Can I Have More Than One ABN?

Yes, you can have more than one ABN (Australian Business Number) in Australia, but there are specific conditions and guidelines you must follow. Taking help from experienced Tax Consultant like ISM Accountants can help you more. Here’s an overview based on the search results:

Multiple ABNs Under One Business Structure

Theoretically, it is possible to register multiple ABNs linked to a single business structure. For instance, if you operate a company that has both a retail store and a wholesale division, you could apply for separate ABNs for each division. However, this is not common practice and may expose you to operational risks, as liabilities and risks from one business could affect the other if they are not legally separated.

Conditions for Having More Than One ABN

Same Business Structure: You can only register multiple ABNs if the businesses operate under the same legal structure. If you have different structures (e.g., a sole trader and a company), you must apply for separate ABNs for each structure.
Multiple Business Names: You can register multiple business names under one ABN, provided they all operate under the same business structure. This can help streamline operations and reduce registration costs.

Whether it is for ABN, ACN, TFN or any services, you can explore our services.

Registering for an ABN in Australia

Through a licensed tax agency or the Australian Business Register (ABR), you can apply online for an ABN.

You must first determine your company’s structure and determine whether your enterprise is eligible for an ABN before starting the application process. You can check your eligibility for an ABN by going to the Australian Business Register website.
For the application, gather data such as tax file numbers, previously held ABNs, ACNs, the legal name of the firm, business contact information, and more.
Then, to register for an ABN, visit the ABR website’s ABN application portal and follow the instructions.

For example, if you run a small cafe, you would apply for an ABN to legally operate and manage your business finances.

How to Register for an ACN in Australia?

The ACN registration process is straightforward but involves paying a small fee. This number is essential for legal and financial documentation. Establishing and registering a corporation is the initial step in the more involved process of obtaining an ACN.

Here’s a broad rundown of the procedure:

Initially, you must determine if starting a business is the best choice for you or if an alternative kind of organisational structure would be preferable.
Select a company name that is unique and not already in use, then reserve it.
Choose the operational or governing structure for your business.
Recognise and fulfill your legal commitments.
Obtain the signatures of the individuals who will serve as the company’s directors, secretaries, and members.
Use the Business Registration Service (BRS) provided by the Australian government to register the company.
Your firm will ultimately be registered upon processing of your application, and you will be issued an ACN.

How to update or Cancel your ABN?

If you decide to close your business or no longer need your ABN, it’s up to you to let the Australian Business Register (ABR) know. Once you notify them, they’ll handle the cancellation for you.

It’s also your responsibility to keep your ABN details up to date while your business is still active. This includes:

Your business address
Contact information
Your associates (like directors or shareholders)
GST registration status

If anything changes, you have 28 days to update those details on the register.

When you’re ready to cancel your ABN, make sure you officially inform the ABR. Only then will your ABN be shown as “cancelled” on the public register. It’s an important step to avoid any confusion or legal issues down the track.

How to update or cancel your ACN?

Changes to your company details must be updated with ASIC. To cancel your ACN, you must deregister your company with ASIC.

Here are the key points about updating or cancelling your ACN (Australian Company Number):

If your company structure changes, you may need to update or cancel your ACN by informing the Australian Securities and Investments Commission (ASIC). This is separate from updating your ABN.
To update your ACN details, you can lodge forms with ASIC online or by mail. Common changes include updating your company name, registered office address, principal place of business, or officeholder details.
To cancel your ACN, you will need to lodge a Form 6010 Notification of ceasing to carry on business in Australia with ASIC if your company has ceased operations or been deregistered.
Failure to keep your ACN details up-to-date can result in penalties from ASIC. It’s important to notify them of any changes within the required timeframes.
If your company has been deregistered, you will need to apply for reinstatement of registration with ASIC before you can reactivate your ACN. Fees may apply.
Updating or cancelling your ABN is a separate process handled by the Australian Business Register (ABR). The ABN and ACN are different identifiers for businesses and companies.

Is an ABN and TFN the Same?

No, an ABN (Australian Business Number) and a TFN (Tax File Number) are not the same. The taxation system in Australia requires two unique identifiers because they each fulfill separate functions.

- Helps with GST registration and claiming tax deductions.
TFN (Tax File Number):
- A personal identification number for tax purposes.
- Used for employment, tax returns, and government benefits.
- Required by both individuals and businesses for tax reporting.

If you’re self-employed or running a business, you may need both an ABN and a TFN to comply with Australian tax regulations.
