$2,400 Extra Tax? The Medicare Levy Surcharge Explained

▶

An Australian single earning $160,000 with no hospital cover will hand the ATO an extra $2,400 in Medicare Levy Surcharge in one year alone—on top of the standard Medicare levy—because they’ve crossed into the 1.5% MLS bracket.

The number that matters

1.5% — top Medicare Levy Surcharge rate on income above the highest threshold for Australians without eligible hospital cover (ATO, 2025–26 thresholds).

How it quietly costs you

Mechanism: “Hidden” extra tax once your income crosses the MLS thresholds and you don’t have eligible private hospital cover.

• The Medicare Levy Surcharge (MLS) is an additional tax of 1%, 1.25% or 1.5% on top of the standard 2% Medicare levy if you are a higher‑income taxpayer without appropriate private hospital cover.
• For 2025–26, the ATO’s MLS thresholds are:
• Singles
• Base tier: $101,000 or less – 0% MLS
• Tier 1: $101,001–$118,000 – 1% MLS
• Tier 2: $118,001–$158,000 – 1.25% MLS
• Tier 3: $158,001 or more – 1.5% MLS
• Families/couples (combined income)
• Base tier: $202,000 or less – 0% MLS
• Tier 1: $202,001–$236,000 – 1% MLS
• Tier 2: $236,001–$316,000 – 1.25% MLS
• Tier 3: $316,001 or more – 1.5% MLS
• Family thresholds increase by $1,500 for each MLS‑dependent child after the first.

When it hits you:

• You may have to pay MLS for any period during the income year where both apply:

1. your income for MLS purposes is above the relevant threshold, and
2. you and your dependants do not have appropriate private hospital cover.

• To be exempt, you must hold eligible hospital cover (extras‑only does not count) for the entire income year, with a maximum excess of $750 for singles or $1,500 for couples/families.

Impact – concrete examples (2025–26):

Using ATO thresholds and MLS rates:

• Single, income $110,000, no hospital cover (Tier 1, 1% MLS):
• Extra tax = 1% of $110,000 = $1,100 for that year.
• Single, income $150,000, no hospital cover (Tier 2, 1.25% MLS):
• Extra tax = 1.25% of $150,000 = $1,875.
• Single, income $180,000, no hospital cover (Tier 3, 1.5% MLS):
• Extra tax = 1.5% of $180,000 = $2,700.
• Family, combined income $230,000, no cover (Tier 1, 1% MLS):
• Extra tax = 1% of $230,000 = $2,300.
• Family, combined income $330,000, no cover (Tier 3, 1.5% MLS):
• Extra tax = 1.5% of $330,000 = $4,950.

Old vs better (what you “think” vs optimised):

• Many higher‑income earners assume they “just pay the 2% Medicare levy.” In reality, if they cross the thresholds without cover, their effective health‑related levy becomes 3%–3.5% of income (2% levy + 1–1.5% MLS).
• Meanwhile, entry‑level hospital cover that satisfies the MLS test is often priced well below the annual surcharge cost, meaning many people could pay hundreds or thousands less per year by holding a compliant policy instead of paying MLS (specific premiums vary by insurer and state; the key is the 1%–1.5% of income benchmark).

The second, compounding trap

Mechanism: Misunderstanding what “counts” as cover and how income is measured, leading to years of unnecessary MLS.

There are two big traps:

1. Wrong type of cover – extras‑only doesn’t count

• To avoid MLS you must have approved private hospital cover; extras‑only policies do not qualify.
• The cover must have an excess no higher than $750 (single) or $1,500 (family) to count for MLS purposes.
• Someone with only dental/optical extras on a high income can still be charged the full 1%–1.5% MLS.

2. Income for MLS purposes is broader than “taxable income”

• The ATO calculates MLS on income for MLS purposes, which generally includes:
• taxable income
• reportable fringe benefits
• total net investment losses
• some super contributions (reportable).
• This means a person who thinks their “salary” is below $101,000 could still be pushed into MLS territory by bonuses, investment income, or salary‑sacrifice arrangements.

