The Single Income Family Supplement (SIFS) is a small, once-a-year payment of up to $300 for certain single-income families.
It was closed to new applicants from 1 July 2017, so in 2025 it only applies to families who already qualified on 30 June 2017 and have kept their eligibility since then.
If you’re unsure whether you still qualify, the guide below explains the rules, timing and the steps to claim.
What Is The Single Income Family Supplement?
The SIFS is designed to support households where there is one main income earner.
The final amount (up to $300 per year) is calculated after the end of the financial year when your Family Tax Benefit (FTB) is balanced.
The more days you were eligible during the year—and the more your income fits the rules—the closer you’ll be to the maximum $300.
Who Can Get It In 2025?
You may be eligible in 2025 if all of the following apply:
- You were eligible on 30 June 2017 and have had no break in eligibility since.
- Your household has one primary earner with taxable income between $68,000 and $150,000.
- Any second earner in the family has taxable income under $18,000.
- You care for at least one FTB-eligible child (or would be eligible for FTB but for income or certain at-home study payments).
Important: Because SIFS is grandfathered, most families cannot newly apply in 2025. If you didn’t meet the rules on 30 June 2017, you generally won’t be able to start now.
How Much And When Is It Paid?
- Amount: Up to $300 per eligible family, once a year.
- When: After EOFY, once your FTB is balanced—usually after you lodge your tax return or confirm you don’t need to lodge.
- How You’re Paid: The supplement is added to your FTB balancing outcome. It’s not a fortnightly payment.
How To Claim In 2025
- Already receiving FTB: You usually don’t need a separate claim. If you’re still eligible for SIFS, it will be assessed automatically at balancing.
- Not receiving FTB but previously eligible for SIFS: You can submit a lump-sum claim after the financial year via myGov → Centrelink under Family Assistance.
- Deadlines: You typically have 12 months after 30 June to lodge your tax return/confirm income and submit any lump-sum claim.

Also check any state or territory cost-of-living concessions that match your situation.
In 2025, the $300 Single Income Family Supplement continues as a grandfathered support for families who qualified on 30 June 2017 and maintained eligibility.
The payment is calculated after tax time, appears with your FTB balancing, and does not require a separate claim for most families on FTB.
If you’re uncertain, review the income thresholds, confirm your FTB status, and, if needed, lodge a lump-sum claim via myGov within the 12-month window after the financial year ends.
