As the tax return deadline has passed, Australians who missed it are now facing a hefty $313 fine, which specifically have significant implications for businesses dealing with debts.According to the Australian Tax Office (ATO), more than 7.9 million individuals have already submitted their tax returns, which is approximately 400,000 fewer than the previous year. This decline in early filings has put additional pressure on the last-minute stragglers.If individuals fail to submit their tax returns or engage with a tax agent by October 31, they will incur a $313 fine. This penalty escalates every 28 days, with a maximum cap of five times, meaning that those who procrastinate may end up paying a staggering total of $1,565.
