ATO / SBR BAS Lodgement

The instructions in this article relate to ATO SBR Client. The icon may be located on your StrataMax Desktop or found using the StrataMax Search.

The ATO SBR Client is an integrated module designed to assist with the lodgement of a saved StrataMax BAS directly with the Australian Taxation Office (ATO). 

ATO / SBR Video

The following video was prepared demonstrates the SBR functionality of lodging Business Activity Statements with the ATO 

What is Standard Business Reporting?

SBR (Standard Business Reporting) is an enabling technology that can be used in many ways saving the community and government agencies time and money. SBR helps businesses reduce the time spent collating information, filling in forms and submitting reports to government.

The SBR Integration integrates with StrataMax and will perform the following tasks:

  1. Retrieve outstanding BAS reports to complete.
  2. Prefill the data available from the ATO and saved StrataMax BAS for the selected period.
  3. Submit Prelodge BAS to check for errors.
  4. Submit completed BAS reports.
  5. List previously Lodged BAS reports (lodged via SBR).

The ATO SBR Client will allow BAS’s to be lodged for both StrataMax and GLMax, if being utilised.

ATO Credentials

Credentials are created in the form of a saved encrypted file, which is obtained through the ATO. This is called an 'SBR Keystore file' and must be available and accessible when StrataMax is open in order for the ATO SBR Client to be used.

To obtain an SBR Keystore file, this article has included the below links to assist. However, any issues or queries about this process should be forwarded to the ATO directly.

When the ATO SBR Client is used to lodge BAS, the SBR Keystore file requires a password. When this is entered, the process involves multiple steps and the password is not stored, meaning the password must be re-entered each time a BAS is lodged.

StrataMax is an installed software product (not hosted), which may need to be advised if discussions with the ATO are required.

StrataMax ATO SBR Client

The ATO SBR Client allows users to easily and quickly lodge saved Business Activity Statements to the ATO. Before using SBR, ensure that the current completed BAS has been saved in the Business Activity Statement menu.

  1. Open the ATO SBR Client menu.
  2. Select the required Drive to use from the drop down list (This will default to the first drive).
  3. Click the Search button (magnifying glass) next to the Keys field.
  4. This will open Windows Explorer to locate the ABR Keystore file.


If StrataMax is installed on a remote server or virtual machine, this file will need to be saved or transferred there so that it is accessible to be used in the ATO SBR Client menu in StrataMax. The office IT support provider will be able to assist with the transfer of this file if necessary.

BAS Types that cannot be lodged using ATO SBR Client

Some BAS types cannot be lodged using the ATO SBR Client menu. If these BAS appear under the 'New' section when the Find Pending button is clicked, they should be deleted and lodged manually with the ATO either by using MyGovID or with a paper BAS.

GST / PAYG with variable lodgement frequency

Any buildings that have a different GST frequency (e.g. quarterly), to the PAYG reporting (e.g. monthly) frequency, the ATO SBR Client will not be able to select the appropriate document from the list web service.

If a building is detected with this condition, the ATO SBR Client will display an error message in the log and not import the building when the Find Pending button is used.


Account Groups

Any buildings that utilise account groups in StrataMax, cannot lodge a BAS using the ATO SBR Client menu. This is due to the possibility that the building may require multiple ABN.

Finding Pending - Business Activity Statement

When the StrataMax ATO SBR Client screen is opened, the screen will display a list of options for Find Pending is the first step in preparing the BAS that are available to be lodged, based on whether the building is GST Registered in StrataMax.

  1. Review the To and From dates to ensure that they represent the BAS period due to be lodged.
  2. Click the Find Pending button.
  3. When the list of buildings registered for GST appears, tag the required buildings and click OK.
  4. The selected BAS will now appear in the list with a status of ‘New’.

Prefilling – Business Activity Statement

Prefilling the BAS will contact the ATO service and will return a response containing details of the selected BAS that the ATO has available. This can be done using the Bulk Prefill button or each individual BAS.

Prefill one BAS

To prefill the details for a selected BAS:

  1. Select and right-click the required BAS.
  2. Select Prefill and OK.
  3. The BAS will now appear in the list with a status of ‘Prefilled’.

  1. The system will return a prefill complete message.
  2. All prefilled BAS will now be listed with a status of ‘Prefilled’.

Items that have not changed status will have reported details of any errors which can be reviewed by clicking the Log button.

Viewing Prefilled Statement

Once the ATO SBR Client has prefilled a BAS, it can be viewed under the Prefilled section. The BAS should be checked to ensure the data is correct and matches the saved BAS for the same period.

  1. Expand the Prefilled section of the list by clicking the drop-down arrow.
  2. Select and right-click the required BAS, and click View.

