How much does it cost to register for an ABN?

Our service fee is $149 AUD for ABN registration. Optional add-ons include GST registration ($29), PAYG withholding registration ($29), and Business Name registration ($149). There are no hidden government fees on top of these prices.

How long does it take to get my ABN?

In most cases your ABN is issued within 1 business day of submitting your application. We'll email you your ABN as soon as it's confirmed by the ATO.

What information do I need to apply?

You'll need your Tax File Number (TFN), date of birth, residential address, and details about your business activity. The application takes around 5-10 minutes to complete.

Can I start using my ABN straight away?

Yes. Once the ATO issues your ABN it is active immediately and you can start invoicing clients, registering for GST, and using it for all business purposes.

Why use a registered agent instead of applying directly?

The Australian Business Register allows individuals to apply for an ABN directly at no charge. However, the process requires accurate completion of a government form — errors, inconsistencies, or missing information can result in delays of up to 28 days, or in the application being declined.

ApplicationAU reviews your application before it is lodged. A Registered Tax Agent checks that the information is complete and consistent with ATO requirements, and submits the application on your behalf. If the ATO raises questions or requests additional information, we handle that communication directly — you do not need to deal with the ATO yourself.

This is particularly valuable if you have a complex situation — for example, if you have recently lodged a tax return, if your identity details are difficult to verify automatically, or if you are registering a company or trust rather than as an individual. These are the scenarios most likely to trigger manual review when applied for directly.

The service is also useful if you simply want to get the application right the first time, without navigating an unfamiliar government portal.
