What Is the FTB Supplement and How Does It Work?

The Family Tax Benefit supplement is an annual bonus payment that Services Australia makes to eligible families after the end of each financial year. Unlike your regular fortnightly FTB payments, which are based on an income estimate you provide during the year, the supplement is calculated when your actual income is confirmed through the tax return reconciliation process.

The supplement exists to help families with the costs that come up throughout the year — school fees, uniforms, extracurricular activities, and other children's expenses that don't fit neatly into a fortnightly budget. It's paid as a lump sum, typically in July or August after you've lodged your tax return, and it can make a meaningful difference to your annual household finances.

There are two separate supplements: the Part A supplement (paid per child) and the Part B supplement (paid per family). Each has its own eligibility criteria, income thresholds, and maximum payment rates. Understanding both components helps you estimate how much you'll receive at the end of the year and plan your family budget accordingly.

FTB Part A Supplement: Rates and Eligibility for 2025-26

The Part A supplement is paid per child and is the larger of the two supplements. For the 2025-26 financial year, the maximum Part A supplement is $879.65 per child. This means a family with two eligible children could receive up to $1,759.30 in Part A supplements alone, plus any Part B entitlements.

However, not everyone receives the full amount. The Part A supplement is subject to an income test. If your family's adjusted taxable income exceeds $80,000, your supplement reduces by 30 cents for every dollar over that threshold until it reaches zero. This taper rate means the supplement phases out relatively quickly once you move into higher income brackets.

To be eligible for the Part A supplement, you must meet several conditions. Your child must meet the immunisation requirements (or have an approved exemption), you must be an Australian resident, and your family's income must be within the applicable threshold. If you received FTB Part A during the year through fortnightly payments, you'll generally receive the supplement automatically. If you didn't receive fortnightly payments but are eligible for the supplement, you may still receive it after lodging your tax return — but you need to claim it.

FTB Part B Supplement: What You Need to Know

The Part B supplement provides additional support for single parents and families with one main income earner. For 2025-26, the maximum Part B supplement is $423.35 per family. Unlike Part A, which is paid per child, Part B is paid once per family regardless of how many children you have.

Eligibility for the Part B supplement is tied directly to your FTB Part B eligibility during the financial year. If you received any FTB Part B payments — even a reduced amount due to income — you may be entitled to the Part B supplement. The supplement is also subject to the same income tests that apply to regular Part B payments. For couples, the primary earner's income must be $110,000 or less, and the supplement phases out gradually as income approaches this threshold.

Single parents are generally eligible for Part B if their youngest child is under 16 (or under 18 if studying). Couple families are eligible if their youngest child is under 13. If your youngest child turns 13 during the year, your Part B entitlement may cease partway through the financial year, which also affects your supplement eligibility.

It's worth noting that the Part B supplement is not a separate payment you need to apply for. If you're entitled to it, you'll receive it automatically after you lodge your tax return and Services Australia reconciles your income. However, if you don't lodge your tax return, you won't receive the supplement, which is why timely lodgement is so important for FTB recipients.

How the FTB Supplement Is Calculated

Understanding how the supplement is calculated helps you estimate what you'll receive at the end of the year. The calculation is not simply "maximum rate minus income test reduction." Instead, the supplement is calculated as part of the broader FTB reconciliation process that happens after you lodge your tax return.

Here's how it works. Throughout the financial year, you receive fortnightly FTB payments based on the income estimate you provided to Services Australia. At the end of the year, when you lodge your tax return, the ATO tells Services Australia your actual adjusted taxable income. Services Australia then calculates what your FTB entitlement should have been, including both the fortnightly amounts and the annual supplement. If you were underpaid during the year (because your actual income was lower than your estimate), you'll receive a top-up payment that includes the supplement. If you were overpaid, the supplement may be used to offset the overpayment, and you may receive the balance.

The supplement itself is calculated as follows. First, Services Australia determines whether your family's adjusted taxable income is below the supplement income threshold. For Part A, if your ATI is below $80,000, you receive the full $879.65 per child. If it's above $80,000, the supplement reduces by 30 cents for every dollar of excess income. For Part B, the same rules that apply to your regular Part B payments also apply to the supplement.

Let's look at a practical example. Suppose you have two children and your family's adjusted taxable income is $85,000. Your Part A supplement would be $879.65 × 2 = $1,759.30, minus 30c × $5,000 = $1,500 reduction, leaving $259.30 per child. That's $518.60 total for Part A. If you also qualify for Part B (for example, as a single parent), you'd receive up to an additional $423.35, bringing your total supplement to approximately $941.95. This example shows how the supplement can still be valuable even for families earning well above the base thresholds.

How to Claim the FTB Supplement

For most families, claiming the FTB supplement is automatic. Here's what you need to do to ensure you receive everything you're entitled to without unnecessary delays.

