Property tax in Australia can be quite complicated, and can vary from state to state, so it is important to seek advice from a tax advisor regarding your personal situation as you prepare to buy a new home.
However, here is an introduction to the basic taxes relevant when buying a property in Australia:
GST: a good and services tax of 10% applies to purchases of real estate like many other products.
Stamp duty: stamp duty is a state tax which is charged on property purchases, and can be a fixed rate or as a percentage of value.
Land tax: is also a state tax, which is charged annually to land owners.
Capital gains tax: this applies to the money you receive as part of selling a property, and is calculated as part of your income tax.
