The ACT Revenue Office assesses land tax quarterly and bases the assessment on the status of the property as of four key dates: 1 July, 1 October, 1 January and 1 April. The assessments are for each whole quarter; there’s no daily pro-rated land tax liability within a quarter.
If you own residential property that’s been rented but is temporarily vacant on the land tax’s due date, you still owe land tax unless:
- the vacancy continues for at least 91 consecutive days and;
- you tell the Commissioner for ACT Revenue in writing that the property has not been rented in that quarter.
Calculating your land tax
Use our land tax calculator to get an estimate of the land tax you owe. You can also use it to calculate an estimate on your rates and any other relevant levies you may owe.
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.
The fixed charge for land tax is $1,145.
The valuation charge is calculated by applying a rating factor to the average unimproved value (AUV), which is the average of the property’s unimproved value over the last three years (see Table 1 below). For example, the AUV for 2017–18 is the average of the property’s unimproved value over 2015, 2016, and 2017. So, the ultimate calculation looks like this:
Standard properties = fixed charge + (AUV x rating factors)
Together, the fixed charge and the rate of the AUV add up to the total land tax amount for the year, which is then divided into quarters. The amount for each quarter depends on the number of days in the quarter (see Table 2 below ).
Unit title properties 2017-18
Charges for unit title properties in 2017-18 have been calculated on the Average Unimproved Value of the residential portion of the total unit complex and your residential unit entitlement. The formula used to calculate charges for residential units is:
((Residential AUV of the Master Property x Marginal Rates) x Unit Entitlement + Fixed Charge) x percentage of the quarter.
Please note that the unit entitlement used in the above calculation methods is the individual unit portion of the total aggregate of residential properties in the complex.
Please contact the ACT Revenue Office for further assistance.

A Certificate of Rates, Land Tax and Other Charges enables property owners applying for the certificate to calculate the amount of rates, land tax and other charges they should allow for at a property transfer settlement.
The ACT Revenue Office is not responsible for calculating these settlement balances; the new owners are responsible for these calculations and for paying any owed money following the settlement and transfer of a property.
From 1 July 2017, the fee for a Certificate of Rates, Land Tax and Other Charges is $112.
To apply for a Certificate of Rates, Land Tax and Other Charges:
- lodge your application form
- complete the necessary declaration stating that the certificate is for conveyancing purposes only
- pay the $112 fee.
The ACT Revenue Office will then issue your certificate.
When we process your application, we can deliver your certificate to you by post, fax depending on what you specify in your application.
