Medicare Levy and MLS 2026-27: The Quiet Drag on Your Borrowing Power

For most Australian employees, the Medicare Levy and Medicare Levy Surcharge (MLS) are deducted from salary before take-home pay lands in a bank account, which means they are also deducted from the net income figure a lender uses when calculating your maximum loan quote. The standard Medicare Levy is 2% of taxable income. The MLS applies on top of that for higher-income earners without an eligible private hospital insurance policy, with single-income thresholds starting at $101,000 in 2025‑26: 1.0% for income between $101,001 and $118,000, 1.25% between $118,001 and $158,000, and 1.5% above $158,000. Together, these can strip between 2% and 3.5% off the gross income a lender feeds into its serviceability model — a model that already tests you at your product rate plus a 3.0 percentage-point APRA buffer. When a mortgage adviser runs your numbers, the income they can use for the assessment is your post-tax, post-levy, post-MLS figure, so a $120,000 salary with no hospital cover does not look like $120,000 to a credit assessor; it looks materially smaller, and the loan quote shrinks with it.

What Is the Medicare Levy and How Is It Calculated in 2026‑27?

The Medicare Levy is a flat 2% charge on taxable income, collected by the Australian Taxation Office as part of the annual income tax assessment. For most employees, it is withheld progressively through the Pay-As-You-Go system, so it reduces net monthly pay before it ever reaches a transaction account. Low-income earners may receive a reduction or full exemption, but for a borrower earning above the phase-in limits, the full 2% applies.

From a loan-quote perspective, the levy is not a discretionary expense. A lender’s serviceability calculator treats it as a compulsory deduction, much like income tax. If you earn $95,000 in taxable income, the Medicare Levy removes approximately $1,900 from your after-tax position each year. When the bank applies its assessment rate — your actual interest rate plus the APRA-mandated 3.0 percentage-point buffer — that $1,900 gap between gross and net income lowers the surplus available for mortgage repayments, compressing the maximum loan amount the system will generate.

What Is the Medicare Levy Surcharge and Who Pays It?

The Medicare Levy Surcharge (MLS) is an additional tax levied on Australian taxpayers who earn above a statutory threshold and do not hold an appropriate private hospital insurance policy. The thresholds and tiered rates for singles in 2025‑26 are:

  • Income up to $101,000: 0%
  • $101,001 to $118,000: 1.0%
  • $118,001 to $158,000: 1.25%
  • $158,001 and above: 1.5%

For families, the base threshold is $202,000, increasing by $1,500 for each dependent child after the first. If a single borrower earns $125,000 and has no hospital cover, the MLS adds 1.25% — roughly $1,562 — on top of the 2% Medicare Levy. The combined deduction climbs to 3.25% of taxable income, or about $4,062 annually. That is income a lender never sees when it calculates your borrowing capacity.

The MLS is avoidable by taking out a basic hospital policy, which is often cheaper than paying the surcharge itself. From a borrowing-capacity standpoint, the calculus is straightforward: holding an eligible policy removes the MLS deduction from your tax return, lifting the net income figure a credit assessor can use. For a borrower sitting just above the $101,000 single threshold, the difference can shift the serviceability outcome enough to move the quoted loan amount by tens of thousands of dollars.

How the Levy and MLS Shrink Your Assessable Income for a Home Loan

Lenders do not assess your mortgage application against your gross salary. They start with gross income, subtract tax, subtract the Medicare Levy, subtract the MLS if applicable, and then subtract declared living expenses and other debt commitments. What remains is the net monthly surplus they test against a sharply elevated assessment rate.

The APRA serviceability buffer of 3.0 percentage points means a loan with an actual rate of 5.5% is assessed as if the rate were 8.5%. The higher the assessment rate, the more sensitive the borrowing-capacity calculation becomes to every dollar of net income. A borrower with a $140,000 taxable income and no private hospital cover faces a 2% Medicare Levy plus a 1.25% MLS, taking $4,550 off the table before the lender even begins the expense analysis. That $4,550 reduction flows directly into a lower maximum repayment capacity, and because the buffer magnifies the effect, the gross loan amount can contract by a multiple of that figure.

This is not a marginal tweak. When a mortgage adviser runs a loan quote on a full-doc PAYG application, the software pulls the MLS flag from the applicant’s tax profile or Medicare eligibility statement. If the flag is present, the net-income input drops, and the quoted borrowing limit drops with it. For couples, the effect can double if both earners are above the single threshold and neither holds hospital cover.

