What form is required to apply for a TFN?

To apply for a Tax File Number (TFN) in Australia, the required form is indeed the Tax File Number application form. This specific form is designed for individuals to officially request their unique tax identification number, which is essential for various tax-related processes, including filing tax returns and dealing with the Australian Taxation Office (ATO).

The TFN application form captures essential personal information such as your name, address, date of birth, and identifies your eligibility for a TFN. It is a straightforward procedure aimed at ensuring that individuals can easily obtain their TFN for compliance with tax obligations and other financial transactions.

While the other options may relate to tax processes, they do not serve the purpose of applying for a TFN directly. The Certificate of Tax Registration and the Income Tax Declaration form pertain to different aspects of tax compliance, whereas the Tax Identification Number application generally applies to systems outside of the Australian context. Therefore, the application for a TFN specifically requires the use of the Tax File Number application form.
