Cancel your client’s ABN
You should request the cancellation of your client's ABN if their business:
- has been sold
- has closed down
- no longer operates in Australia or makes supplies connected with Australia
- experiences the death of the registered owner of the ABN.
Before you cancel your client's ABN, ensure all lodgment, reporting and payment obligations with any government agencies the business deals with are met.
If you want to cancel your client's pay as you go withholding, you must cancel it before you cancel the ABN.