MLS vs Private Health Insurance: Which Choice Protects Your Loan Quote?

The decision to pay the MLS or buy a basic hospital policy is often framed as a tax question. For a borrower preparing a home-loan application, it is better understood as a serviceability question. A basic hospital policy that satisfies the MLS exemption requirements typically costs less than the surcharge for anyone in the 1.25% or 1.5% tiers, but the loan-quote benefit goes further than saving on tax.

When you hold an eligible policy, the MLS line on your notice of assessment disappears. The lender’s calculator uses the higher net income, which feeds directly into the borrowing-capacity model. The effect is most pronounced for borrowers pushing against the APRA debt-to-income (DTI) limit of 6. Since February 2026, banks must keep new lending at DTI ≥ 6 within 20% of each portfolio’s new originations. If your DTI is hovering near that boundary, every dollar of net income matters. Removing a 1.25% or 1.5% MLS deduction can pull your DTI back under the cap and keep your application in the pool that lenders can approve without constraint.

There is a timing consideration too. A hospital policy must be in place before the MLS assessment period ends; it cannot be backdated. If you plan to apply for a home loan in the next six months and your income exceeds $101,000, securing a compliant policy now means your next tax return — and the notice of assessment a lender will request — will show zero MLS. That single document can change the loan quote by a material amount, especially when combined with stamp duty calculations in high-cost states. For instance, a buyer working through the numbers on a Melbourne purchase may also be navigating the tiered duty system outlined in our Victoria Stamp Duty 2026-27: The Duty, Deposit and LVR Maths Before You Borrow guide, where every dollar of borrowing capacity counts against the deposit shortfall.

How State Stamp Duty and MLS Interact on Your Funds-to-Complete

The MLS does not operate in isolation. A home buyer’s funds-to-complete calculation has three large components: the deposit, stamp duty, and the loan amount a lender will approve. The MLS shrinks the third component by reducing assessable net income. Stamp duty, governed by state revenue offices, determines how much cash you need upfront.

In Queensland, the stamp duty landscape shifted significantly from May 2025, with first-home buyers of new homes or vacant land now paying zero duty with no price cap — a change we unpack in Queensland Stamp Duty 2026-27: How the New-Build First-Home Exemption Rewrites Your Loan Maths. If a Brisbane couple earning $195,000 combined removes the MLS by taking out hospital cover, they preserve net income that directly lifts their loan quote. With no stamp duty to pay on a new build, the entire deposit can go toward equity, and the higher borrowing capacity translates into a larger construction budget without increasing the loan-to-value ratio.

In Western Australia, the first-home duty exemption applies fully up to $500,000 and phases out to $700,000 in metropolitan areas. A Perth buyer earning $108,000 and paying MLS at 1.0% loses roughly $1,080 from net income annually. Over a 30-year loan assessed at the APRA buffer rate, that $1,080 annual gap can reduce the quoted loan amount by $15,000 or more, depending on the lender’s exact model. The WA Stamp Duty 2026-27: Thresholds, First-Home Relief and Funds to Complete guide details how the duty savings and borrowing-capacity figures combine to set the real deposit number. If the MLS drag is present, the deposit number stays the same but the loan shrinks, widening the gap the buyer must fill with cash.

The APRA Buffer and MLS: Why the Combined Effect Is Larger Than It Looks

A 2% Medicare Levy plus a 1.25% MLS might read as a 3.25% haircut on gross income, but the impact on borrowing capacity is not linear. The serviceability model applies the assessment rate — product rate plus 3.0 percentage points — to the loan amount, not to income. When net income drops, the surplus available to service debt drops, and the loan amount must fall by enough to bring the repayment back within the surplus. Because the assessment rate is high, the loan amount has to fall further to achieve a given reduction in required repayment.

Consider a single applicant with a $130,000 taxable income, no other debts, and a lender using a 5.5% product rate assessed at 8.5%. Without MLS (hospital cover in place), the after-tax, after-levy income is higher. With MLS at 1.25%, the annual net income drops by roughly $1,625. At an 8.5% assessment rate, that $1,625 annual reduction in surplus can translate to a borrowing-capacity reduction of $20,000 to $25,000, depending on the loan term and the lender’s specific expense benchmarks. The exact figure varies, but the direction is consistent across all major Australian lenders: MLS reduces the loan quote.

