If you’ve ever glanced at your tax return and wondered why you’re paying more than you expected, the medicare levy surcharge might be the culprit. It’s one of those tax obligations that catches plenty of Australians off guard, particularly higher earners who don’t hold private hospital cover. So let’s break it down clearly: what the medicare levy surcharge actually is, who it applies to, and what you can do about it.

The Medicare Levy vs. the Medicare Levy Surcharge

Before we dive in, it’s worth clearing up a common point of confusion. There are two separate charges here, and people often mix them up.

The Medicare Levy

A flat 2% charge on your taxable income that almost all Australian taxpayers pay. It funds Australia’s public health system, Medicare, your ticket to bulk-billed GP visits, public hospital care, and a range of subsidised health services.

The Medicare Levy Surcharge (MLS)

An additional tax on top of the Medicare Levy, and it only applies to higher-income earners who don’t hold an appropriate level of private patient hospital cover. Think of it as the government’s way of nudging wealthier Australians towards the private health system to take pressure off the public one.

Who Has to Pay the Medicare Levy Surcharge?

The medicare levy surcharge applies to Australian taxpayers (individuals, families, and certain dependants) whose income exceeds a set threshold and who don’t hold qualifying private hospital cover for the full income year.

For the 2024–25 financial year, the income thresholds were:

• Singles: Taxable income over $93,000
• Families: Combined taxable income over $186,000

For families, the threshold increases by $1,500 for each dependent child after the first.

It’s also important to note what counts as “income” for MLS purposes. The ATO doesn’t just look at your salary. They include your taxable income plus any total net investment losses, reportable fringe benefits, and reportable employer super contributions. This broader definition catches more people than you might expect.

How Much Is the Medicare Levy Surcharge?

The MLS isn’t a flat fee. It’s calculated as a percentage of your income, and the rate increases with your earnings. There are three tiers:

To put that in real terms: if you’re a single person earning $110,000 and you don’t have private hospital cover, you’d be paying an additional 1.25% on top of your standard Medicare Levy – that’s $1,375 on top of your existing $2,200 Medicare Levy. All up, that’s $3,575 in Medicare-related charges for the year.

How Does It Affect Your Tax Return?

The medicare levy surcharge is calculated when you lodge your tax return. You’ll be asked whether you held private hospital cover for the full year, and if you didn’t (or if you only held it for part of the year) the ATO will calculate the surcharge based on the number of days you were without cover.

This means the MLS is applied pro-rata. If you had private hospital cover for six months and not for the other six, you’ll only be charged the surcharge for the period you were uninsured. It pays to keep records of your cover dates and any certificates your insurer provides.

The surcharge is automatically included in your tax assessment, so there’s no separate form to lodge. However, it can come as a nasty surprise if you weren’t expecting it, particularly if you’ve recently had a pay rise that pushed you over a threshold.

What Counts as “Qualifying” Private Hospital Cover?

Not just any private health insurance policy will get you off the hook. To avoid the medicare levy surcharge, you need to hold private patient hospital cover, and it must meet a minimum standard set by the government.

Specifically, the policy must:

• Be with a registered Australian health insurer
• Cover hospital treatment as a private patient
• Have an excess no greater than $750 for singles or $1,500 for families

Extras-only policies (like dental and optical cover) do not count. Overseas visitor health cover generally doesn’t qualify either. If you’re unsure whether your current policy meets the standard, contact your health insurer directly, they should be able to confirm.

Does It Make Financial Sense to Take Out Private Hospital Cover?

This is the big question most people ask once they discover they’re liable for the medicare levy surcharge. And honestly, the maths often stacks up in favour of getting covered.

Basic hospital cover from a registered insurer can cost as little as $1,000–$1,500 per year for a single person, sometimes less, depending on your age and the fund. If you’re in Tier 1 and earning $95,000, your MLS liability would be $950 per year. In that case, the MLS and the cost of cover are roughly comparable, and you’d need to weigh up the other benefits of holding cover.

However, once you’re in Tier 2 or Tier 3, the calculus becomes clearer. A 1.25% or 1.5% surcharge on a six-figure income will almost always exceed the cost of a basic hospital policy, meaning you’d be paying more tax for less benefit than if you simply took out cover.

There’s also the Lifetime Health Cover (LHC) loading to consider. If you’re 31 or older and don’t hold hospital cover, you’ll pay a 2% loading on your private hospital premiums for every year you were uninsured after turning 30 (up to a maximum of 70%). The longer you wait, the more expensive it gets to join later in life.

Key Takeaways

The medicare levy surcharge is a tax that affects higher-income Australians without private hospital cover, and it can add up to thousands of dollars a year. Here’s a quick summary:

• It’s separate from the standard 2% Medicare Levy
• It applies if your income exceeds $93,000 (singles) or $186,000 (families)
• The rate is 1.0%, 1.25%, or 1.5% depending on your income tier
• It can be avoided by holding an eligible private hospital insurance policy with a compliant excess
• Extras-only cover does not exempt you from the surcharge

If you’re approaching these income thresholds or you’ve recently had a pay rise, it’s worth reviewing your private health insurance situation before the end of the financial year. A quick conversation with a financial adviser or your health insurer could save you a meaningful chunk of change come tax time.
