Correcting GST errors

If the GST error occurred on or after 1 July 2012

If you made a credit error on an activity statement for a reporting period that starts on or after 1 July 2012, you can correct the GST error on a later activity statement which starts within the four year period of review of the assessed GST net amount for the earlier reporting period that contains the GST error.

The period of review starts on the day we give you a notice of assessment and ends four years from the day after the notice of assessment is given. An assessment of your GST net amount is generally made on the day you lodge your activity statement. The activity statement is taken to be the notice of assessment given on the same day.

Example 4: Four year period of review

ABC Ltd, a monthly lodger, made a GST error in the September 2013 reporting period that resulted in an overstatement of its assessed net amount for that reporting period. As that activity statement was lodged and the net amount assessed on 1 October 2013, ABC Ltd can correct that GST error on an activity statement for a reporting period that starts between 1 October 2013 and 2 October 2017.
