About the Family Tax Benefit Calculator
Family Tax Benefit (FTB) is the main Centrelink payment that helps Australian families with the cost of raising children. This calculator estimates both parts for the 2026–27 financial year. FTB Part A is paid per child and is income-tested on your combined family adjusted taxable income (ATI); FTB Part B is paid per family to single parents and to couples with one main income, and is tested on the secondary earner’s income.
Part A starts at $6,139.30 a year for each child under 13 and $7,989.85 for each teenager aged 13–15 (or 16–19 in secondary school). It reduces by 20 cents for each dollar of family income above $69,131 until it reaches the base rate of $1,971 per child, then by 30 cents per dollar above $123,078. Part B is $5,223.15 a year if your youngest child is under 5 or $3,646.35 if they are 5 to 12 (up to 18 for single parents), and stops entirely if the primary earner’s income is over $124,327.
Supplements of up to $970.90 per child (Part A, family income up to $80,000) and $478.15 per family (Part B) are paid as a lump sum after the year is reconciled. Maintenance income, Rent Assistance, the Newborn Supplement and shared-care percentages are not modelled, so check your entitlement in your Centrelink online account.
With the default inputs, the total ftb per year is $9,236.90. Change any value above to recalculate instantly.

Formula and method
FTB Part A uses two methods and pays the higher. Method 1 starts from the maximum rate (standard rate for each child plus the supplement) and reduces it by 20 cents per dollar of family adjusted taxable income (ATI) above $69,131, but not below the base rate. Method 2 starts from the base rate ($1,971 per child plus supplement) and reduces it by 30 cents per dollar above the higher income free area of $123,078. The FTB Part A supplement ($970.90 per child) is only paid if family ATI is $80,000 or less.
FTB Part B is not payable if the primary earner’s ATI is over $124,327. Otherwise it is $5,223.15 (youngest under 5) or $3,646.35 (youngest 5–12, or up to 18 for single parents) plus a $478.15 supplement, reduced by 20 cents for each dollar of the secondary earner’s income above $7,154. Fortnightly amounts are the yearly rate without supplements × 14 ÷ 365.

Worked examples
Couple, two young children, $95,000 family income
Family income of $95,000 is $25,869 above $69,131, cutting the $12,278.60 Part A maximum by $5,173.80 to $7,104.80 (no supplement above $80,000). Part B for a youngest child under 5 is $5,701.30 with supplement, less 20% of the partner’s $17,846 above $7,154 ($3,569.20), leaving $2,132.10.
Single parent, one child aged 8, $40,000 income
Income is below both free areas, so the family gets the maximum Part A ($6,139.30 + $970.90 supplement) and maximum Part B for a youngest child aged 5–18 ($3,646.35 + $478.15) — $11,234.70 a year, or $235.48 a fortnight of Part A.
Couple, three children, $130,000 family income
The $20,268.45 maximum falls by $10,789.40 (20% of income between $69,131 and $123,078) to $9,479.05, then by 30% of the $6,922 above $123,078 ($2,076.60) to $7,402.45. Part B is nil because 20% of the partner’s income above $7,154 exceeds the $4,124.50 Part B rate.
Frequently asked questions
How much is Family Tax Benefit Part A in 2026–27?+
The maximum Part A rate is $6,139.30 a year for each child under 13 and $7,989.85 for each child aged 13–15 or 16–19 in secondary school, plus an end-of-year supplement of up to $970.90 per child if family income is $80,000 or less.
What is the income limit for FTB Part A?+
Part A starts reducing at family income above $69,131 (20c per dollar) and the base rate reduces by 30c per dollar above $123,078. The point where it stops completely depends on how many children you have and their ages.
Who can get FTB Part B?+
Single parents with a child under 19 (or 18 if not in secondary school) and couples with a youngest child under 13, as long as the primary earner’s income is $124,327 or less. For couples, the secondary earner can earn $7,154 before Part B reduces.
When are FTB supplements paid?+
The Part A and Part B supplements are paid as a lump sum after the end of the financial year, once you and your partner have lodged tax returns (or told Centrelink you do not need to) and your FTB has been reconciled.
Is Family Tax Benefit taxable?+
No. Family Tax Benefit is not taxable income and does not need to be included in your tax return, but your family’s adjusted taxable income determines how much FTB you receive.
What if I estimate my income wrong?+
FTB is paid on your income estimate and reconciled against your actual income after the year ends. If you underestimate, you may have to repay a debt; if you overestimate, you will get a top-up payment.
