Who can apply for a TFN in Australia?
Before you apply, it’s important to identify which category you fall into because your TFN application method depends entirely on your residency status and identification.
Choosing the right path from the start can save you time and prevent unnecessary delays.
The ATO broadly groups applicants into three categories:
1. Australian citizens with a Strong Digital ID (myID)
If you’re an Australian citizen aged 15 or older and have a Strong Digital Identity (myID), you can apply for your TFN completely online.
This is the fastest and most efficient option, as:
- No in-person verification is required
- Your identity is verified digitally
- Processing is typically quicker than other methods
Best for: individuals who want a quick, fully online TFN application without extra steps.
2. Australian residents (without a Strong Digital ID)
If you’re an Australian resident for tax purposes but don’t have a Strong Digital ID, you can still apply but your application will include an identity verification step.
This usually involves:
- Starting your application online
- Verifying your identity through Australia Post or an approved centre
What to expect: a slightly longer process due to manual identity checks, but still straightforward if documents are correct.
3. Permanent migrants and temporary visitors
If you’ve recently arrived in Australia or hold a visa with work rights, you can apply for a TFN once you’re physically in Australia.
You’ll need to:
- Provide passport and visa details
- Identity is verified automatically through immigration records (no documents required in most cases)
Important: processing may take longer, and your TFN is usually sent by post so timing your application early is key if you’re planning to work or start earning soon.
