Family Tax Benefit (FTB) can help eligible families with the cost of raising children and may include Part A, Part B, or both. Eligibility and payment rates can depend on your family income, children’s ages, care arrangements, residence and other circumstances, so the amount is not the same for everyone. You generally need to estimate your income and tell Services Australia about changes, with payments usually balanced after the end of the financial year using your actual income.
