Land tax is payable on the taxable value of an owner's land. The taxable value is the relevant unimproved value of the land less exemptions and deductions.
If capping does not apply, the relevant unimproved value is the lesser of:
a. the unimproved value of the land that applies for the financial year; or
b. the averaged unimproved value of the land for the financial year.
If capping applies the relevant unimproved value is 150% of the relevant unimproved value of the land for the previous financial year. Capping applies for the 2007-08, 2008-09 and 2009-10 financial years only.
To obtain item (b), the unimproved value of the land for the current and previous two years is averaged. If the unimproved value for the three years is not available, an averaging factor (a percentage of the current year's value) is used.