First, lodge your tax return on time. This is the single most important step. Services Australia uses the information from your tax return to reconcile your FTB entitlement and calculate the supplement. If you don't lodge, the reconciliation can't happen, and you won't receive the supplement. For the 2025-26 year, the tax return deadline is 31 October 2026 (or later if you use a registered tax agent).

Second, meet the immunisation requirements. For the Part A supplement, your children must be fully immunised according to the National Immunisation Program Schedule, or have a valid exemption. If your immunisation status isn't up to date, Services Australia may hold your supplement until you provide evidence of compliance. You can check your children's immunisation status through your Medicare online account or by contacting your GP.

Third, keep your income estimate realistic throughout the year. While the supplement is calculated at year-end, the reconciliation process can be disrupted if your income estimate was wildly inaccurate. Regular updates to your estimate help ensure a smooth reconciliation and faster payment of any supplements you're owed.

Fourth, make sure your family circumstances are correctly recorded with Services Australia. This includes the number and ages of your children, your relationship status, and your care arrangements. If any of these details change during the year, update them promptly. Incorrect information can delay your reconciliation and supplement payment.

FTB Supplement vs Regular FTB Payments: Key Differences

Many families confuse the FTB supplement with regular FTB payments, but they serve different purposes and are treated differently by the tax system. Understanding the difference helps you plan your family budget more effectively.

Regular FTB payments are paid fortnightly or as a lump sum at the end of the year (if you choose that option). They're based on your income estimate and are designed to help with ongoing costs throughout the year. The supplement, by contrast, is an additional bonus paid after the financial year ends, based on your actual income. It's not part of your regular entitlement — it's an extra payment on top.

Another important difference is that the supplement is not included in your annual FTB income cap. For Part A, there's a cap on total FTB payments of approximately $2,800 per child per year (for children under 13). The supplement sits outside this cap, meaning it doesn't reduce your fortnightly payments. It truly is a bonus.

If you're trying to estimate your total family support for the coming year, use our take-home pay calculator to understand your net income from employment, and combine that with your expected FTB entitlements including the supplement. This gives you a realistic picture of your family's total financial position for budgeting purposes.

How FTB Supplements Affect Your Tax Position

One common question is whether the FTB supplement is taxable income. The good news is that FTB payments — including the supplement — are not considered taxable income in Australia. You do not need to declare them on your tax return, and they won't affect your tax bracket, Medicare levy, or any other tax obligations.

However, the supplement does affect your overall financial picture in other ways. Because the supplement is calculated based on your adjusted taxable income, it's indirectly connected to your income tax position. If you have income from other sources — salary, business earnings, investment income — your total ATI determines whether you receive the full supplement or a reduced amount.

For example, if you're close to the $80,000 ATI threshold for the Part A supplement, making additional superannuation contributions through salary sacrifice could reduce your ATI and potentially increase your supplement. Similarly, if you have a HECS-HELP debt, your compulsory repayments don't reduce your ATI for FTB purposes, so they won't help you retain the supplement.

Understanding these interactions helps you make smarter financial decisions. If you're considering salary sacrificing to super, contributing more to your super account, or adjusting your investment strategy, it's worth modelling how these changes affect your ATI and, in turn, your FTB supplement entitlement. Our salary sacrifice calculator can help you estimate the impact of super contributions on your overall financial position.

Frequently Asked Questions

Do I need to apply for the FTB supplement separately?

No. The supplement is calculated automatically as part of the FTB reconciliation process after you lodge your tax return. Services Australia determines your eligibility and pays the supplement into your nominated bank account, usually in July or August following the end of the financial year.

What if I didn't receive fortnightly FTB during the year?

You may still be eligible for the supplement if your family's income is within the applicable thresholds and you meet all other eligibility requirements. However, you need to lodge a claim for FTB and your tax return to trigger the reconciliation process. The supplement is not available to families who never claimed FTB at all.

Can I choose to receive the supplement fortnightly instead of as a lump sum?

No. The supplement is an annual payment only. It's designed to be paid after the end of the financial year when your actual income is confirmed through the reconciliation process. If you prefer more consistent payments throughout the year, you can adjust your regular FTB payment rate by updating your income estimate.

What happens to the supplement if I have an FTB overpayment debt?

If you were overpaid FTB during the year, Services Australia may use your supplement to offset the overpayment. You'll receive any remaining balance. If the overpayment is larger than the supplement, you may need to repay the difference. This is why accurate income estimation throughout the year is so important.

Does the Medicare levy affect my FTB supplement?

Not directly. The Medicare levy is calculated based on your taxable income from your tax return, while the FTB supplement is based on your adjusted taxable income for Centrelink purposes. However, because both use income-based calculations, changes to your income affect both your supplement entitlement and your Medicare levy obligation.

Will the FTB supplement affect my other Centrelink payments?

The supplement is treated as a lump sum payment and generally doesn't affect your other Centrelink payments like JobSeeker or Parenting Payment. It's not counted as income for the purposes of income tests on other payments. However, if the supplement is deposited into a bank account, it may count as an asset after a certain period, which could affect asset-tested payments like the Age Pension.
