Experts warn that many parents in Australia avoid their full child support obligations by failing to submit tax returns, with some engaging in cash-in-hand work or using business structures to reduce payments. Services Australia referred over 168,000 parents to the ATO in 2022-23 for overdue returns. Non-compliance with tax lodgements is being recognised as a form of economic abuse, disproportionately affecting women, who make up over 80% of child support recipients. Women’s Legal Services Australia is calling for urgent reforms, including stricter enforcement and a government child support guarantee to address these ongoing financial challenges.
