Key point
Do not ignore an overdue obligation. Identify each missing year, gather the records and confirm whether a return or non-lodgment advice is required.
Start with the oldest records
Collect Income Statements, bank interest, business records and prior ATO correspondence for every outstanding year.
Penalties and support
Penalties may apply depending on the circumstances. Lodging voluntarily and seeking help early is generally better than waiting.
Before you apply
Check that your information covers the correct Australian income year. Keep source documents and do not enter TFNs, passport numbers or bank credentials in ordinary messages.
