How we assess the amount of child support you need to pay or receive. The formula we use to work it out is in Australian law.
In this section
The assessment formula
The child support assessment formula looks at your circumstances to work out how much child support should be paid.
This formula is for parents with only 1 child support assessment.
How your percentage of care affects your 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.
Fixed and minimum assessments
We can base some child support assessments on a fixed rate or a minimum rate.
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.
Care percentage estimator
The care estimator is a tool that calculates your care percentage.
Child support and your Family Tax Benefit Part A
Any child support you receive can affect how much Family Tax Benefit Part A you get.
