When your child turns 18 and you have a child support assessment

Normally child support stops when your child turns 18.

You can apply to extend it to the end of the school year if your child will be in full time secondary education when they turn 18.

If you have a child support agreement, you may be able to extend it. Contact us to find out.

You can also apply to have a relevant dependent child included in your assessment after they turn 18. They’ll need to be in full time secondary education.

When to apply

You need to apply while the child’s 17. We’ll remind you to do this before they turn 18.

We can only accept an application after a child turns 18 in limited circumstances.

Family Tax Benefit
