Family Tax Benefit (FTB) helps eligible families with the cost of raising dependent children. It has two parts: Part A is generally based on the number and ages of children, while Part B may provide extra help to some single parents and families with one main income. Eligibility and payment rates can depend on your income, care arrangements, residency and other circumstances. You can check your situation and claim through myGov or the Services Australia website, which makes the final assessment.
