Application for Post Separation Income to be Excluded form (CS4120)

Use this form to apply to exclude additional income from your child support assessment. This is income you earned after you separated from the child's other parent.

This must be income you have earned in addition to income you earned before your separation. For example it doesn't include:

  • income from a second job you had before separation
  • overtime if you were already doing overtime before separation, or
  • standard pay rises
