From 1 July 2023, a windfall gains tax applies when land is rezoned by a planning scheme amendment resulting in a taxable value uplift to the land of more than $100,000. In determining the taxable value uplift, all land owned by the person or group and rezoned by the same planning scheme amendment is taken into account.

You may elect to defer payment of the windfall gains tax. You must apply to defer before the due date listed on your windfall gains tax assessment. You can apply by completing an online Smartform, by following the instructions below.

You may defer your windfall gains tax liability in its entirety, or in part. If deferring only part of the liability, you will need to specify what percentage of the liability you are deferring or alternatively specify the properties in respect of which you are deferring the liability. Note that any part of the liability that is not deferred must be paid by the due date specified on your assessment.

Deferral of windfall gains tax attracts interest at the applicable 10-year Treasury Corporation of Victoria bond rate.

The deferral will remain in place until whichever of the following occurs first:

• a dutiable transaction occurs in respect of the land, or
• a relevant acquisition occurs in respect of the landholder who owns the land, or
• 30 years after the rezoning event.

Certain dutiable transactions and relevant acquisitions will not cease deferral. A dutiable transaction that occurs as a result of the sale of the land will generally always cease deferral.

Where deferral ceases, full payment must be made within 30 days.
