Step-by-Step Guide to Update Your ABN Details

To quickly update your ABN details, use ABR online services. Here's how:

1. Access the Australian Business Register (ABR)

The ABR allows you to update information about eligible associates, such as:

• Trustees

• Directors

• Public officers

• Office bearers of a club or association

Here’s how to get started:

1. Visit the ABR Website – Start by visiting the Australian Business Register (ABR) website to access the relevant sections for ABN updates.

2. Navigate to Update Section – Once on the ABR website, locate the section specifically for updating ABN details. This ensures you can make necessary changes efficiently.

2. Log In to Your ABR Account

Ensuring secure access to your ABR account helps maintain the integrity of your business information.

By using myGovID linked to the ABN in Relationship Authorisation Manager (RAM), you guarantee that only authorized individuals can update your details.

Once you click on the “Update your ABN” option from the ABR website, you’ll be transferred to the myGovID page.

Here’s how to log in effectively:

1. Enter Email Address – Input the email address used to set up your myGovID. A code will be generated.

2. Open myGovID App – On your smart device, open the myGovID app. Log in and enter the four-digit code that appears on the login screen into the pop-up box within the app.

Tap "Accept."

3. Select the ABN to Update

After logging in, you’ll see an ABN summary that provides a snapshot of your business information, such as:

• ABN number – Your unique 11-digit Australian Business Number.

• ABN status – The current status of your ABN (active, canceled, etc.).

• Business Name – The registered name of your business.

• Entity Type – The type of business entity (e.g., sole trader, company).

On the right side of the ABN summary window, you’ll find a menu with options such as:

Depending on what needs updating, select the suitable section from the menu.

4. Update Your Details

To start updating your ABN details, first decide what needs updating. This could include your business name, address, or contact information:

• If the provided information is correct, no further action is needed.

• If the data is outdated, update the relevant sections and proceed.

Verifying Business Address

Even if your business address hasn't changed since you registered for an ABN, it's important to confirm that ABR has the correct location listed in the register.

Your main business address should be a physical street address, not a post office box or your tax/BAS agent’s address.

However, you can still use a different postal address for receiving communications.

If your business operates from multiple locations, ensure these addresses are updated, too.

Additional Business Activities

You can register up to 4 additional business activities along with their respective Australian and New Zealand Standard Industrial Classification (ANZSIC) codes.

For example, if you run a fitness center, your main activity might be Sports and Physical Recreation Instruction (8211).

If you also offer a health cafe, massage services, and a retail shop, you can add the following ANZSIC codes:

• Cafes and Restaurants (4511)

• Other Allied Health Services (8539)

• Sport and Camping Equipment Retailing (4241)

Steps to Add Business Activities:

1. Use your myGovID and select “Update ABN record.”

2. Select ANZSIC and Business Details option.

3. Provide a short description of your business activity to find the best match.

4. Select the Category from the drop-down menu.

5. Based on your selection, the ANZSIC code and ANZSIC code description will be auto-updated. 

6. To add more activities, repeat these steps from step 2.

5. Review and Submit Changes

Once you have made all necessary changes, it’s time to review and submit them.

First, it is important to double-check all the updated information.

Accuracy at this stage ensures that there are no errors that could affect your business operations.

Finally, submit the changes through the ABR portal. This action finalizes your updates and ensures your business information is up-to-date.

Follow these steps to submit changes to your ABN details:

1. Select Declaration — After making changes, go to the declaration section.

2. Accept the Declaration — Tick the box to confirm that you accept the declaration.

Keeping your ABN details updated is also essential to avoid penalties and maintain your business’s credibility.

Here are some key points to consider when updating your ABN details.

1. Timing of Updates

Every day, businesses access ABN Lookup to verify information.

If these steps don't resolve the issue, contact ATO directly for further assistance.

• Error Code 45047 (422): Indicates an issue with the authentication process, often due to incorrect or incomplete information provided during identity verification.
