Applying annual private apportionment

Last updated 31 October 2022

How to apply annual private apportionment on your activity statement.


If eligible to use annual private apportionment at any time, you can do so at any time. You can start at the beginning of the next tax period for which an activity statement is due.

You don't need to notify us if you choose to use annual private apportionment, however you must keep records that include both of the following:

  • the date you chose annual private apportionment
  • the date it took effect.

Example: Date of effect of annual private apportionment

Daniella reports and pays GST monthly, and her November activity statement is due on 21 December.

If Daniella decides at any time between 22 November and 21 December that she wants to use annual private apportionment, the date of effect is 1 November.

End of example
