Attaché Payroll (Australia): Set up a payroll company with a new Australian Business Number (ABN)

Updated over a month ago

⚠️Important: For any ABN change requests, please email to APAC - Commercial Department [email protected].


If your ABN has changed, in order to correctly report payments to your employees and the ATO you will need to create a new payroll company data set. Decide which of the two scenarios described below best applies to your circumstances, then follow the appropriate steps. Whether you report via Single Touch Payroll (STP) or via payment summaries, you'll follow the same procedure, except for the STP-only steps which are clearly identified in the instructions.

📌Note: Depending on your individual circumstances and regardless of which scenario applies, you may need to terminate the employees in the original payroll company.


Scenario 1: Change in ABN at the end of the financial year

If the new ABN is only applicable in the new financial year AND all entitlements such as Annual Leave are being carried over AND you wish to keep all or some of the history currently in the data set, then follow the steps for scenario 1.

  • If you do not wish to keep any history, then use Scenario 2 irrespective of the time of year

  • If you wish to keep history but entitlements are not carrying over, then this method is applicable, but you will need to run a KFI, etc to remove entitlements. You should speak with your consultant before proceeding in this case.

To change your ABN at the end of the financial year, complete the following tasks (see detailed instructions for each task further below):

  1. Create a new company.

  2. Copy data files.

  3. Update the company details.

  4. (STP only) Notify the ATO that you authorise Attaché Software as your Hosted SBR Software Service Provider for the new ABN. Refer to Set up Standard Business Reporting for Single Touch Payroll.


Scenario 2: Change in ABN during the financial year

If your ABN is changing during the financial year, so that both ABNs need to report salary and wages to employees and the ATO in the same financial year, OR when all requirements for scenario 1 do not apply, follow the steps for scenario 2.

  • If you want to keep history and entitlements for a mid-year scenario, you can use scenario 1, but you will need to enter an adjustment pay for every employee to reverse out the total paid to them under the old ABN, and this must be done before connecting your new payroll company to your Attaché Online Organisation. You should speak with your consultant if you have too many employees to do this manually.

To change your ABN during the financial year, complete the following tasks see detailed instructions for each task further below):

  1. Create a new company.

  2. Copy the general setups.

  3. Update the company details.

  4. Copy payroll setups and Masterfile details.

  5. Update payroll options and tax scales.

  6. (STP only) See Connect the new company to your Attaché Online Organisation link above.

  7. (STP only) Notify the ATO that you authorise Attaché Software as your Hosted SBR Software Service Provider for the new ABN. See the Setting up Standard Business Reporting for Single Touch Payroll link above.
