How to Get Your TFN (Tax File Number) in Australia

Getting Your Tax File Number (TFN)

A Tax File Number is a nine-digit identifier the Australian Taxation Office (ATO) assigns to you. You need it to work legally in Australia, pay tax, claim deductions, and apply for government benefits. The good news is applying takes minutes. Processing takes 10-28 days depending on how you apply.

What Is a TFN?

A TFN is unique to you. The ATO uses it to track your income, tax, superannuation, and benefits. It's issued by the Australian Taxation Office, not a separate agency. Every worker in Australia has one, and your employer will ask for it before your first day.

Your TFN stays with you for life. If you leave Australia and return later, you use the same number.

Who Needs a TFN?

- All workers (employed or self-employed)
- Students claiming tax offsets
- Anyone receiving Centrelink benefits
- People with rental income or other taxable income
- Anyone opening a bank account (optional but recommended)

When to Apply

Apply as soon as possible after arrival, ideally within the first week. If you're starting work within days, apply on your first day. Your employer cannot legally pay you without requesting a TFN from you (they'll withhold tax at 45% + Medicare levy if you don't provide one).

What You'll Need

- Valid passport (original or certified copy)
- Visa details (visa number, grant date, conditions)
- Australian address (temporary or permanent)
- Proof of identity (driver's licence, Medicare card, or another government ID)
- Email address for correspondence

Method 1: Apply Online via myGov (Fastest)

Processing: 10-14 days. You'll get your TFN via email or text.

1. Create a myGov account if you don't have one. Visit my.gov.au. Use your email address and create a password.

2. Link the ATO service. Once logged in, link the Australian Taxation Office. You'll be asked security questions.

3. Go to "Tax file number" under ATO. Click the link or search "tax file number application."

4. Complete the form. You'll enter:
- Personal details (name, date of birth, gender)
- Passport number and visa details
- Australian address
- Contact phone number
- Employment details (not required yet; you can skip)

5. Review and submit. Check your details are correct. Submit the application.

6. Watch your inbox. You'll receive an email or text with your TFN within 10-14 days. The ATO may ask for more documents if needed.

7. Save your TFN. Write it down and store it safely. You'll use it for every tax and employment task.

Pros: Fastest method, instant confirmation, email notification.
Cons: Requires myGov account setup first.

Method 2: Apply Direct to the ATO

Processing: 4-8 weeks by post.

1. Download the form. Visit ato.gov.au and search "TF 11-05 Application for a tax file number." Download and print the form.

2. Complete the form. Fill in all sections. Provide:
- Full name, date of birth, gender
- Passport number (and copy)
- Visa details and grant date
- Australian address
- Contact details

3. Get your documents certified. Take your passport to a Justice of the Peace (JP) or lawyer. Ask them to certify that your passport copy matches the original. This usually costs AUD 10-20.

4. Mail the form. Send to:
- Australian Taxation Office
- TFN Unit
- GPO Box 9990
- Your State Capital

Include certified passport copy.

5. Wait for response. The ATO will post your TFN to you within 4-8 weeks. Mail delivery adds 1-2 weeks.

Pros: No internet needed, paper backup.
Cons: Slowest method, mail delays, certification required.

Common Problems and Solutions

"I submitted my TFN application online, but I haven't heard back in two weeks."

- Check your email (including spam). The ATO may send security questions. Reply within 7 days or your application may be delayed.
- Log in to myGov and check the status under "Tax file number." If it shows "more information needed," upload documents immediately.

"I can't create a myGov account without an Australian phone number."

- Use any phone number (even a temporary one). myGov uses phone for verification, not registration.
- If you have trouble, call the ATO on 13 28 61 and ask them to create a myGov account for you.

"My employer wants my TFN before I've received it."

- Provide a receipt or confirmation of your application. Most employers will accept this temporarily.
- Once your TFN arrives, give it to payroll immediately.

"I received a TFN but it doesn't match my application."

- Check the letter carefully. Sometimes numbers are misread. Call the ATO on 13 28 61 to confirm.
- If it's wrong, ask the ATO to reissue it.

After You Receive Your TFN

1. Keep it safe. Write it down or save it in your phone's notes (not email). Never share it casually.

2. Give it to your employer. Provide your TFN to payroll on your first day. Without it, you can't be paid correctly.

3. Link it to myGov. Log in to myGov and check that your TFN is active under ATO services. This lets you file tax returns online later.

4. Update your address if you move. Notify the ATO via myGov within 30 days. Tax documents are sent to this address.

5. Check it's on every payslip. Your employer should print your TFN on your payslip. Confirm this within your first week.

- On a skilled migration visa (189, 190, 491, etc.)

You are NOT eligible if you:
