Key Takeaway

The Australian private health insurance rebate reduces your premium cost through a government contribution, calculated using three factors: your income for Medicare Levy Surcharge (MLS) purposes, your age on 1 July of the relevant year, and your policy tier (hospital, extras, or combined). The rebate percentage ranges from 0% to 33.468% for 2025-26, with higher earners receiving a lower rebate or none at all. Use the calculator below to determine your exact entitlement based on your personal circumstances.

What is the Private Health Insurance Rebate?

The private health insurance rebate is a government contribution that reduces the cost of your private health insurance premium. Administered by the Australian Taxation Office, the rebate is available to all Australians with eligible hospital, extras, or combined private health insurance policies (ATO, 2026).

You can claim the rebate as a direct premium reduction (your insurer applies it immediately, and you pay the lower amount) or as a tax offset when you lodge your annual tax return. Most Australians choose the premium reduction because it provides immediate relief on every payment cycle.

The Three Factors That Determine Your Rebate

Understanding how the rebate works requires examining three core variables, as covered in foundational finance texts such as Principles of Finance: your income, your age, and your policy tier.

Income for MLS Purposes

Your rebate percentage is determined by your income for Medicare Levy Surcharge purposes, which includes taxable income, reportable fringe benefits, total net investment losses, and reportable superannuation contributions. The Australian Taxation Office sets income thresholds each financial year, with separate thresholds for singles and families (ATO, 2026).

For the 2025-26 income year, the thresholds are divided into three tiers. Higher income earners receive a lower rebate percentage, with Tier 3 earners (singles earning over A$151,000 or families over A$302,000) receiving no rebate at all.

Age on 1 July

Your age on 1 July of the relevant income year determines which age-based rebate bracket you fall into. There are three age brackets: under 65, 65 to 69, and 70 or older. Older Australians receive a higher rebate percentage within each income tier, recognising that health insurance premiums generally increase with age (APRA, 2026).

If you turn 65 or 70 during the financial year, your rebate is calculated using the age you were on 1 July, not your age when you pay the premium or lodge your tax return.

Policy Tier

The rebate applies to complying health insurance products regulated by the Australian Prudential Regulation Authority. You can claim the rebate on hospital cover, general treatment (extras) cover, or a combined policy. The rebate percentage is the same regardless of which tier you choose, but it only applies to the component of your premium that covers you, your partner, and dependent children under certain age limits.

Premiums for adult dependants over 25 (or over 31 if they are full-time students) are not eligible for the rebate.

How the Rebate Percentage is Calculated

The rebate percentage is a fixed rate set by the government each year, based on the combination of your income tier and age bracket. For 2025-26, the percentages range from 8.202% (Tier 2, under 65) to 33.468% (Tier 0, aged 70 or older).

These percentages are indexed annually and typically announced by the Australian Taxation Office in March or April for the coming financial year. Once you know your income tier and age bracket, your rebate percentage is locked in for that entire year, even if your income fluctuates during the year (MoneySmart, 2026).

Why Use a Rebate Calculator?

Calculating your rebate manually requires identifying your income tier, determining your age bracket, cross-referencing the ATO rebate percentage table, and then applying that percentage to your annual premium. A dedicated calculator simplifies this process by asking for your income, age, and policy details, then instantly returning your rebate entitlement in dollar terms.

The calculator below accounts for current-year thresholds and percentages, making it straightforward to estimate your annual rebate and decide whether to claim it as a premium reduction or a tax offset. It also helps you model scenarios, such as how a pay rise might affect your rebate in the next income year, or whether income splitting strategies could move you into a higher rebate tier.

Important Considerations

The rebate is not automatic. If you choose to claim it as a premium reduction, you must notify your health insurer of your income tier each year. If you underestimate your income and claim a higher rebate than you are entitled to, you will owe the difference at tax time.

Before relying on a rebate estimate, confirm your income for MLS purposes by reviewing your previous year’s tax return or consulting a registered tax agent. Income thresholds and rebate percentages change annually, so always verify the current-year rates with the Australian Taxation Office before making coverage decisions.

This is general information only and does not take into account your objectives, financial situation, or needs. Before acting on it, consider whether it is appropriate for you, read the relevant Product Disclosure Statement (PDS) from your health insurer, and consider obtaining personal advice from a licensed financial adviser or registered tax agent. The rebate is a tax matter administered by the ATO; coverage terms and exclusions are set by your insurer and regulated by APRA.
