It's your client’s responsibility to update their Australian business number (ABN) details within 28 days of becoming aware of changes.
Once your client is registered, their ABN details become part of the ABR.
It is important that ABN details are kept up-to-date. Businesses use this information to check your client is operating or to verify their GST status.
ABN details are also used by a range of government agencies to plan for community services and infrastructure development that can benefit business.
The fastest way to update your client’s details is via Tax professionals services using AUSkey.
Alternatively you can update your client’s details by contacting us.
The changes will take effect immediately once they are entered in the ABR.
Check the ABR Dashboard for current information about ABR performance.
