Using the volume model to calculate petroleum royalty

The volume model applies to petroleum produced from 1 October 2020.

Royalty is calculated by applying a prescribed rate to the volume of liable petroleum produced during a return period.

Different rates apply to the 4 classes of petroleum:

  • domestic gas
  • supply gas
  • project gas
  • liquid petroleum.

Transitional arrangements

Royalty for petroleum that was produced but not disposed of before 1 October 2020 must be paid for in the annual return period ending 30 September 2020.

Penalties and interest

Calculating the correct amount of royalty is important because we will impose a penalty of 75% of any understated liability. Unpaid tax interest will also apply to late payments.
