If you pay or receive Child Support and prepare your own tax return, you need to lodge it with the ATO by 31 October.
Keeping your income information up to date helps us work out your Child Support assessment using the most accurate information.
If you're not required to lodge a tax return, you need to:
- submit a Non-Lodgment Advice with the ATO
- confirm your income with Child Support.
