Medicare Levy Surcharge 2026: How MLS Affects Your Mortgage Borrowing Capacity

How the Medicare Levy Surcharge (1.0%-1.5%) reduces borrowing power in 2026. ATO MLS thresholds, hospital cover vs MLS cost comparison, serviceability impact.

Medicare Levy Surcharge 2026: How MLS Affects Your Mortgage Borrowing Capacity

The Medicare Levy Surcharge (MLS) is an additional tax of 1.0% to 1.5% on taxable income if you earn above the ATO threshold and do not hold eligible private hospital cover. For the 2026 financial year, the single threshold is $101,000 and the family threshold is $202,000 (plus $1,500 per additional dependent child). The MLS sits on top of the standard 2% Medicare Levy. A single earner on $160,000 without hospital cover pays MLS of $2,400 plus the standard $3,200 levy — a combined $5,600 in Medicare-related charges. That money leaves your household every year and directly reduces the net income lenders use to calculate borrowing capacity. Under APRA’s 3% serviceability buffer, every dollar of MLS paid shrinks assessed loan principal by roughly $1.78. For a couple earning $220,000 combined without hospital cover, the MLS alone can reduce borrowing power by approximately $45,000.

Medicare Levy vs MLS

The standard Medicare Levy is a flat 2% of taxable income paid by most taxpayers. It funds the public system and cannot be avoided. Lenders already account for it in their serviceability calculators.

The MLS is an elective penalty on higher earners who choose not to hold a complying hospital policy. If you earn above the threshold and hold appropriate hospital cover, you pay zero MLS. If you do not, you pay the surcharge — one of the few household expenses that can be removed entirely by redirecting spend to a policy with its own tangible benefit.

MLS Thresholds and Tiers for 2026

The ATO sets MLS thresholds for each income year. For 2025–26 (assessed in your 2026 tax return), the single tiers are:

  • $101,000 or below: no surcharge
  • $101,001 to $118,000: 1.0%
  • $118,001 to $158,000: 1.25%
  • $158,001 and above: 1.5%

For families and couples, the combined MLS income threshold is $202,000, with an additional $1,500 added for each dependent child beyond the first. The surcharge rate applied to both partners is determined by the highest individual earner’s income tier.

Income for MLS purposes includes taxable income, reportable fringe benefits, and total net investment losses — a broader base than taxable income alone.

Hospital Cover vs MLS: The Simple Arithmetic

The cheapest complying hospital policies in 2026 start at approximately $1,200–$1,500 per year for a single adult under 65. For couples and families, the floor is roughly $2,400–$3,000. These are Basic or Bronze-tier policies — comprehensive Gold cover is not required to avoid the MLS. A policy with an excess of $750 (single) or $1,500 (couple/family) that includes restricted hospital treatment suffices.

A single earning $130,000 pays MLS of 1.25%, or $1,625 — a basic policy at $1,200 saves $425 and provides hospital cover. At $165,000, MLS is $2,475 versus $1,200: net saving $1,275. For a couple on $210,000 where the higher earner earns $160,000, MLS at 1.5% on both incomes totals $3,150. A family policy at $2,600 eliminates the surcharge and saves $550.

A narrow band exists — roughly $101,001 to $105,000 for singles — where MLS at 1.0% costs less than the cheapest policy. But this ignores the serviceability impact on a mortgage.

How MLS Reduces Your Borrowing Capacity

Australian lenders assess borrowing capacity using a net income surplus model. They deduct tax, the Medicare Levy, and living expenses from your gross income, apply a 3% serviceability buffer, and calculate the maximum loan you can service. When MLS appears as a deduction, it reduces your surplus before the buffer is applied.

Under the 3% buffer at 2026 rates, $1 of annual MLS reduces borrowing capacity by roughly $1.78 in loan principal. A single earning $130,000 paying $1,625 in MLS loses approximately $2,900 in borrowing capacity. A couple on $220,000 paying combined MLS of $3,300 loses roughly $5,900. A single on $200,000 pays $3,000 in MLS, reducing capacity by roughly $5,300.

For borderline applicants — common among first-home buyers in Sydney and Melbourne where median dwelling prices exceed $1.1 million in 2026 — removing the MLS by taking out hospital cover can be the difference between approval and decline. No lender will suggest this proactively. Their calculator pulls your taxable income from your notice of assessment and applies standard tax tables that include MLS if you have not declared private health cover.

Timing Hospital Cover With Your Mortgage Application

If you are planning to apply for a mortgage in the next 12 months, obtain a basic hospital policy at least three months before your application. This ensures your payslips and notice of assessment show the premium deduction rather than the MLS. If you purchase cover partway through the year, MLS is calculated pro-rata — you pay only for days uncovered.

The 2026–27 tax cuts reduce marginal rates for incomes between $45,001 and $135,000 (see our income tax guide), but the MLS operates independently. As marginal rates fall, the MLS becomes a larger share of your total tax. Combined with APRA’s 3% buffer (see our borrowing power analysis), removing the MLS can meaningfully shift the dial for applicants in the $100,000–$200,000 income band.

FAQ

Does the standard 2% Medicare Levy affect my borrowing capacity?

Not directly. Every lender’s serviceability calculator already deducts the Medicare Levy as part of the tax line — it is a universal cost. The MLS is elective, and eliminating it by purchasing basic hospital cover is a genuine step to improve your assessed net income.

Is a basic hospital policy enough to avoid the MLS?

Yes. A Basic or Bronze-tier hospital policy with an excess of $750 (single) or $1,500 (couple/family) or less is sufficient. You do not need Silver or Gold cover. Extras-only policies do not qualify. Confirm with your insurer that the product satisfies the ATO’s MLS exemption requirements.

How much can removing the MLS add to my borrowing capacity?

As a rough guide, every $1,000 of annual MLS eliminated adds approximately $1,700–$1,800 of borrowing capacity under the 3% APRA buffer at 2026 rates. A single earning $160,000 removing $2,400 in MLS gains roughly $4,200–$4,300. A family earning $250,000 combined could see $6,000–$7,000. These are indicative; an Arrivau adviser can run the exact calculation against your circumstances.