Long‑run cost of inaction – concrete modelling:

Assume no hospital cover, income grows modestly at ~3% p.a., and you remain above the thresholds for 10–20 years. MLS is applied to the full income each year:

• Single, starting income $120,000 (Tier 2 band initially, 1.25% MLS):
• Year 1 MLS = 1.25% × $120,000 = $1,500
• Year 10 income (approx): (120,000 × 1.03^9 ≈ 156,000) → MLS ≈ 1.25% × $156,000 ≈ $1,950
• Over 10 years, simple sum (ignoring compounding) ≈ $17,250 in MLS.
• Single, starting income $160,000 (Tier 3, 1.5% MLS):
• Year 1 MLS = 1.5% × $160,000 = $2,400
• Year 10 income (approx): (160,000 × 1.03^9 ≈ 208,000) → MLS ≈ 1.5% × $208,000 ≈ $3,120
• Rough 10‑year MLS burden ≈ $26,000–$27,000.
• Family, starting combined income $230,000 (Tier 1, 1% MLS):
• Year 1 MLS = 1% × $230,000 = $2,300
• Year 10 income (approx): (230,000 × 1.03^9 ≈ 299,000) → MLS ≈ $2,990
• 10‑year MLS total ≈ $26,000–$27,000.

These are simple projections using ATO’s percentage bands; real outcomes will vary with income growth, time spent in each tier, and rule changes, but the direction is clear: small annual “extra tax” turns into tens of thousands over a decade.

What this looks like in practice

Persona:

• Name: Alex
• Age: 34
• Job: IT project manager in Sydney
• Income (2025–26): $145,000 salary + $5,000 bonus (income for MLS purposes: $150,000)
• Family status: Single, no dependants
• Super balance: $120,000 (not central to MLS, but relevant to long‑term wealth)
• Years to retirement: ~33 years
• Health cover: Extras‑only policy (dental/physio) – no hospital cover
• Tax year: 2025–26; income places Alex in Tier 2 (1.25% MLS) as a single over $118,000 without cover.

Discovery 1 – “I’m paying more in MLS than a basic hospital policy would cost”

• At $150,000 income, Alex’s MLS is 1.25% × $150,000 = $1,875 for the year if they have no eligible hospital cover.
• Entry‑level, MLS‑compliant hospital cover (with excess ≤$750) often costs well under $1,875 per year for a 34‑year‑old single (exact amounts vary by state and insurer; the key benchmark is the 1.25% of income = $1,875 “extra tax” Alex is currently paying).
• Compared with doing nothing, Alex could potentially swap $1,875 of tax for a similar or lower spend on actual hospital cover, effectively redirecting money from the ATO to an insurance policy that provides real benefits.

Discovery 2 – “My extras‑only cover doesn’t save me from MLS”

• Alex assumed their extras‑only health policy meant “I’ve got private health, so I’m sweet.”
• But the ATO and major tax educators are explicit: extras‑only cover does not qualify as “appropriate private patient hospital cover” for MLS purposes.
• Because Alex has no approved hospital cover, they are charged the full 1.25% MLS, meaning an unexpected $1,875 extra tax for 2025–26, despite already paying for private health insurance.

Discovery 3 – “My ‘income for MLS purposes’ is higher than my salary”

• Alex thought their “income” was $145,000, just under the mental cutoff they had in mind.
• The ATO, however, uses income for MLS purposes, which includes taxable income plus items like bonuses, reportable fringe benefits, investment losses and some super contributions.
• When Alex includes their $5,000 bonus, their MLS income is $150,000, firmly in Tier 2 (1.25%), leading to the $1,875 MLS bill. If Alex had stayed in Tier 1 (1% MLS) at $110,000, the MLS would have been only $1,100, a $775 per‑year difference in extra tax due solely to moving up a tier.

The full cost of doing nothing

Headline number:

For Alex, if they stay on roughly today’s path—no compliant hospital cover, income starting at $150,000 and growing at ~3% p.a., always above the MLS thresholds—the combined impact of Problem 1 (being in MLS at all) and Problem 2 (misunderstanding cover and income rules, leading to no action) is around $70,000–$80,000 in extra tax over their remaining 33‑year career, in today’s dollars.

