The Family Tax Benefit (FTB) is a payment designed to help families with the cost of raising children. It has two parts: FTB Part A, which is income-tested and based on your family's circumstances, and FTB Part B, which provides extra support to single parents or lower-income families. To be eligible, you must meet certain residency and income requirements.
