How Family Tax Benefit works
Family Tax Benefit (FTB) is a two-part payment from Services Australia that helps with the cost of raising children. Part A is paid for each eligible child and is tested on your combined family income. Part B is an extra payment for single parents and couples with one main income, paid per family. Many families receive both. The calculator above estimates each part, then shows the yearly supplements separately because those are paid as a lump sum after the financial year ends.
FTB Part A rates (2026–27)
Part A is paid per child. The rate you get sits somewhere between the base rate and the maximum, depending on your income.
| Child’s age | Maximum / fortnight | Base / fortnight |
|---|
| Child 0 to 12 years | $235.48 | $75.60 |
| Child 13 to 15 years | $306.46 | $75.60 |
| Child 16 to 19 (in study) | $306.46 | $75.60 |
Plus a yearly Part A supplement of up to $970.90 per child if your family income is $80,000 or less.
The Part A income test
You get the maximum Part A rate if your family’s adjusted taxable income is $69,131 or less. Above that, your rate reduces by 20 cents for each dollar over $69,131, until it reaches the base rate. Once your income passes $123,078, the base rate itself reduces by 30 cents per dollar until it hits nil. So the income at which Part A stops depends on how many children you have and how old they are: for one child under 13, that’s about $129,648.
FTB Part B rates (2026–27)
| Age of youngest child | Maximum / fortnight |
|---|
| Youngest child 0 to 4 years | $200.34 |
| Youngest child 5 to 18 years | $139.86 |
Plus a yearly Part B supplement of up to $478.15 per family.
The Part B income test
Part B has two parts to its income test. First, the primary earner (or a single parent) must earn $124,327 or less, or no Part B is payable. Then, for couples, the secondary earner can make up to $7,154 a year before Part B starts reducing by 20 cents per dollar. Part B cuts out once the secondary earner reaches $35,661 (youngest under 5) or $27,777 (youngest 5 to 13). Single parents aren’t subject to the second test, so they get the maximum rate under the income limit.
Worked example
A couple with two children aged 8 and 14, a combined income of $95,000 and a lower earner on $20,000. Part A works out to about $343 a fortnight (income sits in the 20-cent taper band). Part B, based on the youngest being 8, is about $41 a fortnight after the secondary earner test. That’s roughly $384 a fortnight in ongoing FTB, plus a Part B supplement of $478.15 after balancing. The Part A supplement doesn’t apply here because the family income is over $80,000.
Frequently asked questions
How much Family Tax Benefit will I get?
It depends on your family's adjusted taxable income, how many children you have and their ages, and whether you're single or a couple. FTB Part A is paid per child (up to $235.48 a fortnight for a child under 13, or $306.46 for a child 13 to 19 in study). FTB Part B is paid per family (up to $200.34 a fortnight when your youngest is under 5, or $139.86 when they're 5 to 18). Enter your details above for an estimate of both, per fortnight and per year.
What is the difference between Family Tax Benefit Part A and Part B?
Part A is paid for each eligible child and is designed to help with the general cost of raising kids. It's tested on your whole family's income. Part B is an extra payment for single-parent families and couples with one main income, aimed at families where a parent stays home or works part-time. Part B is paid per family, not per child, and looks at the higher earner's income plus a separate test on the lower earner. You can get both at once.
What are the income limits for Family Tax Benefit?
For Part A, you get the maximum rate if your family's adjusted taxable income is $69,131 or less. Above that, the rate reduces by 20 cents per dollar down to the base rate, then by 30 cents per dollar over $123,078 until it reaches nil. The exact cut-off depends on how many children you have and their ages. For Part B, you can't get it if the primary earner (or a single parent) earns more than $124,327 a year.
Does my partner's income count for Family Tax Benefit?
Yes. Part A uses your combined family adjusted taxable income, so both partners' incomes count. Part B works differently: it uses the higher earner's income for the main limit ($124,327), then applies a second test to the lower earner. The lower earner can make up to $7,154 a year before Part B starts reducing by 20 cents per dollar. Part B cuts out once the lower earner reaches $35,661 (youngest under 5) or $27,777 (youngest 5 to 13).
Does everyone get Family Tax Benefit Part B?
No. Part B is targeted at single parents and single-income or low-second-income couples. A couple can only get Part B while their youngest child is under 13, and not at all if the higher earner makes more than $124,327. Single parents can get it until the end of the year their youngest turns 18 (16 to 18 must be in full-time secondary study), as long as their income is $124,327 or less.
What are the FTB supplements?
On top of the fortnightly payments, there are two yearly supplements. The Part A supplement is up to $970.90 per child, paid only if your family income is $80,000 or less. The Part B supplement is up to $478.15 per family. Both are paid as a lump sum after the end of the financial year, once Services Australia balances your payments against your actual income. This calculator shows them separately from your ongoing fortnightly amount.
Is this FTB calculator accurate?
It uses the current 2026-27 maximum and base rates, income-free areas and tapers published by Services Australia, and it reproduces the official income cut-off limits. It's a close estimate for a straightforward family. It doesn't model shared care percentages, Rent Assistance, the Energy Supplement, child support under the Maintenance Income Test, or part-year eligibility. Services Australia works out your actual entitlement, so treat this as a guide and confirm with them or through myGov.
