Revising activity statements

Find out how you can avoid delays to activity statement processing when lodging a revision.

Last updated 20 October 2021

Use the correct DIN

Original and revised activity statements must have different document identification numbers (DINs).

If we processed an activity statement, then receive lodgment of another activity statement with the same DIN, it can lead to incorrect refunds and account balances, as well as processing delays.

Note: If you send your client a copy of a lodged revised activity statement, make sure they do not lodge it again.

Revise online

Before lodging a revision, make sure your client's original activity statement was lodged and processed.

Complete a revised activity statement using Online services for agents or the practitioner lodgment service (PLS).

Refer to your PLS user guide or the Online services for agents user guide lodgments section for instructions on lodging activity statement revisions.

This video explains how to revise an activity statement in Online services for agents.
