Quick answer: From 1 July 2026, Family Tax Benefit Part A pays up to $235.48 a fortnight for each child under 13 and $306.46 for each child aged 13-19 in secondary school, plus a $970.90 supplement per child after the year ends if family income is $80,000 or less. It falls by 20 cents for each dollar of family income over $69,131 until it reaches the base rate ($75.60 a fortnight per child), which falls by 30 cents a dollar over $123,078.
Part B pays up to $200.34 a fortnight when the youngest child is under 5 and $139.86 when older (to 13 for couples, 18 for single parents), if the main earner earns $124,327 or less; a couple's second earner can earn $7,154 before it reduces. Example: a couple on $90,000 and $20,000 with children aged 4 and 8 gets about $4,105 of Part A and $3,132 of Part B a year.

Renting? Add the Rent Assistance calculator. Paying for day care? The Child Care Subsidy calculator uses the same family income. Salary-packaging a car? Its reportable fringe benefits amount counts in adjusted taxable income — the FBT calculator shows the figure your employer will report. Single parent, or caring for someone as well? The Centrelink calculators page shows which other payments your family may be able to get alongside FTB. Not on the maximum rate of Part A, so no automatic Health Care Card? The Low Income Health Care Card calculator checks the separate 8-week income test, with a higher limit for each child.

Part A: the maximum rate per child (plus the supplement if family income is $80,000 or less) is reduced by 20% of income over $69,131 and 30% of income over $123,078, but not below the base rate; the base rate is reduced by 30% of income over $123,078. The higher result is paid. Part B: the standard rate for your youngest child's age plus the $478.15 supplement, reduced for couples by 20% of the second earner's income over $7,154, and nil if the main earner has more than $124,327. Rates and thresholds from the DSS Family Assistance Guide, checked 25 September 2026.
Not included: Rent Assistance, the maintenance income test for child support, shared care, the newborn supplement, multiple birth allowance and the grandfathered energy supplement. If you or your partner get an income support payment, you get the maximum rate of Part A. The fortnightly figure is an estimate — Services Australia pays on your income estimate and balances it after the year ends.

❓ Frequently Asked Questions
How much Family Tax Benefit will I get?
It depends on your family's adjusted taxable income and your children's ages. Maximum Part A is $6,139 a year per child under 13 and $7,990 per child aged 13-19 in secondary school, plus the $970.90 supplement.
A single parent on $50,000 with a 3-year-old gets about $12,812 a year in Part A and Part B combined, including supplements.
What is the income limit for Family Tax Benefit?
There is no single cut-off for Part A: it tapers from $69,131 (20c in the dollar) and again from $123,078 (30c), so the limit rises with the number and ages of your children. Part B stops once the main earner's income is above $124,327.
The Part A supplement is only paid if family income is $80,000 or less.
What counts as income for FTB?
Adjusted taxable income (ATI): taxable income plus reportable fringe benefits, reportable super contributions (such as salary sacrifice), total net investment losses, tax-free pensions or benefits and target foreign income, minus child support you pay. For couples, Part A uses both partners' ATI combined.
When are the FTB supplements paid?
After the end of the financial year, once FTB is balanced against your actual income — so you must lodge a tax return (or tell Services Australia you don't need to). The supplements can be used to repay an FTB or Child Care Subsidy debt.
Can I get Rent Assistance with FTB?
Yes — if you rent privately and get more than the base rate of FTB Part A, Rent Assistance can be added to your Part A. Use the Rent Assistance calculator for the amount.
