Australian families relying on a single primary income earner may still be eligible for a valuable annual government payment in 2026. The Single-Income Family Supplement (SIFS) offers up to $300 per year to qualifying households raising children on one main income.
While the payment amount may seem modest, it can provide meaningful assistance amid rising household expenses. However, eligibility rules are strict, and not all families can access it. Here’s a clear, updated guide to understanding who qualifies and how to claim the supplement in 2026.
What Is the Single-Income Family Supplement?
The Single-Income Family Supplement is an annual lump-sum payment rather than a fortnightly benefit. It was introduced to assist families where one person earns most or all of the household income while caring for dependent children.
Unlike other family assistance payments, SIFS is assessed after the financial year ends. Payments are processed once income details and family circumstances have been reviewed.
The supplement forms part of Australia’s broader family support system and works alongside Family Tax Benefit (FTB) payments.
Important Eligibility Rule for 2026
One of the most important conditions for the 2026 payment is historical eligibility.
To qualify in 2026, families must:
- Have been eligible for the Single-Income Family Supplement on 30 June 2017
- Have continued to meet the eligibility conditions since that date
This means new applicants who did not qualify before the 2017 cut-off cannot newly access this supplement in 2026.
Who Can Receive the Payment?
To be eligible in 2026, families must meet all of the following criteria:
- There must be one main income earner in the household
- The primary earner’s taxable income must be between $68,000 and $150,000
- If there is a second earner, their income must be under $18,000
- The family must be caring for at least one eligible dependent child
- The family must either receive Family Tax Benefit or meet the requirements for it
Eligibility is assessed based on taxable income for the financial year, not projected income.
How Much Can You Receive?
The maximum annual payment under the Single-Income Family Supplement is $300.
The exact amount depends on:
- Total household taxable income
- The number of days during the financial year the family cared for an eligible child
Families who only met eligibility criteria for part of the year may receive a reduced amount.
Because the payment is calculated after the financial year ends, families typically receive it once tax returns and income details are finalised.
How the Claim Process Works
The process for receiving the supplement depends on whether your family already receives Family Tax Benefit.
If You Receive Family Tax Benefit
Families already receiving Family Tax Benefit do not need to lodge a separate claim for the Single-Income Family Supplement.
Once your annual FTB reconciliation is completed and your income has been confirmed, eligibility for the supplement will be automatically assessed. If you qualify, the payment will be added to your reconciliation outcome.
If You Do Not Receive Family Tax Benefit
Families who do not currently receive Family Tax Benefit but meet the eligibility conditions must lodge a separate claim.
Steps to claim:
- Confirm eligibility, including historical eligibility dating back to 30 June 2017
- Gather supporting documents such as tax returns and proof of dependent children
- Log in to your Centrelink online account via myGov
- Submit your claim after the financial year has ended
- Provide any additional documents requested
- Wait for Services Australia to assess your claim
Claims are generally processed once all required income data has been verified.

Why This Payment Still Matters
Although the payment amount is capped at $300 per year, it can help offset expenses such as:
- School supplies
- Utility bills
- Transport costs
- Groceries
For families managing on a single income, even small annual supplements can ease financial pressure.
The supplement also recognises the financial structure of single-income households, particularly where one parent remains at home to care for children.
Common Mistakes to Avoid
Many families miss out due to misunderstandings about eligibility. Key points to remember:
- New applicants who were not eligible in 2017 cannot access the supplement
- Both income thresholds must be met
- Income must be based on actual taxable earnings
- Claims are only assessed after the financial year ends
Ensuring your tax returns are lodged promptly can help avoid delays.
