How child support assessment works.
In this section
The assessment formula
The child support assessment formula looks at circumstances to work out how child support should be paid.
To be eligible for a child support assessment you meet residence rules and be the legal parent or non-parent carer of the child.
How your percentage of care affects your child support payments
We consider each parent or non-parent carer’s care of the child as part of our child support assessment. This is their percentage of care.
How your income affects your payment
We consider each parent’s income equally when we make a child support assessment. We don’t use income from non-parent carers.
This formula is for parents with only 1 child support assessment.
A child support assessment period can be up to 15 months.
Your child is turning 18 and is still at school
Normally child support stops when your child turns 18.
Assessment for same-sex parents
You and the other person on your child support assessment application must be the child's parent or non-parent carer.
Assessments for non-parent carers
If you care for a child and you're not their parent, you may be able to get child support from one or both parents.
Parents with 2 or more assessments
We work out how much child support you pay or receive if you have 2 or more families from past relationships.
Assessments for parents with second families
If you have children from a new family, we reflect this in your assessment.
Fixed and minimum assessments
We can base some child support assessments on a fixed rate or a minimum rate.
We can make a child support assessment if at least 1 parent lives in Australia.
A parenting plan is a written agreement with the other parent. It sets rules for things like how much time the children will spend with each parent.
What ends an assessment
There are a few reasons why a child support assessment will end.
