A TFN is used for tax and superannuation purposes. If you are working in Australia, you will usually need to provide your TFN to your employer.
What is a Tax File Number?
A Tax File Number, or TFN, is a personal reference number used by the Australian Taxation Office.
Your TFN is used for tax, superannuation, and other government-related purposes.
The Australian Taxation Office states that a TFN is free to apply for and is yours for life. You only need to apply once. (Australian Taxation Office)
Why do I need a TFN?
If you are working in Australia, you will usually need a TFN so your employer can withhold the correct amount of tax from your pay.
You may also need a TFN to:
start employment
lodge a tax return
manage your superannuation
apply for an Australian Business Number, also known as an ABN
deal with the Australian Taxation Office
If you do not provide a TFN to your employer, you may have more tax withheld from your pay.
Can I apply for a TFN before travelling to Australia?
If you are a foreign passport holder, permanent migrant, or temporary visitor, you generally need to be located in Australia and hold a visa with work rights to apply for a TFN online. (Australian Taxation Office)
This means many visa holders apply for their TFN after they arrive in Australia.
If you are outside Australia, check the Australian Taxation Office guidance for people living outside Australia to understand which application process applies to your situation. (Australian Taxation Office)
How do I apply for a TFN?
You can apply for a TFN through the Australian Taxation Office.
How you apply depends on your circumstances, including whether you are:
an Australian resident
a foreign passport holder
a permanent migrant
a temporary visitor
living outside Australia
The Australian Taxation Office provides different TFN application options depending on your residency and visa status. (Australian Taxation Office)
When should I apply for a TFN?
If you are coming to Australia to work, it is a good idea to apply for your TFN as soon as you are eligible.
For many temporary visitors and permanent migrants, this means applying after arriving in Australia with a valid visa that allows work.
Applying early can help you be ready for employment and payroll setup.
Providing your TFN to an employer
When you start a job in Australia, your employer will usually ask you to complete a Tax File Number declaration.
You should provide your TFN to each employer you work for.
Your employer uses this information to calculate tax withheld from your pay and report your income correctly.
Keep your TFN secure
Your TFN is an important part of your identity.
Only provide your TFN when it is required for legitimate tax, employment, superannuation, or government purposes.
Avoid sharing your TFN casually or sending it through insecure channels.
