Post separation income for Child Support parents 277-07100000



This document details how Child Support parents (either the payee or payer) can apply to have additional income earned after separation excluded from their child support assessment.

Definition of post separation income (PSI)

PSI is income earned by a parent:

  • after they separated from the other parent
  • not have been earned in the ordinary course of events and
  • is of a type that is reasonable to expect would not have been earned prior to separation

A customer can apply to have some of their PSI excluded from the child support assessment. The exclusion of PSI reduces the adjusted taxable income (ATI) for that parent.

There are several requirements that must be met to have income earned after separation excluded. This includes how long ago the parents separated and the type of income earned.

There is no requirement for the customer to show or incur the actual costs due to the separation or re-establishment.
