Family Tax Benefit (FTB) helps eligible families with the cost of raising children and has two parts: Part A and Part B, with different rules. Eligibility and payment rates can depend on your family income, children’s ages, care arrangements, residency and relationship status. You usually need to estimate your annual income, and Services Australia balances the payment after the end of the financial year, which can result in a top-up or an overpayment. Check the latest rules and claim through myGov or servicesaustralia.gov.au, as the final decision depends on your circumstances.