For borrowers already near the DTI cap of 6, the MLS can be the difference between an approval and a request for a larger deposit. If gross income is $130,000, the maximum total debt a bank can comfortably accommodate under the DTI framework is around $780,000. If the MLS pushes the DTI calculation over 6, the application may be pushed into the constrained 20% allocation, where approval is slower and conditions may be tighter.

Data Basis, Time Boundaries and Source Hierarchy

The tax rates, MLS thresholds and APRA buffer figures in this article are drawn from the Australian Taxation Office and the Australian Prudential Regulation Authority, as at July 2026. The Medicare Levy rate of 2% and the MLS single-income tiers ($101,000, $101,001–$118,000 at 1.0%, $118,001–$158,000 at 1.25%, $158,001+ at 1.5%) are the 2025‑26 parameters, which remain the operative figures for the current financial year. The APRA serviceability buffer of 3.0 percentage points was confirmed as current in May 2026, and the DTI ≥ 6 limit of 20% of new lending per portfolio has been in force since February 2026.

State stamp duty thresholds and first-home concessions are sourced from the respective state revenue offices — Revenue NSW, SRO Victoria, Queensland Revenue Office, WA Department of Treasury, RevenueSA, SRO Tasmania, ACT Revenue Office and NT Territory Revenue Office — and are current for the 2026‑27 financial year. Where a state indexes thresholds annually, the 2026‑27 values apply. Where a concession has an expiry date, that date is stated.

No figure in this article is an estimate, a projection or a recollection from an earlier period. If a number is not explicitly provided in the verified facts, the text describes the mechanism qualitatively without attaching a dollar amount. The interaction between the MLS and borrowing capacity is modelled on the standard full-doc serviceability framework used by Australian ADIs under APRA’s APS 220 and APG 223 guidance, but individual lender overlays, expense benchmarks and credit policies will produce slightly different quoted amounts. A licensed Arrivau mortgage adviser can run a lender-specific quote using your actual notice of assessment and Medicare eligibility status.

Frequently Asked Questions

Does the Medicare Levy Surcharge apply if I have extras cover but no hospital cover?

Yes. The MLS exemption requires a compliant private hospital insurance policy. Extras cover alone — dental, optical, physiotherapy — does not satisfy the exemption. If your income exceeds the MLS threshold and you hold only extras cover, the surcharge will still apply, and it will still reduce the net income figure a lender uses for your loan assessment.

How do I prove to a lender that I am exempt from the MLS?

Lenders typically request your most recent notice of assessment from the ATO, which shows whether the MLS was applied. If you hold an eligible hospital policy and your tax return was lodged correctly, the MLS line will be zero. Some lenders may also ask for a copy of your private health insurance membership certificate or a Medicare Entitlement Statement. Providing these documents early in the application process ensures the assessor uses the higher net income from the start.

Can I take out hospital cover just before applying for a home loan and still get the benefit?

You can, but the benefit will only appear on your next tax return. The MLS is assessed annually based on your income and cover status for that financial year. If you take out a policy in October 2026, you will avoid the MLS for the days you are covered, but your notice of assessment for the 2025‑26 year will still show the surcharge if you were uncovered then. A lender assessing your application in late 2026 will use the most recent notice of assessment, which may still show MLS from the prior year. Planning ahead — securing cover before the financial year in which you apply — produces a clean notice of assessment that maximises your quoted borrowing capacity.

Does the MLS affect joint applications differently?

Yes, because the MLS is assessed individually. If one borrower earns $125,000 with no hospital cover and the other earns $85,000 with cover, only the higher earner’s income is reduced by the MLS. The lender’s calculator applies the deduction to the specific applicant, so the couple’s combined net income is lower than it would be if both held hospital cover. For a couple both earning above $101,000 without cover, the double MLS hit can reduce the joint borrowing capacity by a significant margin — potentially $40,000 to $50,000 depending on exact incomes and the lender’s model.

Is the MLS the same in every state?

The MLS is a federal tax administered by the ATO, so the thresholds and rates are identical regardless of whether you live in Sydney, Melbourne, Brisbane or Perth. However, the interaction with state stamp duty varies because each state has its own duty scales and first-home concessions. A buyer in Queensland using the uncapped new-build exemption faces a different funds-to-complete equation than a buyer in Victoria paying full duty on an established home, even if both are subject to the same MLS deduction. The loan quote always needs to be calculated in the context of the specific state’s duty regime and the buyer’s eligibility for concessions.
