Australians pay tax so our government can provide services to our community, ranging from hospitals, schools and roads to recycling centres, national parks and even your local swimming pool.
The main tax you'll pay is income tax, which is charged on income you receive, such as salary and wages, investment income and business income. At the end of the income year (30 June), most people need to lodge an annual tax return.
The amount of income tax you pay is linked to how much you earn and whether you're an Australian resident. The more you earn, the higher your rate of tax.
Before you start work, or soon after, you may need to get a tax file number (TFN). You don't have to have a TFN, but you pay more tax if you don't have one.
You can apply for a TFN from the Australian Taxation Office.
