How Child Support Arrears Accumulate

Services Australia charges late payment penalties (LPP) on overdue child support. The penalty rate is the general interest charge rate set by the Australian Taxation Office, which changes quarterly and compounds over time.

Services Australia has extensive powers to collect child support arrears. These escalate based on debt amount and payment history:

Frequently Asked Questions

Frequently Asked Questions

What happens if I don't pay child support in Australia?

Services Australia can: deduct from wages, intercept tax refunds, issue departure prohibition orders (preventing international travel), register charges on property, and take legal action including bankruptcy proceedings. Late payment penalties accrue on unpaid balances. Arrears don't disappear—they follow you until paid, even surviving bankruptcy.

Can child support arrears be written off in Australia?

No. Child support debt cannot be written off through bankruptcy or time limits. It remains enforceable indefinitely. The only ways to reduce arrears: pay them, negotiate a payment plan, or apply for departure from assessment if circumstances have changed significantly.

How long do I have to pay child support arrears?

There is no time limit. Child support arrears remain enforceable forever, even after children turn 18. Services Australia can pursue collection decades later. Interest continues accruing until paid. The debt passes to your estate if you die.

Can late payment penalties be waived?

Yes. The Registrar can remit (waive) late payment penalties in full or in part if: circumstances were beyond your control and you took reasonable action to mitigate them; circumstances were within your control but you mitigated them and it's fair to remit; or there are special circumstances making it fair and reasonable. Contact Services Australia to request remission.

What if I genuinely can't afford to pay child support?

Apply immediately for a Change of Assessment or departure from assessment. Provide evidence of changed circumstances (job loss, illness, new dependents). Services Australia can reduce future payments, but you must apply—don't just stop paying. Get legal advice if your application is denied.
