FTB End of Year Supplement: How It Works and How to Get Paid in 2026
The Family Tax Benefit supplement can pay you up to $850 per child per year — but only if you lodge your tax return on time. Here is how it works.
What Is the FTB Supplement?
The Family Tax Benefit (FTB) supplement is a lump sum payment made after the end of the financial year once you (and your partner, if applicable) have lodged your tax returns or confirmed you do not need to lodge. The FTB Part A supplement is worth up to $850.70 per child per year. The FTB Part B supplement is worth up to $430.70 per family per year. These amounts are held back from your fortnightly payments and paid as a lump sum to reduce the risk of overpayments. For a family with 3 children receiving both FTB Part A and Part B, the total supplement could be ($850.70 times 3) plus $430.70 equals $2,982.80 per year. The supplement is intended as a top-up to ensure you received the correct amount over the year and is only paid if your actual income was at or below the relevant thresholds.
When and How the Supplement Is Paid
The FTB supplement for the 2024-25 financial year is paid after you lodge your 2024-25 tax return. Once both you and your partner have lodged (or confirmed non-lodgement), Centrelink performs a reconciliation — comparing your estimated family income (used to calculate fortnightly payments) with your actual taxable income from the ATO. If your actual income was lower than estimated, you may receive additional FTB on top of the supplement. If your income was higher, you may owe a debt which is offset against the supplement (reducing or eliminating it). The supplement typically arrives 2 to 4 weeks after reconciliation is complete. If you lodge your tax return by 30 June 2026 (for the 2024-25 year), you will generally receive your supplement between July and September 2026. Delays in lodging mean delays in receiving the supplement.
The Deadline You Cannot Miss
You must lodge your tax return (or confirm you do not need to lodge) by 30 June of the following financial year or you lose the supplement entirely. For the 2024-25 financial year, the deadline is 30 June 2026. If you miss this deadline, you forfeit the entire FTB Part A supplement ($850.70 per child) and Part B supplement ($430.70) — there is no extension or appeal. If you do not need to lodge a tax return (because your income was below the tax-free threshold of $18,200), you must advise Centrelink of this through your myGov account by selecting "I am not required to lodge a tax return" for the relevant year. This is a commonly missed step — many families on low incomes assume Centrelink knows they do not need to lodge, but the system requires explicit confirmation. Set a calendar reminder for May each year to check this.
Income Limits for the Full Supplement
The FTB Part A supplement is income-tested. You receive the full $850.70 per child if your adjusted taxable income (ATI) is $83,280 or less. Between $83,280 and $103,368, the supplement reduces by 30 cents for every dollar of income over the lower threshold. Above $103,368, there is no Part A supplement but you may still receive the base rate of FTB Part A (which has a separate, higher income test). The FTB Part B supplement of $430.70 is available to families where the lower-earning partner has an ATI of $117,194 or less per year. For single parents, Part B has no income test — you receive the full supplement regardless of your income. Adjusted taxable income includes taxable income plus reportable fringe benefits, net investment losses (including negative gearing), reportable employer super contributions, and tax-exempt foreign income. Salary sacrificing into super can reduce your ATI and help you stay under the threshold.
FTB Reconciliation: Debts and Top-Ups
When Centrelink reconciles your FTB after you lodge your tax return, three outcomes are possible. If your actual income matches your estimate, you receive the supplement with no adjustment. If your actual income was lower than your estimate, you receive a top-up payment — this can be substantial if you significantly over-estimated your income during the year. If your actual income was higher than your estimate, you may have been overpaid FTB and will owe a debt. The supplement is used to offset any debt first. For example, if your FTB debt from reconciliation is $500 and your supplement is $850.70, you would receive $350.70 net. If the debt exceeds the supplement, the remaining amount is recovered through future Centrelink payments or your tax refund. To minimise the risk of debts, update your income estimate in myGov whenever your circumstances change — a pay rise, new job, or partner starting work should all be reported promptly.
Lump Sum FTB Claims
If you did not receive FTB during the year (perhaps you did not know you were eligible, or your circumstances changed mid-year), you can make a lump sum claim after the end of the financial year. You have until 30 June of the following year to lodge a lump sum claim — for the 2024-25 financial year, the deadline is 30 June 2026. Lump sum FTB includes the supplement if your income is within the thresholds. To claim, lodge through your myGov account under "Make a claim" and select Family Tax Benefit Lump Sum. You will need details of your children, your (and your partner's) income, and your living arrangements during the relevant period. Lump sum claims can be backdated to cover the entire financial year, so even if you only became eligible for part of the year (for example, you had a baby in March), you receive FTB for that period plus the pro-rata supplement.
