What you need to know before starting work
If you’re planning to start working in Australia, one of the first things you’ll hear about is TFN.

TFN stands for Tax File Number, and it’s a personal identification number used for tax purposes in Australia.
You’ll need it when you get paid, when you lodge your tax return, and when your records are managed with the ATO (Australian Taxation Office).
Because of that, it’s a good idea to apply for it before you start working. The ATO also clearly states that applying for a TFN is free.
A lot of people are confused at first and ask things like:
- “Do I really need this?”
- “Is there a fee to apply?”
- “Can students or working holiday visa holders apply?”
But once you break it down, it’s actually not that complicated.
So here’s a simple guide to what TFN is, why you need it, who can apply, and how to get one.
Why do you need a TFN?
A TFN is your personal tax number in Australia.
Employers use it to process your salary, and you’ll also need it when you lodge your tax return or deal with anything related to the ATO.
Technically, you can start working without one, but it can make your tax situation more complicated.
That’s why most people apply for it before starting a job.
How much does it cost?
This is the easy part.
Applying for a TFN is completely free.
There’s no government fee involved, so if anyone tells you otherwise, be careful.
Who can apply?
Whether you can apply depends on your residency and visa status.
According to the ATO:
- Australian residents can apply at any age
- Australian citizens aged 15 or older with a Strong Digital ID (myID) can apply online and get it quickly
- Permanent residents and temporary visa holders can apply if they are in Australia with a valid visa and work rights
So if you’re on a student visa, working holiday visa, or any visa with work rights, you can usually apply without any issues.
How to apply for a TFN
The process depends on your situation.
1) Australian citizens with a Strong Digital ID (myID)
This is the fastest option.
You need:
- To be at least 15 years old
- A Strong identity strength Digital ID (myID)
If you meet these conditions, you can apply online and usually receive your TFN almost instantly.
2) Australian residents without Digital ID
If you can’t use myID, there are other options.
You can apply through:
- Australia Post
- Services Australia centres
- Or by submitting a paper application
So having a Digital ID is helpful, but not mandatory.
3) Visa holders (working holiday, student visa, etc.)
If you’re a foreign passport holder, permanent migrant, or temporary visitor, there’s a separate online application process.
You must be in Australia with a valid visa, such as:
- A permanent visa
- A visa with work rights
- A student visa
- Any visa that allows you to stay in Australia
This is the most common pathway for working holiday makers and students.
What do you need to prepare?
When applying online, you’ll generally need:
- Passport details
- Visa information
- An Australian address
- Email and contact details
Depending on your situation, additional identity checks may be required, so it’s best to follow the instructions on the ATO website carefully.
How long does it take?
This depends on how you apply.
- Australian citizens with Strong Digital ID → often receive it immediately
- Visa holders → can take up to around 28 days
If you don’t receive your TFN within that timeframe, you should contact the ATO.
So if you’re on a visa, it’s better to apply early and give yourself some time.
Applying for a TFN is one of the first steps when starting life and work in Australia.
It’s free, relatively simple, and essential for managing your income and taxes properly.
Especially if you’re on a working holiday or student visa, it’s something you should organise early so you don’t run into issues later.
