Compare your child support collection options
You can choose between 3 ways to receive or pay child support.
Self employed parents
If you're self employed and pay child support through us, you can use most payment methods.
Change of circumstances
We need to know about changes that could affect your child support.
When care arrangements for a child change
If you are sharing care and the amount of time you care for your child changes, this may affect your payments and services.
Changing your assessment in special circumstances
We can change your child support if we’re satisfied there are special circumstances and the change would be fair to both parents and the child.
Disputed care interim periods
An interim period may apply if care is disputed. This is when parents stop following a written care agreement and disagree with that change.
Child support when your child turns 18
Normally child support stops when the child turns 18. If your child is in secondary education you can apply to extend it to the end of the school year.
Child support and military deployment
When you leave Australia on military deployment you need to tell us your new details. This is so we can make sure your child support is still accurate.
Child support if you go to prison
You must tell us if you go to prison. This is so we can make sure your child support is accurate.
While living outside Australia
In some cases we can help separated parents with child support arrangements for their children when one parent lives in another country.
When the other parent lives outside Australia
If you are paying child support to the other parent who lives outside Australia, we will collect your payments and pass them onto the other country.
When a receiving parent gets paid money they are not owed, they will have an overpayment.
Objections to child support decisions
If you don’t agree with a decision we’ve made you may be able to object.
