We assess your land tax quarterly and base the assessment on the status of the property as of four key dates: 1 July, 1 October, 1 January and 1 April each year.
The assessments are for each whole quarter; there is no daily pro-rated land tax liability within a quarter.

How is land tax calculated?
The amount of land tax you pay is made up of two components: a fixed charge and a valuation charge.
From 1 July 2023, the fixed charge for land tax is $1,535.
The total valuation charge for the year is calculated by applying a rating factor to the average unimproved value (AUV). The AUV is the average of the property’s unimproved value over a number of years. Since 2021-22, AUVs have been averaged over the last 5 years.
For example, the AUV for 2023-24 is the average of the property's unimproved value over 2019, 2020, 2021, 2022 and 2023.
For new or recent properties, the AUV can be the property’s unimproved value or an average of unimproved values over period the property has existed. These properties include those where a parcel of land has been subject to a Lease Variation Charge.

Marginal rates that apply to property AUV
AUV | Percentage (%) |
Up to $150,000 | 0.54% of the AUV of the property |
From $150,000 to $275,000 | $810 plus 0.64% of the part of the AUV that is more than $150,000 |
From $275,001 to $2,000,000 | $1,610 plus 1.12% of the part of the AUV that is more than $275,000 |
$2,000,000 and higher | $20,930 plus 1.14% of the part of the AUV that is more than $2,000,000 |
This figure is then divided into quarters. The amount for each quarter depends on the number of days in the quarter.
Quarter | Non-leap year (%) | Leap year (%) |
|---|---|---|
July to September | 25.2054 | 25.1366 |
October to December | 25.2054 | 25.1366 |
January to March | 24.6575 | 24.8633 |
April to June | 24.9315 | 24.8633 |
Unit title properties
The valuation charge calculation for residential unit properties starts the same as for houses, with a rating factor applied to the AUV of the residential portion of the total unit complex (100% if it’s a fully residential complex).
This figure is then multiplied by the unit entitlement percentage, which is the percentage that a unit holds compared with the overall unit complex. For example, if there are four equal-sized units on the block, each would have a valuation charge of 25 per cent of the overall valuation charge for the unit complex.
