1. The Australian Family Tax Benefit Framework (2026–27)

Family assistance in Australia is administered by Services Australia under A New Tax System (Family Assistance) Act 1999.

Understanding how FTB Part A and Part B income tests, maintenance income testing, and end-of-year supplements interact ensures eligible families maximize financial assistance while avoiding debt balancing overpayments.

3. The Mathematics of Income Taper Reductions & Supplements

Fortnightly FTB Part A Payment (FTBA_fn) for maximum rate (Max_rate), combined income (ATI), lower threshold (T_low), and taper rate (20c) is:

FTB Part A Reduction ($/yr) = (ATI - $69,131) × 0.20
Maintenance Income Reduction ($/yr) = (Child Support Received - $2,080.50) × 0.50
Part B: not calculated without exact youngest-child age and each parent’s income.
End-of-year supplements and maintenance-income adjustments: not included.

Example Calculation ($85,000 Combined Family ATI, 2 Children Aged 4 & 8):
- Maximum FTB Part A Base Rate: $235.48 × 2 = $470.96 / fortnight ($12,278.60 / year).
- Income Taper Reduction ($85,000 vs $69,131 threshold): ($85,000 - $69,131) × 20% = $3,173.80 reduction / year.
- Payable FTB Part A = $12,278.60 - $3,173.80 = $9,104.80 / year ($349.23 / fortnight).

Frequently Asked Questions (FAQ)

What is the difference between Family Tax Benefit Part A and Part B in Australia?

FTB Part A is paid per child based on total combined family income to assist with general raising costs. FTB Part B provides extra assistance to single-parent families, non-parent carers, and couple families where one parent is the primary earner.

Maximum fortnightly rates include: $235.48 / fn for each child aged 0–12, $306.46 / fn for each child aged 13–19 (in secondary study). Families earning under ~$69,131 receive maximum FTB Part A.

How does the Maintenance Income Test (MIT) affect FTB Part A?

Child support payments received above the Maintenance Income Free Area (~$2,080.50/yr) reduce your FTB Part A by 50 cents for every dollar of child support received above the threshold.

What are the End-of-Year FTB Supplement payments?

Supplements are assessed after balancing and are excluded here. Part A supplement has an $80,000 family income limit; other eligibility and reporting requirements also apply.

What is the "No Jab, No Pay" rule for Family Tax Benefit Part A?

Immunisation and Healthy Start for School requirements can affect Part A payment rates. Check Services Australia for the requirements and any applicable exemptions.
