbourne professional we act for had taxable income of $100,000 for 2025–26 and assumed they sat safely under the singles threshold of $101,000. A novated lease added $14,000 of reportable fringe benefits, lifting MLS income to $114,000 and triggering a 1% surcharge of $1,140. Nothing about the lease was wrong; the client simply had not been told it counted.

Who Counts as Family and Dependants for the Surcharge?

The family rules in the ATO's family and dependants guidance catch people in three ways. First, combined income: two moderate salaries of $110,000 each make a $220,000 family, over the 2026–27 threshold, even though neither person would face the surcharge alone. Second, coverage is all or nothing: a couple where one partner holds hospital cover and the other does not can still both be liable. Third, dependants count. A 22-year-old at university full time is still a dependant, and if they are not covered by the family policy or their own, the surcharge can apply to the parents.

A spouse means anyone you live with on a genuine domestic basis as a couple, regardless of sex, not just a married partner. Biological, adopted and step children all count as dependants; foster children do not. Medical and dental families should note these rules interact with income structures we cover in how doctors are taxed in Australia, and they are a standing item in our work for doctors, dentists and health practices.

The Dollar Maths: Surcharge vs Hospital Cover

This is the comparison we recommend every client above the threshold runs, and it is the one thing the insurer-written guides on page one of Google never show plainly. The question is not whether private health insurance is good value in the abstract. The question is: given that you will pay one of these two amounts either way, which one buys you something?

Take a single consultant on $130,000 of MLS income in 2026–27. Without hospital cover, the surcharge is 1.25% of $130,000, which is $1,625. That $1,625 buys nothing. No cover, no extras, no waiting-list advantage, no benefit of any kind. It is simply additional tax. A basic qualifying hospital policy for a single person can cost a broadly comparable annual amount. For roughly the same outlay, the policy buys actual hospital cover, removes the surcharge entirely, and stops a second cost quietly accruing in the background.

Calculated from ATO 2026–27 MLS rates and thresholds. The surcharge applies to whole MLS income, not the excess over the threshold.

The background cost is Lifetime Health Cover loading. Under the Lifetime Health Cover rules, taking out hospital cover after the 1 July following your 31st birthday adds a 2% loading to your premium for every year of delay, up to a maximum of 70%, and the loading only clears after 10 years of continuous cover. Someone who first takes cover at 40 pays 20% more for the same policy for a decade. Delaying the decision is not free even in the years you sit under the surcharge threshold.

One important boundary: we are tax advisors, not insurance brokers. Whether a particular policy suits your health needs is a decision to make on the policy's merits, and the government's privatehealth.gov.au comparison service lets you compare every registered policy without a sales filter. Our role is the tax side: telling you exactly what the surcharge will cost you this year, so you can compare that number against a real quote rather than a guess.

How Do You Avoid the Medicare Levy Surcharge?

The ATO's definition of appropriate cover trips up two groups. The first holds extras-only cover for dental, optical or physiotherapy and assumes it counts. It does not; only hospital cover qualifies. The second holds hospital cover with a high excess to keep premiums down, not realising that an excess above $750 (singles) or $1,500 (couples and families) disqualifies the policy for surcharge purposes.

Timing is the other trap. The surcharge is applied for each day you did not hold appropriate cover, per the ATO's guidance on paying the surcharge. Taking out a policy in March does not clear the year; you remain liable for the July-to-March days. If you expect to be over the threshold in 2026–27, cover needs to be in place from 1 July, and it needs to stay in place. Cancelling for a few months while travelling creates liable days and can restart Lifetime Health Cover consequences. We flag these dates alongside the lodgement calendar in our guide to key ATO due dates.

If your income is genuinely borderline, deductions and super contributions can also keep you under the threshold, but that analysis needs your full facts. A CPA accountant can model both levers together, and for business owners the answer often interacts with how you draw income from the business, which is core small business accounting territory.

Key Takeaways

• The surcharge starts at $101,001 (singles) and $202,001 (families) for 2025–26, and $105,001 and $210,001 for 2026–27, at 1% to 1.5% of your whole MLS income.
• Check your income for MLS purposes, not just taxable income: fringe benefits, reportable super and investment losses all count.
• Only hospital cover with an excess of $750 or less (singles) or $1,500 or less (couples and families) avoids the surcharge. Extras cover does nothing.
• Every family member, including student children up to 24, must be covered or the surcharge can still apply.
• If you will pay either way, compare the two numbers: the surcharge buys nothing, while cover at a similar cost buys cover and stops Lifetime Health Cover loading accruing.
