Land tax

Calculating land tax

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.

The assessments are for each whole quarter; there’s no daily pro-rated land tax liability within a quarter.

From 1 July 2018, land tax is assessed on both vacant and rented properties that are not your principal place of residence.


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.

This calculator should be used by you as a guide only. The calculations done by you on this site do not take into account things such as interest or penalty tax that may apply. The calculations are GST exclusive.
The ACT Revenue Office regularly updates the calculators on its website in accordance with legislative requirements. No liability or responsibility is accepted by the Commissioner for ACT Revenue or the Australian Capital Territory for any errors in calculations which may arise as a result of errors made by you, errors due to technical issues, and errors arising due to issues beyond the control of the ACT Revenue Office.
In all circumstances, the calculations performed by you on this site do not replace the “Notice of Assessment” for any tax liability issued to you by the Commissioner for ACT Revenue.

Components of your land tax

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 $1,203.

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 2018–19 is the average of the property’s unimproved value  over 2016, 2017, and 2018. 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

If you own a residential unit, your valuation charge is based on the AUV of the residential portion of the total unit complex (100% if it’s a fully residential complex) and your unit entitlement.

The formula used for residential units is:

((Residential AUV of the Master Property x Marginal Rates) x Unit Entitlement + Fixed Charge) x percentage of the quarter.

Your unit entitlement is divided by the total unit entitlement of all residential units in the complex.

Transferring property

A Certificate of Rates, Land Tax and Other Charges provides parties to a property transfer, information to calculate the amount of rates, land tax and other charges as part of the property transfer settlement process.

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 2018, the fee for a Certificate of Rates, Land Tax and Other Charges is $117.

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 $117 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.
