Medibank Tax Statement Australia 2025: How to Find It and Use It at Tax Time

If you hold private health insurance with Medibank, you'll receive a private health insurance tax statement each year after 30 June. It's a short document but an important one — it contains the information you need to complete the private health insurance section of your Australian tax return. Getting it right affects your government rebate entitlement and can determine whether you're exempt from the Medicare Levy Surcharge. This guide explains exactly what your Medibank tax statement includes, where to find it, and how to use it correctly for FY 2025-26.

What Is the Medibank Tax Statement?

Your Medibank tax statement — officially known as a private health insurance statement — is an annual summary of your health cover for the financial year from 1 July to 30 June. Medibank is legally required by the ATO to issue this document to all members each year, and you are required to report the information it contains whenever you lodge your tax return and hold private health insurance.

The statement is not a bill or premium invoice. It's a reconciliation record showing what you paid, what government rebate was applied to your policy during the year, and how many days you held cover. The ATO uses this data to verify your rebate entitlement against your actual income and to confirm you're eligible for exemption from the Medicare Levy Surcharge.

Note that Medibank and ahm are separate insurers — Medibank Private Ltd owns ahm, but they operate independently. If you hold a Medibank policy, you'll receive a Medibank tax statement. If you hold an ahm policy, you'll receive a separate ahm statement. Make sure you're using the correct statement for the correct policy.

What Does the Medibank Tax Statement Include?

Your Medibank tax statement contains several fields that you'll enter directly into your tax return. Here's what each one means and why it matters:

The four key figures you'll actually enter into your tax return are: days of cover, benefit code, premiums paid, and government rebate received. Make sure these match your statement exactly — the ATO cross-checks this information with what Medibank reports directly to them.

The Private Health Insurance Rebate: How It Works with Medibank

The Australian government's Private Health Insurance Rebate helps reduce the cost of your Medibank cover. Most members receive this rebate as a reduction in their monthly or annual premium — so Medibank charges you less because the government contributes a portion directly. This is called taking the rebate "as a premium reduction" and is the default for most Medibank members.

Alternatively, you can elect to receive the rebate as a lump sum when you lodge your tax return. Either way, the ATO reconciles the correct amount at the end of the financial year using your Medibank tax statement and your actual income for the year.

The rebate is means-tested — it decreases as income rises and disappears entirely above the top income threshold. In FY 2025-26, the income tiers for singles are as follows:

Note: Rebate percentages are indexed annually. Check ato.gov.au for the exact rates applicable to FY 2025-26.

If your actual income at tax time is higher than you estimated when you first told Medibank which rebate tier to apply (which sets how much your premium was discounted), you'll need to repay some of the rebate through your tax return. If your income turned out to be lower, you may receive an additional rebate as a tax offset when you lodge.

How to Use Your Medibank Tax Statement in Your Tax Return

Whether you're lodging through myTax (the ATO's online lodgement system), a registered tax agent, or third-party tax software, you'll need to complete the Private Health Insurance section of your return. Here's how to do it step by step:

In many cases, myTax will automatically pre-fill your private health insurance details using data that Medibank reports directly to the ATO. Always check that the pre-filled details match your actual tax statement before lodging — pre-fill data can occasionally contain errors, and you're responsible for the accuracy of your return regardless.

Medibank Tax Statement and the Medicare Levy Surcharge

Your Medibank tax statement also plays a key role in determining whether you're liable for the Medicare Levy Surcharge (MLS). The MLS is an additional tax — on top of the standard 2% Medicare Levy — that applies to higher earners who don't hold an eligible hospital cover policy for the full financial year.

In FY 2025-26, the MLS applies if your income exceeds $101,000 (for singles) and you did not maintain continuous, complying hospital cover. The surcharge rates are:

• $101,001 – $118,000: 1.0% MLS on your total taxable income
• $118,001 – $158,000: 1.25% MLS on your total taxable income
• $158,001+: 1.5% MLS on your total taxable income

Your Medibank tax statement — particularly the days of cover field and the benefit code confirming you hold hospital cover — is what proves to the ATO that you maintained an eligible hospital policy. If you held Medibank hospital cover for all 365 days of the financial year, you're fully exempt from the MLS. If there was a gap (for example, you cancelled your policy mid-year or switched insurers with a break in cover), you may owe MLS for those uncovered days.

Important: extras-only cover (dental, optical, physio, etc.) does not exempt you from the Medicare Levy Surcharge. You must hold a complying hospital policy to avoid the surcharge. Check your benefit code on the Medibank statement — hospital cover is typically indicated by a benefit code of "X" (hospital and extras combined) or "S" (hospital only).

What If You Can't Find Your Medibank Tax Statement?

If July or August has come and gone and you still don't have your Medibank tax statement, here's what to do:

• Check your email inbox and spam/junk folder — Medibank sends statements electronically to members who've registered for digital communications
• Log in to medibank.com.au → My Membership → Documents or Tax Statement — you can download current and previous years' statements from the member portal
• Check myTax pre-fill — the ATO often receives your health insurance data directly from Medibank. Wait until late July, then log in to myTax to see if the details have been pre-filled
• Call Medibank on 132 331 — their member services team can resend your statement by email, or confirm the key figures over the phone if you need them urgently
• Check your registered address and email — if you've moved house or changed email and didn't update your details with Medibank, your statement may have gone to the old address

Don't lodge your tax return with missing or incorrect private health insurance details. An error in this section can result in an incorrect rebate calculation, an ATO audit flag, or an unexpected adjustment later. If you're unsure, wait for your statement before lodging.
