Frequently Asked Questions
What is the tax-free threshold in Australia?

The tax-free threshold for Australian residents is $18,200 for 2025–26. With the Low Income Tax Offset (LITO), the effective tax-free threshold rises to approximately $21,884. Non-residents and Working Holiday Makers are taxed from the first dollar of income at 32.5% and 15% respectively.

When must I lodge my Australian tax return?

Most Australians must lodge by 31 October each year. If you use a registered tax agent, you typically get an extension to May or June of the following year. Even if your employer withheld exactly the right amount of tax, lodging is worthwhile if you have deductions to claim — you may receive a significant refund.

What is PAYG withholding?

Pay As You Go (PAYG) withholding is the tax your employer deducts from each pay and sends to the ATO on your behalf. When you lodge your annual tax return, the ATO compares your total PAYG withheld against your actual tax liability — the difference is your tax refund or additional tax owing.

What records should I keep for tax deductions?

Keep receipts and records for 5 years after lodgement. For vehicle claims using the logbook method, maintain your logbook for the full 12-week period. The ATO can audit returns and deny deductions without supporting evidence. Use the ATO's myDeductions app to capture records throughout the year.