  • PAYG Withholding Tax
  • FBT

There are several fields that are prefilled from the ATO:

  • Document Identification Number
  • Customer Ref (PRN) Payment Reference Number
  • Form type
  • Completion Time

The preview is read-only and if there are discrepancies then the BAS may need to be deleted in the ATO SBR Client. If changes are required, the PAYG or BAS may just need to be edited or may have to be deleted, corrected and saved again.

Deleting Prefilled Statement

If there are changes that need to be made to any Pending or Prefilled BAS statement, the BAS will need to be deleted and loaded again into the ATO SBR Client, once the changes have been made to the BAS in StrataMax and saved again.

Troubleshooting Error Messages

Editing a Branch Number

A branch is formed where a business entity separately registers its branch to suit the structural, management and accounting arrangements of the organisation. When an entity registers a branch for GST or PAYG purposes, the entity is called the 'parent entity'. This may require the branch number to be edited from the default number 1, most likely to a 2.

The ‘Prefill’ stage may log a message similar to the below:

  • Access to the Activity Statement is not available. Contact the Tax Office. Logging into the Relationship Authorisation Manager (website) may assist to identify the branch number required to be reported and then can be amended.

Manually edit the branch number within SBR (saved BAS)

Login to ATO MyGovID and check the Branch number and edit if varies from the default stored '1'.

To Edit a already saved BAS Statement for a selected BAS:

  1. Highlight the BAS that you want to change the branch number for.
  2. Right Click on the BAS.
  3. Select ‘Edit’ option.

4.Edit to correct to the expected branch number, save and close. Re-try to pre-fill.

Please Note: if you have amended the branch number, this may be saved for all future BAS periods by editing the ABN Branch field in BAS Info Editor - see below.

Amend Branch number to populate automatically in ATO SBR (future BAS's)

If identified that a branch number is not the default of ‘1’ then the branch number can be entered into BAS Info Edit, this number will reflect in future saved BAS's for ATO SBR Lodgement. To set this follow the below steps:

  1. Navigate to BAS Info Editor.
  2. Edit an existing BAS info configuration.
  3. Change the branch code to ‘1’ or ‘2’ for example (blank will default to ‘1’).
  4. If there are no installment details for the select building, enter as 0.00 for option 1.
  5. If prompted select 'Yes' to save amount as 0.00.
  6. Close BAS Info Edit once complete.

Please note: Do not format the branch number as ‘001’ or ‘002’ as this will prevent lodgement.

When reviewing in Business Activity Statement, the branch Code will show on the Business Activity Statement.

BAS Reporting Methods

Simpler BAS & Full Reporting

ATO SBR Client must know to lodge either using the Simpler BAS method or Full Reporting method BAS:

  • Simpler BAS – lodging BAS Statement without labels G2, G3, G10, G11 (annual turnover of less than $10 million).
  • Full Reporting – lodging BAS Statement with all labels available (annual turnover of more than $10 million).

Reporting method configuration settings have been added to BAS Info Editor to allow for the reporting method to be set, otherwise ATO may reject lodgements for buildings that need to lodge a full BAS with all the extra BAS Labels. To configure the BAS Reporting method follow the below steps:

  1. Navigate to ‘BAS Info Editor’.
  2. The Tax Instalment information will need to be completed using Edit.
  3. Click on ‘Reporting Method’ icon.
  4. The system will switch between Simpler and Full Reporting.

Please Note: The default reporting method is Simpler BAS. If there are no installment details for the select building, enter as 0.00 for option 1.

Deleting a BAS in StrataMax

Note: When a BAS has been lodged through the ATO SBR Client, it cannot be deleted. If amendments are required, this should be completed using MyGovID. Rules apply for validation when deleting BAS Statements within StrataMax:

  • If ‘Find Pending’ has not been done in ATO SBR Client for a Bas Period – the StrataMax BAS Statement can be deleted / amended as required.
  • If ‘Find Pending’ is done in ATO SBR Client and the building BAS period has been tagged it will not allow you to delete the BAS in StrataMax.
  • If ‘Find Pending’ is done and the user deletes the SBR Record from ATO SBR Client (so it no longer appears in the SBR List) it will then allow the user to delete the BAS in StrataMax.
  • If the BAS has been lodged through SBR, it will not allow users to delete the SBR record nor allow it to be deleted in the StrataMax BAS.
  1. Business Activity Statement, Select a Past BAS, then highlight the last saved period.
  2. Right click and select 'Enable BAS Delete'.
  3. Select the now enabled 'Delete' button to remove the transactions and the saved BAS records.

If the message below appears review the ATO SBR Client as detailed above to remove any pending BAS data prior to amending in StrataMax.
