Land tax is an annual tax payable by owners of land (whether there is a building on it or not). Land tax is administered by each state or territory government and is applicable everywhere except for the Northern Territory.
The laws between each state are comparable, but there are some variations in how the taxes are calculated and the thresholds. The amount of land tax you pay is determined by the combined unimproved value of taxable property. If your or your business owns investment property, then it is likely you will need to pay land tax on it.
It is important that you know what your entitlements are, because land owned by some types of organisations can be exempt from land tax. And, your main home (i.e. permanent residence) is generally exempt from land tax.
