Understanding the Child Support & Family Tax Basics

Child support and family benefits can be complex. Here’s a simple breakdown.

What is Child Support?

Child support is a payment made from one parent to another to help with the costs of raising a child after a separation. The amount is based on each parent's income and the amount of time they care for the child. The goal is to ensure children receive a similar level of financial support as they would have if their parents were together.

What is Family Tax Benefit (FTB)?

FTB is a payment from the Australian Government to help with the costs of raising children. It comes in two parts:

  • FTB Part A: Paid for each eligible child. The amount depends on your family's income.
  • FTB Part B: An extra payment for single parents and some families with one main income to help with the costs of a young child.
