father walking with childChild support in Australia is a financial arrangement designed to provide assistance for the care and upbringing of children when their parents are separated or divorced. The Australian government has established guidelines to determine the amount of child support that a parent is required to pay based on their income and the needs of the child.


The annual rate of child support is determined using a formula, and the most convenient method to calculate it is by employing a child support calculator by Services Australia.


When the ATO issues an income tax assessment that necessitates a fresh evaluation by Child Support, a new child support period commences. Typically, the new income tax assessment pertains to the parent’s taxable income from the most recent relevant year of income with regards to the new child support period.


To calculate child support for each child, follow these eight steps:


  1. Determine the child support income for each parent.
  2. Combine the child support incomes of both parents to obtain a total combined child support income.
  3. Divide each parent’s individual child support income by the combined child support income to obtain an income percentage.
  4. Calculate the care percentage for each parent in relation to the child.
  5. Determine the cost percentage of the child.
  6. Subtract the cost percentage from the income percentage for each parent. This result is referred to as the child support income.
  7. If the child support income is a negative percentage, it implies that the parent may receive child support as their portion of the child’s costs is already being adequately covered by the amount of care they provide.
  8. If the child support income is a positive percentage, the parent is required to pay child support since they are not meeting their full share of the child’s costs through direct care. Steps 7 and 8 are applicable only when the child support percentage is positive.


Different care arrangements for each child may result in distinct child support percentages for the care of the child.


Next, calculate the costs associated with each child.


Finally, determine the final child support amount by multiplying the positive child support percentage by the child’s costs. This final figure represents the child support payment that the paying parent must transfer to the other parent.


At the start of each calendar year, the fundamental values used in the calculation of child support arrangements undergo changes.

What is the Minimum Child Support Payment in Australia?

He minimum child support payment in Australia is determined by the Child Support Agency (CSA), which is responsible for administering child support matters. The specific amount varies depending on several factors, including the income of the paying parent, the number of children involved, and the level of care provided by each parent.


The CSA uses a formula called the Child Support Assessment to calculate the minimum amount of child support payable. It takes into account the income of both parents, the costs of raising children, and other relevant factors.

What is the Maximum Child Support in Australia?

The maximum child support payment in Australia is not explicitly defined by a specific cap. Instead, the amount of child support payable is determined based on the income of the paying parent and the needs of the child. The Child Support Assessment formula takes into consideration the income of the paying parent up to a certain threshold, beyond which the percentage of income used for the child support calculation decreases.


This means that as the income of the paying parent increases, the percentage of their income that is required to be paid as child support decreases. However, there is no defined maximum child support amount that can be ordered by the court or the CSA.


Starting from January 1, 2023, if the combined income of the parties exceeds $206,310, the maximum child support amount to be divided between them for children aged 12 years and below is as follows:


  • $25,169 for one child
  • $39,198 for two children
  • $49,515 for three children


For children aged 13 and above, the shared child support between the parents is:


  • $31,359 for one child
  • $47,451 for two children
  • $58,592 for three children


In the case of children of different ages, the maximum child support to be shared between the parents is:


  • $44,325 for two children
  • $54,053 for three children


If the children have greater needs and one parent has the means to contribute more, the parties have two options:

They can negotiate a higher amount and formalize it through a child support agreement.


One parent can seek to modify the assessment by applying for a change in the child support arrangement.


Child support calculations can be complex, and there are various factors that can influence the final amount. These factors may include the cost of childcare, healthcare, education, and other expenses related to the child’s well-being. The CSA considers these factors when determining the appropriate level of child support.
