Question: Is it possible to lodge a tax return through LodgeiT for a trust that does not have an ABN? The trust does not run a business so does not have or need an ABN.

Answer: Should be possible if you are a tax agent AND the trust has a TFN.

ATO requires an ABN in order to lodge Trust Tax Return without tax agent.

You should probably find a tax agent or lodge a paper form. 

Note, ABN is essential to avoid pay as you go (PAYG) tax on payments received and to ensure compliance with tax obligations. Additionally, having an ABN helps in confirming your business identity to others when ordering and invoicing, and it is required to access government online services.
