Private Health Insurance: Rebate, Surcharge and the Age-31 Deadline
Australia nudges you into private hospital cover with three interlocking levers: a rebate that discounts premiums, a surcharge that taxes higher earners who go without, and a loading that penalises starting late. Whether cover is worth it is mostly a question of which levers apply to you.
Lever 1: the Medicare Levy Surcharge (MLS)
Everyone pays the 2% Medicare levy. On top of that, if you don't hold private hospital cover and your income for surcharge purposes exceeds the threshold, you pay the MLS:
| Income (single / family, 2024–25) | Surcharge |
|---|---|
| Up to $97,000 / $194,000 | 0% |
| $97,001–$113,000 / $194,001–$226,000 | 1% |
| $113,001–$151,000 / $226,001–$302,000 | 1.25% |
| Above $151,000 / $302,000 | 1.5% |
A single on $120,000 with no cover pays a $1,500 surcharge — while basic hospital policies start around $1,200–$1,500/year. Above the threshold, cover is often cheaper than the tax it avoids, which is exactly the policy's intent.
Lever 2: the income-tiered rebate
The government refunds part of your premium, claimable as an upfront discount or at tax time. For under-65s it runs from roughly 24.6% at the base tier down to 0% above the top MLS threshold, with higher percentages at older ages. Tell your insurer the right tier — claiming too high a rebate is squared up (against you) in your tax return.
Lever 3: Lifetime Health Cover loading
- Take out hospital cover by 1 July after your 31st birthday or pay a 2% loading per year of delay on top of premiums — up to 70%.
- Start at 40 instead of 31 and you pay 20% more for the same policy, for up to 10 years before the loading drops off.
- The rebate doesn't apply to the loading component — late starters pay it in full.
The honest decision rule: above the MLS threshold, basic hospital cover usually wins on tax arithmetic alone. Below it, the case rests on what you'd actually use — private obstetrics, elective surgery wait times, choice of doctor — not on tax. "Junk" policies that only dodge the MLS do exactly that and little else; read the tier (Basic/Bronze/Silver/Gold) before buying.
