Apply for a TFN in Australia (2026): Online Application, Processing Time & Delays

Last updated: April 2026

If you want to work in Australia, one of the first things you should do is apply for a Tax File Number (TFN).

Quick FAQ

  • Cost? - Free
  • Apply online? - Yes
  • Processing time? - Usually 7–28 days
  • Need a job first? - No
  • Can you work before TFN arrives? - Yes, but higher tax may be withheld temporarily

For most new arrivals, getting a TFN should be a week one priority.

Without a TFN:

  • You may pay higher withholding tax
  • Payroll setup can be delayed
  • Tax returns become harder
  • Superannuation records may not match properly

What Is a TFN?

A Tax File Number (TFN) is your personal tax identifier issued by the Australian Taxation Office (ATO).

You use it for:

  • Employment payroll
  • Lodging tax returns
  • Superannuation accounts
  • Some banking and government processes

Think of it as your main tax identity in Australia.


Who Needs a TFN?

You should apply if you:

  • Are starting a job in Australia
  • Plan to work casually, part-time or full-time
  • Need to lodge a tax return
  • Want your superannuation tracked correctly

This commonly includes:

  • Permanent residents
  • Temporary visa holders
  • International students
  • Working holiday makers

Do You Need a Job Offer First?

No.

You do not need a job offer before applying for a TFN.

Many people apply immediately after arriving in Australia.


What You Need Before Applying

Prepare these details before starting:

  • Valid passport
  • Australian visa
  • Australian residential address
  • Contact number or email
  • Personal identity details

Use details exactly as shown on your passport.


How to Apply for a TFN in Australia

Step 1: Use the Official ATO Website

Use the Australian Taxation Office TFN application for:

Foreign passport holders, permanent migrants and temporary visitors

Do not pay third-party websites.

A TFN application is free.


Step 2: Complete the Online Form

You will usually enter:

  • Passport details
  • Visa details
  • Australian address
  • Date of arrival
  • Contact information

Most applicants finish in 10 to 15 minutes.


Step 3: Submit the Application

After submission:

  • You receive a reference number
  • Your application enters processing
  • No payment is required

Save your confirmation details.


TFN Processing Time in Australia (2026)

Official processing can take up to 28 days.

Typical real-world timeframes:

  • Fast cases: 7–14 days
  • Normal cases: 2–4 weeks
  • Delayed cases: Longer if details need review

Your TFN is commonly sent to your nominated address.


Why TFN Applications Get Delayed

1. Incorrect Passport Details

Even small spelling errors can slow processing.

2. Wrong Address

If mail cannot be delivered, you may miss the notice.

3. Duplicate Applications

Submitting again often causes delays.

4. Visa Record Mismatch

If immigration records do not match entered details, extra checks may occur.


Can You Work Without a TFN?

Yes, but delaying is usually a mistake.

If you do not provide a TFN to your employer, tax may be withheld at a higher rate until updated.

That can reduce your take-home pay temporarily.


What To Do After You Receive Your TFN

Once issued:

  1. Give it to your employer
  2. Add it to your super fund
  3. Keep it private and secure
  4. Store it in your tax records

Do not share your TFN publicly.


TFN vs ABN: Important Difference

Many newcomers confuse these.

TFN

Used by individuals for employment and tax.

ABN

Used by businesses, sole traders and some contractors.

If you are an employee, you usually need a TFN.

If you run a business or invoice clients, you may also need an ABN.


How Much Tax Will You Pay?

Once your TFN is active, tax depends on your income.
