The maximum Part A is $235.48 a fortnight for each child under 13 and $306.46 for each child 13 to 19. Part B is up to $200.34 a fortnight when the youngest child is under 5, and $139.86 when they’re older. Both reduce as income goes up.
What’s the difference between Part A and Part B?
Part A is paid per child and tested on your family’s combined income. Part B is a per-family payment for single parents and couples with one main income, tested on the higher earner and, for couples, the lower earner’s income.
When are the end-of-year supplements paid?
After the year ends and your family’s payments are balanced, once your tax returns are lodged. The Part A supplement is only paid if family income is $80,000 or less.
