What is Family Tax Benefit?
Family Tax Benefit (FTB) is a Centrelink payment to help families with the cost of raising children. It has two parts: Part A (per child, income-tested on combined family income) and Part B (per family, helping single-income families and single parents).
How this calculator works
This calculator applies the 2025-26 maximum fortnightly rates and Australian government income tests. Part A reduces 20c per dollar above $66,722 (down to base rate), then 30c per dollar above $118,771. Part B is income-tested on the primary earner (cap $120,007) and reduces with the secondary earner's income (free area $6,935, then 20c/$). Single parents typically get full Part B regardless. The Part A Supplement (~$938/child/year) is paid as a lump sum after EOFY if family income is ≤ $80,000.
FTB Part A — Per Child
Maximum fortnightly Part A rates (2025-26): $227.36 per child aged 0-12, $295.82 per child aged 13-19 in approved education. The 'base rate' (everyone above the income threshold but below the cut-off) is $72.94 per child. Two income tests apply — Centrelink uses whichever gives you the higher payment, except above the higher threshold ($118,771) where only Method 2 applies.
FTB Part B — Per Family
Part B helps single-income couples and single parents. Maximum rates: $193.34/fn if youngest child is under 5, $134.96/fn if youngest is 5-13 (or up to 18 for single parents). For couples: zero Part B if primary earner > $120,007. Above the secondary earner free area ($6,935), Part B reduces 20c per dollar.
Adjusted Taxable Income (ATI)
FTB income tests use ATI, not your tax-return taxable income. ATI = taxable income + reportable fringe benefits + reportable super contributions + total net investment loss (negative gearing added back) + tax-free pensions + foreign income. Many families are surprised their ATI is higher than expected — this can reduce FTB more than they planned.
Conditions and Reconciliation
FTB has compliance requirements: child immunisation/health-check requirements, school attendance for school-age children, claiming child support if separated. Centrelink reconciles your fortnightly FTB at EOFY against your actual income. If you under-estimated income, you may need to repay; over-estimate and you get the Supplement plus any top-up.
Worked Examples
Couple, 2 children (8 and 11), combined income $90,000, single earner
Annual FTB Part A: ~$11,822 + Part B ~$3,510 = ~$15,332
- FTB Part A max: 2 × $227.36 × 26 = $11,822.72/year
- Income $90K is above lower threshold ($66,722), but Method 1 still beats Method 2
- Reduced amount > base rate, so applies
- FTB Part B: youngest is 8, so $134.96 × 26 = $3,508.96
- Single-earner couple: full Part B (secondary earner $0)
- Plus Part A Supplement (income > $80K threshold, no supplement)
- Total annual: ~$15,332
