Chartered Accountants ANZ is reminding Australians who have yet to lodge their tax return for 2024-25 that they only have until 31 October to either self-lodge or appoint a tax agent.

"Millions of Australians choose to self-lodge their own tax returns to the Australian Tax Office, but 62 per cent of individual taxpayers rely on the expertise of a tax agent,” said CA ANZ tax expert Susan Franks said.

"There are benefits in using a chartered accountant who works as a registered tax agent, and the first is that you will be giving yourself more time to get your return ready."

The deadline for lodging a return when using a tax agent is either 31 March or 15 May the following year, depending on the tax liability of the last return you lodged.

As of last week, more than two million Australians had not yet submitted their tax return, according to the ATO.
