How it works
Family Tax Benefit helps with the cost of raising kids, in two parts: Part A is paid for each child, and Part B gives extra help to single parents and to couples living mostly on one income. Put in your family's income, how many children you have and their ages, and any shared care, and this estimates both.
- 1Enter your combined family taxable income for the financial year.
- 2Specify the number of dependent children in your care.
- 3List the ages of each child, separated by a comma.
- 4Select your relationship status (single or couple).
- 5If applicable, enter your shared care percentage.
- 6Read the estimate of Part A and Part B for the year; it updates as you type.
- 7Check the chart for where your family income sits on the Part A taper.
Worked examples
Couple sharing care (50%)
Alex and Sam are a couple with shared care (50%) for their 3 children, family income $110,000. Their payment is prorated for shared care and subject to a family income test.
Estimate will show reduced FTB Part A and likely no Part B due to income and care split.
Questions people ask
- What is the Family Tax Benefit (FTB)?
- FTB is a government payment to help families with the cost of raising children, split into Part A (per child) and Part B (additional help for single parents and some couples).
- How is FTB Part A calculated?
- FTB Part A depends on your family income and the number and ages of your dependent children. The more you earn, the lower the payment after a threshold.
- Who is eligible for FTB Part B?
- Single parents, carers, and some couples on lower incomes with the youngest child under a threshold age (usually under 13).
- Can I get both FTB and Child Care Subsidy (CCS)?
- Yes, but your combined payments and eligibility may be affected by income and care arrangements.
- Does shared care reduce FTB payments?
- Yes. Payments are prorated based on shared care percentage. You must declare shared care arrangements to Services Australia.
