TFN vs ABN: What’s the Difference and Which One Do You Need

If you live or work in Australia, you would have probably heard of TFN (Tax File Number) and ABN (Australian Business Number) countless times and even heard people discussing their significance, similarities and why they’re needed in the first place. Issued by the Australian government, these two numbers are essential for taxation and business registration processes. Despite their importance, many individuals are still unsure about what the number stands for and which one to apply for. 

This blog clearly explains what TFN and ABN are, helps you understand the differences between them, and shows how expert guidance can help you choose the right one for your needs.

What is a TFN?

Issued by the Australian Taxation Office (ATO), a TFN is a 9-or sometimes 8 digit permanent reference number that serves as an identity for individuals usually living in Australia. The TFN is primarily used in the tax and superannuation system. Not owning a TFN in Australia is okay until you start earning, because without a TFN 

• You cannot apply for the government’s benefits and special allowances. 
• You may not be eligible to lodge a tax return online. 
• You cannot apply for an ABN, risking your limitations as a business or sole trader. 
• Your employer may withhold a portion of your pay as taxes. 

What is an ABN?

An ABN is an 11-digit unique number issued to businesses for their dealings with the public, government and other entities. Having an ABN is mandatory in Australia, for without this number you can’t register a business, claim GST or even set up a website domain. From small businesses to large corporations, every business needs an ABN, as it serves as the official identity of your business.

As stated, a TFN is mostly required by individuals living and earning in Australia and by people who deal with the Australian taxation system. Apart from this, you will need a TFN if you are,

• An employee, with a TFN you will have the right amount of tax is withheld from your pay. 
• A sole trader or freelancer to report your income earned through your work. 
• A superannuation account holder who tracks their contributions regularly.

• Any business, regardless of its size, to avoid having the highest tax withheld by other businesses. 
• When you need to register for GST and claim credits.
• To operate as an independent contractor.

Overall, a TFN helps you with tax purposes, while an ABN supports your business endeavors.
