Introduction
If you’re planning to work in Australia, applying for a Tax File Number (TFN) should be one of your first priorities.
A TFN is a unique identification number issued by the Australian Taxation Office (ATO). It allows employers to pay you correctly and ensures you are taxed at the appropriate rate.
Without a TFN, you can still work in Australia, but your employer may withhold significantly more tax from your wages.