Modelling basis (illustrative, using ATO MLS rates and thresholds):

• Starting point:
• 2025–26 income for MLS = $150,000, no hospital cover.
• MLS rate = 1.25%, so Year 1 MLS = $1,875.
• Income growth assumption: 3% nominal per year.
• MLS status assumption:
• Alex remains at least in Tier 2 (1.25%) for most of their career; for simplicity, assume an average MLS rate of 1.25% over 33 years (real life may move between tiers).
• Approximate lifetime MLS paid:
• Using a rough average income over the period of $180,000 (as salary grows from $150k into the $200k+ range) × 1.25% MLS = $2,250 average MLS per year.
• Over 33 years, that is $2,250 × 33 ≈ $74,250 in extra tax.

This is a stylised estimate based on ATO’s published MLS percentages; actual outcomes depend on income volatility, time spent in each tier, and future policy changes, but it illustrates that misunderstanding and inaction can easily cost tens of thousands of dollars over a career.

What to do about it

Each of these can be done in under 30 minutes using free tools or official guidance.

1. Check whether you’re already in MLS territory

1. Action: Calculate your income for MLS purposes and identify your MLS tier.
2. Tool/portal:

• ATO guidance on “Medicare levy surcharge – income thresholds and rates” and “M2 Medicare levy surcharge” instructions for the Individual tax return.

3. Steps:

1. Log in to myGov → ATO Online and open your latest Notice of Assessment; note your taxable income and any reportable fringe benefits, investment losses, and reportable super contributions.
2. Use the ATO’s MLS instructions (Question M2) to calculate your income for MLS purposes, adding those components.
3. Compare the result to the 2025–26 MLS thresholds:

• Single: $101,000 / $118,000 / $158,000
• Family: $202,000 / $236,000 / $316,000 to see if you are at 0%, 1%, 1.25% or 1.5% MLS.

4. What “good” looks like:

• You can clearly state “My income for MLS is $X, which puts me in [Base / Tier 1 / Tier 2 / Tier 3], so my MLS rate is Y%.”
• If Y > 0 and you don’t have qualifying hospital cover, you know exactly how much extra tax you’re on the hook for: (Y% × X).

2. Confirm whether your existing health cover actually exempts you

1. Action: Verify if your current health policy counts as “appropriate private hospital cover” for MLS.
2. Tool/portal:

• Your insurer’s online portal/policy schedule, and official guidance from ATO and Private Healthcare Australia on MLS requirements.

3. Steps:

1. Log in to your health insurer’s portal and download your policy certificate; check if it includes hospital cover, and note the excess.
2. Check the MLS criteria: an approved hospital policy with a front‑end deductible/excess of $750 or less (single) or $1,500 or less (family) is required; extras‑only or higher excess policies don’t qualify.
3. If your cover is extras‑only or exceeds the allowed excess, call or chat with your insurer and ask: “Can you show me which of your products is MLS‑compliant hospital cover for my situation?”

4. What “good” looks like:

• Your policy explicitly includes hospital cover and the excess is ≤ $750 (single) or ≤ $1,500 (family), giving you full MLS exemption for the days covered in the financial year.

3. Compare the MLS you’d pay vs the cost of MLS‑compliant cover

1. Action: Decide whether to pay MLS or pay for hospital cover by comparing dollars side‑by‑side.
2. Tool/portal:

• ATO MLS thresholds and rates for your current year, plus at least one fund’s online quote for basic hospital cover that meets the MLS conditions (any registered Australian health fund).

3. Steps:

1. From Move 1, calculate your annual MLS: MLS rate (1–1.5%) × income for MLS purposes. Write that number down.
2. Use a major fund’s website to get a quote for basic/entry‑level hospital cover (single or family), ensuring it is MLS‑compliant (excess ≤$750/1,500).
3. Compare: if the annual premium for that policy is less than or similar to your annual MLS, consider switching from “paying tax for nothing” to “paying for cover and avoiding MLS.”

4. What “good” looks like:

• For many higher‑income earners, the annual hospital premium is lower than or comparable to the MLS bill; paying for cover instead of tax gives you both MLS relief and actual hospital benefits, which is generally a better value proposition than paying 1%–1.5% of your income in extra tax.

A myth worth clearing up

Myth: “I already have private health (extras), so I don’t pay the Medicare Levy Surcharge.”

Fact: The MLS only recognises appropriate private patient hospital cover, not extras‑only policies.

• To avoid MLS, your policy must include hospital cover with an excess no more than $750 for singles or $1,500 for couples/families.
