What document is essential when submitting a TFN application?

The essential document when submitting a TFN application is personal identification details including your name and date of birth. This information is crucial as it helps to accurately identify you as an individual needing a Tax File Number (TFN). The TFN serves as a unique identifier for tax administration purposes, and having your full name and date of birth ensures that the application is processed correctly and linked to your identity in government records.

While documents like a driver’s license, a tax return from the previous year, or proof of residency can be relevant in various contexts, they do not hold the fundamental role that personal identification details do at the application stage. The primary goal of the application is to establish your identity clearly and unambiguously to ensure the TFN is assigned to the right individual.
