Child support assessments with second families

If you have relevant dependent children in your care for 128 nights or more in a year, or in a shared care arrangement, an amount for their support may be deducted from your income when calculating your child support.

A child assessed in another child support case can’t be a relevant dependent child.

A relevant dependent child can be:

  • your biological child
  • your adopted child
  • your stepchild if a court has made a court order that you have a duty to maintain your stepchild
  • your child born as a result of an artificial conception procedure where
    • you and the other parent were in a married or de facto relationship at the time of the artificial conception procedure, and
    • you and the other parent consented to the artificial conception procedure, and
    • any person who provided genetic material consented to the genetic material being used in the artificial conception procedure
  • your child born as a result of an artificial conception procedure where
    • you and the other parent were in a married or de facto relationship at the time of the artificial conception procedure, and
    • under a prescribed commonwealth, state, or territory law you are a parent of the child, or
  • your child born as a result of a surrogacy arrangement, and a court has made an order under a prescribed law of a state or territory declaring you to be a parent of the child

We work out your relevant dependent child amount using the cost of children table.

Either parent can have children from a new family recognised in this way. We only use your income. Your new partner's income isn’t taken into account when we work out the relevant dependent amount.

Stepchildren

A child’s biological parents are responsible for financially supporting their child. Sometimes, neither biological parent can contribute to the costs of their child. This could be due to illness, death or caring responsibilities of the parent.

If neither parent can financially support their child, a stepparent who makes child support payments and also cares for a stepchild can apply to change their assessment in special circumstances to have their child support payments reviewed.
