  • Child Support Guide for Australian Parents

    The Child Support Guide for Australian Parents is an adapted version of the Australian Government’s Child Support Guide. It takes a different approach to the government edition, which was “designed to assist decision makers administering social policy law.” Our Parents’ Guide is written for the benefit of parents. Sections contained in the government version have…

Assessment of child support ›

A child support assessment is the formal determination of how much child support is payable between parents. It usually comes from the standard formula applied by Services Australia.

  • Administrative Assessment

    Administrative assessment is the standard child support assessment made by Services Australia using the formula or a change of assessment.

  • Court order for child maintenance

    A court order for child maintenance is a court-set child support obligation, used where the standard administrative assessment does not apply.

Care arrangements ›

Care percentage is the share of time a parent looks after a child over a care period. It is almost always based on the number of nights the child stays with each parent.

  • Shared care

    Shared care means a parent has 35% to 65% care of a child. It affects cost recognition and whether child support is paid or received.

  • Below regular care

    Below regular care means 0 to 51 nights a year. The formula treats that parent as meeting none of the child’s costs through care directly.

Change of assessment ›

Change of Assessment (COA) is a way to adjust a child support assessment when the formula does not properly reflect a case situation. Either parent can apply.

  • Reason 8B

    Reason 8B allows child support to reflect a parent’s unrealised earning capacity where current income is lower than they could earn.

Enforcement and debt collection ›

Child support debt arises when assessed payments are not made and the case is being collected by Services Australia. The unpaid amount becomes a debt owed to the Commonwealth.

  • Agency collect

    Agency collect is a free option where Services Australia collects and transfers child support payments on behalf of the receiving parent.

  • Arrears

    Arrears are unpaid child support amounts recorded on an account. They become enforceable debts once registered for collection.

Formula for child support ›

The child support formula is also known as the basic formula and formula 1. It is a complex calculation that uses an income shares model to make a child support assessment.

  • Multi-case allowance

    Multi-case allowance is a deduction from income for other child support cases, reducing assessed income before payments are calculated.

  • Annualised MTAWE figure

    The annualised MTAWE figure underpins child support parameters, keeping income thresholds and costs aligned with wage growth each year.

Income for child support ›

Child support income is calculated from the taxable income of the parent. The main adjustment is to subtract a self-support amount in excess of $30k to determine income available to support children.

Objections and reviews ›

An objection is the first step if you believe a child support decision is wrong. It triggers an internal review by Services Australia, where a different officer reassesses the decision.

  • Administrative Review Tribunal

    The Administrative Review Tribunal reviews child support objection decisions independently and can affirm, vary, or replace the outcome.
