TFN requirements
A TFN, or Tax File Number, is a personal reference number in Australia's tax and superannuation systems. It is free to apply for a TFN, and it is yours for life—even if you change jobs, move, or change your name.
Applying for a TFN requires providing proof of identity and, in some cases, proof of visa status. The specific requirements depend on your residency status and whether you are applying online or by paper form.
Online Application Requirements
If you are an Australian citizen or permanent migrant with an Australian passport and are 15 years or older, you can apply for a TFN online. This can be done through the myGov website or, if you have a work rights visa, via the Individual Auto Registration (IAR) system.
Paper Form Application Requirements
If you are an Australian resident without an Australian passport, you will need to apply for a TFN using a paper form. This also applies to permanent migrants and temporary visitors who are unable to use the IAR system due to visa restrictions or other reasons.
The paper form requires current, original proof of identity documents, which can be submitted at a Services Australia service centre or sent by mail to the address on the form.
Protecting Your TFN
Once you have received your TFN, it is important to keep it safe and only disclose it to people or organisations that require it for legitimate reasons, such as the Australian Taxation Office (ATO) when discussing your tax records. You should contact the ATO as soon as possible if you believe your TFN has been lost, stolen, or is being misused.

TFN safety
Keeping Your TFN Safe
Your Tax File Number (TFN) is a unique, personal reference number used for taxation and superannuation purposes in Australia. It is important to keep your TFN safe and secure to prevent unauthorised access or misuse. The Australian Taxation Office (ATO) provides guidelines on how to protect your TFN and personal information.
Limited Disclosure
Only disclose your TFN to authorised individuals, organisations, or agencies that require it for legitimate reasons. This typically includes the ATO when discussing your tax records, your employer, bank, or superannuation fund. If you are unsure whether an entity is authorised to request your TFN, you can verify this with the ATO.
Understanding Your Rights
When an entity requests your TFN, they must provide certain information to you, including the reason for collecting it and any potential consequences of not providing it. You have the right to withhold your TFN, but there may be financial implications, such as higher tax rates or difficulties in receiving personal assistance payments.
Reporting Misuse or Loss
If you believe your TFN has been lost, stolen, or misused, it is crucial to report it as soon as possible. You can contact the ATO and OAIC (Office of the Australian Information Commissioner) to report unauthorised access or misuse of your TFN information. Additionally, if you suspect your TFN information has been mishandled by an individual, organisation, or agency, you should contact them directly to make a complaint.
Secure Storage and Destruction
Keep your TFN information in a safe place to prevent unauthorised access. When disposing of documents containing your TFN, shred or destroy them to protect your privacy. While there are rules governing the handling of TFN information, taking personal precautions is essential to safeguard your identity.
By following these guidelines and staying vigilant, you can help ensure the safety and security of your TFN, protecting your personal and financial information in Australia.

TFN and taxation
A tax file number (TFN) is a personal reference number in Australia's tax and superannuation systems. It is used to help individuals lodge tax returns and ensure that the correct amount of tax is withheld from payments made to them. TFNs are issued by the Australian Taxation Office (ATO) and are free to apply for.
While it is not mandatory to have a TFN, not having one can result in higher tax withholding rates on payments received from employers or financial institutions. Additionally, a TFN is required to apply for government benefits or allowances in Australia. It is important to note that individuals should only disclose their TFN to authorised parties, such as the ATO when discussing tax records, to prevent identity fraud or scams.
Australian citizens aged 15 or older with an Australian passport can apply for a TFN online using a Digital ID. For those without an Australian passport or who are under 15, there are alternative application methods available. Applicants typically receive their TFN within 28 days of submitting their completed application and required identity documents.
It is important to keep TFN details secure and up to date. Individuals can update their TFN registration details, such as name, date of birth, bank details, and gender, by contacting the ATO. If an individual suspects their TFN has been lost, stolen, or misused, they should notify the ATO as soon as possible.

TFN and identity fraud
A tax file number (TFN) is a personal reference number in the tax and superannuation systems in Australia. It is used to ensure correct tax and superannuation payments. TFNs are issued to individuals by the Australian Taxation Office (ATO) and are kept for life, even if an individual changes their name, job, or moves interstate or overseas.
TFNs are important personal details that should be protected and kept secure. If someone else obtains your TFN, they can commit identity fraud or scams. This can include committing refund fraud in your name, accessing your myGov account to steal your tax refund, or stealing your superannuation. Scammers can also sell your identity to organised crime groups on the dark web. If your identity is stolen, you may experience stress, anxiety, and a sense of vulnerability, knowing that someone else can exploit your personal information at any time. It can also lead to significant personal and professional challenges, such as impacting your credit rating and making it difficult to prove your identity and obtain new identity documents.
If you suspect that your TFN has been stolen or misused, you should contact the ATO as soon as possible. The ATO will investigate and place extra protection on your ATO account. You should also report all tax-related security issues to the ATO and identity theft and fraud to your state or territory police. To protect yourself from identity fraud, only give your TFN to organisations or people who have a legitimate need for it, such as your tax agent, current employer, or bank. Be cautious of unsolicited emails or SMS messages with links to online portals, as these could be scammers attempting to steal your personal information or plant malware on your devices. Always access online services by directly typing the URL into a browser, rather than clicking on links.
