2.4.3 The Steps Involved in Making a Child Support Assessment
The Registrar must follow specified steps when making an administrative assessment of child support.
CSA Act section 5, Part 5
When working out the annual rate of child support payable for a child using formula 1, the basic formula, the Registrar must use the following steps:
- Step 1. Work out each parent's child support income (CSA Act section 41) - see 2.4.4.
- Step 2. Work out the parents' combined child support income (CSA Act section 42) - see 2.4.7.
- Step 3. Work out each parent's income percentage (CSA Act section 55B) - see 2.4.7.
- Step 4. Work out each parent's percentage of care for the child (CSA Act section 48) - see 2.4.5.
- Step 5. Work out each parent's cost percentage for the child (CSA Act section 55C) - see 2.4.5.
- Step 6. Work out each parent's child support percentage for the child (CSA Act section 55D) - see 2.4.5.
- Step 7. Work out the costs of the child under sections 55G and 55H of the CSA Act - see 2.4.6.
- Step 8. If a parent has a positive child support percentage under step 6, the annual rate of child support payable by the parent for the child for the day is worked out using the formula:
Child support percentage × Costs of the child
An example of the calculation of an assessment using the basic formula is included at 2.4.7, where formula 1 is explained.
There are additional steps required when one of the other 5 formulas is used. Information about these additional steps is included in 2.4.8 for cases where there is a non-parent carer in a single child support assessment; in 2.4.9 where at least 1 parent has multiple child support cases and in 2.4.10 where the income of 1 parent only is used in the assessment.
