Windfall Gains Tax

From 1 July 2023, many Victorian landowners whose land value increases due to the government’s decision to rezone will face the prospect of paying a significant and new tax to the State Revenue Office, called the “Windfall Gains Tax”.

The Windfall Gains Tax and State Taxation and Other Acts Further Amendment Act 2021 received Royal Asset on 30 November 2021.

The government has confirmed the implementation of a windfall gains tax (WGT) in Victoria. Any land in Victoria that is rezoned is subject to the WGT if the rezoning results in an increase in the value of the land of more than $100,000. The tax is to take effect from 1st July 2023 and the liability of this tax will be payable by landowners at the time when the rezoning occurs.  

The amount of windfall gain tax is levied upon all landholdings on aggregated taxable value uplift and is payable by the owner of the land when the rezoning occurs. This means if any owner/s hold multiple land subject to rezoning, the owner/s will be taxed at the rate equivalent to the combined amount of the total taxable value uplift. Members of group are jointly and severally liable for the tax.

What is a Windfall Gain Tax (WGT) Event?

A rezoning under the Planning and Environment Act 1987, however does not include rezoning:

  • Between schedules in the same zone (i.e. GRZ Schedule 1 –> GRZ Schedule 4)
  • Urban growth zone within a GAIC (growth areas infrastructure contribution) area or first rezoning after 1 July 2023 of land in the GAIC area before that date
    • Note:  Given that not all land in the urban growth boundary (UBG) is subject to GAIC, it should not be taken as an indication that WGT will not apply to land within UGB.
  • Causing land to be in a public land zone or between public land zones
  • Otherwise declared by the Treasurer to be excluded rezoning in the Government Gazette

What is the Taxable Value Uplift (TVU)?
