Australians who have put off filing their 2024/25 tax returns now have under a month do so. There is more than one way to prepare and lodge your return, including a paper tax return by mail, online through myTax or through a tax agent if you have more complex affairs. Paper tax returns can take up to 50 days to process. Aussies have four weeks to lodge their tax returns, or face a fine. “They’ll send texts, emails or calls claiming you owe money or are due a refund,” Chapman said.
